Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation exercise, in particular to a lower limb auxiliary exercise device for bedridden rehabilitation. Background Art

[0002] Spinal injuries can affect the body's ability to control the limbs, which leads to loss of the body's ability to move. Therefore, long-term bed rest is usually required in the early stages of treatment. Long-term bed rest can cause muscle atrophy in the body, which in turn makes it difficult for patients to recover after the treatment. Therefore, passive exercises are required for the patient's lower limbs during the period of bed rest. Passive exercises usually require the patient's family members to spend time and effort to move the patient's lower limbs, thereby reducing the degree of muscle atrophy.

[0003] In order to reduce the effort required by patients' families to assist them in exercising, devices have emerged that use connecting plates to lift the patient's lower limbs. For example, Chinese patent application number CN202321527953.4 can flexibly connect the support assembly between the adjustment box and the connecting component through a hinge hole and a hinge shaft structure. When the patient performs lower limb rehabilitation exercises, the first L-shaped leg swing frame and the second L-shaped leg swing frame flexibly connected between the adjustment box and the connecting component can be driven to open and close by controlling the drive box to run in the forward or reverse direction, thereby allowing the patient's lower limbs, including the knee joints, to perform stretching exercises for rehabilitation exercises.

[0004] This device for passive lower limb exercise performs passive exercise by lifting and moving the patient's lower limbs, i.e., legs. During the above-mentioned passive exercise process, the patient's lower limbs, i.e., legs, will affect the patient's waist and the parts above the waist to produce a certain degree of displacement. When the displacement amplitude of the patient's waist and the parts above the waist is too large, it will cause a greater impact on the patient's spine, thereby increasing the probability of secondary injury to the patient's spine. At the same time, rehabilitation exercise is performed through the displacement of the rigid first L-shaped leg swing frame and the second L-shaped leg swing frame, and the rigid material will cause its movement trajectory to be unique and unchanged, and thus the movement of exercising the patient's lower limbs cannot be changed. Therefore, some muscle groups of the patient's lower limbs cannot be fully exercised, thereby reducing the effect of the patient's rehabilitation exercise of the lower limbs. Utility Model Content

[0005] The utility model aims to provide a lower limb auxiliary exercise device for bedridden rehabilitation, which can assist the patient's family members to exercise the patient's lower limbs on the basis of limiting the patient's upper body to achieve a protective effect.

[0006] In order to solve the above technical problems, the specific solution adopted by the utility model is: a lower limb auxiliary exercise device for bedridden rehabilitation, comprising a winding shaft, two bearing plates distributed at the ends of the winding shaft for locating its rotation position, a power mechanism for driving the winding shaft to rotate, and a limit rod slidably arranged on the bearing plate on one side of the winding shaft;

[0007] A lifting ring for the patient's legs to pass through is provided between the two groups of the bearing plates, and the lifting ring is fixedly connected to a pulling rope wound around a reel;

[0008] The limit rod is used to limit the lifting of the patient's waist. Both ends of the limit rod are provided with sliding sleeves and special-shaped elastic blocks. The sliding sleeve is rotatably matched with the limit rod, and the sliding sleeve is slidably matched with the supporting plate on the corresponding side. The special-shaped elastic block is fixedly connected to the limit rod, and the special-shaped elastic block can be slidably matched with the positioning groove of the supporting plate on the corresponding side, and the special-shaped elastic block can be tightly pressed against the inner wall of the positioning groove for braking by rotating the limit rod.

[0009] As a further optimization of the lower limb auxiliary exercise device for bed rehabilitation of the utility model, the power mechanism includes a lever arm plate fixed to one end of the winding shaft, and a rotating column is fixed to the end of the lever arm plate away from the winding shaft.

[0010] As a further optimization of the lower limb auxiliary exercise device for bed rehabilitation of the utility model, the bearing plate is composed of two connecting rods whose ends are matched with the winding shaft gap, an insertion sleeve and a sleeve connecting ring are provided between the two connecting rods corresponding to the winding shaft, and a protrusion and a groove for positioning the angle at the connection of the two connecting rods are provided between the sleeve connecting gap between the insertion sleeve and the sleeve connecting ring.

[0011] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, an anti-slip pad is fixedly connected to the bottom of the bearing plate.

[0012] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, the length of the winding shaft is 300-800 mm, and the number of the hanging rings is 1-2.

[0013] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, an elastic sleeve is fixedly connected to the outer peripheral surface at the center of the limit rod.

[0014] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, the special-shaped elastic block is made of rubber, and the special-shaped elastic block is rhombus-shaped.

[0015] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, the hanging ring is made of a rubber belt with air holes, and a Velcro is provided on the hanging ring.

