Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a bilateral lower limb synchronous perception training rehabilitation instrument. Background Art
[0002] For patients with hemiplegia, they are generally given symptomatic treatments such as thrombolysis and anticoagulation in the acute phase; rehabilitation treatment is needed after the acute phase. Postoperative rehabilitation treatment plays a very important role in the functional recovery of the affected limbs, which can reduce the patient's degree of disability, improve the patient's living treatment, and restore the patient's self-care ability.
[0003] Currently, common postoperative rehabilitation is mostly passive exercises for the unilateral affected limb (such as limb massage, electrical stimulation, passive movement, resistance and weight-bearing exercises, etc.), which are effective in relieving spasms on the affected side and increasing resistance capacity. However, when it only targets the unilateral affected limb, it is easy to cause incoordination of the bilateral limbs during the rehabilitation process, and cannot cooperate to complete coordinated exercises that require synchronous perception of the bilateral limbs, such as walking. Therefore, in order to increase the patient's proprioception recovery and the coordination ability of the bilateral limbs, postoperative rehabilitation pays more and more attention to the coordinated movement of the bilateral limbs. Summary of the invention
[0004] The utility model aims to provide a bilateral lower limb synchronous perception training rehabilitation instrument.
[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0007] Furthermore, the locking mechanism includes a locking hook hinged on the edge of the thigh support plate, and a locking ring fixed on the edge of the calf support plate and adapted to the locking hook.
[0008] Furthermore, in order to ensure that the patient's bilateral lower limbs can be firmly supported on the two leg supports, each of the thigh support, the calf support and the foot support should be provided with an elastic strap, which can be used to fasten the patient's lower limbs in the form of lacing. Of course, it is most preferred to provide a Velcro surface on one side of the elastic strap and a Velcro surface on the other side, so that the elastic strap can pass around the patient's lower limbs and be fastened through the Velcro surface and the Velcro surface.
[0009] Furthermore, positioning guide wheels are respectively arranged on the relatively inner plate edges of the two calf support plates, and the positioning guide wheels are located at the end of the calf support plate close to the foot support plate, and a positioning guide groove adapted to accommodate the positioning guide wheel is provided on the fixed plate, and the positioning guide groove is provided along the length direction of the calf support plate, and the groove depth is smaller than the radius of the positioning guide wheel. When the end of the calf support plate close to the thigh support plate is lifted upward, the end of the calf support plate away from the thigh support plate can slide stably along the positioning guide groove, thereby preventing the plate edge from rubbing against the upper surface of the fixed plate with great force.
[0010] Furthermore, in order to achieve massage stimulation of the affected limb, an electric pulse massager can be arranged on the fixed plate, and massage electrode patches can be arranged on the thigh support plate and the calf support plate on the same side of the slide groove, and the control input end of the massage electrode patch is electrically connected to the control output end of the electric pulse massager.
[0011] The advantage of the utility model is that two groups of leg supports consisting of a thigh support, a calf support and a foot support are used to support the patient's lower limbs on both sides respectively, and the active movement of the healthy lower limb is used to control the affected lower limb to move synchronously with it, so that the affected lower limb can complete exercise movements such as hooking the foot, bending the knee and raising the leg together with the healthy lower limb, thereby realizing synchronous interactive perception training of the bilateral lower limbs, facilitating the training of the deep sense of the bilateral limbs, and increasing the coordination ability of the patient's bilateral limbs, which is of great significance for the coordinated movement of the limbs after surgery.

[0019] like Figure 1-4 As shown, the bilateral lower limb synchronous perception training rehabilitation instrument of the utility model comprises a fixing plate 1, on which two groups of leg supports for supporting the patient's lower limbs are arranged, the leg supports should be kept parallel to the board surface of the fixing plate 1, and the two leg supports are composed of a thigh support plate 2 hinged on the fixing plate 1, a calf support plate 3 hinged to the thigh support plate 2, and a foot support plate 4 hinged to the calf support plate 3. In order to enable the patient's two lower limbs to be stably supported on the two leg supports, elastic bands 5 should also be arranged on the board edges of each thigh support plate 2, calf support plate 3 and foot support plate 4, and the elastic bands 5 can be used to tie the patient's lower limbs in the form of lacing. Of course, it is most preferred to set a magic hook surface 6 on one side of the elastic band 5 and a magic wool surface 7 on the other side thereof, so that the elastic band 5 can be passed around the patient's lower limbs and then be fixed by the magic hook surface 6 and the magic wool surface 7.
