Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a mobile trolley for orthopedic operating rooms. Background Technology

[0002] Operating room trolleys are a common medical device, typically used to store surgical instruments. Existing trolleys have multiple small drawers. While this design increases the variety of items that can be stored compared to large storage compartments, it reduces the storage capacity of each drawer. For instruments that are used extensively during surgery, medical staff have to frequently pull out and retrieve these small drawers, which is very inconvenient. Summary of the Invention

[0003] To address the problems in existing technologies, this invention provides a mobile trolley for orthopedic operating rooms that combines multiple small drawers into several large, layered storage compartments, increasing storage capacity and solving the problem of medical staff having to frequently pull out small drawers during surgery. It also uses an electric telescopic rod to push out and automatically unfold the storage compartments, making it convenient for medical staff to use.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a mobile trolley for orthopedic operating rooms, including a box body, multiple handrails on the box body, multiple casters on the box body, a first partition on the box body, a second partition on the box body, an electrical control mechanism on the box body, and multiple loading mechanisms on the box body; the loading mechanism includes a first slide groove on the box body, an electric telescopic rod on the box body, a pull-out plate on the first slide groove, a front panel on the pull-out plate, an item indicator component on the front panel, a remaining quantity indicator component on the front panel, a storage component on the pull-out plate, a traction component on the pull-out plate, and a limiting hole on the front panel. The housing is the main body of the mobile cart. The platform above the housing can hold the equipment record sheet. The casters are locking casters to prevent rolling during use. The first partition is a horizontal partition used to distinguish between sterile and non-sterile equipment; sterile equipment is above the first partition, and non-sterile equipment is below. The electrical control mechanism controls the operation of the electric telescopic rod, allowing it to extend and retract. The electric telescopic rod connects to the front panel, driving its movement. The front panel connects to the pull-out panel, engaging with the first slide rail. Therefore, the electric telescopic rod also drives the pull-out panel along the first slide rail. Above the pull-out panel is a storage component for storing medical equipment used during surgery. An item indicator component indicates the type of equipment stored in the storage component, and a remaining quantity indicator indicates whether the equipment in the storage component needs replenishment. A traction component links the electric telescopic rod and the storage component, automatically unfolding after the storage component extends. A limiting hole restricts the movement distance of the traction component to prevent excessive stretching.

[0005] Specifically, the storage assembly includes a first storage device mounted on a pull-out panel, a second storage device mounted on a first storage cabinet, two third storage cabinets mounted on the second storage cabinet, and a linkage device mounted on the first, second, and third storage devices. The first, second, and third storage devices are all used to store medical equipment used during surgery. The linkage device is used for linkage, allowing the third storage cabinets and the second storage device to open simultaneously.

[0006] Specifically, the first storage device includes a first storage cabinet mounted on a pull-out panel, a first rotating shaft disposed within the first storage cabinet, a fourth sliding groove disposed on the first storage cabinet, a first rotating plate disposed on the first rotating shaft, a second rotating plate disposed on the first rotating shaft, a plurality of first pads disposed on the first storage cabinet, and a plurality of first springs disposed on the first storage cabinet. The first rotating shaft can slide along the fourth sliding groove, one end of the first rotating shaft is connected to a traction assembly, the first rotating plate and the second rotating plate can rotate around the first rotating shaft, the first pads are used to limit the position of the first rotating plate and the second rotating plate to prevent excessive rotation, the first springs are used for resetting, and when the first rotating plate and the second rotating plate are collinear, the first springs are neither compressed nor stretched.

[0007] Specifically, the second storage device includes two second storage cabinets mounted on the first storage cabinet, a second rotating shaft inside the second storage cabinet, a third rotating plate mounted on the second rotating shaft, multiple second pads inside the second storage cabinet, multiple second springs inside the second storage cabinet, a first slider inside the second storage cabinet, and a third spring mounted on the first slider. The third rotating plate can rotate around the second rotating shaft. The second pads restrict the position of the third rotating plate to prevent excessive rotation. One end of the first slider is a ramp, and its height is flush with the second pad. When not in use, the first slider holds the third rotating plate in place, keeping it horizontal. At this time, the second spring is compressed. When the second storage cabinet is unfolded, the third spring pulls the first slider to move, and one side of the third rotating plate loses support. The second spring then lifts one side of the third rotating plate.

