Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a wearable upper limb rehabilitation training device. Background Technology
[0002] In actual daily training work, a large number of patients need rehabilitation training in order to recover more quickly. Usually, patients need to sit up and carry out rehabilitation training through traditional rehabilitation training equipment.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:
[0004] In the existing technology, most upper limb rehabilitation training devices are simply driven by a motor to assist the patient's upper limb in flexion and extension, which is not conducive to weight-bearing rehabilitation. In addition, in the existing technology, upper limb rehabilitation training devices are generally only attached to the patient's upper limb with a fixing strap. This fixing method has a low degree of stability for fixing the patient's upper limb and is prone to causing the patient's upper limb to sway, which affects the rehabilitation effect.
[0005] Therefore, those skilled in the art have provided a wearable upper limb rehabilitation training device to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wearable upper limb rehabilitation trainer that can achieve weight-bearing rehabilitation for patients and improve the fixation of the patient's upper limbs during use, preventing the patient's upper limbs from shaking and affecting the rehabilitation effect.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A wearable upper limb rehabilitation training device includes a first fixing member and a second fixing member. Clamping mechanisms are provided at the center of both sides of the inner wall of the first fixing member and the second fixing member. Each of the four clamping mechanisms includes a clamping plate. A threaded inner rod is fixedly provided at the center of one side of each of the four clamping plates. A threaded sleeve is threadedly sleeved on the outer wall of each of the four threaded inner rods.
[0009] The first fixing member has a second shaft plate fixedly installed on both sides of the rear end face, and the second fixing member has a first shaft plate fixedly installed on both sides of the front end face. The two first shaft plates are equipped with a load-bearing mechanism. The two load-bearing mechanisms include a rotating shaft. The two rotating shafts are movably sleeved with torsion springs at both ends. Nylon cloth tapes are fixedly installed at both ends of the upper end face of the first and second fixing members.
[0010] Furthermore, the four clamping plates are respectively movably disposed at the center of the inner walls of the first and second fixing members, and the four threaded sleeves are respectively rotatably disposed at the center of the outer walls of the first and second fixing members.
[0011] Furthermore, grooves are provided at both the upper and lower ends of the outer wall of the four threaded inner rods, and the four threaded inner rods slide through the center of both sides of the outer wall of the first fixing member and the second fixing member respectively.
[0012] Furthermore, the two ends of the two rotating shafts are fixedly connected to the center of the inner walls of the two first shaft plates and respectively rotate through the two second shaft plates, and the two ends of the four torsion springs are fixedly connected to the inner walls of the two first shaft plates and the two second shaft plates respectively.
[0013] Furthermore, Velcro is fixedly installed at both ends of the outer wall of the first and second fasteners, and Velcro is fixedly installed at the lower end of one side of each of the four nylon fabric tapes.
[0014] Furthermore, the first and second fixing members are provided with slots at both ends of their upper ends, and the four nylon strips are respectively fixedly installed in the four slots located on the same side of the multiple slots.
[0015] Furthermore, both sides of the lower end of the inner walls of the first and second fasteners are hollowed out, and the first fastener is hinged to the front end face of the second fastener.
[0016] This utility model has the following beneficial effects:
[0017] 1. The present invention proposes a wearable upper limb rehabilitation training device, in which the patient's upper arm and forearm are placed inside the first fixing member and the second fixing member respectively. Then, four nylon cloth strips are wrapped around from the top and four Velcro tabs are attached to four Velcro tabs respectively, thereby achieving initial fixation through the four nylon cloth strips. Then, the four threaded sleeves are rotated to move the opposing clamps on both sides, thereby achieving the clamping and fixing effect on the patient's upper limb, thus preventing the patient's upper limb from shaking during rehabilitation training and affecting the effect of rehabilitation training.
[0018] 2. The present invention proposes a wearable upper limb rehabilitation training device. After the patient wears the device, he or she performs rehabilitation training by actively flexing his or her arm. During the flexion process, the second fixing member rotates around the line connecting the two center points of the two first shaft plates and the two second shaft plates. During the rotation, the two first shaft plates rotate relative to the two second shaft plates, thereby twisting the four torsion springs to tighten them. The restoring elasticity of the torsion springs provides resistance to the patient's arm flexion movement, thereby achieving the effect of weight-bearing rehabilitation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1 to 4 One embodiment provided by this utility model:
[0027] A wearable upper limb rehabilitation training device includes a first fixing member 1 and a second fixing member 2. Clamping mechanisms 6 are provided at the center of both sides of the inner wall of the first fixing member 1 and the second fixing member 2. Each of the four clamping mechanisms 6 includes a clamping plate 601. A threaded inner rod 603 is fixedly provided at the center of one side of each of the four clamping plates 601. A threaded sleeve 602 is threadedly sleeved on the outer wall of each of the four threaded inner rods 603.
