Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a multifunctional transport device. Background Technology

[0002] In the field of medical care, hemodialysis is an important treatment for end-stage renal disease patients to maintain their lives. For dialysis patients with severe conditions and limited mobility, frequent transfers from wheelchairs to dialysis beds are required during treatment.

[0003] Traditional methods of patient transport typically rely on manual assistance. Because patients are seated, their center of gravity is concentrated and their muscle strength is insufficient, requiring multiple medical staff to work together to lift and transport them. During lifting and transport, medical staff need to directly touch the patient's limbs to move them, which requires exerting force while avoiding injury to the patient, making it more difficult to exert force and placing a significant physical and operational burden on medical staff, thus increasing their risk of occupational diseases.

[0004] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0094] The multifunctional transfer device of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0095] Reference Figures 1 to 9 As shown, the multifunctional transfer device provided according to the embodiment of the present utility model includes a bracket 10, a first support member 20, a second support member 30 and a third support member 40.

[0096] The bracket 10 has first rollers 11 at both rear ends, second rollers 12 at both front ends, and extensions 13 at both front ends.

[0097] The first support member 20 is horizontally placed on the upper surface of the bracket 10 and is detachably connected to the upper end of the bracket 10 for the patient to sit on.

[0098] The second support member 30 is pivotally connected to the rear end of the first support member 20 and can switch between a horizontal and a vertical state to support the patient's upper body.

[0099] The third support member 40 is pivotally connected to the front end of the first support member 20 and can switch between an inclined state and a horizontal state to support the patient's leg. When the third support member 40 is in the inclined state, its bottom surface abuts against the extension 13, thereby placing the third support member 40 in the inclined state. Advantageously, the extension 13 can also be configured as a telescopic structure to facilitate adjustment of the inclination angle of the third support member 40.

[0100] The second support member 30 is provided with a first locking member 50 to lock the second support member 30 in a horizontal or vertical state, and the third support member 40 is provided with a second locking member 60 to lock the third support member 40 in a horizontal state.

[0101] Based on the above, in use, when the second support 30 and the third support 40 are both adjusted to a horizontal state, the first support 20, the second support 30, and the third support 40 can form a temporary stretcher. The first support 20 and the bracket 10 are detachable. At this time, medical staff can quickly and effortlessly transfer the patient to the hospital bed using the temporary stretcher. When the second support 30 is in a vertical state and the third support 40 is tilted, the entire device can be a wheelchair, which facilitates the transfer between wards. This utility model has a simple structure and can be quickly converted between a stretcher and a wheelchair to meet different usage needs. At the same time, it effectively reduces the workload of medical staff and reduces the probability of occupational diseases.

[0102] Preferably, in one embodiment of the present invention, the bracket 10 includes four vertical rods 14 and two connectors 16.

[0103] The four vertical rods 14 are arranged in a rectangular array, and the tops and bottoms of adjacent vertical rods 14 are connected by connecting rods 15.

[0104] The two connecting members 16 are arranged opposite each other and extend in the front-back direction. The two connecting members 16 are located above the vertical rod 14. The upper ends of the two connecting members 16 are formed with arc-shaped grooves. The first support member 20 is detachably provided on the connecting members 16 on both sides.

[0105] Thus, by distributing the four vertical bars 14 in a rectangular shape and forming a double-layer truss structure with the top and bottom connected by the connecting rods 15, the entire support 10 has a stronger load-bearing capacity, while the connecting member 16 facilitates the connection of the first support member 20.

[0106] Preferably, in one embodiment of the present invention, the first support member 20 includes a first frame 21, a first pad 22, and two fixing parts 23.

[0107] The first frame 21 has multiple insertion holes 211 on both sides of its bottom surface, and the multiple insertion holes 211 are distributed at intervals along the front-back direction. The first frame 21 has a first connecting hole 212 on both sides of its rear side and a second connecting hole 213 on both sides of its front side.

[0108] The first cushion 22 is disposed on the first frame 21 for the patient to sit on.

[0109] The two fixing parts 23 are respectively provided on both sides of the rear end of the first frame 21, and the fixing parts 23 are provided with a third connecting hole 231.

