Description

Drainage tube capable of being quickly communicated

Technical Field

The utility model belongs to the technical field of the medical appliances technique and specifically relates to a drainage tube that can fast rethread.

Background

The drainage tube is a medical appliance for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. The drainage tube has various types and is applied to clinical urology surgery, thoracic surgery, general surgery, orthopedics department and other department nursing or operation. However, when any type of drainage tube is used, the problem of blockage caused by effusion, hematocele, solid particles and the like in the operation in the lumen during drainage often occurs, especially in the drainage of orthopedic spinal surgery, a large amount of blood clots and the like are generated at the operation part, so that blood flows out when an operator pulls out a part of the drainage tube every time, and the front port and the side hole of the drainage tube are almost completely blocked by the blood clots when the drainage tube is completely pulled out. When present clinical use's drainage tube takes place to block up, the mediation is more troublesome and consuming time, and in case the drainage is obstructed time overlength will cause operation position pressure too big, and orthopedics backbone operation position because the existence of spinal cord, so too big pressure can lead to the oppression of spinal cord, and then leads to two to advance palace decompression, the irreversible injury of spinal cord even. Therefore, there is a need for a drainage tube with improved drainage efficiency.

Chinese patent documents: CN202021140943.1, application date 2020.06.18, patent names: a drainage tube for spinal surgery. Disclosed is a drainage tube for spinal surgery, including a drainage tube main body and a support body; the main body of the drainage tube is provided with a main hole and a first side hole group; the main hole extends along the length direction of the drainage tube main body; the first side hole group comprises a plurality of first side holes which are uniformly distributed along the length extension direction of the side wall of the drainage tube main body, and the aperture of each first side hole is gradually reduced along the drainage direction; the support body is fixedly connected with the drainage tube main body, the inner wall of the support body self-main hole protrudes towards the central shaft direction of the drainage tube main body, and the height of the support body is smaller than the radius of the main hole.

Chinese patent documents: CN202020330892.2, application date 2020.03.17, patent names: a drainage tube used after spinal surgery. The drainage tube used after the spinal column operation comprises a drainage tube body, wherein an air bag is sleeved outside the drainage tube body, one end, far away from a human body cavity, of the air bag is provided with a connector used for connecting an injector, and the injector completes the operation of inflating or exhausting the air bag; the air bag is attached to the outer surface of the drainage tube body in a clinging manner in an air exhaust state and is in interference fit with the drainage tube body, and a gap exists between the air bag and the drainage tube body in an inflation state.

In the above patent document CN202021140943.1, a drainage tube for spinal surgery is adopted, in which a main hole and a first side hole set are provided on a main body of the drainage tube; the main hole extends along the length direction of the drainage tube main body; the first side hole group comprises a plurality of first side holes, the difference of drainage efficiency between the main hole and the first side holes is reduced by adjusting the aperture of the first side holes, the drainage uniformity of the main hole and the side holes is improved, the compression resistance and bending resistance of the drainage tube are enhanced by arranging the support body, and the possibility of SSEH occurrence is effectively reduced; in the drainage tube for use after spinal surgery in CN202020330892.2, an air bag is sleeved outside the drainage tube body, a connector for connecting an injector is arranged at one end of the air bag far from the body cavity, and the injector completes the operation of inflating or evacuating the air bag. But when a drainage tube is blocked in the tube cavity, the blocking object can be quickly discharged out of the tube, so that the drainage is smooth, the drainage efficiency is improved, the drainage tube is suitable for drainage in various operations, and the drainage tube which can be quickly communicated and avoids overlarge pressure of an operation part does not have related reports at present.

In summary, there is a need for a drainage tube capable of quickly discharging a blockage out of the tube when the blockage occurs in the lumen of the drainage tube, ensuring smooth drainage, improving drainage efficiency, being suitable for drainage in various operations, and avoiding too large pressure at the operation site.
