Description

Technical Field

[0001] This utility model relates to the field of medical device disinfection technology, specifically to a fully automatic endoscope cleaning machine. Background Technology

[0002] Endoscopes are reusable diagnostic and therapeutic instruments used for observation and surgery inside the human body. Due to their precise structure, complex lumens, special materials, and difficulty in cleaning, they are unsuitable for high-temperature and high-pressure sterilization. Most endoscopes are sterilized by immersion in chemical disinfectants. Proper cleaning and disinfection are crucial for preventing and controlling cross-infection. Currently, traditional endoscope cleaning and disinfection methods mainly rely on chemical disinfectants, which presents the following problems: chemical disinfectant residues may remain, posing a health risk to humans and the environment; the cleaning and disinfection process relies on manual operation, resulting in low efficiency and a high risk of errors; and the disinfection process is time-consuming, making it difficult to meet the needs of efficient turnover. Therefore, an automated endoscope cleaning device is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a fully automatic endoscope cleaning machine, which solves the problems of low automation, susceptibility to contamination by the injured, and difficulty in self-cleaning of internal pipes in existing endoscope cleaning equipment.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] The fully automatic endoscope cleaning machine includes a housing, a first cleaning tank mounted on the housing, and a liquid supply system installed inside the housing. The first cleaning tank contains a cleaning platform with a drain outlet at the bottom. An endoscope connecting frame is mounted on the top of the cleaning platform, and a liquid inlet is located on the endoscope connecting frame. The liquid supply system is connected to the liquid inlet. The cleaning liquid output from the liquid supply system through the liquid inlet rinses and disinfects the endoscopes on the endoscope connecting frame. The cleaned liquid flows back into the first cleaning tank, effectively preventing liquid from splashing and contaminating the endoscopes, ensuring high cleaning safety.

[0006] Furthermore, the liquid supply system includes an ozone water generator, a multi-way solenoid valve, an alcohol tank, an enzyme tank, and a disinfectant tank. One end of the multi-way solenoid valve is connected to the liquid inlet, and the other end is connected to the ozone water generator, the alcohol tank, the enzyme tank, and the disinfectant tank, respectively. This allows control over the entry of different liquids into the first cleaning tank. By controlling the amount and ratio of each cleaning liquid through the multi-way solenoid valve, the system can meet the disinfection needs of different endoscopes. The generated ozone water can also be used for cleaning internal pipes.

[0007] Furthermore, the chamber is equipped with a monitoring system, which includes a side leak detection device, a water flow sensor, a temperature sensor, a humidity sensor, an ozone concentration sensor, a pressure sensor, a TDS sensor, and a time relay. The water flow sensor, temperature sensor, humidity sensor, ozone concentration sensor, pressure sensor, TDS sensor, and time relay are all integrated into a multi-way solenoid valve. The side leak detection device is located on the inner wall of the chamber and is used to detect various parameters of the disinfectant solution used for cleaning, thereby improving the safety of disinfection.

[0008] In this preferred configuration, the housing is also equipped with a control system, which includes a display panel, buttons, and a control circuit board. The control circuit board is located on the inner wall of the housing, while the display panel and buttons are located on the outer wall of the housing, and are used to manually set cleaning parameters.

[0009] As an even better feature, the chamber is also equipped with a supply system, which includes an integrated air compressor, a reverse osmosis filter, a water inlet pipe, and a drain pipe. The integrated air compressor is connected to the endoscope connecting frame, one end of the reverse osmosis filter is connected to the water inlet pipe, and the other end is connected to the ozone water generator. The drain pipe is connected to the liquid inlet to improve the cleanliness of the water source. The air compressor outputs air to dry the endoscope, improving the cleaning efficiency.

[0010] Even better, it also includes an RFID module, which is installed on the outer wall of the housing to record parameters for cleaning the endoscope, for traceability purposes.

[0011] Even better, a contactless detection module is also included, which is located on the lower part of the outer wall of the enclosure to prevent human contact from causing contamination.

[0012] Even better, it also includes an automatic tank cover, which is connected to the housing and closes to the opening of the first cleaning tank when closed, preventing liquid splashing and external environmental contamination of the endoscope.

[0013] As an even better option, multiple liquid inlets are located on the outer wall of the endoscope connecting frame, which allows for all-round disinfection of the endoscope.

[0014] Furthermore, it also includes a second cleaning tank, which is installed on the housing and has the same structure as the first cleaning tank. This allows for the simultaneous cleaning of multiple endoscopes, improving the cleaning efficiency of the endoscopes.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The fully automatic endoscope cleaning machine is equipped with a first cleaning tank and a liquid supply system. The first cleaning tank is equipped with a cleaning platform, and an endoscope connecting frame is installed on the cleaning platform to fix and prevent the liquid from being contaminated during repeated rinsing. The endoscope connecting frame is equipped with a liquid inlet for connecting the liquid supply system to thoroughly clean the endoscope. After fixing the endoscope, it can be fully and automatically rinsed without human intervention, and the cleaning efficiency and safety are high.

