无线输液报警器的设计与研制

Design and Manufacture of Electronic Wireless Infusion Alarm

根据实际生活中输液的环境研究,设计了一种新型的无线输液报警器。采用压力传感器与相关电路模块实现自动报警功能;采用PT2262、PT2272实现无线传输和编码功能;用不同电阻来实现量程选择功能。与现有的输液报警器相比有大幅度的创新与改进,功能更多、体积更小、成本更低、使用方便、灵敏度高,更适合实际中的各种医疗环境下的应用。

In this paper, according to the nor^nal 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 re-alize 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.
