技术领域technical field

本发明涉及智能康复技术领域，尤其涉及一种脑卒中偏瘫患者用康复系统。The invention relates to the technical field of intelligent rehabilitation, in particular to a rehabilitation system for stroke hemiplegia patients.

背景技术Background technique

脑卒中又称脑血管意外(Cerebral Vascular Accident，CVA)，是一种因脑动脉系统病变引起的血管痉挛、闭塞或破裂，造成急性发展的脑局部循环障碍和以偏瘫为主的肢体功能障碍，包括缺血性卒中(Ischemic Stroke)和出血性卒中(Hemorrhagic Stroke)两类。脑卒中作为一类常见的神经系统疾病，因其发病率、死亡率、复发率和致残率均较高，已经成为严重威胁居民生命健康和生活质量的重大疾病。糖尿病是缺血性脑卒中的独立危险因素，长期高血糖增加中风风险，糖尿病患者中风发病率是正常人的四倍，高血糖通过多种途径损伤脑血管导致动脉粥样硬化，影响血管壁弹性和硬度，出现血管内膜斑块形成、狭窄、闭塞等病理改变，由于血脂异常、高血压、动脉粥样硬化、血液黏稠度增高等并发症导致心脏、大脑及全身组织受损，发生缺血性或出血性症状。Stroke, also known as cerebrovascular accident (Cerebral Vascular Accident, CVA), is a kind of vasospasm, occlusion or rupture caused by cerebral arterial system disease, resulting in acute development of local brain circulation disorder and limb dysfunction mainly hemiplegia. Including ischemic stroke (Ischemic Stroke) and hemorrhagic stroke (Hemorrhagic Stroke) two categories. As a common neurological disease, stroke has become a major disease that seriously threatens the life, health and quality of life of residents due to its high morbidity, mortality, recurrence rate and disability rate. Diabetes is an independent risk factor for ischemic stroke. Long-term high blood sugar increases the risk of stroke. The incidence of stroke in diabetic patients is four times that of normal people. High blood sugar damages cerebral blood vessels through various ways, leading to atherosclerosis and affecting the elasticity of blood vessel walls. Pathological changes such as intimal plaque formation, stenosis, and occlusion appear, and complications such as dyslipidemia, hypertension, atherosclerosis, and increased blood viscosity lead to damage to the heart, brain, and systemic tissues, and ischemia occurs Sexual or hemorrhagic symptoms.

脑卒中会造成上运动神经元的损伤，常常导致中枢性的瘫痪，造成肢体的功能障碍，包括阳性症状与阴性症状。其中的阴性症状有以下几个方面：肌力的下降、运动控制能力的降低及肢体协调性的下降等；而阳性症状包括反射亢进、痉挛程度的增加等。此外还有一些特殊的运动协调障碍模式：如共同收缩、异常协同运动等。而脑中风偏瘫后的异常协同运动模式已经成为了上肢运动功能障碍的典型特征，这些异常的运动模式阻碍了正常运动模式的完成，对患者的日常生活活动性能造成了非常严重的影响。据全国第三次国民死因调查统计，国内第一大死亡原因是脑卒中，幸存者75％以上留有不同程度的后遗症，其中40％为重度残疾，包括肢体、语言、认知等方面的障碍，常见且对患者影响最大的是运动功能障碍，尤以偏瘫最常见。70％以上的患者不同程度的丧失生活及工作能力，严重影响了患者的日常生活活动(Activitiesof Daily Living，ADL)能力。据相关研究显示，脑卒中患者在急性治疗期、康复治疗阶段、返回社区生活中有过跌倒的比率分别为14％～64.5％、24％～47％和37.5％～73％，跌倒已成为脑卒中患者的一种发生率极高的主要并发症。Stroke can cause damage to upper motor neurons, often leading to central paralysis and limb dysfunction, including positive and negative symptoms. Among them, negative symptoms include the following aspects: decreased muscle strength, decreased motor control ability, and decreased coordination of limbs, etc.; while positive symptoms include hyperreflexia and increased spasticity. In addition, there are some special patterns of motor coordination disorders: such as co-contraction, abnormal coordinated movement, etc. The abnormal cooperative movement pattern after stroke hemiplegia has become a typical feature of upper limb motor dysfunction. These abnormal movement patterns hinder the completion of normal movement patterns and have a very serious impact on the performance of daily life activities of patients. According to the statistics of the third national national cause of death survey, stroke is the leading cause of death in China, and more than 75% of survivors have sequelae of varying degrees, of which 40% are severe disabilities, including physical, language, cognitive and other obstacles , common and most affected by patients is motor dysfunction, especially the most common hemiplegia. More than 70% of the patients lost the ability to live and work to varying degrees, seriously affecting the patients' activities of daily living (Activities of Daily Living, ADL) ability. According to relevant studies, the rates of stroke patients who have fallen during the acute treatment period, rehabilitation treatment period, and return to community life are 14%-64.5%, 24%-47%, and 37.5%-73%, respectively. A major complication with high incidence in stroke patients.

跌倒是指出现突然发生的、不自主的、非故意的体位改变而倒在地上或更低的平面上。跌倒会造成脑部损伤、软组织损伤、骨折和脱臼甚至死亡等伤害，尤其对脑卒中患者，跌倒及其后果会给患者及家属造成巨大的身心伤害，严重影响患者及家属的生活质量，对跌倒的恐惧造成部分患者减少活动或其家属限制患者活动，结果导致患者自理能力下降。同时跌倒也导致患者住院费用及住院时间增加，给家庭和社会带来巨大负担。为了有效预防脑卒中患者跌倒的发生，目前常用的方法为采用量表对患者进行评估，筛选易跌倒高危人群，采取保证患者居住的环境安全、加强患者及家属防跌倒知识健康宣教、床头挂警示牌等统一措施预防患者跌倒，但以上措施缺乏针对性，目前尚无现有技术提出针对脑卒中偏瘫患者进行离床跌倒风险预防及干预的护理装置。因此，到目前为止，跌倒尤其是针对脑卒中偏瘫患者的离床跌倒风险仍然是困扰医护人员的主要问题之一。A fall is defined as a sudden, involuntary, involuntary change in position resulting in falling to the ground or a lower level. Falls can cause brain injuries, soft tissue injuries, fractures, dislocations, and even death. Especially for stroke patients, falls and their consequences can cause huge physical and mental harm to patients and their families, seriously affecting the quality of life of patients and their families. Fear caused some patients to reduce their activities or their family members to restrict their activities, resulting in a decline in the patient's ability to take care of themselves. At the same time, falls also lead to an increase in hospitalization costs and hospitalization time of patients, which brings a huge burden to families and society. In order to effectively prevent the occurrence of falls in stroke patients, the current commonly used methods are to use scales to evaluate patients, to screen high-risk groups for falls, to ensure the safety of the living environment of patients, to strengthen the health education of patients and their families on the prevention of falls, and to hang hanging on the bedside. Unified measures such as warning signs prevent patients from falling, but the above measures lack pertinence. At present, there is no existing technology that proposes a nursing device for preventing and intervening in the risk of falling out of bed for hemiplegic patients after stroke. Therefore, so far, the risk of falls, especially for hemiplegic patients after stroke, is still one of the main problems that plague medical staff.