[0016] As a further optimization of the lower limb auxiliary exercise device for bedridden rehabilitation of the utility model, both ends of the winding shaft are provided with limit plates.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model sets a limit rod to drive the sliding sleeve and the special-shaped elastic block to move. During the movement, the load-bearing plate and the positioning slot are used for restriction, so that the limit rod is moved to the patient's waist or thigh root. Then, the limit rod is rotated to make the two special-shaped elastic blocks rotate in the positioning slot. After the special-shaped elastic blocks rotate, they will be pressed against the inner wall of the positioning slot to limit the position of the limit rod on the corresponding load-bearing plate. In the above case, the load-bearing plate is pressed in accordance with the weight of the patient's lower limbs to keep the position of the load-bearing plate stable, and then when the patient's lower limbs, i.e., legs, are exercised, the patient's waist and the position above the waist are pressed and positioned, thereby reducing the extent of the patient's waist and the position above the waist being lifted in conjunction with each other during the passive exercise of the patient's lower limbs, thereby reducing the probability of secondary injury to the patient's spine.

[0019] The utility model connects the patient's lower limbs, i.e., legs, with a hanging ring, and cooperates with a power mechanism, a reel, and a pulling rope to perform passive exercise on the patient's lower limbs, i.e., legs. During the passive exercise, the flexible material of the pulling rope can change the movement trajectory of the patient's legs when the patient's lower limbs, i.e., legs, are passively trained, thereby performing a more comprehensive and sufficient exercise on the main muscle groups of the patient's lower limbs, i.e., legs.

[0024] The technical solution of the utility model is described below through two embodiments:

[0025] Example 1

[0026] like Figure 1 As shown, this embodiment includes a reel 6, a supporting plate 1 disposed at both ends of the reel 6, a power mechanism 8 for driving the reel 6, and a limiting rod 3 disposed on the side of the reel 6 facing the patient's trunk.

[0027] The bearing plate 1 is composed of two connecting rods with clearances between the two ends and the winding shaft 6. The two connecting rods form a triangle with the bed placement surface, thereby maintaining the stability of the rotation position of the winding shaft 6. Figure 3 As shown, two connecting rods are respectively fixedly connected with an insert sleeve 9 and a sleeve ring 7 at the winding shaft 6. The insert sleeve 9 is an outer gear ring, and the sleeve ring 7 is an inner gear ring. After the insert sleeve 9 and the sleeve ring 7 are sleeved, the gap between the two is a matching protrusion and groove. After the insert sleeve 9 with an outer gear ring shape and the sleeve ring 7 with an inner gear ring shape are sleeved, the two connecting rods constituting the bearing plate 1 and the bed placement surface will form a stable triangle to stably support the rotation position of the winding shaft 6. When it is necessary to adjust the height position of the winding shaft 6 rotation, the two connecting plates can be slid on the winding shaft 6, and then the insert sleeve 9 and the sleeve ring 7 are separated, so as to adjust the angle between the two connecting rods toward the winding shaft 6, that is, adjust the height position of the winding shaft 6 rotation. After the adjustment is completed, the insert sleeve 9 and the sleeve ring 7 can be plugged and reset, so as to realize the positioning of the rotation position of the winding shaft 6, and it can also be convenient for the patient's family to fold and store. The carrying plate 1 in this embodiment may also be composed of two connecting rods with fixed ends, and the two fixed ends of the connecting rods are matched with the winding shaft 6 through bearings.

[0028] Both ends of the limit rod 3 are provided with a sliding sleeve 4, and a special-shaped elastic block 5 is arranged inside the sliding sleeve 4. The special-shaped elastic block 5 is made of rubber, and the special-shaped elastic block 5 is rhombus-shaped. The sliding sleeve 4 is slidably connected to the support plate 1 facing the patient's torso side, and the special-shaped elastic block 5 is slidably connected to the positioning slide 2 provided on the corresponding support plate 1, and an anti-skid pad 101 is fixed to the bottom of the support plate 1. The anti-skid pad 101 cooperates with the weight of the patient's lower limbs to position the support plate 1 on the bed placement surface. After the position of the support plate 1 is positioned, the patient's family can move the limit rod 3 to slide on the corresponding support plate 1. After the limit rod 3 moves to the vicinity of the patient's leg root, the limit rod 3 can be rotated to rotate the two special-shaped elastic blocks 5 to tightly press against the inner wall of the positioning slide 2 for braking. Thereby, the limit rod 3 is moved to the upper end of the patient's thigh root to limit the lifting range of the patient's waist and the position above the waist, thereby reducing the lifting range of the patient's waist and the body above the waist caused by the passive exercise linkage during the passive exercise, that is, reducing the probability of secondary spinal injury caused by the impact on the spine due to excessive lifting of the patient's waist and the position above the waist.

[0029] An elastic sleeve 301 is fixedly connected to the outer peripheral surface at the center of the limit rod 3. The elastic sleeve 301 is made of sponge material, and thus can prevent slipping to a certain extent to assist the patient's family members to rotate the limit rod 3. At the same time, it can also reduce the discomfort caused to the patient by the material, i.e., hardness or temperature of the limit rod 3 when the limit rod 3 restricts the patient to a certain extent.

