Description

Technical Field

[0001] This utility model relates to the field of endoscope drying technology, and in particular to a drying device for endoscopes. Background Technology

[0002] An endoscope is a detection instrument with an image sensor, optical lens, light source, and mechanical device. Because flexible endoscopes come into direct contact with internal organs and are reusable medical devices, they need to be disinfected and dried after use.

[0003] Drying is an important process to prevent contamination of digestive endoscopes. All tubes and surfaces of the endoscope must be thoroughly dried. Insufficient drying can lead to a contamination rate as high as 80%, and it can also accelerate the formation of biofilms.

[0004] To improve the efficiency of endoscope drying and reduce workload, endoscope drying devices (such as CN220321790U) have been developed. These devices feature a drying chamber with a mounting bracket and a warm air blower inside. Multiple endoscopes are simultaneously mounted on the mounting bracket. In use, after fixing the endoscopes to the bracket, the warm air blower is turned on, allowing air to circulate through the exhaust pipe into the drying chamber, thereby drying the multiple endoscopes on the mounting bracket.

[0005] Existing endoscope drying devices only dry the outer wall of the endoscope with air, without specifically drying the inside of the endoscope lumen. The humid environment makes it easy for biofilm to accumulate inside the endoscope lumen. The formation of biofilm promotes the growth and reproduction of microorganisms, which can easily lead to pipe blockage, corrosion, and infection risks. In addition, existing endoscope drying devices use a warm air blower to blow air directly, which cannot guarantee the cleanliness of the air. It is easy to blow dust and other particles onto the inner and outer surfaces of the endoscope, which not only affects optical performance but also allows dust and other impurities to enter the human body during endoscope use, thus causing infection risks. Furthermore, it is impossible to monitor key factors such as time, pressure, and flow rate during the drying process, making it difficult to trace the drying process. Utility Model Content

[0006] To address the technical problems of existing endoscope drying devices in the background art, which only dry the outer wall of the endoscope with air blowing, without targeted drying treatment inside the endoscope lumen, which easily leads to the proliferation of microorganisms and causes infection risks, and also cannot monitor the drying process in real time, this utility model provides an endoscope drying device.

[0007] The technical solution of this utility model is as follows:

[0008] This utility model provides a drying device for endoscopes, including a cabinet with a drying chamber fixedly mounted on it. Several endoscope trays are slidably installed inside the drying chamber. Several exhaust vents are opened on one side of the drying chamber, and a blowing assembly and several air source interfaces are fixedly mounted on the opposite side of the exhaust vents. The air source interfaces are connected to a clean air source via pipes. The blowing assembly blows air into the drying chamber, and the air source interfaces communicate with the inside of the endoscope. The clean air source ensures that the gas entering the endoscope is clean, preventing dust and other impurities from contaminating the endoscope. The air source interfaces communicate with the inside of the endoscope to dry the cavity. The endoscope trays facilitate the placement of the endoscope. The blowing assembly blows air into the drying chamber to dry the outer surface of the endoscope. The exhaust vents promptly expel moisture generated during the drying process, ensuring the drying effect. This device achieves simultaneous drying of the outer surfaces and inner cavities of multiple endoscopes within the drying chamber, effectively improving the drying efficiency and effect of the endoscope and preventing the problem of microbial growth on the inner and outer surfaces of the endoscope due to incomplete drying.

[0009] Preferably, the cabinet is equipped with a warm air chamber, which is connected to the drying chamber. The blower assembly is fixedly installed in the warm air chamber. The warm air chamber is connected to the outside through a filter assembly. The warm air chamber can heat the gas entering the drying chamber to accelerate the drying speed. The filter assembly can filter the gas entering the warm air chamber from the outside, further ensuring the cleanliness of the gas entering the drying chamber and reducing the impact of dust and other impurities on the endoscope.

[0010] Preferably, the filter assembly includes an air inlet plate, on which a housing is fixedly mounted. Both ends of the housing are covered by cover plates. A first filter unit and a second filter unit are sequentially arranged within the space enclosed by the cover plate, the housing, and the air inlet plate. The first filter unit is close to the air inlet plate, and the housing has an opening on the side close to the second filter unit. The arrangement of multiple filter units allows for multi-stage filtration of the incoming gas. The first filter unit initially filters out larger particulate impurities, and the second filter unit further filters out smaller particles, greatly improving the cleanliness of the gas and providing a cleaner, drier environment for the endoscope.

[0011] Preferably, the blowing assembly includes several drying fans and heating units. The drying fans and heating units are fixedly installed in the warm air chamber. The drying fans are used to blow filtered and heated gas into the drying chamber. The drying fans can quickly blow filtered and heated gas into the drying chamber to improve drying efficiency. The heating units heat the gas to accelerate the evaporation of moisture on the endoscope surface and inside the lumen, thereby achieving efficient drying.