又如公开日为2020年2月28日的公开号为CN 110853299A的专利文献所提出的一种儿童防掉床和离床检测报警装置，在床的一侧设置床栏(1)，还包括安装在床头一侧的光电发射管LED 1(2)，安装在床头另一侧的光电接收管V1(3)，光电接收管V1用来接收光电发射管LED 1的发射信号，在床头的另一侧安装无线发射器(4)，与无线发射器对应的无线接收器安装在儿童身上，在床下安装红外传感器IRX(5)，还包括与光电发射管LED 1、光电接收管V1、无线发射器、红外传感器IRX连接的外围电路；其所设置的报警装置能够时刻对儿童的睡觉状态进行监控，当儿童不慎掉床或是离床时，能够发出警报。Another example is a kind of anti-falling and bed-leaving detection and alarm device for children proposed by the patent document whose publication number is CN 110853299A on February 28, 2020. A bed rail (1) is set on one side of the bed, and includes The photoelectric emission tube LED 1 (2) installed on one side of the head of the bed, and the photoelectric receiving tube V1 (3) installed on the other side of the bed. The photoelectric receiving tube V1 is used to receive the transmission signal of the photoelectric emission tube LED 1. The wireless transmitter (4) is installed on the other side of the head, and the wireless receiver corresponding to the wireless transmitter is installed on the child, and an infrared sensor IRX (5) is installed under the bed, which also includes a photoelectric emission tube LED 1 and a photoelectric receiving tube V1. , wireless transmitter, and peripheral circuit connected by infrared sensor IRX; the alarm device set up can monitor the child's sleeping state at all times, and can send an alarm when the child accidentally falls out of bed or leaves the bed.

针对上述专利文献所存在的预警性差的问题，如下现有技术提出了具有较好预警性的技术方案：In view of the problem of poor early warning in the above patent documents, the following prior art proposes a technical solution with better early warning:

例如授权公告日为2016年8月31日的授权公告号为CN 103824418B的专利文献所提出的一种离床监护的报警系统，该离床监护的报警系统包括两个压电薄膜传感器、处理器以及报警器。两个压电薄膜传感器沿床的长边延伸方向依次铺设在床上，并同步连续采集来自床上的压力信号。处理器根据两个压力信号分别形成床上人体的两个周期性生理特征信号，并在两个周期性生理特征信号同步中断时，判断人体摔落离床，而在两个周期性生理特征信号前后中断时，判断人体先是坐起再起身自行离床。报警器在摔落离床时发出报警提示。其报警系统能及时发现人体摔落离床，便于做出迅速的补救措施。该专利文献还涉及安装有该离床监护的报警系统的床、与该离床监护的报警系统配套使用的离床监护的报警装置及其报警方法。For example, the authorization announcement date is August 31, 2016, and the authorization announcement number is CN 103824418B. A kind of alarm system for bed monitoring is proposed. The alarm system for bed monitoring includes two piezoelectric film sensors, a processor and an alarm. Two piezoelectric film sensors are sequentially laid on the bed along the extension direction of the long side of the bed, and the pressure signals from the bed are collected synchronously and continuously. The processor forms two periodic physiological characteristic signals of the human body on the bed according to the two pressure signals, and judges that the human body has fallen off the bed when the two periodic physiological characteristic signals are synchronously interrupted. When interrupting, it is judged that the human body first sat up and then got up and left the bed by itself. The alarm sends out an alarm prompt when falling off the bed. Its alarm system can detect that the human body falls off the bed in time, so that it is convenient to make rapid remedial measures. The patent document also relates to a bed equipped with the alarm system for leaving the bed monitoring, an alarm device for leaving the bed monitoring used in conjunction with the alarm system for leaving the bed monitoring, and an alarm method thereof.

现有的如上述专利文献所提出的离床报警装置要实现离床报警的功能，必须是在被监护对象的行动能力非常好的基础上才能实现，因为其装置判断人体是否自行离床得先判断人体是否直立坐起身，从仰卧姿势直接转换为坐姿的过程对被监护对象的腹部力量要求非常大，该动作对于行动不便的例如脑卒中偏瘫患者此类人群而言是不可能完成的动作，因而上述装置无法适用于行动不便的例如脑卒中偏瘫患者此类人群的离床报警，只会增大误警率。The existing alarm device for leaving the bed as proposed in the above-mentioned patent documents must realize the function of alarming for leaving the bed only on the basis of the very good mobility of the monitored object, because the device must first judge whether the human body leaves the bed by itself. Judging whether the human body is sitting upright, the process of directly converting from a supine position to a sitting position requires a lot of abdominal strength of the subject to be monitored. This action is impossible for people with limited mobility, such as stroke hemiplegia patients. Thereby said device can't be applicable to the bed alarm of people with limited mobility such as stroke hemiplegia patients, which will only increase the false alarm rate.

又例如公开日为2019年5月17日的公开号为CN 109757928A的专利文献所提出的一种防摔智能婴儿床，至少包括婴儿床本体和与婴儿床本体固接的婴儿床床架，防摔智能婴儿床还包括婴儿翻越检测模块、若干个手部行为检测模块和若干个脚部行为检测模块。在至少一个特定事件发生之时，通过若干个脚部行为检测模块中的至少一个和若干个手部行为检测模块中的至少一个获取并记录该特定事件发生之时防摔智能婴儿床的压力变化信息，并且基于接收到的压力变化信息进行婴儿翻越预估分析并输出与之匹配的婴儿翻越预估结果和/或婴儿翻越风险等级至中央处理模块，中央处理模块基于接收到的婴儿翻越预估结果和/或婴儿翻越风险等级向由监护人操作的智能终端发出预警提示和/或通过声光提示模块发出第一声光信息。Another example is an anti-drop smart crib proposed by the patent document CN 109757928A with the publication date of May 17, 2019, which at least includes a crib body and a crib bed frame affixed to the crib body. The falling intelligent crib also includes a baby overturning detection module, several hand behavior detection modules and several foot behavior detection modules. When at least one specific event occurs, at least one of several foot behavior detection modules and at least one of several hand behavior detection modules acquire and record the pressure change of the anti-fall intelligent crib when the specific event occurs Information, and based on the received pressure change information, carry out the baby moving prediction analysis and output the matching baby moving prediction result and/or baby moving risk level to the central processing module, and the central processing module is based on the received baby moving prediction The result and/or the risk level of the baby jumping over will send an early warning prompt to the smart terminal operated by the guardian and/or send the first sound and light information through the sound and light prompt module.

而诸如上述专利文献所提出的离床报警装置，其利用用户手部、脚部分别与床体上设置的分区域的压力传感器之间进行交互的动作过程，能够提供较好的预警作用，但其面向的对象也只能局限于离床之前还需要翻越床架的婴幼儿，同样地无法适用于行动不便的注入高龄患者术后、膝关节或髋关节置换的患者、术后因贫血或比较虚弱的患者或是脑卒中偏瘫患者，其不听医护人员劝告，擅自下床，也不叫家属陪同，导致意外自行离床或是坠床事件的发生。And such as the bed-leaving alarm device proposed in the above-mentioned patent documents, it utilizes the action process of interaction between the user's hands and feet and the sub-regional pressure sensors provided on the bed body respectively, which can provide a better early warning effect, but Its oriented objects can only be limited to infants and young children who need to climb over the bed frame before leaving the bed. Similarly, it cannot be applied to elderly patients with limited mobility after surgery, patients with knee or hip replacement, and patients with anemia or comparison after surgery. Weak patients or stroke hemiplegia patients do not listen to the advice of medical staff, get out of bed without authorization, and do not ask their family members to accompany them, resulting in accidental accidents or falling out of bed.

