Description

A New Chest Flushing and Drainage Tube

technical field

The utility model relates to the technical field of medical devices, in particular to a novel thoracic cavity flushing and drainage tube.

Background technique

At present, the method adopted for the closed chest flushing method is as follows: two tubes are used under image positioning, one is a flushing tube, which is inserted into the upper level of the abscess cavity, and is used to inject flushing fluid, and the other is a drainage tube, which is inserted into the abscess cavity. The lower part of the cavity is used to suck out the pus and other fluids washed down by the irrigation fluid. Its disadvantages are: two tubes are placed in different parts of the thoracic cavity. The two tubes are not only cumbersome to operate, but also cause greater surgical damage, which will increase the pain of the patient; Therefore, the two placed tubes cannot be guaranteed to be in the same cavity, and it is possible that the flushing fluid cannot be fully drained, resulting in aggravated spread of infection.

Now, there is also the structure of using the double cannula for drainage and flushing, but the existing double cannula for drainage and flushing also has its structural shortcomings, and can not really play the technical effect of thoroughly washing the pus and thoroughly draining it.

This shows that the above-mentioned existing pleural cavity irrigation and drainage tube obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently. How to create a new type of chest cavity irrigation drainage tube that can achieve a good drainage and irrigation effect has become a goal that needs to be improved in the current industry.

Utility model content

The technical problem to be solved by the utility model is to provide a novel thoracic cavity flushing and drainage tube, which can achieve good drainage and flushing effect simply and conveniently, thereby overcoming the existing deficiencies.

In order to solve the above technical problems, the utility model provides a thoracic irrigation and drainage tube, including a drainage tube and a flushing tube, the flushing tube is arranged on the inner wall of the drainage tube, and the end of the flushing tube is separated from the The end side wall is pierced, and the front end side wall of the drainage tube is provided with a drainage hole in a relative dislocation.

As an improvement of the utility model, the front end of the flushing pipe includes a free section.

As a further improvement, the free port of the free section protrudes from the front end of the drainage tube.

As a further improvement, the length of the free section is 60mm, and the distance between the root of the free section and the front port of the drainage tube is 20mm.

As a further improvement, the front port of the flushing tube is arranged flush with the front port of the drainage tube.

As a further improvement, four drainage holes are arranged on the side wall of the front end of the drainage tube in relative dislocation.

As a further improvement, the drainage hole is an oval hole, and the inner diameter of the oval hole is 6×8 mm.

As a further improvement, the drainage tube is made of silica gel, and the flushing tube is made of medical non-toxic transparent soft polyvinyl chloride plastic material, which is soft, tough and not easy to break.

As a further improvement, the inner diameter of the flushing pipe is 1.5 mm.

After adopting such design, the utility model has the following advantages at least:

1. The utility model sets the flushing tube and the drainage tube in the form of socketing, which is convenient for clinical use. Only one incision can realize the flushing and drainage of the cavity medium in the body, and reduce the trauma and blow of the operation on the human body. Relatively improve the safety of the operation, simplify the operation steps, and reduce the pain of the patient.

2. The utility model can better reduce the problem of blockage of the drainage tube by setting the drainage holes that are relatively dislocated, dense, and large in diameter, so that the drainage effect is more sufficient and more thorough.

3. The utility model sets a free section at the front end of the flushing tube, and extends out the front end of the drainage tube, so that the flushing liquid can more fully enter the cavity of the body, and then drain out after thorough flushing, so as to achieve a better drainage and flushing effect .

4. The utility model has the advantages of simple structure, low cost, remarkable effect and favorable promotion.

Detailed ways

Referring to the accompanying drawings 1 to 4, the utility model thoracic drainage tube includes a drainage tube 1 and a flushing tube 2, the flushing tube 2 is arranged on the inner wall of the drainage tube 1, and the inner diameter of the drainage tube 1 is 7 mm. The inner diameter of the flushing pipe 2 is 1.5 mm. The end of the irrigation tube 2 passes through the side wall of the end of the drainage tube 1, which facilitates the connection of the irrigation tube and the drainage tube to their connecting devices, and facilitates the separate operation and control of the irrigation tube and the drainage tube. In the flushing and drainage tube, the flushing tube is arranged inside the drainage tube, which is convenient for clinical use. Only one incision is needed to realize the flushing and drainage of the medium inside the thoracic cavity, thereby simplifying the operation steps and reducing the pain of the patient.

It should be pointed out that the front end referred to in this application document refers to the end of the irrigation and drainage tube that extends into the human body, and the end refers to the end of the irrigation and drainage tube that stays outside the human body. The advantageous formulation of the structure description should not be understood as any limitation on the structure. In addition, the drainage tube can also adopt existing drainage tubes of different specifications and sizes.

In this embodiment, drainage holes 3 are arranged on the side wall of the front end of the drainage tube 1 in a relative dislocation. Preferably, there are four drainage holes arranged in relative misalignment, as shown in FIGS. 2 and 3 . Specifically, the drainage hole 3 is oval, with a size of 6×8mm. The design of the drainage hole 3 can better reduce the blockage of the drainage tube, so that the drainage effect is more sufficient and more thorough.

Referring to accompanying drawings 1, 2 and 5, the front end of the flushing tube 2 in this embodiment includes a free section 21, and the free port of the free section 21 protrudes from the front end of the drainage tube 1, which is beneficial to improve the flushing effect.

In order to further improve the flushing effect of the flushing tube and achieve good cooperation with the drainage of the drainage tube, the free section of the flushing tube 2 starts to fork and free from the front port of the drainage tube 1 by 20 mm, and the length of the free section 21 is 60 mm. In this way, the setting effect of the free section of the flushing tube is to make the flushing liquid more fully enter the chest cavity in the body, and then drain out after the thorough flushing, so as to achieve a better flushing effect.

Certainly, as shown in accompanying drawings 6 and 7, the front end of the irrigation tube 2 can also be set not to be free, and then the part of the irrigation tube 2 inside the drainage tube 1 is connected to the inner wall of the drainage tube 1 . The front port of the flushing tube 2 is flush with the front port of the drainage tube 1 .

In order to facilitate the irrigation and drainage tube to enter the body without scratching the skin perforation, the drainage tube 1 is made of silica gel, and the irrigation tube 2 is made of medical non-toxic transparent soft polyvinyl chloride plastic.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Those skilled in the art may use the technical content disclosed above to make some simple modifications, equivalent changes or modifications. Within the protection scope of the present utility model.