[0012] Preferably, a one-way valve is provided at the gas source interface to prevent gas backflow and ensure that the clean gas source can only enter the endoscope in one direction. This avoids the gas in the dried endoscope lumen from flowing back and introducing impurities or moisture again, thus ensuring the continuity of the drying effect.

[0013] Preferably, there is at least one drying chamber, and several slide rails are fixedly installed at vertical intervals on the inner wall of the drying chamber. The endoscope tray is slidably connected to the slide rails to facilitate the placement and removal of the endoscope tray. The endoscope tray is horizontally placed in the drying chamber and arranged in layers along the vertical direction. The layered endoscope trays can hold multiple endoscopes for drying at the same time, thereby improving the working efficiency of the drying device.

[0014] Preferably, the endoscope tray has several ventilation holes at the bottom and around its sides, which allows the drying gas to better contact the outer surface of the endoscope, ensuring uniform drying, improving the drying effect, and ensuring that the endoscope is effectively dried from all directions.

[0015] Preferably, a monitoring module is installed between the clean gas source and the gas source interface, and a control mechanism is installed on the cabinet. The control mechanism is connected to the monitoring module and can monitor various parameters of the gas between the clean gas source and the gas source interface in real time. The control mechanism adjusts the gas supply according to the monitoring data to ensure the stability and safety of the gas supply and ensure that the drying process of the endoscope is in the optimal state.

[0016] Preferably, the monitoring module includes a micro-mist processor, a solenoid valve, a gas pressure sensor, a gas flow sensor, an electro-proportional valve, and several gas flow switches. The micro-mist processor can process tiny water droplets in the gas to prevent them from causing secondary moisture to the endoscope. The solenoid valve is used to control the gas flow. The gas pressure sensor and the gas flow sensor can monitor the gas pressure and flow in real time. The electro-proportional valve can precisely adjust the gas flow as needed. Each gas flow switch corresponds to a gas source interface and can control the gas flow of each gas source interface individually, realizing independent control of the drying process of different endoscopes.

[0017] Preferably, a high-pressure air gun is installed on the cabinet. The high-pressure air gun is connected to a clean air source. The high-pressure air gun can use the high-pressure gas generated by the clean air source to powerfully blow away hard-to-dry parts or residual impurities, further improving the cleaning and drying effect of the endoscope and ensuring the cleanliness and safety of the endoscope.

[0018] As can be seen from the above technical solutions, the advantages of this utility model are:

[0019] 1. An air source interface and a blower assembly are provided, and several endoscope trays are installed in the drying chamber. The blower assembly is used to blow air into the drying chamber, and the air source interface is used to connect with the inside of the endoscope. This enables simultaneous drying of the outer surfaces and inner cavities of multiple endoscopes in the drying chamber, effectively improving the drying efficiency and effect of the endoscopes and avoiding the problem of microbial growth on the inner and outer surfaces of the endoscopes due to incomplete drying.

[0020] 2. The air source interface is connected to a clean air source through a pipeline, ensuring the cleanliness of the gas entering the endoscope and preventing dust and other impurities from contaminating the endoscope. The warm air chamber is connected to the outside through a filter assembly. The warm air chamber can heat the gas entering the drying chamber to accelerate the drying speed. The filter assembly can filter the gas entering the warm air chamber from the outside, further ensuring the cleanliness of the gas entering the drying chamber and reducing the impact of dust and other impurities on the endoscope.

[0034] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0035] In a typical embodiment of this utility model, such as Figure 1 and Figure 2 As shown, an endoscope drying device is proposed, comprising: a cabinet 1, a drying chamber 3, an endoscope tray 5, and a blowing assembly 7. At least one drying chamber 3 is provided; in this embodiment, two drying chambers 3 are provided, and the two drying chambers 3 are fixedly mounted on the cabinet 1. Several slide rails 6 are fixedly mounted vertically at intervals on the inner wall of the drying chamber 3 to support the endoscope trays 5, allowing the endoscope trays 5 to be horizontally arranged within the drying chamber 3 and vertically layered for the layered placement of multiple endoscopes, such as... Figure 9As shown, the endoscope tray 5 has an open top structure and contains a cavity for holding the endoscope. Several vent holes 32 are provided on the bottom and sides of the endoscope tray 5, allowing gas to pass through for drying the outer surface of the endoscope on the tray 5. A handle 33 is installed on one side of the endoscope tray 5 for easy pulling. Several exhaust holes 8 are provided on one side of the drying chamber 3. A blower assembly 7 is fixedly installed on the side wall opposite the exhaust holes 8, allowing the blower assembly 7 to blow dry air into the drying chamber 3, thereby drying the outer surface of the endoscope on the tray 5. Gas is simultaneously blown dry on endoscopes of different layers through vent 32, and exhaust vent 8 is used to exhaust gas from the drying chamber 3. Several air source interfaces 4 are also fixedly installed vertically on the inner wall of the drying chamber 3. The number of air source interfaces 4 is the same as that of the endoscope tray 5 and they correspond one-to-one. During drying, each cavity on the endoscope is still connected to an irrigation tube (the irrigation tube is connected during the cleaning and disinfection stage). The quick connector of the irrigation tube is connected to the air source interface 4 of the corresponding layer, so that the inner cavity of the endoscope is connected to the clean air source 15 in the cabinet 1 through the air source interface 4, thereby providing a continuous high-pressure airflow for drying the inner cavity.

