一、作品简介使用“医疗用输液换药告知器”时,当药液还剩三、五分钟就要输完时,它会发出警示声,提醒家人或护士注意。这款作品使用操作简单,制作过程不繁杂,制作成本也不高。它适用于用塑料药液瓶输液的情况,对玻璃药液瓶不太敏感。二、作品工作原理“医疗用输液换药告知器”的核心器件是能够检测几毫米距离内有无液体存在的电容式传感器。电容式传感器内部前端是一个开 First, the introduction of the work Use “Medical infusion modifier ”, when the liquid left three to five minutes will lose, it will issue a warning sound to remind family or nurses attention. This works easy to use, the production process is not complicated, the production cost is not high. It applies to the case of plastic liquid bottle infusion, the glass liquid bottle is not very sensitive. Second, the work works “Medical infusion modifier ” the core device is able to detect the presence of a few millimeters of liquid capacitance sensor. The internal front of the capacitive sensor is open
