Description

Technical Field

[0001] This utility model relates to the field of medical cleaning and disinfection equipment technology, and in particular to an intelligent dual-cylinder endoscope cleaning and disinfection machine. Background Technology

[0002] Endoscope sterilizers are specialized devices used for cleaning and sterilizing endoscopes, ensuring their safety and hygiene during medical procedures. As invasive medical devices, endoscopes come into direct contact with patients' bodily fluids and tissues; therefore, they must undergo rigorous sterilization and disinfection to prevent cross-infection and disease transmission. Endoscope sterilizers typically use aldehyde disinfectants such as glutaraldehyde to kill pathogenic microorganisms. The disinfectant solution and water are heated during cleaning and sterilization, generating residual heat typically ranging from 60℃ to 100℃, and the waste heat during cooling reaches 30℃ to 80℃.

[0003] However, the existing technology still has the following drawbacks:

[0004] 1. Existing endoscope sterilization machines typically trigger an alarm via an alarm module when the concentration of the sterilizing solution is insufficient, prompting staff to manually replenish the concentrate or replace the sterilizing solution in the sterilization tank. In addition, some cleaning and sterilization machines are equipped with automatic replacement of the concentrate in the sterilizing stock solution tank, but they still cannot predict the effectiveness of the sterilizing solution in the sterilization tank, nor can they automatically replenish the concentrate or replace the sterilizing solution based on the predicted effectiveness.

[0005] 2. Existing endoscope sterilization machines cannot recover and rationally utilize the waste heat generated during the preheating and cooling processes of the equipment after sterilization, which exacerbates the greenhouse effect and wastes energy. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent dual-cylinder endoscope cleaning and disinfection machine.

[0007] The purpose of this utility model is achieved by the following technical solution: an intelligent dual-cylinder endoscope cleaning and disinfection machine, including a machine body, wherein the machine body is provided with a disinfection liquid tank, a concentrated liquid tank, a clean water pipe, a drain pipe and several disinfection cylinders; the machine body is also provided with a main control module and a liquid electric pump, a data acquisition module, a data processing module and a control valve assembly respectively electrically connected to the main control module;

[0008] The control valve assembly includes a first control valve, a second control valve, a third control valve, and a fourth control valve, which are respectively used to connect the concentrate tank, the disinfectant tank, the clean water pipe, the drain pipe, and the disinfection cylinder.

[0009] When the data acquisition module detects that the effectiveness of the disinfectant in the disinfection tank is lower than the preset threshold stored in the data processing module, the main control module controls the first control valve to open and starts the liquid electric pump to pump the concentrate from the concentrate tank into the disinfection tank in a metered manner; when the data acquisition module detects that the usage time and effectiveness of the disinfectant in the disinfection tank have reached the replacement conditions stored in the data processing module, the main control module sequentially controls the fourth control valve to open and empty the old liquid in the disinfection tank, and the second control valve to open and start the liquid electric pump to pump the disinfectant from the disinfectant tank into the disinfection tank in a metered manner.

[0010] Furthermore, the machine body is also equipped with a waste heat collection system electrically connected to the main control module. The waste heat collection system includes a heat pump unit, a heat exchanger, and a temperature sensor. The heat exchanger is installed at the heat exhaust port of the machine body, and the heat pump unit is connected to the disinfection tank and each pipe through pipelines.

[0011] When the temperature sensor detects that the waste heat temperature is lower than the preset value stored in the data processing module, it sends a feedback signal to the main control module to send an instruction to control the heat exchanger to transfer heat to the heat pump unit for heating and then selectively pump it to each disinfection tank or pipeline for preheating and / or drying.

[0012] Alternatively, when the temperature sensor detects that the waste heat temperature meets the preset value stored in the data processing module, it sends a feedback signal to the main control module to send an instruction to control the heat exchanger to transfer heat to the heat pump unit and selectively pump it to each disinfection tank or pipeline for preheating and / or drying.

[0013] Furthermore, the machine body is also provided with a heat gas collection chamber, which is connected to the heat pump unit, so that the main control module can send instructions to control the heat pump unit to pump the excess heat to the heat gas collection chamber.

[0014] Furthermore, the data acquisition module includes an electrochemical sensor and a turbidity sensor installed inside the disinfection tank for detecting the concentration of the disinfectant solution. Both the electrochemical sensor and the turbidity sensor establish a real-time data communication connection with the main control module.