[0008] Specifically, the linkage device includes a third rotating shaft symmetrically arranged on the first storage device, a fourth rotating shaft symmetrically arranged on the first storage device, a fifth rotating shaft symmetrically arranged on the second storage device, a sixth rotating shaft symmetrically arranged on the second storage device, a seventh rotating shaft symmetrically arranged on the second storage device, an eighth rotating shaft symmetrically arranged on the third storage cabinet, a ninth rotating shaft symmetrically arranged on the third storage cabinet, a sector gear symmetrically arranged on the third rotating shaft, a first connecting rod fixed on the sector gear and sleeved on the third and fifth rotating shafts, a second connecting rod sleeved on the fourth, sixth, and eighth rotating shafts, a third connecting rod sleeved on the seventh and ninth rotating shafts, a fourth connecting rod sleeved on the sector gear, and a tenth rotating shaft sleeved on the fourth connecting rod. When unfolded, the traction assembly pulls the tenth rotating shaft downwards, causing the fourth link to rotate around the tenth rotating shaft. The angle between the two fourth links increases. The fourth link is simultaneously mounted on the sector gear. During rotation, the fourth link exerts a downward force on the sector gear, causing it to rotate. Using the front view as a reference, the left sector gear rotates counter-clockwise. The left first link is fixed to the left sector gear, so it rotates counter-clockwise around the third rotating shaft along with the left sector gear. The other end of the left first link is mounted on the fifth rotating shaft. Therefore, the counter-clockwise rotation of the left first link causes the left second storage compartment to unfold to the left. The left sixth rotating shaft is mounted on the left second storage compartment. The left second link is mounted on the left fourth rotating shaft and the left sixth rotating shaft. On the rotating shaft and the eighth rotating shaft on the left, during the process of the second storage cabinet on the left unfolding to the left, the sixth rotating shaft on the left applies a force to the left to the second connecting rod on the left. Therefore, the second connecting rod on the left rotates around the fourth rotating shaft on the left, thereby applying a force to the left to the eighth rotating shaft on the left, causing the third storage cabinet on the left to unfold to the left. Because the distance from the eighth rotating shaft on the left to the fourth rotating shaft on the left is longer than the distance from the sixth rotating shaft on the left to the fourth rotating shaft on the left, the third storage cabinet on the left will be to the left of the second storage cabinet after unfolding. The ninth rotating shaft on the left is located on the third storage cabinet on the left, and the seventh rotating shaft on the left is located on the second storage cabinet on the left. The third connecting rod on the left is sleeved on the seventh rotating shaft on the left and the ninth rotating shaft on the left to maintain the stability of the third storage cabinet on the left when unfolding. Similarly, when the sector gear on the right rotates clockwise, the first linkage on the right will also rotate clockwise. The second storage cabinet on the right will then unfold to the right along with the first linkage. The second linkage will then rotate clockwise, causing the third storage cabinet on the right to unfold to the right as well. Once unfolded, the third storage cabinet will be located to the right of the second storage cabinet. When unfolded, the second storage cabinet will partially obscure the first storage cabinet, and the third storage cabinet will partially obscure the second storage cabinet. This design reduces the size of the storage mechanism when unfolded, minimizing space usage while increasing storage capacity. Furthermore, compared to a single large storage cabinet, the three-tiered design reduces the depth of the storage cabinet, making it easier for medical staff to access equipment.

[0009] Specifically, the traction assembly includes a telescopic rod disposed inside the housing, a traction line disposed on the telescopic rod, a first through hole disposed on the pull-out plate, a rotating shaft bracket disposed on the pull-out plate, an eleventh rotating shaft disposed on the rotating shaft bracket, a roller disposed on the eleventh rotating shaft, a first traction block disposed on the traction line, a first bracket disposed on the front panel, a fourth spring disposed on the first bracket, and a second traction block disposed on the fourth spring. The rollers limit and guide the traction line. The telescopic rod can extend and retract. When the telescopic rod is fully extended, the storage unit is just fully extended from the cabinet. One side of the traction line is connected to the second traction block and the fourth spring, and the other side is connected to the telescopic rod. The resistance on the telescopic rod side is smaller, so during the extension of the pull-out panel, the traction line will first pull the telescopic rod to extend. When the telescopic rod is fully extended, one side of the telescopic rod cannot extend further and will pull the traction line in the opposite direction, thereby pulling the first and second traction blocks downward, which in turn stretches the fourth spring. The first traction block is connected to the first rotating shaft, driving the first rotating shaft to move downward. The second traction block is sleeved on the tenth rotating shaft, driving the tenth rotating shaft to move downward, thereby driving the fourth connecting rod to rotate, which in turn drives the second and third storage cabinets to unfold. After unfolding, the traction line is in a taut state. The force exerted by the telescopic rod on the traction line is greater than the contraction force of the fourth spring, so the second and third storage cabinets will not retract. When the pull-out panel retracts, the traction cable slackens, and the force exerted by the telescopic rod on the traction cable is less than the contraction force of the fourth spring. Therefore, the fourth spring will contract, causing the tenth rotating axis to move upward, which in turn causes the second and third storage cabinets to retract.

