Description

Technical Field

[0001] This invention relates to the field of medical device storage and disinfection technology, and in particular to a medical device storage device with self-disinfection function. Background Technology

[0002] In settings such as medical clinics, dental clinics, and community health service centers, a large number of stainless steel medical instruments (such as tweezers, probes, and scissors) need to be used, disinfected, and stored frequently. The sterility of these instruments is directly related to medical safety and is a core requirement that is of great concern in the field of medical disinfection and storage. Existing medical device sterilization and storage equipment suffers from the following drawbacks: First, the sterilization and storage functions are integrated into the same chamber, making sterilized instruments susceptible to secondary contamination during long-term storage. Furthermore, the sterilization chamber cannot continuously sterilize in batches, resulting in low efficiency and failing to meet the high-frequency, large-volume instrument sterilization and storage needs in clinical settings, contradicting the technical orientation of maintaining efficient aseptic performance. Second, the fixed structure of the instruments prevents switching between "unfolding for sterilization and closing for transport," leading to insufficient exposure of instruments during sterilization, unavoidable sterilization blind spots, large space requirements during transport, and a high risk of instruments falling off. Third, the transport process relies heavily on manual operation with low automation, increasing the workload of medical staff and potentially causing cross-contamination due to human contact, violating the core principle of "aseptic operation and reduced human intervention" in medical settings. Fourth, existing equipment uses a single sterilization method, often employing only ultraviolet or ozone sterilization, making comprehensive, multi-dimensional sterilization difficult. The storage chamber lacks effective antibacterial and drying methods, making sterilized instruments susceptible to moisture and bacterial growth, failing to maintain a long-term aseptic state and falling short of hygiene and protection standards.

[0003] Furthermore, most existing disinfection and storage equipment suffers from problems such as complex structure, cumbersome operation, and large footprint, resulting in poor adaptability and difficulty in meeting the needs of small medical facilities (such as community health service centers and small dental clinics). At the same time, while some equipment achieves separation of disinfection and storage, the transportation process still requires manual assistance, making full automation impossible. This not only leads to low efficiency but also poses a risk of secondary contamination.

[0004] To address the shortcomings of the existing technologies, this invention proposes a medical device storage device with self-disinfection function, which realizes automated linkage of disinfection, transportation, and storage, improves disinfection efficiency and storage safety, reduces manual intervention, avoids secondary pollution, and is suitable for the use needs of medical facilities of different sizes. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a medical device storage device with self-disinfection function.

[0006] The present invention proposes a medical device storage device with self-disinfection function, comprising a vertical box body. The interior of the box body is longitudinally divided into a disinfection chamber and a storage chamber by a vertical partition. The upper part of the vertical partition is provided with a connecting hole connecting the two chambers. The outer sides of the disinfection chamber and the storage chamber are respectively provided with a door.

[0007] The disinfection chamber is equipped with a multi-layer support assembly, a vertical transfer mechanism, and a disinfection module; the storage chamber is equipped with a vertical support mechanism and an antibacterial drying module.

[0008] The vertical transfer mechanism and the vertical support mechanism cooperate with the inclined guide at the through hole to realize the cross-cavity transfer of the support component from the disinfection chamber to the storage chamber. The vertical support mechanism is used to carry the support component after the transfer in layers to realize batch storage.

[0009] Preferably, the multi-layered load-bearing assembly includes multiple sets of combined load-bearing trays, each set of load-bearing trays being formed by two metal mesh plates hinged together by a positioning strip in the middle, with chucks fixedly installed at both ends of the positioning strip;

[0010] The surface of the metal mesh plate is provided with positioning grooves that are adapted to the shape of the stainless steel medical device, and the device is embedded in the outer side of the two metal mesh plates.

[0011] The carrying tray can switch between a flattened state and a closed state. In the flattened state, the two metal mesh panels are coplanar to form a horizontal carrying surface. In the closed state, the two metal mesh panels are folded around the positioning strip towards the center. In the flattened state, the positioning strip limits the two metal mesh panels so that the two metal mesh panels can only be unfolded to 180 degrees and are in a horizontal state.

[0012] The positioning groove is equipped with a locking key to hold the instrument in place, preventing the instrument from falling off when the carrying tray is in a folded state.

