伴随着医疗技术的发展，人们对医疗服务质量的要求越来越高。目前市面上的医院病人呼叫系统，无法满足当下医院高效率的工作需求。急需设计一款使用方便、功能齐全的医院病人呼叫系统显得尤为重要。本设计以STM32单片机为核心设计的一款医院智能呼叫系统。该系统包括主机和从机两部分。主机包含STM32单片机组成的最小系统、按键电路、OLED显示电路、声光报警电路、蓝牙传输电路。从机包括按键电路、LED指示灯电路、蓝牙传输电路、温湿度检测电路、脉搏检测电路、血压检测电路以及STM32单片机组成的最小系统。本设计的从机通过4个按键模拟4个病人呼叫按键，当病人按下呼叫按键时，对应指示灯点亮，当医护人员过来时，再次按下按键，对应的指示灯熄灭。主机用于医护人员观察按键，通过4个按键作为回应键，当有病人呼叫时，进行声光报警，医护人员按下相对应的按键作为回应，回应后，声光报警取消，从机常亮灯闪烁，若同时有两个病人呼叫，按照先后顺序进行显示。当没有人呼叫时，显示温湿度、心率、血压等值。通过实践表明，该医院智能呼叫系统能够有效提高医院工作效率，为促进智能医院贡献一份绵薄之力。

With the development of medical technology, people have higher and higher requirements for the quality of medical service. At present, the hospital patient call system on the market can not meet the high efficiency of the current hospital work needs. The urgent need to design a convenient, functional hospital patient call system is particularly important.This design takes STM32 single chip microcomputer as the core design of a hospital intelligent call system. The system consists of two parts: host and slave. The host includes the minimum system composed of STM32 single chip microcomputer, key circuit, OLED display circuit, acousto-optic alarm circuit and Bluetooth transmission circuit. The slave includes key circuit, LED indicator circuit, Bluetooth transmission circuit, temperature and humidity detection circuit, pulse detection circuit, blood pressure detection circuit and STM32 microcontroller composed of the minimum system. The slave machine of this design simulates 4 patient call buttons through 4 buttons. When the patient presses the call button, the corresponding indicator light will be lit. When the medical staff comes, the corresponding indicator light will be extinguished by pressing the button again. The host is used for medical staff to observe the buttons, using four buttons as the response key, when a patient calls, sound and light alarm, medical staff press the corresponding button as a response, after the response, the sound and light alarm is cancelled, and the slave is steady on and blinking. If two patients call at the same time, it will be displayed in sequence. When no one calls, the temperature and humidity, heart rate, and blood pressure are displayed. The practice shows that the hospital intelligent call system can effectively improve the working efficiency of the hospital and contribute to the promotion of intelligent hospitals..
