Description

Technical Field

[0001] This invention relates to the medical field, specifically to a storage device for medical wound care solution. Background Technology

[0002] Medical wound care solutions are specialized materials for wound antibacterial repair and have a wide range of clinical applications. Currently, they are typically stored in drawer-type categorized cabinets to meet the requirements of light-proof and corrosion-resistant storage. They also employ two-way sliding rails for bidirectional access and placement, while also accommodating tabletops and trolleys. The industry is gradually optimizing and iterating towards well-organized zoning, convenient operation, and compliance with medical infection control standards.

[0003] Patent CN107095756A proposes a medical wound care solution storage device, including an outer shell, an inner shell, a bottled care solution support platform, a sliding mounting seat, and a rubber suction cup. The outer shell has a base at each of its four ends. A circular sliding mounting seat is installed inside the outer shell and is set close to the inner side wall of the outer shell. The inner shell is assembled with the sliding mounting seat inside the outer shell through multiple positioning devices. The bottled care solution support platform is installed on the inner bottom of the inner shell, and the rubber suction cup is installed on the upper surface of the bottled care solution support platform.

[0004] Currently, drawer-type classification cabinets have the following problems: different types of nursing solutions need to be stored in separate boxes, and multiple boxes need to be locked and fixed one by one with the nurse's mobile cart and the boxes, which is cumbersome to disassemble and assemble, and the convenience of inter-departmental transfer is poor; in addition, the integrated single-layer two-way pull-out drawer has no one-way locking structure, and the drawer must be completely pulled out to replenish the medicines on the back, which is laborious for medical staff. Moreover, the drawer can be pulled out freely on both sides, which cannot meet the standard of retrieving medicines from the front and replenishing them from the back.

[0005] Based on this, the present invention designs a medical wound care solution storage device to solve the above problems. Summary of the Invention

[0017] Furthermore, the outer surface of the beetle-shaped locking box is in contact with the outer surface of the sliding rod, and the beetle-shaped locking box is used to limit the position of the sliding rod.

[0018] Furthermore, the one-way locking mechanism includes a rack, a gear, a rotating cam, a locking assembly, and a detachable push head. The rack is slidably connected to the sealing box body, and both ends of the rack are detachably and slidably engaged with the detachable push head. The outer surface of the rack meshes with the gear, and the outer surface of the gear is fixedly connected to the rotating cam. The rotating cam is connected to the locking assembly. A second slot is provided inside the storage drawer. The interior of the sealing box body is connected to two sets of gears, the rotating cam, and the locking assembly. The interior of the sealing box body is also connected to two sets of mirror-arranged locking assemblies for one-way locking of the storage drawer.

[0019] Furthermore, the locking assembly includes a guide plate, a limiting connecting plate, a sliding frame, a second spring, and an inclined plate block. The lower surface of the guide plate is fixedly connected to the interior of the sealing box. The interior of the guide plate is rotatably connected to the rotating convex plate. The outer surface of the guide plate is fixedly connected to the limiting connecting plate. The outer surface of the rotating convex plate is slidably connected to the sliding frame.

[0022] Furthermore, the linkage component and the one-way locking mechanism are connected via a clutch transmission component, which includes: a clutch collar slidably fitted onto the outer periphery of the sliding rod, the outer wall of the clutch collar having a helical guide groove; a transmission paddle rotatably mounted on the inner wall of the sealed box, the first end of the transmission paddle being slidably embedded in the helical guide groove, and the second end of the transmission paddle extending to the sliding path of the rack; when the sliding rod is pressed and locked, the clutch collar slides axially relative to the sliding rod and drives the transmission paddle to deflect through the helical guide groove, causing the second end of the transmission paddle to disengage from the sliding path of the rack, unlocking the sliding degree of freedom of the rack; when the sliding rod is reset, the second end of the transmission paddle re-engages into the tooth groove of the rack, locking the sliding degree of freedom of the rack.

