Description

Technical Field

[0001] This utility model relates to the field of medical device delivery technology, and in particular to an electric trolley for transporting and handing over medical devices in a hospital with a limiting structure. Background Technology

[0002] Before the surgery begins, the scrub nurse needs to transfer the surgical instruments required during the surgery from the hospital supply room to the operating room. Since a single surgery often uses multiple surgical instruments, it is inevitable to use a transport trolley during the transfer process. For example, the utility model patent with patent authorization announcement number CN208725878U discloses an orthopedic medical device trolley.

[0003] However, the aforementioned medical instrument trolleys and existing similar transport trolleys mostly rely on manual pushing. However, the hospital supply room is far from the operating room, and the transport trolleys loaded with surgical instruments are often heavy. Scrub nurses often need to travel between the hospital supply room and the operating room multiple times a day, which places a heavy physical burden on them and also leads to excessively long transport times per trip.

[0004] In response to the above situation, existing technologies have developed transfer carts that are combined with two-wheeled balance bikes. These carts can provide electric assistance to the transfer carts, thereby reducing the time spent on transfers and the physical burden on scrub nurses. However, these transfer carts still have drawbacks in actual use. For example, scrub nurses can only stand on the balance bikes during transfers and cannot sit, making them uncomfortable to use. In addition, they lack necessary restraint structures, and the transfer carts are prone to unnecessary movement due to external impacts when placed, resulting in less than ideal performance in actual use.

[0005] Therefore, it is necessary to invent an electric trolley with a limiting structure for the transfer and handover of medical devices in hospitals to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an electric trolley for transporting and transferring medical devices in hospitals, featuring a limiting structure. By incorporating a folding seat and a limiting mechanism, in the normal state, the two limiting legs, under the action of torsion springs, lift the extension plate, causing the extension plate to detach the moving and traveling wheels from the ground, thus preventing the device from moving arbitrarily. Subsequently, when the L-shaped support plate is flipped and the seat cushion is rotated to a horizontal position, the medical examiner sits on the top of the seat cushion and steps on the top of the pedal. The pedal compresses the return spring and simultaneously moves the rack downwards. The downward movement of the rack drives the gear to rotate, which in turn drives the limiting legs to rotate via the connecting shaft, causing the limiting legs to detach from the ground. At this point, the moving and traveling wheels contact the ground. This addresses the problems mentioned in the background art, where medical examiners can only stand on the trolley during transport, unable to sit, resulting in insufficient comfort, and the lack of a necessary limiting structure, making the trolley prone to unnecessary movement due to external impacts, leading to unsatisfactory practical use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure, comprising:

[0008] A trolley assembly for carrying and placing medical devices;

[0009] An electric assist mechanism is used to drive the trolley assembly to move.

[0010] A folding seat for use by an instrument nurse; and

[0011] A limiting mechanism, comprising a return spring, a pedal, a rack, a fixed plate, a connecting shaft, limiting legs, and gears;

[0012] The system includes four return springs, each fixedly positioned at one of the four corners of the top of the extension plate. The pedal is fixedly positioned at the top of the four return springs and slidably sleeved on the outside of the column in a vertical direction. The rack is fixedly positioned at the bottom of the pedal. The fixing plate is fixedly positioned at the bottom of the extension plate. The connecting shaft passes through the fixing plate and is rotatably connected to the fixing plate via a bearing. The limiting leg and the gear are sequentially fixedly sleeved on the outside of the connecting shaft from the outside to the inside. The gear meshes with the rack. The torsion spring is sleeved on the outside of the connecting shaft and fixedly connected between the fixing plate and the limiting leg.

[0013] According to at least one embodiment of the present disclosure, an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure includes a trolley body, a railing, and casters. The railing is fixedly mounted on the trolley body, and the casters are rotatably nested on the bottom left side of the trolley body via bearings.

