Abstract

The invention relates to animal husbandry. The aim of the invention is to increase the effectiveness of insemination by ensuring reliable operation. The device for artificial insemination of animals contains a handle 1, on which a working stem (PC) 2 is fixed. At the attachment point of the PC with the handle 1, a lock chamber (CC) 7 is mounted, the internal cavity of which communicates with the PC channel. A removable magazine 13 is mounted above the barcode. Shop 13 contains a Dewar vessel, in the cavity of which a mesh cup is placed. The mesh cavity is filled with a porous absorbent material. Along the axis of the net glass, a container is rigidly fixed into which the granulated bioproduct is loaded. The magazine 13 is attached to the CC 7. The window 8 of the CC is closed with a shutter-pusher 11. The vapor of the cryogenic liquid is discharged through the exhaust duct 10 of the CC. Then, the pusher gate 11 is retracted to the rearmost position. HQ receives granulated bioproduct. PC devices are inserted into the animal's cervical canal. The pusher gate 11 pushes a portion of the biproduct from HQ to the PC channel, from which the bioproduct is pushed by mandrin 3. 2p. p. f-ly, 2 ill. (L 00 oo 00

Description

one

The invention relates to a device for artificial insemination of farm animals with deep frozen sperm and can be used in animal breeding.

The purpose of the invention is to increase the effectiveness of insemination by ensuring reliable operation.

Figure 1 shows a device for artificial insemination of animals; Fig. 2 shows a device for artificial insemination of animals.

The device for artificial insemination of animals contains a handle 1 on which the working stem 2 is fixed. A mandrel 3 is inserted into the bore of the working stem 2. Mandrin 3 is equipped with an elastic tension element 4 and is connected with kinematic elements 5 with a trigger guard 6 fixed to handles 1.

In the place of attachment of the working shaft 2 to the handle 1, a lock chamber 7 is mounted, the internal cavity of which communicates with the channel of the working shaft 2. In the upper part of the LENS chamber 7 there is a round window 8 for the entry of bioproducts. Inside the lumen chamber 7, on one side of the window 8, a pivot flap 9 is fixed, and on the other side there is a flue channel 10, into which a spring-loaded pusher 11 is pushed.

A removable magazine 13 of an artificial insemination device for animals is mounted above the lock chamber 7. The magazine 13 contains a Dewar vessel 14 installed in such a way that its axis of symmetry passes through the geometric center of the window 8. In the cavity of the Dewar vessel 14, mesh glass 15 is aligned with it. Along the axis of the mesh glass 15, it is rigidly fixed container 17 for granulated sperm. The bottom of the net glass 15 is filled with porous hygroscopic material 18 by silica gel impregnated with a cryogenic liquid (liquid nitrogen). The ribs 16 are made of a waterproof material, such as a perforated metal. The cavity of the container 17 communicates with the cavity of the sluice chamber through the window 8 and is located between the sluice chamber and the container bellows 19.

The device works as follows.

A store 13 is pre-prepared for operation, the impregnation of a porous hygroscopic material of which is carried out by simply pouring liquid nitrogen into the cavity of the Dewar 14 followed by draining the non-absorbed residue. A granulated bioproduct is then loaded into the container 17, after which the magazine 13 is attached to the bladder chamber of the device. The window 8 at this moment is blocked by the push-rod 11, which prevents the granules from pouring into the airlock

chamber 7. The cryogenic liquid vapor penetrating under the overpressure into the container cavity leaves the nly channel 10 through the gas outlet. Overcoming the resistance of the spring, the slide-pusher 11 is retracted to the extreme rear position and secured with the help of the latch 12. granulated bioproduct, filling the space between the end of the shutter-pusher 11 and the rotary shutter 9. Intensive evaporation of the bioproduct is diverted through the channel 10.

Pull back into the rearmost position of the mandrel 3 and load it with the help of an elastic tensioning element 4. The working stem of the device is inserted into the cervical canal of the animal and press the trigger bracket b, acting on the retainer 12, which releases the shutter-pusher 11. 11, it triggers, pushes a portion of the bioproduct from the airlock chamber into the bore of the working shaft 2, from which the bioproduct is pushed out by the mandrel 3, which is activated by the elastic tension element 4 released by the clip 6.

The proposed device works quite reliably. In this case, irritation or burns of the mucous membrane of the cervical canal and the cervix of the animal are not allowed, and the sterility of the process is also required. All this greatly increases the effectiveness of insemination.

Claims (2)

1. A device for artificial insemination of animals, containing a working stem attached to the arms, inserted into the mandrel stem bore, and a magazine made in the form of a container for granulated sperm placed in a Dewar vessel with a cryogenic medium, characterized in that process by ensuring reliability of operation, the magazine is installed above the working barrel, the cavity of the container for granulated sperm being connected to the channel of the latter by means of a gas outlet channel spring-loaded shutter-pusher. 2. The device for artificial insemination of animals, made in the form of a container for granulated sperm, labeled in a Dewar vessel with a cryogenic medium, is distinguished by the fact that, in order to increase its performance, the store is equipped with a mesh cup, and granulated sperm is rigidly fixed along the axis of the net glass using radial ribs, and the cavity of the net glass is filled with a porous hygroscopic material impregnated with a cryogenic liquid. nineteen FIG. 2
