Description

Medical drainage connection tube

technical field

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

Background technique

Clinically, the main purpose of the drainage tube is to drain the blood, exudate, and transudate in the body cavity (cranial cavity, chest cavity, and abdominal cavity) to the outside of the body, so as to reduce the pressure in the cavity, prevent infection, and promote recovery. Purpose. However, clinically, due to different drainage sites and different ages of patients, the required drainage tube specifications are different, leading to one: the connection between the drainage tube and the drainage bag is not tight enough, and it is prone to fall off, infection, and even death due to positive pressure in the cavity; Two: the length of the drainage tube is fixed, and for some patients, it is too long to achieve the purpose of drainage, and it is too short to easily fall off. There is an urgent need to design a multifunctional flexible medical drainage connecting tube to solve the above clinical confusion, treat patients and promote health.

Utility model content

Aiming at the deficiencies of the prior art, the utility model proposes a medical drainage connecting tube, which has an ingenious structure and is easy to operate.

In order to achieve the purpose of the above utility model, the utility model provides the following technical solutions: a medical drainage connection tube, including a puncture needle, a puncture connection tube and a drainage bag, the tail end of the puncture needle is provided with a threaded interface, and one end of the puncture connection tube is It is connected with the threaded interface, and the other end is plugged and movably connected with the outlet of the drainage bag.

Further, the middle section of the puncture connecting tube is a compressed tube structure.

Further, the other end of the puncture connecting tube is provided with a sterile cap.

Further, the other end of the puncture connecting tube is connected with a cone-shaped catheter, the tapered tip of the cone-shaped catheter is a closed end, the front side wall is provided with a small hole, and the outer wall is covered with a retractable intermediate body. The outer wall of the intermediate body is covered with a deformable shell; the drainage bag is connected to the shell in a plug-in type.

Further, the conical catheter is threadedly connected to the puncture connecting tube.

Further, the diameter of the puncture connecting tube is not less than three times the diameter of the puncture needle.

Compared with the prior art, the utility model has the following advantages: the structure of the drainage tube is formed by a multi-section connection method, the connection is good, and it is not easy to fall off and pollute, and the length is adjustable, which is convenient to use, easy to operate, safe and practical.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model medical drainage connecting pipe;

Fig. 2 is another kind of structural representation of the utility model;

Fig. 3 is a schematic diagram of the structure among the conical conduit, the intermediate body and the shell in Fig. 2 .

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.

As shown in Figure 1, a medical drainage connection tube includes a puncture needle 1, a puncture connection tube 2 and a drainage bag 3, the tail end of the puncture needle 1 is provided with a threaded interface 11, one end of the puncture connection tube 2 is connected to The threaded interface 11 is connected, and the other end is connected with the outlet of the drainage bag 3 in a plug-in type.

The middle section of the puncture connecting pipe 2 is a compression pipe structure 21, which can be stretched axially according to the needs of use, so as to achieve the purpose of adjustable length. One end connected with the drainage bag 3 is provided with a sterile cap 22, and the sterile cap 22 is opened only when the drainage bag 3 is connected with the puncture connecting tube 2, which is safe and hygienic to use.

Another medical drainage connecting tube as shown in Fig. 2 is the same as the structure of the above medical drainage connecting tube except for the following content.

One end that punctures connecting pipe 2 is connected with drainage bag is connected with conical conduit 4, as shown in Figure 3, the conical tip front end of described conical conduit 4 is a closed end, and front side wall is provided with aperture 41, and conical conduit The outer wall of 4 is covered with a stretchable intermediate body 5, and the outer wall of the intermediate body 5 is covered with a deformable shell 6; the drainage bag 3 is connected to the shell 6 in a plug-in manner. The cone catheter 4 is threadedly connected to the puncture connecting pipe 2 .

When the drainage bag 3 is inserted, the plug part of the drainage bag 3 squeezes the intermediate body 5, and at the same time squeezes the housing 6 to both sides; while the intermediate body 5 is compressed axially, and the radial expansion makes the housing 6 expand, which is convenient The plug of the drainage bag 3 enters until it is connected with the small hole 41 at the front end of the cone catheter 4 .

In the above two structures, the diameter of the puncture connecting tube 2 is not less than three times the diameter of the puncture needle 1 .

In the above two structures, PVC is used as raw material except for the following parts, which have the advantages of excellent comprehensive physical and mechanical properties, low price, and simple production process.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
