目前很多医院病人输液呼叫依赖于病人或者病人家属以及医护人员，这很大程度依赖于病人及家属的主观注意力以及医护人员的输液管理，会经常出现点滴打完没有及时呼叫和处理的情况，这具有一定风险，会给病人及家属增加负担和压力，同时也给医生和护士带来麻烦。本文对医生、病人及家属的需求进行分析，研究设计一款计算机控制的医疗输液呼叫设备，进而很好地解决这一问题。

At present, patient infusion calls in many hospitals depend on patients, their families and medical staff, which largely depend on the subjective attention of patients and their families and the management of transfusion by medical and nursing personnel. It often occurs when the drip is finished without timely calling and handling, which carries certain risks, increases the burden and pressure on patients and their families, and also brings problems to doctors and nurses. In this paper, the needs of doctors, patients and family members are analyzed, and a computer-controlled medical infusion calling equipment is designed to solve this problem well.
