Description

Technical Field

[0001] This invention relates to the field of medical nursing disinfection technology, and more specifically, to a disinfection device for nursing medical equipment. Background Technology

[0002] Nursing medical instruments refer to the instruments, equipment, and consumables (such as syringes, scalpels, forceps, catheters, dressings, etc.) used by medical personnel during diagnosis, treatment, nursing, or surgery. Because these instruments come into direct contact with the patient's skin, mucous membranes, or bodily fluids, they may carry pathogens that could lead to cross-infection or disease transmission. Therefore, strict disinfection or sterilization is essential to completely kill or remove bacteria, viruses, and other microorganisms from the instruments, ensuring the safety of medical procedures and the health of the patient.

[0003] In the sterilization process of reusable nursing medical equipment, water washing is usually performed first, followed by surface sterilization using ultraviolet (UV) irradiation. However, during static UV sterilization, due to the fixed placement of the instruments, some areas may be blocked by neighboring instruments, preventing the UV light from evenly covering all surfaces. This creates sterilization blind spots in the shaded areas, ultimately affecting the overall sterilization effect.

[0004] For example, the Chinese utility model patent (application number: 202322836703.5) discloses a "disinfection device for clinical medical and nursing utensils," the description of which states: This utility model discloses a disinfection device for clinical medical and nursing utensils, including a drying and disinfection mechanism and a cleaning mechanism. Both the drying and disinfection mechanism and the cleaning mechanism are installed inside a housing, with the drying and disinfection mechanism above the cleaning mechanism. A threaded rod is installed from top to bottom at the center of the housing. A horizontal plate is installed between the drying and disinfection mechanism and the cleaning mechanism, and the center of the horizontal plate is a hollow structure. An inlet is installed on the top of the cleaning mechanism housing, and an outlet is connected to the bottom of the cleaning mechanism housing. This disinfection device uses a sliding rod to move a sieve plate upward into the drying and disinfection mechanism, where the sieve plate filters the disinfectant water. A heating tube heats the internal air, and a second rotating motor is started to drive a rotating rod to rotate. The rotating rod drives a fan to rotate synchronously, and hot air circulates through the through-hole into the center of the drying and disinfection mechanism, increasing air circulation and further improving drying efficiency. This integrates the cleaning and drying processes, avoiding manual operation. However, the above patent still has shortcomings in practical use.

[0005] Based on this, the present invention discloses a sterilization device for nursing medical equipment. Summary of the Invention

[0006] To address the problem mentioned in the background art that static ultraviolet irradiation in the disinfection process of nursing instruments creates shadowed areas due to instrument obstruction, leading to incomplete disinfection, this invention provides a disinfection device for nursing medical instruments. The device includes a housing, an upper cover plate fixedly connected to the upper part of the inner wall of the housing, and a lower cover plate fixedly connected to the lower part of the inner wall of the housing. A plurality of fixed brackets are evenly distributed and fixedly connected on both sides between the upper and lower cover plates. Ultraviolet lamps are installed between the fixed brackets.

Several elastic clips are fixedly connected to the upper surface of the receiving plate evenly distributed. An arc-shaped transparent cover is fixedly connected between the upper cover plate and the lower cover plate. A flipping assembly is provided on the outer wall of the side shaft.

[0007] As a further improvement to this technical solution, a positioning gear is fixedly connected to the top of the fixed cylinder through the upper cover plate, an auxiliary gear is meshed with the outer wall of the positioning gear, a motor is fixedly connected to the upper surface of the auxiliary gear, the motor is fixedly installed on the upper inner wall of the outer shell, and a water-draining component is provided below the fixed cylinder.

[0008] As a further improvement to this technical solution, the flipping assembly includes a gear disk located below the inner ring of the ratchet ring, a side gear fixedly connected to the outer wall of the side shaft, the gear disk and the side gear meshing together, an auxiliary shaft fixedly connected to the end of the frame plate away from the side shaft, and several arc-shaped groove plates fixedly connected in a straight line evenly distributed on the outer wall of the arc-shaped transparent cover, and several elastic ratchet teeth fixedly connected in a straight line evenly distributed on the inner side wall of the arc-shaped groove plates, the arc-shaped groove plates being movably connected to the auxiliary shaft.