[0013] It can switch between flattening and folding the carrying tray. The flattened state ensures that the instruments are fully exposed for disinfection, while the folded state reduces the space occupied and facilitates transportation. The cooperation of the locking key and positioning strip ensures the stability of the instruments and the safety of transportation, avoiding insufficient disinfection or instruments falling off during transportation.

[0014] Preferably, in the disinfection chamber, multiple layers of horizontal support members are symmetrically arranged on the inner side of the vertical partition and the inner side wall opposite to the box body. The horizontal support members are used to support the load-bearing tray in a flattened state.

[0015] The disinfection chamber is equipped with two vertical transfer tracks. Both vertical transfer tracks are installed inside the vertical partition and are located on both sides of the horizontal support. Each vertical transfer track is slidably connected to a movable lifting seat. A main support rod is horizontally fixed on the movable lifting seat. A telescopic rod is connected to the end of the main support rod. A limit baffle is fixed to the end of the telescopic rod.

[0016] A strip guide is rotatably connected to the side of the limiting baffle near the vertical partition. A return spring is fixedly connected to the upper side of the main support rod. The return spring is located below the strip guide. When it is in its naturally extended state, the strip guide and the limiting baffle form an acute angle, which is used to clamp the rollers of the support tray. When the strip guide is squeezed by external force, the return spring is compressed, and the strip guide rotates around the rotation point, forming an obtuse angle with the limiting baffle, which is used to release the rollers.

[0017] The horizontal support can stably support the flattened carrying tray, ensuring the stability of the disinfection process; the vertical transfer track and the mobile lifting seat work together to lift the carrying tray; the linkage design of the strip guide, return spring and limit baffle can accurately realize the locking and releasing of the chuck, the structure is compact and the operation is stable, avoiding loosening or deviation during the transfer process.

[0018] Preferably, the inclined guide is two sets of inclined guide rails, and the two sets of inclined guide rails are respectively connected to the strip guides on the two vertical transfer tracks.

[0019] Each set of inclined guide rails extends at one end to the connecting hole of the disinfection chamber and is at a high position, and at the other end to the interior of the storage chamber and is at a low position, forming a guide structure that slopes downward from the disinfection chamber to the storage chamber.

[0020] Each set of inclined guide rails has a transition slope on the upper side of the end closest to the disinfection chamber, which is used to achieve a smooth connection between the corresponding strip guide and the inclined guide rail, and to avoid jamming of the rollers.

[0021] The inclined structure of the inclined guide rail allows for cross-cavity transfer of the pallet using gravity, eliminating the need for additional power and saving energy. The transition slope effectively prevents jamming when the strip guide component connects with the short rail, ensuring smooth transfer and reducing the probability of equipment failure.

[0022] Preferably, in the storage chamber, two parallel vertical support rails are fixedly installed on the side wall away from the vertical partition, and the vertical support rails are coplanar with the vertical transfer rail and inclined guide rail of the disinfection chamber;

[0023] The vertical bearing mechanism includes multiple sets of symmetrically arranged movable bearing seats. Each set of movable bearing seats consists of two bearing seats that are slidably connected to two vertical bearing rails. Each bearing seat is fixedly installed with an inclined bearing bar. The inclination angle of the inclined bearing bar is consistent with the inclination angle of the inclined guide rail, and it is used to dock with the inclined guide rail and carry the bearing pallet after transfer.

[0024] Multiple sets of mobile support seats are evenly distributed along the vertical support track. In the initial state, they are stored at the top of the storage chamber. After one set of mobile support seats is full of support trays, it moves downward along the vertical support track. The next set of mobile support seats moves downward synchronously to the docking position, realizing multi-layer batch storage.

[0025] The vertical support rail and the inclined guide rail are coplanar to ensure a continuous transfer path. The inclined support bar precisely aligns with the short rail to prevent the support tray from falling off during transfer. The layered design of multiple sets of mobile support seats enables batch storage of instruments and can automatically switch docking positions to improve storage efficiency and save storage space.

[0026] Preferably, the disinfection module includes a UV-C ultraviolet disinfection lamp and an ozone generator, both installed on the inner wall of the disinfection chamber, for comprehensive disinfection of the flattened carrying tray and instruments.

[0027] The antibacterial drying module is a low-temperature hot air circulation device installed on the inner wall of the storage chamber. It is used to periodically deliver low-temperature hot air to the storage chamber to achieve chamber drying and instrument antibacterial properties, maintaining a sterile state.

