Abstract
Description
Technical Field
[0001] This utility model relates to tools for artificial insemination of sheep, specifically a novel insemination device. Background Technology
[0002] For sheep reproduction, artificial insemination is the most efficient and highest quality method. It has many advantages, such as high conception rate, no geographical or time restrictions, accelerated breeding speed, and prevention of disease transmission.
[0003] The main steps of artificial insemination in sheep are semen collection and insemination. Semen collection is currently performed using specialized semen collection devices to collect semen from rams. Insemination devices come in various structures, the most common being a simple needle-shaped insemination gun. This gun, combined with a syringe, draws the semen and inserts it into the ewe's cervix or uterus for insemination. However, this type of insemination device has certain drawbacks. Specifically, after drawing the semen with the insemination gun, it is easy for the semen to leak out during insemination, resulting in semen loss. Furthermore, it is not easy to disinfect the semen, leading to cross-contamination. Summary of the Invention
[0004] This invention relates to a novel insemination device, which is equipped with a separate reservoir tube for storing semen. In use, the semen is drawn into the reservoir tube, and during insemination, the reservoir tube is inserted into the insemination device to perform the insemination operation, thus avoiding the loss of semen. At the same time, the semen in the reservoir tube can also avoid contamination.
[0005] The present invention achieves the above objectives using the following technical solutions:
[0006] A novel insemination device includes a semen storage tube, a semen extraction assembly, and an insemination assembly. The semen storage tube has a tubular structure with silicone diaphragms near the ends on both sides. The silicone diaphragms are multi-fan-shaped structures, forming a complete circular structure. The semen extraction assembly includes a semen extraction connector and a conversion connector. The semen extraction connector is installed at the front of the semen storage tube for introducing semen into the tube, and the conversion connector is installed at the rear of the semen storage tube for docking with a syringe. The insemination assembly includes a catheter and an insemination head, which are connected to each other. The tail end of the catheter docks with the syringe. During insemination, the semen storage tube is installed inside the insemination head.
[0007] The ejaculation connector has a cylindrical structure. The ejaculation connector has an ejaculation tube at the front. The ejaculation tube extends a certain distance into the ejaculation connector. When the ejaculation connector is installed at the front of the sperm storage tube, the tail of the ejaculation tube passes through the silicone diaphragm at the front of the sperm storage tube and extends into the sperm storage tube.
[0008] The adapter consists of two interconnected stepped tubes; the front section is used to install the sperm storage tube, and the rear section is used to connect to the syringe.
[0009] The insemination head is a tubular structure with a tapered protrusion at the front and a through hole at the center of the protrusion. Inside the insemination head is a stepped section that supports the sperm storage tube. The inner side of the tail of the insemination head has an internal thread, and the front of the catheter has an external thread corresponding to the internal thread at the tail of the insemination head. The catheter and the insemination head are connected to each other to form a smooth cylindrical structure. The tail of the catheter has a connector for connecting to a syringe.
[0010] Furthermore, the stepped portion inside the insemination head is provided with a positioning post that is inserted into the front of the sperm storage tube. The center of the positioning post is provided with an inverted conical bevel, and the bottom of the bevel is connected to the through hole. When the sperm storage tube is installed inside the insemination head, the positioning post is inserted into the front of the sperm storage tube and does not pass through the silicone diaphragm.
[0011] Furthermore, an annular gap is left between the positioning post and the tube wall of the insemination head, and a support spring is provided in the gap. When the insemination tube is installed in the insemination head, its end is squeezed against the support spring, and the tail of the insemination tube is supported by a conduit installed at the tail of the insemination head.
[0012] The present invention, by adopting the above-described technical solution, has the following beneficial effects:
[0013] This device is equipped with a separate semen storage tube, which can prevent semen contamination during insemination. The silicone inside the storage tube is in a closed state when not subjected to external force, effectively protecting the semen inside.
[0014] In practical use, semen can be drawn into the sperm storage tube in advance for storage. During the insemination operation, only the sperm storage tube needs to be replaced, which saves the process of repeated extraction and reduces the risk of semen contamination that may occur during the process.
