Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device cleaning technology, and relates to a cleaning and disinfection device, particularly a fully automatic medical device cleaning and disinfection device and cleaning method. Background Technology
[0002] As we all know, some medical devices need to be inserted into the human body, such as endoscopes. Endoscopes can enter the stomach through the mouth or other natural orifices. Endoscopes can be used to see lesions that cannot be seen under X-rays. In order to meet the standards of medical use and avoid cross-infection, the endoscope must be cleaned and disinfected after each medical examination.
[0003] Patent application CN01217581.1 discloses a medical device cleaning and disinfection machine, including a cleaning and disinfection chamber and a medical device cleaning cart disposed within the chamber for placing medical devices. Cleaning medium spray arms are respectively installed at the top and bottom of the cleaning and disinfection chamber. A liquid supply connector for supplying cleaning medium to the spray arms in the medical device cleaning cart is also provided within the cleaning and disinfection chamber. The liquid supply connector is connected to the spray arms via a bayonet connector on the medical device cleaning cart. The cleaning and disinfection chamber also includes a dosing device for adding cleaning solution to the cleaning medium, consisting of a dosing pump and a dosing bottle. It can efficiently remove bacteria and clean dirt and bloodstains from the surface of medical devices.
[0004] However, existing cleaning and disinfection machines have the following problems.
[0005] Firstly, in existing cleaning and disinfection machines, when storing and retrieving medical devices, the door is opened in the forward direction, the medical devices to be cleaned are placed on the cleaning cart, and then the door is closed. Since the medical devices are in a "water environment" during cleaning and disinfection, a strict sealing effect is required. However, the open method in existing technology is prone to water leakage. Moreover, in order to ensure the sealing effect, a sealing strip needs to be installed on the door. However, the cleaning water or medicine will remain in the sealing strip, affecting the subsequent cleaning effect or corroding the sealing strip.
[0006] Secondly, since the cleaning and disinfection machine opens outwards, sufficient space is required for its use, which is not suitable for use in areas with limited space.
[0007] Third, existing cleaning carts have multiple partitions for placing medical devices. When medical devices are placed in baskets on the lower partition, medical staff need to bend over or squat to place them, which is inconvenient. If medical staff can stand and use all the baskets on the cleaning cart, the horizontal height of the lowest basket is required, which will increase the size of the entire cleaning and disinfection machine and increase production costs. Summary of the Invention
[0008] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fully automated medical device cleaning and disinfection device that features a well-sealed cleaning space, is compact in size, and can be used in a small area.
[0009] The objective of this invention can be achieved through the following technical solution: A fully automatic medical device cleaning and disinfection device, comprising:
[0010] The cabinet has a supporting plane, and a washing chamber is formed by recessing along the supporting plane, with the opening of the washing chamber pointing vertically upward.
[0011] The lifting assembly is installed inside the cabinet, and the output end of the lifting assembly can move up and down along the opening direction of the washing chamber. The output end of the lifting assembly can penetrate the support plane.
[0012] The door cover is connected to the output end of the lifting assembly. The lifting assembly drives the door cover to move along the opening direction of the washing chamber to open or close the washing chamber opening. A bracket is provided on the side of the door cover facing the washing chamber, and a work position for placing medical devices is provided on the bracket. When the door cover closes the washing chamber opening, the bracket is located inside the washing chamber; when the washing chamber opening is fully open, the bracket is located outside the washing chamber.

[0014] The disinfectant container is used to store disinfectant solution and the enzyme container is used to store enzyme solution. The disinfectant container is provided with a first outlet, which is connected to a first inlet through a pipeline to form an inlet channel for disinfectant solution. The enzyme container is provided with a second outlet, which is connected to a second inlet to form an inlet channel for enzyme solution.
[0015] The door cover or the wall of the washing chamber is equipped with a nozzle for inputting washing water. The nozzle is connected to the water inlet through a pipe to form a water inlet channel for clean water.
