Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a medical device storage cabinet. Background Technology
[0002] In modern medical diagnosis and treatment, the efficacy and safety of numerous medical devices and consumables directly depend on their storage environment, especially temperature. Traditional storage methods are no longer sufficient to meet these stringent requirements. Many drugs (such as insulin and certain biological agents) and vaccines are extremely sensitive to temperature and must be stored under refrigeration to maintain their efficacy and safety. With the continuous improvement of medical standards, the standardized management of temperature-controlled cabinets will become a key focus for future development. Medical institutions need to establish comprehensive equipment management systems and operating procedures to ensure the safe operation and effective use of temperature-controlled cabinets.
[0003] In existing medical device storage cabinets, when it is necessary to store or retrieve medical devices that must be stored at a constant temperature, the action of opening and closing the cabinet door will cause heat exchange between the air inside and outside the cabinet. This process will directly cause fluctuations in the stable temperature environment inside the cabinet, which may affect other temperature-sensitive medical devices stored in the cabinet. Summary of the Invention

[0008] Furthermore, a sliding control panel is provided on one side of the cabinet. The sliding control panel is located inside the cabinet. A first guide groove, an inclined guide groove, and a second guide groove are provided on one side of the sliding control panel. The first guide groove, the inclined guide groove, and the second guide groove are interconnected. The sliding control column is slidably connected to the first guide groove, the inclined guide groove, and the second guide groove.
[0009] Furthermore, a hydraulic rod is installed inside the cabinet. The power output end of the hydraulic rod is fixedly connected to one side of the sliding control plate. A stop rod is slidably connected to one end of the sliding control plate. The stop rod passes through the sliding control plate, and a sliding ball is fixedly connected to one end of the stop rod.
[0010] Furthermore, the cabinet body has a first limiting groove, a first limiting straight groove, a second limiting groove, and a second limiting straight groove inside, and the sliding ball is used to slide in connection with the first limiting groove, the first limiting straight groove, the second limiting groove, and the second limiting straight groove.
[0011] Furthermore, the sliding placement plate is rotatably connected to a rotating placement frustum, which is provided with a straight sliding groove and a spiral sliding groove, and the straight sliding groove and the spiral sliding groove are interconnected.
[0012] Furthermore, an abutting wedge is slidably connected inside one side of the sliding placement plate. The inclined surface of the abutting wedge is used to abut one end of the abutting rod. A second spring is fixedly connected between the abutting wedge and the sliding placement plate. A protruding slider is fixedly connected to one side of the abutting wedge. The protruding slider is slidably connected to the straight slide groove and the spiral slide groove.
[0013] Furthermore, a sealing sliding rod is fixedly connected to the other side of the abutting inclined block, a sealing tube is slidably connected to one end of the sealing sliding rod, the sealing tube is slidably connected to the sliding placement plate, a third spring is fixedly connected between the sealing tube and the sliding placement plate, and a slot is opened inside the abutting inclined block, with a flexible tube fixedly connected to one end of the slot.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention creates a temporary, independent buffer space by installing a sliding sealing plate inside the cabinet when placing or removing medical devices. This design allows newly placed medical devices with ambient temperature to be isolated from the already temperature-controlled medical devices inside. The sealing plate will only be opened after the temperature in the isolation area is adjusted to match that in the main storage area by the temperature control system. This minimizes the impact on the overall stable temperature inside the cabinet when opening the sealing cover to place or remove medical devices, thereby effectively maintaining the stability of the temperature inside the cabinet. Second, through the cooperation of structures such as the sealing sliding rod, sealing tube and hose, the present invention generates negative pressure at the adsorption hole during the movement of the sliding placement plate and the rotation of the rotating placement platform, which firmly adsorbs the medical device onto the rotating placement platform. This design effectively prevents the medical device from slipping or shifting during the movement, ensuring the safety of the medical device; at the same time, when sterilization is completed and ready for use, the system will automatically release the adsorption for easy retrieval. Third, this invention utilizes a rotating placement frustum inside a sliding placement plate. This frustum has straight and spiral grooves, which, in conjunction with an abutting inclined block and a raised slider, drive the rotating placement frustum to rotate when the sliding placement plate moves or is abutted. This design allows medical devices placed on the rotating placement frustum to rotate with the frustum, thereby increasing the irradiation angle of the sterilization lamp on the medical devices, minimizing blind spots in the sterilization lamp's irradiation, and improving the sterilization effect. Simultaneously, since the medical devices can be sterilized again before removal, the sterilization efficiency is further improved. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0020] The present invention will be further described below with reference to embodiments.
