2. Description of the Related Art Conventionally, artificial insemination is performed by transferring the collected semen to a test tube and precipitating and concentrating good sperm at the bottom of the test tube by the Percoll method, etc. Is removed and the semen with a high concentration of good sperm remaining at the bottom of the test tube is sucked into a syringe equipped with a fertilization needle made of a metal tube,
This is done by gradually inserting this insemination needle into the uterine ostium through the vagina and then slowly injecting semen into the uterine cavity. By the way, as a conventional insemination needle, there is an insemination needle in which the tip is a closed end and a side hole is provided at a portion facing the cross-sectional diameter of the tip. According to this insemination needle, the tip is not open, so in the process of inserting the insemination needle toward the uterine ostium, vaginal foreign matter such as vaginal secretions may enter the insemination needle or adhere to the side hole. Thus, the injection route of the insemination needle is not blocked.

However, in the conventional fertilization needle, when the small volume of semen existing at the bottom of the tilted test tube is to be sucked into the syringe, the fertilization needle is used. The side holes located in the upper half area of the cross section are communicated with the atmosphere in the test tube without being submerged in the semen, and the syringe does not empty the atmosphere to suck a necessary amount of semen. In this case, precious good sperm concentrated by the Percoll method or the like cannot be effectively used, and the expected improvement in pregnancy rate cannot be obtained. The present invention, the semen injection route is not blocked by foreign substances in the vagina at the time of insertion toward the uterine ostium, and the semen with a high sperm concentration present at the bottom of the test tube can be reliably aspirated, and the uterus at the time of use It is an object of the present invention to provide a catheter for artificial insemination that causes less damage to the intima.

The injection catheter 20 is substantially different from the injection catheter 10 to be described later in that the hub attached to the proximal end portion of the catheter tube 22 and the curved flange portion 24 capable of closely contacting the uterine ostium 17 with the hub. Is provided. Therefore, this catheter tube 22 is also similar to the catheter tube 12 shown in FIG.
Made of flexible material such as vinyl chloride resin
It is bendable and has a spherical rounded outer surface. In addition, since the catheter tube is made of a flexible material, it can be smoothly inserted into any uterine shape without being bent and damaging the endometrium. Moreover, the rounded outer surface of the distal end of the catheter tube also prevents damage to the endometrium during insertion. When bleeding is caused by damage to the endometrium,
The pregnancy rate decreases. Further, the flange portion 24 may have a step shape or a flat plate shape instead of the curved surface shape. This flange 2
According to 4, it is possible to prevent outflow of semen injected into the uterine cavity 18.

According to the injection catheter 10, since the tip of the catheter tube 12 is not open, foreign substances in the vagina enter the inside of the catheter tube 12 in the process of inserting the catheter tube 12 toward the uterine ostium 17. It does not adhere to the side hole 13 and the semen injection path of the catheter tube 12 is not blocked.
Further, when a small volume of semen existing at the bottom of the test tube 15 set in the inclined state is to be sucked into the injection tube 11, the side hole 13 in one half area of the cross section of the catheter tube 12 is directed downward. By facing the bottom of the test tube 15,
There is no possibility that the side hole 13 of the catheter tube 12 is exposed to the outside of the semen and the atmosphere is evacuated until the whole semen is completely sucked, and semen with a high sperm concentration can be surely sucked.