[0016] In the aforementioned fully automated medical device cleaning and disinfection equipment, the disinfectant container is also equipped with a return port, which is connected to the third port of the tee via a pipeline to form a return channel for the disinfectant.
[0017] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the support includes a first support, and the two sides of the open end of the first support are connected to the door cover; a second support with multiple workstations is provided, and the second support is connected to the closed end of the first support, wherein there are gaps between the two sides of the second support and the corresponding sides of the open end of the first support.
[0018] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the nozzles include multiple atomizing nozzles disposed on the wall of the washing chamber and a rotating nozzle disposed on the door cover. The multiple atomizing nozzles are evenly distributed on the wall of the washing chamber, and the spray direction of the multiple atomizing nozzles is towards the middle of the washing chamber. The rotating nozzle is disposed on the side of the door cover facing the washing chamber and located above the washing chamber.
[0019] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the door cover is also equipped with an air inlet, an air outlet, and an exhaust outlet. The air inlet and exhaust outlet are exposed on the surface of the door cover, and the air outlet is located on the same side as the support. A drying component is also installed inside the door cover. The drying component heats the air entering the air inlet and then blows it into the washing chamber through the air outlet.
[0020] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the drying component includes a heating element for heating the air; a driving element, the output end of which is connected to louvers installed at the air outlet. When the medical device and tray are being cleaned, the louvers are closed by the driving element; when the drying process is being performed, the louvers are opened by the driving element.
[0021] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the cabinet is also equipped with multiple water pumps and multiple solenoid valves. The multiple water pumps and multiple solenoid valves are located below the washing chamber. The water pumps are used to process the intake of clean water, disinfectant, and enzyme solution. The solenoid valves control the connection or blockage of the drain channel, disinfectant inlet channel, disinfectant return channel, enzyme inlet channel, and water inlet channel. The multiple water pumps include a first water inlet pump for the rotary nozzle, a second water inlet pump for the atomizing nozzle, a first water inlet pump for the disinfectant, and a second water inlet pump for the enzyme. The multiple solenoid valves include a water inlet solenoid valve for controlling the opening and closing of the water inlet channel, a circulation solenoid valve for controlling the opening and closing of the circulation channel, a first water inlet solenoid valve for controlling the opening and closing of the disinfectant inlet channel, a return solenoid valve for controlling the opening and closing of the disinfectant return channel, a second water inlet solenoid valve for controlling the opening and closing of the enzyme inlet channel, and a drain solenoid valve for controlling the opening and closing of the drain channel.
[0022] In the aforementioned fully automated medical device cleaning and disinfection equipment, a detection port is led out from the disinfectant container, and a dispensing pump is installed between the detection port and the disinfectant container.

[0023] In the aforementioned fully automatic medical device cleaning and disinfection equipment, the cabinet is also equipped with a control panel and a foot switch, and the foot switch is electrically connected to the control panel.
[0024] This invention also provides a cleaning method for a fully automated medical device cleaning and disinfection device, comprising the following steps using the aforementioned fully automated medical device cleaning and disinfection device:
[0025] S1: Place the medical instruments and trays to be cleaned on the rack;
[0026] S2, the lifting assembly drives the bracket to descend and enter the washing chamber, while the door cover is closed, so that the washing chamber forms a sealed space;
[0027] S3: Open the first water inlet pump, the second water inlet pump, and the water inlet solenoid valve, so that water flows through the pipeline into the rotating nozzle and the atomizing nozzle respectively to rinse the medical instruments and trays on the support. When the preset cleaning time is reached, open the drain solenoid valve to let the sewage in the washing chamber enter the drain channel through the drain port. Then close the first water inlet pump, the second water inlet pump, the water inlet solenoid valve, and the drain solenoid valve to achieve the first clean water spray.