[0036] Understandably, in practical applications, an anti-drop structure can be installed at the end of the slide rail 6 to prevent the endoscope tray 5 from sliding off automatically, and a transparent opening fan can be installed at the drying chamber 3.

[0037] In this embodiment, the air source interface 4 and the blower assembly 7 enable the simultaneous drying of the outer surfaces and inner cavities of multiple endoscopes in the drying chamber 3, effectively improving the drying efficiency and effect of the endoscopes and avoiding the problem of microbial growth on the inner and outer surfaces of the endoscopes due to incomplete drying.

[0038] The lower part of cabinet 1 is a storage compartment, and the upper surface of the storage compartment is used as a drying table 2 for placing tools, etc. The storage compartment is equipped with a door panel 10, such as... Figure 3 As shown, the clean air source 15 is a medical clean air source bottle. The clean air source 15 is placed in the storage compartment of the cabinet 1. The clean air source 15 delivers clean gas to the air source interface 4 through an air compressor and pipeline for drying the endoscope lumen. The use of the clean air source 15 ensures the cleanliness of the air delivered into the endoscope lumen and avoids the carrying of bacteria and dust.

[0039] It is understood that in other embodiments, the clean air source 15 may be located outside the cabinet 1, and an air source input interface may be provided on the cabinet 1. In this case, the clean air source 15 may be compressed air provided by the hospital's centralized air supply system.

[0040] A control mechanism 13 is fixedly installed on the cabinet 1. The control mechanism 13 includes a human-machine interface and a control circuit board 16. The control circuit board 16 is installed in the storage compartment. A monitoring module 18 is also installed in the storage compartment. The monitoring module 18 is connected to the clean air source 15 and the control circuit board 16. The control mechanism 13 can record and trace the drying time and the gas pressure and flow rate during the process.

[0041] like Figure 7 and Figure 8 As shown, the monitoring module 18 includes a gas flow switch 26, a mist processor 27, a solenoid valve 28, a gas pressure sensor 29, a gas flow sensor 30, and an electro-proportional valve 31. The gas flow switch 26, mist processor 27, solenoid valve 28, gas pressure sensor 29, gas flow sensor 30, and electro-proportional valve 31 are integrated and fixedly mounted on a mounting plate, which is used to fix the module in the storage compartment. There are several gas flow switches 26, and the number of gas flow switches 26 is the same as the number of gas source interfaces 4 and corresponds one-to-one. The monitoring module 18 can monitor key factors such as time, pressure, and flow rate in real time during the drying process, so as to trace the information of the drying process.

[0042] like Figure 10 As shown, the outlet of the clean air source 15 is connected sequentially to a solenoid valve 28, a mist processor 27, a gas pressure sensor 29, an electro-proportional valve 31, a gas flow sensor 30, a gas flow switch 26, and an air source interface 4 via a pipeline. The solenoid valve 28, mist processor 27, gas pressure sensor 29, electro-proportional valve 31, gas flow sensor 30, and gas flow switch 26 are all electrically connected to the control circuit board 16. The solenoid valve 28 controls the on / off state of the air path; the mist processor 27 removes tiny oil mists, water droplets, and solid particles from the gas, making the gas cleaner and drier, protecting subsequent pneumatic components, and extending their service life. To improve the reliability and stability of the system and prevent impurities from entering and causing component wear, blockage, or failure; gas pressure sensor 29 is used to measure the gas pressure value; electro-proportional valve 31 is used to control the gas pressure or flow rate to meet different working requirements; gas flow sensor 30 is used to measure the gas flow rate value; gas flow switch 26 is used to monitor the flow status in the gas pipeline. When the gas flow rate is higher or lower than the set value, it will output an alarm signal or a switch signal. After receiving the signal, the control mechanism 13 will make corresponding instructions, such as opening or closing relevant equipment, adjusting the flow rate, etc., which can prevent system failures or safety problems caused by abnormal flow, and play a protective and control role.

