Description

Technical Field

[0001] This utility model relates to the field of disinfection machine technology, and more specifically, to a pressurized circulation device for a pressure steam cleaning and disinfection machine. Background Technology

[0002] With the rapid development of medical technology, surgical instruments are becoming increasingly diverse, with more complex functions and structures. Reusable surgical instruments must be thoroughly cleaned and dried before packaging and sterilization. Cleaning the surfaces, joints, teeth, and crevices of precision and complex surgical instruments is particularly challenging. Surgical instruments often retain non-water-soluble contaminants such as blood, bodily fluids, secretions, and human tissue after surgery, containing a large number of microorganisms. If not thoroughly cleaned over a long period, biofilms can easily form, preventing the penetration of sterilization media or hindering effective contact between microorganisms and steam, severely affecting sterilization effectiveness and increasing the risk of infection for patients upon reuse. Simultaneously, residual blood, bodily fluids, and other contaminants on the surface of surgical instruments can corrode and damage them. Once a biofilm forms, even with proper and effective sterilization, pathogenic microorganisms can still survive. Studies have indicated that 50% of hospital-acquired infections are related to biofilms on medical instruments. Therefore, effective sterilization of surgical instruments is a key factor in preventing surgical site infections and an important measure for controlling hospital-acquired infections. Proper and high-quality cleaning, disinfection, and drying of surgical instruments are crucial steps and prerequisites for successful sterilization.

[0003] A cleaning and disinfection machine is essentially a device that uses cleaning and disinfecting agents in an automated controlled program to complete the initial washing, cleaning, rinsing, disinfection, and final rinsing of instruments, replacing traditional manual cleaning and disinfection methods. It immerses the instruments in the cleaning or disinfecting solution for thorough cleaning and disinfection. However, it requires injecting large amounts of cleaning and disinfecting agents into the cleaning tank, resulting in a significant water consumption. Therefore, how to achieve thorough cleaning of instruments using only a small amount of water and cleaning agent is the technical problem this invention aims to solve. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0025] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0026] like Figures 1-4As shown, this utility model provides a pressurized circulation device for a pressure steam cleaning and disinfection machine, including: a water supply system connected to a water tank, the water supply system being used to continuously supply water to the water tank; a pressurizing device and a circulating spray device; the pressurizing device being installed in the water tank, used to pressurize and transport the water in the water tank to the circulating spray device; the circulating spray device being installed in the cleaning pool of the disinfection machine; the pressurizing device being connected to the circulating spray device, used to spray water at high pressure onto the equipment; the water supply system, pressurizing system, and spray system are all program-controlled by the control module of the disinfection machine, thereby monitoring the water level in the water tank and monitoring and controlling the rinsing intensity; by setting up the pressurizing device and the circulating spray device, a good cleaning effect can be achieved with only a small amount of water.

[0027] Furthermore, it also includes a cleaning fluid supply system, which is connected to the water tank and the circulating spray device via solenoid valves, allowing the cleaning fluid supply system to supply cleaning fluid to either the water tank or the circulating spray device. When the cleaning fluid needs to be used directly to clean the equipment, the solenoid valve between the cleaning fluid supply system and the circulating spray device opens, allowing the cleaning fluid to be sprayed directly through the circulating spray device; when the cleaning fluid needs to be mixed with water before use, the solenoid valve between the cleaning fluid supply system and the water tank opens, allowing the cleaning fluid to enter the water tank, mix with water in a specific ratio, and then be pressurized and delivered to the circulating spray device.

[0028] Furthermore, the pressurizing device consists of a water pump and a heating system. The water pump is connected to the heating system, and the heating system is connected to the circulating spray device via a solenoid valve, such as... Figure 1 As shown, both the water pump and the heating system are typically located inside the water tank. The water pump draws liquid (water or water mixed with cleaning solution) from the tank, pressurizing and transporting the liquid. The heating system heats the water into steam or heats the water mixed with cleaning solution. To fully utilize the heating system, it is usually located inside the water tank, or on the outer wall or bottom of the tank, maintaining contact with it, so that the liquid inside the tank can be preheated by the heating system.

