Abstract
The invention discloses a device for monitoring the liquid level in an infusion apparatus Murphy's dropper. The device comprises a light transmitting device and a light receiving device, wherein the light transmitting device and the light receiving device are located on two sides of the Murphy's dropper and at the same horizontal height and arranged horizontally and correspondingly, a connecting line of the light transmitting device and the light receiving device deviates the axis of the Murphy's dropper, and the positions of the light transmitting device and the light receiving device correspond to a preset liquid level position in the Murphy's dropper. When light transmitting device transmits incidence light, the incidence light is parallel to a circular cross section of the Murphy's dropper and is subjected to twice refraction when passing through liquid in the Murphy's dropper, the light deviates from the connecting line of the light transmitting device and the light receiving device and accordingly cannot reaches to the light receiving device, and the liquid level does not descend to the preset position. When the liquid in the Murphy's dropper descends, the liquid level descends to the position under an incidence light path, the light receiving device receives the light transmitted by the light transmitting device and enables an alarm apparatus to give out an alarm, and accordingly the device confirms that the liquid required to drip is already used up, and medical change or needle withdrawal is needed.