[0010] Specifically, the item indicator assembly includes a base on the front panel, a second slide groove on the base, a second slider on the base and sliding along the second slide groove, a first rack on the base, a limiting device on the second slider, a pressing block on the second slider, and an observation window on the second slider. The portion of the base corresponding to the observation window is printed with the names of different medical devices. The second slider can move along the second slide groove. Pressing the limiting device releases the limiting position. Moving the second slider up and down aligns the observation window with the corresponding medical device. Releasing the limiting device, which engages with the first rack, completes the limiting position.

[0011] Specifically, the limiting device includes a cavity within the second slider, a second through hole on the second slider, a pressing rod on the second slider that slides along the second through hole, a third slider within the cavity, a third sliding groove on the third slider, a twelfth rotating shaft on the pressing rod that slides along the third sliding groove, a limiting head on the third slider, and a fifth spring on the limiting head. Pressing the pressing rod causes it to move upwards. The third sliding groove and the twelfth rotating shaft cooperate, and the upward movement of the pressing rod applies a rightward force to the third slider, causing it to move to the right and disengage the limiting head from the rack, compressing the fifth spring. After moving the second slider to the desired position, releasing the pressing rod causes the fifth spring to push the limiting head to move to the left, cooperating with the first rack to complete the limiting action. The leftward movement of the limiting head causes the third slider to move to the left, which in turn applies a downward force to the pressing rod, causing it to move downwards and reset.

[0012] Specifically, the remaining balance indicator assembly includes a base plate on the front panel, an indicator plate on the base plate, a thirteenth rotating shaft on the indicator plate, a guide rail on the front panel, a fourteenth rotating shaft on the guide rail, a gear sleeved on the fourteenth rotating shaft, a fifth connecting rod fixed on the gear and sleeved on the thirteenth and fourteenth rotating shafts, a second bracket on the front panel, a fifteenth rotating shaft on the second bracket, a sixteenth rotating shaft on the indicator plate, a sixth connecting rod sleeved on the fifteenth and sixteenth rotating shafts, a seventeenth rotating shaft on the second bracket, an eighteenth rotating shaft on the indicator plate, a seventh connecting rod sleeved on the seventeenth and eighteenth rotating shafts, a second rack on the guide rail, and a handle on the second rack. The base plate has printed text indicating that the loading mechanism needs replenishment of equipment. Pushing the handle moves the second spur rack, which engages with a gear. The fifth link is fixed on the second spur rack, so it rotates with the gear. The other end of the fifth link is fitted onto the thirteenth rotating shaft, so its rotation applies a force to the thirteenth rotating shaft. The thirteenth rotating shaft is located on the indicator plate, so the indicator plate also rotates. The indicator plate also has the sixteenth and eighteenth rotating shafts. The seventeenth and fifteenth rotating shafts are located on the second support. The sixth link is fitted onto the fifteenth and sixteenth rotating shafts, and the seventh link is fitted onto the seventeenth and eighteenth rotating shafts. Therefore, when the indicator plate rotates, the sixteenth rotating shaft applies a force to the sixth link, and the eighteenth rotating shaft applies a force to the seventh link. The sixth link rotates around the fifteenth rotating shaft, and the seventh link rotates around the seventeenth rotating shaft. Once the indicator plate is in position, the text on the base plate will be displayed, reminding medical personnel to replenish the equipment in the loading mechanism.

[0013] The beneficial effects of this invention are: (1) Combining multiple small drawers into several large layered storage compartments increases storage capacity.

[0014] (2) The storage compartment is automatically pushed out and unfolded using an electric telescopic rod, which is convenient to use.

