Description

The utility model relates to medical equipment and is aimed at increasing the efficiency, reliability and convenience of drying, long-term storage of flexible endoscopes and similar channel products after treatment with high-level disinfection (hereinafter referred to as HLD).

A device is known for aseptic storage and drying of endoscopes, containing a compartment for placing endoscopes connected to holders, a group of compressors, the inlet of which is connected to air supply pipelines disinfected using bactericidal treatment, and the outlet is connected to holders to which endoscopes with the ability to supply disinfected air into the endoscope channel, as well as a system for taking air from the environment and supplying filtered air to the inlet of compressors (see patent RU 187267 U1, pub., 02.28.2019).

The disadvantage of the prototype in relation to the claimed technical solution is the insufficient level of TLD of endoscopes due to the storage of endoscopes in a horizontal position. Due to the lack of a drain hole in the storage containers and structural elements for air exchange, moisture will not be completely removed from the internal channels of the endoscopes and each container individually, which can lead to the proliferation of microbial cells.

The technical problem is to create a device for drying and long-term aseptic storage of endoscopes with a high level of TLD without the above disadvantages.

The technical result consists in increasing the efficiency of maintaining aseptic storage conditions of both the internal channels of endoscopes and the outer surface of endoscopes.

The problem is solved, and the technical result is achieved by the fact that in the cabinet for aseptic storage and drying of endoscopes, containing a compartment for placing endoscopes in it, laid out in a suspended state on roll-out holders, a group of fans and compressors, the input of which is connected to the air supply pipelines, disinfected by using filtration cleaning, and the output is connected to connectors to which endoscopes are connected with the possibility of supplying disinfected air to the channel/s of the endoscope, as well as a system for taking air from the environment and supplying filtered air to the inlet of compressors, according to the utility model, the compartment for placing endoscopes has side walls, ceiling panel and bottom, roll-out endoscope holders are located on guides in the ceiling panel and bottom with the possibility of placing endoscopes on them in a vertical position, the cabinet is equipped with a system for taking air from the environment and supplying filtered air into the internal cavity of the compartment for placing endoscopes with the possibility blowing the outer surface of the endoscopes with filtered air through the blowing holes of the compartment, as well as a system for releasing the air supplied into the compartment through the outlet holes; at the bottom of the compartment there are trays for collecting moisture displaced by disinfected air from the internal channels of the endoscopes, while the blowing and exhaust holes are made in opposite sides walls of the compartment for placing endoscopes, in the ceiling panel there are additional holes for blowing endoscopes with the possibility of supplying blown air along each suspended endoscope, above the ceiling panel there is a compartment for compressors and filtration of air taken from the atmosphere, and outside one of the side walls there is an air supply compartment for the placement compartment endoscopes.

The utility model is illustrated with the help of drawings.

in fig. 2 shows a view of the compressor compartment and filtration of air taken from the atmosphere;

in fig. Figure 3 shows a view of the ceiling panel from the endoscope compartment;

in fig. 4 - enlarged view A of FIG. 3;

in fig. 5 - general view with withdrawable holders mounted on guides.

The described cabinet contains a compartment 1 for placing endoscopes connected to adapters with connectors 2 and thus suspended in a vertical position on draw-out holders 28 mounted on guides 29. Compartment 1 has opposite side walls 3 and 4, as well as a ceiling panel 5 and bottom 6. The cabinet also has a compartment 7 for compressors and filtration of air taken from the atmosphere, in which there is a group of compressors 8, the output of which is connected to air supply pipelines 9, to which endoscopes with the ability to supply disinfected air into the channel of the endoscope/s. The cabinet also has a compartment 10 for supplying air to the compartment 1 for placing endoscopes. In the specified compartment 10 there is a system for taking air from the environment and supplying filtered air into the internal cavity of the compartment 1 for placing endoscopes with the possibility of blowing the outer surface of the endoscopes with filtered air through the blowing holes 11 of the compartment 1. The air intake system includes an air intake device 12 through which atmospheric air is sucked in by fan 13 through pipe 14 and supplied to the quick-detachable filter 15. From filter 15, fan 16 with a lower capacity supplies air to the distribution pipe 17 located along the side wall 3 of compartment 1, from which blowing air is supplied through inlet pipes 18 and holes 11 in compartment 1. Another one, ceiling fan 19, supplies air from the distribution pipe 17 into the cavity above the ceiling panel 5 for subsequent air supply into compartment 1 through additional blowing holes 20 made in the ceiling panel 5. The cabinet is also equipped with an exhaust system supplied to compartment 1 air through the outlet holes 21 made in the side wall 4 into the atmosphere. At the bottom 6 of compartment 1 there are trays 22 for collecting moisture displaced by disinfected air from the internal channels of the endoscopes.

