本发明属于医疗器械领域。特别涉及一种利用传感器监测多种信息的智能引流管及监测系统。The invention belongs to the field of medical equipment. In particular, it relates to an intelligent drainage tube and a monitoring system which utilize sensors to monitor various information.
背景技术Background technique
引流管是目前外科引流的主要工具，其主要的功能是将人体组织间或体腔中积聚的脓、血、液体导引至体外，防止术后感染与影响伤口愈合。引流管的应用范围很广，可用于伤口、尿液的引流，也可用于胸腔、脑腔、腹腔等部位的引流。Drainage tube is currently the main tool for surgical drainage. Its main function is to guide pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing. Drainage tubes have a wide range of applications, and can be used for drainage of wounds and urine, and can also be used for drainage of chest cavity, brain cavity, abdominal cavity and other parts.
引流是引流管最重要的功能，但目前引流管在使用过程中存在两个主要问题，第一是无法实时监测引流管的引流状态，而实时监测各时期引流管的各种引流状态，对于实时了解患者的恢复情况有着重要意义，尤其是在引流过程中，引流管容易被消化液、腹腔液、脓液、切口渗出液等中的组织碎片或凝血堵塞，导致引流不畅，如果处理不及时将会造成被引流部位出现积水、感染等症状，严重时危及患者生命，而护士和家属不可能实时全面的监测引流管的状态，因此实现实时监测引流管的引流状态对医生和患者都有重大意义。第二是目前的引流管获得的信息有限，而用陀螺仪和加速度计获取患者体位、运动状态等信息可以用于辅助判断引流管的引流状态，另外，临床医生在引流时往往需要测量组织间、体腔或血液的压力、温度等多种参数，根据患者的实际病情采取更精准、更有效的治疗方案。Drainage is the most important function of the drainage tube, but there are two main problems in the use of the drainage tube at present. The first is that it is impossible to monitor the drainage status of the drainage tube in real time. It is of great significance to understand the patient’s recovery, especially during the drainage process, the drainage tube is easily blocked by tissue fragments or coagulation in digestive juice, peritoneal fluid, pus, incision exudate, etc., resulting in poor drainage. In time, it will cause symptoms such as water accumulation and infection at the drainage site, which will endanger the life of the patient in severe cases. However, it is impossible for nurses and family members to monitor the status of the drainage tube in real time and comprehensively. Therefore, real-time monitoring of the drainage status of the drainage tube is beneficial to both doctors and patients. has great significance. The second is that the information obtained by the current drainage tube is limited, and the information such as the patient's body position and motion status obtained by the gyroscope and accelerometer can be used to assist in judging the drainage status of the drainage tube. In addition, clinicians often need to measure interstitial space during drainage , body cavity or blood pressure, temperature and other parameters, according to the actual condition of the patient to adopt a more accurate and effective treatment plan.
目前一些专利提出了一些相关监测方法，比如中国专利：CN201110162589.1 一种颅内压监测引流管、CN201610451591.3一种膀胱压力信息的监测设备、系统以及方法，但是解决的问题有限。例如，南京航空航天大学提出的“颅内压监测引流管”具有实时监测颅内压力的同时可以进行引流的功能，但是，其存在两个问题，第一，不具有监测引流管引流状态的功能，因此，一旦出现引流管堵塞未及时发现，导致颅内压升高的情况将对患者造成不可挽回的二次伤害；第二，只能获得压力信息，无法获取患者的温度以及与患者的体位、运动等状态相关的角速度、加速度等信息；其次是中国科学院苏州生物医学工程技术研究所提出的监测方法，其引流管功能是将人体膀胱尿液导引至体外，其中引流管中带有压力传感器可以采集膀胱内压力信息，具有一定的判断引流管引流状态的功能，但是，其使用的传感器单一，获得的信息有限，当引流管堵塞初期压力变化不明显时以及引流管中的引流液出现液体气体混合等复杂情况时，仅仅靠压力信息其并不一定能准确的判断引流管真实的引流状态；另外，其仅仅适用于膀胱引流方面，不具有普遍适用性。由此可知，原有的技术存在智能化程度低，不能全面、准确的判断引流管的引流状态，获得信息有限等等的不足。所以，迫切需要采用多传感器获得多方面信息等方法解决上述问题，进一步提高引流管的智能化。At present, some patents have proposed some related monitoring methods, such as Chinese patent: CN201110162589.1 a drainage tube for intracranial pressure monitoring, CN201610451591.3 a monitoring device, system and method for bladder pressure information, but the problems solved are limited. For example, the "intracranial pressure monitoring drainage tube" proposed by Nanjing University of Aeronautics and Astronautics has the function of real-time monitoring of intracranial pressure and drainage at the same time, but it has two problems. First, it does not have the function of monitoring the drainage status of the drainage tube Therefore, once the blockage of the drainage tube is not detected in time, the increase in intracranial pressure will cause irreparable secondary damage to the patient; second, only the pressure information can be obtained, and the temperature of the patient and the position of the patient cannot be obtained , motion and other information related to angular velocity, acceleration, etc.; followed by the monitoring method proposed by the Suzhou Institute of Biomedical Engineering Technology, Chinese Academy of Sciences. The sensor can collect the pressure information in the bladder and has a certain function of judging the drainage status of the drainage tube. However, the sensor used is single and the information obtained is limited. In complex situations such as liquid gas mixing, pressure information alone may not be able to accurately judge the true drainage status of the drainage tube; in addition, it is only applicable to bladder drainage and does not have universal applicability. It can be seen that the original technology has the shortcomings of low intelligence, inability to comprehensively and accurately judge the drainage status of the drainage tube, and limited information. Therefore, there is an urgent need to use multiple sensors to obtain various information to solve the above problems and further improve the intelligence of the drainage tube.