[0028] S4: Open the second inlet pump and the second inlet solenoid valve to input the enzyme solution from the enzyme container into the washing chamber. After the preset inlet time is reached, close the second inlet pump and the second inlet solenoid valve, and open the first water inlet pump, the second water inlet pump, and the circulation solenoid valve to mix the water with the enzyme solution. The water mixed with the enzyme solution circulates between the first water inlet pump, the second water inlet pump, the rotary nozzle, the atomizing nozzle, the washing chamber, and the circulation solenoid valve. After the preset circulation spray is reached, generally 3 minutes, close the first water inlet pump, the second water inlet pump, and the circulation solenoid valve, and open the drain solenoid valve to let the wastewater mixed with the enzyme solution in the washing chamber enter the drain channel through the drain port, thus realizing enzyme solution spraying.
[0029] S5: Open the first water inlet pump, the second water inlet pump, and the water inlet solenoid valve, so that water flows through the pipeline into the rotating nozzle and the atomizing nozzle respectively to rinse the medical instruments and trays on the support. When the preset cleaning time is reached, open the drain solenoid valve to let the sewage in the washing chamber enter the drain channel through the drain port. Then close the first water inlet pump, the second water inlet pump, the water inlet solenoid valve, and the drain solenoid valve to achieve a second clean water spray.
[0030] S6: Open the first inlet pump and the first inlet solenoid valve to input the disinfectant from the disinfectant container into the washing chamber. After the preset inlet time is reached, close the first inlet pump and the first inlet solenoid valve, and open the first water inlet pump, the second water inlet pump, and the circulation solenoid valve to mix the water with the disinfectant. The water mixed with the disinfectant circulates between the first water inlet pump, the second water inlet pump, the rotating nozzle, the atomizing nozzle, the washing chamber, and the circulation solenoid valve. After the preset circulation spray is reached, close the first water inlet pump, the second water inlet pump, and the circulation solenoid valve, and open the return solenoid valve to let the disinfectant flow back to the disinfectant container through the return channel and the return port. After the preset return time is reached, close the return solenoid valve to complete the disinfectant spraying.
[0031] S7: Open the first water inlet pump, the second water inlet pump, and the water inlet solenoid valve to allow water to flow through the pipeline into the rotating nozzle and the atomizing nozzle respectively, to rinse the medical instruments and tray on the support. When the preset cleaning time is reached, open the drain solenoid valve to let the sewage in the washing chamber enter the drain channel through the drain port. Then close the first water inlet pump, the second water inlet pump, the water inlet solenoid valve, and the drain solenoid valve to achieve the third clean water spray.
[0032] S8: Open the drying unit to dry the medical instruments and trays in the washing chamber. After the preset drying time is reached, close the drying unit and turn on the exhaust fan to expel the hot air carrying water vapor from the washing chamber.
[0033] S9: The door cover is opened by the lifting component, exposing the cleaned medical instruments and trays for easy collection by medical staff.
[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0035] (1) The fully automatic medical device cleaning and disinfection equipment provided by the present invention facilitates the placement and retrieval of medical devices through the lifting component, eliminating the need for medical staff to bend over to operate, saving time and effort. Moreover, the opening of the washing chamber is set upward and closed on all sides. When the door is closed, the entire washing chamber forms a complete sealed space, thereby avoiding leakage. In addition, the washing chamber is opened or closed by moving the door in the vertical direction, thereby solving the problem of increasing the space of the entire equipment in the horizontal plane when the door is opened, thus realizing the use of the equipment in a smaller area and improving the flexibility of equipment use.
[0036] (2) In this embodiment, the second support is arranged in multiple layers to increase the number of medical device placement positions without increasing the size of the entire support. Moreover, the movement of the support is vertical. Setting the second support in multiple layers not only matches the movement of the support, but also improves the utilization rate of the internal space of the washing chamber.
[0037] (3) The second support, which is stacked, is generally located in the center of the closed end of the first support, so that there are gaps between the two sides of the second support and the corresponding sides of the open end of the first support. This gap can be used to place the tray, so that the medical device and the tray used to hold the medical device can be cleaned, sterilized, disinfected and dried at the same time. This solves the problem of increased time caused by cleaning, sterilizing, disinfecting and drying the tray and the medical device separately. On the other hand, it avoids the problem of cross-contamination when the medical device is placed on the tray after processing, thereby improving the safety of the use of the medical device.