[0021] Example: A medical device storage cabinet, such as Figures 1-10As shown, the cabinet includes a cabinet body 1. It should be noted that the outer shell of cabinet body 1 is equipped with an insulation layer. This design reduces the impact of the external environment on the interior of cabinet body 1. Simultaneously, a temperature control system is installed inside cabinet body 1, which automatically regulates the internal temperature. This temperature control system is existing technology and can be freely selected by professionals in the field, ensuring that the medical devices inside cabinet body 1 can be stored in a constant temperature environment. A pair of sealing covers 2 are slidably connected to the top of cabinet body 1. The design of the sealing covers 2 seals cabinet body 1, preventing the external environment from affecting its interior. An annular groove 3 is formed on the side wall of cabinet body 1, and multiple sliding columns 4 are slidably connected inside the annular groove 3. A fixing plate 5 is fixedly connected to one end of each sliding column 4. Limiting blocks 6 are provided on the upper and lower sides inside cabinet body 1. The design of the limiting blocks 6 prevents the sliding placement plate 8 from sliding during movement. The placement plate 8 is rotated excessively to prevent it from becoming inverted. A control groove 7 is provided on one side of the fixed plate 5, and the sliding placement plate 8 is slidably connected inside the control groove 7. The design of the control groove 7 can restrict the position of the sliding placement plate 8, allowing it to slide within a predetermined trajectory and preventing positional deviation during sliding. The design of the sliding placement plate 8 provides a platform for placing medical devices. A first spring 9 is fixedly connected between the fixed plate 5 and the sliding placement plate 8. The design of the first spring 9 provides power for the subsequent reset of the sliding placement plate 8. A sterilization lamp 38 is installed inside the cabinet 1. The design of the sterilization lamp 38 can sterilize the surface of the medical device packaging shell. The sterilization lamp 38 is existing technology and can be freely selected by professionals in this field. It should be noted that the medical devices in this solution all include packaging boxes.
[0022] The cabinet 1 is equipped with a servo motor 10 and a pair of drive gears 11. One side of the drive gear 11 is fixedly connected to the power output end of the servo motor 10. The two drive gears 11 are meshed and connected by a synchronous belt 12. One side of the synchronous belt 12 is fixedly connected to the other end of the slide column 4. Through the design of the servo motor 10, the rotation of the servo motor 10 can drive the synchronous belt 12 through the drive gear 11, so that the synchronous belt 12 can drive the slide column 4, the fixed plate 5 and the sliding placement plate 8 to move together. This allows the medical device on the sliding placement plate 8 to be moved directly to the top of the cabinet 1 when it is necessary to retrieve the medical device on the sliding placement plate 8. It should be noted that, through the design of the sliding column 4 and the synchronous belt 12 being rotatably connected, and with the assistance of the limiting block 6, when the synchronous belt 12 drives the sliding column 4, the fixed plate 5 and the sliding placement plate 8 to move, especially when sliding to both ends of the annular groove 3, the fixed plate 5 may drive the sliding placement plate 8 to swing together. Through the design of the limiting block 6, the position of the fixed plate 5 can be restricted, so that when the fixed plate 5 rotates to a certain angle, one side of the fixed plate 5 will abut against the limiting block 6, preventing the fixed plate 5 from driving the sliding placement plate 8 to rotate excessively. It should be noted that during the process of the synchronous belt 12 driving the fixed plate 5 to move, the sliding placement plate 8 is always located close to the lower end of the fixed plate 5.
[0023] The cabinet 1 has a pair of sliding sealing plates 13 inside. The sealing plates 13 are used to divide the interior of the cabinet 1 into partitions. Each side of the sealing plate 13 is fixedly connected to a sliding control column 14. Through the design of the sealing plates 13, when medical devices need to be placed in the cabinet, the interior of the cabinet 1 can be sealed under the action of the sealing plates 13, reducing the impact of the external environment on the interior of the cabinet 1. At the same time, the newly placed medical devices and the space in that area can be cooled down before the sealing plates 13 are opened, reducing the impact on other medical devices.
