Description

Technical Field

[0001] This application relates to the field of medical rehabilitation devices, and in particular to a guided walking aid. Background Technology

[0002] Currently, the main functions of walking aids are to replace support, maintain balance, assist walking, and increase muscle strength. They are suitable for situations where the affected limb is weak due to hemiplegia or paraplegia, or where the lower limbs are too weak to support weight well, or where limbs or joints cannot bear weight due to surgery or other reasons.

[0003] When using a walking aid, regular rehabilitation training should be conducted under the guidance of a rehabilitation physician. When patients first begin using a walking aid, they may not be able to use it according to the instructions due to different personal habits. Utility Model Content

[0004] This application provides a walking aid that guides the patient's step sequence and foot placement.

[0005] This application provides a walking aid, including a support frame, a lateral guide, and a vertical guide. The lateral guide includes a lateral elastic portion and a traction portion. One end of the lateral elastic portion is fixed to the support frame, and the other end is fixedly connected to the traction portion. The horizontal distance between the two ends of the lateral elastic portion can increase or decrease within a set range. When the horizontal distance between the two ends of the lateral elastic portion increases, the lateral elastic portion applies a forward pulling force to the traction portion. The traction portion is used for a detachable fixed connection to the affected leg. The vertical guide includes a vertical elastic portion and a connecting portion. One end of the vertical elastic portion is fixed to the support frame, and the other end is fixedly connected to the connecting portion. The vertical distance between the two ends of the elastic portion can increase or decrease within a set range. When the vertical distance between the two ends of the vertical elastic portion increases, the vertical elastic portion applies an upward pulling force to the traction portion. The connecting portion is used for a detachable fixed connection to the foot of the affected leg, and the connection position corresponds to the forefoot of the affected leg.

[0006] In the above technical solution, after the support frame is moved forward and placed stably, the lateral elastic part applies a forward pulling force to the traction part, and the traction part applies a forward pulling force to the affected leg. At this time, when the patient steps forward, he can naturally step out with the affected leg first, and then step out with the healthy leg, thereby guiding the patient's leg-stepping sequence.

[0007] When the affected leg falls, the distance between the foot of the walker and the support frame increases along the height direction, the tension of the vertical elastic part on the connecting part increases, and the connecting part applies an upward pulling force to the forefoot of the affected leg. When the patient's foot lands on the ground, it can naturally land first on the heel and then on the forefoot, thus guiding the patient's foot landing method.

[0008] Optionally, the lateral elastic part includes a lateral elastic cord, and the traction part includes a Velcro fastener, which is fixed to the lateral elastic cord.

[0009] Optionally, the vertical elastic part includes a vertical elastic cord, and the connecting part includes a foot sleeve, which is used to fit over the patient's forefoot and is fixedly connected to the vertical elastic cord.

[0010] Optionally, the connecting part also includes a connecting strap, the two ends of which are fixedly connected to the two ends of the foot sleeve, and the middle of the connecting strap is used to fit over the back of the affected leg.

[0011] Optionally, the support frame is provided with a transverse positioning part, which is fixedly connected to the transverse elastic part, and is used to fix one end of the transverse elastic part connected to the support frame at a first position or a second position. The first position and the second position are two positions spaced apart along the left and right direction.

[0012] Optionally, the lateral positioning part includes two first annular grooves disposed on the support frame, the two first annular grooves being spaced apart in the left-right direction.

[0013] Optionally, the support frame is provided with a vertical positioning part, which is fixedly connected to the vertical elastic part, and is used to fix one end of the vertical elastic part connected to the support frame in the third position or the fourth position. The third position and the fourth position are two positions that are spaced apart along the left and right direction.

[0014] Optionally, the vertical positioning part includes two second annular grooves disposed on the support frame, the two second annular grooves being spaced apart in the left-right direction.

[0015] Optionally, the support frame includes legs, hand supports, a front crossbar, and an upper crossbar; there are two hand supports; there are four legs, each fixed to one end of the two hand supports; the two ends of the front crossbar are fixedly connected to the two legs; the two ends of the upper crossbar are fixedly connected to the two hand supports; the lateral guide is fixed to the front crossbar, and the vertical guide is fixed to the upper crossbar.

