背景技术Background technique
疾病往往带有危急和复杂的特点，特别是急诊在进行抢救和应对一些突发事件时，考虑到学生能力和经验的缺乏以及病人的安全需要，不能让他们承担第一处理者，这样就造成了学生理论和实践难以结合。学生的临床技能所面临的问题日益凸现。Diseases are often critical and complicated. Especially when emergency rescue and emergency response, students' lack of ability and experience and the safety needs of patients cannot be allowed to be the first handlers, which results in It is difficult for students to combine theory and practice. Problems facing students' clinical skills are becoming increasingly prominent.
随着近年来诊疗安全意识的空前强调和医学伦理学的发展以及现代仿生学和电脑软件技术的飞跃发展，具有“生理驱动功能”的真正意义上的高端智能模拟人呼之欲出，高度仿真的临床情境将开启医学教育的新篇章。基于智能模拟技术的仿真人能够模拟疾病的异常体征和各种病理生理指标的变化，甚至能实现“医患”的互动交流，创设了更贴近临床实际工作的场景，在医学教育中不仅为学习者提供一个无风险的学习临床知识和技能的条件与环境，而且对于培养医学生的临床思维能力、实践技能、团队协作精神提供了新的教学模式。With the unprecedented emphasis on medical safety awareness and the development of medical ethics in recent years, as well as the rapid development of modern bionics and computer software technology, a truly high-end intelligent simulator with "physiologically driven functions" is coming soon, and highly simulated clinical situations It will open a new chapter in medical education. The artificial human based on intelligent simulation technology can simulate the abnormal signs of the disease and the changes of various pathophysiological indicators, and even realize the interactive communication between "doctors and patients", creating a scene closer to the actual clinical work, which is not only for learning in medical education It provides a risk-free condition and environment for learning clinical knowledge and skills, and provides a new teaching mode for cultivating medical students' clinical thinking ability, practical skills and teamwork spirit.
呼吸频率，是急性呼吸功能障碍的敏感指标。不论是医生还是护理人员都把它作为生命指征之一，另外，情绪变化可影响呼吸频率。肺活量是一次呼吸的最大通气量，在一定意义上反映了呼吸机能的潜在能力。一般地说，健康状况愈好的人肺活量愈大。肺活量具体在人体外在的表现男性为肚子的起伏，女性则为胸部的起伏。因此，测定呼吸频率和强度在临床上有很重要的意义。Respiratory rate is a sensitive indicator of acute respiratory dysfunction. Both doctors and nurses regard it as one of the vital signs. In addition, emotional changes can affect the respiratory rate. Vital capacity is the maximum ventilation volume of one breath, which reflects the potential capacity of respiratory function in a certain sense. Generally speaking, the better the health status, the greater the lung capacity of a person. The specific external manifestation of lung capacity in the human body is the rise and fall of the stomach for men, and the rise and fall of the chest for women. Therefore, the determination of respiratory frequency and intensity is of great clinical significance.
为了避免不必要的医疗纠纷，同时模拟的临床工作场景可反复再现，最大程度地解决临床教学资源的匮乏，具有人体在不同生理状况下呼吸变化，并且可根据实际需要自行编制多种模拟病例的智能化呼吸模拟装置的研发势在必行。In order to avoid unnecessary medical disputes, the simulated clinical work scene can be reproduced repeatedly, and the lack of clinical teaching resources can be solved to the greatest extent. It has the ability to change the breathing of the human body under different physiological conditions, and can compile a variety of simulated cases according to actual needs. The research and development of intelligent breathing simulation device is imperative.

