Plug of artificial insemination tube for livestock breeding

Abstract

A plug of an artificial insemination tube for livestock breeding includes a leading portion and a viewing portion, each having different color layers or different hardness layers, and being formed by stacking and combining different foam layers. In an artificial insemination for livestock breeding, the plug installed at the front of a sperm delivery duct is inserted into a reproductive organ of the livestock, and secretion or fluid is attached and shown on surfaces of the plug leading portion and the viewing portion with different colors to achieve the effect of detecting the physical and physiological conditions of the livestock. In addition, the leading portion is a foam layer with relatively greater hardness, density, and smoothness, so that the plug may be entered into the female livestock body more easily, and the injection hole will not be deformed easily, so as to improve the smoothness and efficiency of the artificial insemination.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) With reference to FIGS. 3 and 4 for a plug of an artificial insemination tube for livestock breeding in accordance with this disclosure, the plug 20 is installed at the front of a sperm delivery duct 10 of an artificial insemination tube, and the plug 20 comprises a leading portion 203 and a viewing portion 204, wherein the leading portion 203 and the viewing portion 204 are integrally formed by stacking foam layers formed by foaming a foam material (such as ethylene vinyl acetate (EVA)), and the leading portion 203 and viewing portion 204 formed by stacking the foam layers have different hardness layers or color layers. Wherein, each of the leading portion 203 and the viewing portion 204 of the plug 20 has one or more foam layers.

(7) After the leading portion 203 and the viewing portion 204 of the plug 20 are stacked and combined with each other, an injection hole 202 is formed at the leading portion 203, and a sleeve aperture 201 is formed between the leading portion 203 and the viewing portion 204 and communicated with the injection hole 202, and the sleeve aperture 201 is provided for installing the sperm delivery duct 10.

(8) Wherein, the leading portion 203 of the plug 20 is formed by foaming a foam material, which is a hard layer with a relatively better hardness, and the peripheral surface of the hard layer has better density and smoothness.

(9) Wherein, the viewing portion 204 of the plug 20 is formed by foaming a foam material, which is a soft layer softer than the leading portion 203.

(10) Wherein, the leading portion 203 and the viewing portion 204 of the plug 20 are formed by different color layers, and made of stacking the foam materials of different colors, or coating different color films onto the peripheral surface of the plug 20 after the foaming and forming processes.

(11) Wherein, the leading portion 203 and the viewing portion 204 of the plug 20 are formed by stacking and combining single-layer foams into a plug 20. With reference to FIG. 5, the leading portion 203 of the plug 20 may be formed by foaming and stacking a plurality of layers of foams 2031, 2032, and the viewing portion 204 of the plug 20 may be formed by foaming and stacking a plurality of layers of foams 2041, 2042, 2043. Each layer of foams 2031, 2032 in the leading portion 203 and each layer of foams 2041, 2042, 2043 in the viewing portion 204 may be a different color layer, and each layer of foams 2041, 2042, 2043 in the viewing portion 204 may be a different hardness layer. In addition, after the leading portion 203 and the viewing portion 204 are foamed and stacked to form the plug 20, the leading portion 203 is a hard layer.

(12) In an artificial insemination of a livestock, the plug 20 installed at the front of the sperm delivery duct 10 is inserted into the livestock vagina slowly, and the leading portion 203 of the plug 20 is a hard layer, so that the leading portion 203 of the plug 20 pushed and entered into the female livestock body will not be deformed easily, so that the injection hole 202 formed at the leading portion 203 will not be deformed, decreased, narrowed, or blocked. After the plug 20 enters into the uterus of the livestock and a user injects semen of the livestock stored in a semen bottle or bag (not shown in the figure) which is installed at the rear of the sperm delivery duct 10 into the sperm delivery duct 10, the livestock semen contained in the sperm delivery duct 10 can enter smoothly and quickly into the female livestock body through the injection hole 202 of the plug 20 to achieve the effect of improving the smoothness and efficiency of the artificial insemination. Of course, the leading portion 203 of the plug 20 is a hard layer with greater density and smoothness, so that the plug 20 can be entered into the female livestock body more easily and smoothly during the artificial insemination procedure, and the female livestock body will not produce repellence.

(13) In the artificial insemination for livestock breeding, the plug 20 of an artificial insemination tube is inserted slowly along the livestock vagina into the uterus, and then removed after the artificial insemination procedure ends. Since the secretion or other fluid of the female livestock body will be attached onto the peripheral surface of the plug 20 automatically and the leading portion 203 and the viewing portion 204 of the plug 20 have different color layers, and the predetermined different color layers are provided for showing the color of the secretion or fluid, therefore a technician carrying out the artificial insemination is naturally capable of detecting the physical and physiological conditions of the livestock clearly and conveniently to achieve the effects of preventing illness and controlling the first opportunity of curing. If the livestock is injured accidentally while the artificial insemination tube is being extended into the female livestock body, blood stains may be attached onto the peripheral surface of the light colored leading portion 203 or viewing portion 204 of the plug 20, so that we can know the situation clearly and take care of the situation immediately to achieve the early treatment effect. In addition, the secretion of a healthy female livestock body is generally transparent, and any colored secretion attached onto the peripheral surface of the dark colored leading portion 203 or viewing portion 204 of the plug 20 indicates a poor physical or physical condition of the female livestock body, so that we can know the situation clearly and handle the situation immediately.

(14) In other words, the plug of an artificial insemination tube for livestock breeding of this disclosure has the following advantages:

(15) 1. Simple installation and high cost effectiveness.

(16) 2. Simple, easy, convenient, and quick operation and use.

(17) 3. Highly smooth and efficient artificial insemination for livestock breeding.

(18) 4. Applicable for the artificial insemination and the detection of physical and physiological conditions of a female livestock body to provide diversified functions.