[0015] Furthermore, the machine body is equipped with a disinfection heater that is electrically connected to the main control module. The disinfection heater is connected to the disinfection tank pipeline and delivers heat to heat the disinfection solution and / or clean water. The main control module sends instructions to control the disinfection heater to heat according to the heating threshold value pre-stored by the data acquisition module, and feeds back the heating temperature to the main control module in real time for PID adjustment.

[0016] Furthermore, the top of the machine body is provided with an adjustment arm, and the adjustment arm is provided with a display module electrically connected to the main control module. The display module generates and displays a three-dimensional heat map containing the concentration field distribution of the disinfectant through the data processing module, and simultaneously displays the disinfection temperature and disinfection time parameters in real time.

[0017] Furthermore, the machine body is equipped with a liquid circulation pump electrically connected to the main control module. The main control module sends commands to control the liquid circulation pump to make the liquid circulate during the disinfection and / or cleaning process of the disinfection tank.

[0018] Furthermore, the top of the machine body is provided with a transparent cover that corresponds to and closes each disinfection tank, and the transparent cover is provided with a flipping arm for driving it to flip open or close.

[0019] Furthermore, the machine body is equipped with a lifting motor, which is electrically connected to the main control module. The output end of the lifting motor is equipped with a lifting rod connected to the tilting arm, so that the lifting motor drives the lifting rod to rise and fall and drives the tilting arm and the transparent cover to open or close each disinfection tank.

[0020] Furthermore, the flipping arm is equipped with a spray pipe arranged inside the transparent cover. The spray pipe is connected to the disinfectant tank, the concentrate tank, and the clean water pipe. The end of the spray pipe is equipped with a spiral nozzle, and its spray direction forms an angle of 15-45° with the axis of the disinfection tank.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] (1) The embodiment of this application provides a data acquisition module that can detect the effectiveness of the disinfectant in the disinfection tank in real time, so that when the effectiveness of the disinfectant in the disinfection tank is low or needs to be replaced, a signal can be promptly fed back to the main control module; and by setting a data processing module, the disinfectant detection data can be compared and analyzed by receiving the instructions of the main control module, so that the main control module controls each control valve and liquid electric pump to perform actions according to the comparison and analysis signal, thereby realizing the automatic replenishment of concentrated disinfectant in the disinfection tank, or the automatic replacement of old disinfectant and replenishment of new disinfectant in the disinfection tank;

[0023] Compared to previous methods that relied solely on alarms to prompt staff to replenish or replace disinfectant solution, the embodiments of this application are more automated, reducing workload, maintaining the effectiveness of disinfectant solution in a timely manner, extending the time between disinfectant solution replacements, reducing raw material and labor costs, while improving the cleaning and disinfection effect of endoscopes. Moreover, combined with the optimized multi-cylinder configuration, it can improve work efficiency by at least 30%.

[0024] (2) By setting the heat exchanger of the waste heat collection system at the heat exhaust port of the machine, the residual heat and waste heat generated during the daily cleaning and disinfection of endoscopes by the cleaning and disinfection machine can be fully recovered; and a temperature sensor is set to detect the temperature of the discharged heat in real time. Through the coordinated action between the temperature sensor, data processing module, main control module and waste heat collection system, the temperature of the waste heat can be increased or directly used for drying and preheating of clean water according to the temperature of the discharged heat. Compared with the previous cleaning and disinfection machines that lacked waste heat recovery, the embodiments of this application reduce electricity or steam consumption by at least 20%-40% through waste heat collection and utilization and through estimation, reducing carbon emissions and the environmental impact of cooling tower heat dissipation. Moreover, long-term operation can save energy costs and shorten the equipment investment recovery period. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] like Figure 1-4 As shown, an intelligent dual-cylinder endoscope cleaning and disinfection machine includes a body 10 with a cavity inside. The front of the body 10 has a cabinet door 1011 and a control panel 1013, and the bottom of the body 10 has a base 1012. The cavity contains a disinfectant tank 104, a concentrate tank 105, a clean water pipe 106 (not shown in the structural diagram), a drain pipe 107 (not shown in the structural diagram), and several disinfection tanks 108. Specifically, two disinfection tanks 108 are installed side-by-side. Compared to the usual single-cylinder design, the cleaning and disinfection efficiency of the endoscope is significantly improved. The disinfectant tank 104, concentrate tank 105, clean water pipe 106, and drain pipe 107 are respectively connected to the two disinfection tanks 108. Furthermore, each disinfection tank 108 has an inlet 1014 for supplying disinfectant, concentrate, and clean water, and an air inlet 1015 for supplying heat.