[0016] In the above technical solution, the connecting strap can improve the stability of the foot sleeve on the forefoot and reduce the occurrence of the foot sleeve coming off the foot. Attached Figure Description

Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0020] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] This application discloses a guided walking aid. When using the walking aid, place it directly in front of the patient, hold the walking aid firmly with both hands and stand steadily. The affected leg steps out first, with the heel landing on the back leg of the walking aid. The healthy leg then steps out and is at the same level as the affected leg. After moving the walking aid forward, repeat the above actions.

[0023] When using a walking aid, patients need to pay attention to stepping out with the affected leg first, and the heel of the affected leg should land first. Medical staff need to teach them this. When patients first start using a guided walking aid, due to personal habits, they may step out with the healthy leg first and land on the ball of their foot. This application discloses a guided walking aid that, when used by patients, will more naturally lead them to step out with the affected leg first and land on the heel of the affected leg first.

[0024] A walking aid includes a support frame, a lateral guide, and a vertical guide.

[0025] The lateral guide includes a lateral elastic part and a traction part. One end of the lateral elastic part is fixed to the support frame, and the other end is fixedly connected to the traction part. The horizontal distance between the two ends of the lateral elastic part can be increased or decreased within a set range. When the horizontal distance between the two ends of the lateral elastic part increases, the lateral elastic part applies a forward pulling force to the traction part. The traction part is used for a detachable fixed connection with the affected leg.

[0026] The vertical guide includes a vertical elastic part and a connecting part. One end of the vertical elastic part is fixed to the support frame, and the other end is fixedly connected to the connecting part. The distance between the two ends of the vertical elastic part in the vertical direction can be increased or decreased within a set range. When the distance between the two ends of the vertical elastic part in the vertical direction increases, the vertical elastic part applies an upward pulling force to the traction part. The connecting part is used for a detachable fixed connection with the foot of the affected leg, and the connection position corresponds to the forefoot of the affected leg.

[0027] For ease of explanation, a first direction, a second direction, and a third direction are defined. The first direction is the front-to-back direction, which is the direction in which a person stands on the support frame and faces, and is also the front direction described in this embodiment. The second direction is the left-to-right direction, which is the left-to-right direction in which a person stands on the support frame. The third direction is the up-down direction, which is the up-down direction in which a person stands on the support frame. In the accompanying drawings, the first direction is represented by the X direction, the second direction by the Y direction, and the third direction by the Z direction.

[0028] Reference Figure 1 A guided walking aid includes a support frame 1, a lateral guide 2, and a vertical guide 3. The support frame 1 has legs and handrails for patient use, and its specific structure is similar to that of a conventional walking aid, which will be described in detail later. The lateral guide 2 connects to the affected leg, applying a forward pulling force to the affected leg when the distance between the support frame 1 and the patient exceeds a set distance, causing the affected leg to tend forward. The vertical guide 3 connects to the forefoot of the affected leg, applying an upward pulling force to the forefoot when the foot of the affected leg is close to the ground, causing the forefoot of the affected leg to tend upward.

[0029] The lateral guide 2 includes a lateral elastic part 21 and a traction part 22. One end of the lateral elastic part 21 is fixed to the support frame 1, and the other end is fixedly connected to the traction part 22. The horizontal distance between the two ends of the lateral elastic part 21 can be increased or decreased within a set range. When the horizontal distance between the two ends of the lateral elastic part 21 increases, the lateral elastic part 21 applies a pulling force to the traction part 22 in a first direction toward the support frame 1. The traction part 22 is used for a detachable fixed connection with the affected leg.

[0030] Specifically, the transverse elastic part 21 is a component capable of elastic deformation. When the distance between the two ends of the transverse elastic part 21 is greater than the distance between the two ends of the transverse elastic part 21 in its natural state, the elastic force generated by the transverse elastic part 21 increases as the distance between the two ends of the transverse elastic part 21 gradually increases. It should be noted that the distance between the two ends of the transverse elastic part 21 should not exceed the maximum design distance to avoid damage caused by irreversible deformation of the transverse elastic part 21.

[0031] The traction part 22 is connected to the affected leg. Depending on the patient's condition, the traction part 22 can be connected to the patient's thigh, calf, or knee. For example, the traction part 22 is a Velcro fastener, which is fixedly connected to the transverse elastic part 21. After the Velcro is wrapped around the affected leg and fastened, the connection between the traction part 22 and the affected leg is achieved.

