X-ray installation for panoramic dental research

 

(57) Abstract:

The invention relates to a medical x-ray techniques. The unit can be used for examination of the maxillofacial Department head of the patient, mainly in specialized areas of residential buildings, institutions, automobile mobile dental office. The installation includes the fence, inside of which is placed the generator device and the vertical support with the console. On the console is installed emitter x-ray tube, includes made the anode is placed on the cassette tape. Fencing is made in the form of a portable casing from rentgenoprosracne material, wall or rack which is fixed to the console with the radiator. The design allows for pivoting movement of the console and the emitter in the vertical and horizontal planes independently of each other. The walls of the casing have moving parts, which in the closed position overlapping the fixed part of the casing wall, providing complete shielding of x-ray radiation. Cassette for x-ray film has a Central hole, and its dimensions are selected from both conditions and installation in particular, due to the ease of aiming. 2 C.p. f-crystals, 3 ill.

The invention relates to a medical x-ray technique and can be used for examination of the maxillofacial Department of the patient's head.

It is known that medical x-ray machines do not use in areas without special protection against radiation (Rechentechnik. Handbook edited by centuries Klyuyev, kN. 1, 1980, M, Corn-s, S. 57). In this regard, all these x-ray machines are used exclusively in specialized areas, ceiling, floor and walls which serve as a barrier from an unused x-rays.

Known dental x-ray tube apparatus comprising a generating device, the emitter x-ray tube and tripod, which is a vertical support mounted on it with a console. Generating device housed in the base, and emitter mounted on the console with the possibility of rotation around the vertical or horizontal axes. For a complete panorama of both jaws of the patient on the device, you must perform consistently 12-14 shots individual sites. When you run this diagnostic is high time and unreasonably high radiation load on the patient. - Rechentechnik. Handbook edited by centuries Klyuyev, M., Corn-s, 1980, vol. 2, S. 208.

These drawbacks are partially eliminated specialized panoramic x-ray machine adopted for the prototype. The installation includes a table that hosts the generator device with a remote control. On the nightstand fixed vertical support structure, consisting of columns and beam-console, which is fixed emitter x-ray tube. X-ray tube includes a hollow made the anode, on which is mounted a light-tight envelope that serves as a cassette for x-ray film. To obtain a snapshot of the patient's front teeth clamps the anode of the tube and presses his hands the envelope so that the latter covers one of the jaws. As in the analogue, the emitter mounted on the console with the possibility of rotation in the vertical plane. To bring the emitter to a predetermined position, the console is installed on the column at the desired height. Then the emitter is moved along the length of the console in a horizontal plane and rotation in the vertical plane around an axis fixed in its working position. - Rechentechnik. Handbook edited by centuries Klyuyev, M, core Department of the patient's head is rather long and tedious. To perform a panoramic study of both jaws required repeated adjustment of the position of the emitter. In turn, to perform this adjustment to the medical staff each time it is necessary to enter in the x-ray room and out of it, which further complicates the process of shooting.

The basis of the invention is the task of creating a portable x-ray equipment for panoramic dental research, providing the maximum possible simplification of its operation, in particular the simplification and acceleration of the aiming of the radiator when doing panoramic shots. An additional challenge is ensuring the possibility of obtaining a panoramic shot of both jaws at the same time.

The problem is solved in that in the x-ray machine for panoramic dental research, including the fence, inside of which is placed a generating device and a vertical support mounted on it with a console, which is equipped with an emitter x-ray tube, includes made the anode is installed on the cassette for x-ray film according to the invention fencing is made in the form of a portable casing from rentgenoprosracne mother is Uchitel installed with capability independent from each other pivoting movement in vertical and horizontal planes. In an x-ray machine portable wall of the casing are movable parts in the position they overlap the fixed part of the casing wall with capability of full shielding of x-ray radiation.

The best result is achieved if the cassette for x-ray film provided with a Central hole, and its dimensions are selected from a single full panoramic picture of both jaws.

The invention is illustrated in the drawings, on which:

Fig. 1 - declare install, isometric,

Fig. 2 - the same, lateral view,

Fig. 3 - the same, top view.

X-ray installation for panoramic dental research includes a casing 1 made in the form of cabins from rentgenoprosracne material. Inside the casing, for example, on the rack 2 hinged console 3 enabling its rotation in a horizontal plane at an angle = 45 deg. As the console can be used, for example, balanced parallelogram mechanism (Fig. not shown), providing turn the console in a vertical plane at an angle = 30 deg. At the free end of the console 3 is movable, for example, using wikispecial its rotation around its own vertical axis by the angle = 120 deg., and the method of attachment of the emitter 5 of the plug 4 provides its rotation in a vertical plane at an angle = 45 deg.

To put the anode 6 of the tube of the radiator 5 is mounted a cassette 7 with x-ray film. The cartridge 7 has a Central opening 8 and may be provided with a collet (Fig. not shown) for fixing the anode 6.

The casing 1 has a movable part. In particular, as shown in the illustrations, moving can be performed parts of the walls of the casing, connected to the front wall 9 of the casing, opposite the console 3. To move the movable sections of the walls of the housing unit can be fitted with guides 10 and rollers 11. In the closed position, the movable parts of the walls of the casing overlapping the fixed part of its walls "overlap" to ensure the full shielding unused x-rays.

The device operates as follows.

At the entrance of the patient movable part of the casing is extended by means of rollers 11 along the guide rails 10. The patient sits in the dental chair (Fig. not shown), and the medical staff prizelive emitter on the monitoring of the maxillofacial Department in the following way. The position of the emitter height predelay jaw angles , shall equal 0;

- when one of the side shots of both jaws angle left unchanged, and the corners and are selected depending on the diagnosed area of the jaws;

- when performing a panoramic shot only the upper jaw is determined by the angle .

Similar manipulations are made for precise aiming at all possible clinical situations.

After the final targeting the patient squeezes the teeth of the anode 6 and palms presses the tape-to-face.

Due to installation in portable (small form) medical staff, conducting aiming, can not enter the inside of the casing.

At the end of the preparatory procedures movable parts of the walls of the casing are moved to the closed position and is shot.

To exit the patient movable part of the casing is again moved into the "open"position.

Thus, the design of the inventive x-ray equipment in contrast to the known apparatus, operated exclusively in specialized areas, including unlike the prototype allows you to simplify and accelerate the alignment of the emitter, especially when the issue is intelligent snapshot of both jaws simultaneously in a single exposure.

The claimed invention is intended primarily for use in specialized premises: residential buildings, institutions, etc. in Addition, the invention can be easily installed in the vehicle mobile dental office.
