Description

A visualized double-lumen drainage tube with double anti-clogging and pre-installed hidden flushing tube

technical field

The utility model relates to the technical field of medical equipment, in particular to a developable double-cavity drainage tube with double anti-clogging and preset hidden flushing tubes.

Background technique

After surgery on the abdomen, pelvis, thoracic cavity, and limbs, indwelling drainage tubes is extremely important as a treatment and preventive measure. It is excreted from the body and has the function of monitoring postoperative bleeding and gastrointestinal fistula. In addition, in the event of postoperative infection in the surgical area, two drainage tubes can be placed side by side or a double-lumen drainage tube can be used to achieve irrigation and drainage.

At present, the drainage tubes commonly used in clinical practice are often blocked by tissue, blood clots or viscous pus, etc., which cannot lead out the fluid in a timely and smooth manner, which affects the monitoring of postoperative complications and increases the possibility of postoperative fever Sexuality, prolonging the application time of antibiotics, and even requiring invasive operations such as puncture to drain fluid, increasing patient trauma and medical expenses. When it is suspected that the drainage tube is blocked, doctors often try to rotate, pull out and insert the drainage tube outside the body, so as to separate the drainage tube mouth from the insert and dredge it. However, the success rate of this attempt is low and it may scratch blood vessels and cause complications such as bleeding, so it has certain risks.

At present, several patents have designed drainage tubes with anti-clogging function: patent document CN214970849U discloses a kind of anti-clogging drainage tube, which seems to have the effect of avoiding drainage tube blockage, but the structure is complicated and the use is cumbersome, especially in laparoscopic surgery. It is inconvenient to apply in the middle of the country, and the clinical transformation value is limited. Patent document CN211096938U discloses a wound closure lavage anti-clogging drainage tube intended to dredge the drainage tube by means of balloon blowing, but directly injecting air into the surgical area is difficult to absorb and may bring in contaminating bacteria.

In summary, the existing drainage tubes have deficiencies in the prevention of blockage, effective dredging after blockage, flushing of the surgical area, and compatibility with laparoscopic surgery, etc., and there is a large room for improvement. After the operation, there is an urgent need for a double-cavity drainage tube that can more effectively prevent blockage, can effectively dredge after blockage, and has the function of rinsing the surgical area.

For this reason, we propose a dual-lumen drainage tube with double anti-clogging and pre-installed hidden irrigation tube.

Preferably, the end of the irrigation tube implanting groove close to the outer end of the drainage tube is open and sealed with a protective film.

Preferably, the tip of the flushing tube is a soft tapered opening.

Preferably, the outer end of the flushing tube can be connected to a commonly used clinical syringe or infusion set.

Preferably, the surface of the drainage tube is provided with a development scale line.

Preferably, the inner end of the drainage tube can be placed into an operation area in the body.

Preferably, the outer end of the drainage tube can be connected with a drainage bag or a drainage bottle.

Compared with the prior art, the beneficial effects of the utility model are:

1. The wave-shaped orifice design at the end of the body and the pre-installed flushing tube can double reduce the plugging rate of the postoperative drainage tube, which may reduce the use time of antibiotics and re-puncture rate, and reduce medical expenses;

2. When infection in the surgical area or blockage of the drainage tube occurs, timely dredging and effective flushing of the drainage tube can be realized;

3. There is no bifurcation in the tube body, which is convenient for the placement operation of the drainage tube after laparoscopic minimally invasive surgery, and the applicable scene is wider;

4. The device has a visible scale line, and the drainage tube can be positioned through imaging examination after surgery, which has a quantitative guiding effect on the length of the retrograde tube for special operations such as pancreatic surgery;

5. As a disposable medical consumable, the device has a simple structure but multiple functions, which is conducive to saving medical expenses and reducing medical burden.