The system for supplying disinfected air to compressors 8 contains a two-way valve 23, check valves 24, a tee 25, and a Midisart 2000 filter 26.

The cabinet is a metal structure assembled from sheet bent profiles and is used as follows.

To each connector 2 inside compartment 1, the endoscope is suspended vertically on a roll-out holder 28 mounted on the guide 29, and its internal channels are connected to the compressor 8 supply channel of disinfected air, which is used to blow through the internal channel of the endoscope, disinfect its internal walls and displace moisture from it into the tray 22, located at the bottom 6 of compartment 1. In this case, a separate compressor 8 operates for each suspended endoscope by connecting each connector 2 with a separate compressor 8.

The air intake system with the help of a fan 13 sucks in atmospheric air through the air intake device 12 through the pipe 14 and supplies it to the quick-detachable filter 15, from which the filtered air is supplied with the help of a fan 16 into the distribution pipe 17 located along the vertical side wall 3 of compartment 1. From pipe 17, filtered air is forced through the blowing holes 11 into compartment 1 at different levels along the height of compartment 1, blowing outside the suspended endoscope, cleaning it and creating an air curtain around the endoscope. Through the outlet openings 21 in the side wall 4, the filtered air supplied to the compartment 1 is released into the atmosphere.

In addition, from the distribution pipe 17, the filtered air is supplied by the ceiling fan 19 to the compressor compartment 7 above the ceiling panel 5, and from there is directed through additional holes 20 made in the ceiling panel 5. Next to each hole 20, a deflector 27 or a diffuser designed to deflect in a given direction the air supplied through hole 20.

Each compartment is closed by a door or lid, that is, the described cabinet is a closed container divided into compartments.

Hanging endoscopes in a vertical position, as well as connecting each endoscope to a separate compressor ensures guaranteed cleaning of its internal channels from moisture. An air curtain of filtered air completely envelops each endoscope, ensures cleaning of its external surface and creates its protection when the door of compartment 1 is open.

Under such conditions, the endoscope can remain in aseptic conditions for a long time, since the air pumped into compartment 1 is constantly exchanged.

Thus, the use of the described cabinet makes it possible to increase the efficiency of maintaining aseptic conditions of storage, drying and cleaning of both the internal channels of endoscopes and their outer walls and at the same time ensure long-term aseptic storage of endoscopes with a high degree of TLD.

Autonomous operation of the air supply or centralized air supply is possible, depending on the medical organization and the conditions for placing the cabinet.

The Cabinet can be designed as either stationary (door on one side) or walk-through (doors on both sides). The walk-through version of the Cabinet allows it to be installed as a partition between the compartment for HLD endoscopes and treatment rooms, which increases the convenience of its use and reduces the time spent on moving endoscopes between different stages of their processing and storage.

The Cabinet is powered from a single-phase AC network 230 V ±10%, frequency 50 Hz. The air flow passing through several stages of cleaning is created by a set of fans and compressors in the compartments, or is supplied centrally through a special adapter (external air supply system).

The time to establish the operating mode is no more than 336 hours (14 days) per position of the endoscope. The air supply passes with excess pressure to the chamber. Air flow 335-565 m ³ /hour depending on the model.

The criterion for the duration of the endoscope's stay in the Cabinet is the glow of the indicator strips both on the control monitor and on the external LED panel for 336 hours with a smooth color change from green to red. Uniform distribution of air with excess pressure in the placement chamber and timing for decreasing the selected position.

The working position of the Cabinet is vertical.

The cabinet user is controlled through software with the ability to configure individual parameters for each endoscope. Identification of endoscope data occurs through a special RFID tag, to which the storage parameters and labeling of the endoscope are linked.

Identification of user data occurs through a special magnetic card, to which the employee’s designations are attached.

After the storage time has expired, a receipt with the data and storage conditions of the endoscope is printed on the built-in thermal printer.
