在病房输液过程中,有时由于医护人员较忙不能旁候,因此偶尔会发生液体输完后尚未发觉,以至造成意外(特别是昏迷病人及术后未清醒者等)。应用此报知器(见附图),无需医护人员旁候及耽心液体何时输完,从而减轻医护人员负担,提高工作效率,并保证输液安全。一、工作原理:利用液体重量与螺旋弹簧因液体重量的逐渐减少,弹簧张力回升,阴阳电极接触而发出信号(喇叭声、灯光等),告知液体将毕。二、使用说明:应用时将该器上端挂在输液架上,下端挂液体瓶,内放30～50毫升液体,此时扭动调节器使阴阳电极刚剐接触而发出信号。然后加入所需液体量(500～1,000毫升),此时弹簧受液体
During the infusions in the ward, sometimes the healthcare workers are too busy to wait. Occasionally, the liquid has not yet been found after it has been lost, resulting in accidents (especially unconscious patients and postoperative unconscious persons). Apply this notification device (see photo), no need for medical staff to wait and lose liquid when finished, thereby reducing the burden on health care workers, improve work efficiency and ensure the safety of infusion. First, the working principle: The use of liquid weight and coil springs due to the gradual reduction of liquid weight, spring tension rise, yin and yang electrode contact and signal (horn, light, etc.), inform the liquid will be completed. Second, the use of instructions: When the device is hanging on the top of the infusion rack, the bottom of the hanging liquid bottle, put 30 to 50 ml of liquid, then twist the regulator so that the yin and yang electrode just touch and send a signal. Then add the required amount of liquid (500 to 1,000 ml), at which point the spring is subject to liquid