[0024] A sliding control plate 15 is provided on one side of the cabinet 1. The sliding control plate 15 is located inside the cabinet 1. A first guide groove 16, an inclined guide groove 17, and a second guide groove 18 are provided on one side of the sliding control plate 15. The first guide groove 16, the inclined guide groove 17, and the second guide groove 18 are interconnected. The sliding control column 14 is slidably connected to the first guide groove 16, the inclined guide groove 17, and the second guide groove 18. The inclined guide groove 17 guides the sliding control column 14, so that the sliding control columns 14 on both sides can drive the sealing plates 13 on both sides to merge towards the middle.
[0025] A hydraulic rod 19 is installed inside the cabinet 1. The power output end of the hydraulic rod 19 is fixedly connected to one side of the sliding control plate 15. Through the design of the hydraulic rod 19, the sliding control plate 15 can be driven to slide. One end of the sliding control plate 15 is slidably connected to an abutment rod 20, which passes through the sliding control plate 15. One end of the abutment rod 20 is fixedly connected to a sliding ball 21.
[0026] The cabinet 1 has a first limiting groove 22, a first limiting straight groove 23, a second limiting groove 24, and a second limiting straight groove 25 inside. The sliding ball 21 is used to slide in connection with the first limiting groove 22, the first limiting straight groove 23, the second limiting groove 24, and the second limiting straight groove 25. The sliding ball 21 is guided by the first limiting groove 22, the first limiting straight groove 23, the second limiting groove 24, and the second limiting straight groove 25, so that the sliding ball 21 can drive the abutment rod 20 to slide.
[0027] The sliding placement plate 8 is internally connected to a rotating placement frustum 26. The rotating placement frustum 26 has a straight slide groove 27 and a spiral slide groove 28. The straight slide groove 27 and the spiral slide groove 28 are interconnected. Through the design of the rotating placement frustum 26 and the sliding placement plate 8, the rotating placement frustum 26 can drive the medical device placed on the rotating placement frustum 26 to rotate, so that the area of the medical device is irradiated by the sterilization lamp 38 is larger.
[0028] An abutting inclined block 29 is slidably connected inside one side of the sliding placement plate 8. The inclined surface of the abutting inclined block 29 is used to abut one end of the abutting rod 20. A second spring 30 is fixedly connected between the abutting inclined block 29 and the sliding placement plate 8. A raised slider 31 is fixedly connected to one side of the abutting inclined block 29. The raised slider 31 is slidably connected to the straight slide groove 27 and the spiral slide groove 28. Through the design of the raised slider 31 being slidably connected to the spiral slide groove 28, the rotating placement platform 26 can be rotated.
[0029] A sealing sliding rod 32 is fixedly connected to the other side of the abutting inclined block 29. A sealing tube 33 is slidably connected to one end of the sealing sliding rod 32. The sealing tube 33 is slidably connected to the sliding placement plate 8. A third spring 34 is fixedly connected between the sealing tube 33 and the sliding placement plate 8. A slot 35 is opened inside the abutting inclined block 29. A hose 36 is fixedly connected to one end of the slot 35. Multiple suction holes 37 are provided on the rotating placement truncated cone 26. One end of the suction hole 37 is fixedly connected to the hose 36. Through the design of the sliding connection between the sealing sliding rod 32 and the sealing tube 33, the sealing sliding rod 32 can generate suction when it slides in the sealing tube 33. Then, the medical device is adsorbed through the slot 35, the hose 36 and the suction hole 37, so that the medical device can be firmly adsorbed on the rotating placement truncated cone 26. It should be noted that the width of the abutment rod 20 is sufficient. When the abutment rod 20 supports the bottom of the sliding placement plate 8, it will not cause the sliding column 4 to rotate. At the same time, the abutment rod 20 will not come into contact with the hose 36 when it is in contact with the abutment inclined block 29.
[0030] A first rack 39 is fixedly connected to one side of the sealing cover 2. A transmission gear 40 is meshed with one side of the first rack 39. The transmission gear 40 is rotatably connected to the inside of the cabinet 1. A second rack 41 is meshed with the other side of the transmission gear 40. The second rack 41 is slidably connected to the inside of the cabinet 1. The other end of the second rack 41 is fixedly connected to one side of the sliding control plate 15. The upper end of the second rack 41 has a section without teeth. With this design, when the sealing cover 2 is opened later, the sealing plate 13 can first isolate the space before opening the sealing cover 2.
