Abstract

The utility model relates to veterinary radiography, namely, to conduct radiographic images in animals. Its most effective application when laying the animal on the table deck. The objective of the proposed solution is to eliminate these disadvantages. The task is achieved due to the fact that the table for the radiography of small animals containing a fixed deck, according to the invention, in the deck on top there is a rectangular groove having a bottom and corresponding to the parameters of the radiographic cassette for radiography 1/2 of the body of a large dog, in addition, the groove is located the long side parallel to the long side of the deck and in the center of one of its halves, while the groove is equipped with corrective frames corresponding to a specific cassette size, and the groove depth is equal to and the thickness of the cassette and the correction frame when placed flush with the surface of the deck. The proposed utility model allows to achieve alignment of the upper plane of the table-cassette complex without complicating the design and increasing the cost of the table, eliminating geometric blurring of the image, the absence of cassette displacement relative to the studied area of the animal’s body and emitter, eliminating discomfort, pain in the fracture area of the animal when laying it on cartridge, preventing mechanical effects on the emerging bone marrow during x-ray assessment of the quality of osteoreparative. The proposed utility model was successfully applied in radiography of the peripheral skeleton of 11 dogs and 3 cats on the basis of the medical and diagnostic veterinary center of Oryol State Agrarian University.

Description

The utility model relates to veterinary radiography, namely, to conduct radiographic images in animals. Its most effective application when laying the animal on the table deck.

Telecontrolled tripods are known in which the emitter is in front of the patient and the table deck, and the radiation receiver is behind the deck (1).

Known tables, consisting of a deck on which the patient is laid, bases, grids for photographs, mechanisms for moving the deck and grill, fixing and other devices (2).

The main disadvantage of such tables is their complex design, which is necessary for comparing in one projection the emitter, the studied area of the body and the cassette with the X-ray film, as well as their high cost and bulkiness. In addition, one of the important requirements for a table deck is its manufacture from X-ray transparent materials. The X-ray transparency of the table deck depends not only on the type of material from which it is made, but also on its thickness.

An X-ray examination technique is also known, in which a cassette with a film is placed on a table directly under the animal, under the study area (3).

A disadvantage of the known method is that the cartridge is placed directly on the table and rises above its surface to its entire thickness. When laying the animal on the cassette, the part of the body selected for X-ray examination rises above the table surface and this to some extent prevents its closer contact with the cassette - the geometric blur of the image increases. And the desire to firmly press the studied part of the body to the cassette causes discomfort, anxiety in the animal, which, when trying to stand up, can shift the cassette relatively

emitter and even throw it off the table. Moreover, with the X-ray confirmation of the diagnosis of “bone fracture”, such styling can increase pain in the animal, lead to additional displacement of the fragments and damage to them by the sharp edges of blood vessels, nerves and other soft tissues. It is also undesirable to place the cassette on the cassette towering above the table deck and under X-ray control of the process of osteoreparation carried out by the researchers systematically (repeatedly) during the entire period of bone marrow formation in experimental animals.

The objective of the proposed solution is to eliminate these disadvantages.

The task is achieved due to the fact that the table for the radiography of small animals containing a fixed deck, according to the invention, in the deck on top there is a rectangular groove having a bottom and corresponding to the parameters of the radiographic cassette for radiography 1/2 of the body of a large dog, in addition, the groove is located the long side parallel to the long side of the deck and in the center of one of its halves, while the groove is equipped with corrective frames corresponding to a specific cassette size, and the groove depth is equal to and the thickness of the cassette and the correction frame when placed flush with the surface of the deck.

The technical essence of the proposed cartridge is presented in the drawing, where:

in figure 1. - X-ray table with cartridges of various sizes and a set of corrective frames (general view).

The table for the radiography of small animals has a fixed deck 1, in which a groove 2 with a bottom for the radiographic cassette 3 is made on top, while the groove area is adjusted if necessary with frames 4.

The use of the utility model is described by the example of radiographic confirmation of the diagnosis of a dog’s “femoral fracture” and is carried out as follows:

An X-ray cassette 3 is placed in the groove 2 of the stationary deck 1 of the table. The animal is placed on the deck 1 of the table parallel to its long axis, while the front of the body is placed away from the groove 2 with the cassette 3 flush with the surface of deck 1, and the damaged hind limb stack directly on the cassette 3. After this, an x-ray is performed.

If an X-ray examination is necessary, for example, bones of the chest limbs or skull, then the front of the animal’s body is placed on that half of deck 1 of the table where groove 2 with cassette 3 is located.

If it is necessary to use the cartridge 3 smaller than the groove 2, they resort to reducing its area by means of a frame 4, which corresponds to a certain size of the cartridge 3 and is inserted into the groove 2, and after that - the cartridge 3. In this case, the frame 4 and the cartridge 5 are placed in groove 2 flush with the surface of deck 1 of the table.

The application of the proposed utility model provides the following advantages:

- alignment of the upper plane of the table-cassette complex without complicating the design and increasing the cost of the table;

- elimination of geometric blurring of the image;

- the lack of displacement of the cartridge relative to the investigated area of the body of the animal and the emitter;

- elimination of discomfort, pain in the fracture zone of the animal when it is placed on the cassette;

- prevention of mechanical effects on the emerging bone marrow during x-ray assessment of the quality of osteoreparation.

The proposed utility model was successfully applied in radiography of the peripheral skeleton of 11 dogs and 3 cats on the basis of the medical and diagnostic veterinary center of Oryol State Agrarian University.