[0015] (3) An item indicator board is provided so that medical staff can see the types of equipment stored in the storage compartments. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-13As shown, the mobile trolley for orthopedic operating rooms according to the present invention includes a housing 1, multiple handrails 2 on the housing, multiple casters 3 on the housing, a first partition 4 on the housing, a second partition 5 on the housing, an electrical control mechanism 6 on the housing, and multiple loading mechanisms 7 on the housing; the loading mechanism includes a first sliding groove 71 on the housing, an electric telescopic rod 72 on the housing, a pull-out plate 73 on the first sliding groove, a front panel 74 on the pull-out plate, an item indicator component 75 on the front panel, a remaining quantity indicator component 76 on the front panel, a storage component 77 on the pull-out plate, a traction component 78 on the pull-out plate, and a limiting hole 79 on the front panel.

[0020] Specifically, the storage assembly includes a first storage device 771 mounted on a pull-out panel, a second storage device 772 mounted on a first storage cabinet, two third storage cabinets 773 mounted on the second storage cabinet, and a connecting rod device 774 mounted on the first storage device, the second storage device, and the third storage cabinets.

[0021] Specifically, the first storage device includes a first storage cabinet 7711 mounted on a pull-out panel, a first rotating shaft 7712 mounted inside the first storage cabinet, a fourth sliding groove 7713 mounted on the first storage cabinet, a first rotating plate 7714 mounted on the first rotating shaft, a second rotating plate 7715 mounted on the first rotating shaft, a plurality of first pads 7716 mounted on the first storage cabinet, and a plurality of first springs 7717 mounted on the first storage cabinet.

[0022] Specifically, the second storage device includes two second storage cabinets 7721 disposed on the first storage cabinet, a second rotating shaft 7722 disposed inside the second storage cabinet, a third rotating plate 7723 disposed on the second rotating shaft, a plurality of second pads 7724 disposed inside the second storage cabinet, a plurality of second springs 7725 disposed inside the second storage cabinet, a first slider 7726 disposed inside the second storage cabinet, and a third spring 7727 disposed on the first slider.

[0023] Specifically, the linkage device includes a third rotating shaft 7741 symmetrically arranged on the first storage device, a fourth rotating shaft 7742 symmetrically arranged on the first storage device, a fifth rotating shaft 7743 symmetrically arranged on the second storage device, a sixth rotating shaft 7744 symmetrically arranged on the second storage device, a seventh rotating shaft 7745 symmetrically arranged on the second storage device, an eighth rotating shaft 7746 symmetrically arranged on the third storage cabinet, a ninth rotating shaft 7747 symmetrically arranged on the third storage cabinet, a sector gear 7748 symmetrically arranged on the third rotating shaft, a first connecting rod 7749 fixed on the sector gear and sleeved on the third and fifth rotating shafts, a second connecting rod 77410 sleeved on the fourth, sixth, and eighth rotating shafts, a third connecting rod 77411 sleeved on the seventh and ninth rotating shafts, a fourth connecting rod 77412 sleeved on the sector gear, and a tenth rotating shaft 77413 sleeved on the fourth connecting rod.

[0024] Specifically, the traction assembly includes a telescopic rod 781 disposed in the housing, a traction line 782 disposed on the telescopic rod, a first through hole 783 disposed on the pull-out plate, a rotating shaft bracket 784 disposed on the pull-out plate, an eleventh rotating shaft 785 disposed on the rotating shaft bracket, a roller 786 disposed on the eleventh rotating shaft, a first traction block 787 disposed on the traction line, a first bracket 788 disposed on the front panel, a fourth spring 789 disposed on the first bracket, and a second traction block 780 disposed on the fourth spring.

[0025] Specifically, the item indicator assembly includes a base 751 on the front panel, a second slide groove 752 on the base, a second slider 753 on the base and sliding along the second slide groove, a first straight rack 754 on the base, a limiting device 755 on the second slider, a pressing block 756 on the second slider, and an observation window 757 on the second slider.

[0026] Specifically, the limiting device includes a cavity 7551 disposed in the second slider, a second through hole 7552 disposed on the second slider, a pressing rod 7553 disposed on the second slider and sliding along the second through hole, a third slider 7554 disposed in the cavity, a third slide groove 7555 disposed on the third slider, a twelfth rotating shaft 7556 disposed on the pressing rod and sliding along the third slide groove, a limiting head 7557 disposed on the third slider, and a fifth spring 7558 disposed on the limiting head.