[0039] The machine cavity also integrates a main control module 30, as well as a liquid electric pump 402, a data acquisition module 31, a data processing module 32, a control valve assembly 40, and a power module 34, all electrically connected to the main control module 30. A power switch 35 for controlling power on / off is provided within the machine cavity, and the power module 34 provides power to each functional module. The control valve assembly 40 in this embodiment includes a first control valve 50, a second control valve 51, a third control valve 52, and a fourth control valve 53. The first control valve 50 connects the concentrate tank 105 to the sterilization tank 108; the second control valve 51 connects the sterilization tank 104 to the sterilization tank 108; the third control valve 52 connects the clean water pipe 106 to the sterilization tank 108; and the fourth control valve 53 connects the drain pipe 107 to the sterilization tank 108. The control valve assembly 40 can be an electric valve.

[0040] The disinfectant management process of the cleaning and disinfection machine according to the embodiments of this application is divided into two aspects: replenishing the concentrate and replacing the disinfectant.

[0041] Regarding the replenishment of the concentrated solution, the data acquisition module 31 is used to detect the effectiveness of the disinfectant in the disinfection tank 108, and then feeds back the relevant detection data to the main control module 30. The main control module 30 receives the detection data and sends it to the data processing module 32 for comparison with the pre-stored set threshold. When the data acquisition module 31 detects that the effectiveness (such as concentration and turbidity) of the disinfectant in the disinfection tank 108 is lower than the pre-stored set threshold of the data processing module 32, the main control module 30 receives the feedback signal from the data processing module 32, and then sends a command to control the first control valve 50 to open and start the liquid electric pump 402 to pump the concentrated solution quantitatively into the disinfection tank 108 until the disinfectant in the disinfection tank 108 reaches a certain concentration and restores its disinfection effectiveness.

[0042] Regarding disinfectant replacement, when the data acquisition module 31 detects that the disinfectant usage time and effectiveness in the disinfection tank 108 have reached the replacement conditions pre-stored by the data processing module 32, the main control module 30 receives the feedback signal from the data processing module 32 and executes the following actions in sequence: First, the fourth control valve 53 is opened and the old disinfectant in the disinfection tank 108 is emptied through the drain pipe 107; then, the fourth control valve 53 is closed and the second control valve 51 is opened, and the liquid electric pump 402 is started to pump the new disinfectant from the disinfectant tank 104 to the disinfection tank 108 in a metered manner, thereby automatically completing the real-time detection and replacement of disinfectant.

[0043] Furthermore, an alarm module can also be installed inside the machine cavity in this embodiment. This alarm module is electrically connected to the main control module 30. When the main control module 30 receives a feedback signal from the data acquisition module 31 indicating that the disinfectant solution in the disinfection tank 108 is insufficient or needs to be replaced, the main control module 30 sends a command to control the alarm module to alert the staff. The staff can then re-check the disinfectant solution treatment status as needed. When the disinfectant solution in the disinfection tank 108 is replenished or replaced, the main control module 30 can control the alarm module to stop its alarm action.

[0044] Thus, based on the optimized and improved technical solution of the above-mentioned disinfection machine, the data acquisition module 31 can detect the effectiveness of the disinfectant in the disinfection tank 108 in real time, so that when the effectiveness of the disinfectant in the disinfection tank 108 is low or needs to be replaced, a timely feedback signal can be sent to the main control module 30; and by setting up the data processing module 32, the main control module 30 receives the instructions from the main control module 30 to compare and analyze the disinfectant detection data, so that the main control module 30 controls each control valve and the liquid electric pump 402 to perform actions according to the comparison and analysis signals, thereby realizing the automatic replenishment of concentrated disinfectant in the disinfection tank 108, or the automatic replacement of old disinfectant and replenishment of new disinfectant in the disinfection tank 108;

[0045] Compared to previous methods that relied solely on alarms to prompt staff to replenish or replace disinfectant solution, the embodiments of this application are more automated, reducing workload, maintaining the effectiveness of disinfectant solution in a timely manner, extending the time between disinfectant solution replacements, reducing raw material and labor costs, while improving the cleaning and disinfection effect of endoscopes. Moreover, combined with the optimized multi-cylinder configuration, it can improve work efficiency by at least 30%.

