Description

A medical tee joint

technical field

The utility model relates to the field of medical equipment, in particular to a medical three-way joint used for connecting a drainage tube and a drainage bag. the

Background technique

During medical treatment, a drainage tube is usually used to drain various body fluids, and during drainage, the body fluids are drained to the drainage bag through the drainage tube. At present, since the commonly used drainage tubes are not equipped with joints of uniform style and specification when they leave the factory, and the joints between the drainage tube and the drainage bag need to be connected to each other, the temporary configuration of the joint is used to transition the connection between the drainage tube and the drainage bag. At this time, due to the difficulty in matching the pipe diameter between the joint and the interface of the drainage tube and the drainage bag, it is easy to cause the problems of weak connection and poor stability, and eventually lead to the disconnection of the connection between the drainage tube and the drainage bag interface when the patient turns over in normal activities, and the drainage fluid leaks out. Leakage increases the risk of wound infection, and also brings many problems to clinical nursing work. In addition, if the drainage fluid is viscous in clinical practice, the drainage effect will be affected, and it is usually necessary to flush or use central negative pressure suction, and the conventional straight-through drainage tube connector often cannot meet the needs of treatment. the

Utility model content

The purpose of this utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a medical three-way joint for connecting drainage tubes and drainage bags. The effective connection can meet the needs of flushing treatment. the

In order to achieve the above object, the utility model provides the following technical solutions:

A medical three-way joint, comprising a three-way pipe, the middle part of the three-way pipe is provided with a three-way valve, the inner wall of one of the interfaces of the three-way pipe is smooth, and the outer wall is pagoda-shaped; the other two of the three-way pipe The inner wall of each interface is pagoda-shaped, and the outer wall is smooth.

Among the above-mentioned medical tee joints, the interface with a smooth inner wall and a pagoda-shaped outer wall is the input interface; the two interfaces with a pagoda-shaped inner wall and a smooth outer wall are the output interfaces. Since the outer wall of the input interface is pagoda-shaped, it is convenient for drainage tubes of various diameters to be inserted; at the same time, the inner wall of the output interface is pagoda-shaped, which is convenient for the insertion of drainage bag interfaces of various types and sizes in clinical practice. the

In the above-mentioned medical three-way joint, safety caps are provided at the three joints of the three-way pipe to protect the joints.

In the above-mentioned medical three-way joint, the three-way pipe is made of transparent material, so that it is convenient to observe whether there is any foreign matter in the three-way pipe. the

In the above-mentioned medical three-way joint, the material for making the three-way pipe is polypropylene, which is a non-toxic, odorless, tasteless milky white high-crystal polymer with good heat resistance, and the products made therefrom can be used in Sterilize at a temperature above 100°C. the

Compared with the prior art, the utility model has the beneficial effects: the utility model is simple in structure, and the pagoda-shaped interface is convenient for connecting hoses of various diameters, and the connection is tight and firm, which can meet the clinical requirements of various types of drainage tubes and tubes. Effective connection between drainage bags. By adjusting the three-way valve, the three-way joint can achieve different drainage states, which can not only meet the central negative pressure, but also meet the needs of flushing treatment.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described. the

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, not to limit the utility model. the

Example 1

As shown in accompanying drawings 1, 2, and 3, the medical three-way joint of the present embodiment includes a three-way pipe 1, a three-way valve 2 is arranged in the middle of the three-way pipe 1, and the input interface of the three-way pipe 1 3. The inner wall is smooth, and the outer wall is pagoda-shaped; the inner wall of the other two output interfaces 4 of the three-way pipe 1 is pagoda-shaped, and the outer wall is smooth. Safety caps 5 are provided at the three interfaces of the three-way pipe.

As shown in Figure 4, the drainage tube 6 is connected to the drainage bag interface 7 through the three-way joint of this embodiment. Since the outer wall of the input interface 3 is pagoda-shaped, it is convenient to insert various drainage tubes 6 with a diameter of 3mm to 10mm. At the same time, the inner wall of the output interface 4 is pagoda-shaped, which is convenient to be closely connected with the drainage bag interface 7 of various types and sizes clinically, and the connection is tight and firm, which can effectively prevent wound infection of patients and reduce nursing work. By adjusting the three-way valve 2, the three-way joint can realize different drainage states, which can satisfy both central negative pressure and flushing treatment needs. the