[0020] A connecting rod 8 is provided between the two foot support plates 4, and the two foot support plates 8 are fixedly connected as a whole through the connecting rod 8, so that the movement of one side of the foot support plate 4 can drive the synchronous movement of the other side, thereby realizing the synchronous foot-hooking movement of the patient's two lower limbs.
[0021] A locking mechanism is provided between the thigh support plate 2 and the calf support plate 3 of each set of leg support, and the locking mechanism includes a locking hook 9 hinged on the edge of the thigh support plate 2, and a locking ring 10 fixed on the edge of the calf support plate 3 and adapted to the locking hook 9. The thigh support plate 2 and the calf support plate 3 can be horizontally fixedly connected through the matching buckle of the locking hook 9 and the locking ring 10, so that the thigh support plate 2 and the calf support plate 3 can be rotated upward together to achieve the same angle inclination of the thigh support plate 2 and the calf support plate 3. Of course, the locking mechanism can also be adopted by hingedly connecting a rotating plate on the thigh support plate 2 and the calf support plate 3 respectively, and a threaded connection hole is provided at the overlap of the two rotating plates. At this time, a connecting bolt can be screwed and fixed in the threaded connection hole, so that the two rotating plates are fixed together, thereby realizing the horizontal connection of the thigh support plate 2 and the calf support plate 3.
[0022] An electric telescopic rod 11 is arranged on the fixed plate 1, and the telescopic direction is consistent with the length direction of the thigh support plate 2, and a slide groove 12 is opened on the fixed plate 1 below one side of the thigh support plate 2, which is consistent with the length direction of the thigh support plate 2. The bottom of the slide groove 12 is inclined upward from the side away from the hinged connection between the fixed plate 1 and the thigh support plate 2 to the side close to the hinged connection between the fixed plate 1 and the thigh support plate 2. A top wheel 14 is arranged in the slide groove 12. The radius of the top wheel 14 should be greater than the depth of the deepest end of the slide groove 12 (that is, the side of the slide groove 12 away from the hinged connection between the fixed plate 1 and the thigh support plate 2), and when the top wheel 14 is located at the deepest end of the slide groove 12, its upper surface should just touch the lower The lower surfaces of the thigh support plates 2 that have fallen to the horizontal position are pressed against each other. At this time, when the top wheel 14 rolls upward along the inclined surface of the bottom of the chute 12, the top wheel 14 will gradually rise, thereby pushing the thigh support plate 2 to slowly rotate upward. Conversely, when the top wheel 14 rolls downward along the inclined surface of the bottom of the chute 12, the top wheel 14 will gradually lower, thereby causing the thigh support plate 2 to slowly rotate downward. In addition, a push rod 13 is fixedly connected to the telescopic end of the electric telescopic rod 11, and the push rod 13 extends into the gap below the thigh support plate 2 and is connected to the top wheel 14, so that the top wheel 14 can be driven to roll forward and backward along the chute 12 through the electric telescopic rod 11.
[0023] A switch slot 15 is provided on the inner side plate of the thigh support plate 2 on the same side as the slide slot 12, and an upper push switch 16 for controlling the extension of the electric telescopic rod 11 and a lower push switch 17 for controlling the shortening of the electric telescopic rod 11 are provided in the switch slot 15. The upper push switch 16 and the lower push switch 17 are symmetrically arranged on the upper and lower sides of the switch slot 15, and a pressure rod 18 extending horizontally between the upper push switch 16 and the lower push switch 17 is provided on the thigh support plate 2 on the other side opposite to the switch slot 15.
