AI Technical Summary

Technical Problem

Existing non-surgical embryo transfer methods for pigs have problems such as difficulty in getting the embryo to the appropriate fertilization site, uncontrollable insertion depth, easy bending, and embryo backflow. In addition, the existing equipment is complex and costly, making it unsuitable for large-scale promotion.

Method used

A combined non-surgical ultra-deep embryo transfer vas deferens was designed, including a regular vas deferens, an ultra-deep vas deferens, and an ultra-deep embryo transfer tube. Guided by ultrasound images, a white strong echo image is formed in the body through a metal connector, and it is precisely inserted into the uterine horn. Combined with scale lines and a flexible design, bending is avoided, ensuring that the embryo reaches the designated position.

Benefits of technology

It improves the pregnancy and delivery efficiency of non-surgical embryo transfer, reduces the risk of embryo reflux, and lowers the complexity and cost of equipment, making it suitable for large-scale promotion.

Abstract

The utility model relates to a kind of combined non-surgical method super-deep embryo transfer insemination tube for pig, and the transfer tube includes: ordinary insemination tube, super-deep insemination tube and super-deep embryo transfer tube, which is used for the transport of embryo or semen after combination. The ordinary insemination tube is used for inserting into vagina dilatation cervix, so that the super-deep insemination tube can pass through vagina and cervix. The super-deep insemination tube has a metal connector and a silicone soft tip at its front end. The super-deep embryo transfer tube has a standard luer taper syringe interface at its tail end. Compared with the prior art, the utility model is specially developed according to the existing problems of non-surgical embryo transfer, and is innovative on the basis of retaining the advantages of non-surgical embryo transfer. Under the visual field, the catheter can be accurately inserted into the specified position, which can prevent embryo reflux and effectively solve the problems of blind insertion method, such as uncontrollable insertion depth, bending of embryo transfer tube and embryo reflux, thereby improving the efficiency of non-surgical embryo transfer pregnancy delivery.

Claims

1. A combined non-surgical super-deep embryo transfer insemination tube for pigs, comprising a common insemination tube (1), a super-deep insemination tube (2) and a super-deep embryo transfer tube (3) combined for embryo or semen delivery, characterized in that: Ordinary vas deferens (1) is used to insert into the vagina to dilate the cervix. Assisted ultra-deep vas deferens (2) passes through the vagina and cervix. Assisted ultra-deep vas deferens (2) can be inserted into the target position of the uterine horn under the guidance of external ultrasound. Assisted ultra-deep embryo transfer tube (3) enters the uterine horn or transports fresh semen, frozen semen, or sex-controlled semen of high-value breeding pigs.

2. The combined non-surgical super deep embryo transfer insemination tube for pigs according to claim 1, characterized in that, The front end of the ultra-deep vas deferens (2) is provided with a silicone soft head (23). The silicone soft head (23) of the ultra-deep vas deferens (2) and the main tube are provided with a hollow metal connection structure (22), which can form a white strong echo image under the action of external B-ultrasound to guide the operator to insert the tube into the target position.

3. The combined non-surgical super deep embryo transfer insemination tube for pigs according to claim 2, characterized in that, The ultra-deep vas deferens (2) is provided with a scale segment (21) with centimeter graduations.