[0009] As a further improvement to this technical solution, a conical cover is fixedly connected above the gear disk, a grooved ring is fixedly connected above the conical cover, a roller is movably connected above the grooved ring, and the outer wall of the roller is fixedly installed on the outer wall of the side shaft.

[0010] As a further improvement to this technical solution, two protective arc plates are symmetrically and evenly distributed and fixedly connected between the upper cover plate and the lower cover plate, and several right-angle mirror panels are circumferentially and evenly distributed and fixedly connected to the side of the protective arc plate near the ultraviolet lamp tube.

[0011] As a further improvement to this technical solution, the protective arc plate has several heat sinks evenly distributed and fixedly connected on the side away from the ultraviolet lamp tube, and side frames are fixedly connected to both sides of the outer shell, with inclined groove plates fixedly connected to the inner wall of the side frames.

[0012] As a further improvement to this technical solution, the draining assembly includes a conical cover movably installed below the fixed cylinder. Several supporting ribs are fixedly connected to the bottom of the conical cover in a circumferentially evenly distributed manner. The upper ends of the several supporting ribs are fixedly installed at the bottom of the lower cover plate. Several holes are evenly distributed on the surface of the conical cover, and several through holes are evenly distributed on the surface of the receiving plate.

[0013] As a further improvement to this technical solution, two ribs are fixedly connected in a symmetrical and uniform manner on the lower part of the inner wall of the outer shell, and an auxiliary plate is movably connected above the two ribs. A collection tray is fixedly connected above the auxiliary plate, and the collection tray is located below the conical cover.

[0014] As a further improvement to this technical solution, one end of the auxiliary plate is fixedly connected to a positioning plate through the outer shell, and a handle groove is provided on the lower front side of the outer shell, with the handle groove located below the positioning plate.

[0015] As a further improvement to this technical solution, two hinges are provided on one side of the front of the outer shell, and cabinet doors are provided at the other end of the two hinges. Support legs are fixedly connected in a rectangular and evenly distributed manner at the bottom of the outer shell, and bases are fixedly connected to the bottom of the support legs.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this kind of medical device disinfection device, the medical devices that have been cleaned are rotated. As they rotate continuously, the medical devices are irradiated with ultraviolet light between ultraviolet lamps on both sides for disinfection. This changes the position of the medical devices to prevent the ultraviolet light from not reaching the blind spots, and allows them to come into contact with the ultraviolet light in a rotating manner, thereby improving the efficiency of disinfection.

[0017] 2. In this medical device for nursing care, a gear disc rotates below a side gear, causing the side gear to mesh and rotate, which in turn drives a receiving plate to flip around a side shaft. This causes the medical devices on the surface of the receiving plate to continuously flip around the side shaft, thus performing a dynamic irradiation operation of flipping up and down during the ultraviolet sterilization process. This reduces the ultraviolet irradiation dead angles in the static sterilization process, thereby enabling the medical devices to be flipped and disinfected by ultraviolet irradiation in a dynamic flipping manner, thus achieving comprehensive ultraviolet disinfection of medical devices.

[0018] 3. In this medical device for nursing care, the motor rotates in the opposite direction, and with the cooperation of the auxiliary gear and the positioning gear, the fixed cylinder is driven to rotate within the outer shell by the receiving plate connected to the side shaft. The water stains on the medical devices are detached by the centrifugal force of rotation and come into contact with the arc-shaped transparent cover. As they accumulate, they form a water flow that flows into the conical cover, passes through the holes, and flows into the collection tray. Thus, after the medical devices are cleaned, the centrifugal force of rotation can be used to clean the water stains attached to the outer wall of the medical devices, thereby improving the efficiency of medical device disinfection and cleaning.

[0019] 4. In this kind of medical device for nursing care, during the rotation process, the frame plate on the outer wall of the receiving plate slides in the arc-shaped groove plate by the auxiliary shaft, which cooperates with the rotation of the receiving plate on the outer wall of the fixed cylinder. During the flipping process, the outer wall of the receiving plate rotates by the auxiliary shaft, and the arc-shaped groove plate provides limiting support for the auxiliary shaft, thereby enabling it to flexibly switch between the sliding structure and the rotating shaft structure, improving the efficiency of medical device disinfection.