[0030] The power mechanism 8 includes a lever plate 801 fixedly connected to one end of the reel 6, and a rotating column 802 is fixed to the end of the lever plate 801 away from the reel 6. The rotating column 802 can assist the patient's family members to use the longer lever arm formed by the lever plate 801 to rotate the reel 6 with less effort.

[0031] A lifting ring 603 for connecting the patient's lower limbs, i.e., legs, is provided between the two bearing plates 1. The lifting ring 603 is fixedly connected to a pulling rope 602 wound on a reel 6. The reel 6 is 500 mm long and has one lifting ring 603, so that the patient's family can passively exercise the patient's lower limbs, i.e., legs one by one. The flexible structure of the pulling rope 602 can be used to rotate the reel 6 to reel in the pulling rope 602 when the lifting ring 603 is placed at different positions of the patient's lower limbs, i.e., legs, in cooperation with the power input of the power mechanism 8, so that different exercise movements are performed on the patient's lower limbs, i.e., legs, i.e., passive exercises are performed with different motion trajectories. For example, the lifting ring 603 is placed at the knee position of the patient's lower limbs, i.e., legs, to perform bending movement exercises on the patient's lower limbs, i.e., legs, so as to achieve full exercise of the joint activities of the patient's lower limbs, i.e., legs and thigh muscle groups. At the same time, the lifting ring 603 can be placed at the ankle position of the patient's lower limbs, i.e., the leg, to exercise the patient's lower limbs, i.e., the leg, to lift the leg as a whole, thereby achieving full exercise of the patient's lower limbs, i.e., the leg calf muscle group and the thigh root joint. The two sides of the winding shaft 6 in the length direction are fixedly connected to the limiting disk 601, and the setting of the limiting disk 601 can limit the slippage and separation of the pulling rope 602 from the winding shaft 6. The setting of the two limiting disks 601, the power mechanism 8 and the limiting disk can limit the sliding amount of the connecting rod, thereby reducing the probability of the connecting rod and the winding shaft 6 separating.

[0032] The lifting ring 603 is made of a rubber band with air holes, and a Velcro 604 is provided on the lifting ring 603. The Velcro 604 can make the lifting ring 603 open or close, and then connect with different positions of the patient's lower limbs, i.e., legs, under the condition of adjustable tension, so as to realize passive exercise of different movements of the patient's lower limbs, i.e., legs, under the condition of appropriate tightening force. The lifting ring 603 can also be connected to the patient's lower limbs, i.e., legs, without the patient's family members lifting the patient's lower limbs, i.e., legs significantly, so as to further reduce the workload of the patient's family members. When the patient's lower limbs, i.e., legs, are passively exercised, the lifting ring 603 made of a rubber band with air holes will be used to maintain good air permeability during the passive exercise of the patient's lower limbs, i.e., legs, so as to maintain the comfort of the patient's lower limbs, i.e., legs, during the passive exercise.

[0033] In this embodiment, the special-shaped elastic block 5 can be replaced with a disc-shaped one with two centrally symmetrical protrusions on the surface, and the protrusions are rubber blocks, which can slide in the positioning chute 2 under normal conditions, and can be braked by pressing against the inner wall of the positioning chute 2 after rotation. The protrusion on the outer side of the insertion sleeve 9 can be replaced with a wear-resistant ring with a friction surface, and the groove on the inner side of the sleeve ring 7 can be replaced with a wear-resistant sleeve that presses against the wear-resistant ring and has a friction surface on the inner wall. It can be plugged in and out to adjust the angle between the upper ends of the two connecting rods, and can also achieve the function of sleeve positioning to stabilize the angle between the upper ends of the two connecting rods.

[0034] Example 2

[0035] This embodiment is based on the embodiment 1, the length of the reel 6 and the number of the hanging rings 603 are changed, and its main structure is the same as that of the embodiment 1. Figure 2 As shown, the length of the winding shaft 6 is 800 mm, and two hanging rings 603 are provided. The longer winding shaft 6 can provide the patient's lower limbs, i.e., legs, with a larger exercise space during passive exercise, thereby reducing the probability of the patient's lower limbs, i.e., legs, colliding with the support plate 1 during passive exercise, i.e., improving the patient's comfort during passive exercise. The longer winding shaft 6 combined with the two hanging rings 603 can facilitate the patient's family members to exercise the patient's lower limbs, i.e., both legs, at the same time. After the length of the winding shaft 6 is changed, the length of the limit rod 3 will change synchronously, and the length of the limit rod 3 can be made greater than the patient's waist, so that the limit rod 3 can be placed at the corresponding position of the patient's waist or the root of the patient's thigh for use.