[0023] Furthermore, it also includes an intelligent control module, which comprises: a microprocessor, fixedly installed on the top of the sealed box; multiple RFID readers, each embedded in the bottom of an independent compartment within the storage drawer separated by the card plate, each RFID reader being electrically connected to the microprocessor for reading RFID electronic tags attached to the bottom of the care solution bottle to obtain the type and expiration date information of the care solution; and an electronically controlled locking actuator, which works in conjunction with the push-button latch assembly and the one-way locking mechanism to receive locking signals from the microprocessor. The microprocessor displays the expiration date and unlock signal of the RFID reader / writer, and is embedded in the front outer surface of the sealed box. It is electrically connected to the microprocessor and displays the inventory status of the nursing solution in each independent compartment, near-expiration warning information, and the current locking direction. The microprocessor is configured to generate a near-expiration reminder signal based on the expiration date information of the nursing solution read by each RFID reader / writer and output it through the display screen. Upon receiving an externally input direction switching command, it controls the electronically controlled locking driver to drive the one-way locking mechanism to switch the pulling direction and synchronously updates the locking direction status display on the display screen.

The one-way vent valve assembly includes: a fixed ring, fixedly embedded in the inner wall of the ventilation channel; a movable valve plate, rotatably mounted on the inner side of the fixed ring via an elastic hinge, the movable valve plate having a closed position and an open position; and a moisture-absorbing filter element, detachably snapped onto the air inlet side of the fixed ring, used to dry and filter the air entering the sealed box. The movable valve plate is configured such that: when the air pressure inside the sealed box is lower than the external air pressure, the movable valve plate, under the action of the pressure difference, overcomes the elastic force of the elastic hinge and deflects from the closed position to the open position, and the external air enters the sealed box after being dried and filtered by the moisture-absorbing filter element; when the air pressure inside the sealed box is higher than or equal to the external air pressure, the movable valve plate remains in the closed position under the action of the elastic hinge.

[0025] Furthermore, the bottom plate of the storage drawer is provided with an anti-tipping limiting structure, which includes: at least one guide rail extending along the pulling direction of the storage drawer and fixedly disposed on the upper surface of the bottom plate of the storage drawer; multiple elastic clamping seats corresponding one-to-one with the card plate, each elastic clamping seat being slidably sleeved on the guide rail, and each elastic clamping seat being elastically connected to the rear side wall of the storage drawer through a limiting spring; an arc-shaped clamping arm disposed at the upper end of each elastic clamping seat, the opening direction of the arc-shaped clamping arm facing the front side of the storage drawer, used to clamp the neck of the nursing solution bottle placed in the storage drawer; when the storage drawer is pulled outward, the elastic clamping seat, under the pulling force of the limiting spring, drives the arc-shaped clamping arm to move towards the rear side of the storage drawer, so that the clamping center of the arc-shaped clamping arm is offset relative to the body of the nursing solution bottle in the opposite direction of the pulling direction, forming an anti-tipping biasing torque.

[0026] Furthermore, a progressive damping retaining structure is provided between the sliding rod and the sealing box. This progressive damping retaining structure includes: a damping sleeve fixedly fitted onto the middle of the sliding rod; the outer circumferential surface of the damping sleeve is sequentially divided axially into a first damping section, a transition section, and a second damping section; the diameters of the first and second damping sections are equal and both larger than the diameter of the transition section; and a plurality of circumferentially distributed damping balls embedded in the inner wall of the annular sleeve, each damping ball being elastically connected to the inner wall of the annular sleeve via a damping spring; when the… When the sliding rod is in the initial position, each of the damping balls abuts against the outer peripheral surface of the first damping section, providing a first damping force; when the sliding rod is pressed to the locked position, each of the damping balls crosses the transition section and abuts against the outer peripheral surface of the second damping section, providing a second damping force, the second damping force being greater than the first damping force; when the sliding rod is reset from the locked position to the initial position under the action of the first spring, the abutment switching process between each of the damping balls and the second and first damping sections generates a vibration damping effect.

[0027] Compared with the prior art, the beneficial effects of this invention are as follows: 1. By setting up a linkage fixing mechanism, the sealing box body can be interlocked with other sealing boxes body. Moreover, by pushing the linkage fixing mechanism inside a single sealing box body, the linkage fixing mechanism inside each sealing box body can be moved, thereby interlocking and fixing multiple sets of sealing boxes body. At the same time, a one-way locking mechanism is set up. In normal use, the storage drawer can only be pulled out from one side. By pushing the one-way locking mechanism to adjust the direction of the one-way locking, the storage drawer can be pulled out from the other side, which is convenient for replenishing the nursing fluid inside the rear of the storage drawer and facilitates medical operations.

