SU36587A1 - Compression Dosing Apparatus For Radiology - Google Patents

Description

In the study of x-rays of the abdominal region using the method of compression, giving up and soft parts. This method allows for reduced x-ray scattering. In addition, in recent years, compression has been used to study the CJLiS of the gastrointestinal tract. Existing for this purpose, the device of the German radiologist prof. Shaul Oblag gives the largest drawbacks and therefore it is extremely inconvenient to use. The instrument, Shaul, is a re: zubo bubble inflated by a double balloon. This bubble is attached to the body of the patient with a linen bandage. During operation, the bubble is displaced, the jet requires interrupting work, lighting the darkened room and re-starting the instrument. In addition, the Shaul bladder, having no solid-crush, swells toward the patient and / or him. Compression is reduced, between patients to the screen) a large space is created, which is reflecting the sharpness of the image. .- -. h ,

in the device, according to dd, i, these flaws are warned. FIG. one

- ---. - - 1-, g,

u -: shows a side view of the device in section; in fig. 2 - view it from above.

The device for dosing koofessions at X-ray diagnostics consists of a petacle plate 1 transparent for peHTfeHOBiiix rays, to which it is air-permeable, with an narrow metal frame, the plate 3 is attached with an elastic, slightly X-ray-penetrating, elastic. The rubber 3 is bonded using the above-described metal frame 2 together with the four-leaved frame 4 surrounding it of lead, impermeable to x-rays, rubber. The transmission between the plate 1, which serves as the basis for the device, and the rubber plate 3, communicates with the outside air by rubbing the rubber tube 5. The latter is not connected to the pressure pump 6, which is provided with a valve 7.

When air is pumped by means of a pump 6, the rubber plate 3 protrudes in the form of the walls of the cylinlint and falls down again if the valve 7 is opened. The described device does not attach to the patient, but is fixed on any screen for X-ray. and moves in all directions along with n: the last. When you sell books

plate 3 opens the casement frame 4 of; lead rubber and puts their first pHHFlHKyji pHP to the patient's body surface. This, so-called anterior tydyc, serves to reduce x-ray scattering. When using the proposed device, the screen with which this device is connected is fixed, and the rubber is blown out, which squeezes another desired degree of the object to be examined. If it is desirable to fix the obtained picture on a film, then a cassette is inserted into the groove located between plate 1 and the screen and, without changing, the X-ray diffraction pattern is taken. Having made - a cassette containing four films at once, it is possible to produce a series of radiographs with dosed compression from one and the same object. Thus, the proposed device has known advantages over the above-described Shaul device.

1. Device for dispensing; X-ray compression technique, consisting of a x-ray-transparent plate, characterized in that an air-tightly attached frame 2 elastic frame is attached to it, an X-ray plate 3c surrounding it with a four-fold frame 4 of lead film, which is free for body radiation, an X-ray plate 3c. .WL.

2. Form of completion of the aforementioned c. Item 1 of the device, characterized in that in order to open the framework of frame 4, a cavity formed between PD asthms 1 and 3 is communicated by wiping the rubber pipe 5 with the Hi-1 supercharger pump 6 and the valve for air release.
