Description

Technical Field

[0001] This utility model belongs to the field of nursing devices, and in particular relates to an internal medicine nursing device that is easy to transport. Background Technology

[0002] In neurological clinical nursing, lower limb weakness is a common symptom among elderly patients, making targeted leg function training a crucial part of rehabilitation therapy. However, existing mobility aids have significant drawbacks in practical application: firstly, traditional mobility aids have fixed structures, and their large size and non-adjustable frames after use result in significant space requirements during transport, causing inconvenience whether navigating narrow passages like elevators or corridors, or loading them into transport vehicles, greatly increasing the workload of nursing staff; secondly, even those mobility aids with folding functions have complex folding structures and cumbersome operations, and even after folding, efficient transport remains difficult. Therefore, a more easily transportable medical nursing device is needed to address these issues. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide an internal medicine nursing device that is easy to transport, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An internal medicine nursing device that is easy to transport includes a support assembly, a drive assembly, a support plate, and a support frame. The support assembly includes two vertical rods, each with a limiting groove on its adjacent side. A movable rod is slidably connected in the limiting groove. Limiting blocks are connected to both sides of each vertical rod, and a first roller is rotatably connected to the opposite side of each limiting block.

[0006] The drive assembly includes a motor, a worm gear, and a threaded rod. The motor is connected to the bottom of the vertical rod, and the output shaft of the motor is connected to the worm gear. The top end of the worm gear is fixedly connected to the threaded rod, and the threaded rod is threadedly connected inside the movable rod. Both the worm gear and the threaded rod are rotatably connected inside the vertical rod. Both sides of the worm gear are engaged with worm wheels, and the worm wheels are rotatably connected inside the vertical rod via pins.

[0007] Two worm gears on one side are connected to a support plate, and two worm gears on the other side are connected to both ends of the same support frame. The bottom of the support frame and the two support plates are all connected to second rollers.

[0008] In a further technical solution, the handrail assembly includes a rotating frame, which is rotatably connected between two movable rods. The rotating frame is arc-shaped, and both ends of the rotating frame are threaded with bolts, with both bolts abutting against the same side of the vertical rod.

[0009] A further technical solution involves connecting the two movable rods on their adjacent sides to the same waist-binding component.

[0010] In a further technical solution, the cross-sectional shape of the limiting groove is set to T-shape, and the cross-sectional shape of the movable rod is set to T-shape.

[0011] In a further technical solution, the position of the first roller corresponds to the position of the second roller.

[0012] In a further technical solution, the top of the threaded rod is located in a limiting groove, and the support frame is U-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention significantly improves transport efficiency and greatly reduces space requirements: Through a linkage mechanism of a motor-driven worm gear, threaded rod, and worm wheel, the device's height and width can be simultaneously reduced with a single click. During transport, the support plate and support frame rotate and engage with the vertical rod via the worm wheel, while the movable rod moves downward along the T-shaped limiting groove, allowing the device to quickly fold from a three-dimensional frame structure into a compact, flat form, reducing its volume by over 50%. After folding, the device's width is only the thickness of the support components, and its height is reduced to the lowest position of the movable rod, allowing it to easily pass through narrow spaces such as hospital corridors and elevators, or be quickly loaded into ambulances and nursing carts, solving the pain points of traditional devices being "large in size and difficult to transport."

[0015] This utility model makes the transfer operation intelligent and convenient: the motor drive replaces the traditional manual folding, and the caregiver only needs to control the switch to complete the shrinking / unfolding. The operation is convenient, and when the device is folded down, the first roller and the second roller form a four-point support, so it can be easily moved by pushing even on a smooth surface, avoiding the embarrassment of the traditional folding device "cannot be moved after being folded down". It is especially suitable for emergency transfer scenarios.

[0016] This utility model features a structural linkage design that enhances transport safety: the T-shaped limiting groove limits the movable rod, ensuring no wobbling or jamming during height adjustment; the meshing transmission of the worm gear and worm has a self-locking function, and after folding, the support plate, support frame, and vertical rod fit tightly together, preventing parts from loosening or accidentally unfolding during transport, thus ensuring the safety of patients and nursing staff. Compared to the "loose connection" of traditional folding devices, this device locks through a mechanical structure, significantly improving transport reliability.

[0017] This utility model features multifunctional space optimization to adapt to diverse scenarios: the rotating frame of the handrail assembly can be rotated and folded 90°, and the lateral space is further reduced after being locked with bolts, thus further improving the flexibility of transportation.

