Abstract

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a tip transfusion harbor, including injection seat and pipe, the front end of injection seat is connected with the pipe, the structure of the head end of pipe is most advanced, most advanced for the slope is most advanced, and inclination is 40-50. When the infusion port is implanted, the central vein can be directly inserted without secondary cutting.

Description

Tip transfusion port

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a tip transfusion harbor.

Background

The transfusion port is a venous transfusion device which can be completely implanted under the skin and left in the body for a long time, can be used for the treatments of medicine infusion, fluid infusion, nutrition support, blood transfusion and the like, and can also be used for blood sample collection. The transfusion channel can be established by using the atraumatic needle to puncture the transfusion port, so that the pain and difficulty of repeated venipuncture are reduced.

The common structure of the infusion port existing in the market at present comprises a catheter part with a head end positioned in the superior vena cava and an injection seat embedded under the skin, wherein the head end structure is a flat head and is suitable for central venipuncture and infusion port implantation, as shown in figure 1. Clinically, infusion port implantation except central venipuncture, can also open through central vein and carry out infusion port implantation, when adopting central venous blood vessel to open and plant, because the bore is less when the vascular is opened, need cut the blunt end into the tip, the in-process of cutting moreover probably sharp too much, perhaps too blunt can not go, very inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the not enough of prior art, provide a tip infusion port, this infusion port can use and open through central vein and place the infusion port.

The utility model discloses a concrete technical scheme as follows:

the utility model provides a tip transfusion harbor, including injection seat 1 and pipe 2, the front end of injection seat is connected with the pipe, the structure of the head end of pipe is most advanced 3.

Preferably, the tip 3 is an inclined tip with an inclination angle of 40 to 50 ° forming an inclined plane of 40 to 50 °.

Preferably, the inclination angle is 45 °, forming a 45 ° inclined plane.

Compared with the prior art, the utility model beneficial effect be:

the original structure of the base and the conduit of the transfusion port is not changed; the flat head 3 end of the head end of the transfusion port is changed into the tip 4 with a certain specification, so that secondary catheter cutting treatment is not needed if needed, and particularly, the central vein can be directly inserted into a central vein without secondary cutting when the transfusion port is implanted through central phlebotomy.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

The tip transfusion port comprises an injection seat 1 and a catheter 2, wherein the front end of the injection seat is connected with the catheter 2, and the head end of the catheter is in a tip 4 structure. As shown in figure 2 of the drawings, in which,

further as a preferred embodiment, the tip is a beveled tip with a bevel angle of 40 ° to 50 ° forming a beveled surface of 40 ° to 50 °.

Further as a preferred embodiment, the tip is a slanted tip, the slanted angle is 45 °, forming a 45 ° slanted face.

In clinic, when the infusion port is implanted, a central venous vessel is cut for implantation, and the caliber of the vessel is smaller during cutting, so a pointed infusion port is needed.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will understand that modifications and equivalent substitutions can be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all of them shall fall within the scope of the claims of the present invention.

Claims

1. A tip transfusion port comprises an injection seat and a catheter, wherein the catheter is connected to the front end of the injection seat, and the tip transfusion port is characterized in that the head end of the catheter is in a tip structure, the tip is an inclined tip, and the inclination angle is 40-50 degrees.

2. The port of claim 1 wherein the angle of inclination is 45 ° forming a 45 ° incline.
