[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0049] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0052] For cleaning and disinfecting the lumen of an endoscope, existing technology provides a cleaning and disinfection connection device. First, the endoscope is placed in a tray, and then the tray is installed in the cleaning chamber of the cleaning and disinfection equipment. Multiple cleaning connectors and leak detection connectors are provided on the side wall of the cleaning chamber. Then, flexible hoses are used to connect the cleaning connectors and leak detection connectors on the cleaning chamber to the corresponding interfaces on the endoscope. This connects the leak detection channel of the endoscope with the leak detection system of the cleaning and disinfection equipment, and connects the cleaning channel of the endoscope with the cleaning and disinfection system of the cleaning and disinfection equipment, so as to perform leak detection and cleaning and disinfection of the lumen of the endoscope.

[0053] However, the problem with this solution is that the cleaning chamber has multiple trays, and the upper and lower layers of the trays have rotating spray arms. The endoscopes need to be connected inside the cleaning chamber after the trays are installed. It is very inconvenient to operate and connect the various interfaces of the endoscopes, and it is easy to bump the arms. After cleaning and disinfection, all the connecting hoses must be disconnected inside the cleaning chamber, the trays must be removed, the endoscopes must be taken out of the trays and placed on the drying table. The endoscopes are then dried with an air gun, and then the storage trays are replaced to transfer the endoscopes to the endoscope storage equipment. This process is extremely cumbersome.

[0054] To address the aforementioned issues, this embodiment provides cleaning and disinfection equipment and a method for cleaning and disinfecting medical devices, thereby solving the problems of inconvenient operation and cumbersome steps in the existing technology for leak detection, cleaning, disinfection and drying processes of endoscopes. It can be applied to the technical field of medical disinfection equipment.

[0055] Reference Figure 1The cleaning and disinfection equipment is used to clean endoscopes loaded in a basket 100, and specifically includes a cleaning chamber 1, a water inlet system 2, a consumables addition system 3, and a circulating cleaning system 4. The cleaning chamber 1 has a cleaning cavity 11 for holding the basket 100, and a circulating outlet 12 and a circulating inlet 13 connected to the cleaning cavity 11. The water inlet system 2 is used to add water to the cleaning cavity 11, either through the circulating inlet 13 or directly through a dedicated water inlet interface. The consumables addition system 3 is used to add cleaning and disinfection media to the cleaning cavity 11. The cleaning and disinfection media serve cleaning and disinfection functions, respectively. The cleaning media includes enzyme solutions, and the disinfection media includes various medical disinfectants. The consumables addition system 3 can add cleaning and disinfection media through the circulating inlet 13 or directly through a dedicated reagent addition interface. The circulating cleaning system 4 includes a circulating pump 41. The input end of the circulating pump 41 is connected to the circulating outlet 12 via a pipeline, and the output end of the circulating pump 41 is connected to the circulating inlet 13 via a pipeline. By setting up the circulating outlet 12 and the circulating inlet 13, and by using the circulating pump 41 of the circulating cleaning system 4 to drive the liquid out of the cleaning chamber 11 from the circulating outlet 12, and then back through the circulating inlet 13, the cleaning and disinfection media and water are recycled, reducing consumption.

[0056] Continue to refer to Figure 1 For cleaning and disinfecting the outer wall of the endoscope, the cleaning and disinfection equipment also includes a spray device 5. The spray device 5 is set in the cleaning chamber 11. The spray device 5 has a spray chamber 51 and includes a nozzle. The spray chamber 51 is connected to the circulating liquid inlet 13. The nozzle is used to spray the liquid located in the spray chamber 51 into the cleaning chamber 11 to clean the outer wall of the endoscope by spraying.

[0057] In traditional cleaning and disinfection equipment, drying endoscopes typically involves removing the endoscope, blowing hot air into its interior using a hot air blower, and wiping away water from its outer surface. However, this drying process is complex and often ineffective. (Continue to refer to...) Figure 1To address the aforementioned issues, the cleaning and disinfection equipment in this embodiment further includes a hot air drying system 7. The hot air drying system 7 is used to blow air into the circulating inlet 13, thereby allowing the endoscope to be dried after cleaning and disinfection operations. Specifically, the hot air drying system 7 includes an air filter 71, a fan 72, and an electric heating box 73 connected sequentially via pipelines. The air filter 71 is directly connected to the air and used to filter the incoming air. The fan 72 drives the air into the pipeline. The electric heating box 73 is equipped with a third heating device 74 for heating the air. The output end of the electric heating box 73 is connected to the circulating inlet 13, specifically connected to the circulating cleaning system 4, and then connected to the circulating inlet 13 via the circulating cleaning system 4. Optionally, a one-way valve 75 is provided at the output end of the electric heating box 73 to prevent backflow of air in the cleaning chamber 11. Optionally, a third temperature sensor 76 is provided at the output end of the electric heating box 73 to detect the air temperature in the pipeline.