[0031] When it is necessary to remove the medical devices from inside cabinet 1, the servo motor 10 is activated, which drives the synchronous belt 12 to move the required sliding placement plate 8 and the medical devices to the upper part of the cabinet 1. Then, the hydraulic rod 19 is activated. Figure 5 The hydraulic rod 19 drives the sliding control plate 15 to slide upward. As the sliding control plate 15 slides upward, it drives the first guide groove 16, the inclined guide groove 17, and the second guide groove 18 to slide together. This causes the sliding control columns 14 on both sides to move closer to the center under the guidance of the inclined guide groove 17. The sliding control columns 14 can drive the sealing plate 13 to slide together, so that the sealing plates 13 on both sides can be connected to seal the bottom of the cabinet 1. It should be noted that even if there are gaps in some places, it will not affect the temperature at the bottom of the cabinet 1. As the sliding control plate 15 slides upward, it drives the abutment rod 20 and the sliding ball 21 to slide upward together. At this time, the sliding ball 21 first slides within the first limiting groove 22. While the sliding ball 21 slides within the first limiting groove 22, see... Figure 5 Guided by the first limiting groove 22, the sliding ball 21 can slide to the left, allowing one end of the abutment rod 20 to slide down the sliding placement plate 8. When the sliding ball 21 slides to the junction of the first limiting groove 22 and the first limiting straight groove 23, the abutment rod 20 has moved to one side of the abutment block 29 but has not yet contacted its inclined surface. Subsequently, the sliding control plate 15 continues to drive the abutment rod 20 to slide upward. At this time, the sealing plates 13 on both sides have completed the docking. At the same time, the sliding control column 14 slides inside the first guide groove 16. Through the design of the first guide groove 16, it can be ensured that the subsequent upward sliding of the sliding control plate 15 is not affected. As the sliding control plate 15 continues to slide upwards, the sliding ball 21 slides inside the first limiting groove 23, causing the abutment rod 20 to slide upwards along with the sliding placement plate 8. This allows the sliding placement plate 8 to move the medical device towards the sterilization lamp 38, facilitating the removal of the medical device. When the sliding ball 21 slides within the second limiting groove 24, guided by the second limiting groove 24, the sliding ball 21 slides to the left, causing the sliding ball 21 to drive the abutment rod 20 to abut against the inclined surface of the abutment block 29. Through the abutment rod 20 against the inclined surface of the abutment block 29, the abutment block 29... 9 slides into the sliding placement plate 8. While the contact block 29 slides into the sliding placement plate 8, it drives the raised slider 31 to slide together, so that the raised slider 31 slides inside the spiral groove 28. With the cooperation of the raised slider 31 and the spiral groove 28, the rotating placement platform 26 rotates. While the rotating placement platform 26 rotates, it drives the medical device to rotate together, so that before the medical device is taken out of the cabinet 1, the surface of the medical device is sterilized again by the sterilization lamp 38. By rotating, the sterilization lamp 38 can irradiate all sides of the medical device. At this time, the sliding ball 21 slides inside the second limiting straight groove 25. See Figure 7 As the abutting inclined block 29 slides into the sliding placement plate 8, it drives the sealing sliding rod 32 to slide upwards. Simultaneously, under the action of the third spring 34, the sealing tube 33 is pulled upwards, preventing the sealing sliding rod 32 from sliding inside the sealing tube 33. This design ensures that the adsorption force at the adsorption hole 37 is not affected. When the protruding slider 31 slides to the straight slide groove 27, the third spring 34 no longer pulls on the sealing tube 33, while providing some support. At this point, as the abutting inclined block 29 continues to slide into the sliding placement plate 8, it drives... The sealing sliding rod 32 slides inside the sealing tube 33, allowing it to compress the gas inside the sealing tube 33. This causes the gas inside the sealing tube 33 to be blown through the slot 35 and the hose 36 to the adsorption hole 37, thereby releasing the adsorption of the medical device. At this time, the protruding slider 31 slides inside the straight sliding groove 27. This design ensures that the adsorption of the medical device is released only after the rotating placement truncated cone 26 has finished rotating the medical device, preventing the medical device from being thrown off during the rotation process. Meanwhile, the sliding ball 21 continues to slide inside the second limiting straight groove 25. After the sterilization lamp 38 completes the sterilization of the medical devices, the teeth of the second rack 41 begin to contact the transmission gear 40. At the same time, the sliding control plate 15 continues to slide upward. As the sliding control plate 15 slides upward, it drives the second racks 41 on both sides to slide together, so that the second racks 41 drive the transmission gear 40. By driving the transmission gear 40, the transmission gear 40 is rotated. As the transmission gear 40 rotates, it drives the first rack 39, so that the sealing covers 2 on both sides slide to both sides, so that the sealing covers 2 can be opened, making it convenient to take out the medical devices in the cabinet 1. It should be noted that the maximum distance that the second rack 41 can slide is just enough to drive the sealing covers 2 on both sides to engage, so that the inside of the cabinet 1 can be sealed.