[0027] Specifically, the remaining balance indicator assembly includes a base plate 761 on the front panel, an indicator plate 762 on the base plate, a thirteenth rotating shaft 763 on the indicator plate, a guide rail frame 764 on the front panel, a fourteenth rotating shaft 765 on the guide rail frame, a gear 766 sleeved on the fourteenth rotating shaft, a fifth connecting rod 767 fixed on the gear and sleeved on the thirteenth and fourteenth rotating shafts, a second bracket 768 on the front panel, a fifteenth rotating shaft 769 on the second bracket, a sixteenth rotating shaft 7610 on the indicator plate, a sixth connecting rod 7611 sleeved on the fifteenth and sixteenth rotating shafts, a seventeenth rotating shaft 7612 on the second bracket, an eighteenth rotating shaft 7613 on the indicator plate, a seventh connecting rod 7614 sleeved on the seventeenth and eighteenth rotating shafts, a second rack 7615 on the guide rail frame, and a handle 7616 on the second rack.

[0028] In use, push the trolley to the desired position, lock the casters to prevent the trolley from moving, and control the extension of the electric telescopic rod via the electronic control mechanism, which drives the front panel to move. The front panel is connected to the pull-out panel, which moves along the first slide groove. At this time, the resistance on the side where the traction line is connected to the telescopic rod is small, so when the pull-out panel and the front panel move, the traction line will pull the telescopic rod to extend. The rollers limit and guide the traction line. When the telescopic rod is extended to its longest length, the storage component is just fully extended out of the box. The electric telescopic rod continues to extend. At this time, one side of the telescopic rod cannot extend further and will pull the traction line in the opposite direction, thereby pulling the first traction block and the second traction block to move downward, and then stretching the fourth spring.

[0029] The first traction block is sleeved on the first rotating shaft. The first rotating shaft slides down along the fourth slide groove. The first rotating plate will rotate clockwise around the first rotating shaft as the axis, and the second rotating plate will rotate counterclockwise around the first rotating shaft as the axis, thus forming a "V" shape. At this time, the first spring will be stretched.

[0030] The second traction block is fitted onto the tenth rotating shaft. The tenth rotating shaft moves downward along the limiting hole on the front panel. When it reaches the bottom of the limiting hole, the electric telescopic rod stops. The downward movement of the tenth rotating shaft drives the fourth connecting rod to rotate around the tenth rotating shaft. The angle between the two fourth connecting rods increases. The fourth connecting rod is simultaneously fitted onto the sector gear. When the fourth connecting rod rotates, it exerts a downward force on the sector gear, causing the sector gear to rotate. Taking the front view as a reference, the sector gear on the left rotates counterclockwise. The first connecting rod on the left is fixed on the sector gear on the left. Therefore, the first connecting rod on the left will rotate counterclockwise around the third rotating shaft along with the sector gear on the left. The other end of the first connecting rod on the left is fitted onto the fifth rotating shaft. Therefore, the counterclockwise rotation of the first connecting rod on the left will cause the second storage cabinet on the left to unfold to the left. The sixth rotating shaft on the left is located on the second storage cabinet on the left. The second link on the left is mounted on the fourth, sixth, and eighth rotating shafts on the left. As the second storage cabinet on the left unfolds to the left, the sixth rotating shaft on the left applies a force to the left to the second link. Therefore, the second link rotates around the fourth rotating shaft on the left, thus applying a force to the eighth rotating shaft on the left, causing the third storage cabinet on the left to unfold to the left. Because the distance from the eighth rotating shaft on the left to the fourth rotating shaft on the left is longer than the distance from the sixth rotating shaft on the left to the fourth rotating shaft on the left, the third storage cabinet on the left will be to the left of the second storage cabinet after unfolding. The ninth rotating shaft on the left is mounted on the third storage cabinet on the left, and the seventh rotating shaft on the left is mounted on the second storage cabinet on the left. The third link on the left is mounted on the seventh and ninth rotating shafts on the left to maintain the stability of the third storage cabinet on the left when it unfolds. Similarly, when the sector gear on the right rotates clockwise, the first linkage on the right will also rotate clockwise. The second storage cabinet on the right will unfold to the right along with the first linkage. The second linkage on the right will then rotate clockwise, causing the third storage cabinet on the right to unfold to the right as well. After unfolding, the third storage cabinet will be to the right of the second storage cabinet. When the second storage cabinets on both sides unfold, they will stretch the third spring. The contraction force of the third spring will pull the first slider to move. After the first slider moves, one side of the third rotating plate will lose support. The second spring will then push the third rotating plate to rotate around the second rotating axis. The third rotating plate on the left will form a "\" shape, and the third rotating plate on the right will form a " / " shape.

