In one form, the length of the extension tube is 2 to 3 times the outer diameter of the tube body.

The utility model has the advantages that:

1. compared with the existing equipment, the product does not have the part A, and blood clots are not easy to form;

2. the extension tube is arranged to reduce the needle puncture injury;

3. and a handheld part is also arranged at one end close to the first end head piece, so that the operation is convenient.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a first head piece of the present invention;

fig. 3 is a schematic diagram of a prior art product.

In the figure:

10 first end piece, 11 rubber piece, 12 CVC connecting end, 13 extending pipe, 14 connecting end, 20 pipe body, 21 handheld part and 30 second end piece.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figure 1, the T-shaped transfusion connecting pipe comprises a pipe body 20, a first end head piece 10 and a second end head piece 30 are respectively connected with two ends of the pipe body 20,

with reference to fig. 2, the first head 10 is a through structure, the tube 20 is connected to the upper end of the first head 10, and the tube 20 of the prior art (see fig. 3) is connected to the middle of the head, which results in a cavity in the upper part of the tube.

A connecting tube is shown in fig. 3, which is explained in comparison with the present invention, illustrating some of the problems of the prior art tube of fig. 3, wherein a section of the tube exists at the a site of the prior art, the existence of which easily causes blood to clot therein to form a blood clot; the tube body of the part B in the prior art is short, so that puncture is easily caused in the using process, and after the injection needle punctures from the rubber part 11, the needle tube is long, the part B is short, and the puncture is easily caused.

The first end piece 10 is provided with a connecting end 14, an extension pipe 13 and a CVC connecting end 12 in sequence from the head end to the tail end.

The pipe body 20 is connected to the side wall of the connecting end 14 and has a communication relationship with the side wall, and the pipe body 20 is communicated with the inside of the connecting end 14 through a hole in the side wall of the connecting end 14, but the pipe body and the connecting end are not limited to be produced separately and can also be formed integrally;

referring to fig. 2, the head end of the connecting end 14 is provided with a rubber member 11, wherein the rubber member 11 may be of an inner plug type or a sleeve type, as shown in fig. 2, the sleeve type also has an inner plug 111 in the middle, and the inner plug 111 is plugged in the upper port of the connecting end 14 when in use.

One way of providing the rubber member 11 is detachable.

The liquid can be injected from the rubber member 11 inwards by means of a syringe, which can pierce the rubber member 11.

When the rubber piece 11 is arranged at the connecting end 14, a connecting wound 22 of the connecting part of the pipe body 20 and the connecting end 14 is flush with the tail end of the rubber piece 11;

further, the inner plug 111 is flush with it, so that the connection end 14 has no cavity at its upper end, i.e. the part a in fig. 3 is not present, and the formation of blood clots is avoided.

The extension pipe 13 is a hard pipe, and the hard pipe is used for avoiding bending and is convenient to use.

The tail end of the second end head piece 30 is provided with an infusion apparatus connecting part.

The two ends of the pipe body 20 close to the first end head piece 10 and the second end head piece 30 are both provided with a handheld portion 21, the handheld portion 21 is also arranged at a position close to the first end head piece 10, so that the pipe body is more convenient to operate, and the existing product is only provided with one handheld portion 21.

The length of the extension pipe 13 is 2-3 times of the outer diameter of the pipe body 20, so that the length of the extension pipe 13 is more reasonable, and along with the change of the model of the pipe body 20, the length of the extension pipe 13 can be ensured to reduce the needle puncture injury to a certain extent.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. Which all fall within the protection scope of the utility model. The protection scheme of the utility model is based on the appended claims.
