CN2703531Y - Acoustic-light automatic alarm for infusion of hanging bottle - Google Patents

Abstract

The utility model discloses an acoustic-light automatic alarm for infusion of hanging bottles used for intravenous injection for human bodies. An alarm which is composed of a buzzer 1, a transistor T, an acoustic integrated circuit module A and an LED (Light Emitting Diode) D is arranged on a hanging net bottle holder 2. A light sensitive element R1 or an infrared light emitting source 3 is assembled on the outer side of a medical liquid bottle 5. When fluid infusion begins, a power switch K is switched on; as the medical liquid level in the medical liquid bottle 5 is high at this time, the light emitted from the infrared light emitting source 3 can not be received by the light sensitive element R1, so the transistor T is in off-state, the LED D does not emit light and the buzzer 1 does not gives out an alarm. As the fluid infusion goes on, when the medical liquid level in the medical liquid bottle 5 falls to a certain point, the light emitted from the infrared light emitting source 3 can just be reflected by the liquid level onto the light sensitive element R1; as the light sensitive element R1 receives light, the resistor becomes small, so the transistor T is switched on, the acoustic integrated circuit module A works, the buzzer 1 give out sound to alarm, and the LED D emits light. The utility model can be widely used in hospitals or other medical institutions.
