Development of portable field pressurized cryotherapy system
Objective To design a portable field pressurized cryotherapy system for patients in field medical treatment or mobile cryotherapy.Methods AT89C52 was used as the main control chip,semiconductor refrigeration chip was used for cooling water,pressurized air pump was used to pressurize internal part of cryotherapy system.On the one hand,the cooling water was pumped to cryotherapy sleeve,and on the other hand,the cooling sleeve was inflated and pressurized to achieve pressure cryotherapy of patient.The system used DS18B20 temperature sensor to collect temperature and BMP280 pressure sensor to collect pressure,which was convenient for accurate monitoring and control of pressurized cryotherapy.Results The whole structure of pressurized cryotherapy system was integrated and lightweight designed.Each circuit module was designed with low power consumption and intelligent wake-up design,which with complete functional selection of cryotherapy temperature,cryotherapy pressure,cryotherapy time and so on.After clinical testing,the field portable pressurized cryotherapy system met outdoor cryotherapy requirements,which were small volume,light weight,easy to carry,and showed low power consumption,long battery life,strong field capability,with simple operation and well-designed features.Conclusion It is demonstrated that the system is suitable for patients with field medical and outdoor pressurized cryotherapy,which of great significance for improving cryotherapy of patient.