[0028] The combined UV-C ultraviolet light and ozone disinfection can achieve all-round disinfection of instruments without dead angles, resulting in a more thorough disinfection effect that meets the aseptic requirements of medical scenarios. The low-temperature hot air circulation not only dries the storage chamber but also inhibits bacteria, preventing instruments from getting damp and growing bacteria after disinfection, thus maintaining a sterile state for a long time.

[0029] Preferably, the mobile lifting seat is initially located at the bottom of the vertical transfer track, with the telescopic rod in a retracted state to avoid contact with the rollers on both sides of the lower carrying tray during the lifting process; when the mobile lifting seat rises to the position of the target carrying tray, the telescopic rod extends, and the strip guide and the limiting baffle form an acute angle to lock the rollers, driving the carrying tray to rise and detach from the horizontal support to complete automatic folding, until the strip guide contacts the inclined guide rail.

[0030] The initial design of the mobile lifting platform can prevent collisions with the lower carrying tray during the lifting process, protecting equipment and instruments; the linkage design of automatic folding and precise docking enables seamless connection of the carrying tray from disinfection to transfer, improving transfer efficiency and reducing manual intervention.

[0031] Preferably, a small gap is allowed between the inclined guide rail and the end of the inclined mounting strip aligned with the storage chamber, which does not affect the normal rolling and transfer of the chuck.

[0032] The small gap can prevent collision and wear when the inclined guide rail and the inclined mounting bar are connected, thus extending the service life of the equipment. At the same time, it does not affect the rolling of the chuck, ensuring the stability and smoothness of the transfer process, and taking into account both equipment protection and usage effect.

[0033] Preferably, the chuck is provided with a groove, which is adapted to the upper surface of the strip guide, the inclined guide rail and the inclined mounting bar to prevent the chuck from derailing.

[0034] The matching design of the wheel groove and each guide structure can effectively limit the movement trajectory of the chuck, prevent derailment during the transfer process, further improve the stability and safety of the pallet transfer, and avoid damage or contamination of the equipment due to derailment.

[0035] Preferably, the movement of the mobile support seat on the vertical support track, the sliding of the mobile lifting seat on the vertical transfer track, and the extension and retraction of the telescopic rod are all automatically controlled by a PLC controller, realizing automated transfer, layered storage, and batch disinfection of the support components. PLC automatic control automates the entire process of disinfection, transfer, and storage without manual intervention, reducing the workload of medical staff and avoiding cross-contamination of instruments caused by manual contact.

[0036] The medical device storage and retrieval device with self-disinfection function proposed in this invention has the following beneficial effects:

[0037] 1. Separate design for disinfection and storage: The cabinet is divided into independent disinfection chamber and storage chamber by vertical partitions. The disinfection chamber is responsible for batch compound disinfection, and the storage chamber is responsible for antibacterial and dry storage to avoid secondary contamination of instruments after disinfection. At the same time, the disinfection chamber can continuously disinfect in batches to improve work efficiency.

[0038] 2. The switchable carrying tray consists of two hinged metal mesh plates. When flat, the positioning strip is limited to 180 degrees to ensure that the instruments are fully exposed and in full contact with the ultraviolet rays of the disinfection module, achieving all-round disinfection without any blind spots. When closed, the volume is reduced, making it easy to transport. The locking key in the positioning groove can prevent the instruments from falling off when folded, ensuring safe transport.

[0039] 3. A stable and efficient transfer mechanism, with vertical transfer rails, strip guides, and return springs working together to achieve precise locking and releasing of the chucks. Two sets of inclined guide rails are coplanar with the vertical transfer rails and vertical load-bearing rails, and the transition slope avoids transfer jamming. The chuck groove design prevents derailment, improves transfer stability, and achieves coordinated operation of disinfection, transfer, and storage.

[0040] 4. Automated layered storage: Multiple sets of mobile support seats are distributed in layers along the vertical support track to realize batch layered storage of support trays. The PLC controller controls the movement of the mobile support seats, mobile lifting seats and telescopic rods to achieve full automation, reduce manual labor intensity, avoid human contact contamination, and meet the aseptic operation requirements of medical scenarios.