针对上述现有技术文献虽然具有较好预警性但适用范围局限性太大的问题，现有技术提出了否弃行为监测范围有限的非接触式监测设备(诸如上述所列举的设置有多个传感器的床垫)，转而采用行为监测能力更好的佩戴式监测设备的技术方案，例如：In view of the problem that the above-mentioned prior art documents have good early warning but too limited scope of application, the prior art proposes a non-contact monitoring device with a limited range of behavior monitoring (such as the ones listed above that are provided with multiple sensors) mattresses), and switch to technical solutions for wearable monitoring devices with better behavior monitoring capabilities, such as:

公开日为2019年7月5日的公开号为CN 109966088A的专利文献所提出的一种临床预警系统，其包括电子标签、标签读取模块、病房路由终端、云平台、监护终端和护士站终端；电子标签，包括有设置于患者脚部的脚环，脚环内设有RFID电子标签；标签读取模块，设置于床体下方，包括有屏蔽罩，屏蔽罩上设有朝向床侧方的开口，屏蔽罩内设有用于对RFID电子标签进行无线读取的读取单元。与现有技术相比，该临床预警系统中在处于病床下方的标签读取模块读取到电子标签时，表示患者下床，由病房路由终端传输给云平台，云平台对信息进行处理，分别传输给陪护终端和护士站终端，这样实时监测脚环离床距离，并实时预警跌落风险，及时向陪护人员和护士站发出预警信息。A clinical early warning system proposed by the patent document with the publication number CN 109966088A on July 5, 2019, which includes electronic tags, tag reading modules, ward routing terminals, cloud platforms, monitoring terminals and nurse station terminals The electronic tag includes an ankle ring arranged on the patient's foot, and an RFID electronic tag is arranged in the ankle ring; the tag reading module is arranged under the bed body, and includes a shielding cover, and the shielding cover is provided with a shield facing the side of the bed There is an opening, and a reading unit for wirelessly reading the RFID electronic tag is arranged in the shielding case. Compared with the existing technology, in this clinical early warning system, when the tag reading module under the hospital bed reads the electronic tag, it means that the patient has got out of bed, and the routing terminal in the ward transmits it to the cloud platform, and the cloud platform processes the information. It is transmitted to the escort terminal and the nurse station terminal, so as to monitor the distance between the foot ring and the bed in real time, and give a real-time warning of the risk of falling, and send an early warning message to the escort and nurse station in time.

此类技术方案未考虑实际应用时，被监护对象可能仅仅是将脚部伸出床体外沿就引起了该装置的警报，然而实际上被监护对象并完全没有下床也更没有要自行下床的趋势。When this kind of technical solution does not consider the practical application, the monitored object may only cause the alarm of the device by extending the foot out of the bed, but in fact the monitored object does not get out of bed at all, let alone get out of bed by itself the trend of.

此外，例如中国专利CN114948594A公开了机械联动同步式术后患者训练护理仪，包括床体，床体内部右侧前后两端转接的下肢穿戴组件，可对患者的下肢进行康复训练，床体内部左侧前后两端转接的上肢穿戴组件，可对患者的上肢进行康复训练，床体底部滑动设置的驱动组件，可控制上肢穿戴组件以及下肢穿戴组件同步运动。该专利对于下肢术后的患者而言，通过患者上肢的主动驱动力，被动式的控制患者下肢的运动训练，对于上肢术后的患者而言，通过患者下肢的主动驱动力，被动式的控制患者上肢的运动训练，进而实现了患者四肢的同步运动训练。该专利通过机械联动式的设计，使得患者的四肢处于同步且反复式的运动操作，不仅提高了本装置的使用效果，还提高了患者肢体的康复训练效果。In addition, for example, the Chinese patent CN114948594A discloses a mechanical linkage synchronous postoperative patient training and nursing device, including a bed body, and a lower limb wearing component connected to the front and rear ends on the right side of the bed body, which can perform rehabilitation training on the patient's lower limbs. The upper limb wearable component connected to the front and rear ends of the left side can carry out rehabilitation training for the patient’s upper limbs, and the driving component slidingly installed at the bottom of the bed can control the synchronous movement of the upper limb wearable component and the lower limb wearable component. For patients after lower limb surgery, the patent passively controls the movement training of the patient's lower limbs through the active driving force of the patient's upper limbs; for patients after upper limb surgery, passively controls the patient's upper limbs through the active driving force of the patient's lower limbs Movement training, and then realize the synchronous movement training of the patient's limbs. The patent uses a mechanical linkage design to make the patient's limbs in synchronous and repetitive motion operations, which not only improves the use effect of the device, but also improves the rehabilitation training effect of the patient's limbs.

中国专利CN115300266A涉及一种腿部康复病床，包括带有支撑腿的床板，床板上沿床板的长度方向开设有通槽，通槽内转动连接有第一转轴，第一转轴的长度方向与床板的宽度方向平行，第一转轴的侧壁上固定套设有供腿放置且带有绑绳的转动板；转动板远离第一转轴的一端上设有供脚踩住的踩板；第一转轴上还固连有供手部抓持的把手。该专利使病人可以自主地进行腿部的康复训练，无需人工进行干预，大大节省了人力，同时还有效提高了病人在康复训练中的参与度和积极性，提升了康复训练的效果。Chinese patent CN115300266A relates to a leg rehabilitation bed, including a bed board with supporting legs, a through groove is opened on the bed board along the length direction of the bed board, and a first rotating shaft is rotatably connected in the through groove, and the length direction of the first rotating shaft is consistent with the length direction of the bed board. The width direction is parallel, and the side wall of the first rotating shaft is fixedly provided with a rotating plate for placing the legs and having a rope; There is also a handle for grasping by hand. This patent enables patients to independently perform leg rehabilitation training without manual intervention, which greatly saves manpower, and at the same time effectively improves the participation and enthusiasm of patients in rehabilitation training and improves the effect of rehabilitation training.

但是上述现有技术中未针对如何让患者明确康复训练目标，同时增强患者佩戴穿戴式设备的主观意愿，不会因反感其监测目的而取下的问题提出优化方案，因此需要一种能够在康复训练时间段和非康复训练时间段起到离床预警监测作用的脑卒中偏瘫患者用康复系统。However, in the above-mentioned prior art, there is no optimization plan for how to let the patient clarify the rehabilitation training goal, and at the same time enhance the patient's subjective willingness to wear the wearable device, and will not take it off because of disgust for monitoring purposes. The rehabilitation system is used for hemiplegic stroke patients who play the role of early warning and monitoring of leaving the bed during the training period and non-rehabilitation training period.

此外，一方面由于申请人所理解的本领域技术人员与审查部门必然有所差异；另一方面由于发明人做出本发明时研究了大量文献和专利，但篇幅所限并未详细罗列所有的细节与内容，然而这绝非本发明不具备这些现有技术的特征，相反本发明已经具备现有技术的所有特征，而且申请人保留依据审查指南相关规定随时在背景技术中增加相关现有技术之权利。In addition, on the one hand, the technical personnel in the field understood by the applicant are necessarily different from the examination department; Details and content, however, it is by no means that the present invention does not possess the characteristics of these prior art, on the contrary, the present invention already possesses all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background art at any time according to the relevant provisions of the Examination Guidelines rights.

本发明还提出了一种脑卒中偏瘫患者用离床预警系统，尤其是指适用于同一侧上下肢均存在运动功能障碍的且区别有患侧上下肢与健侧上下肢的被监护对象的离床预警系统。The present invention also proposes a bed-leaving early warning system for stroke hemiplegia patients, especially suitable for the bed-leaving warning system for the monitored object whose upper and lower limbs on the same side have motor dysfunction and distinguishes the upper and lower limbs of the affected side from the upper and lower limbs of the healthy side. bed warning system.