[0110] The connector 16 is provided with a plurality of pins 161, which are inserted one-to-one into the socket 211.

[0111] Thus, since multiple insertion holes 211 are provided on both sides of the bottom surface of the first frame 21, and multiple pins 161 are provided on the connector 16, the connection between the first support 20 and the bracket 10 can be achieved by inserting the multiple pins 161 and the multiple insertion holes 211 one by one. When the first support 20, the second support 30 and the third support 40 form a temporary stretcher, the first support 20 and the bracket 10 can be disassembled simply by lifting the temporary stretcher upwards, making disassembly more convenient.

[0112] As a preferred embodiment of the present invention, the connector 16 is provided with a threaded hole corresponding to the third connecting hole 231. When the second support member 30 is in a vertical state, the end of the first locking member 50 is threadedly connected to the threaded hole, which further increases the connection stability of the first support member 20 and the bracket 10.

[0113] Preferably, in one embodiment of the present invention, the second support member 30 includes a second frame 31 and a second pad 32.

[0114] The second frame 31 has first mounting holes 311 on both sides of its front end, and the first mounting holes 311 extend to the rear end of the second frame 31.

[0115] The second pad 32 is fitted onto the second frame 31 to support the patient's back.

[0116] The first locking member 50 is retractably disposed in the first mounting hole 311, and one end extends out from the front end of the second frame 31. When the second support member 30 is in a vertical state, the end of the first locking member 50 is inserted into the third connecting hole 231. When the second support member 30 is in a horizontal state, the end of the first locking member 50 is inserted into the second connecting hole 213.

[0117] Thus, since the first locking member 50 is retractably disposed in the first mounting hole 311 and one end extends from the front end of the second frame 31, when the second support member 30 is in a vertical state, the end of the first locking member 50 is inserted into the third connecting hole 231 to fix the second support member 30 in a vertical state, making it convenient for the patient to lean against. When the second support member 30 is in a horizontal state, the end of the first locking member 50 is inserted into the second connecting hole 213 to fix the second support member 30 in a horizontal state, making it convenient to use as a temporary stretcher.

[0118] Preferably, in one embodiment of the present invention, the first locking member 50 includes a first stud 51 and a first adjusting member 52.

[0119] The first stud 51 passes through the first mounting hole 311 and is threadedly connected to the first mounting hole 311.

[0120] The first adjusting member 52 is located at the end of the first stud 51 and is used to drive the first stud 51 to rotate.

[0121] Thus, since the first adjusting member 52 is directly set at the end of the first stud 51, medical staff can drive the stud to rotate by manually rotating the adjusting member without additional tools, thereby achieving a quick switch of the locking state (such as the fixation of the second support member 30 between vertical and horizontal states), which is especially suitable for efficient operation in emergency scenarios.

[0122] Meanwhile, the first stud 51 and the first mounting hole 311 are connected by threads. Utilizing the self-locking characteristics of the threaded pair, the locked state can be kept stable without external force intervention, avoiding accidental unlocking due to vibration or accidental contact, and ensuring the safety of patients during transport.

[0123] Preferably, in one embodiment of the present invention, the third support member 40 includes a third frame 41 and a third pad 42.

[0124] One end of the third frame 41 is pivotally connected to the front end of the first frame 21.

[0125] The third pad 42 is fitted onto the third frame 41 to support the patient's legs.

[0126] The third frame 41 has second mounting holes 411 on both sides of its front end. The second locking member 60 passes through the second mounting hole 411 and one end extends out from the rear end of the third frame 41. When the third support member 40 is in a horizontal state, one end of the second locking member 60 is inserted into the second connecting hole 213.

[0127] Thus, when the third support member 40 is in a horizontal position, the end of the second locking member 60 is precisely inserted into the second connecting hole 213 of the first frame 21, forming a rigid mechanical connection. This effectively prevents the support member from rotating unexpectedly due to vibration or external force during transport, ensuring the stability of the patient's leg support and reducing the risk of secondary injury. The insertion and engagement of the second locking member 60 and the second connecting hole 213 adopts a "one-click" locking logic. Medical personnel only need to push the locking member to complete the state fixation, without complicated adjustment steps, which meets the needs of rapid response in emergency scenarios.

