[0029] The angle adjustment assembly 9 includes a linkage disk 13 rotatably connected to the top of the disinfection chamber 1, and a linkage arm 15 and a linkage arm 2 151 are respectively provided on the bottom surface of the linkage disk 13 near the side, and the linkage arm 15 and the linkage arm 2 151 are respectively rotatably connected to the bottom surface of the linkage disk 13 through a first connecting rod 26, one end of the linkage arm 2 151 is rotatably connected to the driving cylinder 14, one end of the linkage arm 15 is rotatably connected to the second connecting rod 27, one end of the second connecting rod 27 is rotatably connected to the moving pressure rod 16 docked with the refraction assembly 8, and the bottom centers of the linkage arm 15 and the linkage arm 2 151 are both rotatably connected to the top of the disinfection chamber 1.

[0030] The outer wall of the movable pressure rod 16 is movably sleeved with a pressure rod guide cylinder 17 for guiding it.

[0031] The output end of the driving motor 12 is fixedly connected to the bottom end of the center rod 6 through a reduction device, the bottom surface of the disinfection chamber 1 is fixedly connected to a support leg 4, the control panel 3 is located on one side of the closed door 2, and the ultraviolet lamp tube 7 is fixedly connected to the inner wall of the disinfection chamber 1 through a lamp tube mounting bracket 28.

[0032] The working principle of the medical device disinfection and sterilization processing device is described in detail below.

[0033] like Figure 1-8 As shown, when using, first check whether the appearance of the disinfection chamber 1 is intact. Check whether there are any debris or residual stains from the last use inside the disinfection chamber 1. If there are any, clean them with special tools. Check whether the control panel 3 and the indicator lights on the plasma generator 10 are normal, and whether the nozzle 11 is tightly connected.

[0034] After the inspection is completed, wipe the surface of the placement tray 5 clean and lay a layer of soft and breathable protective pad.

[0035] The medical devices to be sterilized are placed on the corresponding placement tray 5 according to their types and sizes, and the medical devices are placed separately. After the placement is completed, the closed door 2 is closed and ensured to be in a sealed state.

[0036] According to the material characteristics, precision and contamination degree of the medical device, the disinfection parameters are set through the control panel 3. For heavily contaminated metal devices, the irradiation disinfection time of the ultraviolet lamp 7 can be appropriately increased; for precision electronic medical devices, the intensity of the ultraviolet lamp 7 and the output power of the plasma generator 10 are reduced. After the settings are completed, the disinfection and sterilization program is started.

[0037] The ultraviolet lamp 7 is first started to perform preliminary sterilization with ultraviolet rays, and the surface of the instrument is irradiated with a preset angle and intensity. The refraction component 8 and the angle adjustment component 9 start to adjust the deflection angle of the refraction mirror 20 according to the preset of the control panel 3. The driving motor 12 is started synchronously, driving the center rod 6 to rotate slowly, and the center rod 6 drives the placement tray 5 to rotate, so that the instrument placed on the placement tray 5 can be more fully exposed to ultraviolet rays.

[0038] The driving cylinder 14 is started, and through the linkage arm 2 151, the linkage disk 13 is pulled to start rotating counterclockwise, and the linkage disk 13 pulls the first connecting rod 26, and the first connecting rod 26 forms a pushing effect on the second connecting rod 27 with the help of the linkage arm 15. At this time, the second connecting rod 27 will push the movable pressure rod 16 to move it to the position of the receiving rod 18. When the top of the movable pressure rod 16 contacts the top of the receiving rod 18, it will exert pressure on it, pushing the receiving rod 18 to start moving downward, and the receiving rod 18 will push the adjusting push plate 25 during the downward movement, and the adjusting push plate 25 will push the refractor 20 to start deflecting it around the connecting axis with the inner wall of the mounting frame 19, thereby forming a refraction of the light of the ultraviolet lamp 7, and after the movable pressure rod 16 is reset, the receiving rod 18 will move upward under the reset force of the reset spring 23, and the refractor 20 will be reset again under the pull of the adjusting push plate 25 to restore the initial deflection angle. A monitoring component is provided in the disinfection chamber 1 for real-time monitoring of the intensity of ultraviolet rays and the surface temperature of the instrument.

