CN2322619Y - Double balloon drainage-tube - Google Patents

Abstract

The utility model relates to a double balloon drainage-tube. On one end of the silastic tube, the external circumference of the tube is sheathed with two tightly sealed balloons which have a proper spacing distance away from the external circumference of the tube. Each inner cavity of the balloon is communicated with a gas injection duct which hermetically enters the orifice of the silastic tube and hermetically threads out of the tube wall of the other end of the tube. Bulkheads are respectively mounted on the tail ends of the two gas injection ducts, and a junction pipe is arranged in the orifice of the tail end of the silastic tube. Near the balloon, the tube wall of the silastic tube is alternately provided with at least two side holes which have an interval in which a balloon is arranged. The utility model uses the inflation of the balloons to push off the intestinal canal or other organizations that block around the drainage-tube, which keeps the drainage-tube unlocked and avoids the easily happened complication as dropsy, affection, bleeding and intestinal adhesion after the operation on the chest and abdominal cavity.

Description

Two air bag drainage tubes

This utility model relates to the surgical operation medical instruments, and concrete is a kind of pair of air bag drainage tube.

At medical surgery breast, abdominal postoperative, need carry out drain with drainage tube, there is following shortcoming in prior art: (1) generator tube week tissue obstruction drainage tube easily causes inadequate drainage, causes breast, seroperitoneum, infects; (2) drainage tube continues to contact with intestinal tube, can cause bleeding, complication such as intestinal fistula, intestinal adhesion.

The purpose of this utility model provides a kind of pair of air bag drainage tube, the intestinal tube or its hetero-organization that utilize airbag aeration will be jammed in the drainage tube circumference are pushed open, keep drainage tube unimpeded, hydrops, the infection and hemorrhage of avoiding breast, abdominal postoperative to be prone to, complication such as intestinal adhesion.

The purpose of this utility model is achieved in that

A kind of pair of air bag drainage tube, its main body is the silicone rubber tube of a hollow, it is characterized in that:

A. at an end of silicone rubber tube, the suitable distance of spacer is set with the air bag of two sealings on the pipe excircle, each air bag inner chamber respectively is communicated with a gas injection conduit, the tube wall that this gas injection conduit passes silicone rubber tube hermetically enters pore, hold tube wall to pass hermetically in addition from silicone rubber tube, tail end at this two gas injections conduit respectively is equipped with plug, in the tail end pore of silicone rubber tube junction block is housed;

B. on tube wall, be provided with at least two side openings, be arranged between two air bags respectively and the outer end of one of them air bag near the silicone rubber tube of air bag.

During enforcement, the diameter of described side opening is less than 1/3 of the silicone rubber tube circumferential length.

This utility model has following actively useful effect:

Behind the two air bag drainage tubes of storing, every inflation in 3 hours, venting once, gas injection rate 20-60ml, inflation was kept 5-10 minute, can push open being jammed in drainage tube intestinal tube or other tissue on every side behind two airbag aerations, kept drainage tube unimpeded.This pipe is compared with existing drainage tube and is had the following advantages:

(1) can avoid managing week tissue and stop up that inadequate drainage forms pleural effusions and ascites, infection due to the drainage tube;

(2) effectively prevent because drainage tube and intestinal tube continue to contact complication such as cause hemorrhage, intestinal fistula, intestinal adhesion, be applicable to breast, abdominal postoperative drain.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is a profile sketch map of the present utility model, the air bag unaerated;

The same Fig. 1 of Fig. 2 is inflated condition;

Fig. 3 is the axial parting view of Fig. 2.

Of the present utility model pair of air bag drainage tube, its main body are the silicone rubber tube 1 of a hollow, please refer to Fig. 1 Fig. 2 Fig. 3.

A. at an end of silicone rubber tube, the suitable distance of spacing is set with the air bag 2 and 3 of two sealings on the pipe excircle, each air bag inner chamber respectively is communicated with a gas injection conduit 4 and 5, this gas injection conduit passes the tube wall inlet pipe hole of silicone rubber tube hermetically, hold tube wall to pass hermetically in addition from silicone rubber tube, tail end at this two gas injections conduit respectively is equipped with plug 6 and 7, in the tail end pore of silicone rubber tube junction block 8 is housed;

B. on the tube wall near the silicone rubber tube of air bag, air bag is provided with at least two side openings 9 and 10 at interval, and described side opening also can be more than 2 during enforcement.During enforcement, described side opening 9 and 10 diameter should be less than 1/3 of silicone rubber tube circumferential lengths.During enforcement, the plug 6 of described two gas injection tail end of conduit and 7 can be distinguished with different colours.

Claims (2)

1. two air bag drainage tube, its main body is the silicone rubber tube of a hollow, it is characterized in that:

A. at an end of silicone rubber tube, the suitable distance of spacer is set with the air bag of two sealings on the pipe excircle, each air bag inner chamber respectively is communicated with a gas injection conduit, the tube wall that this gas injection conduit passes silicone rubber tube hermetically enters pore, hold tube wall to pass hermetically in addition from silicone rubber tube, tail end at this two gas injections conduit respectively is equipped with plug, and junction block is housed in the tail end pore of silicone rubber tube:

B. on tube wall, be provided with at least two side openings, be arranged between two air bags respectively and the outer end of one of them air bag near the silicone rubber tube of air bag.

2. as claimed in claim 1 pair of air bag drainage tube, it is characterized in that: the diameter of described side opening is less than 1/3 of the silicone rubber tube circumferential length.