[0028] 2. By setting a second inclined block, when the sliding rod moves in the opposite direction to release the fixation, the second inclined block pushes the T-shaped plate to rise, and the push of the first spring causes the top edge of the second inclined block to contact the T-shaped plate, so that the T-shaped plate will not move out of the inside of the sealing box when it is not locked, making it easy to place the sealing box on a flat surface.

[0029] 3. By setting a limiting connecting plate, the rotation of the rotating convex plate is limited when it rotates, so that the rotating convex plate stops when it reaches a horizontal or vertical position. This can stably push the sliding frame up and down, and realize one-way locking of the storage drawer.

[0030] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0038] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0039] The present invention proposes a medical wound care solution storage device, including a sealed box 1 and a storage drawer 2, the sealed box 1 and the storage drawer 2 being slidably connected, and the interior of the storage drawer 2 being fitted with a card plate for dividing the interior of the storage drawer 2.

[0040] The sealed box 1 has two sets of linkage fixing mechanisms 3 symmetrically installed inside for linkage fixing of the storage drawer 2;

[0041] The sealed box 1 is equipped with a one-way locking mechanism 4 for one-way locking of the sealed box 1.

[0042] The linkage fixing mechanism 3 includes a protrusion 31, a linkage component 33, a fixing component 34, and a press-type ball lock component 35. The outer surface of the sealing box 1 is fixedly connected to the protrusion 31. A groove 32 is provided on the outer surface of the sealing box 1. The linkage component 33 is connected to the sealing box 1. The fixing component 34 and the press-type ball lock component 35 are both connected to the sealing box 1. The protrusion 31 is engaged with the groove 32 on another sealing box 1. The linkage component 33 is connected to the fixing component 34 and the press-type ball lock component 35. The fixing component 34 is used to engage the sealing box 1 with each other. The press-type ball lock component 35 is used to lock the position of the fixing component 34.

[0043] In this embodiment, the position of the card plate inside the storage drawer 2 is adjusted to facilitate the placement of the care solution, and then it is slid into the interior of the sealed box 1. At this time, the sealed box 1 and another sealed box 1 are engaged with each other by the protrusion 31 and the groove 32. Then, the linkage component 33 is pushed to move, and the linkage component 33 pushes the fixing component 34, causing the fixing component 34 to move out. At the same time, the linkage component 33 drives the push-type ball lock component 35 to move. The push-type ball lock component 35 fixes the fixed component 34 in the position where it has moved out. When the linkage component 33 moves, it pushes the linkage component 33 inside the other sealed box 1 to move, causing the fixing component 34 inside the other sealed box 1 to move out, and then fixes it by the push-type ball lock component 35. The mechanism is designed to move the linkage component 33 inside one sealed box 1, thereby moving the linkage component 33 inside another sealed box 1, thus fixing multiple sealed boxes 1 in a coordinated manner. The multiple fixing components 34 that are moved out engage with the corresponding slots on the surface of the nurse's mobile cart, fixing the sealed box 1 and the storage drawer 2. Then, the storage drawer 2 is locked in one direction by the one-way locking mechanism 4, so that the storage drawer 2 can only be moved out from the inside of the sealed box 1 in one direction. When it is necessary to replenish the nursing fluid at the back of the storage drawer 2, the one-way locking mechanism 4 is pushed to allow the storage drawer 2 to be moved out in the opposite direction inside the sealed box 1 without having to be completely moved out of the storage drawer 2, which facilitates the replenishment of the nursing fluid at the back of the storage drawer 2.

[0044] In some embodiments, such as Figures 1-7 As shown, this is a preferred embodiment of the present invention.

[0045] In this embodiment, the linkage component 33 includes a sliding rod 331, a first spring 332, and an annular sleeve 333. The sliding rod 331 is slidably connected to the inside of the sealed box 1. The outer surface of the sliding rod 331 is fixedly connected to the left end of the first spring 332, and the right end of the first spring 332 is fixedly connected to the annular sleeve 333. The outer surface of the sliding rod 331 is slidably connected to the inside of the annular sleeve 333. The first spring 332 is used to elastically push the sliding rod 331.