[0017] (2) The liquid supply system of the fully automatic endoscope cleaning machine is equipped with an electrolytic ozone water generating device, which can generate ozone water through electrolysis of water. The ozone water is used to rinse the endoscope and the internal liquid supply water circuit, ensuring the safety of cleaning and preventing the formation of biofilm in the internal water circuit, which would cause endoscope contamination. The liquid supply system is also equipped with an enzyme liquid tank, an enzyme liquid tank and a disinfectant liquid tank, which can be used individually or in combination to meet different types of disinfection treatment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Example 1

[0029] like Figures 1-7 As shown, this embodiment discloses a fully automatic endoscope cleaning machine, including a housing 1, a first cleaning tank 11 disposed on the housing 1, and a liquid supply system 3 disposed inside the housing 1. The first cleaning tank 11 is provided with a cleaning platform 13, and a drain port 17 is provided at the bottom of the first cleaning tank 11. An endoscope connecting frame 14 is provided at the top of the cleaning platform 13, and a liquid inlet 15 is provided on the endoscope connecting frame 14. The liquid supply system 3 is connected to the liquid inlet 15. Both the cleaning platform 13 and the endoscope connecting frame 14 are lower than the opening surface of the first cleaning tank 11. The endoscope is fixed to the endoscope connecting frame 14. The liquid supply system 3 outputs cleaning liquid through the liquid inlet 15 to rinse and disinfect the endoscope. After passing through the endoscope, the disinfecting liquid flows down onto the cleaning platform 13, then enters the bottom of the first cleaning tank 11, and is discharged outward through the drain port 17. During the cleaning process, the cleaning liquid flows downward to prevent backflow and splashing, which could contaminate the endoscope.

[0030] Furthermore, the liquid supply system 3 includes an ozone water generating device 31, a multi-way solenoid valve 33, an alcohol tank 34, an enzyme liquid tank 35, and a disinfectant liquid tank 36. One end of the multi-way solenoid valve 33 is connected to the liquid inlet 15, and the other end of the multi-way solenoid valve 33 is connected to the ozone water generating device 31, the alcohol tank 34, the enzyme liquid tank 35, and the disinfectant liquid tank 36 respectively. This allows control over the different liquids in the ozone water generating device 31, the alcohol tank 34, the enzyme liquid tank 35, and the disinfectant liquid tank 36 to enter the first cleaning tank 11. The device 31 uses water electrolysis to generate ozone. The ozone dissolves in the water to form ozone water, which can be used to directly clean the endoscope and also to clean the internal water circuit. Alcohol can be stored in the alcohol tank 34, enzyme can be stored in the enzyme tank 35, and a certain amount of chemical cleaning agent can be stored in the disinfectant tank 36. The multi-port solenoid valve 33 can control the entry of liquids individually or simultaneously control the mixing of liquids in multiple tanks. Alcohol, biological enzymes and cleaning agents are mixed and then fed into the liquid inlet 15 to meet different requirements for comprehensive disinfection and sterilization.

[0031] A door 32 is provided on the outer side wall of the box body 1. The alcohol compartment 34, enzyme compartment 35 and disinfectant compartment 36 are located near the door 32. Opening the door 32 allows various disinfectant liquids to be added to the alcohol compartment 34, enzyme compartment 35 and disinfectant compartment 36.

[0032] Preferably, the ozone water generating device 31 comprises an electrolytic ozone generator, a water supply pump, a water flow sensor, and an ozone water concentration sensor. The electrolytic ozone generator uses boron-doped diamond electrodes, which has the advantages of high electrolysis efficiency and no byproducts in ozone generation. It can also be used in conjunction with traditional disinfectants, playing different roles in different cleaning modes. The water supply pump is used to fill the water source and externally transport the generated ozone water. The water flow sensor is used to detect the water flow rate to control the ozone generation rate. The ozone water concentration sensor is used to detect the concentration of the generated ozone water to prevent insufficient ozone concentration from causing a decrease in disinfection effect.

[0033] Furthermore, the enclosure 1 is equipped with a monitoring system 4, which includes a side leak detection device, a water flow sensor, a temperature sensor, a humidity sensor, an ozone water concentration sensor, a pressure sensor, a TDS sensor, and a time relay. The water flow sensor, temperature sensor, humidity sensor, ozone water concentration sensor, pressure sensor, TDS sensor, and time relay are all integrated into a multi-way solenoid valve 33, which is used to detect the flow rate, pressure, and other data of the liquid passing through and transmit them to the display panel 22 for easy viewing by operators. The side leak detection device is set on the inner wall of the enclosure 1 to detect whether there are any leaks inside, so as to prevent the growth of bacteria inside.

