Convenience, good operation quality and high safety.

Description

A sheep embryo transplanter used in conjunction with a thin tube

technical field

The invention belongs to animal embryo bioengineering equipment, and mainly relates to a simple and simple embryo transplantation equipment for sheep used in cooperation with embryo thin tubes.

Background technique

There are two traditional sheep embryo transfer methods: one method is to release the embryos stored in the embryo tube into the petri dish, and then put it into the transfer needle under the microscope, and then transfer it to the oviduct or uterine horn of the ewe. However, this method faces the risk of embryo loss and bacterial contamination; the second method is to cut the embryo thin tube, and then directly insert it into the oviduct of ewe for embryo transfer, but because the diameter of the thin tube is relatively small compared to the lumen of the oviduct Large, this method is difficult to operate, it is easy to cause damage to the oviduct of ewes, and it is impossible to transfer embryos to the uterine horn. At present, there is a need for a simple and practical embryo transfer device that can be used in conjunction with embryonic tubes, which can directly perform oviduct embryo transfer and uterine horn embryo transfer, so as to realize fast and accurate transfer of sheep embryos to designated positions .

Contents of the invention

The purpose of the present invention is to solve the problems existing in the above-mentioned traditional sheep embryo transfer technology, combined with the actual needs of the sheep embryo transfer operation, to design and provide a sheep embryo transfer device used in conjunction with thin tubes, so as to avoid the loss of embryos during the sheep embryo transfer process and bacterial contamination, reduce damage to sheep, easy operation and use, fast transplantation, good transplant quality and high efficiency.

The basic design created by the present invention is that a sheep embryo transfer device used in conjunction with thin tubes includes embryo thin tubes, and the lower end and upper end of the input tube seat are equipped with conical embryo input tubes and fasteners respectively. The lower part of the tube is inserted into the input tube seat, the lower end of the embryo thin tube contacts and seals with the conical inner wall of the conical embryo input tube, and the embryo thin tube is axially clamped and locked on the input tube seat by the fastener, The lower part of the syringe is sealed with a flexible hose, and the upper part of the embryo thin tube is sealed and fitted in the flexible hose.

The beneficial effects created by the invention are: it can be effectively used in cooperation with the embryonic tube, and has the characteristics of reasonable design, simple structure, convenient use, good operation quality and high efficiency, and solves the problem of direct transplantation of embryos stored in the embryonic tube, effectively Improved embryo survival.

Description of part number in the figure:

1. Syringe, 2. Flexible hose, 3. Fastener, 4. Embryo thin tube, 5. Input tube seat, 6. Tapered embryo input tube.

Detailed ways

The best embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. A sheep embryo transfer device used in conjunction with thin tubes includes embryo thin tubes 4, conical embryo input tubes 6 and fasteners 3 are respectively equipped on the lower end and upper end of the input tube seat 5, and the lower part of the embryo thin tubes 4 Inserted in the input pipe seat 5, the lower end of the embryo thin tube 4 contacts and seals with the conical inner wall of the conical embryo input pipe 6, and the embryo thin tube 4 is axially clamped on the input pipe seat 5 by the fastener 3 Tightly locked, the flexible hose 2 is sealed on the lower part of the syringe 1, and the upper part of the embryo thin tube 4 is sealed and fitted in the flexible hose 2. The embryo thin tube 4, the input tube seat 5 and the tapered embryo input tube 6 are all made of transparent materials.

During the operation, first pull the piston of the syringe 1 to the top position, cut off the sealing and blocking part of the lower end of the embryonic tubule 4, place the lower side of the embryonic tubule 4 in the input tube seat 5, and use the fastener 3 Lock the position, then cut off the sealed and blocked part of the upper end of the thin embryo tube 4, and insert the upper side of the thin embryo tube 4 into the flexible hose 2. When in use, the conical embryo input tube 6 is inserted into the oviduct or uterine horn of the ewe, the piston of the syringe 1 is pushed, and the embryo in the embryo thin tube 4 is transported to the sheep oviduct or oviduct through the compressed air through the conical embryo input tube 6. In the uterine horn, complete the transplant operation. The sealing cooperation between the lower end of the embryo thin tube 4 and the tapered inner wall of the conical embryo input tube 6 can effectively prevent the embryo preservation solution from flowing back during the transplantation process. The thin embryo tube 4, the input tube seat 5 and the tapered embryo input tube 6 are made of transparent materials, which realize the visibility of the flow of the embryo preservation solution.