[0020] 5. In this medical device for nursing care, during rotation, the receiving plate, driven by the fixed cylinder, comes into contact with the ultraviolet light generated after the ultraviolet lamp is turned on, thus achieving rotational ultraviolet disinfection of the medical device. During the dehydration process, the receiving plate connected to the side shaft of the fixed cylinder rotates within the outer shell, and the water stains on the medical device are detached by the centrifugal force of rotation and come into contact with the arc-shaped transparent cover. As they accumulate, they form a water flow, thus enabling flexible switching between the rotational disinfection structure and the centrifugal dehydration structure, improving the efficiency of medical device disinfection.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As described in the background art, the disinfection process for reusable nursing medical equipment typically involves initial water washing followed by surface sterilization using ultraviolet (UV) irradiation. However, during static UV disinfection, due to the fixed placement of the instruments, some areas may be blocked by neighboring instruments, preventing the UV light from evenly covering all surfaces. This creates blind spots in the shaded areas, ultimately affecting the overall sterilization effect.

[0025] Example 1, please refer to Figures 1-11 A sterilization device for nursing medical devices includes a housing 1. An upper cover plate 9 is fixedly connected to the upper part of the inner wall of the housing 1, and a lower cover plate 10 is fixedly connected to the lower part of the inner wall of the housing 1. Several fixing brackets 11 are evenly distributed and fixedly connected on both sides between the upper cover plate 9 and the lower cover plate 10. Ultraviolet lamps 12 are installed between the fixing brackets 11. A rotating assembly 6 is located above the upper cover plate 9. A fixing cylinder 605 is rotatably connected to the middle of the upper cover plate 9. Several fixing brackets 605 are evenly distributed and fixedly connected to the outer wall of the fixing cylinder 605. A ratchet ring 614 is provided. A sleeve 606 is fixedly connected to the upper part of the outer ring of the ratchet ring 614. Several bearing rings 612 are fixedly connected to the outer wall of the sleeve 606 in a circumferentially evenly distributed manner. A side shaft 607 is fixedly connected to the inner ring of the bearing ring 612. A frame plate 610 is fixedly connected to the end of the side shaft 607 away from the sleeve 606. A receiving plate 613 is fixedly connected to the middle of the inner wall of the frame plate 610. Several elastic clips 611 are fixedly connected to the upper surface of the receiving plate 613 in a uniformly distributed manner. The upper cover plate 9 and the lower cover plate 9 are also provided. An arc-shaped transparent cover 604 is fixedly connected to the middle of the plate 10. A flipping component 7 is provided on the outer wall of the side shaft 607. The starter motor 603 rotates in the reverse direction. Under the cooperation of the positioning gear 601 and the auxiliary gear 602, the fixed cylinder 605 is driven to rotate in the forward direction. Under the unidirectional rotation of the ratchet ring 614, the ratchet ring 614 rotates in the forward direction under the connection of the fixed cylinder 605 and is in a locked state. This causes the sleeve 606 to rotate with the fixed cylinder 605. At the same time, the gear disk 608 connected to the ratchet ring 614 rotates as well. Then the side shaft 607 drives the receiving plate 613 to rotate between the two arc-shaped transparent covers 604. The cleaned medical instruments are installed on the elastic clamp 611 on the upper surface of the receiving plate 613. With continuous rotation, the medical instruments clamped on the surface of the receiving plate 613 are irradiated and disinfected between the ultraviolet lamps on both sides, reducing the shadows cast on the objects when they are stationary, which would affect the effect of ultraviolet disinfection.

[0026] The ratchet ring is an existing technology, including an inner ratchet ring and an outer ratchet ring. The two are engaged by an axial pawl and a ratchet groove to form a whole, ensuring that the inner ratchet ring and the outer ratchet ring are properly engaged when the fixed cylinder 605 rotates in the forward direction. The device rotates to carry the cleaned medical instruments. As it rotates, the instruments are irradiated with ultraviolet light between the ultraviolet lamps 12 on both sides for disinfection. This changes the position of the medical instruments to prevent the ultraviolet light from missing any blind spots, and allows them to come into contact with the ultraviolet light through rotation, thus improving the efficiency of disinfection.