[0032] The medical devices to be placed in cabinet 1 are then placed on the rotating placement platform 26. At this time, the temperature control system begins to cool the temperature above the sealing plate 13 and activates the hydraulic rod 19, causing the sliding control plate 15 to slide downwards. The second rack 41 slides downwards along with it. During the downward sliding of the second rack 41, it drives the transmission gear 40, causing the transmission gear 40 to rotate in the opposite direction. This allows the sealing covers 2 on both sides to slide towards the center, enabling the sealing covers 2 to align and seal the cabinet 1. When the temperature drops to the same level as the temperature below the sealing plate 13, the sliding control plate 15 slides downwards, causing the abutment rod 20 and the sliding ball 21 to slide downwards together. Simultaneously, the sliding placement plate 8 slides downwards under the action of the first spring 9. When the sliding ball 21 slides downwards into the second limiting groove 24, guided by the second limiting groove 24, the sliding ball 21 pulls the abutment rod 20 to slide to the right. As the abutment rod 20 slides to the right, the abutment block 29 gradually slides downwards under the action of the second spring 30, causing the protruding slider 31 to slide inside the straight sliding groove 27. Simultaneously, the sealing sliding rod 32 slides inside the sealing tube 33. As the sealing sliding rod 32 slides downwards from the top of the sealing tube 33, a negative pressure is generated inside the sealing tube 33. This pressure, through the slot 35, hose 36, and suction hole 37, adsorbs the medical device, allowing it to be adsorbed onto the rotating placement platform 26. After adsorption of the medical device is complete, as the contacting inclined block 29 continues to slide downwards, the protruding slider 31 slides inside the spiral groove 28, causing the rotating placement platform 26 to rotate along with the medical device. The rotation of the medical device... This design ensures that all angles of the medical devices are irradiated by the sterilization lamp 38, reducing contamination inside the cabinet 1. At this time, the hydraulic rod 19 continuously pulls the sliding control plate 15 downward, allowing the sliding control column 14 to slide the sealing plate 13 to both sides under the guidance of the inclined guide groove 17, thus removing the partitioning of the internal space of the cabinet 1. Subsequently, the temperature control system above is turned off, reducing energy waste. Through this design, newly placed medical devices can be placed in the same space as other medical devices after undergoing cooling and sterilization, minimizing the impact on other medical devices.
[0033] In this embodiment: by sliding the sliding control plate 15, the sealing plates 13 on both sides inside the cabinet 1 are controlled. When taking out or putting in medical devices, an independent buffer space can be temporarily created inside the cabinet 1. This design can isolate the newly put-in medical devices with ambient temperature from the medical devices that have been kept at a constant temperature inside. The sealing plate 13 will only be opened after the temperature in the isolation area is adjusted to be consistent with the main storage area by the temperature control system. This minimizes the impact on the overall stable temperature inside the cabinet 1 when taking out or putting in medical devices by opening the sealing cover 2, so that the overall temperature inside the cabinet 1 is not affected when new medical devices are put in or taken out. Through the cooperation of structures such as the sealing sliding rod 32, the sealing tube 33, and the flexible tube 36, when the placement plate moves and the rotating platform rotates, the cooperation of the sealing sliding rod 32 and the sealing tube 33 creates a negative pressure at the adsorption hole 37, which firmly adsorbs the medical device onto the rotating placement platform 26. This design effectively prevents the medical device from slipping or shifting during movement. At the same time, when sterilization is completed and the device is ready to be used, the adsorption will be automatically released for easy retrieval. By rotating the truncated cone 26, the medical device can be rotated, further increasing the irradiation angle of the sterilization lamp 38 on the medical device and minimizing the blind spot of the sterilization lamp 38.
