摘  要
醫(yī)院已經(jīng)從人工管理模式向智能化方向發(fā)展。
“病床呼叫系統(tǒng)”可以實(shí)現(xiàn)對(duì)病房的智能化管理，可實(shí)現(xiàn)呼叫、求救警報(bào)、信息存儲(chǔ)、顯示等等功能?；颊咴谧≡浩陂g，可能會(huì)在任意時(shí)間請(qǐng)求醫(yī)生或護(hù)士進(jìn)行診斷或護(hù)理。病床求助呼叫是傳送臨床信息的重要手段，病床呼叫系統(tǒng)是患者向值班醫(yī)生或護(hù)士發(fā)出緊急呼叫的工具，要將患者的請(qǐng)求快速傳給值班醫(yī)生或護(hù)士，并在護(hù)士站的監(jiān)控中心留下準(zhǔn)確完整的記錄，是提高醫(yī)院和病室護(hù)理的重要組成部分。
本系統(tǒng)以STC89C51單片機(jī)為核心輔以4個(gè)外接鍵盤、LED點(diǎn)陣顯示電路和部分簡(jiǎn)單模擬和數(shù)字電路組成的，能夠?qū)崿F(xiàn)病人和醫(yī)護(hù)人員之間信息的傳遞。在該設(shè)計(jì)中模擬2個(gè)病房每個(gè)病房2個(gè)病床編號(hào)0101/0102和0201/0202，每個(gè)病床都有一個(gè)按鍵，當(dāng)患者有需要時(shí)，按下按鍵，此時(shí) 值班室的顯示屏可顯示此患者的病房號(hào)和床位號(hào)，醫(yī)護(hù)人員按下“響應(yīng)”鍵取消當(dāng)前呼叫。此系統(tǒng)能夠?yàn)獒t(yī)院提供一個(gè)成本低、效率高、操作方便和易于安裝維護(hù)的快捷系統(tǒng)。

Abstract
Management model of hospital from artificial intelligent direction.
Bed call system can achieve the intelligent management of the ward; can realize the call, distress alert, information storage, display and more. Patients during hospitalization may at any time request the doctor or nurse for the diagnosis or nursing. Beds help call is an important means of transmission of clinical information, bed call system is a tool for patients issued an urgent call to the on duty doctor or nurse, you want to the patient's request quickly passed to the duty doctor or nurse, and left the nurses’ station monitoring center accurately the complete record is an important part to improve the care of hospitals and sick rooms.
STC89C51 single-chip at the core of the system combined with 4 external keyboard, LED dot-matrix display circuit and some simple consisting of analog and digital circuits, transmission of information between patients and health care personnel can be achieved Simulation in the design of two wards each ward two beds in 0101/0102 0201/0202, each hospital bed has a button, when the patients when necessary, press the button, the display of the duty room to display in this patient ward number and bed number, health care workers press the "response" to cancel the current call. This system can provide a low cost, high efficiency, easy operation and easy installation and maintenance system for the hospital.
Keywords：MCU; Keyboard; Dot matrix; LED display; Calling system