[0041] 5. Excellent sterility maintenance: The disinfection module uses UV-C ultraviolet light + ozone composite disinfection to ensure thorough disinfection. The low-temperature hot air circulation device in the storage chamber regularly dries and inhibits bacteria, maintaining the sterility of the instruments for a long time and meeting the strict requirements of medical scenarios.

[0042] 6. Strong adaptability: The overall structure is compact and occupies a small area, making it suitable for both large medical institutions and small medical sites, thus solving the problem of poor adaptability of similar equipment under the existing A61L classification.

[0043] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0061] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0062] like Figures 1-8 The medical device storage and retrieval device shown includes a vertical housing 1 made of stainless steel with a rectangular structure for easy placement next to a medical workbench. The interior of the housing 1 is longitudinally divided into a sterilization chamber 101 and a storage chamber 102 by a vertical partition 103. The vertical partition 103 is made of stainless steel and is 5-8 mm thick, ensuring complete isolation between the two chambers and preventing cross-contamination.

[0063] The upper part of the vertical partition 103 has a connecting hole 104 that connects the two chambers. The size of the connecting hole 104 is adapted to the inclined guide 7 to facilitate the cross-chamber transfer of the carrying components. The outer sides of the disinfection chamber 101 and the storage chamber 102 are respectively provided with doors. The doors are made of transparent tempered glass to facilitate observation of the state inside the chamber. A sealing strip is provided between the door and the box body 1 to ensure the airtightness of the chamber. The door of the disinfection chamber 101 is used to replenish the carrying tray 2, and the door of the storage chamber 102 is used to remove the disinfected carrying tray 2. The two doors are set independently and do not interfere with each other, realizing the separation of disinfection, storage and retrieval operations.

[0064] The disinfection chamber 101 is equipped with a multi-layer support assembly, a vertical transfer mechanism 3, and a disinfection module 4. The storage chamber 102 is equipped with a vertical support mechanism 5 and an antibacterial drying module 6. The vertical transfer mechanism 3 and the vertical support mechanism 5 cooperate with the inclined guide 7 at the through hole 104 to realize the cross-cavity transfer of the support assembly from the disinfection chamber 101 to the storage chamber 102. The vertical support mechanism 5 is used to carry the support assembly after the transfer in layers to realize batch storage.

[0065] The multi-layer support assembly includes multiple sets of combined support trays 2. Each support tray 2 is formed by two metal mesh plates 201 hinged together by a positioning strip 202 in the middle. The metal mesh plates 201 are made of 304 stainless steel with uniform mesh openings on the surface to facilitate the penetration of ultraviolet light and ozone, achieving all-round disinfection of instruments. The positioning strip 202 is a stainless steel strip structure with rollers 203 fixedly installed at both ends. The rollers 203 are made of wear-resistant engineering plastic and have a long service life. The surface of the metal mesh plates 201 has positioning grooves 204 that are adapted to the shape of the stainless steel medical instruments. The instruments are embedded in the outer side of the two metal mesh plates 201. The size of the positioning grooves 204 is consistent with the shape of the instruments. The shape of commonly used medical instruments (such as forceps and probes) is matched to ensure stable placement of the instruments; the support tray 2 can switch between a flat and a closed state. In the flat state, the two metal mesh plates 201 are coplanar to form a horizontal support surface, and the positioning strip 202 limits the two metal mesh plates 201 to only unfold to 180 degrees in a horizontal state. The purpose is to allow the instruments to fully contact the ultraviolet light to ensure thorough disinfection without dead corners. In the closed state, the two metal mesh plates 201 are folded downward around the positioning strip 202. The positioning groove 204 is provided with a locking key to hold the instruments in place, preventing the instruments from falling off when the support tray 2 is in the folded state.

