Description

The utility model relates to medical equipment and can be used in devices for pre-sterilization cleaning of medical instruments by the combined action of a working solution and ultrasonic vibrations (from biological, mechanical, medicinal and other contaminants), which is an important step in preparing medical devices for sterilization.

A device for ultrasonic cleaning, in particular, of medical instruments, comprising a bathtub equipped with a lid filled with a liquid and a container placed in it, an ultrasonic oscillation generator and a cleaning process control system is known. Contaminated products are loaded into a container, which is placed in a bath pre-filled with liquid. Set the processing modes that provide when starting up the device to work, the parameters of ultrasonic cleaning (RU 2184625 2002). In the known device does not provide funds that would allow for high-quality cleaning of medical instruments having internal channels and cavities. In addition, the device is inconvenient to maintain and inefficient due to the fact that it does not use tools that ensure the injection of washing liquid into the bath.

A device for ultrasonic cleaning of medical devices, comprising a body with a radiation source located inside it, a bath with a disinfectant liquid, an ultrasonic oscillator with an exciter of these vibrations mounted on a bath with a disinfectant liquid, a pump system for pumping liquid, a process control system. Contaminated objects (medical instruments) are loaded into a cassette, which is placed in the processing chamber. The control panel sets the processing mode of the tools, in particular

the amplitude of the ultrasonic signal, its frequency and time of the U3-processing. The cassette with the instruments is lowered into the bath, where the U3-processing takes place. After the U3 treatment, the tools are moved to the washing bath, where due to the operation of the pump, they are washed (RU 2017499 1994). The known device does not provide sufficiently high-quality pre-sterilization cleaning and disinfection of medical instruments having various configurations and especially instruments having internal channels and cavities.

The closest analogue to the claimed device is a device for pre-sterilization cleaning of medical instruments containing a housing with ultrasonic generators located inside it, heating elements for a liquid, a liquid container installed in the housing, a metal mesh basket for placing the instrument, configured to be placed in a liquid container, nozzles for flushing (cleaning) internal cavities in medical instruments, a fluid or solution supply system to the washing zone, control panel (information is available on the website http://www.medisafeuk.co.uk). In the known apparatus, nozzles for flushing internal cavities in medical instruments are mounted on a removable mesh basket, which on the one hand complicates the maintenance of the apparatus (including the need to connect the nozzle manifold to the fluid supply system each time after installing the basket with the instrument in the container) and on the other sides - increases the risk of injector injuries when loading medical instruments to be cleaned into the basket. The use of a powerful pump with a complex valve-controlled system in the apparatus significantly increases the cost of the apparatus, which does not make it possible to use it in any medical institutions (including those with limited funds for the purchase of such equipment), and when the pump fails performing all cleaning operations. The presence in the device of one control panel can lead to erroneous inclusion by the maintenance personnel of an unnecessary operation and, as a result, to the possibility of malfunctions.

The inventive utility model is aimed at solving the problem of developing such a device for pre-sterilization ultrasonic cleaning

medical instrument, which, while ensuring the proper quality of pre-sterilization cleaning, will be available for use in any medical institution.

The technical result that can be achieved by using the claimed utility model is to increase the reliability of the device in operation, including by reducing the possibility of damage to the nodes of the device when loading medical instruments, to reduce the cost of the device, and to simplify its maintenance.

To achieve the specified technical result, a device for pre-sterilization ultrasonic cleaning of a medical instrument is proposed, which comprises a housing with ultrasonic generators and heating elements located inside it. A liquid container with a lid is installed in the housing. To place the tool, a metal mesh basket is used, made with the possibility of installation in a liquid container. To ensure flushing (cleaning) of internal cavities in medical instruments, nozzles are used in the device, which are mounted on the side wall of the container and equipped with flexible hoses for connecting cavity instruments. Three pumps are provided in the device, one of which is used to draw water into the tank, the second to collect the solution into the tank, and the third to supply detergent from the tank to the nozzles. The device has two separate (stand-alone, working independently from one another) control panels located on the wall of the case, one of which serves to control ultrasonic processing and temperature conditions, and the other to control operations for the collection of water and solution and to ensure the necessary concentration of the solution in washing liquid, as well as hydrodynamic treatment (washing the internal cavities of the instrument with a solution (washing liquid) supplied under pressure through hoses).

Installing nozzles (with flexible hoses for connecting tools) on the side wall of the container (and not in the mesh basket, as provided for in the closest analogue) simplifies maintenance of the device, since it is not required every time the basket is placed in the device

connect the nozzles to the fluid supply system, and eliminates the possibility of damage to the nozzles when loading medical instruments into the basket. The use of three traditional pumps (widely known designs) in the fluid supply system, each of which performs its own function assigned to it in the device, eliminates the need for a special powerful pump with valve control and thereby reduces the cost of the device as a whole, and also makes it possible maintain the device in working condition even if one of the operating pumps fails. The use in the proposed device of two separate (independently operating independently of one another) control panels, each of which is focused on ensuring the execution of a certain group of operations in the device, significantly reduces the possibility of erroneous inclusion of an unnecessary operation by maintenance personnel, and allows the medical staff to work in a more accessible algorithm .

The case and container with a lid are made of stainless steel, which, first of all, provides reliable protection against ultrasonic radiation, and, in addition, allows the use of effective disinfectants when caring for the device.

The hoses used in the device for fluid collection and discharge are located outside the housing from its lateral sides, which allows visual monitoring of their condition.

To simplify the transportation of the device, the case has built-in plastic handles.

