Automatic insemination container for pigs with membrane tube structure

Abstract

The invention provides an automatic seminal liquid conveying container provided with a membrane tube and used for pigs. The automatic seminal liquid conveying container comprises a membrane tube, an inner plug, an inner fixing tube and an outer fixing tube; the membrane tube is made through blowing of elastomer plastic, wherein the bottom of the membrane tube is a heat seal and the upper portion is clamped between the inner fixing tube and the outer fixing tube; the inner fixing tube is provided with the inner plug therein; seminal liquid can be injected from a gap between the inner plug and the inner fixing tube; a seminal liquid conveying tube is also inserted from the gap and the membrane tube can be pushed to the rear edge of the head of the seminal liquid conveying tube by pushing the outer fixing tube; when the seminal liquid conveying tube is inserted in to the vagina of a sow, the membrane tube is also inserted; seminal liquid can be pressed into the uterus of the sow by means of the resilience force of the membrane tube and the closing force of the vaginal wall; a recessed groove of the inner plug can form a conveying channel under specific conditions to convey seminal liquid from the membrane tube into the seminal liquid conveying tube-uterus. The automatic seminal liquid conveying container can be used together with most existing seminal liquid conveying tubes and is low in price, so that the automatic seminal liquid conveying container can be accepted by users and markets easily.

Description

technical field [0001] The invention relates to the technical field of assisted reproduction in aquaculture, in particular to an automatic insemination container for pigs with a membrane tube structure. Background technique [0002] At present, boar semen containers on the market can be basically divided into four categories: the first category is the bottle-shaped container semen bottle, which has the longest history of use, simple structure and relatively economical, but generally requires human labor when inseminating sows. Holding the vas deferens and the semen bottle for 5-10 minutes is labor-intensive. This type of semen container is bulky and not conducive to long-distance transportation; the second type is a bag-shaped container semen bag, which is used in a similar way to the semen bottle, but due to the need Filling semen with a special filling machine is not accepted by most users; the third type is the composite insemination device in which the vas deferens and t...

[0002] At present, boar semen containers on the market can be basically divided into four categories: the first category is the bottle-shaped container semen bottle, which has the longest history of use, simple structure and relatively economical, but generally requires human labor when inseminating sows. Holding the vas deferens and the semen bottle for 5-10 minutes is labor-intensive. This type of semen container is bulky and not conducive to long-distance transportation; the second type is a bag-shaped container semen bag, which is used in a similar way to the semen bottle, but due to the need Filling semen with a special filling machine is not accepted by most users; the third type is the composite insemination device in which the vas deferens and the semen container are combined together, that is, the vas deferens is coated with a layer of elastomer tube or An elastomer capsule is connected to the rear end of the insemination device rod. This type of insemination device has a relatively complicated structure and a high price. It also requires a special filling machine to fill the semen, which is not easy to be widely accepted; the fourth category is The automatic insemination container with a closed vial-shaped structure made of elastomer material is complicated to fill semen, and the automatic insemination container hangs at the back end of the vas deferens during insemination, which may drag the vas deferens out without promotion