[0046] In practical applications, the data acquisition module 31 of this embodiment employs an electrochemical sensor and a turbidity sensor embedded in the disinfection tank 108. Both the electrochemical sensor and the turbidity sensor establish real-time data communication connections with the main control module 30. Therefore, under the control of the main control module 30, the concentration and turbidity of the disinfectant are monitored in real time, and the relevant data are transmitted to the main control module 30 via wireless communication. The specific detection methods of the electrochemical sensor and the turbidity sensor are prior art and will not be described further in this embodiment.

[0047] In the process of disinfecting and / or cleaning endoscopes, the cleaning and disinfection machine of this application embodiment can recover and utilize waste heat. Specifically, a waste heat collection system 20 is added inside the machine cavity, and the waste heat collection system 20 is electrically connected to the main control module 30. The waste heat collection system 20 includes a heat pump unit 401, a heat exchanger, and a temperature sensor.

[0048] The unit 10 is equipped with a heat exhaust port (not shown in the structural diagram) for discharging waste heat, such as heat emitted during the operation of steam condensate pipes and cooling water circuits. Therefore, a heat exchanger can be installed at the heat exhaust port of the unit 10. Additionally, the heat pump unit 401 is connected to the sterilization tank 108 and various pipes via piping. The heat pump unit 401 includes an evaporator, a compressor, and a condenser. A temperature sensor is installed on the heat exhaust pipe and is used to monitor the temperature of the discharged waste heat in real time.

[0049] Regarding the waste heat control logic, if the temperature sensor detects that the waste heat temperature is lower than the preset value (e.g., 40℃) stored in the data processing module 32, the data processing module 32 sends a feedback signal to the main control module 30. The main control module 30 sends an instruction to control the heat exchanger to transfer heat to the heat pump unit 401 according to the feedback signal. After the heat pump unit 401's compressor heats up the heat, it is then selectively released through the condenser to the disinfection tank 108 to dry the cleaned and disinfected endoscope, or released to various pipelines to dry, or released to the clean water pipeline 106 to preheat the clean water.

[0050] If the temperature sensor detects that the waste heat temperature is equal to or higher than the preset value stored in the data processing module 32 (e.g., ≥80℃), the data processing module 32 sends a feedback signal to the main control module 30. The main control module 30 sends a command according to the feedback signal to control the heat exchanger to transfer the heat to the heat pump unit 401, and then selectively releases the heat directly to the disinfection tank 108 through the condenser to dry the cleaned and disinfected endoscope, or releases it to various pipelines to dry, or releases it to the clean water pipeline 106 to preheat the clean water.

[0051] The unit 10 is also equipped with a hot air collection chamber, which is connected to the heat pump unit 401. The main control module 30 sends instructions to control the heat pump unit 401 to transfer some of the heat to the hot air collection chamber for subsequent disinfection cycle.

[0052] Therefore, by placing the heat exchanger of the waste heat collection system 20 at the heat exhaust port of the machine body 10, the residual heat and waste heat generated during the daily cleaning and disinfection of endoscopes by the cleaning and disinfection machine can be fully recovered. Furthermore, a temperature sensor is installed to monitor the temperature of the discharged heat in real time. Through the coordinated action of the temperature sensor, data processing module 32, main control module 30, and waste heat collection system 20, the waste heat can be temperature-boosted or directly used for drying or preheating clean water based on its temperature. Compared to previous cleaning and disinfection machines that lacked waste heat recovery, this embodiment of the application, through waste heat collection and utilization and estimation, reduces electricity or steam consumption by at least 20%-40%, reduces carbon emissions and the environmental impact of cooling tower heat dissipation, and saves energy costs and shortens the equipment investment payback period in the long term.

[0053] In this embodiment of the application, when cleaning and disinfecting an endoscope, the cleaning and disinfection machine needs to heat the disinfectant and clean water through a disinfection heater 60 installed in the machine cavity. The disinfection heater 60 is connected to the disinfection tank 108 through a pipe, so the disinfection heater 60 can release the heat generated to the disinfection tank 108.