[0046] The outer surface of the annular sleeve 333 is fixedly connected to the inner surface of the sealing box 1. The two sides of the sliding rod 331 are fixedly connected to two sets of first springs 332. The two sets of first springs 332 are used to push the sliding rod 331. The outer surface of the sliding rod 331 is connected to two sets of fixing components 34 for fixing the four corners of the sealing box 1.

[0047] The fixing component 34 includes a T-shaped clamping plate 341, a first inclined block 342, and a second inclined block 343. The T-shaped clamping plate 341 is slidably connected to the interior of the sealing box 1. The outer surface of the sliding rod 331 is fixedly connected to the first inclined block 342 and the second inclined block 343. A first slot 344 is provided on the upper surface of the sealing box 1. The slot of the T-shaped clamping plate 341 contacts the top edge of the second inclined block 343. The lower surface of the T-shaped clamping plate 341 has the same shape as the outer surface of the first slot 344. The first inclined block 342 and the second inclined block 343 are used to push the T-shaped clamping plate 341.

[0048] The T-shaped plate 341 is slidably connected to the sliding rod 331. The outer surface of the first inclined block 342 is in contact with the outer surface of the annular sleeve 333. The annular sleeve 333 is used to limit the movement of the sliding rod 331. The T-shaped plate 341 is used to engage with the first slot 344 on another sealed box 1.

[0049] The push-button latch assembly 35 includes a fixed plate 351, a beetle latch box 352, and a latch head 353. The fixed plate 351 is fixedly connected to the interior of the sealed box 1. The outer surface of the fixed plate 351 is fixedly connected to the beetle latch box 352. The latch head 353 is fixedly connected to the sliding rod 331. The beetle latch box 352 and the latch head 353 are engaged. The beetle latch box 352 and the latch head 353 are used to fix the position of the sliding rod 331.

[0050] The outer surface of the Beetle Lock Box 352 is in contact with the outer surface of the sliding rod 331, and the Beetle Lock Box 352 is used to limit the position of the sliding rod 331.

[0051] In this embodiment, the position of the card plate inside the storage drawer 2 is adjusted to facilitate the placement of the care solution, and then it is slid into the interior of the sealing box 1. At this time, the sealing box 1 and another sealing box 1 are engaged with each other by the protrusion 31 and the groove 32. Then, the sliding rod 331 is pushed to move, and the first spring 332 is compressed due to the obstruction of the annular sleeve 333. At the same time, the sliding rod 331 drives the first inclined block 342 and the second inclined block 343 to move. The inclined surface of the first inclined block 342 presses the T-shaped card plate 341, causing the T-shaped card plate 341 to move downward and move out of the interior of the sealing box 1. At the same time, the sliding rod 331 drives the ball-abutting head 353 to move. 53 engages with the beetle lock box 352 to fix the position of the sliding rod 331. While the sliding rod 331 moves, the side of the sliding rod 331 presses against the sliding rod 331 inside another sealed box 1, causing the T-shaped card plate 341 inside the other sealed box 1 to move out. The moved T-shaped card plate 341 engages with the first slot 344 on the upper surface of the other sealed box 1 to fix the four corners of the sealed box 1. The multiple T-shaped card plates 341 moved out from the bottom sealed box 1 engage with the corresponding slots on the surface of the nurse's mobile cart, thereby linking and fixing multiple sealed boxes 1 to the surface of the nurse's mobile cart.

[0052] When the linkage is released, push the sliding rod 331 again in the direction of movement, so that the sliding rod 331 drives the ball head 353 to move. The ball head 353 moves inside the beetle lock box 352, releasing the beetle lock box 352 from the ball head 353. And through the push of the first spring 332, the sliding rod 331 moves in the opposite direction. The sliding rod 331 drives the first inclined block 342 and the second inclined block 343 to move. The second inclined block 343 pushes the T-shaped plate 341, so that the T-shaped plate 341 rises and moves into the interior of the sealed box 1, releasing the linkage of the T-shaped plate 341.