本发明的离床预警系统是针对现有技术中为实现离床报警功能所提出的离床报警装置所存在的不足而提出的，现有技术之不足在于：针对具有高发生率及高危害性的跌倒问题尤其是针对脑卒中单侧偏瘫患者的自行离床跌倒问题，现有技术中为实现离床报警功能所提出的离床报警装置大致可分为基于非接触式监测设备或佩戴式监测设备的解决方案。其一，就现有技术中如授权公告号为CN103824418B的专利文献所提出的基于非接触式监测设备如智能床垫所提出的解决方案而言，此类解决方案对人体是否自行离床的判断，等同于判断人体是否直立坐起身，实际上，直立坐起身的动作需从仰躺姿势直接转换为坐姿，该过程对被监护对象的腹部力量要求非常大。因此此类解决方案中离床报警功能的实现，是建立在被监护对象的行动能力非常好的基础上的，对于行动不便的例如脑卒中偏瘫患者此类人群而言，该动作是难度非常大甚至不可能完成的。因而此类解决方案无法适用于行动不便的例如脑卒中偏瘫患者此类人群的离床报警，只会增大误警率。其二，针对基于佩戴式监测设备的如公开号为CN109966088A的专利文献所提出的基于内设有RFID电子标签的脚环的解决方案，此类解决方案中离床报警功能的实现，是通过监测脚环是否移动出床体之外的区域来实现的，判定其只要脚环移动出床体即为离床并进行报警，然而，此类解决方案未考虑实际应用时，被监护对象可能仅仅是将脚部伸出床体外沿，而并非已经离床也更没有要自行离床的趋势，但该情况下仍会引起该装置的警报，误警率高，反而增大护理人员工作负担，同时由于其在活动度较高的脚部设置脚环，不仅佩戴时不适感强烈，而且监测目的非常明显，容易引起患者反感而自行摘除，无法监测到其是否擅自离床。尤其是针对如脑卒中单侧偏瘫患者的被监护对象，其患侧上下肢均存在运动功能障碍且肢体感觉受损严重，患者往往需要利用健侧的支撑作用才能移动患侧，对人工辅助护理的依赖程度以及行动受限的反感程度都非常高。The bed-leaving warning system of the present invention is proposed in view of the shortcomings of the bed-leaving alarm device proposed in the prior art for realizing the bed-leaving alarm function. Especially for the fall problem of unilateral hemiplegia patients with stroke, the bed alarm devices proposed in the prior art to realize the alarm function of getting out of bed can be roughly divided into non-contact monitoring equipment or wearable monitoring devices. device solutions. First, in terms of solutions based on non-contact monitoring equipment such as smart mattresses proposed in the prior art such as the patent literature with the authorized announcement number CN103824418B, the judgment of whether the human body leaves the bed by itself , which is equivalent to judging whether the human body sits upright. In fact, the action of sitting upright needs to be directly converted from a supine position to a sitting position. This process requires a lot of abdominal strength of the subject being monitored. Therefore, the realization of the bed alarm function in this type of solution is based on the very good mobility of the monitored object. For people with limited mobility, such as stroke hemiplegia patients, this action is very difficult. It's not even possible to complete. Thereby this kind of solution can't be applicable to the bed alarm of people with limited mobility such as stroke hemiplegia patients, which will only increase the false alarm rate. Second, for the solution based on the foot ring with the RFID electronic tag built in the patent document based on the wearable monitoring device such as the publication number CN109966088A, the realization of the alarm function of leaving the bed in this type of solution is achieved by monitoring It is realized whether the foot ring moves out of the bed, and it is judged that as long as the foot ring moves out of the bed, it is out of bed and an alarm is given. However, when this kind of solution does not consider the actual application, the monitored object may only Stretching the feet out of the bed, not leaving the bed and not having the tendency to leave the bed by itself, but in this case it will still cause the alarm of the device, the false alarm rate is high, and it will increase the workload of the nursing staff. Because it is equipped with foot rings on the feet with high mobility, not only the discomfort is strong when worn, but also the monitoring purpose is very obvious, which is easy to cause the patient's disgust and remove it by himself, and it is impossible to monitor whether he leaves the bed without authorization. Especially for the monitored objects such as patients with unilateral hemiplegia after stroke, the upper and lower limbs of the affected side have motor dysfunction and the limb sensation is severely impaired. Patients often need to use the support of the healthy side to move the affected side. The degree of dependence and aversion to restricted mobility are very high.

以此，针对上述现有技术中离床报警装置之不足，本发明提出了脑卒中偏瘫患者用离床预警系统，所述系统包括：采集模块，其用于获取由仅佩戴于被监护对象的患侧上下肢的穿戴式设备所采集到的行为数据；风控等级划分模块，其用于根据被监护对象历史风控数据来确定与之对应的风控等级，其中，所述被监护对象尤其是指同一侧上下肢均存在运动功能障碍的且区别有患侧上下肢与健侧上下肢的人群，所述系统还包括：预警信息处理器，其被配置为至少基于由采集模块从佩戴于被监护对象的患侧上下肢的至少一个穿戴式设备所采集到的行为数据中所提取到的至少一个运动特征值之间的与由监护人员所操作的至少一个移动数字设备所确定的运动功能障碍评估结果所对应的阶段属性关联规则以及预设的风控等级来判断其行为数据是否触发预警。优选地，在触发预警时将预警信息传递至周边的由监护人员所携带的至少一个移动数字设备。Therefore, aiming at the deficiency of the bed-leaving alarm device in the above-mentioned prior art, the present invention proposes a bed-leaving early warning system for hemiplegic patients after stroke. The system includes: a collection module, which is used to obtain the The behavior data collected by the wearable device of the upper and lower limbs of the affected side; the risk control level division module, which is used to determine the corresponding risk control level according to the historical risk control data of the monitored object, wherein the monitored object is especially Refers to people who have motor dysfunction in the upper and lower limbs on the same side and distinguish between the upper and lower limbs on the affected side and the upper and lower limbs on the unaffected side. The system also includes: an early warning information processor configured to at least be based on The difference between at least one motion feature value extracted from the behavior data collected by at least one wearable device of the affected upper and lower limbs of the monitored object and the motion function determined by at least one mobile digital device operated by the guardian The phase attribute association rules corresponding to the obstacle assessment results and the preset risk control level are used to determine whether the behavior data triggers an early warning. Preferably, when the warning is triggered, the warning information is transmitted to at least one mobile digital device carried by the guardian.

本申请通过设置仅穿戴于存在运动功能障碍的一侧上下肢的穿戴式设备，由于患侧肢体感觉受损严重，感知能力低，对穿戴式设备的接受度更好，并且保留了健侧不受限的良好活动能力，同时患侧肢体活动程度较低，大大地降低了需要处理的数据量。基于此，本发明中预警信息处理器是在区别于不同患者的不同风险控制等级以及不同偏瘫单侧的运动功能障碍程度的基础上，限定出的用于指示预警危险度且彼此预警危险度不同的若干监测模式，从而预警信息处理器能够基于患者当前的行为数据与预设若干监测模式相比对，基于比对结果以及预设的患侧上下肢之间的阶段属性关联规则来判断是否需要预警，提高了在危险发生前就通知监护人员为被监护对象提供及时的看护或辅助的预警时效性。This application sets up wearable devices that are only worn on the upper and lower extremities on one side with motor dysfunction. Due to the severe sensory impairment of the limbs on the affected side and low perception ability, the acceptance of wearable devices is better, and the unaffected side is retained. The limited good mobility, combined with the low degree of physical activity on the affected side, greatly reduces the amount of data that needs to be processed. Based on this, the early warning information processor in the present invention is based on the different risk control levels of different patients and the degree of motor dysfunction of different hemiplegic unilateral sides, and is defined to indicate the risk of early warning and the risk of early warning is different from each other. Several monitoring modes, so that the early warning information processor can compare the current behavior data of the patient with the preset monitoring modes, and judge whether it is necessary based on the comparison results and the preset phase attribute association rules between the upper and lower limbs of the affected side.