具体实施方式detailed description
本发明的优选实施例详述如下：Preferred embodiments of the present invention are described in detail as follows:
实施例一：Embodiment one:
在本实施例中，参见图1和图2，一种人体呼吸模拟装置，包括电源装置，以气泵5作为输气动力源，气泵5与储气包9连通，储气包9采用软且有弹性的材料制成，由气泵5向储气包9中输气，储气包9的气体再输出给两组电磁阀2，其中第一组的电磁阀2控制储气包9向两个气囊4充气，还控制两个气囊4放气，来模拟女性的胸部的吸气和排气，从而模拟出人体在呼吸状态下胸部的跳动，其中第二组的电磁阀2控制由储气包9向另外一个气囊4充气，还控制气囊4放气，来模拟男性吸气和排气的肚子起伏，从而模拟出人体在呼吸状态下肚子的跳动，采用微处理器1通过一系列继电器3来对应控制各电磁阀2，从而使对应的电磁阀2处于通或断的状态，进而控制各气囊4充气和放气，微处理器1采用单片机，气囊4采用软且有弹性的材料制成，至少在各气囊4上对应安装气压表8，气压表8将实时检测对应气囊4的压力信号向微处理器1反馈，当气压表8检测到的气囊4的压力高于设定的阈值时，通过信息反馈，控制对应气囊4的电磁阀2的继电器3断开，从而使气泵5停止工作，当气压表8检测到的气囊4的压力低于设定的阈值时，通过信息反馈，控制对应气囊4的电磁阀2的继电器3吸合，从而使气泵5开始输气工作。本实施例人体呼吸模拟装置参考肺部结构进行设计，根据各种病理生理指标的变化，人类呼吸的频率和强度也会随之波动。为了模拟出肺部呼吸的效果，在气路的塑料硬管末端套上各气囊4，这样在气体压力变化的时候就能感受到肺部呼吸。本实施例人体呼吸模拟装置采用自适应动力方案，本系统的动力驱动为气压，为了给系统供给合适的气压，采用在气泵5的输出端口安装一个储气包9作为储气设备从而给本系统提供稳定动力。因为气泵5一直工作情况下储气包9气压就会过大，为了保护气囊4不使其气压过大，本系统中增加了气压表8，在高于设定的阈值时下发低电平使继电器3断开，从而气泵5停止工作。当低于设定的阈值时下发高电平使继电器3吸合，气泵5开始工作。根据人体胸部和肚子呼吸强度变化，本实施例的气源气泵5的输出端分别接上电磁阀2和气囊4，控制这两种模块的工作，从而形成胸部和肚子的跳动和强弱变化。单片机控制继电器3从而控制电磁阀的工作，电磁阀2的开合使气囊4充放气形成胸部和肚子跳动。In this embodiment, referring to Fig. 1 and Fig. 2, a human breathing simulation device includes a power supply device, and an air pump 5 is used as a power source for conveying air. The air pump 5 communicates with an air storage bag 9. Made of elastic material, the air pump 5 sends air to the air storage bag 9, and the gas in the air storage bag 9 is then output to two sets of solenoid valves 2, wherein the first group of solenoid valves 2 controls the flow of the air storage bag 9 to the two air bags. 4 is inflated, and two airbags 4 are also controlled to deflate to simulate the inhalation and exhaust of the female chest, thereby simulating the beating of the chest of the human body in the breathing state, wherein the solenoid valve 2 of the second group is controlled by the air storage bag 9 Inflate another airbag 4, and control the deflation of the airbag 4 to simulate the ups and downs of the belly of a man inhaling and exhaling, thereby simulating the beating of the belly of the human body in the breathing state, using a microprocessor 1 through a series of relays 3 to correspond Control each solenoid valve 2, so that the corresponding solenoid valve 2 is in the on or off state, and then control the inflation and deflation of each airbag 4, the microprocessor 1 adopts a single-chip microcomputer, and the airbag 4 is made of soft and elastic material, at least Correspondingly install air gauge 8 on each air bag 4, air gauge 8 will detect the pressure signal of corresponding air bag 4 in real time and feed back to microprocessor 1, when the pressure of air bag 4 that air gauge 8 detects is higher than the threshold value of setting, by Information feedback, control the relay 3 of the solenoid valve 2 corresponding to the airbag 4 to be disconnected, so that the air pump 5 stops working, and when the pressure of the airbag 4 detected by the air gauge 8 is lower than the set threshold, the corresponding airbag is controlled through information feedback The relay 3 of the solenoid valve 2 of 4 pulls in, so that the air pump 5 starts to deliver gas. The human breathing simulation device in this embodiment is designed with reference to the structure of the lungs. According to the changes of various pathophysiological indicators, the frequency and intensity of human breathing will also fluctuate accordingly. In order to simulate the effect of lung breathing, each airbag 4 is put on the end of the plastic hard tube of the air path, so that the lung breathing can be felt when the gas pressure changes. The human breathing simulation device of this embodiment adopts an adaptive power scheme, and the power drive of the system is air pressure. In order to supply suitable air pressure to the system, an air storage bag 9 is installed at the output port of the air pump 5 as an air storage device to provide the system Provide stable power. Because the air pressure of the air storage bag 9 will be too large when the air pump 5 is working all the time, in order to protect the air bag 4 from excessive pressure, a barometer 8 is added to the system, and a low level is sent when the air pump 5 is higher than the set threshold. Relay 3 is disconnected, thereby air pump 5 stops working. When it is lower than the set threshold, a high level is sent to make the relay 3 pull in, and the air pump 5 starts to work. According to the variation of breathing intensity of human chest and belly, the output ends of the air source air pump 5 of this embodiment are respectively connected with electromagnetic valve 2 and air bag 4 to control the work of these two modules, thereby forming the beating and strength changes of chest and belly. The single-chip microcomputer controls the relay 3 so as to control the work of the solenoid valve, and the opening and closing of the solenoid valve 2 makes the air bag 4 inflated and deflated to form the chest and stomach to beat.

The control command of the upper computer is sent to the WIFI module, and then transmitted to the microprocessor 1 through the serial port. Microprocessor 1 receives control instructions sent by the PC control terminal, and microprocessor 1 controls each module, and then controls the switch of solenoid valve 2, so that there will be different beating frequencies and intensities of the stomach and chest, resulting in different human bodies. The beating of the chest and stomach in a healthy physiological state forms a different physiological state.
