Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical assistive device technology, specifically to a limb support device for paralyzed patients. Background Technology
[0002] Paralyzed patients need to use limb support devices to assist with rehabilitation training and daily life due to limited limb motor function.
[0003] Most existing limb support devices adopt a fixed structure. Although they can provide stable support, the fixed structure is difficult to adjust according to the length and shape of the patient's limb during use, resulting in low patient comfort and inability to move within a certain range, which affects rehabilitation effect and quality of life.
[0004] Therefore, a limb support device for paralyzed patients is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a limb support device for paralyzed patients in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A limb support device for paralyzed patients includes a base, a lifting and adjusting mechanism fixedly installed on the top surface of the base, a crossbeam fixedly installed at the top of the lifting and adjusting mechanism, a winding mechanism fixedly installed on the bottom surface of the crossbeam, a rope body provided on the opposite side of the crossbeam and on the winding mechanism, and a rubber support seat slidably sleeved on the surface of the rope body. A ratchet locking mechanism is provided on the winding mechanism and the crossbeam for locking the position of the rope body after the winding mechanism adjusts the winding.
[0007] Furthermore, a caster wheel is fixedly installed on the bottom surface of the base, and a braking structure is provided on the caster wheel.
[0008] Furthermore, the lifting and adjusting mechanism includes a sleeve rod fixedly installed on the top surface of the base, a rod body is vertically and movably inserted inside the sleeve rod, and several sets of adjusting holes are opened on the surface of the rod body. A pin is inserted into one of the adjusting holes on the sleeve rod and the surface of the rod body.
[0009] Furthermore, the winding mechanism includes a support frame fixedly installed on the bottom surface of the crossbeam, a rotating shaft rotatably inserted into the support frame, a handwheel fixedly installed at the end of the rotating shaft, and two sets of winches fixedly sleeved on the surface of the rotating shaft.
[0010] Furthermore, one end of the rope is fixedly installed on the crossbeam, and the other end is wound around the winch.
[0011] Furthermore, the ratchet locking mechanism includes a ratchet body fixedly sleeved on the middle surface of the rotating shaft, a stepped pull rod movably inserted into the top of the crossbar, and a spring sleeved on the surface of the stepped pull rod. The two ends of the spring are fixedly connected to the opposite surfaces of the crossbar and the stepped pull rod, respectively. A locking pin is fixedly installed at the bottom end of the stepped pull rod, and the locking pin engages with the tooth groove on the surface of the ratchet body.
[0012] The beneficial effects of this utility model are as follows: The overall height of the crossbeam is adjusted by a lifting and adjusting mechanism to roughly align it with the patient's limb. The rope is wound up by a winding mechanism to precisely adjust the suspension height of the rubber support seat fitted on the rope surface, thereby lifting the patient's limb to a comfortable suspension position. Because the rope is flexible, it remains movable after the patient's limb is fixed by the rubber support seat. The ratchet locking mechanism locks the winding mechanism after the height adjustment is completed to prevent the rope from retracting under the weight of the limb, ensuring the stability and safety of the support.

[0018] like Figures 1 to 5 As shown, a limb support device for paralyzed patients includes a base 1, a lifting adjustment mechanism 3 is fixedly installed on the top surface of the base 1, and a crossbeam 4 is fixedly installed on the top of the lifting adjustment mechanism 3. like Figure 1 and Figure 3 As shown, specifically, the lifting adjustment mechanism 3 includes a sleeve rod 301 fixedly installed on the top surface of the base 1. A rod body 302 is vertically and movably inserted inside the sleeve rod 301, and several sets of adjustment holes 303 are opened on the surface of the rod body 302. A pin 304 is inserted into one of the adjustment holes 303 on the sleeve rod 301 and the surface of the rod body 302.
[0019] More specifically, the rod 302 slides vertically within the sleeve 301, thereby driving the top crossbar 4 to rise and fall as a whole. When the crossbar 4 is adjusted to the required height, the pin 304 is inserted into the hole on the sleeve 301 and the corresponding adjustment hole 303 on the surface of the rod 302. By utilizing the principle that the pin 304 bears shear force, the rigid connection and fixation between the rod 302 and the sleeve 301 are achieved, thus completing the vertical adjustment and positioning.