[0031] The aforementioned storage cabinets have partial obstructions to reduce the space occupied by the storage components when unfolded, while increasing storage capacity. Compared to a single large storage cabinet, the three-layer storage cabinet design reduces the depth of the cabinet, making it easier for medical staff to access equipment. However, equipment in the obstructed areas of the storage cabinet is not easy to retrieve. Therefore, the "V", "\", and " / " shapes formed by the rotating plate allow the equipment in the obstructed areas to slide along the ramp to the middle area, making it easier for medical staff to access the equipment.

[0032] After use, the electric telescopic rod is retracted by the electronic control mechanism. At this time, the traction rope is relaxed, and the contraction force of the fourth spring will drive the first traction block and the second traction block to move upward.

[0033] The first traction block moves upward, causing the first rotating shaft to slide upward along the fourth slide groove. In conjunction with the first spring, the first rotating plate and the second rotating plate will reset, and the first pad block plays a limiting role.

[0034] The second traction block moves upward, and the tenth rotating shaft moves upward along the limiting hole on the front plate. The upward movement of the tenth rotating shaft drives the fourth connecting rod to rotate around the tenth rotating shaft. The angle between the two fourth connecting rods will decrease. The fourth connecting rod is simultaneously sleeved on the sector gear. When the fourth connecting rod rotates, it will give the sector gear an upward force, causing the sector gear to rotate. Taking the front view as a reference, the sector gear on the left rotates clockwise. The first connecting rod on the left is fixed on the sector gear on the left. Therefore, the first connecting rod on the left will rotate clockwise with the sector gear on the left around the third rotating shaft. The other side of the first connecting rod on the left... The first connecting rod is mounted on the fifth rotating shaft. Therefore, when the first connecting rod on the left rotates clockwise, it will cause the second storage compartment on the left to retract to the right. The sixth rotating shaft on the left is mounted on the second storage compartment on the left. The second connecting rod on the left is mounted on the fourth, sixth, and eighth rotating shafts on the left. During the retraction of the second storage compartment to the right, the sixth rotating shaft on the left applies a rightward force to the second connecting rod on the left. Therefore, the second connecting rod will rotate around the fourth rotating shaft on the left, thus applying a rightward force to the eighth rotating shaft on the left, causing the third storage compartment on the left to retract to the right. Similarly, when the sector gear on the right rotates counterclockwise, the first connecting rod on the right will rotate counterclockwise, causing the second storage compartment on the right to retract to the left along with the first connecting rod on the right. The second connecting rod on the right will then rotate counterclockwise together, causing the third storage compartment on the right to retract to the left. When the electric telescopic rod is fully retracted, the reset is complete.

[0035] The item indicator on the front panel indicates to medical staff the types of equipment stored in the storage unit. The base, corresponding to the observation window, is printed with the names of different medical devices. Pressing the lever moves it upwards, engaging the third slide and the twelfth rotating shaft. The upward movement of the lever applies a rightward force to the third slider, causing it to move to the right and disengage the limiting head and rack, compressing the fifth spring. Aligning the observation window with the corresponding medical device name and releasing the lever causes the fifth spring to push the limiting head to the left, engaging the first rack to complete the limiting action. The leftward movement of the limiting head moves the third slider to the left, applying a downward force to the lever, causing it to move downwards and reset.

[0036] The remaining quantity indicator on the front panel can remind medical staff to replenish the equipment in the storage unit. The base plate has printed text indicating that the loading mechanism needs replenishment of equipment. Pushing the handle moves the second spur rack, which engages with a gear. The fifth link is fixed on the second spur rack, so it rotates with the gear. The other end of the fifth link is fitted onto the thirteenth rotating shaft, so its rotation applies a force to the thirteenth rotating shaft. The thirteenth rotating shaft is located on the indicator plate, so the indicator plate also rotates. The indicator plate also has the sixteenth and eighteenth rotating shafts. The seventeenth and fifteenth rotating shafts are located on the second support. The sixth link is fitted onto the fifteenth and sixteenth rotating shafts, and the seventh link is fitted onto the seventeenth and eighteenth rotating shafts. Therefore, when the indicator plate rotates, the sixteenth rotating shaft applies a force to the sixth link, and the eighteenth rotating shaft applies a force to the seventh link. The sixth link rotates around the fifteenth rotating shaft, and the seventh link rotates around the seventeenth rotating shaft. Once the indicator plate is in position, the text on the base plate will be displayed, reminding medical personnel to replenish the equipment in the loading mechanism.

[0037] The aforementioned casters, electronic control mechanism, and electric telescopic pole were all purchased from the market.