[0029] Furthermore, the circulating spray device comprises a fixed spray element 1 installed on the inner wall of the cleaning tank, a movable spray element 2 installed at the bottom of the cleaning tank, and a rotating spray element 3 installed on the top cover of the cleaning tank. The fixed spray element 1 is located on the inner wall of the cleaning tank and cleans the instruments from all sides. The movable spray element 2 is located at the bottom of the cleaning tank and can reciprocate along the bottom of the cleaning tank. Figure 2As shown by the middle arrow, the bottom of the instrument is cleaned. Because liquid on the instrument will slide to the bottom under gravity, contaminants easily remain there. Therefore, a moving spray unit 2 is needed for reciprocating rinsing. A rotating spray unit 3 is located on the top cover of the cleaning tank and can rotate. Figure 2 As shown, the cleaning tank is equipped with a shelf for placing instruments. The bottom of the cleaning tank is connected to the recovery system to recover the liquid after cleaning, preventing the liquid from accumulating in the cleaning tank and soaking the instruments.

[0030] The working principle and beneficial effects of the above technical solution: Through the design of the above structure, the pressurizing equipment can control the water inflow, spray pressure and temperature. Under the control of the disinfectant control module, the circulating spray device can realize the dynamic cleaning of instruments. It has the advantages of low friction loss, large suction range, large water flow and pressure balance. It can achieve good cleaning effect with a small amount of water and cleaning reagent.

[0031] To facilitate dynamic cleaning with the mobile spray unit 2 and further improve cleaning efficiency, several detachable slit spray units can be installed on the mobile spray unit 2. The slit spray units are U-shaped, and the instruments are placed inside the U-shape during cleaning. The bottom of the slit spray units is connected to the mobile spray unit 2. Pressurized liquid (water or water mixed with cleaning solution) can be delivered from the mobile spray unit 2 to the slit spray units, thereby providing close-range high-pressure and high-temperature rinsing of the instruments from head to tail during the movement.

[0032] The slit spray device consists of a guide 5 with a first channel 4 and a connecting post 6. The first channel 4 is located inside the guide 5. The guide 5 is U-shaped, and two opposite inner sidewalls of the guide 5 are provided with first holes 7 communicating with the first channel 4. Pressurized liquid can reach the first holes 7 from the first channel 4 and be sprayed onto the instrument surface through the first holes 7. There are four first holes 7, symmetrically arranged on two opposite inner sidewalls of the guide 5. Figure 3 and Figure 4As shown, this allows the gap spray component to be used with wider and thicker instruments. The bottom of the guide 5 is provided with a mounting groove 8, and the top of the connecting post 6 is connected to the inner top surface of the mounting groove 8. The inner top surface of the mounting groove 8 is provided with several second holes 9 communicating with the first channel 4. The movable spray component 2 is provided with a plug adapted to the mounting groove 8. When the gap spray component is not installed, pressurized liquid can be sprayed from the through hole of the plug of the movable spray component 2; after the gap spray component is installed, the plug of the movable spray component 2 is inserted into the mounting groove 8, and the through hole of the plug communicates with the second holes 9, thereby allowing high-pressure liquid to be transported from the movable spray component 2 to the first channel 4. The mounting groove 8 is provided with an annular groove, and both the connecting post 6 and the second holes 9 are located within the annular groove. A sealing ring 12 is provided within the annular groove, such as... Figure 4 As shown, this prevents high-pressure liquid from overflowing after the plug of the movable spray unit 2 is connected to the mounting slot 8.

[0033] Because the high-pressure liquid is diverted after entering the first channel 4, the pressure of the liquid ejected from the first hole 7 decreases, affecting the flushing effect. To eliminate the pressure impact caused by the diversion, we further optimized the guide 5. In this embodiment, the guide 5 has opening slots on both outer side walls. The first hole 7 and the first channel 4 are connected to the opening slots. A cover plate 10 is provided at the opening of the opening slot. A distance is left between the inner side wall of the cover plate 10 and the side wall of the opening slot where the first hole 7 is located. This distance forms a second channel 11, and the first hole 7 and the first channel 4 are connected to the second channel 11. The inner side wall of the cover plate 10 is inclined. The distance D from the inner side wall (bottom) of the cover plate 10 to the point where the opening slot connects to the first channel 4 is greater than the distance d from the inner side wall (top) of the cover plate 10 to the point where the opening slot connects to the uppermost first hole 7. Figure 4 As shown, the design of the cover plate 10 causes the opening area of ​​the second channel 11 to gradually decrease from the first channel 4 towards the first hole 7. As the cross-section of the second channel 11 gradually decreases, the water pressure reduced due to diversion can gradually increase, thereby compensating for the reduced water pressure caused by diversion. At the same time, the structural design of the opening groove and the cover plate 10 simplifies the processing of the guide 5, making it easier to manufacture the first channel 4 and the first hole 7. Furthermore, the guide 5 and the cover plate 10 can be manufactured separately and assembled during use. The split design also allows the channel area of ​​the second channel 11 to be adjusted manually, simply by replacing the cover plate 10 with one of different thicknesses.
