The following describes the control principle of the single-chip microcomputer:
(1)预计出输液所需时间:输液前由护士通过键盘向输液报警器输入输液液体的总体积V,光电门传感器位于输液管粗管处,测出液体单位时间滴下的滴数n,在通过调查收集数据后计算平均值得到每一滴液体的体积v。单片机预计输液的所需时间t=V/nv;并通过LCD显示屏将所得结果进行显示。(1) Estimated time required for infusion: before the infusion, the nurse inputs the total volume V of the infusion liquid to the infusion alarm through the keyboard. The volume v of each drop of liquid is obtained by calculating the average value after collecting data through investigation. The single-chip computer predicts the time required for infusion t=V/nv; and displays the obtained results through the LCD display.
(2)血液回流报警功能:光电门传感器测出单位时间滴下的滴数n,通过相应计算得到液体滴下速度v;单片机进行逻辑关系判断:首先,重力传感器所测得重量未小于报警重量M1,其次,光电门传感器已在5秒内检测不到药液滴下;最后,若同时满足以上两个条件,输液报警器自带蜂鸣器会发出警告,提示患者血液回流。(2) Blood backflow alarm function: the photoelectric gate sensor measures the number of drops per unit time n, and the liquid dripping speed v is obtained through corresponding calculation; the single-chip microcomputer performs logic relationship judgment: first, the weight measured by the gravity sensor is not less than the alarm weight M1, Secondly, the photogate sensor has not detected the dripping of the medicine within 5 seconds; finally, if the above two conditions are met at the same time, the buzzer of the infusion alarm will give a warning, prompting the patient to return blood.
(3)输液完毕即时报警功能:光电门传感器测出单位时间滴下的滴数n,通过相应计算得到液体滴下速度v;单片机进行逻辑关系判断:首先、重力传感器所测得重量小于报警重量M1,其次、光电门传感器检测液体滴下速度小于报警速度v1且液体的体积小于V1;如果满足上述条件,输液报警器向护士台发出特定频率的无线信号,护士台接收器接收信号,并根据不同频率语音提示特定床位需要换液,并且蜂鸣器会发出警报提醒病人注意。(3) Immediate alarm function after infusion: the photoelectric gate sensor measures the number of drops per unit time n, and the liquid dripping speed v is obtained through corresponding calculation; the single-chip microcomputer performs logical relationship judgment: first, the weight measured by the gravity sensor is less than the alarm weight M1, Secondly, the photoelectric gate sensor detects that the dripping speed of the liquid is less than the alarm speed v1 and the volume of the liquid is less than V1; if the above conditions are met, the infusion alarm sends a wireless signal of a specific frequency to the nurse's desk, and the receiver of the nurse's desk receives the signal, and according to the different frequency voice Prompt that a specific bed needs to be replaced, and the buzzer will sound an alarm to remind the patient to pay attention.
(4)药液即时加热功能:由温度传感器得到输液液体的温度t1;单片机进行逻辑关系判断:t1小于输液液体人体最适温度t2;如果条件满足时,启动输液加热器,对液体进行加热;当药液温度达到t2时,加热停止。(4) Immediate heating function of the liquid medicine: the temperature t1 of the infusion liquid is obtained by the temperature sensor; the single-chip microcomputer performs logical relationship judgment: t1 is less than the optimum temperature t2 of the human body of the infusion liquid; if the condition is met, the infusion heater is started to heat the liquid; When the liquid temperature reaches t2, the heating stops.
