The invention relates to medical engineering, in particular to a device for cleaning and sterilization of endoscopes, and can be used in medical institutions using endoscopes in the process of diagnosis and/or treatment.

Currently in medical institutions acute value may not be disposable. Primarily these include endoscopes are widely used in the diagnosis and treatment. The problem is that, firstly, the endoscopes are complex instruments, structurally made of different materials, which imposes constraints on the choice of sterilizing agents, so as to avoid destruction of these materials, and, secondly, you need to handle in the Assembly as the outer and inner surfaces of endoscopes and accessory equipment.

A device for sterilization of endoscopes using sterilizing solutions containing frame with a bathtub and a hydraulic system, which feeds into the tub working solutions, with the bath with the possibility to perform oscillatory movements in the longitudinal direction by passing through the endoscope working solution [1].

However, the known device is complicated, energy and MATERIALICA, and additionally does not provide the desired degree of sterilization.

Known device that implements a multi-stage cleaning method using different chemicals and compounds for cleaning and disinfection of endoscopes, such as pogledati, supply of disinfectant fluid with subsequent purging of the channels of the endoscope and the neutralization of sterile water passing sterile filter [2], and the plant is equipped with control means that each stage of the program generates the appropriate signals, including acoustic or visual signals, the readings in the form of instructions or statements, in which we manually disinfection process.

The disadvantage is the complexity of its service, the use of chemicals, increased requirements for safety and require additional wastewater treatment.

Known device, in which during operation prepare solutions for the processing of the endoscope containing ozone contact column, the lower part of which is connected to the tank for cleaning and disinfection, and the preparation of disinfectant, namely ozonated water is carried out automatically [3] . However, the installation of complex and energy intensive, and is not achieving consistently high results.

The installation also contains a power supply and control unit, connecting the electrodes of the electrochemical cell with the poles of the power source, sensors and control equipment connected to the control unit [4]. This unit is selected as a prototype. During operation of the installation, use significantly less reagents, it is easier to automate.

A disadvantage of the known solutions is its relative complexity, the inability to ensure sterilization of the endoscope. In addition, in the known solution predusmotret must be subjected to the disinfecting solution processing, which leads to energy consumption and reduces the functionality of the installation. In addition, the prototype used a membrane electrochemical cell with planar electrodes and energizers, located at the electrode surface, which also increases the energy consumption of the process by increasing the electric and hydraulic resistance, as well as shielding the electrode surface. When serial processing in the anode, and then in a cathode chamber of the solutions have enhanced corrosion activity that leads to the destruction of the metal parts of the endoscope. A known device operates with a pre-prepared solutions that require the use of additional containers of significant amounts because of the large consumption washing and sterilizing solutions.

The technical result of the use of the invention is to simplify installation, enabling sterilization of the endoscope, as well as the opportunity to fully automate the installation, except the destruction of the endoscope in the process, reducing reagent consumption and energy consumption for the process of cleaning and sterilization.

This result is achieved by the fact that usatii of the endoscope, made in the form of a tray, in which the device for draining waste solutions made in the form of the overflow pipe, a device for supplying solution to the external surfaces of the endoscope is made in the form of electro-mechanical agitators are installed on the bottom of the tray opposite from the overflow pipe end, a device for supplying washing and sterilizing solutions to the internal surfaces of the endoscope is made in the form of adapter.

The proposed construction of the tray with overflow pipe and a stirrer simple in execution and maintenance, when immersing the endoscope in the tray can effectively clean the interior and exterior surfaces of the endoscope.

Significant is the order of connection of the electrode chambers in the course of the stream in the synthesis of washing and sterilizing solutions. Due to the sequential processing of cathode and anode chambers accumulate in solution substances, providing both the washing and sterilizing effect, which is not possible if a different sequence of passage of cells, as in a cathode chamber will collapse active complexes formed in the anode chamber.

In addition, it should be noted that when the sequence of passage of the cameras according to the invention of micro-bubbles electrolytic hydrogen generated in the cathode chamber, proceed with the solution in the anode, which allows you to use the Onna activity.

The flotation machine is equipped with a device for removal of treated water, made in the form of a vertical pipe installed along the axis of the flotation cell with the entrance in the lower part at its bottom. In the upper part of the flotation cell is installed fixture for removal of flotsam.

The form of execution of the flotation cell may be different, the important thing is that he has a cylindrical shape, providing the twisting of the flow of the treated water in the flotation cell at its tangential entry. The flotation machine can be made cylindrical with a constant cross-section throughout its length, or cylindrical with a conical bottom, or cone-shaped and is mounted toward the top.

The location of the tangential input is determined depending on the shape and performance of the flotation cell.

Supplied with the necessary quantity occidentalizes reagent in the solution is carried out using easily automated tools that allows you to securely maintain the concentration in the solution netearth sodium, that allows to reduce the corrosivity of the fluids and to provide the most complete wetting of all surfaces of the endoscope solutions and to assure removal of harmful and polluting substances and supply of active complexes for disinfection and sterilization processing surfaces.

For the preparation of washing and sterilizing solutions and for purification of water from heavy metal ions and hardness salts using the same electrochemical cell is a vertical, cylindrical coaxial electrodes and coaxial ceramic diaphragm dividing the interelectrode distance on the cathode and anode chambers with the inlet at the bottom and top parts, which ensures the stability of the resulting characteristics of washing and sterilizing solutions at minimum cost of electricity, as well as to achieve the required efficiency in minimal time.