[0043] In this embodiment, a one-way valve is provided at the gas source interface 4 to prevent backflow of gas and avoid contamination of the clean gas source 15 and the pipeline connected to the clean gas source 15.

[0044] like Figure 5 As shown, the blowing assembly 7 includes a drying fan 14 and a heating unit 20. Several drying fans 14 are provided, and the drying fans 14 are axial flow fans. The heating unit 20 is a PTC heating module. The cabinet 1 is provided with a warm air chamber 34. Several through holes are opened on the side wall of the warm air chamber 34. The warm air chamber 34 is connected to the drying chamber 3 through the through holes. The drying fans 14 are fixedly installed at the through hole positions. The warm air chamber 34 is also connected to the outside through the filter assembly 19. The drying fans 14 and the heating unit 20 are both fixedly installed in the warm air chamber 34. The outside air enters the warm air chamber 34 after being filtered by the filter assembly 19. The heating unit 20 heats the air in the warm air chamber 34. The drying fans 14 blow the heated air to the corresponding drying chamber 3 to dry the outer surface of the endoscope in the drying chamber 3 using the hot airflow. The filter assembly 19 is set to ensure the cleanliness of the air entering the warm air chamber.

[0045] It is understandable that the drying fan 14 and the heating unit 20 are both connected to the control mechanism 13 to facilitate rapid control of the blowing and heating operations.

[0046] like Figure 4 and Figure 6 As shown, the filter assembly 19 is detachably installed on the back of the heating chamber 34. The filter assembly 19 includes an air inlet plate 21, a first filter unit 22, a second filter unit 23, a housing 24, and a cover plate 25. The air inlet plate 21 has several through holes for gas passage. The housing 24 is fixedly mounted on the air inlet plate 21 and is placed inside the heating chamber 34. The cover plate 25 is fastened to the upper and lower ends of the housing 24. The cover plate 25, the housing 24, and the air inlet plate 21 enclose a filter chamber. The first filter unit 22 and the second filter unit 23 are sequentially fixedly installed inside the filter chamber. The filter unit 22 is located near the air inlet plate 21. The housing 24 has an open structure on the side near the second filter unit 23. External air enters the warm air chamber 34 sequentially through the air inlet plate 21, the first filter unit 22, and the second filter unit 23 to complete the air filtration and ensure the cleanliness of the air. The first filter unit 22 is a pre-filter, and the second filter unit 23 is a HEPA high-efficiency filter. All mounting surfaces of the filter assembly 19 are equipped with sealing strips to ensure that all air entering the filter chamber is filtered by the first filter unit 22 and the second filter unit 23.

[0047] like Figure 3 As shown, a power supply 17 is also fixedly installed inside the storage compartment of cabinet 1. The power supply 17 is used to provide power support for all working devices; such as Figure 2As shown, a storage box 9 and a bracket for supporting the high-pressure air gun 12 are also fixedly installed on the cabinet 1. The high-pressure air gun 12 is placed on the bracket. The storage box 9 is used to store accessories and other small parts of the endoscope. The high-pressure air gun 12 is connected to the clean air source 15. The high-pressure air gun 12 is used to manually dry the outer surface of the endoscope. The bottom of the cabinet 1 is equipped with casters 11. The casters 11 have self-locking parts to facilitate the movement of the cabinet 1 and fix its position.

[0048] The specific working principle is as follows:

[0049] After cleaning and disinfection, the flexible endoscope is blown with a high-pressure air gun 12 and its surface is wiped with a sterile cloth. The endoscope is then placed in the endoscope tray 5, and the irrigation tubes connecting the various cavities on the endoscope are connected to the corresponding air source interface 4, so that the internal cavity of the endoscope is connected to the clean air source 15. The drying fan 14, heating unit 20, clean air source 15 and monitoring module 18 are controlled by the control mechanism 13. Clean gas is delivered to the inside of the endoscope through the pipeline to dry the inside of the endoscope. At the same time, the heating unit 20 heats the external gas filtered by the filter component 19. The drying fan 14 blows the heated gas into the drying chamber 3 for secondary drying of the outer surface of the endoscope, and at the same time increases the temperature in the drying chamber 3 to assist in the drying of the inside of the endoscope. This achieves simultaneous drying of the inside and outside of the endoscope, effectively improving the drying effect and efficiency.

[0050] It should be noted that before placing the endoscope into the drying chamber 3, the drying fan 14 can be turned on to expel the gas in the drying chamber 3 in advance to ensure the cleanliness of the drying chamber 3; and the high-pressure air gun 12 can also be used to powerfully blow away hard-to-dry parts or residual impurities to further improve the cleaning and drying effect of the endoscope and ensure the cleanliness and safety of the endoscope.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