[0027] Furthermore, such as Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, a positioning gear 601 is fixedly connected to the upper cover plate 9 through the top of the fixed cylinder 605. An auxiliary gear 602 is meshed with the outer wall of the positioning gear 601. A motor 603 is fixedly connected to the upper surface of the auxiliary gear 602. The motor 603 is fixedly installed on the upper inner wall of the outer casing 1. A drain assembly 8 is provided below the fixed cylinder 605. The auxiliary gear 602 is driven to rotate by the motor 603, and the positioning gear 601 meshing with it rotates accordingly, thereby providing power for the rotation of the fixed cylinder 605.

[0028] Example 2 further optimizes the sterilization device for nursing medical equipment provided in the example, specifically, as follows: Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the flipping assembly 7 includes a gear disk 608 located below the inner ring of the ratchet ring 614. A side gear 701 is fixedly connected to the outer wall of the side shaft 607, and the gear disk 608 and the side gear 701 are meshed together. An auxiliary shaft 705 is fixedly connected to the end of the frame plate 610 away from the side shaft 607. Several arc-shaped groove plates 704 are fixedly connected to the outer wall of the arc-shaped transparent cover 604 in a straight line. Several elastic ratchet teeth 711 are fixedly connected to the inner side wall of the arc-shaped groove plates 704 in a straight line. The auxiliary shaft 705 connected to the frame plate 610 rotates in the arc-shaped groove plates 704, providing a support point for the flipping of the receiving plate 613. The arc-shaped groove plates 704 and the auxiliary shaft 705 are movably connected. During the rotation process, after a period of rotation and disinfection, the motor 603 is started to rotate in the forward direction, and the positioning gear 601 and the auxiliary gear 705 are then engaged. With the cooperation of 2, the fixed cylinder 605 is driven to rotate in the opposite direction. Under the unidirectional rotation of the ratchet ring 614, the ratchet ring 614 is in the unlocked state under the reverse rotation driven by the connection of the fixed cylinder 605 and the sleeve 606. At this time, the sleeve 606 connected to the outer ring of the ratchet ring 614 will not rotate. The gear disk 608 driven in the opposite direction by the fixed cylinder 605 drives the side gear 701 to rotate. The auxiliary shaft 705 connected to the other side of the receiving plate 613 slides in the opposite direction in the arc-shaped groove plate 704. It is limited and stops sliding when it hits the elastic ratchet 711. With the rotation of the side gear 701, the receiving plate 613 is flipped with the side shaft 607 to irradiate and disinfect the other side of the medical device. After the flipping is completed, the motor 603 rotates in the forward direction to continue the rotation disinfection.

[0029] The gear disk 608 rotates below the side gear 701, causing the side gear 701 to mesh and rotate, which in turn drives the receiving plate 613 to rotate around the side shaft 607. This causes the medical instruments on the surface of the receiving plate 613 to rotate continuously around the side shaft 607. This dynamic irradiation operation of rotating up and down during the ultraviolet sterilization process reduces the ultraviolet irradiation dead angles in the static sterilization process. Thus, the medical instruments can be rotated and disinfected by ultraviolet irradiation in a dynamic rotating manner, thereby achieving comprehensive ultraviolet disinfection of medical instruments.

[0030] Furthermore, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a conical cover 609 is fixedly connected above the gear disk 608, a grooved ring 703 is fixedly connected above the conical cover 609, and a roller 702 is movably connected above the grooved ring 703. The outer wall of the roller 702 is fixedly installed on the outer wall of the side shaft 607. The roller 702 connected to the side shaft 607 rolls on the grooved ring 703 above the conical cover 609 to improve the stability of the receiving plate 613 during the flipping process.

[0031] Furthermore, such as Figure 3 and Figure 4 As shown, two protective arc plates 706 are symmetrically and evenly distributed and fixedly connected between the upper cover plate 9 and the lower cover plate 10. Several right-angle mirror panels 710 are evenly distributed and fixedly connected on the side of the protective arc plate 706 near the ultraviolet lamp tube 12. The right-angle mirror panels 710 installed on the protective arc plate 706 reflect the light emitted by the ultraviolet lamp tube 12, thereby improving the efficiency of ultraviolet irradiation disinfection.

[0032] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, a number of heat sinks 707 are evenly distributed and fixedly connected to the protective arc plate 706 on the side away from the ultraviolet lamp tube 12. Side frames 708 are fixedly connected to both sides of the outer shell 1. Inclined groove plates 709 are fixedly connected to the inner wall of the side frames 708. The heat sinks 707 installed on the protective arc plate 706 absorb the heat generated by the ultraviolet lamp tube 12 during operation. The airflow entering the outer shell 1 through the inclined groove plate 709 comes into contact with the heat sinks 707, thereby ensuring that the ultraviolet lamp tube 12 can work for a long time.