摆放姿势：也称体位摆放姿势或良肢位，是指为防止或对抗痉挛姿势的出现，保持肩关节及早期诱发分离运动而设计的一种治疗体位。该点即为脑卒中偏瘫患者的卧床体位摆放的特殊性要求。脑卒中偏瘫患者的典型姿势表现为上肢的肩下沉后缩，肘关节屈曲，前臂旋前，腕关节掌屈，手指屈曲；下肢的外旋，髋膝关节伸直，足下垂内翻。早期注意并保持床上的正确体位，有助于预防或减轻上述痉挛姿势的出现和加重。如图2所示，通常选用以下体位：患侧卧位、健侧卧位、仰卧位。″患侧卧位″即患侧在下，健侧在上。头部用枕头舒适的支撑，患侧上肢前伸，使肩部向前，确保肩胛骨的内缘平靠于胸壁。上臂前伸以避免肩关节受压和后缩。肘关节伸展，前臂旋后，手指张开，掌心向上。健侧上肢不能放在身前，因会带动整个躯干向前而引起肩胛骨后缩。患侧下肢在后，患髋关节微后伸，膝关节略屈曲，足底蹬支撑物。″健侧卧位″即健侧在下，患侧在上，头部枕头不宜过高。患侧上肢下垫一枕头，肩前屈90°～130°，肘和腕伸展，前臂旋前，腕关节背伸，患侧骨盆旋前，髋、膝关节呈自然半屈曲位，置于枕上；患足与小腿尽量保持垂直位，注意足不能内翻悬于枕头边缘；身后可放置枕头支撑，有利于身体放松。健侧下肢平放在床上，轻度伸髋，稍屈膝。″仰卧位″即头下置一枕头，但不宜过高，面部朝向患侧；患侧肩部垫一比躯干略高的枕头，将伸展的上肢置于枕上，防止肩胛骨后缩；前臂旋后，手掌心向上，手指伸展、张开；在患侧臀部及大腿下垫枕，以防止患侧骨盆后缩。Positioning posture: also known as posture positioning or good limb position, it refers to a therapeutic position designed to prevent or combat the appearance of spastic postures, maintain shoulder joints and induce early separation movements. This point is the specific requirement for bed resting position of stroke hemiplegia patients. The typical posture of stroke patients with hemiplegia is as follows: shoulder sinking and retraction of the upper limbs, elbow flexion, forearm pronation, wrist flexion, and fingers flexion; lower limbs external rotation, hip and knee joint extension, foot drop and varus. Early attention and maintaining the correct posture on the bed can help prevent or reduce the occurrence and aggravation of the above-mentioned spastic postures. As shown in Figure 2, the following positions are usually used: lying on the affected side, lying on the healthy side, and supine. "Ipsilateral lying position" means that the affected side is down and the healthy side is up. With the head comfortably supported by a pillow, the affected upper limb is extended forward, bringing the shoulder forward and ensuring that the inner edge of the scapula rests flat against the chest wall. Extend the upper arm forward to avoid compression and retraction of the shoulder joint. Elbow extended, forearm supinated, fingers splayed, palms up. The upper limb on the healthy side cannot be placed in front of the body, because it will drive the entire trunk forward and cause the scapula to retract. The lower limb of the affected side is behind, the affected hip joint is slightly extended, the knee joint is slightly flexed, and the sole of the foot is pushed on the support. The "healthy side lying position" means that the healthy side is down and the affected side is up, and the head pillow should not be too high. Put a pillow under the upper limb of the affected side, flex the shoulder 90°-130°, extend the elbow and wrist, pronate the forearm, dorsiflex the wrist joint, pronate the pelvis on the affected side, and place the hip and knee joints in a natural semi-flexed position, and place them on the pillow ; Keep the affected foot and calf in a vertical position as much as possible, and pay attention to the foot not turning inward and hanging over the edge of the pillow; a pillow can be placed behind the back for support, which is conducive to body relaxation. Put the lower limb of the healthy side flat on the bed, slightly extend the hip, and slightly bend the knee. "Supine position" means placing a pillow under the head, but it should not be too high, with the face facing the affected side; a pillow slightly higher than the trunk is placed on the shoulder of the affected side, and the stretched upper limbs are placed on the pillow to prevent the retraction of the scapula; the forearm is supinated , with palms facing upwards, fingers stretched and opened; a pillow is placed under the buttocks and thighs of the affected side to prevent the pelvic retraction of the affected side.

运动特征变化趋势：在该摆放姿势下可能将出现的运动特征变化趋势，指的是在监护人员调整了被监护对象的姿势至合适的摆放姿势后，被监护对象在无监护的情况下可能出现的行为。其包括危险系数极低的肢体小幅度抬放翻转等且被监护对象的摆放姿势不改变的第一模式、危险系数中等的尝试翻身或是尝试起身且被监护对象的独立性差的第二模式、危险系数较大的尝试翻身或是尝试起身且被监护对象的独立性较好的第三模式、以及危险系数较大的肢体小幅度抬放翻转等且被监护对象的摆放姿势发生改变的第四模式。区别于不同的体位摆放姿势，各体位摆放姿势分别对应有预定义的第一模式、第二模式、第三模式和第四模式。Change trend of movement characteristics: The change trend of movement characteristics that may appear in this posture refers to that after the guardian adjusts the posture of the monitored object to a suitable posture, the monitored object will not be monitored without supervision. possible behavior. It includes the first mode in which the limbs are lifted and turned slightly with a very low risk factor and the posture of the monitored object does not change, and the second mode in which the risk factor is medium and the object is tried to turn over or try to get up and the independence of the monitored object is poor. , the third mode of trying to turn over or trying to stand up with a high risk factor and the independence of the warded object is better, and the small lifting and turning of the limbs with a high risk factor and the posture of the warded object changes Fourth mode. Different from different body postures, each body posture corresponds to a predefined first mode, second mode, third mode and fourth mode.

阶段属性关联规则：阶段属性关联规则与由监护人员所操作的至少一个移动数字设备7所确定的运动功能障碍评估结果相对应。这里所提及的阶段属性关联规则指的是根据由用户当前的运动功能障碍评估结果所确定的运动功能障碍程度，区别于患者在当前阶段下所伴有的运动功能障碍的程度，来确定的第一运动特征值所对应的运动特征变化趋势与第二运动特征值所对应的运动特征变化趋势。这里所提及的运动特征变化趋势，主要是指保持在某一摆放姿势下的被监护对象在无监护的情况下可能出现的行为，其主要用于区别第一模式、第二模式、第三模式和第四模式之间的界限/触发阈值。进一步优选地，本发明中所提及的“预警信息处理器4基于预设的风控等级以及第一运动特征值与第二运动特征值之间的与由监护人员所操作的至少一个移动数字设备7所确定的运动功能障碍评估结果所对应的阶段属性关联规则来判断其行为数据是否触发预警”中，阶段属性关联规则与风控等级只是用于预警信息处理器4判断行为数据是否触发预警的部分待处理数据。Phase attribute association rules: phase attribute association rules correspond to motor dysfunction assessment results determined by at least one mobiledigital device 7 operated by the guardian. The stage attribute association rule mentioned here refers to the degree of motor dysfunction determined by the user's current motor dysfunction evaluation results, which is different from the degree of motor dysfunction accompanied by the patient at the current stage. The motion feature change trend corresponding to the first motion feature value and the motion feature change trend corresponding to the second motion feature value. The changing trend of motion characteristics mentioned here mainly refers to the possible behaviors of the subject under supervision in a certain posture without supervision. It is mainly used to distinguish the first mode, the second mode, and the first mode. Demarcation/Trigger Threshold between Tri-Mode and Quad-Mode. Further preferably, the "earlywarning information processor 4" mentioned in the present invention is based on the preset risk control level and at least one movement number operated by the guardian between the first motion characteristic value and the second motion characteristic value. The stage attribute association rule corresponding to the motor dysfunction evaluation result determined by thedevice 7 is used to determine whether the behavior data triggers an early warning. In ", the stage attribute association rule and risk control level are only used for the earlywarning information processor 4 to judge whether the behavior data triggers an early warning. Part of the pending data.

针对阶段属性关联规则如下举例说明：在由监护人员所操作的至少一个移动数字设备7所确定的运动功能障碍评估结果为被监护对象的独立性较差时，确定与该情况下所对应的上肢预设运动幅度(上肢运动幅度触发阈值)、上肢预设挪动幅度(上肢挪动幅度触发阈值)、下肢预设运动幅度(下肢运动幅度触发阈值)以及下肢预设挪动幅度(下肢挪动幅度触发阈值)，以及基于确定的上述幅度/触发阈值，可以区别出第一模式、第二模式、第三模式和第四模式之间的界限，并且能够通过整体地调高或调低四个模式的上述幅度/触发阈值，可以使得该系统在离床预警模式与康复指导模式之间转换。区别于离床预警模式与康复指导模式下所对应的提醒方式，离床预警模式可以是电话铃声式持续地响铃且必须由医护人员手动才能关掉，康复指导模式可以是短信式简短地提示音而只是起到提示医护人员与被监护对象的作用即可。The phase attribute association rule is illustrated as follows: when the motor dysfunction evaluation result determined by at least one mobiledigital device 7 operated by the guardian is that the independence of the monitored object is poor, determine the upper limb corresponding to this situation Preset movement range (trigger threshold of upper limb movement range), upper limb preset movement range (upper limb movement range trigger threshold), lower body preset movement range (lower limb movement range trigger threshold) and lower limb preset movement range (lower limb movement range trigger threshold) , and based on the above-mentioned amplitude/trigger threshold determined, it is possible to distinguish the boundaries between the first mode, the second mode, the third mode, and the fourth mode, and it is possible to increase or decrease the above-mentioned amplitude of the four modes as a whole /Trigger threshold, which can make the system switch between the bed-leaving warning mode and the rehabilitation guidance mode. Different from the corresponding reminders in the bed-leaving warning mode and the rehabilitation guidance mode, the bed-leaving warning mode can be a phone ringing continuously and must be turned off manually by the medical staff, and the rehabilitation guidance mode can be a brief reminder in the form of a text message The sound only plays the role of reminding the medical staff and the objects under guardianship.