[0058] Continue to refer to Figure 1 For cleaning and disinfecting the endoscope lumen, the basket 100 has an internal cleaning chamber that communicates with the endoscope lumen. The cleaning chamber 1 has multiple circulating inlets 13, some of which communicate with the spray chamber 51, while others communicate with the internal cleaning chamber via pipes. In other words, the liquid entering the circulating cleaning system 4 is used to clean the outer wall of the endoscope via the spray chamber 51, and another portion communicates with the internal cleaning chamber via pipes to reach the endoscope lumen, thus achieving cleaning and disinfection of the endoscope lumen. To ensure cleaning effectiveness, a flow sensor 42 is installed in this embodiment to detect the fluid flow rate in the pipes connected to the internal cleaning chamber, thereby determining whether the endoscope lumen is blocked and whether the cleaning fluid flow rate is too high or too low.

[0059] Continue to refer to Figure 1 In this embodiment, the cleaning chamber 11 contains multiple baskets 100, which are spaced vertically. Above and below each basket 100, multiple nozzles are arranged horizontally to increase the spray area and enhance the cleaning effect. Specifically, multiple spray devices 5 are provided, and the spray chambers 51 of each spray device 5 are connected to the circulating liquid inlet 13. Furthermore, the uppermost spray device 5 has one row of nozzles that spray liquid downwards, the lowermost spray device 5 has one row of nozzles that spray liquid upwards, and the middle spray device 5 has two rows of nozzles, one row spraying liquid downwards and the other row spraying liquid upwards.

[0060] Continue to refer to Figure 1The catalytic effect of cleaning media such as enzyme solutions generally requires a specific temperature. In order to make the water in the cleaning chamber 11 reach this temperature, the cleaning and disinfection equipment also includes a first heating device 14 installed in the cleaning chamber 11. The first heating device 14 is used to heat the liquid in the cleaning chamber 11. Optionally, a first temperature sensor 111 is also installed on the wall of the cleaning chamber 11. The first temperature sensor 111 is used to detect the temperature of the fluid in the cleaning chamber 11.

[0061] Continue to refer to Figure 1 The water inlet system 2 includes a room temperature water tank 21 and a heated water tank 22 for storing water. The heated water tank 22 is equipped with a second heating device 221 for heating the water stored in the heated water tank 22. Both the room temperature water tank 21 and the heated water tank 22 are connected to the cleaning chamber 11. The room temperature water tank 21 stores water at room temperature. After room temperature water is introduced into the heated water tank 22, it is heated by the second heating device 221, thereby adding water from the heated water tank 22 to the cleaning chamber 11, so that the water in the cleaning chamber 11 quickly reaches the suitable temperature for the catalytic action of the cleaning medium such as enzyme solution. Optionally, the heated water tank 22 is equipped with a second temperature sensor 222 to detect the temperature of the water in the heated water tank 22.

[0062] Continue to refer to Figure 1 In some embodiments, when the ambient temperature water tank 21 cannot meet the supply of ambient temperature water to the cleaning chamber 11, the following structure can be used to assist in water supply: the water inlet system 2 also includes a water filling device for connecting to the water supply network. The water filling device is used to add water to the cleaning chamber 11, and the water filling device is specifically a water filling pipeline 23. Optionally, the water filling pipeline 23, the ambient temperature water tank 21, and the heated water tank 22 all have a water supply network connection end 24 to connect to the water supply network. Optionally, the water filling pipeline 23 is provided with a first control valve 25 to facilitate the control of the opening and closing of the water filling pipeline 23. In addition, the outlet ends of the ambient temperature water tank 21 and the heated water tank 22 are also provided with first control valves 25 to control the water flow from the ambient temperature water tank 21 and the heated water tank 22 into the cleaning chamber 11. The temperature of the water added to the cleaning chamber 11 by the water inlet system 2 can be controlled by changing the opening degree of the above three first control valves 25.

[0063] Continue to refer to Figure 1The consumables adding system 3 includes a consumables storage container 31 for storing cleaning or disinfecting media, and the consumables storage container 31 is connected to the cleaning chamber 11. Multiple consumables storage containers 31 are provided; some are used to store cleaning media, while others are used to store disinfecting media and alcohol. Specifically, the consumables storage containers 31 can be directly connected via a separate interface, or they can be connected to a circulation inlet 13, which in turn connects to the cleaning chamber 11. Optionally, the consumables adding system 3 also includes a first peristaltic pump 32. The input end of the first peristaltic pump 32 is connected to the consumables storage container 31, and the output end is connected to the circulation inlet 13 or directly to the cleaning chamber 11, and is used to add the cleaning or disinfecting media from the consumables storage container 31 to the cleaning chamber 11.

