Description
Technical field
This utility model relates to a kind of medical transfusion alarm device, relates in particular to a kind of infusion alarm.
Background technology
When hospital infuses; because patient is physical weakness, tired out often; can fall asleep in the time of usually can infusing; if unmanned the treatment; when the infusing medicine water droplet can cause backflow of blood to the greatest extent the time to tube for transfusion and cause danger; carry out alarm so the hospital that has has introduced when infusion alarm finishes to transfusion, thereby alleviated the safe condition of infusion process to a certain extent.Existing infusion alarm adopts laser to judge liquid level position more, and then judges whether dropping liquid is totally lost, and reports to the police then.Such product cost costliness is not easy to be generalized to all hospitals and uses.
Summary of the invention
This utility model provides a kind of infusion alarm, simplified structure, reduces cost.
In order to achieve the above object, this utility model is taked following technical scheme:
Infusion alarm comprises power supply and spring scale, and the pointer of spring scale is provided with movable contact spring, also is provided with static contact on the spring scale, and connect between movable contact spring and the static contact alarm, power supply and switch are parallel with the point contact type radio transmitting apparatus on the switch.
Infusion bottle is hung on the hook of spring scale, the other end of spring scale is fixed, the indicated transfusion empty bottle weight place of the pointer of spring scale is provided with static contact, along with being decreased in the infusion bottle dropping liquid gradually, the weight in the infusion bottle is totally lost, movable contact spring and static contact contact energized and alarm, alarm begins the alert notice nurse in time to be handled the patient, be emitted to the nurse station calling system by switch connection point contact type radio transmitting apparatus and by electromagnetic wave simultaneously, notify the nurse in time the patient to be handled.
This utility model is simple in structure, with low cost, easy to operate.
