RF No. 39490 U1, class A61L 2/10, 2004). This device is the closest analogue.

However, the known device also does not meet the requirements of modern medical institutions, since not all medical devices can be stored under direct UV radiation without being destroyed. This device does not provide storage of long hollow instruments, including endoscopes, and medical materials that must be sterile stored without the damaging effects of UV radiation.

The technical result of the utility model is to expand its functionality of the device by expanding the range of medical products and materials subjected to storage, to increase the quality of storage, as well as to increase the usability of the device.

The technical result is achieved by the fact that in the device for storing sterile medical devices containing a housing consisting of two compartments, in the first of which there is a grating for placing medical instruments, and in the second there is a bactericidal UV lamp, an electronic unit connected through a unit power supply with a mains switch, and a circulation fan, the casing is made in the form of a two-leaf metal cabinet with hinged transparent glass doors, the left wall of the first compartment of the cabinet is made stationary, and the right wall of its second compartment is removable and l-shaped, a separation partition is placed between the compartments, additional grilles are installed in the first compartment to accommodate medical instruments and materials, as well as brackets with nozzles for attaching endoscopes, rubber hoses and other long hollow medical devices, an additional bactericidal UV lamp, a compressor with a receiver equipped with a valve block, a supply fan with a casing, a heating element, door docking sensors connected to the halogen lamp connected to the power supply unit and a removable wall closed state sensor connected to the power switch, while the circulation and supply fans are equipped with filters, transparent glass windows are installed in the dividing wall opposite the bactericidal UV lamps, and an air channel is made, and the electronic unit is made in the form of interconnected control panel with switches, information board and microprocessor with built-in timers, which is performed En with the ability to control the operation of bactericidal UV lamps, compressor, heating element, circulation and supply fans.

In addition, polycarbonate with a layer of protection against hard UV radiation from bactericidal lamps was used as transparent glass for doors and windows.

In addition, reed switches are used as sensors for connecting the doors and the closed state sensor of the removable wall.

In addition, the number of valves in the valve block of the receiver, the number of switches on the control panel and the number of microprocessor timers correspond to the number of endoscopes.

In addition, the receiver is equipped with a built-in bactericidal UV lamp.

The device comprises a metal case in the form of a double-wing cabinet with hinged doors, the left wall of which is stationary, and the right is removable and has a L-shaped shape. The cabinet consists of a compartment of the working area for placement of previously sterilized or disinfected medical instruments and materials and a technical compartment in which technical components and controls are placed. The cabinet doors are made using transparent glass for visual observation of the instrument, which has the property of not letting in the ultraviolet part of the radiation, or polycarbonate with a layer of protection against hard UV radiation from a bactericidal lamp (lighter than glass, more resistant to impact). Bactericidal lamps located in the technical compartment are a source of UV radiation. Fans, also located in the technical compartment, are designed to force air circulation and create excessive pressure inside the device. To clean the air flow, the fans are equipped with dust filters. The technical compartment contains a compressor and a receiver (with a UV lamp integrated into it) used to purge the internal cavities of endoscopes. The working area and the technical compartment are separated by a metal partition with transparent windows for visual monitoring of the health of UV lamps. Due to the removal of UV lamps, direct UV radiation does not enter the working area into the technical compartment, therefore, the device can store medical instruments and materials that could be destroyed under its influence, such as: endoscopes, rubber products, sterile gauze, etc. d. Access to the tool for placement and fence is carried out by opening one of the doors of the device.

The essence of the claimed device is illustrated by drawings, where in figure 1, figure 2 and figure 3 shows a device with basic elements (the device is shown with the doors open); figure 4 shows a device in section with the direction of flow of disinfected air; figure 5 shows a functional diagram of the device; figure 6 shows a block diagram of the algorithm of the device.

The device comprises (Fig. 1 ÷ 4) a housing consisting of a compartment of the working area 1 with lattices 7 located therein for accommodating sterile medical instruments and materials, an arm with nozzles 6 for attaching endoscopes, rubber hoses, and other long hollow instruments and materials, halogen lamp 19, left door 8, right door 9, door limit switches - sensors 21 for connecting doors (reed switches) and valve block 29, as well as from technical compartment 2 with technical components of the device, left stationary Coy 3; the right removable wall 5 with a network switch 18, a control unit in the form of a microprocessor 17, an information board 25, a control panel 26; between the working area 1 and the technical compartment 2 there is a dividing wall 4 with visual inspection windows 13 and an aperture of the air channel 12. Figure 3 shows a device without a right removable wall 5 for servicing the technical compartment, in which there are electrical components: a circulation fan with a filter 10 , heating element 16, UV germicidal lamps 15, supply fan with filter 11, supply fan casing 14, compressor 20, technical compartment limit switch - closed-state sensor 22 is removable wall (reed switch), receiver 23 with a UV lamp 24 located inside it, power supply 27, fuses 28, temperature sensor 30, receiver pressure sensor 31.

The principle of operation of the device is as follows.