为明确运动特征变化趋势与体位摆放姿势之间的相关性，针对运动特征变化趋势进一步举例说明：当医护人员辅助患者调整至呈健侧卧位的体位摆放姿势时(即图2中的最后一个示意图，该示意图中患者侧卧且其患侧位于健侧上方)，由于床垫8的右侧设置有枕头且此时患侧位于床垫8右侧，即在无监护的情况下，患者想要下床，需利用健侧支撑，先将患侧朝向床垫8的左侧翻转，翻转至仰卧姿势再继续使用健侧来起身。患者无法在无监护的情况下自行朝向床垫右侧翻转。该过程中，患者需要先将放置在枕头上的患侧上肢收回，收回至患侧腰附近，同时利用健侧的力量逐渐将患侧下肢翻转至床垫左侧来。该过程中，由于患者在健侧卧位上，其健侧较为靠近床垫8的左侧边沿，即若患者朝向床垫8的左侧翻身，很有可能直接翻下床垫8或是出于非常靠近床边沿的危险位置上。该过程中，患者在健侧卧位上，也可能仅仅只是想要调整患肢的位置，来缓解可能出现的由长时间压迫引起的血液循环不畅，即有可能利用健侧来上下活动患侧上肢或小幅度挪动患侧下肢。In order to clarify the correlation between the change trend of motion characteristics and body posture, an example is given to further illustrate the change trend of motion characteristics: when the medical staff assists the patient to adjust to the position and posture of the uninjured side (that is, in Figure 2 The last schematic diagram, in this schematic diagram, the patient is lying on his side and its affected side is above the healthy side), since the right side of themattress 8 is provided with a pillow and the affected side is positioned at the right side of themattress 8, that is, without monitoring, If the patient wants to get out of bed, he needs to use the healthy side to support, first turn the affected side towards the left side of themattress 8, turn over to the supine position and continue to use the healthy side to get up. The patient is unable to roll himself over towards the right side of the mattress without supervision. During this process, the patient needs to retract the upper limb of the affected side placed on the pillow to the waist of the affected side, and at the same time use the strength of the healthy side to gradually turn the lower limb of the affected side to the left side of the mattress. During this process, since the patient is lying on the healthy side, the healthy side is relatively close to the left edge of themattress 8, that is, if the patient turns over towards the left side of themattress 8, it is likely to directly turn over themattress 8 or go out. in a dangerous position very close to the edge of the bed. During this process, the patient may just want to adjust the position of the affected limb in the lying position on the healthy side to alleviate the possible poor blood circulation caused by long-term compression, that is, it is possible to use the healthy side to move the affected limb up and down. Move the upper limb on the side or move the lower limb on the affected side slightly.

通过上述对处于健侧卧位的体位摆放姿势下的患者在无监护的情况下可能出现的行为的分析，以下对该体位摆放姿势所对应的第一模式、第二模式、第三模式和第四模式分别进行预设：若佩戴于患侧上肢的穿戴式设备1已采集到满足上肢预设运动幅度的行为数据，则在监测到患侧下肢的穿戴式设备1所采集到的行为数据满足下肢预设运动幅度、并且监测到患者由侧躺转换为仰躺或是由仰躺转换为侧躺时，确定当前患者情况为肢体小幅度抬放翻转等且被监护对象的摆放姿势发生改变的危险系数较大的第四模式。Based on the above analysis of the possible behaviors of patients in the lying position on the healthy side without supervision, the first mode, the second mode, and the third mode corresponding to the position are as follows and the fourth mode are respectively preset: if the wearable device 1 worn on the upper limb of the affected side has collected behavior data that meets the preset range of movement of the upper limb, then when the behavior data collected by the wearable device 1 of the lower limb of the affected side is monitored When the data meets the preset range of motion of the lower limbs, and it is monitored that the patient changes from lying on the side to lying on the back or from lying on the back to lying on the side, it is determined that the current patient's condition is a slight lifting and turning of the limbs and the posture of the monitored object The fourth mode with a higher risk factor for changes.

若佩戴于患侧上肢的穿戴式设备1已采集到满足上肢预设运动幅度的行为数据，并且被监护对象的独立性较好，则在监测到患侧下肢的穿戴式设备1所采集到的行为数据满足下肢预设运动幅度时，或是在监测到床垫8右侧上压力分布逐渐减少且左侧上压力分布逐渐增加时，由于被监护对象的独立性较好，翻身难度或起身难度不大，因而危险系数较大，确定其为第三模式。If the wearable device 1 worn on the upper limb of the affected side has collected behavioral data that meets the preset range of movement of the upper limb, and the independence of the monitored object is good, then the wearable device 1 that monitors the lower limb of the affected side When the behavioral data meets the preset range of motion of the lower limbs, or when the pressure distribution on the right side of themattress 8 gradually decreases and the pressure distribution on the left side gradually increases, due to the independence of the monitored object, it is difficult to turn over or get up. It is not large, so the risk factor is relatively large, so it is determined to be the third mode.

若佩戴于患侧上肢的穿戴式设备1已采集到满足上肢预设运动幅度的行为数据，并且被监护对象的独立性较差，则在监测到患侧下肢的穿戴式设备1所采集到的行为数据满足下肢预设运动幅度时，或是在监测到床垫8右侧上压力分布逐渐减少且左侧上压力分布逐渐增加时，患者通常是在尝试翻身或尝试起身，但由于被监护对象的独立性较差，翻身难度高，因而危险系数为中等，确定其为第二模式。If the wearable device 1 worn on the upper limb of the affected side has collected behavior data that meets the preset range of movement of the upper limb, and the independence of the monitored object is poor, then the wearable device 1 collected by the lower limb of the affected side When the behavioral data meets the preset range of motion of the lower limbs, or when the pressure distribution on the right side of themattress 8 gradually decreases and the pressure distribution on the left side gradually increases, the patient is usually trying to turn over or get up, but because the monitored object The independence of the patient is poor, and the difficulty of turning over is high, so the risk factor is medium, so it is determined to be the second mode.

在佩戴于患侧上肢的穿戴式设备1采集到满足上肢预设挪动幅度的行为数据、或是在监测到患侧下肢的穿戴式设备1所采集到的行为数据满足下肢预设挪动幅度，并且患者姿势未变化时，患者可能只是需要小幅度调整当前姿势而危险系数较低，确定其为第一模式。The behavior data collected by the wearable device 1 worn on the upper limb of the affected side meets the preset movement range of the upper limb, or the behavior data collected by the wearable device 1 that monitors the lower limb of the affected side meets the preset movement range of the lower limb, and When the patient's posture does not change, the patient may only need to slightly adjust the current posture and the risk factor is low, so it is determined to be the first mode.

