A kind of anti-backflow disposable drainage bag

Abstract

The invention relates to a disposable drainage bag for backflow prevention, which comprises a drainage tube joint mechanism, a drainage tube, a flow stop clamp, a hanging tube, a hanging belt, an anti-backflow sheet, a liquid storage bag and a liquid drainage device; the liquid storage bag is provided with The liquid inlet and the liquid outlet, the drainage tube passes through the liquid inlet and is fixed on the top of the liquid storage bag, the stop clip is fixed on the drainage tube, the drainage tube joint mechanism is fixed on the outer end of the drainage tube, and the drainage device passes through the liquid outlet It is fixed at the bottom of the liquid storage bag, and the hanging tube and hanging strap can be detachably fixed on the top of the liquid storage bag. The anti-reflux sheet includes the first counterflow sheet and the second counterflow sheet, and the first counterflow sheet is fixed on the second backflow sheet. Above the sheet, the first counterflow sheet and the second counterflow sheet are latex sheets with a conical structure, which can effectively prevent liquid diversion, and improve the connection structure of the drainage tube. It will slip or leak, which protects the health and safety of users in many ways.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable drainage bag for preventing reflux.