[0028] The first fixing member 1 has a second shaft plate 5 fixedly installed on both sides of the rear end face, and the second fixing member 2 has a first shaft plate 4 fixedly installed on both sides of the front end face. The two first shaft plates 4 are equipped with a load-bearing mechanism 9. The two load-bearing mechanisms 9 include a rotating shaft 901. The two ends of the two rotating shafts 901 are movably sleeved with torsion springs 902. Nylon cloth tapes 8 are fixedly installed at both ends of the upper end face of the first fixing member 1 and the second fixing member 2.
[0029] Specifically, the first fixing member 1 and the second fixing member 2 achieve the effect of supporting the patient's upper arm and forearm. Then, the nylon cloth strip 8 can initially fix the patient's upper limb to the first fixing member 1 and the second fixing member 2. Then, the clamping mechanism 6 achieves the clamping and fixing effect of the patient's upper limb, which can further improve the fixation strength, prevent the patient's upper limb from shaking during training and affecting the rehabilitation effect, and can achieve the effect of weight-bearing training through the weight-bearing mechanism 9.
[0030] Reference Figure 1 , Figure 2 Four clamping plates 601 are respectively movably disposed at the center of the inner walls of the first fixing member 1 and the second fixing member 2, and four threaded sleeves 602 are respectively rotatably disposed at the center of the outer walls of the first fixing member 1 and the second fixing member 2.
[0031] Specifically, rotating the threaded sleeve 602 can cause the threaded inner rod 603 to extend and retract, which in turn can cause the clamping plate 601 to move, thereby achieving the clamping and fixing effect on the patient's upper limb through the two clamping plates 601 located on the same straight line on both sides.
[0032] Reference Figure 1 , Figure 2 The four threaded inner rods 603 have grooves at both ends of their outer walls, and the four threaded inner rods 603 slide through the center of the outer walls of the first fixing member 1 and the second fixing member 2 respectively.
[0033] Specifically, the threaded inner rod 603 has a groove, and the first fixing member 1 and the second fixing member 2 are provided with protrusions that cooperate with the groove at their penetration points. Therefore, the rotation of the threaded inner rod 603 can be restricted when the threaded sleeve 602 is rotated, thereby enabling the threaded inner rod 603 to push the clamping plate 601 to move horizontally.
[0034] Reference Figure 3 , Figure 4 The two ends of the two rotating shafts 901 are fixedly connected to the center of the inner walls of the two first shaft plates 4 respectively and rotate through the two second shaft plates 5 respectively. The two ends of the four torsion springs 902 are fixedly connected to the inner walls of the two first shaft plates 4 and the two second shaft plates 5 respectively.
[0035] Specifically, when the patient flexes their arm, the second fixing member 2 and the first shaft plate 4 rotate relative to the first fixing member 1 via the rotating shaft 901, thereby compressing the four torsion springs 902. The change in the elastic force of the torsion springs 902 can apply resistance when the patient continues to flex their arm, thus increasing the resistance during training.
[0036] Reference Figure 1 , Figure 2The first fastener 1 and the second fastener 2 are both fixedly provided with Velcro 7 at both ends of one side of the outer wall, and the four nylon fabric tapes 8 are all fixedly provided with Velcro 3 at the lower end of one side.
[0037] Specifically, the nylon tape 8 can be wrapped around and fixed from the top of the first fixing member 1 and the second fixing member 2 by the Velcro 7 and Velcro 3, thereby achieving the initial fixation effect on the patient's upper limb.
[0038] Reference Figure 1 , Figure 2 The first fixing member 1 and the second fixing member 2 are provided with slots at both ends of the front and rear of the upper end. The four nylon cloth strips 8 are respectively fixed in the four slots located on the same side of the multiple slots.
[0039] Specifically, by using the slot to restrict the sliding of the nylon tape 8, the highest point of the nylon tape 8 is located inside the first fixing member 1 and the second fixing member 2 after the Velcro 7 and Velcro 3 are attached, thereby expanding the range of fit of the nylon tape 8 for patients with different body types and arm circumferences.
[0040] Reference Figure 1 , Figure 2 Both sides of the lower end of the inner wall of the first fixing member 1 and the second fixing member 2 are hollowed out, and the first fixing member 1 is hinged to the front end face of the second fixing member 2.
[0041] Specifically, the hollow design reduces the overall weight of the device while also providing some heat dissipation.
[0042] Working principle: The patient's upper arm and forearm are placed inside the first fixing member 1 and the second fixing member 2, respectively. Then, four Velcro tabs 3 are attached to four Velcro tabs 7, thereby achieving a preliminary fixation effect on the patient's upper limb through four nylon tapes 8. Next, rotating the threaded sleeve 602 causes the threaded inner rod 603 to move left and right, so that the two clamps 601 located on opposite sides can achieve a clamping and fixing effect on the patient's upper arm and forearm. By increasing the fixation strength of the patient's upper limb, it can prevent the patient's upper limb from shaking during rehabilitation training, which would affect the rehabilitation effect. When the patient flexes the arm, it can drive the two first axle plates 4 to rotate relative to the two second axle plates 5, thereby compressing the four torsion springs 902. The elastic change of the torsion springs 902 can provide movement resistance to the patient when flexing the arm, thereby improving rehabilitation efficiency.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