[0015] The device's corresponding insemination head and catheter, once installed, form a single cylindrical structure, making disinfection and sterilization more convenient. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] like Figures 1-5 The present invention discloses a novel insemination device, comprising a semen storage tube 1, a semen extraction assembly 2, and an insemination assembly 3. The semen storage tube 1 is a tubular structure with silicone diaphragms 101 located near the ends on both sides of the semen storage tube 1. The silicone diaphragms 101 are multi-fan-shaped structures, forming a complete circular structure. The semen extraction assembly 2 includes a semen extraction connector 201 and a conversion connector 202. The semen extraction connector 201 is installed at the front of the semen storage tube 1 for introducing semen into the tube, and the conversion connector 202 is installed at the rear of the semen storage tube 1 for docking with a syringe 0. The insemination assembly 3 includes a catheter 301 and an insemination head 302, which are connected to each other. The tail end of the catheter 301 docks with the syringe 0. During insemination, the semen storage tube 1 is installed inside the insemination head 302.
[0023] The ejaculation connector 201 has a cylindrical structure. The ejaculation connector 201 has an ejaculation tube 203 at the front. The ejaculation tube 203 extends a certain distance into the ejaculation connector 201. When the ejaculation connector 201 is installed at the front of the sperm storage tube 1, the tail of the ejaculation tube 203 passes through the silicone diaphragm 101 at the front of the sperm storage tube 1 and extends into the sperm storage tube 1.
[0024] The adapter 202 consists of two interconnected stepped tubes, with the front part used to install the sperm storage tube 1 and the rear part used to connect with the syringe 0.
[0025] The insemination head 302 is a tubular structure. The front part of the insemination head 302 is provided with a tapered protrusion 303, and a through hole 304 is provided at the center of the protrusion 303. The insemination head 302 is provided with a stepped part 305 to support the sperm storage tube 1. The inner side of the tail of the insemination head 302 is provided with an internal thread. The front part of the conduit 301 is provided with an external thread corresponding to the internal thread of the tail of the insemination head 302. The conduit 301 and the insemination head 302 are connected to each other to form a smooth columnar structure. The tail of the conduit 301 is provided with a connector 306 for connecting with the syringe 0.
[0026] Furthermore, the step portion 305 inside the insemination head 302 is also provided with a positioning post 307 that is inserted into the front of the sperm storage tube 1. The center of the positioning post 307 is provided with an inverted conical bevel 308, and the bottom of the bevel 308 is connected to the through hole 304. When the sperm storage tube 1 is installed in the insemination head 302, the positioning post 307 is inserted into the front of the sperm storage tube 1 and the positioning post 307 does not pass through the silicone diaphragm 101.
[0027] Furthermore, an annular gap is left between the positioning post 307 and the tube wall of the insemination head 302, and a support spring 309 is provided in the gap. When the sperm storage tube 1 is installed in the insemination head 302, its end is squeezed against the support spring 309, and the tail of the sperm storage tube 1 is supported by the conduit 301 installed at the tail of the insemination head 302.
[0028] When using this device, semen can be drawn into the sperm storage tube in a relatively clean environment. The specific operation is as follows: insert the sperm extraction connector into the front of the sperm storage tube, so that the sperm extraction tube inside the sperm extraction connector is inserted into the silicone diaphragm at the front of the sperm storage tube. Then, install the adapter and syringe at the tail of the sperm storage tube. When drawing semen with the syringe, under the negative pressure inside the syringe, the air will drive the silicone diaphragm at the rear of the sperm storage tube to open, drawing the semen into the sperm storage tube through the sperm extraction tube.
[0029] Then remove the adapter and the semen extraction connector. At this time, the silicone diaphragm returns to a horizontal state under its own elasticity, blocking the semen inside and preventing it from leaking out of the sperm storage tube.
[0030] During insemination, the insemination tube is inserted into the insemination head, and then the catheter is installed at the tail of the insemination head. The catheter is installed via threads, and during installation, it supports the tail of the insemination tube, allowing the tip of the insemination tube to be inserted into the positioning post. The catheter and insemination head are then inserted into the ewe's uterus, and injection is performed through the tail of the catheter using a syringe. Under the pressure of the syringe, the silicone diaphragm inside the insemination tube opens, injecting semen into the ewe's uterus through the through-hole in the insemination head. The positioning post inside the insemination head positions the insemination tube, and the bevel at the end of the positioning post facilitates semen delivery. A support spring supports and fixes the insemination tube, and when it is necessary to remove the insemination tube, it can be pushed backward from the insemination head for easy removal.
