Description

A kind of wound closure irrigation anti-clogging drainage tube

Technical field:

The utility model relates to the technical field of medical drainage tubes, in particular to an anti-clogging drainage tube for wound closure and irrigation.

Background technique:

Clinically, purulent infection of bone and joint requires the application of sufficient effective antibiotics throughout the body, complete removal of lesions and adequate drainage to speed up the closure of the abscess cavity. Closed lavage and negative pressure drainage are two tubes inserted into the wound after the lesions are cleared, one tube for lavage and one tube for drainage, the incision is completely closed, and an effective antibiotic solution containing a certain concentration of antibiotics is selected for continuous lavage and drainage. Drainage, in order to ensure the recovery and healing of the wound, the duration of lavage and drainage is longer, usually several weeks. In practice, due to the thick pus, impurities or flocs may be trapped, and there is also a small amount of wound tissue growth. When the fixed tissue is generated, the orifice of the drainage tube is easily blocked during drainage, and the flushing fluid can be injected smoothly but the drainage is not smooth. a great inconvenience. The patent number is ZL201520316239.X by adding a simple airbag device to the drainage tube, and blowing air into the drainage tube through the airbag device to prevent the drainage tube from being blocked. However, due to the large diameter and length of the drainage tube, the air blowing port of the airbag device It is only set at the front end of the drainage tube. Once the rear end of the drainage tube is blocked by the entry of larger particles or the deposition of impurities, blowing through the air bag can only remove the blockage of smaller particles in the front end of the drainage tube, but cannot remove the large particles at the rear end. Particulate blockage with limited removal.

Utility model content:

(1) Technical problems solved

The utility model aims to provide an anti-clogging drainage tube for wound closure irrigation, which solves the problem that the existing wound closure irrigation drainage tube can only clear the blockage of small particles at the front end of the drainage tube, and cannot clear the rear end of the drainage tube due to large particles or small particles. The problem of blockage caused by impurity deposition.

(2) Technical scheme:

In order to solve the above-mentioned technical problems, the present utility model adopts the following technical scheme: a wound closure lavage anti-blocking drainage tube, comprising an outer tube body and an air blowing tube, the head end of the outer tube body is provided with a number of drainage holes, the The head end of the blowing pipe extends into the outer pipe body and is arranged concentrically with the head end of the outer pipe body, the head end of the blowing pipe is provided with a blowing hole, and the tail end of the blowing pipe is arranged in the The balloon outside the tube body is connected, the balloon is provided with a one-way intake valve, and the air blowing pipe is provided with a one-way exhaust valve.

The drainage hole provided at the head end of the outer pipe body can isolate large particles from entering the outer pipe body. When the drainage hole is blocked, or the outer pipe body is blocked due to the deposition of particles, it can be blocked by pressing the The balloon is ventilated into the blowing pipe, and the blowing hole ejects gas to dredge the inside of the drainage hole and the outer pipe body, so as to ensure smooth drainage of the drainage hole and the outer pipe body. The one-way intake valve ensures that outside air enters the balloon, and the one-way exhaust valve can prevent the drainage fluid in the outer tube from flowing back into the balloon.

Further, an elastic sealing ring is provided at the connection where the air blowing pipe passes through the outer pipe body, and the elastic sealing ring can prevent leakage of drainage fluid at the connection between the air blowing pipe and the outer pipe body. The insufflation tube can be drawn and pulled through the balloon, so that the air insufflation tube can move in the outer tube body, which plays the role of dredging the pipeline and further prevents blockage in the outer tube body.

Further, the number of the drainage holes provided at the head end of the outer pipe body is not less than 8, and the diameter of the drainage holes is 1mm-3mm to ensure that large particles in the drainage liquid will not enter the outer pipe. inside the body.

Further, the positions of the air blowing holes correspond to the positions of the drainage holes, so as to ensure the effect of blowing and dredging the drainage holes through the air blowing holes.

(3) Beneficial effects:

Compared with the prior art, the beneficial effect of the present invention is: by arranging a number of drainage holes on the outer pipe body, and arranging a ventilating air blowing pipe in the outer pipe body, the large particles in the drainage liquid are prevented from entering the outer pipe body and causing it to occur. When the tail end is blocked, it can be dredged by blowing air, which can effectively prevent the drainage hole from being blocked. At the same time, the blowing pipe can also move in the outer pipe body to prevent the blockage caused by the deposition of impurities in the outer pipe body and ensure the smooth flow of the whole drainage.