[0053] Then, the storage drawer 2 is locked in one direction by the one-way locking mechanism 4, so that the storage drawer 2 can only be moved out from one direction inside the sealed box 1. When it is necessary to add care solution to the back of the storage drawer 2, the one-way locking mechanism 4 is pushed to allow the storage drawer 2 to be moved out in the opposite direction inside the sealed box 1. It is not necessary to completely remove the storage drawer 2, which makes it convenient to add care solution to the back of the storage drawer 2.

[0054] In some embodiments, such as Figures 1-7As shown, in a preferred embodiment of the present invention, the one-way locking mechanism 4 includes a rack 41, a gear 42, a rotating convex plate 43, a locking assembly 44, and a detachable push head 46. The rack 41 is slidably connected to the sealing box 1, and both ends of the rack 41 are detachably and slidably engaged with the detachable push head 46. The outer surface of the rack 41 meshes with the gear 42, and the outer surface of the gear 42 is fixedly connected to the rotating convex plate 43. The rotating convex plate 43 is connected to the locking assembly 44. A second slot 45 is provided inside the storage drawer 2. The inside of the sealing box 1 is connected to two sets of gears 42, the rotating convex plate 43, and the locking assembly 44. The inside of the sealing box 1 is connected to two sets of mirror-arranged locking assemblies 44 for one-way locking of the storage drawer 2.

[0055] The locking assembly 44 includes a guide plate 441, a limiting connecting plate 442, a sliding frame 443, a second spring 444, and an inclined block 445. The lower surface of the guide plate 441 is fixedly connected to the interior of the sealing box 1. The interior of the guide plate 441 is rotatably connected to the rotating convex plate 43. The outer surface of the guide plate 441 is fixedly connected to the limiting connecting plate 442. The outer surface of the rotating convex plate 43 is slidably connected to the sliding frame 443. The sliding frame 443 is slidably connected to the guide plate 441. The interior of the sliding frame 443 is fixedly connected to the second spring 444. The top of the second spring 444 is fixedly connected to the inclined block 445. The inclined block 445 is slidably connected to the sliding frame 443. The second spring 444 is used to elastically push the inclined block 445.

[0056] When the upper surface of the long end of the rotating convex plate 43 contacts the lower surface of the sliding frame 443, the top edge of the inclined block 445 contacts the upper surface of the second slot 45. When the upper surface of the short end of the rotating convex plate 43 contacts the lower surface of the sliding frame 443, the top edge of the inclined block 445 contacts the lower surface of the second slot 45. The long end of the rotating convex plate 43 on the left is vertical, and the long end of the rotating convex plate 43 on the right is horizontal. The limiting connecting plate 442 is used to limit the rotating convex plate 43.

[0057] In this embodiment, when the removed T-shaped card plate 341 engages with the first slot 344 on the upper surface of another sealed box 1, the four corners of the sealed box 1 are fixed, and the multiple T-shaped card plates 341 removed from the bottom of the sealed box 1 engage with the corresponding slots opened on the surface of the nurse mobile cart, thereby linking and fixing multiple sealed boxes 1 and fixing them to the surface of the nurse mobile cart.

[0058] Pull the storage drawer 2 to the left. The second slot 45 inside the storage drawer 2 presses against the inclined block 445 on the left side, causing the inclined block 445 to move downward. The inclined block 445 moves inside the sliding frame 443, allowing the storage drawer 2 to move from the inside of the sealed box 1 from the left side. When the storage drawer 2 is pushed to the right, the inclined block 445 on the left side engages with the second slot 45 through the pushing of the locking component 44, thus blocking the movement of the storage drawer 2 and preventing the storage drawer 2 from moving out from the left side while being able to move out from the right side.