[0020] A winding mechanism 5 is fixedly installed on the bottom surface of the cross frame 4. A rope 6 is provided on the opposite side of the cross frame 4 and on the winding mechanism 5, and a rubber support seat 7 is slidably sleeved on the surface of the rope 6. like Figure 2 and Figure 4As shown, specifically, the winding mechanism 5 includes a support frame 501 fixedly installed on the bottom surface of the cross frame 4, a rotating shaft 502 rotatably inserted into the support frame 501, a handwheel 503 fixedly installed at the end of the rotating shaft 502, and two sets of winches 504 fixedly sleeved on the surface of the rotating shaft 502.
[0021] More specifically, turning the handwheel 503 can drive the rotating shaft 502 and the two winches 504 fixedly mounted on it to rotate synchronously. The rotation of the winches 504 realizes the winding or releasing of the rope 6, thereby precisely controlling the lifting and lowering of the rubber support seat 7 mounted on the surface of the rope 6 and making fine adjustments to the support height.
[0022] In practical applications, one end of the rope 6 is fixedly installed on the crossbeam 4, and the other end is wound around the winch 504.
[0023] More specifically, when the winch 504 rotates to wind up, the rope 6 is shortened, raising the rubber support 7; conversely, when the winch 504 reverses to release the rope, the effective length of the rope 6 increases, and the rubber support 7 descends under the action of gravity.
[0024] The winding mechanism 5 and the crossbeam 4 are equipped with a ratchet locking mechanism 8, which is used to lock the position of the rope 6 after the winding mechanism 5 adjusts the winding. like Figure 3 and Figure 5 As shown, specifically, the ratchet locking mechanism 8 includes a ratchet body 801 fixedly sleeved on the middle surface of the rotating shaft 502, a stepped pull rod 802 movably inserted into the top of the crossbar 4, and a spring 803 sleeved on the surface of the stepped pull rod 802. The two ends of the spring 803 are fixedly connected to the opposite surfaces of the crossbar 4 and the stepped pull rod 802, respectively. A locking pin 804 is fixedly installed at the bottom end of the stepped pull rod 802, and the locking pin 804 engages with the tooth groove on the surface of the ratchet body 801.
[0025] More specifically, the ratchet body 801 rotates synchronously with the shaft 502. Under the elastic force of the spring 803, the locking pin 804 at the bottom of the step lever 802 is continuously pressed against the tooth groove of the ratchet body 801. When the shaft 502 rotates in the winding direction, the locking pin 804 can slide over the inclined surface of the tooth groove, allowing rotation. When the shaft 502 has a tendency to rotate in the opposite direction, the locking pin 804 will be locked on the vertical surface of the tooth groove, forming a mechanical self-lock to prevent accidental fall. When it is necessary to actively release the rope, lift the step lever 802 upwards to disengage the locking pin 804 from the ratchet body 801 to release the lock.
[0026] like Figure 1 and Figure 2 As shown, in practical applications, a caster wheel 2 is fixedly installed on the bottom surface of the base 1, and a braking structure is provided on the caster wheel 2.
[0027] More specifically, the casters 2 installed on the bottom of the base 1 enable the entire device to move flexibly, making it easy to move between different wards or home environments. The braking structure integrated on the casters 2 can reliably lock the device after it is positioned.
[0028] In summary: The lifting adjustment mechanism 3 is used to adjust the overall height of the crossbeam 4 so that it is roughly aligned with the patient's limb. The winding mechanism 5 winds up the rope 6 to precisely adjust the suspension height of the rubber support seat 7 fitted on the surface of the rope 6, thereby lifting the patient's limb to a comfortable suspension position. Because the rope 6 is in a flexible state, it can still remain movable after the patient's limb is fixed by the rubber support seat 7. The ratchet locking mechanism 8 locks the winding mechanism 5 after the height adjustment is completed to prevent the rope 6 from retracting under the weight of the limb, ensuring the stability and safety of the support.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
