Description

a drainage tube

technical field

The utility model relates to the field of medical supplies, in particular to a drainage tube.

Background technique

There are many types of surgical drainage tubes used clinically, some are used for catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, and biliary tract. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing.

However, most of the current drainage tubes do not have the function of stretching, and cannot be applied to drainage at various depths.

Utility model content

In order to overcome the shortcomings of the background technology, the utility model provides a drainage tube, which mainly solves the problem that most of the current drainage tubes do not have the function of contraction and cannot be applied to drainage at various depths.

The technical scheme adopted in the utility model is:

A drainage tube, comprising a main tube, one end of the main tube is provided with a drainage hole, and the other end is provided with a drug feeding tube and a drainage tube communicating with the main tube, and the drug feeding tube is provided with a valve for opening and closing the drug feeding tube. The middle end of the main pipe is provided with a telescopic part, and a plurality of pipe wings are arranged outside the telescopic part, the upper end surface of the pipe wing is provided with a block, and the lower end surface of the pipe wing is provided with a block for locking with the block. Connect to the matching card slot.

The beneficial effects of the utility model are: the utility model provides a drainage tube, when it needs to be contracted, the blocks and slots of the adjacent tube wings can be engaged together, the drainage tube can be shortened, the structure is simple, and it is easy to use .

FIG. 2 is an enlarged schematic view of FIG. 1A .

FIG. 3 is an enlarged schematic view of FIG. 1B .

Detailed ways

The utility model is further described below in conjunction with the accompanying drawings: as shown in the figure, a drainage tube includes a main tube 1, one end of the main tube is provided with a drainage hole 11, and the other end is provided with a medicine feeding tube 2 and a tube connected to the main tube. Drainage tube 3, the tube clamp 25 for opening and closing the drug tube is provided on the tube, the middle end of the main pipe 1 is provided with a telescopic part 12, and a plurality of tube wings 13 are arranged outside the telescopic part 12, The upper end surface of the tube wing 13 is provided with a clamping block 131 , and the lower end surface of the tube wing 13 is provided with a clamping groove 132 for snap-fitting with the clamping block. When the main tube needs to be shortened, the adjacent tube wing blocks and slots can be engaged to shorten the drainage tube. The structure is simple and easy to use. As the preferred telescopic part, it can be made of bellows, which is easy to use and not easy to damage Of course, a through tube made of soft material can also be used here. In addition, there is a drug feeding tube and a drainage tube, which can separate the drainage from the drug feeding, which is more convenient to use. When the drug feeding is not needed, the tube can be The medicine feeding tube can be closed by clipping, and it can also be realized by tying it up with a rope.

In this embodiment, as shown in the figure, the telescopic part 12 is a bellows.

In this embodiment, as shown in the figure, the main pipe 1 , the medicine feeding tube 2 and the drainage tube 3 are arranged in a Y shape.

In this embodiment, as shown in the figure, the drug inlet tube 2 is provided with an anti-blocking air bag 24, and the anti-blocking air bag 24 is correspondingly provided at the rear end of the tube clamp. The anti-blocking air bag is made of elastic materials, such as rubber, silicone, etc., which can be pressed to open slightly blocked pipelines, which is more convenient to use.

In this embodiment, as shown in the figure, the inner wall of the drainage tube is provided with a long petal 22 and a short petal 23, one end of the long petal is arranged on the inner wall of the drainage tube, and the other end extends toward the outlet of the drainage tube , the long petal is located outside the short petal. Further, when the pressure in the body is low and the drainage fluid flows back to the position of the long valve 22, the long valve 22 is pushed backward to partially overlap the short valve 23, and the drainage tube is closed to avoid backflow.

In this embodiment, as shown in the figure, a scale 19 is also provided on the main pipe. It is convenient to observe the depth of penetration, and the use effect is better.

The embodiments should not be regarded as limiting the utility model, but any improvement based on the spirit of the utility model should be within the protection scope of the utility model.
