Abstract

An artificial insemination catheter belongs to a medical device. It includes an outer catheter, an inner catheter and a needle seat. The inner catheter includes a front end, a nozzle hole and an inner catheter body. The front end of the inner catheter is a semicircular closed structure, and the nozzle hole is adjacent to the front end of the inner catheter. The main body of the inner catheter is inserted into the outer catheter, and the length is longer than that of the outer catheter. The end of the inner catheter is connected to a needle hub, and the needle hub has a Luer interface. The utility model adopts the above-mentioned structure, which can smoothly push the front end of the inner catheter deep into the uterus, prevent buckling of the catheter after entering the vagina, and prevent intrauterine secretions from entering the catheter during insertion.

Description

artificial insemination catheter

technical field

The utility model belongs to the field of medical equipment, in particular to an artificial insemination catheter.

Background technique

At present, many infertile couples have successfully obtained pregnancy through artificial insemination technology, which is a simple and economical non-surgical treatment. In the process of artificial insemination, due to the limitations of its own structure and different uterine shapes, the existing fertilization tube often cannot reach the deep part of the uterine horn, and cannot effectively improve the pregnancy rate.

Contents of the invention

In order to solve the above existing problems, the utility model provides an artificial insemination catheter, which can send sperm into the deep part of the uterine horn according to the specific uterine shape, and has a simple structure and easy operation.

The purpose of this utility model is achieved by the following scheme: an artificial insemination catheter includes an outer catheter, an inner catheter and a needle seat, the inner catheter includes a front end, a nozzle hole and an inner catheter body, and the front end of the inner catheter is a semicircle Shaped closed structure, the same diameter as the outer conduit or slightly larger than the diameter of the outer conduit, the nozzle hole is close to the front end of the inner conduit, the nozzle hole includes two, the position corresponds to the front and back, the main body of the inner conduit is inserted into the outer conduit The inner catheter is longer than the outer catheter, and the end of the inner catheter is connected to a needle hub, and the needle hub has a Luer interface.

The surface of the outer catheter is engraved with a distance scale.

Beneficial effects of the utility model: the utility model adopts the above-mentioned structure, can smoothly enter the female vagina, can smoothly push the front end of the inner catheter to the depth of the uterus, prevent the vagina or uterus from being scratched during use, and prevent buckling of the catheter after entering the vagina , while preventing uterine secretions from entering the catheter during insertion.

In the figure, 1-inner catheter, 2-outer catheter, 3-needle seat, 4-nozzle hole, 5-front end, 6-syringe.

Detailed ways

Among Fig. 1, this artificial insemination catheter comprises inner catheter 1, outer catheter 2, needle base 3, and the material of described outer catheter 2 is medical rigid material, and the surface of described outer catheter 2 is engraved with distance scale, and described inner catheter 1 The material of the inner catheter 1 is polyethylene, the main body of the inner catheter 1 is inserted into the outer catheter 2, the needle hub 3 is located at the end of the inner catheter 1, and the needle hub 3 has a Luer interface to provide connection for standard syringes interface.

In Fig. 2, the inner conduit 1 includes a front end 5, a nozzle hole 4 and an inner conduit main body (not shown), the front end 5 is a closed semicircular structure, and the diameter of the front end 5 is the same as or slightly smaller than that of the outer conduit 2. It is larger than the diameter of the outer conduit 2, and the nozzle hole 4 is adjacent to the front end 5. The nozzle hole 4 includes two, and the positions correspond to each other. The syringe 6 is a standard syringe.

When in use, in the state of pulling the inner catheter 1 into the outer catheter 2 (Figure 1), insert the catheter from the vaginal opening into the uterus, judge the depth of the catheter entry according to the distance scale on the surface of the outer catheter, and then push slowly Inner catheter 1, push the front end 5 of the inner catheter 1 out from the front end of the catheter, make the nozzle hole 4 reach the depth of the uterus, slowly push the fertilized egg or sperm in the syringe 6 into the inner catheter 1, and supply the fertilized egg through the nozzle hole 4 Or sperm, then pull the inner catheter 1 into the outer catheter 2, and pull the catheter out of the vagina.

Claims (2)
