Description

Disposable drainage bag

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of drainage bag.

Background technology

In the prior art, the drainage bag that a kind of anti-adverse current is arranged, the drain that it is mainly used in patient's body fluid or organizes transudate, by drainage catheter body fluid is drained in the drainage bag during drain, after drainage bag is full, can through liquid outlet body fluid be discharged from the drainage bag bottom, existing drainage bag, comprise the bag of making by the identical thin film of two plate shapes, the periphery of two thin film links together, top at bag is connected with the inlet of feed tube, the bottom of bag is provided with liquid outlet, and described bag high inside is provided with two soft catch between two thin film, and the end opening of catch abuts in together mutually, the inlet of described feed tube is arranged between two catch, and the top of catch and dual-side and thin film periphery are bonded together.This device in use, when body fluid enters drainage bag from inlet, at first enter between the two softish catch, and flow between two thin film along the gap between the catch, between two thin film, store, after drainage bag is full, can be from the liquid outlet emptying of bottom, after drainage bag is finished using, take off drainage bag, may also have body fluid in the drainage bag this moment, and when drainage bag was kept flat or is inverted, body fluid had adverse current trend in the drainage bag, can order about two catch abuts in together, the sealing inlet, body fluid can not oppositely flow out in the drainage bag, has guaranteed the safety and sanitation of using.Its weak point is: this drainage bag because the catch width is bigger, causes the catch consumptive material more during fabrication, and is economical inadequately; In addition, because the composition surface broad between two catch causes partially sealed not sternly easily, the probability of anastasis is still bigger.

The utility model content

The purpose of this utility model provides a kind of disposable drainage bag, make in the drainage bag body fluid keep not can the prerequisite of adverse current under, can also reduce manufacturing cost.

The purpose of this utility model is achieved in that disposable drainage bag, comprise the hollow bag of making by the identical thin film of two plate shapes, the periphery of two thin film bonds together, the top of bag is provided with feed tube, the bottom of bag is provided with liquid outlet, described bag high inside is provided with softish pipe box between two thin film, the pipe box upper end is enclosed within on the feed tube, the end opening of pipe box is flat fits together the last bottom of pipe box, and pipe box is suitable for reading, be tightly connected between feed tube periphery and the bag.

When this utility model uses, can body fluid be drained in the drainage bag by feed tube, when body fluid enters drainage bag from inlet, at first enter in the pipe box, flow between two thin film along pipe box again, and be stored between two thin film, after drainage bag is full, can be from the liquid outlet emptying of bottom, when the drainage bag that has liquid was kept flat or is inverted, body fluid had adverse current trend in the drainage bag, the end opening of pipe box fits together, can seal inlet, body fluid can not oppositely flow out in the drainage bag, has guaranteed the safety and sanitation of using.Compared with prior art, this utility model consumptive material is few, has saved resource, has reduced production cost; Simultaneously, because the composition surface of pipe box end opening is narrow, anti-adverse current better effects if is used safety and sanitation more, can prevent that the anastasis in the drainage bag from polluting, and this utility model can be used for body fluid, organize the collection of transudate etc.

Hang for convenient, described bag top is provided with lanyard.

Description of drawings

Fig. 1 is this utility model structural representation.

Fig. 2 is that the A-A of Fig. 1 is to view.

Wherein, 1 feed tube, 2 pipe boxes, 3 bags, 3a, 3b thin film, 4 liquid outlets, 5 lanyards.

The specific embodiment

As Fig. 1 and 2, be disposable drainage bag, comprise by the identical thin film 3a of two plate shapes, bag 3 that 3b makes, the periphery of two thin film 3a, 3b links together, the top of bag 3 is connected with feed tube 1, the bottom of bag 3 is provided with liquid outlet 4, the high inside of bag 3 is provided with softish pipe box 2 between two thin film, pipe box 2 suitable for reading being enclosed within on the feed tube 1, the end opening of pipe box 2 is flat fits together the last bottom of pipe box, be tightly connected between the periphery of suitable for reading, the feed tube 1 of pipe box 2 and the bag 3, bag top also is provided with lanyard 5.Above-mentioned thin film 3a, 3b and pipe box 2 all can be made by macromolecular materials such as polyethylene, polrvinyl chloride, and hot pressing is bonded together between the periphery of suitable for reading, the feed tube 1 of pipe box 2 and the bag 3.

During use, can body fluid be drained in the drainage bag by feed tube 1, body fluid flow between two thin film 3a, the 3b through sleeve pipe 2, and be stored between two thin film 3a, the 3b, after drainage bag is full, can be from liquid outlet 4 emptying of bottom, after drainage bag is finished using, take off drainage bag, may also have body fluid in the drainage bag this moment, when drainage bag is kept flat or is inverted, body fluid has adverse current trend in the drainage bag, and sleeve pipe 2 end openings fit together, sealing feed tube 1, body fluid can not oppositely flow out in the drainage bag, has guaranteed the safety and sanitation of using.

Claims (2)

1, disposable drainage bag, comprise the hollow bag of making by the identical thin film of two plate shapes, the periphery of two thin film bonds together, the top of bag is provided with feed tube, the bottom of bag is provided with liquid outlet, it is characterized in that: described bag high inside is provided with softish pipe box between two thin film, and the pipe box upper end is enclosed within on the feed tube, the end opening of pipe box is flat fits together the last bottom of pipe box, and pipe box is suitable for reading, be tightly connected between feed tube periphery and the bag.