[0059] At this time, a detachable push head 46 is engaged inside the rack 41, and the rack 41 is moved to the right by the detachable push head 46, causing the two sets of gears 42 to rotate counterclockwise. The left gear 42 drives the left rotating cam 43 to rotate counterclockwise, and the rotation angle is limited by the limiting connecting plate 442, so that the rotating cam 43 rotates from vertical to horizontal and no longer obstructs the sliding frame 443. At the same time, the sliding frame 443 falls due to gravity and moves vertically downward by the guide plate 441. The short end of the rotating convex plate 43 contacts the lower surface of the sliding frame 443, and the sliding frame 443 drives the internal inclined plate block 445 to move downward, so that the top edge of the left inclined plate block 445 contacts the lower surface of the second slot 45. At the same time, the right rotating convex plate 43 rotates counterclockwise. Meanwhile, due to the restriction of the meshing of the rack 41 and the gear 42 by the left limiting connecting plate 442, the right rotating convex plate 43 rotates to a vertical position, and the long end of the rotating convex plate 43 contacts the upper surface of the inclined plate block 445.

[0060] At this time, pulling the storage drawer 2 to the right causes the second slot 45 inside the storage drawer 2 to press the right-side inclined block 445, causing the inclined block 445 to move downwards. The inclined block 445 moves inside the sliding frame 443, allowing the storage drawer 2 to move from the inside of the sealed box 1 from the right side. When the storage drawer 2 is pushed to the left, the right-side inclined block 445 engages with the second slot 45 through the pushing of the locking component 44, thus blocking the movement of the storage drawer 2 and preventing the storage drawer 2 from moving out from the right side while being able to move out from the left side.

[0061] At this time, add care solution inside the rear of the storage drawer 2, and then push the storage drawer 2 back into the sealed box 1. At this time, pull out the detachable push head 46, engage it with the right side of the rack 41, and push the rack 41 to the left so that the rack 41 meshes with the gear 42. The gear 42 rotates clockwise, and through the above movement process, the left inclined block 445 rises and the right inclined block 445 falls, so that the storage drawer 2 can return to the initial state, which can only be pulled out from the left side and the right side is restricted.

[0062] The linkage assembly 33 is connected to the one-way locking mechanism 4 via a clutch transmission assembly. This clutch transmission assembly includes a clutch collar and a transmission paddle. The clutch collar is slidably fitted onto the outer periphery of the sliding rod 331, and a helical guide groove is formed on the outer wall of the clutch collar. The transmission paddle is rotatably mounted on the inner wall of the sealed housing 1, with its first end slidably embedded in the helical guide groove and its second end extending onto the sliding path of the rack 41.

[0063] In operation, when medical staff press the sliding rod 331 to move it and lock it with the push-button ball locking assembly 35, the clutch collar moves with the sliding rod 331. Because the clutch collar slides axially relative to the sliding rod 331, the helical guide groove moves accordingly and drives the transmission paddle to deflect around its mounting axis. This causes the second end of the transmission paddle to disengage from the sliding path of the rack 41. At this time, the sliding degree of freedom of the rack 41 is unlocked, and medical staff can freely push the rack 41 to switch the locking direction of the one-way locking mechanism 4. When the sliding rod 331 resets under the action of the first spring 332, the second end of the transmission paddle deflects in the opposite direction and re-engages into the tooth groove of the rack 41, locking the sliding degree of freedom of the rack 41 and preventing the one-way locking mechanism 4 from switching directions due to vibration or accidental contact when not in operation.

[0064] The clutch transmission assembly achieves interlocking between the linkage fixing mechanism and the one-way locking mechanism. When the sealed box 1 is not locked, the direction switching function of the one-way locking mechanism 4 is automatically locked, preventing the storage drawer 2 from accidentally falling out when the box is not fixed. When the sealed box 1 is fixed, the direction switching function of the one-way locking mechanism 4 is automatically unlocked. The operation logic is clear and safe, further improving the convenience of operation for medical staff and the safety of use of the device.

[0065] The medical wound care solution storage device also includes an intelligent control module. This intelligent control module includes a microprocessor, multiple RFID readers, an electronically controlled locking actuator, and an interactive display screen.

