Infusion alarming device

Abstract

The invention relates to an infusion alarming device which comprises a shell and a controller, wherein a circuit board, a trumpet, a direct-current electric source, an alarming lamp, a power switch and a liquid detection switch which are electrically connected with the circuit board are arranged in the controller; the circuit board, the trumpet, the direct-current electric source and the liquid detection switch are arranged in the shell, the alarming lamp and the power switch are arranged on a lateral plate of the shell, an inclined notch which is matched with the bottle neck of an infusion bottle is arranged at the upper end of the shell, the liquid detection switch consists of an infrared light-emitting diode and an infrared receiving diode which are respectively positioned at two sidesof the upper end of the notch, a through hole used for transmitting light is respectively arranged on the shell at the corresponding parts respectively between the upper end of the notch and the infrared light-emitting diode as well as between the upper end of the notch and the infrared receiving diode, an air pump electrically connected with the circuit board is arranged in the shell, an air outlet joint which is externally connected with an air inlet pipe of a disposable infusion device and internally connected with an air outlet of the air pump is arranged on the lateral plate of the shell,and the liquid detection switch controls the circuit board to realize aural and visual alarm as well as the on-off of the air pump. The device has high accuracy and stable performance.

Description

technical field [0001] The invention relates to a transfusion alarm device. Background technique [0002] At present, clinical infusion is mostly carried out by using the liquid level difference. The infusion bottle is hung on a bracket or on the wall. The high-hanging infusion bottle brings a lot of inconvenience to medical staff, patients, and accompanying staff. Especially the liquid medicine remaining situation in the infusion bottle) is difficult to predict accurately, can make patient (especially blind person), attendant's physical and mental anxiety and exhaustion, can't actively and actively cooperate with the work of medical staff. [0003] In order to improve the above-mentioned infusion methods, some monitoring devices have also appeared clinically, but they all have the defects of complicated structure, inconvenient operation and poor performance. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a tra...
