SU398249A1 - DEVICE FOR FETAL EXTRACTION IN AGRICULTURAL ANIMALS - Google Patents

Description

This invention relates to the field of veterinary medicine.

YcTpoiicTBo is known for extracting nlod from farm animals, for example, cows, consisting of a pipe with an emphasis at the abnormal end, and at the rear traction mechanism with barrels fixed to the limbs of the fetus.

When working with a well-known obstetrician, the obstetrician holds both hands and he cannot independently control the emergence of the fetus from the birth canal and provide it with the necessary assistance both in the birth canal and in its exit from them.

In order to increase convenience in working at the rear end of the pipe, a telescopic support column is installed in the proposed device. In this case, the emphasis is made in the form of a two-armed lever with a fork, which is hinged on the pipe and fixed in the working and non-working position.

The drawing shows the device, side view.

A device for extracting fruit from farm animals consists of a pipe /, an emphasis 2, made in the form of a two-arm lever with a fork, at the ends of which are fixed sidewalls 3 with upper and lower belts 4 and 5. The stop 2 is hinged at the end of the pipe. The short end of the stop through 6 is connected with the o-ring / installed inside the pipe /. The slider 7 has a movable retainer (S, with which the stop 2 is fixed in the working position. At the other end of the pipe, the traction mechanism consisting of a winch 9, a removable ratchet handle 10, a pawl // for fixing the winch and two cables 12 is mounted. The traction mechanism is mounted on a non-redundant frame 13, which is fixed to the pipe / by means of a bolt 14.

A telescopic strut 17 with two self-adjusting wheels 18 is attached to the movable bottom frame with an ocii 15 and a latch 16. The telescopic strut is mounted at a height of a fixture 19. On the pipe / there is a tent 20 with a repair hinge attached to the telescopic rack when assisting the lying animal and Iri transport device posit.

When working with the device, the stop 2 is rotated to the perpendicular position to the pipe / and is fixed in this position by the retainer 8 of the slide 7. If the animal is standing, then the sides 3 of the stop 2 with the upper repair 4 are placed on the bottom of the croup and strengthened by the bottom belt 5, which brings t under zhpvot animal 11 button. Then detach the trench belt 20, the telescopic rack / 7 is converted to a vertical

it is fixed with a fixture 16. The pipe / is lifted to the required height with the help of a telescopic stand and held in this position with a clamp 19. A loop of cables 12 is fixed on the legs of the knot above the chick joint and by swinging the handle-trendz 10 with one hand winding the cables 12 on the winch 9 and remove the fruit from the chickens. With the other hand, the fruit is corrected and supported.

If the animal lays down, the telescopic strut 17 is folded and attached to the tube / strap of the tripod 20. During the delivery of animals B to the lying position, assistance can be rendered without tilting the sidewalls 3 and without using the straps 4 and 5.

To translate the device into transport position, the latch 8 of the slide 7 is released, the stop 2 is placed on the pipe / and locked in this newly formed latch 8. The sides 3 with the belts 4 and 5 are folded, the ratchet handle 10 is placed parallel to the pipe. If necessary, the device can be sheathed. The device is transported by one person.

During manufacture, the length of the ratchet handle is calculated in such a way as to provide a tractive force of at least 260 kg.

The device allows one veterinary worker, livestock specialist or trained breeder to provide effective assistance to animals during difficult childbirth, while preserving the life of the mother and the nlod.