[0014] According to at least one embodiment of the present disclosure, an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure includes an electric assist mechanism comprising an extension plate, a movable wheel, a column, and a rotating shaft. The extension plate is fixedly disposed at the bottom right side of the trolley body. The movable wheel is rotatably nested at the bottom right side of the extension plate via bearings. The column is fixedly disposed through the top left side of the extension plate. The rotating shaft is rotatably disposed inside the column via bearings.

[0015] According to at least one embodiment of the present disclosure, an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure further includes a handle, a bracket, and a travel wheel. The handle is fixedly disposed through the top of the side of the rotating shaft, the bracket is fixedly disposed at the bottom end of the rotating shaft, and the travel wheel is rotatably nested inside the bracket via a bearing.

[0016] According to at least one embodiment of the present disclosure, an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure includes an electric assist mechanism that further includes a drive motor and a switch. The drive motor is fixedly mounted on the side of the support and is connected to the drive wheel via a transmission. The switch is fixedly mounted on the outside of the handle. A rechargeable battery is fixedly mounted at the bottom of the extension plate. Both the drive motor and the rechargeable battery are electrically connected to the switch.

[0017] According to at least one embodiment of the present disclosure, an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure includes a folding seat comprising an L-shaped support plate, a seat cushion, and a magnet. The L-shaped support plate is rotatably connected to the right side of a column via a hinge. The seat cushion is fixedly disposed at the end of the L-shaped support plate. The magnet is fixedly disposed through the L-shaped support plate and magnetically connected to the column.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] This invention features a foldable seat and a limiting mechanism. In the normal state, the two limiting legs, under the action of torsion springs, lift the extension plate, causing the extension plate to detach the moving and traveling wheels from the ground, thus preventing the device from moving arbitrarily. Subsequently, when the L-shaped support plate is flipped and the seat cushion rotates to a horizontal position, the scrub nurse sits on the top of the seat cushion and steps on the top of the pedal. The pedal compresses the return spring and simultaneously moves the rack downwards. The rack's downward movement drives the gear to rotate, which in turn drives the limiting legs to rotate via the connecting shaft, causing the limiting legs to detach from the ground. At this point, the moving and traveling wheels contact the ground. Compared to existing similar devices, this invention allows scrub nurses to use either a sitting or standing posture, further reducing physical exertion and providing greater comfort. Simultaneously, the device effectively limits movement in the normal state, preventing unnecessary movement and resulting in a more ideal practical effect. Attached Figure Description

[0030] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0032] Figure 2 This is a schematic diagram of the trolley assembly 1 of an electric trolley for transporting and transferring medical devices in a hospital, which has a limiting structure, according to one embodiment of the present disclosure.

[0033] Figure 3 This is a schematic diagram of the electric assist mechanism 2 and folding seat 3 of an electric trolley for transporting and transferring medical devices in a hospital with a limiting structure, according to one embodiment of the present disclosure.

[0034] Figure 3 This is a schematic diagram of the limiting mechanism 4 of an electric trolley for transporting and transferring medical devices in a hospital, according to one embodiment of the present disclosure.

[0035] like Figures 1-4 As shown, the electric trolley for transporting and transferring medical devices in hospitals with a limiting structure disclosed herein may include components such as: trolley assembly 1, electric assist mechanism 2, folding seat 3, and limiting mechanism 4.

[0036] like Figure 2 As shown in this disclosure, the trolley assembly 1 includes a trolley body 11, a guardrail 12, and casters 13. The guardrail 12 is fixedly mounted on the trolley body 11, and the casters 13 are rotatably nested on the bottom left side of the trolley body 11 via bearings.

[0037] Therefore, surgical instruments can be placed on the trolley body 11, while the guardrail 12 can block the surgical instruments and prevent them from falling off the trolley body 11.

