Abstract
A drainage bag relates to the technical field of medical apparatus, and comprises a bag body, a drainage tube and a liquid discharge pipe, wherein both the drainage tube and the liquid discharge pipe are arranged at the top end of the bag body and are communicated with the inner chamber of the bag body; a valve is arranged on the liquid discharge pipe; a ventilated film is arranged at the upper part on one side surface of the bag body; an anti-reflux device is arranged in the inner chamber of the bag body, and comprises two anti-reflux membranes which are arranged symmetrically and can be opened and closed; the outer surfaces at the upper parts of the anti-reflux membranes are in sealed connection with the inner surfaces at the upper parts of the front side surface and the rear side surface of the bag body respectively; and the opening of the drainage tube, which is inserted into the inner chamber of the bag body, is arranged between the upper parts of the anti-reflux membranes. The drainage bag is simple and reasonable in structure, safe and sanitary and can avoid reflux pollution, thereby being suitable for collecting body fluid, tissue transudation and the like.
Description
Technical field
This utility model relates to the medical devices technical field, the drainage bag of the various liquid of drain after particularly a kind of patient of being used for performs the operation.
Background technology
Drainage is a kind of measure of treating timely and effectively in clinical position, is usually used in surgical operation and critically ill patient, and structurally there is following defective in drainage bag at present commonly used: 1) occur the anti-stream of drain liquid easily and cause retrograde infection.2) gas of retention is prone to counter flowing in the drainage tube in the drainage bag, thereby makes the effect of drainage tube forfeiture syphon drainage.3) bleeder valve causes leakage easily in the drainage bag bottom.
Summary of the invention
This utility model purpose is that providing a kind of to above defective prevents that leakage, liquid from instead flowing, the drainage bag of gas reflux.
This utility model comprises bag, drainage tube, discharging tube, and said drainage tube and discharging tube all are located at the bag top, and is communicated with the bag inner chamber, on said discharging tube, is provided with valve; On the lateral top of said bag ventilated membrane is set; Be provided with anti-backflow device at said bag inner chamber, said anti-backflow device comprise symmetrically arranged two can open, closed anti-adverse current diaphragm; Said two diaphragm-operated outer surface of upper of anti-adverse current are tightly connected with the leading flank of bag, the upper inside surface of trailing flank respectively, and the opening that said drainage tube inserts the bag inner chamber is arranged between two diaphragm-operated tops of anti-adverse current.
This utility model is arranged on the bag top with discharging tube, prevents the appearance of the phenomenon of leakage.This utility model is provided with ventilated membrane, and balanced bag air pressure inside makes drain more smooth and easy.This utility model has added anti-adverse current diaphragm, and when drain liquid forward flow, anti-adverse current diaphragm opens, and drain liquid can pass through, and when drain liquid was reverse, anti-adverse current diaphragm abutted in together, the sealing inlet, thus guaranteed safe in utilization.Simple and reasonable, the safety and sanitation of this utility model can prevent that adverse current from polluting, and are applicable to body fluid, organize the collection of transudate etc.
The said bag of this utility model is provided with the drainage flow scale, the convenient observation and metering.
The top of the said bag of this utility model is provided with link, the convenient bag body overhang.
