Design And Realization Of Training System Of High Intelligent Maternity First-aid Simulator

With the continuous developing of material technology, computer technology and embedded system, medical simulator training system is introduced into medical colleges, all kinds of hospitals and medical institutions. However, at present, most training systems of medical patient simulators are specially designed and developed for comprehensive first-aid training, which isn't perfectly suitable for the obstetrical first-aid training. Therefore, there is a demand for a new medical simulator training system which is developed according to requirements of obstetrics first-aid.Based on demands of clinical maternal first-aid training, training system of high intelligent maternal first-aid patient simulator adopts the most popular design method of physical driven medical model in the world to develop the Manikin. This system can not only be used to the technological training of medical normal operation such as oropharyngeal and nasal intubation techniques, artificial respiration and external chest compression, pace-making and external defibrillation, blood pressure and oxyhemoglobin saturation, and electrocardiogram monitoring, but also be use to operating skill training such as demonstration on the delivery process of puerperae, auscultation of fetal heartbeats, auscultation of puerperae's chest and doctors' medications.This paper mainly includes the following aspects. First, by studying the vital signs which are necessary to be simulated in puerpera medical teaching, this paper analyses the functional requirements, integral structure, and constitutions of each functional unit in the high intelligent maternal first-aid simulator training system. Second, by splitting functions of the hardware system, the integral structure of hardware system is designed so as to complete its structure diagram. Third, by determining the concrete implementation procedures of each training item in the system, this paper has conceptually designed each parts of the hardware. Fourth, by using the module of Wifi and utilizing the Wifi ad-hoc networking technology, the information exchange between the upper computer and the lower computer can be realized, which can send instructions to demand simulators to simulate physiology characteristics and collect the operating personnel' series of operating information to simulators. Fifth, by minutely designing the main control modules which are the core of the whole hardware system, the main components and technical schemes are selected out and the control circuit of the main control modules has been designed which based on the TI MSP430F5438 A micro-controller. Sixth, in the Embedded Workbench for MSP430 version,EW430, provided by IAR Systems, the drive program and the software program of the main control module are wrote by using standard C language and the dedicated instruction set.This system has been successfully developed and put on the market. At the development stage, this system has been certified its validity and effectiveness through a series of tests like unit test, functional test, system test, and user validation test. Meanwhile, ten model machines are tentatively tested on the same standard in order to verify the reliability of the system and make sure its large-scale production.
