Design and Manufacture of Electronic Wireless Infusion Alarm

In this paper,according to the normal environment of transfusion,we designed a new type of wireless infusion alarm device,which uses pressure sensor and some electronic modules to realize the function of automatic warning,PT2262 and PT2272 realize the function of wireless communication,different resistances realize the function of selective range. The device compares with present infusion alarm in the market,which has significant innovation and improvement,more function,less volume,lower cost and higher sensitivity,and suit all kinds of medical environment more than others.
