Lateral holding fowl-used quantified sperm conveying device

Abstract

A lateral holding fowl-used quantified sperm conveying device comprises a piston sleeve with a spermaduct on the front end, and the inner hole of the spermaduct communicates with a piston chamber. An axial elongated hole is arranged in the rear cylinder wall of a piston sleeve and equipped with a sleeve opening plugging end cap. A piston core rod is assembled on the piston sleeve, the piston at the front end of the piston core rod cooperates with the piston chamber, and the rear end of the piston core rod extends to the outside of the piston sleeve after passing through the axial elongated hole and is provided with a core rod translation limiting groove and a convex-head-shaped push button cooperating with the axial elongated hole. A suck-in liquid quantifying and adjusting apparatus formed by a baffle plate, a threaded rod connected to the back of the baffle plate and a rotary handle placed on the rear end of the threaded rod is arranged on the rear portion of the piston sleeve. Suck-in liquid quantifying and adjusting reference scale is arranged on the cylinder wall of the piston sleeve, and the front side of the spermaduct is connected with an externally connected spermaduct through an external rubber sleeve. The lateral holding fowl-used quantified sperm conveying device is simple in structure, flexible for use, and excellent in operation performance and facilitates cleaning, disinfection and accurately control of semen deposition quantity.

Description

technical field [0001] The invention relates to an instrument for artificial insemination, in particular to a horizontal-handled quantitative insemination device for poultry. Background technique [0002] Artificial insemination of poultry is a process in which the male poultry's semen is collected manually, and after direct or appropriate dilution, the semen is injected into the oviduct of the female poultry through the cloaca with an insemination device to fertilize the eggs of the female poultry. Because this technology can improve the fertilization rate of breeding flocks and reduce the number of cocks, it is widely used. At present, the equipment used for artificial insemination of poultry can be roughly divided into three categories. One is the traditional dropper insemination device, which is composed of a straw and a capsule head arranged at the back end of the straw.

Problems solved by technology

At present, the equipment used for artificial insemination of poultry can be roughly divided into three categories. One is the traditional dropper insemination device, which is composed of a straw and a capsule head arranged at the back end of the straw. The suction of semen is completed by squeezing the capsule head of the straw. And injection, simple structure, easy to operate, but the amount of insemination can not be accurately quantified, but the amount of insemination can be mastered by experience; the second type is the insemination device in the form of a medical syringe, which is composed of a syringe with a needle tube at the front end and a matching piston core rod , this type of insemination device requires the cooperation of both hands to complete the semen suction operation. Although the insemination operation can be completed with one hand, it relies on the index finger and middle finger to hold the rear of the syringe, and uses the thumb to push the rear end of the piston core rod. Completing the insemination operation is laborious, and it is difficult to control the stability of the insemination device. Although there is a dose scale on the syringe, it is difficult to accurately control the dose during actual operation; The grip body in the form of a grip and trigger is assembled with a piston injection tube. Although its operability has been improved compared with the insemination device in the form of a medical syringe, its structure is complicated, its durability is poor, and it is inconvenient to clean and sterilize the insemination device.