[0038] (4) The bottom of the washing chamber is formed by converging from all sides towards the center to prevent wastewater, enzyme solution, and disinfectant solution from remaining at the bottom of the washing chamber after cleaning medical devices. At the same time, it prevents them from adhering to the medical devices and trays again during the circulation cleaning, ensuring the cleanliness and tidiness of the bottom of the washing chamber and the cleaning effect. In addition, a sunken protrusion is set in the center of the washing chamber. On the one hand, it is to facilitate the setting of the first liquid inlet and the second liquid inlet and facilitate the connection of pipes. On the other hand, it allows the enzyme solution and disinfectant solution to enter the protrusion first after entering the washing chamber, and then fully mix with the clean water sprayed from the nozzle before circulating, thereby improving the reliability of medical device cleaning.
[0039] (5) The nozzles on the washing chamber are configured as atomizing nozzles, allowing the enzyme solution or disinfectant to quickly and evenly cover the surface of the medical device or tray in a mist form. This reduces the amount of enzyme solution or disinfectant used per cleaning cycle and minimizes impact on the medical device, preventing damage during cleaning. Additionally, the nozzles on the door cover are configured as rotating nozzles, allowing for 360° rotation to avoid cleaning blind spots and improve cleaning efficiency.
[0040] (6) By setting up a drying component, the medical devices and trays are kept dry after cleaning and can be used directly without the need for drying by other equipment or by air drying, which improves work efficiency and ensures the cleanliness and hygiene of the medical devices.
[0041] (7) The reason for adding a foot switch is that when medical staff have medical devices in their hands and cannot manually operate the on / off switch on the control panel, they can use their feet to step on the foot switch to control the lifting components to rise and fall, making the equipment more flexible and convenient.

[0061] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0062] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0063] like Figures 1 to 10 As shown, the present invention provides a fully automatic medical device cleaning and disinfection device, comprising:
[0064] A cabinet 100 with a supporting plane has a recessed washing chamber 110 formed along the supporting plane. The bottom of the washing chamber 110 is provided with a first inlet 111 for inputting disinfectant, a second inlet 112 for inputting enzyme solution, and an outlet 113 connected to a T-junction. A water inlet 120 and an outlet 130 are provided on the side of the cabinet 100 away from the supporting plane. The first port of the T-junction connected to the outlet 113 is connected to the washing chamber 110, and the second port of the T-junction is connected to the outlet 130 through a pipeline to form a drainage channel.
[0065] The disinfectant container 200 is used to store disinfectant solution, and the enzyme container 300 is used to store enzyme solution. The disinfectant container 200 is provided with a first outlet 210 and a return outlet 220. The first outlet 210 is connected to the first inlet 111 through a pipeline to form an inlet channel for disinfectant solution, and the return outlet 220 is connected to the third port of a tee through a pipeline to form a return channel for disinfectant solution. The enzyme container 300 is provided with a second outlet 310, which is connected to the second inlet 112 to form an inlet channel for enzyme solution.
[0066] The lifting assembly 400 is installed inside the cabinet 100, and the output end of the lifting assembly 400 can move up and down along the opening direction of the washing chamber 110, wherein the output end of the lifting assembly 400 can penetrate the support plane.
[0067] A door cover 500 is connected to the output end of a lifting assembly 400. The door cover 500 closes or opens the opening of the washing chamber 110 by moving the output end of the lifting assembly 400. A bracket is provided on the side of the door cover 500 facing the washing chamber 110, and multiple positions for placing medical devices are provided on the bracket. When the door cover 500 closes the opening of the washing chamber 110, the bracket is located inside the washing chamber 110; when the opening of the washing chamber 110 is fully open, the bracket is located outside the washing chamber 110.