[0024] Furthermore, positioning guide wheels 19 should be respectively provided on the relatively inner plate edges of the two calf support plates 3, the positioning guide wheels 19 are located at the end of the calf support plate 3 close to the foot support plate 4, and a positioning guide groove 20 adapted to the card holder positioning guide wheel 19 is opened on the fixed plate 1, the positioning guide groove 20 is opened along the length direction of the calf support plate 3, and the groove depth is less than the radius of the positioning guide wheel 19. When the end of the calf support plate 3 close to the thigh support plate 2 is lifted upward, the end of the calf support plate 3 away from the thigh support plate 2 can slide stably along the positioning guide groove 20, thereby preventing the plate edge of the calf support plate 3 from rubbing against the upper surface of the fixed plate 1 with great force.
[0025] Furthermore, in order to achieve massage stimulation on the patient's affected lower limb, an electric pulse massager 21 can be arranged on the fixing plate 1 (the electric pulse massager 21 can adopt a dual-frequency pulse massager of model LY-518 produced by Foshan Lingyuan Medical Technology Co., Ltd.), and massage electrode patches 22 can be arranged on the thigh support plate 2 and the calf support plate 3 on the same side as the slide groove 12. The control input end of the massage electrode patch 22 is electrically connected to the control output end of the electric pulse massager 21, so that the massage electrode patch 22 can be attached to the patient's affected lower limb for massage stimulation.
[0026] When in use, the two lower limbs of the patient in supine position are fixed on the two sets of leg supports respectively, and it is noted that the affected lower limb is fixed on the leg support on the same side as the slide groove 12.
[0027] When you need to do toe-curling exercises, the toe-curling action of the healthy lower limb can drive the affected lower limb to curl its toe synchronously.
[0028] When it is necessary to perform knee flexion exercise, the corresponding thigh support plate 2 can be rotated upward by the knee flexion action of the healthy lower limb, thereby driving the pressure rod 18 to move upward to press the upper push switch 16, so that the electric telescopic rod 11 is controlled to extend toward the hinged side of the fixed plate 1 and the thigh support plate 2, thereby driving the top wheel 14 to roll toward the direction close to the patient's body; during the rolling process of the top wheel 14, its upper surface always keeps contact with the lower surface of the thigh support plate 2, and at this time, as the bottom of the chute 12 gradually tilts upward, the top wheel 14 will also move upward continuously, thereby pushing the thigh support plate 2 of the affected lower limb to rotate upward, and realizing the synchronous upward rotation of the two thigh support plates 2. At the same time, since the calf support plate 3 is hinged with the thigh support plate 2, the end of the calf support plate 3 close to the patient's body will be lifted up together, and the end of the calf support plate 3 away from the patient's body will slide toward the patient's body under the cooperation of the positioning guide wheel 19 and the positioning guide groove 20, so that the patient's legs are in a knee flexion posture. On the contrary, when the healthy lower limb moves downward and is flattened, the pressure rod 18 moves downward and presses the press switch 17, so that the electric telescopic rod 11 can be controlled to shorten away from the hinged side of the fixing plate 1 and the thigh support plate 2, driving the top wheel 14 to roll away from the patient's body, thereby slowly flattening the affected lower limb.
[0029] When leg-lifting exercise is required, the thigh support plate 2 and the calf support plate 3 are fixedly connected by a locking mechanism. At this time, the leg-lifting action of the healthy lower limb can control the synchronous leg-lifting of the affected lower limb, and the horizontal laying action of the healthy lower limb can control the synchronous horizontal laying of the affected lower limb.
[0030] The entire training rehabilitation device can utilize the active movement of the healthy lower limb to control the synchronous movement of the affected lower limb, so that the affected lower limb can complete exercise movements such as hooking the foot, bending the knee and raising the leg together with the healthy lower limb, realizing synchronous interactive perception training of bilateral lower limbs, facilitating the training of deep sensation of both sides of the limbs, and increasing the coordination ability of bilateral limbs of patients, which is of great significance for the coordinated movement of limbs after surgery.
