The arrangement of the double-cavity channel and the inner support wire enhances the controllability of the catheter, so that the front end of the catheter can be pre-bent into a required shape or angle according to the actual situation, the cervical vertebra can be easily passed through, the operation is simple, and a catheter support part is not required to be additionally used; the inner tube of the catheter at the far end of the catheter is soft, so that the damage to the cervix and the endometrium is minimized; the outer tube of the catheter positioned at the near end of the catheter is made of rigid material, so that the controllability is better; the front end of the catheter is round and smooth, can smoothly pass through the cervix and prevent from damaging endometrium; the holes on both sides of the end of the catheter make it easier for the semen to disperse inside the uterus.
Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a double-channel artificial insemination transplanting tube.
Background
Artificial insemination is an assisted reproduction technique, and generally adopts a transplantation tube to push semen into the uterus through the vagina so as to achieve the goal of conception. The catheter of the prior artificial insemination transplanting tube is usually made of a single material, and the hardness of the catheter at different positions is consistent, so that the catheter cannot be suitable for physiological bending of visceral organs, and is not convenient for being matched with an operator to operate. For example, CN208756115U discloses an artificial insemination graft tube, the tube body of which is uniform in hardness. In addition, the existing catheters of the artificial insemination transplanting tube usually adopt a mode of top end opening, and semen only enters the uterus through the top end opening, so that the semen is not favorably dispersed in the uterus.

Preferably, the inner support wire is made of stainless steel for supporting the catheter inner tube so as to be pre-bent into a desired form or angle.
Preferably, the side openings are two to facilitate dispersion of semen within the uterus.
Preferably, the inner catheter tube is made of a flexible material, so that damage to the cervix and endometrium can be minimized, and the outer catheter tube is made of a rigid material, so that the controllability is good, and the operation of an operator is facilitated.
The invention has the beneficial effects that:
the invention has the advantages that the arrangement of the double-cavity channel and the inner support wire enhances the controllability of the catheter, so that the front end of the catheter can be pre-bent into a required shape or angle according to the actual situation, the cervical vertebra can be more easily passed through, the operation is simple, and a catheter support part is not required to be additionally used; the inner tube of the catheter at the far end of the catheter is soft, so that the damage to the cervix and the endometrium is minimized; the outer tube of the catheter positioned at the near end of the catheter is made of rigid material, so that the controllability is better; the front end of the catheter is round and smooth, can smoothly pass through the cervix and prevent from damaging endometrium; the holes on both sides of the end of the catheter make it easier for the semen to disperse inside the uterus.
Drawings
FIG. 1 is a schematic illustration of a dual lumen artificial insemination graft of an embodiment of the present invention;
fig. 2 is a schematic cross-sectional view of a double lumen artificial insemination graft of an embodiment of the invention.
Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that the examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that various changes or modifications can be made by those skilled in the art after reading the disclosure of the present invention, and such equivalents also fall within the scope of the invention.
As shown in fig. 1, the double lumen artificial insemination graft of the present embodiment includes a catheter hub 1, a catheter and an inner support wire 5. The catheter consists of a catheter outer tube 2 and a catheter inner tube 3, the catheter inner tube 3 is sleeved in the catheter outer tube 2, the outer surface of the catheter inner tube 3 is tightly attached to the inner surface of the catheter outer tube 2, the length of the catheter inner tube 3 is larger than that of the catheter outer tube, and the extended part of the catheter inner tube forms the distal part of the catheter.
One end of the outer catheter tube 2 is connected with the catheter holder 1, and the other end of the outer catheter tube 2 is provided with a distance indicating mark 6 for indicating the depth of the catheter entering the uterus. Two side openings 4 are arranged at the position of the inner tube 3 of the catheter close to the end part, so that the semen can be conveniently dispersed in the uterus. The front end of the catheter inner tube 3 is round and smooth, and the damage to the endometrium is reduced. As shown in fig. 2, the catheter inner tube 3 is a double-lumen tube, both tubes run through the catheter inner tube 3, one tube has a smaller space for accommodating the inner support wire 5, and the other tube has a larger space for semen transplantation.
The inner support wire 5 can be made of stainless steel or other materials with proper rigidity, so that the condition that the inner support wire is easy to bend and can keep a fixed shape when entering a human body is met.