[0066] The microprocessor is fixedly mounted on the top of the sealed housing 1, serving as the control core of the entire intelligent management module. Multiple RFID readers are embedded in the bottom of each independent compartment within the storage drawer 2, separated by card plates. Each RFID reader is electrically connected to the microprocessor. Each RFID reader reads the RFID electronic tag attached to the bottom of the care solution bottle to automatically obtain the type and expiration date information of the care solution. An electrically controlled locking actuator works in conjunction with the push-button latch assembly 35 and the one-way locking mechanism 4 to receive locking and unlocking signals from the microprocessor, enabling electrically powered locking and unlocking control. An interactive display screen is embedded on the front outer surface of the sealed housing 1 and electrically connected to the microprocessor, displaying the care solution inventory status, near-expiration warning information, and current locking direction in each independent compartment.

[0067] The microprocessor's specific operating logic is as follows: Based on the expiration date information of the nursing solutions read by each RFID reader, it determines in real time whether there are any nursing solutions that are about to expire. When the expiration date of any nursing solution approaches a preset threshold, it generates an expiration reminder signal and outputs it through the interactive display screen, reminding medical staff to prioritize its use or replacement. When medical staff input a direction switching command through the interactive display screen, the microprocessor controls the electronically controlled locking driver to drive the one-way locking mechanism 4 to switch the pulling direction, and simultaneously updates the locking direction status display on the interactive display screen.

[0068] By introducing RFID technology, automatic identification and intelligent management of nursing solution inventory have been achieved. Medical staff can keep track of the type and expiration date of nursing solutions in each compartment in real time without manual registration, effectively avoiding medical risks caused by expired nursing solutions. The combination of the electric locking driver and the display screen enables the directional switching of the one-way locking mechanism 4 to be electrically operated and visualized, which significantly improves the information management level of the device and the convenience of clinical use.

[0069] The rear side wall of the sealed housing 1 has a through ventilation channel, within which a one-way vent valve assembly is installed. The one-way vent valve assembly includes a retaining ring, a movable valve plate, and a moisture-absorbing filter element.

[0070] A retaining ring is fixedly embedded in the inner wall of the ventilation channel, providing a mounting base for the one-way vent valve assembly. A movable valve plate is rotatably mounted on the inner side of the retaining ring via a flexible hinge, and has a closed position and an open position. A moisture-absorbing filter element is detachably snapped onto the air inlet side of the retaining ring, used to dry and filter the air entering the sealed housing 1, ensuring that the air entering the sealed housing 1 is clean and dry, and preventing the care solution from becoming damp and deteriorating.

[0071] The working mechanism of the movable valve plate is as follows: When the internal air pressure of the sealed housing 1 is lower than the external air pressure, the movable valve plate overcomes the elastic force of the hinge under the action of the internal and external pressure difference, deflecting from the closed position to the open position. External air enters the sealed housing 1 after being dried and filtered by the moisture-absorbing filter element, balancing the air pressure inside and outside the sealed housing 1 and preventing the storage drawer 2 from being difficult to pull out due to negative pressure. When the internal air pressure of the sealed housing 1 is higher than or equal to the external air pressure, the movable valve plate remains in the closed position under the action of the elastic hinge, and the sealed housing 1 maintains a good sealing state, preventing external moisture or contaminants from entering.

[0072] The one-way vent valve assembly ensures the normal sealing performance of the sealed box 1 while automatically replenishing filtered and dried air when negative pressure is generated inside the box. This prevents the storage drawer 2 from being difficult to pull out due to negative pressure and avoids untreated external air from directly entering the box and causing contamination or moisture to the care solution. The moisture-absorbing filter is removable and replaceable, making maintenance convenient and further enhancing the device's ability to protect the care solution storage environment.

[0073] The bottom plate of storage drawer 2 is equipped with an anti-tipping limiting structure. The anti-tipping limiting structure includes at least one guide rail, multiple elastic clamping seats, and arc-shaped clamping arms disposed on the upper end of each elastic clamping seat.

[0074] The guide rail extends along the pull-out direction of the storage drawer 2 and is fixedly installed on the upper surface of the bottom plate of the storage drawer 2, providing a sliding guide base for the elastic clamps. Multiple elastic clamps correspond one-to-one with the clamping plate, each elastic clamp slidingly mounted on the guide rail, and each elastic clamp is elastically connected to the rear side wall of the storage drawer 2 via a limiting spring. Arc-shaped clamping arms are located at the upper end of each elastic clamp, with the opening of the arc-shaped clamping arms facing the front of the storage drawer 2, used to clamp the neck of the nursing solution bottle placed inside the storage drawer 2.

