Description

Technical Field

[0001] The present invention relates to the technical field of foot drop rehabilitation, and specifically, it is a functional sock for preventing foot drop and promoting rehabilitation. Background Art

[0002] Foot drop is caused by paralysis of the anterior and lateral muscle groups of the lower leg, while the posterior muscle group of the lower leg spasms and pulls, manifested as the inability to dorsiflex the foot. When walking, either drag the diseased foot, or lift the lower limb on that side higher, and when landing, the toes always touch the ground first.

[0003] When existing foot drop patients are undergoing rehabilitation training, they generally do it through exercise. The exercise rehabilitation training generally uses a corrector or a simple bandage. Such rehabilitation training devices have a single function and can only meet the use in one situation.

[0004] For example, the corrector can only be applicable to patients who can walk slowly, while the bandage can only be applicable to patients lying or sitting flat. The rehabilitation of patients is a process, and the existing rehabilitation training devices cannot meet the needs of patients in different scenarios.

[0005] In view of this problem, the present invention provides a new device to solve this problem. Summary of the Invention

[0006] In view of the above situation, in order to overcome the deficiencies of the prior art, the present invention provides a functional sock for preventing foot drop and promoting rehabilitation, effectively solving the technical problems that the existing foot drop rehabilitation training devices have a single function and cannot meet the rehabilitation training in multiple scenarios.

[0052] The front folding sock 23 and the rear folding sock 24 are respectively elastic stretch socks for wrapping the upper part of the foot.

[0053] In Embodiment 1:

[0054] When the patient is training in bed, the front folding sock 23 and the rear folding sock 24 are respectively wrapped around the front and rear of the foot.

[0055] When the patient is performing walking rehabilitation training, the front folding sock 23 and the rear folding sock 24 are respectively folded and telescoped towards the top wall 6 of the foot and the end wall 14 of the foot, and then rotated upwards and placed on the side wall of the leg to lock the leg so that the device does not loosen.

[0056] Embodiment 4: A front foot shaft 7 is coaxially connected with a front foot gear 26. The front foot gear 26 is placed on the inner side wall of the middle foot ring 2. The front foot gear 26 can mesh with a middle foot gear 27. The middle foot gear 27 is coaxially connected with a foot pulling wheel 28. A coil spring 31 is sleeved on the foot pulling wheel 28. A pull rope 29 is sleeved on the foot pulling wheel 28. The other end of the pull rope 29 is fixed with a pull ring 30. The pull ring 30 is placed at the top of the middle foot ring 2.

[0057] During specific use: In Embodiment 3 above, when the patient is performing bed training:

[0058] 1. The nylon belt 11 can be pulled upwards. The nylon belt 11 drives the front foot sock to rotate upwards, so that the front foot sock provides upward support for the front part of the foot.

[0059] 2. The pull ring 30 can also be pulled upwards. The pull ring 30 drives the foot pulling wheel 28 to rotate. The foot pulling wheel 28 coaxially drives the middle foot gear 27 to rotate. The middle foot gear 27 meshes with the front foot gear 26 to rotate. The front foot gear 26 drives the front foot shaft 7 to rotate upwards. The front foot shaft 7 drives the front foot sock to rotate upwards. After releasing the hand, the front foot sock returns to its original position. In this way, it reciprocates for rehabilitation training.

[0060] 3. When the pull ring 30 is pulled to a certain position, the pull ring 30 can be fixed at a suitable position.

[0061] Embodiment 5: A rear foot shaft 15 is coaxially connected with a rear foot gear 32 placed on the inner side wall of the middle foot ring 2. A "7"-shaped adjustment hole 33 is opened on the side wall of the middle foot ring 2. Three fixing holes 34 are opened beside the adjustment hole 33. The middle foot gear 27 is coaxially connected with a moving shaft 35. The moving shaft 35 can move in the adjustment hole 33. In the initial position, the moving shaft 35 is placed at the included angle in the middle of the adjustment hole 33. The moving shaft 35 is coaxially rotatably connected with a locking shaft 36.

[0062] When used specifically: In the second embodiment of the fourth embodiment above:

[0063] 1. When the movable shaft 35 is at the initial position, the midfoot gear 27 is meshed with the forefoot gear 26, and the forefoot sock can be rotated by pulling the pull ring 30.

[0064] 2. Move the movable shaft 35 laterally backward, and the movable shaft 35 drives the mid-foot gear 27 to move, and the mid-foot gear 27 is disengaged from the front foot gear 26. When the movable shaft 35 moves to the end, the mid-foot gear 27 is engaged with the rear foot gear 32, pulling the mid-foot gear 27. The mid-foot gear 27 drives the rear foot gear 32 to rotate, and the rear foot gear 32 drives the rear foot sock to rotate downward. The rear foot sock gives a downward pulling force to the rear part of the foot. After letting go, the rear foot sock is reset. When the rear foot sock rotates downward, it gives a downward rotational force to the rear part of the foot, thereby indirectly training the front part of the foot to rotate upward.