[0064] Continue to refer to Figure 1 The basket 100 has a leak detection chamber that can communicate with the endoscope cavity. The cleaning and disinfection equipment also includes a leak detection system 6, which is used to deliver a leak detection medium to the leak detection chamber. Specifically, the leak detection system 6 includes a leak detection pipeline 61. One end of the leak detection pipeline 61 is used to introduce a leak detection medium, typically compressed gas, and the other end is used to communicate with the leak detection chamber. This allows the leak detection medium, typically gas, to be introduced into the endoscope cavity. Leakage detection of the endoscope can be performed by detecting the gas pressure in the endoscope cavity. Specifically, a pressure sensor 62 can be installed on the leak detection pipeline 61 to detect the gas pressure. Optionally, a second control valve 63 is installed on the leak detection pipeline 61 to control the opening and closing of the leak detection pipeline 61, thereby controlling the start and end of the leak detection step and preventing the leak detection pipeline 61 from affecting the cleaning and disinfection process during other cleaning and disinfection procedures.

[0065] Continue to refer to Figure 1 The cleaning and disinfection equipment also includes a drainage system 8, which is used to drain the liquid in the cleaning chamber 11. Specifically, the drainage system 8 includes a drainage pump 81, the input end of which is connected to the circulation outlet 12, or to other drainage interfaces provided on the wall of the cleaning chamber 11, and the output end of the drainage pump 81 is connected to the downstream sewage treatment system.

[0066] Continue to refer to Figure 1The cleaning and disinfection equipment also includes an alcohol drying system 9, which is used to blow gaseous alcohol into the circulation inlet 13. Specifically, the alcohol drying system 9 includes an alcohol storage tank 91 and a second peristaltic pump 92. The input end of the second peristaltic pump 92 is connected to the alcohol storage tank 91, and the output end is connected to the circulation inlet 13. In addition, an atomizing device is provided between the output end of the second peristaltic pump 92 and the circulation inlet 13 to atomize the alcohol. By introducing gaseous alcohol into the circulation inlet 13, the surface of the endoscope and the endoscope cavity can be dried quickly.

[0067] Continue to refer to Figure 1 The cleaning and disinfection equipment also includes an exhaust pipe 15 for discharging gas from the cleaning chamber 11. Optionally, the exhaust pipe 15 is equipped with a one-way valve to prevent outside air from entering the cleaning chamber 11 through the one-way valve.

[0068] This embodiment also provides a method for cleaning and disinfecting medical devices, implemented using the aforementioned cleaning and disinfection equipment, with reference to... Figure 2 The cleaning and disinfection methods for medical devices include the following steps:

[0069] S10: Determine if the endoscope is damaged and leaking air; determining if the endoscope is damaged and leaking air includes: delivering a leak detection medium, which is gas, to the leak detection chamber through the leak detection system 6; determining if the gas pressure in the endoscope chamber is not lower than the set pressure; if the gas pressure in the endoscope chamber is not lower than the set pressure, then the endoscope is determined not to be damaged and leaking air, and step S100 is executed; if the gas pressure in the endoscope chamber is lower than the set pressure, then the endoscope is determined to be damaged and leaking air.

[0070] This is the leak detection phase. The set pressure is the minimum gas pressure in the endoscope cavity that, after the leak detection medium is delivered into the cavity, will not cause any damage or leakage. The leak detection system 6 delivers the leak detection medium (usually air) into the cavity. The gas pressure in the cavity is then measured. If the pressure is not lower than the set pressure, it indicates that the endoscope is not damaged or leaking, and the reading can be recorded before proceeding with subsequent cleaning and disinfection. If the pressure is lower than the set pressure, it indicates that the endoscope is damaged and leaking. In this case, the reading should be recorded or an alarm should be triggered to alert the operator that the endoscope needs repair. In this situation, subsequent cleaning and disinfection procedures are usually not performed.

[0071] S100: Rinse the endoscope; Rinse the endoscope includes: controlling the water inlet system 2 to add water into the cleaning chamber 11; controlling the circulating cleaning system 4 to rinse the endoscope and drain the water from the cleaning chamber 11.

