单片机(6)还肩负有观察体温变化的任务。 SCM (6) also shoulder the task has observed temperature changes. 输液时的体温升高,反映了输液反应的发生,当一旦接通漏液探测器(31)的电路,漏液探测器(31)便将测得的温度信号送入单片机(6)的锁存器(44),一旦发生输液反应,造成体温升高,超过一定的阀值后,单片机(6)便向微机(2)报警,并同时发布要求输液泵(8)的步进电机(15)停止运行的命令,输液漏液探测器(31)能够精确地探测到体温微小的变化,杜绝事故的发生。 Elevated temperature infusion, reflecting the occurrence of infusion reactions, when the lock once the leak detector (31) circuit is turned on, the leak detector (31) put a measured temperature signal into the microcontroller (6) register (44), upon the occurrence of infusion reactions, resulting in fever, more than a certain threshold, the microcontroller (6) Bianxiang microcomputer (2) alarm, and also released infusion pumps (8) of the stepping motor (15 ) stops running the command, infusion leakage detector (31) can accurately detect small changes in body temperature, to prevent accidents.

参照图7,本实用新型单片机(6)的软件控制示例比较简单,如初始化→接受微机(2)传来的输液参数→给定硬件分频器(45)的脉冲频率→循环、等待定时器中断和分频器脉冲中断。 Referring to FIG 7, the present invention microcontroller (6) is relatively simple example of the control software, such as initializing the microcomputer accepts → (2) → transmitted infusion parameters given hardware divider (45) → pulse frequency cycles, waiting timer interrupts and interrupt pulse divider.

本实用新型的主程序是:计算本次控制字所在地址→从EPROM中读取控制字→将控制字送往输液泵(8)控制集成块8155A(40)的PC口→结束、返回。 The main program of the present invention are: The calculated address where the control word read from the EPROM → → control word is the control word sent to the infusion pump (8) control manifold 8155A (40) → PC port of ends and returns.

输液监控程序为:关中断→读取锁存器(44)值→①有漏液? Infusion monitoring procedures: Off Interrupt Latch is read → (44) → ① fluid leakage value? ②体温升高? ② body temperature? ③输液管内有空气? ③ air in the infusion tube? 如有,则:置硬件分频器频率为0,停止输液;如否,则:读取计数值→速度合要求? If so, then: the crossover frequency is 0, the hardware, the infusion is stopped; if not, then: → speed read the count value meets the requirement? 如是,则向微机(2)传送当前状态;如不是,则:调整硬件分频器(45)频率→向微机(2)传送当前状态→开中断、返回。 If so, the current state is transmitted to the microcomputer (2); if not, then: adjust the hardware divider (45) frequency → open → interrupt the current state of the transfer, return to the microcomputer (2).

上述硬件分频器脉冲中断优先级较低,定时器中断子程序优先级较高。 Pulse divider above hardware interrupt lower priority, the timer interrupt subroutine higher priority.