[0033] Example 3 further optimizes the sterilization device for nursing medical equipment provided in the example, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the drain assembly 8 includes a conical cover 806 movably installed below the fixed cylinder 605. Several supporting ribs 808 are evenly distributed and fixedly connected to the bottom of the conical cover 806. The upper ends of the supporting ribs 808 are fixedly installed at the bottom of the lower cover plate 10. Several holes 807 are evenly distributed on the surface of the conical cover 806, and several through holes 809 are evenly distributed on the surface of the receiving plate 613. The cleaned medical instruments are pressed and placed into the elastic clips 611 on the surface of the receiving plate 613. After completion, the cabinet door 3 is closed, and the motor 603 is started to rotate in the reverse direction. Under the cooperation of the positioning gear 601 and the auxiliary gear 602, the fixed cylinder 605 is driven to rotate in the forward direction. Under the unidirectional rotation of the ratchet ring 614, the ratchet ring 614 is connected to the fixed cylinder 605... Driven by the rotating mechanism, and in a locked state, the sleeve 606 rotates with the fixed sleeve 605. At the same time, the gear disc 608 connected to the ratchet ring 614 rotates as well. Then, the side shaft 607 drives the receiving plate 613 to rotate within the two arc-shaped transparent covers 604. Subsequently, the receiving plate 613 connected to the side shaft 607 on the outer wall of the fixed sleeve 605 rotates within the two arc-shaped transparent covers 604. Water stains on the medical instruments are detached by the centrifugal force of the rotation and come into contact with the arc-shaped transparent covers 604. As they accumulate, they form a water flow that flows into the conical cover, passes through the hole 807, and flows into the collection tray 805. After a certain amount is collected, the operator uses their hand to reach through the handle groove 804 and contact the positioning plate 803 to remove the collection tray 805 from the outer shell 1.

[0034] By rotating the motor 603 in the reverse direction, and with the cooperation of the auxiliary gear 602 and the positioning gear 601, the fixed cylinder 605 is driven to rotate within the housing 1 via the receiving plate 613 connected to the side shaft 607. The water stains on the medical instruments are then removed by the centrifugal force of the rotation and come into contact with the arc-shaped transparent cover 604. As the water accumulates, it forms a flow that flows into the conical cover, passes through the holes 807, and flows into the collection tray 805. Thus, after the medical instruments are cleaned, the centrifugal force of the rotation can be used to remove the water stains adhering to the outer wall of the medical instruments, thereby improving the efficiency of disinfection and cleaning of the medical instruments.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, two ribs 801 are symmetrically and evenly distributed and fixedly connected to the lower part of the inner wall of the outer shell 1. An auxiliary plate 802 is movably connected above the two ribs 801. A collection tray 805 is fixedly connected above the auxiliary plate 802, and the collection tray 805 is located below the conical cover 806. The collection tray 805 for collecting water stains is supported by the two ribs 801.

[0036] Furthermore, such as Figure 1 and Figure 2As shown, one end of the auxiliary plate 802 passes through the outer shell 1 and is fixedly connected to the positioning plate 803. The lower front of the outer shell 1 is provided with a handle groove 804, and the handle groove 804 is located below the positioning plate 803. The operator can use their hand to pass through the handle groove 804 to contact the positioning plate 803, thereby causing the collection tray 805 above the auxiliary plate 802 to detach from the outer shell 1.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, there are two hinges 2 on one side of the front of the outer shell 1, and a cabinet door 3 at the other end of the two hinges 2. The opening and closing of the cabinet door 3 facilitates the retrieval and placement of medical instruments to be sterilized in the equipment. The bottom of the outer shell 1 is uniformly distributed with support legs 4, and the bottom of the support legs 4 is fixedly connected with a base 5. The base 5 installed on the support legs 4 provides stable support for the overall structure.