[0072] This is the rinsing stage. Room temperature water can be used in this step. Specifically, the first control valve 25 is opened to control the room temperature water tank 21 and the water supply pipe 23 to inject water into the cleaning chamber 11. Then, the endoscope is rinsed by controlling the circulating cleaning system 4. Specifically, the circulating pump 41 is turned on to circulate the water in the cleaning chamber 11, completing the rinsing. After rinsing, the water in the cleaning chamber 11 is drained through the drainage system 8.

[0073] S200: Clean the endoscope; cleaning the endoscope includes: controlling the water inlet system 2 to add water into the cleaning chamber 11, and controlling the consumables addition system 3 to add cleaning medium into the cleaning chamber 11; controlling the circulation cleaning system 4 to clean the endoscope and discharge the cleaning medium in the cleaning chamber 11.

[0074] This is the cleaning stage. A cleaning medium is typically used in this step; in this embodiment, the cleaning medium is an enzyme solution. Therefore, a certain amount of hot water needs to be added to maintain the mixture of water and enzyme solution in the cleaning chamber 11 at a suitable temperature. Specifically, the first peristaltic pump 32 is controlled to add the enzyme solution from the consumable storage tank 31 to the cleaning chamber 11. Simultaneously, the opening degree of the three first control valves 25 is controlled, or some of the first control valves 25 are opened or closed, to control the temperature of the added water. This temperature is detected by the first temperature sensor 111. If the temperature is low, the first heating device 14 is activated to directly heat the mixture in the cleaning chamber 11. The circulating cleaning system 4 is controlled to clean the endoscope. After cleaning, the cleaning medium in the cleaning chamber 11 is discharged through the drainage system 8.

[0075] S300: Rinse the endoscope; Rinse the endoscope by: controlling the water inlet system 2 to add water into the cleaning chamber 11; controlling the circulating cleaning system 4 to rinse the endoscope and drain the rinsing water from the cleaning chamber 11.

[0076] This is the rinsing stage. In this step, either room temperature or hot water can be used. Specifically, the first control valve 25 is opened to control the room temperature water tank 21 and the water supply pipe 23 to fill the cleaning chamber 11 with water. A certain amount of hot water can also be added to the heating water tank 22. The circulating cleaning system 4 is controlled to rinse the endoscope. After rinsing, the rinsing water in the cleaning chamber 11 is drained through the drainage system 8. This step can be repeated 2-3 times for thorough rinsing.

[0077] S400: Disinfect the endoscope; Disinfecting the endoscope includes: controlling the water inlet system 2 to add water into the cleaning chamber 11, and controlling the consumables addition system 3 to add disinfectant medium into the cleaning chamber 11; controlling the circulating cleaning system 4 to disinfect the endoscope and discharge the disinfectant medium from the cleaning chamber 11.

[0078] This is the disinfection stage. In this step, either room temperature water or hot water can be used. Specifically, the first control valve 25 is opened to control the room temperature water tank 21 and the water supply pipe 23 to fill the cleaning chamber 11 with water. A certain amount of hot water can also be added to the heating water tank 22. In addition, the first peristaltic pump 32 is controlled to add the disinfection medium from the consumable storage container 31 to the cleaning chamber 11. The circulating cleaning system 4 is controlled to disinfect the endoscope. After disinfection, the disinfection medium in the cleaning chamber 11 is discharged through the drainage system 8.

[0079] S500: Drying the endoscope; Drying the endoscope includes: controlling the hot air drying system 7 to blow air into the circulating inlet 13; controlling the alcohol drying system 9 to blow gaseous alcohol into the circulating inlet.

[0080] This refers to the drying stage. Traditional drying methods involve removing the endoscope and placing it in an oven, a cumbersome process that inevitably leads to contamination due to manual handling. Therefore, in this embodiment, after cleaning and disinfecting the endoscope, drying continues. Specifically, fan 72 starts operating, blowing air into the circulating liquid inlet 13, and determining whether to activate the third heating device 74 to heat the air based on its actual temperature. During drying, excess air is discharged from the exhaust pipe 15. By setting up a hot air drying system 7 to dry the endoscope, the traditional endoscope drying process is simplified, while allowing the endoscope to be stored in the basket 100 for a longer period.

[0081] Simultaneously, the endoscope is dried by the alcohol drying system 9. Specifically, an atomizing device can be installed in the pipeline connecting the alcohol storage tank 91 and the circulation inlet 13 to atomize the alcohol. The second peristaltic pump 92 of the alcohol drying system 9 delivers gaseous alcohol to the circulation inlet 13, so that the mixed gas of air introduced by the hot air drying system 7 and alcohol introduced by the alcohol drying system 9 simultaneously dries the outer wall and the endoscope cavity of the endoscope.