The device uses two autonomous operating ultrasonic generators, each of which provides a corresponding group of ultrasonic emitters, which allows you to maintain the device in working condition when one of the generators fails.

The essence of the claimed utility model is illustrated by graphic material, where:

figure 1 shows a General view of the inventive device;

figure 2 - one of the control panels;

figure 4 is a schematic representation of the fundamental components of the device in their relationship.

The proposed device can be used in operating rooms, dressings, treatment rooms, in dentistry, gynecology, cosmetology and other departments of medical institutions where manipulations are carried out using medical instruments. Cleaning of medical instruments is carried out in aqueous solutions of detergents and disinfectants recommended for use with ultrasound by guidelines and recommendations of health authorities.

The device comprises a stainless steel liquid container 1 mounted in a stainless steel housing 2 having integrated plastic handles. Capacity 1 has a stainless steel lid 3. The housing 2 is made integral with smooth surfaces, on which there are no seals and fasteners with a capacity of 1, which eliminates the presence of inaccessible zones, creating inconvenience when washing and rubbing the housing 2 using a disinfectant liquid.

Inside the container 1 is inserted a metal mesh basket 4, which serves to accommodate the medical instrument to be cleaned.

Ultrasonic piezoelectric elements 5 are fixed outside the bottom of the tank 1. Two ultrasonic generators 6 and 7 are installed on the bottom of the body 2, each of which has its own group of ultrasonic emitters 8. The emitters convert ultrasonic frequency electricity supplied from the generator into mechanical vibrations of the bottom and walls of the bathtub and cavitation in a washing solution.

Outside the side of the tank 1 are located heating elements 9 that maintain the temperature in the detergent solution in the tank in accordance with the set values of the temperature controller.

On the side wall of the tank 1 mounted nozzles 10, which are designed to provide flushing cavities in medical instruments. The nozzles 10 are equipped with flexible hoses (not shown) through which the flushing fluid from the nozzles 10 enters the washable cavities (including channels) in the tools.

Three pumps are provided in the device: pump 11 is used for collecting water, pump 12 is for collecting solution into the tank, and pump 13 is used to circulate the washing liquid from the tank to the nozzles.

On the wall of the housing 2 there are two separate (stand-alone, working independently from each other) control panels, of which the panel 14 serves to control ultrasonic processing and temperature conditions, and the panel 15 - to control the operations for the collection of water and solution and control the hydrodynamic processing.

On the remote control 14 are located: the “Network” key 16 (controls the inclusion of the entire device in the power supply network or turning it off from the network), a digital processing time indicator 17, an ultrasonic emitter operation indicator 18, a heating element 9 operation indicator 19, a processing temperature digital indicator 20, button 21 to set the processing time "-", button 22 to set the processing time "+", button 23 to start / stop operation, button 24 to set the processing temperature "-", button 25 to set the processing temperature "+". The remote control 14 allows you to adjust the ultrasonic cleaning time with the indication of the set time, maintain the temperature of the liquid in the set parameters with the indication of the current temperature.

On the remote control 15 are located: a digital display 26 for displaying the concentration of the solution, a key 27 on / off the pump 13 for circulating the washing liquid, a fine-tuning button 28 (used to fine-tune the operation of the pumps), a concentration button “-”, a concentration selection button 30 “+”, Button 31 for starting the water / solution set mode, button 32 for stopping the water / solution set mode.

The liquid is drawn into the device through the nozzle 33, the concentrated solution is drawn through the nozzle 35, and the used solution is drained from the device through the drainage valve 34. The hoses for the collection and discharge of liquid are located outside the housing from its lateral sides (not shown).

Switching modes of fluid circulation is carried out on the remote control 15. Key 27 is used to turn on / off the pump 13, forcing the fluid from the tank to flow under pressure to the manifold 36 and from it to the nozzles

10. The circulation mode can be activated regardless of the ultrasonic treatment mode.

Connecting the device to the power network is carried out using a three-wire network cable, one of the wires of which is grounding.

The device is used as follows:

Pour water and concentrated solution through fittings 33 and 35 using pumps 11 and 12 into the tank 1 to the desired level. To set the water and the solution, select the necessary concentration with the buttons 29 and 30 on the remote control 15. After that, press button 31, the container 1 will automatically fill. In case of an emergency, the process of filling the container 1 can be stopped by pressing the button 32. After filling the container 1, you can select ultrasonic processing with the possibility of heating and maintaining the washing liquid at the right temperature. These functions are controlled by the remote control 14. Separate the contaminated tool into cavity and cavity. The incomplete tool intended for cleaning is placed in the basket 4, which is lowered into the container 1. The cavity tool is attached to the nozzles 10 using flexible hoses. The container 1 is closed with a lid 3. On the remote control 14, the processing time and the temperature of the solution are set: the ultrasonic processing time is set with buttons 21 and 22, and the desired liquid temperature is set with buttons 24 and 25. By pressing the button 23 start the ultrasonic processing. In this case, the current temperature is displayed on the digital indicator (display) 20, and the set processing time is displayed on the digital indicator (display) 17. By pressing the button 27 on the remote control 15, the circulation mode of the fluid collected in the tank 1 is turned on or off through nozzles 10 for flushing the cavity tool . Hydrodynamic treatment is carried out by supplying a washing solution from a container 1 under pressure using a pump 13 through nozzles 10 to the internal cavities of the processed tool. After cleaning, the cleaned tool is removed from the device, the used solution is drained through a drainage valve 34.

Cleaning cavity and non-cavity tools can be carried out simultaneously or separately.