[0065] 3. Tilt the movable shaft 35 downward, and the movable shaft 35 drives the mid-foot gear 27 to move. The mid-foot gear 27 is engaged with the front foot gear 26 and the rear foot gear 32 at the same time. Pull the mid-foot gear 27, and the mid-foot gear 27 drives the front foot gear 26 and the rear foot gear 32 to rotate at the same time. The front foot gear 26 rotates upward, and the rear foot gear 32 rotates downward, so that the front part of the foot moves upward and the rear part of the foot moves downward, thereby exercising patients with foot drop.

[0066] 4. In another embodiment, the front folding sock 23 and the rear folding sock 24 are turned downward to wrap the forefoot airbag 9 and the rear foot airbag 17, and then the forefoot airbag 9 and the rear foot airbag 17 are inflated. The forefoot airbag 9 and the rear foot airbag 17 expand to the place where the front folding sock 23 and the rear folding sock 24 are attached to each other, forming a forefoot sock and a rear foot sock with hardness. When the patient is resting in bed, the forefoot sock and the rear foot sock can better support the foot.

[0067] In the sixth embodiment, the locking shaft 36 includes a short shaft 37 which is coaxially connected to the movable shaft 35 for rotation. A U-shaped telescopic shaft 38 is provided on the outer sliding sleeve of the short shaft 37. When the movable shaft 35 moves to a certain position, the telescopic shaft 38 is pressed into the short shaft 37, and then the end of the telescopic shaft 38 is placed in the fixing hole 34, thereby fixing the mid-foot gear 27. However, the mid-foot gear 27 can rotate. When the movable shaft 35 needs to be adjusted, the telescopic shaft 38 is pulled outward, and the telescopic shaft 38 is disengaged from the fixing hole 34, thereby adjusting the movable shaft 35.

[0068] Embodiment Seven: Inside the upper part of the rear foot gear 32, there is a locking gear 39. The locking gear 39 is slidably arranged on the side wall of the mid-foot ring 2 via a bending shaft 40. On both sides of the mid-foot ring 2, there are side baffles 41. The bending shaft 40 extends out of the side baffle 41. The end of the bending shaft 40 is threaded. A bottom support plate 42 is detachably installed on the two side baffles 41. On the upper surface of the side baffle 41, there is an installation hole 43. Inside the installation hole 43, there is a tilting shaft 44 rotatably arranged coaxially. At the other end of the tilting shaft 44, there is a threaded hole. The tilting shaft 44 is actually a lever rotating shaft. One end of the tilting shaft 44 is threadedly connected to the bending shaft 40. At the other end of the tilting shaft 44, there is a ratchet 45 installed inside the installation hole 43. At the hinge between the bending shaft 40 and the side baffle 41, there is a bearing seat, enabling the tilting shaft 44 to rotate, driving the ratchet 45 to rotate inside the installation hole 43. On the installation hole 43, there is a locking hole 46. The locking hole 46 is located on the upper surface of the side baffle 41 and is inclinedly communicated with the installation hole 43. Inside the locking hole 46, there is an inclined locking wire 47 threadedly installed.

[0069] During specific use:

[0070] When patients are undergoing rehabilitation training, they also adopt a standing posture:

[0071] 1. Move the moving shaft 35 downward so that the mid-foot gear 27 meshes with both the front foot gear 26 and the rear foot gear 32 simultaneously.

[0072] 2. Rotate the tilting shaft 44 on the side baffle 41, threadedly connect the end of the bending shaft 40 with the tilting shaft 44, making the bending shaft 40 and the tilting shaft 44 integrated, and then pull the side baffle 41 outwards.

[0073] 3. The locking gear 39 meshes with both the mid-foot gear 27 and the rear foot gear 32 simultaneously. The locking gear 39 locks the mid-foot gear 27 and the rear foot gear 32, making the front foot sock, the mid-foot sock, and the rear foot sock integrated.

[0074] 4. Rotate the tilting shaft 44 with the foot. The tilting shaft 44 drives the ratchet 45 to rotate. After adjusting to a suitable position, rotate the locking wire 47. The locking wire 47 enters inwards and gets stuck at the ratchet 45, making the ratchet 45 unable to rotate.

[0075] 5. After adjusting the angle of the tilting shaft 44, the front foot sock, the mid-foot sock, and the rear foot sock are at an inclined angle, and the patient can stand obliquely for rehabilitation training.

[0076] Another embodiment:

[0077] On the outer sides of the front foot wall 5 and the rear foot wall 13, there are waist-shaped holes. The ends of the front foot shaft 7 and the rear foot shaft 15 are placed inside the waist-shaped holes. According to the sizes of different people's feet, the positions of the front foot shaft 7 and the rear foot shaft 15 inside the waist-shaped holes can be adjusted and then fixed to change the wearing size of this device.

[0078] Another embodiment:

[0079] In the third embodiment of the fifth embodiment:

[0080] The front-foot sock, the middle-foot sock, and the rear-foot sock are connected as a whole. A rotating shaft is fixed at the lower end of the end-wall 14 of the foot.