针对“已接受过体位变化指导的被监护对象的运动特征变化趋势以及针对尚未接受过体位变化指导的被监护对象的运动特征变化趋势”：这里所指的体位变化指导主要是指在被监护对象已经住院一段时间，经由监护对象教导其正确合适的翻身或起身姿势。相对地，未接受过体位变化指导主要是指被监护对象刚住院或住院时间不长，尚未进行翻身或起身姿势指导。以此区别出的两种运动特征变化趋势，能够区别出当前被监护对象在脱离监护的情况下更可能出现的动作或行为，能够有效地提高数据比对处理的速度，进一步地提高了对被监护对象的监护准确性以及有效性。Aiming at "the changing trend of the movement characteristics of the monitored objects who have received the body position change guidance and the movement characteristics change trend of the monitored objects who have not received the body position change guidance": the body position change guidance referred to here mainly refers to the movement characteristics of the monitored objects After being hospitalized for a period of time, the subject taught him the correct and appropriate turning or standing posture. In contrast, those who have not received body position change guidance mainly refer to that the ward has just been hospitalized or has not been hospitalized for a long time, and has not yet been turned or stood up posture guidance. The two kinds of motion characteristic change trends distinguished in this way can distinguish the more likely actions or behaviors of the currently monitored object in the case of leaving the guardianship, which can effectively improve the speed of data comparison and processing, and further improve the accuracy of the monitored object. The accuracy and effectiveness of guardianship.

For example, theacquisition module 2 proposed in the patent document of the announcement number CN 104524760B with the authorized announcement date being August 29, 2017, which is equipped with a built-in smart bracelet that can acquire The three-axis gyro sensor with acceleration in three directions can capture the real-time acceleration value and vibration amplitude of the smart bracelet/affected limb in real time. Wherein, the built-in sensor in the wearable device 1 is not limited to the three-axis gyroscope sensor, any sensor capable of detecting the upward acceleration, forward acceleration and vibration amplitude of the basketball action is acceptable, such as the acceleration of gravity. The three-axis gyro sensor can simultaneously measure the position, movement trajectory and acceleration in six directions. The wearable device 1 has a built-in setting module, which is used to preset the position, movement track, and acceleration interval/amplitude captured by the sensor corresponding to body movements such as lifting, turning, and putting down.

该系统包括用于采集被监护对象的行为数据的采集模块2、用于确定风控等级的风控等级划分模块3、用于判断触发预警的预警信息处理器4、用于确定当前摆放姿势的摆放姿势检测模块6、用于预设运动特征变化趋势的行为规则模块5、佩戴于被监护对象患侧的穿戴式设备1、由监护人员携带的移动数字设备7以及内设有处理器和传感器的床垫8。此外，床垫8上布置有用于采集患者压力变化的压力传感器阵列以及与该压力传感器阵列相连接的处理器。在本发明中所提及的上述设备可以均为计算机处理器，图1示出脑卒中偏瘫患者用离床预警系统的简化逻辑流程图，所述逻辑流程图的操作可以表示硬件、计算机指令或其组合实现的一系列操作。在计算机指令的背景下，所述操作表示被存储在一个或多个计算机可读存储介质上的计算机可执行指令，所述计算机可执行指令在被一个或多个计算机处理器执行时执行所述的操作。The system includes anacquisition module 2 for collecting the behavior data of the monitored object, a risk controllevel division module 3 for determining the risk control level, an earlywarning information processor 4 for judging triggering early warning, and a set Theposture detection module 6, thebehavior rule module 5 used to preset the change trend of motion characteristics, the wearable device 1 worn on the affected side of the monitored object, the mobiledigital device 7 carried by the guardian, and the built-in processor and sensors for mattresses8. In addition, a pressure sensor array for collecting patient pressure changes and a processor connected to the pressure sensor array are arranged on themattress 8 . The above-mentioned devices mentioned in the present invention can all be computer processors, and Fig. 1 shows a simplified logic flow chart of a stroke hemiplegic patient's early warning system for getting out of bed, and the operation of the logic flow chart can represent hardware, computer instructions or A series of operations realized by its combination. In the context of computer instructions, the operations represent computer-executable instructions stored on one or more computer-readable storage media that, when executed by one or more computer processors, perform the described operation.

在监护人员将被监护对象调整至某一摆放姿势的情况下由监护人员通过其操作的移动数字设备7录入或由摆放姿势检测模块6确定调整后的摆放姿势，当被监护对象在床垫8上活动肢体或是自行调节摆放姿势时由设于床垫8上的处理器来获取由多个传感器所采集到的压力变化数据并基于其生成关于被监护对象的压力分布数据以及压力变化数据，该处理器将床垫8上用于分析被监护对象行为趋势、摆放姿势或摆放姿势变化趋势的压力变化相关信息(包括压力分布数据以及压力变化数据)传递至采集模块2。When the guardian adjusts the monitored object to a certain posture, the guardian is entered by the mobiledigital device 7 operated by it or theposture detection module 6 determines the adjusted posture. When the limbs are moved on themattress 8 or the posture is adjusted by itself, the processor on themattress 8 acquires the pressure change data collected by multiple sensors and generates pressure distribution data about the monitored object based on it. Pressure change data, the processor transmits the pressure change-related information (including pressure distribution data and pressure change data) on themattress 8 for analyzing the behavior trend, posture or posture change trend of the monitored object to theacquisition module 2 .

穿戴式设备1在被监护对象在床垫8上活动肢体或是自行调节摆放姿势时获取被监护对象的尤其是指患侧上肢与下肢分别对应的且用于提取第一运动特征变化趋势以及第二运动特征变化趋势的行为数据，穿戴式设备1在预设的用于实时地监测患者行为情况的预定时间间隔(可以是指1min或30min)下将其采集到的行为数据传输至采集模块2。When the wearable device 1 moves the limbs on themattress 8 or adjusts the posture by itself, the wearable device 1 obtains the data of the monitored object, especially the corresponding upper limb and lower limb of the affected side, and is used to extract the first movement characteristic change trend and Behavior data of the second motion characteristic change trend, the wearable device 1 transmits the behavior data collected by it to the acquisition module at a preset time interval (which may refer to 1min or 30min) for real-time monitoring of the patient'sbehavior 2.

采集模块2将其获取到的床垫8压力相关信息以及行为数据一并传输至摆放姿势检测模块6，并且采集模块2在获取到由该穿戴式设备1所确定的被监护对象的行为数据时基于该行为数据来生成与各行为数据对应的至少包括上肢预设运动幅度、上肢预设挪动幅度、下肢预设运动幅度以及下肢预设挪动幅度的运动特征值并将其生成的该运动特征值传输至行为规则模块5。Theacquisition module 2 transmits the acquiredmattress 8 pressure-related information and behavior data to theposture detection module 6, and theacquisition module 2 acquires the behavior data of the monitored object determined by the wearable device 1 At the same time, based on the behavior data, the motion characteristic values corresponding to each behavior data at least including the preset range of movement of the upper limbs, the preset range of movement of the upper limbs, the preset range of motion of the lower limbs, and the preset range of movement of the lower limbs are generated and the generated motion characteristics are The value is transferred to the Behavioral Rules module5.

摆放姿势检测模块6对其接收到数据(床垫8压力相关信息和/或行为数据)进行处理并对处理得到的床垫8上的压力分布情况中是否出现上下明显断层和/或一侧的压力分布相对另一侧是否呈弥散状进行判断进而判断得到被监护对象当前的摆放姿势信息，摆放姿势检测模块6将该摆放姿势信息传输至行为规则模块5与风控等级划分模块3。作为优选的实施方式，此处摆放姿势信息的确定主要是基于设于床垫8上的压力相关信息所确定的或是由护理人员在调整好摆放姿势后手动录入来确定的。Theposture detection module 6 processes the data it receives (the pressure-related information and/or behavior data of the mattress 8) and checks whether there are obvious faults up and down and/or one side in the pressure distribution on themattress 8 obtained from the processing. Judging whether the pressure distribution of the pressure distribution on the other side is in a diffuse state and then judging to obtain the current posture information of the monitored object, theposture detection module 6 transmits the posture information to thebehavior rule module 5 and the risk controllevel classification module 3. As a preferred embodiment, the determination of the posture information here is mainly determined based on the pressure-related information provided on themattress 8 or manually entered by the nursing staff after adjusting the posture.

