病区护理站无线呼叫系统的设计

Design of Wireless Sickroom Calling System

目的:解决护理站护士到病室内进行治疗护理时,听不到其他病室患者呼叫的蜂鸣声,造成危急患者得不到及时抢救的问题。方法:利用单片机及无线数传模块,对原病区护理站传呼系统进行了改进,通过单片机进行特定的信息编码处理,再用无线数传模块进行数据的发送与接收,设计出了小巧的便携式呼叫信息接收机。结果:接收机的可靠接收距离在800m以内,具有16个信道可供不同楼层选用,具有数据传送校验功能,功耗小,性能稳定可靠。结论:值班护理人员能随身携带病室呼叫信息接收机,在护理站内不管在那个病室都能随时接收到患者的呼叫信息,提供迅速及时的治疗和护理,提高患者对护理工作满意度;中午和夜间还可将病区护理站传呼系统的声音关闭,有利于患者休息。设计改进方法可用于任何型号的呼叫系统,弥补当前医用传呼系统的不足。

Objective To solve the problem that the timely salvation can not be provided to the critical sick when nurses are not in nurse station and can not hear the sound of buzzer, Methods By utilizing SCM and wireless numerical transmission module, the former sick area treatment station calling system was developed. The special information was coded through SCM. The dada were sent and received with wireless numerical transmission module. In this way, a portable calling information receiving machine was designed, Results The reliable receiving distance of receiving machine is in the bound of 800 meters, and it provides 16 channels to use for different floors, having data transmission check function, little power loss, performance steady and credibility.Conclusion With sickroom calling message receiving machine, the nurse on duty can receive the calling message of the sick at any time and in any room, so rapid treatment can be provided on time, improving the satisfaction degree of sick. Besides, the sound of the calling system in the sick area treatment station can be shut down at noon and night, thus providing better circumstance for the sick to rest. The design is suitable for the calling system in any type and makes up the original shortages of the calling system in hospital. [Chinese Medical Equipment Journal ,2008,29（ 11 ） ：17-19]