[0054] The disinfection heater 60 is electrically connected to the main control module 30. In actual operation, the disinfection tank 108 can also be embedded with a temperature sensor to detect the temperature of the disinfectant and / or clean water in the disinfection tank 108 in real time, so that the main control module 30 can send a command to start the disinfection heater 60 according to the temperature sensor data, and use a PID algorithm to dynamically adjust the temperature (such as maintaining 95±5℃) to ensure the activity of the disinfectant.

[0055] To further improve the uniform distribution of disinfectant solution in the disinfection tank 108 and maintain uniform concentration and temperature of the disinfectant solution, a liquid circulation pump 403 is installed inside the machine cavity. This liquid circulation pump 403 is electrically connected to the main control module 30. Therefore, the main control module 30 sends commands to control the liquid circulation pump 403 to circulate the liquid during the disinfection and / or cleaning process of the disinfection tank 108.

[0056] By continuously circulating the disinfectant solution, it ensures even coverage of the endoscope surface and internal channels, improving disinfection effectiveness; maintains a consistent disinfectant concentration, preventing localized concentration drops and ensuring stable disinfection results; through circulation, the disinfectant solution can reach all parts of the endoscope more quickly and effectively, shortening disinfection time; and helps maintain uniform disinfectant temperature, ensuring consistent disinfection results. In summary, the function of the liquid circulation pump 403 is to ensure uniform distribution of the disinfectant solution, maintain concentration, improve efficiency, clean residues, maintain uniform temperature, and extend the lifespan of the disinfectant solution.

[0057] An adjusting arm 103 is located on the top of the main body 10, and a display module 33 is mounted on the adjusting arm 103. The display module 33 is electrically connected to the main control module 30. Under the command and control of the main control module 30, the display module generates and displays a three-dimensional heat map containing the concentration field distribution of the disinfectant through the data processing module 32, and simultaneously displays the disinfection temperature and disinfection time parameters in real time. When necessary, more data can be added to the display parameters of the display module 33, such as cleaning and disinfection history records and trend analysis. In addition, the main control module 30 can be communicatively connected to the hospital's information system to automatically record disinfection data for easy traceability and management. Furthermore, human-machine interaction is achieved through the touch display module 33, and the adjusting arm 103 can be adjusted to multiple angles according to user needs, improving user convenience.

[0058] To further improve the safety of the cleaning and disinfection machine, a transparent cover 101 is provided on the top of the machine body 10 to cover each disinfection tank 108. The transparent cover 101 facilitates observation of the cleaning and disinfection operation inside the disinfection tank 108. In actual use, the material of the transparent cover 101 can be selected to be anti-fog or anti-scratch, so as to keep the inside of the disinfection tank 108 clearly visible during operation.

[0059] A flipping arm 102 is provided on the transparent cover 101, with one end of the flipping arm 102 extending towards the rear edge of the machine body 10. A lifting motor 70 is installed inside the machine cavity, electrically connected to the main control module 30. The output end of the lifting motor 70 has a vertically positioned lifting rod 1010, connected to one end of the flipping arm 102 at the upper end of the lifting rod 1010. Therefore, when the lifting motor 70 drives the lifting rod 1010 to move vertically up and down, the lifting rod 1010 synchronously pulls and drives the flipping arm 102, controlling the transparent cover 101 to flip up and down around the edge where the flipping arm 102 is connected to the lifting rod 1010, thereby opening or closing each disinfection tank 108. By automatically opening and closing the transparent cover 101, the user does not need to operate it manually, reducing the risk of contamination.

[0060] A spray pipe 109 is provided inside the transparent cover 101. Since the transparent cover 101 has a rotating arm 102, which is hollow, a flexible pipe connecting to the spray pipe 109 can be arranged inside the rotating arm 102. This arrangement of the flexible pipe inside the rotating arm 102 is both simple and aesthetically pleasing. The spray pipe 109 is connected to the disinfectant tank 104, the concentrate tank 105, and the clean water pipe 106 through these flexible pipes. A spiral nozzle is provided on the lower side of the spray pipe 109, and its spray direction forms a 15-45° angle with the axis of the disinfection tank 108, resulting in a better spraying effect on the endoscope.

[0061] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