[0018] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Example 1

[0026] like Figures 1-3 As shown, this utility model embodiment provides an internal medicine nursing device that is easy to transport, including a support assembly 1, a drive assembly 2, a support plate 3, and a support frame 6. The support assembly 1 includes two vertical rods 11, and each of the two vertical rods 11 has a limiting groove 12 on its close side. A movable rod 13 is slidably connected in the limiting groove 12. Limiting blocks 14 are connected to both sides of the vertical rods 11. The cross-sectional shape of the limiting groove 12 is T-shaped, and the cross-sectional shape of the movable rod 13 is also T-shaped. The limiting groove 12 can limit the movement of the movable rod 13, so that the movable rod 13 is not easy to rotate under the action of the rotating threaded rod 23, so that the movable rod 13 can move smoothly along its axial direction under the action of the rotating threaded rod 23.

[0027] The two limiting blocks 14 are rotatably connected to the first roller 15 on their opposite sides;

[0028] The drive assembly 2 includes a motor 21, a worm gear 22, and a threaded rod 23. The motor 21 is connected to the bottom of the vertical rod 11. The output shaft of the motor 21 is connected to the worm gear 22. The top end of the worm gear 22 is fixedly connected to the threaded rod 23. The threaded rod 23 is threadedly connected to the movable rod 13. Both the worm gear 22 and the threaded rod 23 are rotatably connected to the vertical rod 11. Both sides of the worm gear 22 are engaged with the worm wheel 24. The worm wheel 24 is rotatably connected to the vertical rod 11 through the pin 25.

[0029] Two worm gears 24 on one side are connected to the support plate 3, and two worm gears 24 on the other side are connected to both ends of the same support frame 6. The top of the threaded rod 23 is located in the limiting groove 12. The support frame 6 is U-shaped. The bottom of the support frame 6 and the two support plates 3 are connected to the second rollers 7. The position of the first roller 15 corresponds to the position of the second roller 7.

[0030] In this embodiment, when the device needs to be transferred, the control motor 21 drives the worm gear 22 to reverse, and the reversed worm gear 22 drives the threaded rod 23 to reverse synchronously.

[0031] The reversed worm 22 drives the two worm wheels 24 to rotate in opposite directions. The two support plates 3 on one side rotate clockwise, so that the rotating support plate 3 contacts one side of the vertical rod 11. At this time, the first roller 15 and the second roller 7 on the same side are on the same plane.

[0032] At the same time, the support frame 6 on the other side rotates counterclockwise, so that the rotating support frame 6 contacts the other side of the vertical rod 11. At this time, the first roller 15 and the second roller 7 on the same side are in the same plane.

[0033] Simultaneously, the reversed threaded rod 23 drives the movable rod 13 to move downward within the limiting groove 12. When the support plate 3 and support frame 6 contact the vertical rod 11, the movable rod 13 contacts the bottom of the threaded rod 23. At this time, the device is adjusted in both height and width simultaneously, making operation convenient and reducing the size of the device, thus reducing the space occupied by the device and making it easy to transport. When the adjusted device is laid down, the two first rollers 15 and the two second rollers 7 simultaneously contact the ground, and the adjusted device can still move easily on the ground.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that: the hand support assembly 4 includes a rotating frame 41, which is rotatably connected between two movable rods 13. The rotating frame 41 is arc-shaped, and both ends of the rotating frame 41 are threaded with bolts 42. Both bolts 42 abut against the same side of the vertical rod 11; the side of the two movable rods 13 that are close to each other is connected to the same waisting member 5.

[0036] In this embodiment, when the two movable rods 13 move downward, the downward-moving movable rods 13 synchronously drive the waist-binding member 5 and the rotating frame 41 to move downward simultaneously, and reverse the two bolts 42. The bolts 42 disengage from the vertical rod 11. The rotating frame 41 rotates 90 degrees clockwise. The rotating frame 41 drives the bolts 42 to move above the movable rods 13. Then the bolts 42 are rotated clockwise and abut against the top of the movable rods 13. At this time, the space occupied by the rotating frame 41 in the horizontal direction is reduced, which can further reduce the size of the device.

[0037] When the device is needed, the control motor 21 drives the worm gear 22 to rotate forward. The rotating support plate 3 and support frame 6 are in contact with the upper surface of the limit block 14. At the same time, the rotating threaded rod 23 drives the waist-binding component 5 and the hand-holding assembly 4 to move upward through the movable rod 13 and to a suitable height. The waist-binding component 5 is composed of an adjustment structure connected to the vertical rod 11 and a waist-binding structure connected to the two adjustment structures, so that the height of the waist-binding structure can be further adjusted according to the actual situation. Then, the waist of the patient can be fixed through the waist-binding structure. Then, the patient holds the horizontally fixed rotating frame 41 and then the patient can use the device to perform nursing training for both legs.

[0038] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
