Description

The utility model relates to the field of medical technology.

The universal mobile x-ray apparatus (apparatus) is intended for radiographic examinations in medical institutions as a mobile fluorograph, ward apparatus, can be used in trauma and emergency departments, in addition, it can be used in non-stationary and mobile hospitals, as well as for providing medical care at home .

Currently, x-ray diagnostics in the country is in an extremely neglected state. A very difficult situation has developed in Russia with pulmonary diseases, in particular, with tuberculosis. Successful treatment of this disease requires early diagnosis. The neglected forms of tuberculosis are difficult to cure and extremely dangerous in terms of infection of a healthy population.

In the currently used direct current X-ray machines, progress is associated with the use of modern technologies for the manufacture of component parts, which make it possible to reduce the size of the X-ray focus and improve the detection efficiency. Registration systems do not use photostimulated phosphors, full-sized matrices of amorphous silicon due to their high cost. To bridge this gap, fundamentally new ideas and methods for creating X-ray diagnostic equipment are needed.

The closest analogue of the claimed utility model to us seems to be an X-ray machine with automated control "GEOLINK" ARA 110/160 [1]. The well-known mobile device, small-sized, characterized by a combination of properties

stationary devices with maneuverability and simplicity of wards. A constant voltage x-ray tube is used. The optimal operating modes of the apparatus are determined automatically after setting the patient’s organ from the control panel, introducing the category of patient completeness and focus-film distance. Actual shooting options are monitored using a digital display.

The disadvantages of this apparatus are:

- Change in the horizontal departure of the emitter when changing the height of the emitter;

- The need to simultaneously hold the tape measure to measure the distance to the cassette and position the device vertically and horizontally;

- For light illumination it is necessary to hold the button of the backlight and to position the device with the second hand;

- Weak lighting, partial dimming of the room is necessary;

- The control panel operates in the infrared range, which requires direct visual contact with the device;

- Mechanical lifting of the emitter;

- A programmer for adjusting the settings is not included;

- The small diameter of the wheels, which makes it difficult to enter the elevator and overcome the thresholds.

- There is no digital visualization system.

Coverage of the entire population with high-quality X-ray diagnostics is possible only with the help of an inexpensive, lightweight, compact one, which allows transportation of X-ray equipment by any means of transport. Foreign equipment is not suitable for this purpose because of the high cost and non-compactness.

The technical result of the proposed utility model is that the developed digital visualization system can be applied without redesign (upgrade), the apparatus has a cost at the level of film systems, a low dose of radiation, as well as minimal weight and dimensions.

The proposed universal mobile x-ray apparatus contains a movable tripod with a handle for transportation, a radiator, a control panel. In contrast to the closest analogue, the movable tripod has a device for lifting the emitter with an arrow based on an electric drive, a device for changing the tilt of the arrow with a balancing and fixing system, a device for turning and fixing the plug of the emitter, and the emitter consists of a sharp focus nanosecond pulsed x-ray tube, a 2-stage generation system , backlight devices with automatic shutdown of the light bulb, laser range finder, radiation aperture device, shutter rotation device. The apparatus contains a digital imaging system with a CCD photodetector array with a control circuit.

In 1992, at the Institute of Electrophysics, Ural Branch of the Russian Academy of Sciences, a new principle of current interruption in powerful pulse systems with inductive energy storage was discovered. Using it allowed us to develop a fundamentally new portable x-ray diagnostic apparatus, characterized by low cost, small dimensions, low dose level, which is confirmed by numerous tests. Together with the Electrokhimpribor combine, an original X-ray sealed tube was created for the device with a working life of more than 50,000 images and high stability of X-ray radiation.

Digital imaging system (Figure 3) is designed to control, visualize, register and process shadow images obtained when performing x-ray

studies of human internal organs. The digital imaging system allows for effective management of the X-ray machine and related equipment, increases the usefulness of X-ray diagnostics, as well as the productivity and quality of diagnostics, and helps to reduce the patient's effective radiation dose during the study. Using a digital imaging system makes it possible to create an electronic archive of x-ray studies, as well as transferring images by electronic means of communication without loss of image quality. It becomes possible to use computer diagnostic methods based on pattern recognition systems and recording the dynamics of the processes under study.

The digital imaging system (Figure 3) includes the following components: luminescent screen 1; digital camera 2, lens 3; a CCD photodetector array with a control circuit 4; analog-to-digital converter 5; computer exchange interface 6; Computer (PC - compatible computer); software.

The digital visualization system provides: control of the position of the radiation source and control of the geometry of the x-ray beam for compliance with established requirements; radiation source control; determination of the state of the radiation source; determination of the estimated effective dose of radiation received by the patient; digital camera operation management; determination of camera status; Contrast media administration for angiographic studies maintaining a database of patients, visits, exposures and images protected from unauthorized access and changing with the calculation of the received effective doses of x-ray exposure, to protect against unauthorized

access system must have three access levels, protected by the passwords “service engineer”, “doctor”, “laboratory assistant”; maintaining information about the laboratory assistant who performed the study and the doctor who referred the patient to the study and made an opinion on the results of the study; input to the computer and output to the monitor screen of dynamic and static digital images and their recording in the database on the computer hard drive and / or on a dedicated database server; storing on the monitor screen the last or any arbitrarily selected frame of digital images; recording and playback of the sound commentary on the images, input of the sound commentary should be carried out by means of a microphone connected to a computer, program setting of time and recording quality of the sound commentary is provided.

The minimum dimensions and weight of the claimed utility model make it possible to place it in the trunk of a car, serve by one person. The device uses a modern computer control and data processing system. The absence of wires between the generation, visualization system and the computer greatly simplifies the work of the operator. Data transmission via radio and the Internet allows you to use the device in almost any hard-to-reach and remote places, as well as in trains, on ships, in airplanes. The device allows for any type of general x-ray diagnostics.

The advantages of the device are

- Application of hard shooting techniques;

- Use of an electric drive to lift the emitter;

- The use of automatic shutdown of the backlight;

- The use of a laser rangefinder from the emitter to the cartridge;

The use of a "cold" cathode, which allows tens of times to reduce the mAc through the tube to minimize the preparation time for shooting (1 minute or less);

- The remote control works in the radio range, direct visibility between the receiver and the emitter is not required;

- The transport and working dimensions differ only in the positioning of the emitter. When the radiator is folded, the device easily fits in the passenger elevator together with the operator;

- Wheels of a large (125 mm) diameter;

- A digital visualization system has been developed for the device, which can be applied without redesigning (upgrade).

- 1.5-2 times lower cost compared to the closest analogue.

The cost of the device developed by DATA-CENTER X-Ray (Yekaterinburg) is 2-3 times lower than the cheapest digital x-ray systems on the market today. Thus, the device combines modern digital visualization, low cost at the level of film systems, low radiation dose and minimal weight and dimensions.