[0038] like Figure 3 As shown, in a preferred embodiment, the electric power assist mechanism 2 includes an extension plate 21, a movable wheel 22, a column 23, a rotating shaft 24, a handle 25, a bracket 26, a travel wheel 27, a drive motor 28, and a switch 29. The extension plate 21 is fixedly mounted on the bottom right side of the trolley body 11. The movable wheel 22 is rotatably nested at the bottom right side of the extension plate 21 via bearings. The column 23 is fixedly and continuously mounted through the top left side of the extension plate 21. The rotating shaft 24 is rotatably mounted inside the column 23 via bearings. The handle 25 is fixedly and continuously mounted through the top side of the rotating shaft 24. The bracket 26 is fixedly mounted at the bottom end of the rotating shaft 24. The travel wheel 27 is rotatably nested inside the bracket 26 via bearings. The drive motor 28 is fixedly mounted on the side of the bracket 26 and is connected to the travel wheel 27 via a transmission connection. The switch 29 is fixedly mounted outside the handle 25. A rechargeable battery is fixedly mounted at the bottom of the extension plate 21. Both the drive motor 28 and the rechargeable battery are electrically connected to the switch 29.

[0039] Therefore, when switch 29 is turned on, the rechargeable battery supplies power to drive motor 28, which drives the travel wheel 27 to rotate. The travel wheel 27 then drives the extension plate 21 to move via the moving wheel 22 through bracket 26, rotating shaft 24 and column 23. When the extension plate 21 moves, it drives the trolley body 11 to move synchronously through caster wheels 13. During the movement, the handle 25 drives the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, it drives the travel wheel 27 to rotate through bracket 26, thereby adjusting the direction of travel.

[0040] like Figure 3 As shown in this disclosure, the folding seat 3 includes an L-shaped support plate 31, a seat cushion 32, and a magnet 33. The L-shaped support plate 31 is rotatably connected to the right side of the column 23 via a hinge. The seat cushion 32 is fixedly disposed at the end of the L-shaped support plate 31. The magnet 33 is fixedly disposed through the L-shaped support plate 31 and is magnetically connected to the column 23.

[0041] This allows the seat cushion 32 to be pulled, causing the L-shaped support plate 31 to rotate to a horizontal position. At this point, the scrub nurse can sit on top of the seat cushion 32, thereby reducing the scrub nurse's physical exertion and making the use more comfortable.

[0042] like Figure 4As shown, in a preferred embodiment, the limiting mechanism 4 includes a return spring 41, a pedal 42, a rack 43, a fixing plate 44, a connecting shaft 45, a limiting leg 46, and a gear 47. Four return springs 41 are provided, and each of the four return springs 41 is fixedly disposed at one of the four corners of the top of the extension plate 21. The pedal 42 is fixedly disposed at the top of the four return springs 41 and is slidably sleeved on the outside of the column 23 in the vertical direction. The rack 43 is fixedly disposed at the bottom of the pedal 42. The fixing plate 44 is fixedly disposed at the bottom of the extension plate 21. The connecting shaft 45 passes through the fixing plate 44 and is rotatably connected to the fixing plate 44 via a bearing. The limiting leg 46 and the gear 47 are sequentially fixedly sleeved on the outside of the connecting shaft 45 from the outside in. The gear 47 meshes with the rack 43. The torsion spring 48 is sleeved on the outside of the connecting shaft 45 and fixedly connected between the fixing plate 44 and the limiting leg 46.

[0043] Therefore, under normal conditions, the two limiting legs 46 lift the extension plate 21 under the action of the torsion spring 48, so that the extension plate 21 drives the moving wheel 22 and the traveling wheel 27 to detach from the ground, thereby preventing the device from moving arbitrarily. When the instrument nurse steps on the top of the pedal 42, the pedal 42 compresses the return spring 41 and drives the rack 43 to move down. When the rack 43 moves down, it drives the gear 47 to rotate. When the gear 47 rotates, it drives the limiting legs 46 to rotate through the connecting shaft 45, thereby causing the limiting legs 46 to detach from the ground. At this time, the moving wheel 22 and the traveling wheel 27 are in contact with the ground.
