Abstract

The utility model relates to a multifunctional thin tube frozen semen delivery gun for a cow, which is formed by an improved design on the basis of the semen delivery gun. The utility model is composed of an antifouling sleeve pipe, a tube of a semen delivery gun body, and a sleeve pipe with plastic films. The tube of the semen delivery gun body is composed of a central tube, a lining tube, and a push rod. The gun can be used for delivering thin tube frozen semen with three models. During semen delivery, a method of holding a rectum can be used for completing the process of the semen delivery. A reproductive organ of an ox can not be damage. After semen delivery, the semen can not flow towards the side, leak toward the side, or maintains on body. The tube of the semen delivery gun body does not be contaminated and is convenient for sterilization. Compared with the long extension type semen delivery (foreign countries), the cost is low.

Description

Multi-functional cattle straw frozen semen spermatic gun

This utility model relates to and a kind ofly carries out test-tube breeding apparatus to cow in estrus, specifically a kind of multi-functional cattle straw frozen semen spermatic gun, it can improve the accurate tire rate of cow, particularly the semen deposition of virgin cattle is used more suitable.

At present, known cattle straw frozen semen spermatic gun is to be made of overcoat, push rod, metal tube etc.With rectum hold is inserted cow vagina deep with seme-deposition device, (two wrinkle wall places) semen deposition in the cervix uteri deep.But, give a lot of cow semen depositions after conception rate on the low side, the other ease of seminal fluid, side leakage or residual phenomena are many during semen deposition, easy damaged cow genitals or be strayed into urethra may cause infection, especially the virgin cattle.

The purpose of this utility model provides a kind of multi-functional cattle straw frozen semen spermatic gun, it can not only be convenient to semen deposition, and can be convenient to tight sterilization, effectively prevent the other ease of seminal fluid side leakage, residual and avoid the genitals damage or infect, cost is lower simultaneously, can be used for three kinds of catheter inseminations.

The purpose of this utility model is achieved in that in the antifouling sleeve pipe of this spermatic gun, spermatic gun main body pipe is connected with the plastic film sleeve pipe.Antifouling sleeve pipe front end is slick sphere, and the top has aperture, connects a small cap in antifouling cannula tip with fine rule.Spermatic gun main body pipe is made up of central canal, bushing pipe and push rod three parts; Bushing pipe is fixed in the central canal, and the outer front end of bushing pipe has screw thread, is used for fixing the plastic film sleeve pipe; Be penetrated with push rod in the central canal, putting back-end pushes away handle.Screw thread on plastic film sleeve pipe and the bushing pipe coincide.Before the artificial insemination, spermatic gun main body pipe and the effective clear water wash clean of dirt proof sleeve, with 75% alcohol rub antifouling telescopic inside and outside, treat that volatilization is done after, seal antifouling cannula tip aperture with medicated cap; Proficiency is directly cervix uteri during semen deposition, another handgrip spermatic gun main body pipe and antifouling sleeve pipe are together held, insert cow vagina deep, clamp main body pipe afterbody with forefinger and middle finger then, little finger of toe fastens antifouling sleeve pipe draw ring, make the main body pipe pass antifouling sleeve pipe, then two handss cooperate, and make spermatic gun enter the insemination site, and thumb pushes away handle, seminal fluid is discharged, finish the first service process; Keep the semen deposition state after the semen deposition, only need its appearance cleaned and dry, after 75% alcohol disinfecting appearance, spermatic gun main body pipe is withdrawed from from antifouling sleeve pipe, on antifouling telescopic cap, shed plastic film sleeve pipe and tubule, can carry out installing and using next time.

Owing to adopting such scheme, can reach a rifle three usefulness, accurately semen deposition, the convenient use and tight sterilization prevents seminal fluid loss and genitals damage or infection; Bushing pipe and plastic film sleeve pipe are only adopted in the spermatic gun top, and be simple in structure.

Below in conjunction with accompanying drawing this utility model is further specified.

Accompanying drawing is the semen deposition state vertical section structural map of spermatic gun embodiment.Among the figure 1, push away handle 2, push rod 3, spermatic gun main body pipe 4, antifouling sleeve pipe 5, screw thread

6, bushing pipe 7, plastic film sleeve pipe 8, seminal fluid 9, piston 10, draw ring

11, freeze fine tube 12, screw thread 13, medicated cap 14, fine rule 15, central canal

Among the embodiment shown in the figure, there is a bushing pipe (6) to be fixed on the central canal (15) in spermatic gun main body pipe (3) front tube by screw thread (5); Be equipped with in the bushing pipe (6) and frozen fine tube (11) after thawing, frozen the same push rod in fine tube (11) rear end (2) top and link to each other, front end links to each other with plastic film sleeve pipe (7) front end; Plastic film sleeve pipe (7) is enclosed within outside the bushing pipe (6), is fixed on the bushing pipe (6) by screw thread (12); Push rod (2) in main body pipe (3) can before and after slide, the thin back segment of its leading portion is thick, the rear end pushes away handle (1) so that semen deposition when advancing firmly; Spermatic gun main body pipe (3) is outer to be equipped with antifouling sleeve pipe (4), and draw ring (10) is equipped with in its rear end, and the front end aperture has small cap (13) sealing.

Antifouling sleeve pipe (4) front end is slick sphere among the figure, plastic film sleeve pipe (7) is made by nontoxic plastic film, its front end is garden taper (top has bore to be convenient to the seminal fluid discharge less than the aperture that freezes fine tube (11) external diameter), damage Niu Yindao in the time of can preventing semen deposition, and can give the semen deposition of virgin cattle easily.Utilize bushing pipe (6) can accomplish a rifle three usefulness (can be used for 0.25ml, 0.5ml Fa Shi tubule and MINITU catheter insemination).Before semen deposition, spermatic gun main body pipe (3), plastic film sleeve pipe (7) and freeze fine tube (11) all in antifouling sleeve pipe (4) can prevent antibacterial and fecal pollution.These advantages can effectively improve the accurate tire rate of cow.