[0066] Inside the disinfection chamber 101, multiple layers of horizontal support members 301 are symmetrically arranged on the inner side of the vertical partition 103 and the inner wall opposite to the box body 1. The horizontal support members 301 are stainless steel strip brackets, evenly distributed along the vertical direction, with the spacing adapted to the height of the carrying tray 2, used to support the carrying tray 2 in a flattened state. Two vertical transfer tracks 302 are provided inside the disinfection chamber 101, both installed on the inner side of the vertical partition 103 and located on both sides of the horizontal support members 301. A movable lifting seat 303 is slidably connected to each vertical transfer track 302. A sliding bearing is provided between the movable lifting seat 303 and the vertical transfer track 302 to reduce sliding friction and improve lifting stability. A main support rod 304 is horizontally fixed on the movable lifting seat 303. The main support rod 304 is a stainless steel round rod, with a telescopic rod 305 connected to its end. The telescopic rod 305 is an electric telescopic rod with high telescopic accuracy and limited end fixation. Position baffle 306, made of stainless steel, is used to limit the position of the carrying pallet 2 and prevent it from shifting during transport. A strip guide 307 is rotatably connected to the side of the position baffle 306 near the vertical partition 103. The strip guide 307 is a smooth stainless steel strip structure, facilitating the rolling of the roller 203. A return spring 308 is fixedly connected to the upper side of the main support rod 304, and the other end of the return spring 308 is fixedly connected to the bottom of the strip guide 307. When the return spring 308 is in its naturally extended state, the strip guide 307 and the position baffle 306 form an acute angle (45-70 degrees), which is used to clamp the roller 203 of the carrying pallet 2. When the strip guide 307 is subjected to external force, the return spring 308 is compressed, and the strip guide 307 rotates around the rotation point, forming an obtuse angle (100-120 degrees) with the position baffle 306, which is used to release the roller 203, enabling the loading and unloading of the carrying pallet 2.

[0067] The inclined guide 7 consists of two sets of inclined guide rails 701, which are respectively connected to the strip guides 307 on the two vertical transfer tracks 302. One end of each set of inclined guide rails 701 extends to the through hole 104 of the disinfection chamber 101 and is at a high position, while the other end extends into the storage chamber 102 and is at a low position, forming a guide structure that slopes downward from the disinfection chamber 101 to the storage chamber 102. The inclination angle is 15-20 degrees, which facilitates the sliding transfer of the carrying tray 2 by its own weight. Each set of inclined guide rails 701 has a transition slope on the upper side of the end near the disinfection chamber 101. The transition slope is an arc-shaped slope, which is used to achieve a smooth connection between the corresponding strip guide 307 and the inclined guide rail 701 and avoid jamming of the roller 203.

[0068] Inside the storage chamber 102, two parallel vertical support rails 501 are fixedly installed on the side wall away from the vertical partition 103. The vertical support rails 501 are coplanar with the vertical transfer rail 302 and the inclined guide rail 701 of the disinfection chamber 101 to ensure a continuous transfer path. The vertical support mechanism 5 includes multiple sets of symmetrically arranged movable support seats. Each set of movable support seats consists of two support seats 502 that are slidably connected to the two vertical support rails 501. Each support seat 502 is fixedly equipped with an inclined support bar 503. The inclination angle of the inclined support bar 503 is the same as the inclination angle of the inclined guide rail 701. It is used to dock with the inclined guide rail 701 and carry the transported pallet 2. The multiple sets of movable support seats are evenly distributed along the vertical support rails 501. In the initial state, they are stored at the top of the storage chamber 102. After one set of movable support seats is full of the transport pallet 2, it moves downward along the vertical support rails 501. The next set of movable support seats moves downward synchronously to the docking position to realize the layered batch storage of the transport pallet 2.

[0069] The disinfection module 4 includes an ultraviolet disinfection lamp 401 and an ozone generator 402, both installed on the inner wall of the disinfection chamber 101. The ultraviolet disinfection lamp 401 is a UV-C ultraviolet lamp with a wavelength of 254nm, evenly distributed on the top and side walls of the disinfection chamber 101, used to disinfect the flattened support tray 2 and instruments with ultraviolet light. The ozone generator 402 is installed at the bottom of the disinfection chamber 101 and can generate ozone at a concentration of 0.3-0.5mg / m³, which, together with the ultraviolet disinfection lamp 401, forms a composite disinfection to achieve all-round disinfection of instruments. The disinfection time can be set by the PLC controller. The antibacterial drying module 6 is a low-temperature hot air circulation device installed on the inner wall of the storage chamber 102. The hot air temperature is controlled at 40-50℃ to avoid high temperature damage to instruments. It is used to periodically deliver low-temperature hot air to the storage chamber 102 to achieve chamber drying and instrument antibacterial effect, maintaining the sterile state of the instruments. The circulation cycle can be set by the PLC controller.