图4所示为实时监测引流管的工作状况曲线图。利用光学传感器2.3监测引流液体在引流管管道里流动状态，当光照透过引流管壁后再反射到光学传感器 2.3时，光照有一定的衰减。由于引流管壁对光的吸收是基本不变的，而引流液里存在血液、脓液、组织残渣等，则会造成对光吸收的变化，因此可以利用这些不同来判断引流管的引流状态。引流液体在引流管管道里的流动情况复杂多变，如图4所示的情况，当光转换成电信号时，由于引流液对光的吸收有变化而引流管壁对光的吸收基本不变，所以得到的信号就可以分为直流信号和交流信号。当引流管引流通畅时，每当引流液流经光学传感器时，都会得到交流信号，如图4 中a,b所示：其(a)液体流量大,传感器接收到的信号量的状态为变化小的波动状态；(b)液体流量小,空气和流体间隔出现，传感器接收到的信号量有突变；当引流管出现堵塞时，得到的信号将会长时间是直流信号，如图4中c,d所示，其中(c)在传感器之前的引流管有堵塞，液体不流动，传感器接收到的信号量基本不变；(d)在传感器之后的引流管有堵塞，液体不流动，传感器接收到的信号量基本不变。因此，分析提取的电信号的变化情况，就能判断出引流管的引流情况；上述四种状态仅为引流管实际引流状态中的其中的四种状态，而不是全部状态，其他引流状态本发明也可监测，属于本发明保护范围。Figure 4 shows the real-time monitoring curve of the working status of the drainage tube. The optical sensor 2.3 is used to monitor the flow state of the drainage liquid in the drainage tube. When the light passes through the wall of the drainage tube and then reflects to the optical sensor 2.3, the light has a certain attenuation. Since the absorption of light by the wall of the drainage tube is basically unchanged, the presence of blood, pus, tissue residue, etc. in the drainage fluid will cause changes in the absorption of light. Therefore, these differences can be used to judge the drainage status of the drainage tube. The flow of drainage liquid in the drainage tube is complex and changeable. As shown in Figure 4, when the light is converted into an electrical signal, the absorption of light by the drainage tube wall is basically unchanged due to the change in the absorption of light by the drainage fluid. , so the obtained signal can be divided into DC signal and AC signal. When the drainage tube drains smoothly, every time the drainage fluid flows through the optical sensor, an AC signal will be obtained, as shown in a and b in Figure 4: (a) the liquid flow rate is large, and the state of the signal received by the sensor is changing Small fluctuation state; (b) The liquid flow rate is small, the gap between air and fluid appears, and the signal received by the sensor has a sudden change; when the drainage tube is blocked, the obtained signal will be a DC signal for a long time, as shown in Figure 4 c , as shown in d, where (c) the drainage tube before the sensor is blocked, the liquid does not flow, and the signal received by the sensor remains basically unchanged; (d) the drainage tube behind the sensor is blocked, the liquid does not flow, and the sensor receives The received semaphore is basically unchanged. Therefore, by analyzing the variation of the extracted electrical signal, the drainage situation of the drainage tube can be judged; the above four states are only four states in the actual drainage state of the drainage tube, not all states, and other drainage states of the present invention It can also be monitored and belongs to the protection scope of the present invention.