针对摆放姿势检测模块6进一步举例说明：由于床垫8上设置有压力传感器，通过对压力传感器所采集到的数据进行处理，即可获得当前床垫8上的压力分布情况。如图2所示，当获得的压力分布情况中未出现上下明显断层、并且一侧的压力分布相对另一侧呈弥散状时，基于已知的患者患侧与床垫8之间的相对位置关系(即患者仰躺时患侧更靠近床垫8左侧或右侧的位置关系)，摆放姿势检测模块6生成当前患者处于仰卧位的体位摆放姿势的摆放姿势信息。又例如，如图2所示，当获得的压力分布情况中出现上下明显断层、并且一侧的压力分布相对另一侧呈弥散状时，基于已知的患者患侧与床垫8之间的相对位置关系，摆放姿势检测模块6生成当前患者处于健侧卧位或是患侧卧位的体位摆放姿势的摆放姿势信息。其中，“压力分布情况中出现上下明显断层”指的是：由于患者侧卧时需要将一侧上肢与一侧下肢分别搁置在枕头上，尤其是患者的患侧上肢必须完全展开地搭放在枕头上，而不同于正常人群可任意地将两侧上肢放置在距离自己头部/身体较近的位置上，以此，分别搁置在床垫8上下侧的一侧上肢与一侧下肢之间的床垫8未受到压力作用，而出现从压力分布图中观察到的上下之间存在未监测到压力作用的明显断层。并且该明显断层只存在于健侧卧位或是患侧卧位。“一侧的压力分布相对另一侧呈弥散状”指的是从压力分布图中观察可得到相对弥散程度更高的一侧，根据图2所示，相对弥散程度更高是由于伸展开的一侧上肢及下肢搭放在枕头上所引起的，因此可以确定该相对弥散程度更高的一侧为患者伸展开的一侧上肢及下肢所在的床垫8上的一侧。例如，当确定床垫8的左侧上相对弥散程度更高，并且已知患者为右侧上下肢瘫痪时，摆放姿势检测模块6生成当前患者处于患侧卧位的体位摆放姿势的摆放姿势信息。例如，当确定床垫8的右侧上相对弥散程度更高，并且已知患者为右侧上下肢瘫痪时，摆放姿势检测模块6生成当前患者处于健侧卧位的体位摆放姿势的摆放姿势信息。For further illustration of the posture detection module 6 : since themattress 8 is provided with a pressure sensor, the current pressure distribution on themattress 8 can be obtained by processing the data collected by the pressure sensor. As shown in Figure 2, when there is no obvious upper and lower fault in the obtained pressure distribution, and the pressure distribution on one side is diffuse compared to the other side, based on the known relative position between the affected side of the patient and themattress 8 relationship (that is, when the patient is lying on his back, the affected side is closer to the left side or the right side of the mattress 8), theposture detection module 6 generates the posture information of the posture that the current patient is in the supine position. For another example, as shown in FIG. 2 , when there are obvious upper and lower faults in the obtained pressure distribution, and the pressure distribution on one side is diffuse relative to the other side, based on the known distance between the affected side of the patient and themattress 8 Relative to the positional relationship, theposture detection module 6 generates posture information that the current patient is in the lying position on the healthy side or the lying position on the affected side. Among them, "obvious upper and lower faults appear in the pressure distribution" refers to: since the patient needs to rest one upper limb and one lower limb on the pillow when lying on the side, especially the affected upper limb of the patient must be fully unfolded on the pillow. On the pillow, unlike normal people, you can arbitrarily place the upper limbs on both sides at a position closer to your head/body, so that they are respectively placed between one upper limb and one lower limb on the upper and lower sides of themattress 8 Themattress 8 is not subjected to pressure, but there is an obvious fault between the upper and lower sides observed in the pressure distribution diagram that no pressure is detected. And the obvious fault exists only in the decubitus position on the healthy side or the decubitus position on the affected side. "The pressure distribution on one side is diffuse compared to the other side" refers to the side with a higher degree of relative dispersion observed from the pressure distribution diagram. According to Figure 2, the higher degree of relative dispersion is due to the stretched Therefore, it can be determined that the side with a higher degree of diffusion is the side on themattress 8 where the patient's extended upper limb and lower limb are located. For example, when it is determined that the relative diffusion degree is higher on the left side of themattress 8, and it is known that the patient is paralyzed in the upper and lower limbs of the right side, theposture detection module 6 generates a body posture posture display in which the current patient is in the lying position on the affected side. Post posture information. For example, when it is determined that the relative diffusion degree is higher on the right side of themattress 8, and it is known that the patient is paralyzed in the upper and lower limbs of the right side, theposture detection module 6 generates a posture posture that the current patient is in a lying position on the healthy side. Post posture information.

行为规则模块5基于其预设的用于预测保持在某一摆放姿势下的被监护对象在无监护的情况下可能出现的行为的运动特征变化趋势，对其接收到的由所述摆放姿势检测模块6所确定的摆放姿势信息与由所述采集模块2所确定的至少包括第一运动特征值和第二运动特征值的多个运动特征值进行处理并生成至少包括该运动特征值的且用于指示患侧上肢或患侧下肢行为情况的患肢动作数据，并将其传输至预警信息处理器4。Behavior rule module 5 is based on its preset motion feature change trend for predicting the behavior of the monitored object under a certain posture that may occur without supervision. The pose information determined by theposture detection module 6 is processed with a plurality of motion feature values determined by theacquisition module 2 and includes at least the first motion feature value and the second motion feature value, and generates a motion feature value including at least the motion feature value The action data of the affected limb used to indicate the behavior of the affected upper limb or the affected lower limb, and transmit it to the earlywarning information processor 4.

风控等级划分模块3被配置为在基于监护人员对被监护对象的摆放姿势进行调整后而由监护人员通过其操作的移动数字设备7录入或由摆放姿势检测模块6确定调整后的摆放姿势信息时和/或在基于处于无监护状态下的被监护对象在床垫8上活动肢体或是自行调节摆放姿势后而由摆放姿势检测模块6确定其自行调整后的摆放姿势信息时基于该摆放姿势信息来输出预设的与该摆放姿势相对应的且用于指示患侧肢体运动限制程度的风控等级数据，并将该数据传输至预警信息处理器4。单个风控等级包括某一摆放姿势下单侧肢体运动限制程度。风控等级包括I级(基本独立但过高估计自己活动能力)、II级(有条件独立或极轻度依赖)、III级(中度或重度依赖)和IV级(极重度或完全依赖)。进一步地，至少两个风控等级被划分为对被监护对象的独立性的评价。I级(基本独立但过高估计自己活动能力)和II级(有条件独立或极轻度依赖)被划分至被监护对象的独立性较好的评价，III级(中度或重度依赖)、IV级(极重度或完全依赖)被划分至被监护对象的独立性较差的评价。The risk controllevel classification module 3 is configured to be entered by the guardian through the mobiledigital device 7 operated by the guardian or determined by theposture detection module 6 after the guardian adjusts the posture of the monitored object. When posting the posture information and/or after the monitored object in the unsupervised state moves limbs on themattress 8 or adjusts the posture by itself, theposture detection module 6 determines its self-adjusted posture When information is based on the posture information, the preset risk control level data corresponding to the posture and used to indicate the degree of movement restriction of the affected limb is output, and the data is transmitted to the earlywarning information processor 4 . A single risk control level includes the degree of restriction of unilateral limb movement in a certain posture. Risk control levels include level I (basically independent but overestimated own mobility), level II (conditionally independent or very lightly dependent), level III (moderately or heavily dependent) and level IV (extremely heavy or completely dependent) . Further, at least two risk control levels are divided into the evaluation of the independence of the monitored object. Level I (basically independent but overestimating one's own activity ability) and level II (conditional independence or very light dependence) are divided into the independent evaluation of the warded object, level III (moderate or severe dependence), Level IV (Extremely or Totally Dependent) is assigned to the assessment of the ward's poor independence.