[0034] The ozone water generating device 31 can start and stop according to the water flow change signal of the water flow sensor to prevent the ozone generator from burning dry and being damaged. It can also supply power to the ozone generator according to the current and voltage signals of the water flow sensor to ensure the stability of the ozone water concentration generated under different flow conditions.

[0035] Preferably, the housing 1 is further provided with a control system 2. The control system 2 includes a display panel 22, buttons 21 and a control circuit board 23. The control circuit board 23 is located on the inner side wall of the housing 1, and the display panel 22 and buttons 21 are located on the outer wall of the housing 1. The control circuit board 23 is used to receive internal monitoring signals and control the operation of the liquid supply system 3. The display panel 22 is used to display the working status of the liquid supply system 3 and show the execution time of the automatic cleaning program. The buttons 21 are used to set the type of cleaning liquid to be added, the mixing ratio and the duration parameters.

[0036] More preferably, the housing 1 is also equipped with a supply system, which includes an integrated air compressor 38, a reverse osmosis filter 39, a water inlet pipe 381, and a drain pipe 382. The integrated air compressor 38 is connected to the endoscope connecting frame 14. One end of the reverse osmosis filter 39 is connected to the water inlet pipe 381, and the other end is connected to the ozone water generating device 31. The drain pipe 382 is connected to the liquid inlet 15. The integrated air compressor 38 is used to fill compressed air to clean the internal water circuit and can also dry the cleaned endoscope, reducing the cleaning cycle of the endoscope and thus improving the cleaning efficiency. The reverse osmosis filter 39 has a built-in reverse osmosis filter membrane for filtering the water source input through the water inlet pipe 381. The drain pipe 382 is connected to the drain outlet 17 for discharging the waste liquid after disinfection.

[0037] More preferably, it also includes an RFID module 5, which is set on the outer wall of the housing 1. Inserting an RFID card can record the cleaning time, the type and proportion of cleaning liquid used, and facilitate internal traceability.

[0038] More preferably, it also includes a non-contact detection module, which is located on the lower part of the outer wall of the housing 1, and starts the program in a non-contact manner to prevent bacteria generated by contact.

[0039] More preferably, it also includes an automatic tank cover 12, which is connected to the housing 1 by a hinge. When the automatic tank cover 12 is in the closed state, it closes the opening of the first cleaning tank 11. An automatic support 121 is installed on the automatic tank cover 12 to automatically close the first cleaning tank 11 after the endoscope is fixed, so as to prevent liquid splashing during cleaning and avoid interference from external environmental pollution.

[0040] More preferably, multiple liquid inlets 15 are provided on the outer wall of the endoscope connecting frame 14. All multiple liquid inlets 15 are connected to the liquid supply system 3. The multiple liquid inlets 15 face different directions, so that disinfectant liquid can be sprayed from different directions to clean the inside and outside of the endoscope, preventing the leaving of cleaning dead corners.

[0041] The working process of a fully automatic endoscope cleaning machine is as follows:

[0042] The endoscope is placed on the endoscope connecting bracket 14 and fixed. The RFID card is inserted into the RFID module 5. After the control system 2 receives the RFID data, it closes the automatic tank cover 12 and starts the liquid supply system 3. The liquid supply system 3 disinfects the internal water circuit with ozone water, mixes various disinfectant liquids in proportion, and inputs the mixed disinfectant liquid into the liquid inlet 15 through the multi-way solenoid valve 33. The liquid inlet 15 is sprayed onto the endoscope to complete the cleaning and disinfection. After the disinfection is completed, the air compressor 38 outputs air to dry the endoscope. The automatic tank cover 12 is then opened to complete one cleaning procedure.

[0043] Example 2

[0044] This embodiment also discloses a fully automatic endoscope cleaning machine, which includes a second cleaning tank 16. The second cleaning tank 16 is installed on the housing 1, and the structure of the second cleaning tank 16 is the same as that of the first cleaning tank 11. The liquid supply system 3 supplies cleaning liquid to the first cleaning tank 11 and the second cleaning tank 16 respectively through the water supply pipe 37. The water supply pipe 37 is equipped with a valve, which can control the liquid supply to different cleaning tanks, so as to meet the needs of cleaning multiple endoscopes at the same time and improve the cleaning efficiency. The second cleaning tank 16 and the first cleaning tank 11 can be cleaned independently.
