Description

A medical drainage tube

technical field

The utility model relates to a medical drainage tube, in particular to a drainage tube for draining intraperitoneal fluid, and belongs to the technical field of medical auxiliary equipment.

Background technique

After abdominal surgery, abdominal drainage tubes are commonly used to drain accumulated blood and fluid. At present, most of the commonly used drainage tubes in clinical practice are rubber circular tubes with uniform thickness, which has many inconveniences in use: when clinical medical staff perform drainage, they usually need to first form a negative pressure in the tube through a tool such as a balloon to make the abdominal cavity The effusion enters the drainage tube, and then the drainage is cumbersome; when there is a large amount of effusion in the abdominal cavity, the drainage speed cannot be controlled, and the patient is prone to discomfort due to the excessive drainage speed; when replacing the drainage bag for the patient, the medical staff Usually, it is necessary to clamp the drainage tube with clamps to block the drainage before replacing it, and the operation is cumbersome.

Utility model content

Aiming at the above defects in the prior art, the utility model provides a medical drainage tube which can control the drainage speed and is easy to operate.

The utility model is realized through the following technical scheme: a medical drainage tube, including a drainage hose with several drainage holes at the front end, the special feature is that the drainage output end of the drainage hose is provided with a flow control valve A branch pipe communicating with the lumen is provided on the pipeline between the flow control valve and the drainage hole, and a suction device is provided at the end of the branch pipe.

The branch pipe is produced integrally with the drainage hose.

In specific use, place the drainage hose on the affected area, pull the suction device, and generate a certain negative pressure in the tube. The effusion in the affected area enters the cavity of the drainage hose from the drainage hole on the drainage hose, and the flow control valve is opened. The drainage fluid is discharged from the drainage output end of the drainage hose through the flow control valve. When the drainage speed needs to be adjusted, the drainage speed can be adjusted by rotating the knob of the flow control valve.

The beneficial effects of the utility model are: the utility model has a simple structure, and by setting a flow control valve at the drainage output end of the drainage hose, the drainage speed can be conveniently controlled, and the patient's discomfort caused by too fast drainage speed can be effectively avoided; At the same time, it makes the drainage operation more convenient by arranging a branch pipe and a suction device on the drainage hose.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

In the figure: 1. flow control valve, 2. drainage hose, 3. drainage hole, 4. branch pipe, 5. suction device.

Detailed ways

Below by non-limiting embodiment and in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, a medical drainage tube includes a drainage hose 2 with several drainage holes 3 at the front end, and a flow control valve 1 is provided at the drainage output end of the drainage hose 2. The pipeline between 3 is provided with a branch pipe 4 communicating with its lumen, and the end of the branch pipe 4 is provided with a suction device 5 . In this embodiment, the drainage hose 1 and the branch pipe 4 are manufactured in one body, and the material thereof is silica gel. The flow control valve 1 can be a ball valve. The suction device 5 is a piston type suction structure.

Other parts of the present utility model adopt prior art, do not repeat them here.

The utility model has the advantages of simple structure and convenient operation, and can be widely used in abdominal cavity drainage.