[0068] Among them, a nozzle for inputting washing water is provided on the door cover 500 or the cavity wall of the washing chamber 110. The nozzle is connected to the water inlet 120 through a pipeline to form a water inlet channel for clean water.
[0069] It is worth mentioning that, initially, the cover 500 is in the open state, and the support is located outside the washing chamber 110 and is completely exposed. When medical staff place the medical device to be processed on the workstation, the lifting component 400 moves the cover 500 along the direction close to the opening of the washing chamber 110, allowing the support to slowly enter the washing chamber 110. When the cover 500 is completely closed to the opening of the washing chamber 110, the support is fully inside the washing chamber 110. At this time, the medical device on the support can be cleaned, sterilized, disinfected, and dried. After the medical device has been cleaned, sterilized, disinfected, and dried, the lifting component 400 moves the cover 500 again along the direction away from the opening of the washing chamber 110. As the cover 500 moves, it pulls the medical device on the support away from the washing chamber 110. When the cover 500 reaches the preset position, that is, when the opening of the washing chamber 110 is fully open, the medical device on the support is completely above the opening of the washing chamber 110. At this time, medical staff can remove the medical device from the support.
[0070] This invention provides a fully automatic medical device cleaning and disinfection device. The lifting assembly 400 facilitates the placement and retrieval of medical devices, eliminating the need for medical personnel to bend over, saving time and effort. Furthermore, the washing chamber 110 has its opening facing upwards and is enclosed on all sides. When the door 500 closes the opening of the washing chamber 110, the entire washing chamber 110 forms a completely sealed space, thus preventing leakage. In addition, the washing chamber 110 can be opened or closed by moving the door 500 vertically, thus solving the problem of increased horizontal space required when the door 500 is open. This allows the device to be used in a smaller area, improving its flexibility.
[0071] Preferably, the support includes a first support 510 arranged in a U-shape, and the two sides of the open end of the first support 510 are connected to the door cover 500; a second support 520 is formed by multiple layers, and the second support 520 is connected to the closed end of the first support 510, wherein there are gaps between the two sides of the second support 520 and the corresponding sides of the open end of the first support 510, and the workstation is set on the second support 520.
[0072] It is worth mentioning that the second support 520 in this embodiment is arranged in multiple layers. This is to increase the number of medical device placement positions without increasing the overall size of the support. Moreover, since the movement of the support is vertical, arranging the second support 520 in multiple layers not only matches the movement pattern of the support but also improves the utilization rate of the internal space of the washing chamber 110. The structural design of the second support 520 is not limited to a layered arrangement; it can also be laid flat and connected to the closed end of the first support 510, or in other ways.
[0073] In addition, the second support 520, which is stacked in layers, is generally positioned in the center of the closed end of the first support 510, so that there are gaps between the two sides of the second support 520 and the corresponding sides of the open end of the first support 510. These gaps can be used to place a tray, so that the medical device and the tray used to hold the medical device can be cleaned, sterilized, disinfected and dried at the same time. This solves the problem of increased time caused by cleaning, sterilizing, disinfecting and drying the tray and the medical device separately, and avoids the problem of cross-contamination when the medical device is placed on the tray after processing, thereby improving the safety of medical device use.
[0074] Preferably, the bottom of the washing chamber 110 is conical, and the four sides of the bottom of the washing chamber 110 converge obliquely towards the central liquid outlet 113. A recessed boss 114 is provided at the liquid outlet 113, and the first liquid inlet 111, the second liquid inlet 112 and the liquid outlet 113 are provided on the boss 114.
[0075] In this embodiment, the bottom of the washing chamber 110 is designed so that the surrounding areas converge towards the center to prevent wastewater, enzyme solution, and disinfectant solution from remaining at the bottom of the washing chamber 110 after cleaning the medical devices. This also prevents these substances from re-adhering to the medical devices and trays during the cyclic cleaning process, ensuring the cleanliness and effectiveness of the bottom of the washing chamber 110. In addition, a recessed protrusion 114 is provided at the center of the washing chamber 110. This serves two purposes: firstly, it facilitates the installation of the first liquid inlet 111 and the second liquid inlet 112, making pipe connections easier; secondly, it ensures that the enzyme solution and disinfectant solution, after entering the washing chamber 110, first enter the protrusion 114 and then mix thoroughly with the clean water sprayed from the nozzle before circulating, thereby improving the reliability of medical device cleaning.