[0128] Preferably, in one embodiment of the present invention, the second locking member 60 includes a second stud 61 and a second adjusting member 62.

[0129] The second stud 61 passes through the second mounting hole 411 and is threadedly connected to the second mounting hole 411.

[0130] The second adjusting member 62 is located at the end of the second stud 61 and is used to drive the second stud 61 to rotate.

[0131] Thus, by connecting the second stud 61 to the second mounting hole 411 with threads, the mechanical self-locking property of the threaded pair allows it to automatically maintain a locked state without external force, effectively preventing the third support member 40 from shifting position due to vibration or accidental contact during transport, and ensuring the stability of the patient's leg support. The second adjusting member 62 is directly integrated into the end of the second stud 61. Medical personnel can quickly extend and retract the locking member by manually rotating the adjusting member, completing the horizontal fixation and release without additional tools, significantly shortening operation time, and is especially suitable for efficient response in emergency scenarios.

[0132] Preferably, in one embodiment of the present invention, two foot pedals 70 are further included. The two foot pedals 70 are respectively disposed at the lower front end of the second support member 30, and the opposite sides of the two foot pedals 70 are respectively connected to the side of the extension 13 by a connecting arm 71.

[0133] Thus, the footrest 70 provides a fixed support point for the patient's feet, especially in wheelchair mode, which can prevent the risk of slipping due to the patient's center of gravity shifting forward. Together with the vertical support of the second support 30, it forms a three-point stable structure (back-hips-feet), which significantly improves the safety of sitting posture.

[0134] Preferably, in one embodiment of the present invention, a pusher portion 24 is provided on the bottom rear end of the first support member 20.

[0135] Thus, the push handle 24 is located on the bottom rear end of the first support member 20, conforming to the natural pushing and pulling motion path of the human body. Medical staff can apply force directly without adjusting their standing position, especially in narrow spaces where they can make slight adjustments to the direction with one hand, improving the flexibility of transport. Preferably, the push handle 24 can adopt an arc-shaped design that conforms to the hand grip, and the surface can be added with anti-slip texture or soft rubber coating to reduce the pressure on the hand from pushing for a long time. Combined with the steering function of the second roller 12 at the rear end of the bracket 10, it significantly reduces the torsional load on the waist of medical staff and prevents occupational strain injuries.

[0136] Preferably, in one embodiment of the present invention, the diameter of the first roller 11 is larger than that of the second roller 12, and a drive ring 111 is provided on the outer side of the first roller 11 along its circumference, so that the patient can drive the first roller 11 to rotate through the drive ring 111.

[0137] Thus, by increasing the diameter and lowering the center of gravity, the stability of the device is improved when traversing uneven ground (such as thresholds and ramps), reducing the impact of bumps on the patient. At the same time, the inertial characteristics of the large rollers facilitate long-distance movement. The drive ring 111 on the outer side of the first roller 11 conforms to the natural grip angle of the human hand, allowing the patient to drive the rollers themselves for short-distance movement, reducing dependence on medical staff and enhancing the psychological satisfaction of patients in the recovery period.

[0138] As a preferred option, such as Figure 10 As shown, in another embodiment of this utility model, the two connecting members 16 can form a detachable structure with the corresponding vertical rods 14. A support plate 80 is provided at the lower end of the bracket 10, and a connecting plate is provided between the two connecting members 16. At least one drive cylinder 81 is provided on the support plate 80, and the output end of the drive cylinder 81 is connected to the connecting plate. When the first support member 20, the second support member 30, and the third support plate 80 form a temporary stretcher, the temporary stretcher can be lifted by the drive cylinder 81 to reach a height that is compatible with the hospital bed. At this time, medical staff only need to transfer the temporary stretcher to the hospital bed, making the transfer more labor-saving.

[0139] Advantageously, the drive cylinder 81 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, selected according to actual needs. A battery and a drive control device can also be installed on the pallet 80 to control the extension and retraction of the drive cylinder 81.
