一种家用式缺血预适应训练仪的设计与实现

Design and Implementation of Household Ischemic Preconditioning Training Instrument

目的设计一款用于脑卒中康复治疗及卒中预防的家用式上肢缺血预适应训练设备,并分析本装置压力控制的稳定性及测量的准确性。方法基于单片机、气泵、电磁阀、袖带等组件,搭建电控的袖带式肢体加压阻断装置作为臂带机;编写在安卓平台下运行的缺血预适应训练管理软件,可以通过蓝牙控制臂带机进行缺血训练和血压、心率的测量,并对训练数据进行显示和存储。结果家用式缺血预适应训练仪原理样机经压力控制稳定度测试,对于压力控制的稳定度良好;经血压、心率测量准确度测试,与测量血压、心率较为准确的欧姆龙电子血压计所测结果比较,差异无统计学意义(P>0.05),对于血压、心率的测量较为准确。结论本设备适用于脑卒中患者和脑卒中高发病风险者进行康复治疗和卒中预防训练,同时为家用式缺血预适应训练仪的开发与设计提供了一种新的思路。

Objective To design a home-style upper limb ischemia preconditioning training device for cerebral stroke rehabilitation and stroke prevention,and analyze the stability of pressure control and measurement accuracy of the device.Methods Based on the single-chip microcomputer,air pump,solenoid valve,cuff and other components,an electronically controlled cuff-type limb pressurization blocking device was built as the armband machine.The ischemic preconditioning training management software running on the Android platform was compiled,which could control the armband machine through Bluetooth to perform ischemic training,measure blood pressure and heart rate,display and store the training data.Results The prototype of the principle of household ischemic preconditioning training device was tested by pressure control stability,and the stability of pressure control was good.Through the accuracy test of blood pressure and heart rate measurement,there was no significant statistical difference between the device and Omron electronic sphygmomanometer(P>0.05),which was more accurate in measuring blood pressure and heart rate.Conclusion This device can be used for rehabilitation treatment and stroke prevention training for cerebral stroke patients and those at high risk of stroke,and it also provides a new idea for the development and design of household ischemic preconditioning training instrument.