[0076] Preferably, the nozzle includes a plurality of atomizing nozzles 115 disposed on the cavity wall of the washing chamber 110 and a rotating nozzle 530 disposed on the door cover 500. The plurality of atomizing nozzles 115 are evenly distributed on the cavity wall of the washing chamber 110, and the spraying direction of the plurality of atomizing nozzles 115 is towards the middle position of the washing chamber 110. The rotating nozzle 530 is disposed on the side of the door cover 500 facing the washing chamber 110 and located above the washing chamber 110.
[0077] It is worth mentioning that the nozzle on the washing chamber 110 is configured as an atomizing nozzle 115, which allows the enzyme solution or disinfectant to quickly and evenly cover the surface of the medical device or tray in a mist. This reduces the amount of enzyme solution or disinfectant used per cleaning cycle, and the atomizing nozzle 115 also reduces the impact on the medical device, preventing damage during the cleaning process. Furthermore, the nozzle on the cover 500 is configured as a rotating nozzle 530, allowing for 360° rotation, eliminating blind spots and improving cleaning efficiency.
[0078] Furthermore, it is pointed out that when cleaning medical devices, the medical devices are laid flat on the workstation, so that the rotating nozzle 530 is aimed at the side of the medical device. Even if the water jet from the rotating nozzle 530 has a large impact, it will not damage the medical device. Moreover, it can wash away the enzyme solution or disinfectant solution adhering to the surface of the medical device, thus improving the cleaning effect.
[0079] Preferably, the lifting assembly 400 includes:
[0080] A linear motor 410 is provided, and the linear motor 410 is arranged vertically, wherein the linear motor 410 is provided with a slide rail 420;
[0081] The slider 430 is slidably connected to the slide rail 420, and is driven by the linear motor 410 to move linearly on the slide rail 420;
[0082] The lifting rod 440 is connected to the slider 430 at one end and to the door cover 500 at the other end. The slider 430 drives the door cover 500 to move up and down in the vertical direction via the lifting rod 440, thereby opening and closing the opening of the washing chamber 110.
[0083] It is worth mentioning that two limit switches 450 are provided on the slide rail 420, and the two limit switches 450 are set up and down along the sliding direction of the slider 430. One limit switch 450 controls the upward stroke of the lifting rod 440, and the other limit switch 450 controls the downward stroke of the lifting rod 440.
[0084] When the slider 430 approaches the limit switch 450 on the side away from the bottom of the washing chamber 110, the lifting rod 440 stops rising. At this time, the support is outside the washing chamber 110, making it convenient for medical staff to place or retrieve medical instruments and trays. When the slider 430 approaches the limit switch 450 near the bottom of the washing chamber 110, the lifting rod 440 stops descending. At this time, the support is inside the washing chamber 110, and the opening of the washing chamber 110 is closed, making the entire washing chamber 110 a sealed space for cleaning medical instruments and trays.
[0085] In this embodiment, by setting two limit switches 450, the distance of the lifting rod 440 rising and falling is strictly controlled, thereby improving the reliability of medical device and tray cleaning.
[0086] Preferably, both the disinfectant container 200 and the enzyme container 300 are equipped with a liquid level sensor 230, which facilitates real-time detection of the corresponding liquid content in the disinfectant container 200 and the enzyme container 300, and facilitates timely replenishment of the disinfectant and enzyme.
[0087] Preferably, the disinfectant container 200 extends to a detection port 240, and a dispensing pump 250 is provided between the detection port 240 and the disinfectant container 200. The dispensing pump 250 draws the disinfectant from the disinfectant container 200 to the detection port 240 to detect the concentration of the disinfectant.