[0039] When the irradiation time of the ultraviolet lamp tube 7 reaches the preset value, the plasma generator 10 is turned on, and the plasma generated by the plasma generator 10 performs secondary enhanced disinfection on the instrument. The plasma is evenly distributed in the chamber, fully contacts the surface of the instrument, and kills residual bacteria, viruses and other microorganisms. The outer wall of the ultraviolet lamp tube 7 is provided with a highly transparent quartz glass lampshade, which can effectively filter out the ultraviolet bands that are harmful to the human body and maximize the transmittance of ultraviolet rays.

[0040] After the disinfection is completed, the closed door 2 is opened, and the medical devices in the disinfection chamber 1 are taken out after wearing sterile gloves, and the devices are placed in a dedicated sterile storage container or transport vehicle for subsequent use or storage.

[0041] Second, as Figure 1-8 As shown, based on Example 1, the present invention provides a technical solution: preferably, a method for disinfecting and sterilizing medical devices, the main steps of the method for disinfecting and sterilizing medical devices are as follows: Step 1: Device preparation; Step 2: Disinfection and sterilization; Step 3: Access and transfer.

[0042] The device preparation in step 1 includes the following steps: A1: First, check whether the appearance of the disinfection chamber 1 is intact. Check whether there is any debris or residual stains from the last use inside the disinfection chamber 1. If there is, clean it with special tools.

[0043] A2: Check whether the indicator lights on the control panel 3 and the plasma generator 10 are normal, and whether the nozzle 11 is tightly connected.

[0044] The disinfection and sterilization in step 2 includes the following steps: B1: After the inspection is completed, wipe the surface of the placement tray 5 clean and lay a layer of soft and breathable protective pad.

[0045] B2: The medical devices to be sterilized are placed on the corresponding placement tray 5 according to their types and sizes, and the medical devices are placed separately. After the placement is completed, the closed door 2 is closed and ensured to be sealed.

[0046] B3: Set the disinfection parameters through the control panel 3 according to the material characteristics, precision and pollution degree of the medical device. For heavily polluted metal devices, the irradiation disinfection time of the ultraviolet lamp 7 can be appropriately increased; for precision electronic medical devices, the intensity of the ultraviolet lamp 7 and the output power of the plasma generator 10 can be reduced. After the settings are completed, start the disinfection and sterilization program.

[0047] B4: The ultraviolet lamp 7 is first started to perform preliminary sterilization with ultraviolet rays, and the surface of the instrument is irradiated with a preset angle and intensity. The refraction component 8 and the angle adjustment component 9 start to adjust the deflection angle of the refraction mirror 20 according to the preset of the control panel 3. The drive motor 12 is started synchronously, driving the center rod 6 to rotate slowly, and the center rod 6 drives the placement tray 5 to rotate, so that the instrument placed on the placement tray 5 can be more fully exposed to ultraviolet rays.

[0048] B5: After the irradiation time of the ultraviolet lamp tube 7 reaches the preset value, the plasma generator 10 is turned on, and the plasma generated by the plasma generator 10 performs secondary enhanced disinfection on the instrument. The plasma is evenly distributed in the chamber and fully contacts the surface of the instrument to kill residual bacteria, viruses and other microorganisms. The outer wall of the ultraviolet lamp tube 7 is provided with a highly transparent quartz glass lampshade, which can effectively filter out the ultraviolet bands that are harmful to the human body and maximize the transmittance of ultraviolet rays.

[0049] The transfer in step 3 includes the following steps: C1: After the disinfection is completed, the closed door 2 is opened, and the medical devices in the disinfection chamber 1 are taken out after wearing sterile gloves, and the devices are placed in a dedicated sterile storage container or transport vehicle for subsequent use or storage.

[0050] C2: After all the instruments are taken out, the interior of the disinfection chamber 1 is cleaned and maintained.

[0051] Beneficial effects: The coordinated use of ultraviolet lamps, plasma generators, drive motors, center rods and placement trays enables the medical devices placed on the placement tray to receive ultraviolet radiation more comprehensively during the rotation process, reducing the existence of blind spots. At the same time, the plasma generated by the plasma generator can perform secondary enhanced disinfection on the devices, thereby improving the disinfection and sterilization effect. The coordinated use of the refraction component and the angle adjustment component enables the device to evenly distribute ultraviolet rays to every corner of the disinfection chamber through reflection and refraction formed by the refractor, further improving the disinfection and sterilization effect. In addition, the deflection angle of the refractor can be adjusted as needed to further reduce the problem of obstruction between devices affecting the sterilization efficiency.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0053] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
