3、病人在危急時(shí)刻及時(shí)的聯(lián)系上醫(yī)生或者護(hù)士，從而得到及時(shí)的救治或看護(hù)。所以擁有一套功能完善的病床呼叫系統(tǒng)，對(duì)于一個(gè)提供高質(zhì)量服務(wù)的醫(yī)院來講，是非常重要的。這個(gè)設(shè)計(jì)所要求的整個(gè)呼叫系統(tǒng)由撥動(dòng)開關(guān)、控制電路、蜂鳴器、計(jì)時(shí)器、指示燈等幾個(gè)部分所組成，病人在身邊沒有醫(yī)生但卻需要護(hù)理的時(shí)候能夠做到及時(shí)的告知醫(yī)務(wù)人員，醫(yī)生也能夠通過該系統(tǒng)準(zhǔn)確的判斷出是哪個(gè)床位的病人需要護(hù)理。該系統(tǒng)最突出的一個(gè)優(yōu)點(diǎn)是具有優(yōu)先選擇功能，能夠在第一時(shí)間做到對(duì)最需要救助的人進(jìn)行幫助。在本課程設(shè)計(jì)所要求的病床呼叫系統(tǒng)中，若1號(hào)病人當(dāng)病人撥動(dòng)求助開關(guān)時(shí)呼叫，則數(shù)碼管顯示1號(hào)，同時(shí)對(duì)應(yīng)床位的LED燈亮，蜂鳴器發(fā)出響聲，三秒鐘之后，蜂鳴器停

4、止發(fā)聲。但是LED燈和數(shù)碼管仍然顯示，直到醫(yī)生或護(hù)士去到病房解除報(bào)警。由于蜂鳴器聲音比較刺耳，所以只讓蜂鳴器響三秒，三秒過后自動(dòng)停止，到下一次警報(bào)的時(shí)候再響。這樣可以保證醫(yī)院安靜的工作環(huán)境，使病人能夠更好的休息治療。本系統(tǒng)的優(yōu)先呼叫功能即當(dāng)優(yōu)先級(jí)較高的病床呼叫時(shí)，可以屏蔽其他病床的呼叫，若一號(hào)病床的優(yōu)先級(jí)最高，當(dāng)1號(hào)和2號(hào)病床同時(shí)呼叫或者1號(hào)晚于2號(hào)呼叫，數(shù)碼管只顯示1號(hào)，系統(tǒng)自動(dòng)屏蔽了2號(hào)的呼叫，只有當(dāng)1號(hào)解除警報(bào)時(shí)具有下一優(yōu)先級(jí)的病床才能呼叫，這樣只要把在出現(xiàn)情況的情況下最急需救助的病人放在優(yōu)先級(jí)最高的病床，就可以保證病人優(yōu)先得到治療。2設(shè)計(jì)原理及總體框圖根據(jù)設(shè)計(jì)要求，我們將設(shè)計(jì)分為幾個(gè)模
