Disposable stop drip automatic alarm infusion set

Abstract

The invention provides a disposable automatic drop stopping alarming infusion apparatus. The disposable automatic drop stopping alarming infusion apparatus comprises a drip chamber with a cavity, an upper liquid tube, a lower liquid tube and a floater, wherein the upper liquid tube and the lower liquid tube are arranged on the upper portion and the lower portion of the drip chamber respectively, and the floater is arranged inside the cavity of the drip chamber. The disposable automatic drop stopping alarming infusion apparatus is characterized in that the portion, above the floater, inside the cavity of the drip chamber is provided with an acoustic generator, the acoustic generator comprises a seat body, the upper end and the lower end of the seat body are provided with openings, an acoustic cavity is arranged inside the seat body, a flow hole which is cut through from top to bottom is arranged outside the seat body, the portion, above the acoustic cavity, on the seat body is provided with an acoustic diaphragm seat, an acoustic hole is arranged inside the acoustic diaphragm seat, multiple through holes are arranged outside the acoustic diaphragm seat, the upper end of the acoustic hole is provided with an acoustic diaphragm, the lower end of the acoustic hole is communicated with the acoustic cavity, the multiple through holes are communicated with the flow hole arranged outside the acoustic cavity, and one side of the acoustic cavity is provided with an alarming device installing hole. When drop stopping occurs due to the fact that medicine liquid is run off or a needle is deviated during infusion, and non acoustic signal is transmitted to an alarming device, alarming is carried out. Meanwhile, the floater moves downward to close a liquid flowing channel, the infusion is stopped, and blood is prevented from returning. The disposable automatic drop stopping alarming infusion apparatus is free of poison and pollution, safe, reliable, practical, and capable of totally guaranteeing the infusion safety for a patient.
