RU213595U1 - Device for inserting a gastric tube into animals - Google Patents

Abstract

The utility model relates to veterinary medicine, in particular to devices for introducing a probe into the esophagus, stomach or rumen of animals. The device for inserting a gastric tube into animals includes a ball made of soft rubber, in the center of which there is a large oval hole for introducing the probe and small holes for ventilation of the lungs. In this case, a metal elongated loop with a soft coating passes through the ball, having two free ends. One end of the loop serves to fix the device in the researcher's hand, and the other end to open the animal's oral cavity in order to insert the probe.

Description

The utility model relates to veterinary medicine, in particular, it is intended for introducing a probe into the esophagus, stomach or rumen of animals.

Currently, various devices are used in veterinary practice for introducing a probe to study the esophagus, stomach and rumen in animals. Most often, these devices are structures in the form of yawns, for example:

screw yawner for horses (Big Encyclopedic Dictionary: Veterinary Medicine. M., 1998 - S. 117);

simple yawner for horses (Big Encyclopedic Dictionary. Veterinary Medicine. M., 1998 - p. 117);

yawner loop-shaped for cattle (Big Encyclopedic Dictionary. Veterinary Medicine. M., 1998 - S. 117);

a yawner for expanding the oral cavity in animals (Author's St. USSR No. 17409, author Sharabin I.G. - 1935);

a sliding metal yawner for sheep, goats and young animals of other animal species (Author's St. USSR No. 119310, author Shaptal I.P. - 1957);

yawner for animals (Author's St. USSR No. 570362, author Kostyna M.A. - 1957);

yawner for animals (Author's St. USSR No. 542520, author Korikov P.N. - 1977);

a device for opening the mouths of animals (Author's St. 1181658, author Rantsan V.V. - 1985);

yawner for cattle (Author's St. 1674830, author Kyiv K.Ya. - 1991);

yawner for cattle (Author's St. 1748812, author Semenyutin V.V. - 1992);

special curly yawner for cattle (RF Patent for utility model No. 103728, author Korobov A.V. and others);

yawner (Patent of the Russian Federation for a useful model No. 48476, author Dzhavadov A.K. and others - 2005).

A common disadvantage of the above yawning devices is the complexity of the design, as well as the intended use for a specific type of animal or a certain age, which limits their use in veterinary practice.

The closest in technical characteristics to the proposed utility model and taken as a prototype is a device made in the form of a fragment of a pipe having a large diameter transverse round hole in the middle part (for inserting a probe) and small diameter holes for additional lung ventilation. At the same time, a metal rectangular loop is inserted and fixed inside the pipe fragment, having two free ends coming out of the pipe: one end serves to push the jaws apart, and the other is made in the form of a handle and serves to fix the device (RF Patent for utility model No. 197071. - 2020 Author Sein O. B. and others)

The main disadvantage of the prototype device is that during and after the introduction it can injure the mucous membrane of the oral cavity of the animal.

The technical objective of the proposed utility model is to create a device that eliminates the above disadvantages and provides a quick and painless introduction of the probe into the esophagus, stomach or scar of the animal.

In FIG. 1 shows a diagram of a device for introducing a gastric tube into animals; in fig. 2 (photo) shows the use of the device when inserting a probe into cattle.

The solution of the technical problem is achieved by introducing into the design an element made in the form of a ball 1 made of soft rubber, in the middle part of which there is a large through rounded hole 2, which serves to insert the probe, as well as small holes 3 for ventilation of the lungs of the animal. At the same time, a metal oblong loop 4 is passed through the rubber ball 1, covered with a soft shell 5 and having two free ends coming out of the rubber ball 1, which serve to fix the device in the researcher's hand and move the animal's jaws apart when the device is inserted into the oral cavity.

A distinctive feature of the proposed device is the presence of a rubber ball in its design, which has a large through hole for the probe and small holes for ventilation of the lungs when the device is in the animal's oral cavity. At the same time, the ball is made of soft rubber, which does not cause injury to the mucous membrane of the oral cavity during the introduction and fixation of the device. The presence of an elongated loop made of a metal rod prevents compression of the rubber ball by the jaws of the animal, and also serves to push the jaws apart when using the device and fix it in the researcher's hand. At the same time, the metal loop has a soft coating (rubber, Teflon), which also prevents injury to the oral mucosa.

An example of using the device of the claimed design. Before the insertion of the probe, the device is held by one of the ends of the loop 4, and the free end in a flat position is inserted from the side between the jaws of the animal. When the rubber ball 1 is placed between the jaws of the animal, the device is rotated around the axis to bring the loop 4 into a vertical position, and through a large through round hole 2 in the rubber ball 1, the probe is inserted into the pharynx and esophagus, and, if necessary, into the animal's stomach or scar.

This device is used in the educational process when teaching courses of therapy and surgery at the Kursk State Agricultural Academy named after I.I. Ivanova.

Claims (1)

A device for introducing a gastric tube into animals, comprising an element for opening the oral cavity of an animal with a through rounded hole for inserting the probe and smaller holes for ventilation of the lungs, and an oblong metal loop passed through the element for opening the oral cavity of the animal, characterized in that the element for opening the oral cavity the animal is made in the form of a soft rubber ball that can be placed between the jaws of the animal, and the oblong metal loop is provided with a soft coating, passed through the soft ball and has two free ends, one for fixing the device in the researcher's hand and the second for opening the animal's oral cavity when inserting the probe.