[0070] Initially, the movable lifting platform 303 is located at the bottom of the vertical transfer track 302, and the telescopic rod 305 is retracted to avoid contact with the chucks 203 on both sides of the lower carrying pallet 2 during lifting. When the movable lifting platform 303 rises to a position below the uppermost target carrying pallet 2, the telescopic rod 305 extends and moves upward. The strip guide 307 and the limiting baffle 306 form an acute angle to position the chucks 203. The movable lifting platform 303 continues to rise, causing the carrying pallet 2 to detach from the horizontal support 30. 1. Under the action of gravity, the carrying tray 2 folds around the positioning strip 202 towards the center, and the locking key locks the instrument to prevent it from falling off; the moving lifting seat 303 continues to rise to the docking position with the inclined guide rail 701. The strip guide 307 is squeezed by the inclined guide rail 701, the return spring 308 is compressed, the strip guide 307 rotates and tilts to release the locking wheel 203, and the carrying tray 2 slides along the inclined guide rail 701 by its own gravity, realizing the transfer from the disinfection chamber 101 to the storage chamber 102.

[0071] A small gap (0.5-1mm) is allowed between the inclined guide rail 701 and the end of the inclined mounting bar 503 in the storage chamber 102. This gap does not affect the rolling and transfer operation of the roller 203, and at the same time can avoid collision and wear when the two are connected, thus extending the service life of the equipment.

[0072] The chuck 203 has a groove, the width of which is adapted to the width of the upper surface of the strip guide 307, the inclined guide rail 701 and the inclined mounting bar 503, in order to hold the chuck 203 in place and prevent the carrying pallet 2 from derailing during transport, thus ensuring stable transport.

[0073] The movement of the mobile support seat on the vertical support rail 501, the sliding of the mobile lifting seat 303 on the vertical transfer rail 302, and the extension and retraction of the telescopic rod 305 are all automatically controlled by a PLC controller. The PLC controller is installed on the outside of the housing 1 and has an operation panel. It can set parameters such as disinfection time, transfer speed, and hot air circulation cycle to realize automated transfer, layered storage, and batch disinfection of the support components without manual intervention.

[0074] The specific working process in this embodiment is as follows:

[0075] 1. Instrument Placement and Disinfection: Open the door of the disinfection chamber 101, flatten the support tray 2, insert the stainless steel medical instruments into the positioning groove 204 of the metal mesh plate 201, and secure the instruments with the locking key. Place each support tray 2 on the horizontal support 301 of each layer and close the door. Start the disinfection module 4 through the PLC controller. The ultraviolet disinfection lamp 401 and the ozone generator 402 work simultaneously to perform all-round composite disinfection of the instruments. After disinfection is completed, the disinfection module 4 automatically shuts down.

[0076] 2. Automated Transfer: After disinfection, the PLC controller controls the mobile lifting seat 303 to rise along the vertical transfer track 302 to a position below the top target carrying tray 2. The telescopic rod 305 extends, and the acute angle formed by the strip guide 307 and the limiting baffle 306 clamps the positioning rollers 203 on both sides. The mobile lifting seat 303 rises, causing the carrying tray 2 to disengage from the horizontal support 301. During the rise, the carrying tray 2 automatically folds. The mobile lifting seat 303 continues to rise to the docking position with the inclined guide rail 701. After being squeezed, the strip guide 307 tilts and releases the rollers 203. At the same time, the carrying seat 502 stored at the bottom of the storage chamber 102 moves its inclined carrying strip 503 downward to dock with the inclined guide rail 701. At this time, the carrying tray 2 slides along the inclined guide rail 701 by its own weight and enters the storage chamber 102.

[0077] 3. Layered storage: The carrier tray 2 slides along the inclined guide rail 701 onto the inclined mounting strip 503 of the storage chamber 102 to complete the transfer; the PLC controller controls the group of mobile carrier seats to move downward along the vertical carrier rail 501, and the next group of mobile carrier seats moves synchronously to the docking position to prepare to receive the next carrier tray 2, realizing batch layered storage; the antibacterial drying module 6 is started periodically to deliver low-temperature hot air to the storage chamber 102 to maintain the chamber's dryness and antibacterial properties.

[0078] 4. Instrument retrieval: Open the door of storage chamber 102, take out the carrying tray 2 from the inclined mounting strip 503, flatten the carrying tray 2 (positioning strip 202 is limited to 180 degrees), release the lock, and you can take out the sterilized instrument and close the door.