Sterile instruments for storage and drying are placed in the working area 1 of the device as follows: small medical instruments and materials are placed on the grids 7, and long, hollow medical instruments: rubber hoses, plastic tubes and endoscopes are attached to the nozzles of the bracket 6. In the operating mode of the device, the tool is stored and dried due to the directed movement of the disinfected and heated air inside the device. Figure 4 shows the direction of air flow. From the working area through the opening of the air channel 12, the air enters the bactericidal UV lamps 15, where it is cleaned of bacteria, viruses and other microorganisms, then the air enters the heating element 16, where it is heated and under the influence of a circulation fan with a filter, the air is pumped in the working area of the device 1 and in the hole of the bracket with nozzles 6. Then, through the nozzles, air enters the internal cavities of rubber hoses, tubes, etc. The disinfected air enters the internal cavities of the endoscopes through the valve block 29 from the receiver 23, inside which a bactericidal UV lamp 24 is placed for additional air disinfection. The excess pressure in the receiver 23 is pumped by the compressor 20. The maximum number of stored endoscopes corresponds to the number of valves in the valve block 29. Medical instruments and materials are stored in the device with doors 8 and 9 closed, to prevent dirty air from entering through the slots, an excess pressure is created inside the device by the supply fan with the filter 11 through the technical compartment 2. To give the supply air flow direction to the germicidal UV lamps 15, a fan casing 14 is used. By removing bactericidal UV-lamps with hard radiation from the working area, it becomes possible to store and dry plastic and rubber products in the device that are destroyed under their influence. For visual monitoring of the health of UV lamps, windows 13 are used on the dividing wall 4. Through the transparent door 9, in the closed state of the cabinet, you can monitor the operation of UV lamps that are opposite these windows. Polycarbonate is used as transparent glass, which protects against the penetration of UV radiation from the technical compartment into the working storage area of the tool. On the right removable wall 5 are the device controls: a network switch 18 and a microprocessor 17 (with internal timers), an information board and a control panel (contains switches and buttons). For maintenance and repair of device elements located in the technical compartment, the right removable wall 5 is dismantled, as shown in Fig.3.

The algorithm of the device and the interaction of its elements is illustrated by a functional diagram (Fig. 5) and a block diagram of the algorithm of the device (Fig. 6). When servicing the device after removing dust from the filters of fans 10, 11, UV lamps 15, 24 and treating the device with disinfectant solutions, it is necessary to tightly close the technical compartment 2 in order to reliably close the limit switch of the technical compartment - to activate the sensor 22 of the closed state of the removable wall (reed switch), then you must connect the device to the power supply and turn on the power switch 18. The microprocessor 17 will test the state of the buttons and switches of the control panel 26 and issue the appropriate commands and the information panel 25, and also supplies the supply voltage to the UV lamps 15, 24 and fans 10, 11. When the power switch 18 is turned on, the heating element 16 and compressor 20 will also turn on, the heating temperature is controlled by the temperature sensor 30, and the pressure inside the receiver 23 is pressure sensor 31. To bookmark or store medical materials and instruments, it is necessary to open door 8 or 9, and one of the sensors 21 for connecting the doors will work and voltage will be applied to the halogen lamp 19. Small-sized medical devices the instruments and materials are placed on shelves in the form of metal gratings 7. Long medical instruments, including endoscopes, are placed on a special bracket 6. When storing an endoscope, it must be connected to the fitting of one of the receiver valves and the corresponding microprocessor timer must be activated by turning on the corresponding control panel switch 26, the valve will open and heated and disinfected air will enter the endoscope cavity from the receiver, and the microprocessor will monitor this process and the information will be displayed on the bulletin board 25. Number of endoscopes must match the number of switches on the control panel 26, the number of microprocessor and the number of timers receiver valves.

During operation, the total operating time of the UV lamps is 15, 24, and if the time does not exceed the permissible operating time (8000 hours), the special LED "UV lamps are not finished" on the information board 25 lights up in green, if exceeding the norm, another LED “It is necessary to replace the UV lamps” lights up in red. This happens as follows: each time the UV lamps are turned on, the lamp operating time is counted by the internal timer for operating the UV lamps with the cumulative result recorded in the microprocessor buffer, while the latter gives a signal to the green LED “UV lamp operation is not finished”, when filling buffer (8000 hours of operation), the microprocessor generates a switching signal, as a result of which the red LED “Need to replace UV lamps” lights up.

After replacing the UV lamps, it is necessary to reset the timer by pressing the "Reset UV lamp hours timer" button. As a result, the signal is sent from the button to the microprocessor, which resets the internal timer for operating the UV lamp and switches the signal from the red LED “It is necessary to replace the UV lamps” to green “Operation of the UV lamps is not finished”, and the timer starts a new countdown of the operating hours of the UV lamps .

Due to the specified organization of the device provides:

- improving the quality of storage of medical supplies with the ability to control the storage process,

- expansion of the range of medical products and materials subjected to sterile storage without damaging effects of UV radiation,

- improving the usability of the device.