[0075] The specific working process is as follows: When the storage drawer 2 is pulled outward, the elastic clamping seat, under the tension of the limiting spring, drives the arc-shaped clamping arm to move towards the rear of the storage drawer 2. This causes the clamping center of the arc-shaped clamping arm to shift relative to the body of the nursing solution bottle in the opposite direction of the pulling direction, forming an anti-tipping bias torque. The direction of this bias torque is opposite to the direction of the pulling inertia force, effectively counteracting the forward tilting tendency of the nursing solution bottle due to inertia when the storage drawer 2 is pulled out quickly. When the storage drawer 2 is pushed back, the elastic clamping seat moves forward against the tension of the limiting spring under the push of the nursing solution bottle, and the arc-shaped clamping arm returns to its initial clamping position.

[0076] The beneficial effects of this embodiment are as follows: The anti-tipping limiting structure utilizes the power of the pulling action itself, and through the linkage of the limiting spring and the arc-shaped clamping arm, automatically generates an offset torque opposite to the tilting direction when the storage drawer 2 is pulled out, effectively preventing the nursing solution bottles from tilting forward or colliding with each other due to inertia when the storage drawer 2 is opened quickly; this structure does not require an additional power source, and is achieved entirely through mechanical linkage, making it simple and reliable, and significantly improving the stability and safety of the nursing solution retrieval process.

[0077] A progressive damping retaining structure is provided between the sliding rod 331 and the sealing box 1. The progressive damping retaining structure includes a damping sleeve and multiple damping balls.

[0078] A damping sleeve is fixedly fitted onto the middle of the sliding rod 331. The outer circumferential surface of the damping sleeve is sequentially divided into a first damping section, a transition section, and a second damping section along the axial direction. The diameters of the first and second damping sections are equal and both larger than the diameter of the transition section, giving the outer circumferential surface of the damping sleeve an axial profile that is convex at both ends and concave in the middle. Multiple damping balls are circumferentially evenly embedded in the inner wall of the annular sleeve 333. Each damping ball is elastically connected to the inner wall of the annular sleeve 333 through a damping spring, ensuring that the damping balls always tend to abut against the outer surface of the damping sleeve.

[0079] The progressive damping mechanism works as follows: When the sliding rod 331 is in its initial position, each damping ball abuts against the outer circumference of the first damping section. The damping spring provides the first damping force, keeping the sliding rod 331 stable when no external force is applied, preventing accidental movement due to vibration. When a medical staff member presses the sliding rod 331, the damping balls slide relative to the damping sleeve, moving from the first damping section through the transition section to the second damping section. During this process, because the diameter of the transition section is smaller than that of the first and second damping sections, the contact force between the damping balls and the damping sleeve decreases briefly, resulting in a sharp drop in damping force. This provides the medical staff with clear tactile feedback, indicating that the sliding rod 331 has passed the intermediate position. When the sliding rod 331 is pressed to the locked position, each damping ball crosses the transition section and abuts against the outer circumference of the second damping section. The damping spring provides the second damping force, which is greater than the first damping force, keeping the sliding rod 331 stable in the locked position and preventing unlocking due to accidental contact. When the sliding rod 331 is reset from the locked position to the initial position under the action of the first spring 332, each damping ball passes through the second damping section, the transition section and the first damping section in reverse order. During the contact switching process, a vibration damping effect is generated, which effectively absorbs the impact energy when the sliding rod 331 is reset, and avoids the sliding rod 331 from rigidly colliding with the inner wall of the sealing box 1, which would cause noise or damage.

[0080] The progressive damping retention structure, through the variable diameter design of the damping sleeve and the elastic contact of the damping ball, enables the sliding rod 331 to have two-stage damping force during pressing and resetting. This ensures the stable holding of the sliding rod 331 in the initial and locked positions, while also providing clear tactile feedback during pressing, helping medical staff to accurately judge the progress of the operation. The vibration damping effect during resetting effectively absorbs impact energy, reduces operating noise, extends the service life of the linkage fixing mechanism 3, and improves the pressing operation feel and reliability of the device.