图5所示为监测装置的电容传感器安装示意图，其中a在引流管内壁上；b 在引流管外壁上。由于电容传感器2.1的电容极板安装在引流管1内外表面上；电容传感器2.1的电容极板间的介电常数的改变会导致极板两侧电压值的改变，当引流管内有引流液通过时，电容极板间的介电常数发生改变，从而使电压值发生改变；因此，当引流管引流通畅时，每当引流液流经电容传感器时，都会得到交流信号(如图4中a,b所示)：当引流管出现堵塞时，得到的信号将会长时间是直流信号(如图4中c，d所示)；由此，可以从分析提取的电信号的变化情况，就能判断出引流管的引流情况。Figure 5 is a schematic diagram of the installation of the capacitive sensor of the monitoring device, where a is on the inner wall of the drainage tube; b is on the outer wall of the drainage tube. Because the capacitive plates of the capacitive sensor 2.1 are installed on the inner and outer surfaces of the drainage tube 1; the change of the dielectric constant between the capacitive plates of the capacitive sensor 2.1 will cause the voltage value on both sides of the plates to change. , the dielectric constant between the capacitive plates changes, so that the voltage value changes; therefore, when the drainage tube drains smoothly, every time the drainage fluid flows through the capacitive sensor, an AC signal will be obtained (a, b in Figure 4 as shown): When the drainage tube is blocked, the obtained signal will be a DC signal for a long time (as shown in c and d in Figure 4); thus, it can be judged from the change of the electrical signal extracted from the analysis Drainage of the drainage tube.
图6为监测装置的电阻或阻抗传感器安装示意图，其中a在引流管内壁上； b在引流管外壁上。将电阻或阻抗传感器2.2粘贴在引流管1内外表面上；当引流管1内有引流液流经电阻或阻抗传感器2.2时，会导致电阻或阻抗传感器2.2 电阻的变化，电阻的变化经电路处理后，以电信号的方式输出，从而转换成电信号的改变；当引流管引流通畅时，每当引流液流经电阻或阻抗传感器时，都会得到交流信号(如图4中a,b所示)；当引流管出现堵塞时，得到的信号将会长时间是直流信号(如图4中c，d所示)；由此，可以从分析提取的电信号的变化情况，就能判断出引流管的引流情况。Fig. 6 is a schematic diagram of the installation of the resistance or impedance sensor of the monitoring device, wherein a is on the inner wall of the drainage tube; b is on the outer wall of the drainage tube. Paste the resistance or impedance sensor 2.2 on the inner and outer surfaces of the drainage tube 1; when the drainage fluid in the drainage tube 1 flows through the resistance or the impedance sensor 2.2, it will cause the resistance of the resistance or the impedance sensor 2.2 to change, and the change of the resistance is processed by the circuit , which is output in the form of an electrical signal, and thus converted into a change of the electrical signal; when the drainage tube is unobstructed, whenever the drainage fluid flows through the resistance or impedance sensor, an AC signal will be obtained (as shown in a,b in Figure 4) ; When the drainage tube is blocked, the signal obtained will be a DC signal for a long time (as shown in c and d in Figure 4); thus, it can be judged from the variation of the electrical signal extracted from the analysis that the drainage tube drainage situation.
另外，本发明的体内监测单元3的第二传感模块12具有多传感器(多种类型传感器、同种类型多个传感器)位于引流管前端，当引流管插入人体内部进行引流时，多个传感器与人体内腔直接接触，可以更准确的获得患者多种生理参数(利用压力传感器、温度传感器监测压力和温度)与活动状态(利用陀螺仪、加速度计监测角速度和加速度)，因此，方便医生实时了解患者多种信息以采取更合理的治疗方案。具体监测多种信息的方法步骤如下：In addition, the second sensing module 12 of the in-vivo monitoring unit 3 of the present invention has multiple sensors (multiple types of sensors, multiple sensors of the same type) located at the front end of the drainage tube. When the drainage tube is inserted into the human body for drainage, the multiple sensors Direct contact with the inner cavity of the human body can more accurately obtain various physiological parameters of the patient (monitoring pressure and temperature using pressure sensors and temperature sensors) and activity status (monitoring angular velocity and acceleration using gyroscopes and accelerometers), so it is convenient for doctors to real-time Understand various information of patients to adopt more reasonable treatment plan. The specific steps for monitoring various information are as follows:
1)开启上位机16，建立上位机与监测单元的连接关系；1) Turn on the upper computer 16, and establish the connection relationship between the upper computer and the monitoring unit;
2)上位机16发送控制指令，监测单元准备开始采样工作；2) The host computer 16 sends a control command, and the monitoring unit is ready to start sampling work;