[0038] The process of using the sterilization device for nursing medical devices provided by this invention is as follows: The staff opens the cabinet door 3 using hinge 2, and then presses the cleaned medical instruments into the elastic clip 611 of the receiving plate 613. Water droplets on the surface of the medical instruments pass through the through hole 809 in the receiving plate 613 and fall into the conical cover 806. They then pass through the hole 807 in the conical cover 806 and fall into the collection tray 805 for collection and processing. Water stain removal: Starting the motor 603 causes it to rotate in the reverse direction. With the cooperation of the positioning gear 601 and the auxiliary gear 602, the fixed cylinder 605 rotates in the forward direction. Under the unidirectional rotation of the ratchet ring 614, which is connected to the fixed cylinder 605, the ratchet ring 614 rotates in the forward direction and is in a locked state. This causes the sleeve 606 to rotate with the fixed cylinder 605. Simultaneously, the gear disc 608 connected to the ratchet ring 614 rotates as well. Then, the side shaft 607 drives the receiving plate 613 through the two arc-shaped transparent covers. Rotating within 604, the receiving plate 613, connected by the side shaft 607 to the outer wall of the fixed cylinder 605, rotates within the two arc-shaped transparent covers 604. Water stains from the medical instruments are detached by the centrifugal force of the rotation and come into contact with the arc-shaped transparent covers 604. As they accumulate, they form a water flow that flows into the conical cover, passes through the hole 807, and flows into the collection tray 805. Once a certain amount has been collected, the staff can use their hands to reach through the handle groove 804 and contact the positioning plate 803 to remove the collection tray 805 from the outer shell 1. Disinfection by rotation: Restarting motor 603 to rotate in the reverse direction causes the fixed cylinder 605 to rotate forward under the cooperation of positioning gear 601 and auxiliary gear 602. With the unidirectional rotation of ratchet ring 614, which is connected to the fixed cylinder 605 and rotates forward while locked, sleeve 606 rotates with the fixed cylinder 605. Simultaneously, gear disc 608 connected to ratchet ring 614 rotates as well. Then, side shaft 607 drives receiving plate 613 to rotate within the two arc-shaped transparent covers 604. Meanwhile, auxiliary shaft 705 connected to the other side of receiving plate 613 slides forward within arc-shaped groove plate 704, impacting the elastic ratchet 7. 11. Pressing is performed and sliding continues. Then, the side shaft 607 drives the receiving plate 613 to rotate between the two arc-shaped transparent covers 604. The cleaned medical instruments are then installed on the elastic clamp 611 on the upper surface of the receiving plate 613. As it rotates continuously, the ultraviolet lamp tube 12 is turned on. The light passes through the arc-shaped transparent cover 604, and the lamp tube between the ultraviolet lamp tube 12 and the protective arc plate 706 shines on the right-angle mirror panel 710 for reflection, thereby concentrating the light. At this time, the medical instruments clamped on the surface of the receiving plate 613 are irradiated and disinfected between the ultraviolet lamp tubes on both sides, reducing the shadows generated by the irradiated objects in a stationary state, which would affect the effect of ultraviolet disinfection. Disinfection by flipping: Starting the motor 603 causes it to rotate forward. With the cooperation of the positioning gear 601 and the auxiliary gear 602, the fixed cylinder 605 rotates in the opposite direction. Under the unidirectional rotation of the ratchet ring 614, the ratchet ring 614, driven by the connection of the fixed cylinder 605 and the sleeve 606, rotates in the opposite direction and is in the unlocked state. At this time, the sleeve 606 connected to the outer ring of the ratchet ring 614 will not rotate. The gear disc 608, driven in the opposite direction by the fixed cylinder 605, drives the side gear 701 to rotate. Meanwhile, the auxiliary shaft 705 connected to the other side of the receiving plate 613 slides in the opposite direction within the arc-shaped groove plate 704, impacting... When the elastic ratchet 711 is struck, it is stopped from sliding and rotates in conjunction with the side gear 701. The side gear 701 connected to the side shaft 607 on the outer wall of the sleeve 606 meshes and rotates on the upper surface of the gear disk 608, causing the receiving plate 613 to flip around the side shaft 607. During the flipping process, the roller 702 connected to the outer wall of the side shaft 607 rolls on the groove ring 703 above the conical cover 609, stabilizing the flipping process of the receiving plate 613 around the side shaft 607, so as to irradiate and disinfect the other side of the medical device. After the flipping is completed, the motor 603 rotates in the forward direction to continue the rotational disinfection.
