Description

The utility model relates to veterinary radiography, namely, to conduct radiographic images in animals. The most effective use of this cartridge when removing from it an x-ray film for photo processing.

A cartridge is known, which, using a sealant and elastic locks, creates uniform contact between the reinforcing screens and the film, which ensures copying of the image from the fluorescent screens to the film (1).

Known cartridge, consisting of a cover, a housing and reinforcing x-ray screens. The case is a frame covered with duralumin sheet. On the lid, on the one hand, there are loops connecting it to the body, on the other hand, a rotary lock with a spring (2).

A flat cartridge is also known, which has a body — a front radiolucent wall and a metal edging, and a rear wall — a cover with locking locks (3).

A disadvantage of the known cassettes is the inconvenience and difficulties arising from the extraction of the x-ray film from them. In addition, a properly executed x-ray should have the designation "L" - the left side and "P" - the right side. For this purpose, metal letters are placed on a cassette with a film, which are stacked randomly and are not fixed, as a result of which they do not have a stable position. Each time these letters are to be removed from the cartridge, all this takes extra time and, in addition, the letters are often lost.

The objective of the proposed solution is to simplify the process of extracting an x-ray film from a cassette while maintaining its quality and integrity of the reinforcing screens, as well as simplifying the process of identifying the sides of the x-ray.

The task is achieved due to the fact that the cassette for radiography, containing two reinforcing screens, a housing connected by two hinges with a lockable lock cover, according to the invention, in the side of the housing there are two through holes glued with velvet for light insulation, for a lever located outside the cassette and fixed the transverse axis in the side of the case, in addition, it is connected to two platforms in the form of the letters "L" and "P" located inside the case at the corners of one of the short sides of the X-ray an aphic film.

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

- in figure 1. - cassette with X-ray film lifter (general view);

- figure 2. cartridge before removing the film (cross section);

- figure 3. cassette at the time of film extraction (cross section).

The cassette has two reinforcing screens 1 of the housing 2, connected by two loops 3 with a cover 4, lockable by a lock 5. In the side of the housing 2 there are two through holes 6 glued for velvet insulation, necessary to install the lever 7, which is fixed by the transverse axis 8 and is located outside cassette. Inside the case 2 of the cartridge near the holes b there are two platforms 9 in the form of the letters "L" and "P", which lie at the corners of one of the short sides of the x-ray film 10. The platforms 9 are connected to the lever 6.

The device operates as follows:

After laying the x-ray film 10 in the casing 2 of the cassette, it is closed with a lid 4, which is fixed in this position by lock 5 and an x-ray of the diseased animal is performed. In the room for the chemical processing of the film 10, the cartridge lock 5 is opened and pressure is applied (the direction of application of the force is shown by the arrow in FIG. 3) on the lever 7, which rotates on the transverse axis 8 and the platforms 9 lying at the corners of one of the short sides of the radiographic the films 10 are lifted, carrying the film 10 upward above the upper part of the cassette body 2.

After that, the x-ray film 10 is available for easy removal from the cartridge.

The extraction of the X-ray film 10 occurs smoothly, without jerking, leading to a violation of the integrity of its emulsion layer, to scratches and bends of the reinforcing screens of the cartridge. After removing the x-ray film, the lever 6 is released, and the device for removing the x-ray film spontaneously takes the position shown in figure 2.

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

- simplification of the procedure for designating the sides of the radiograph ("L" - the left side and "P" - the right side);

- simplification of the process of extracting x-ray film from the cartridge;

- preventing the formation of defects on the film when it is removed from the cartridge;

- maintaining the integrity of the reinforcing screens. This contributes to the implementation of x-ray images of good quality (see table).

As can be seen from the table, the application of the proposed utility model eliminates the formation of defects on the film and the reinforcing screens of the cartridge.

The proposed utility model was successfully applied in radiography of the peripheral skeleton of 16 dogs and 6 cats on the basis of the medical and diagnostic veterinary center Orel GAU.