[0032] One end of the lateral elastic part 21 is fixed to the support frame 1, and the other end is fixedly connected to the traction part 22. When the patient stands with both legs side by side, the distance between the lateral elastic part 21 and the support frame 1 along the first direction is the shortest, and the lateral elastic part 21 is in a relaxed state. The distance between the two ends of the lateral elastic part 21 is less than the distance between the two ends of the lateral elastic part 21 in its natural state. When the support frame 1 moves forward, the distance between the two ends of the lateral elastic part 21 increases, and after exceeding the distance between the two ends of the lateral elastic part 21 in its natural state, it further increases, and the lateral elastic part 21 applies a forward pulling force to the traction part 22.

[0033] It should be noted that when the lateral elastic part 21 applies a forward pulling force to the traction part 22, the lateral elastic part 21 can be in a horizontal state. In this case, the elastic force generated by the lateral elastic part 21 is the forward pulling force applied by the lateral elastic part 21 to the traction part 22. The lateral elastic part 21 can also be in an inclined state. In this case, the horizontal component of the elastic force generated by the lateral elastic part 21 is the forward pulling force applied by the lateral elastic part 21 to the traction part 22. In this embodiment, when the support frame 1 moves forward and is placed on the ground, the lateral elastic part 21 is in an inclined state with an inclination angle of no more than 30°.

[0034] Because the walking aid requires the support frame 1 to be moved forward and stabilized before the patient takes a step, and the affected leg must step forward first, the lateral elastic part 21, after the support frame 1 is moved forward and stabilized, applies a forward pulling force to the traction part 22, which in turn applies a forward pulling force to the affected leg. Therefore, when the patient steps forward, the affected leg naturally steps forward first, followed by the healthy leg, thus guiding the patient's leg-stepping sequence.

[0035] The vertical guide 3 includes a vertical elastic part 31 and a connecting part 32. One end of the vertical elastic part 31 is fixed to the support frame 1, and the other end is fixedly connected to the connecting part 32. The distance between the two ends of the vertical elastic part 31 in the vertical direction can be increased or decreased within a set range. When the distance between the two ends of the vertical elastic part 31 in the vertical direction increases, the vertical elastic part 31 applies an upward pulling force to the traction part 22.

[0036] The connecting part 32 is used for a detachable fixed connection with the foot of the leg to be practiced by the patient, and the connection position corresponds to the forefoot of the affected leg.

[0037] Specifically, the vertical elastic part 31 is a component capable of elastic deformation. When the distance between the two ends of the vertical elastic part 31 is greater than the distance between the two ends of the vertical elastic part 31 in its natural state, the elastic force generated by the vertical elastic part 31 gradually increases as the distance between the two ends of the vertical elastic part 31 gradually increases. The distance between the two ends of the vertical elastic part 31 should not exceed the maximum design distance to avoid damage caused by irreversible deformation of the vertical elastic part 31.

[0038] The connecting part 32 connects to the forefoot of the affected leg. In this embodiment, the connecting part 32 is fitted onto the forefoot of the shoe. Specific implementation details will be provided later. In another embodiment, the connecting part 32 can be attached to the front of the shoe via a flexible cord.

[0039] One end of the vertical elastic part 31 is fixed to the support frame 1, and the other end is fixedly connected to the connecting part 32. When the patient is standing, the distance between the patient's feet and the support frame 1 along the height direction is the longest, and the vertical elastic part 31 is in a tensioned state.

[0040] During the patient's forward movement, when the affected leg is raised, the distance between the patient's foot and the support frame 1 decreases along the height direction, and the tension of the vertical elastic part 31 on the connecting part 32 decreases. When the affected leg is lowered, the distance between the patient's foot and the support frame 1 increases along the height direction, and the tension of the vertical elastic part 31 on the connecting part 32 increases.

[0041] Because the connecting part 32 applies an upward pulling force to the forefoot of the affected leg, when the patient's foot lands on the ground, the heel naturally lands first, followed by the forefoot, thus guiding the patient's foot landing method.

[0042] It should be noted that when the vertical elastic part 31 applies an upward pulling force to the connecting part 32, the vertical elastic part 31 can be in a vertical state, in which case the elastic force generated by the vertical elastic part 31 is the upward pulling force applied by the vertical elastic part 31 to the connecting part 32. The vertical elastic part 31 can also be in an inclined state, in which case the vertical component of the elastic force generated by the vertical elastic part 31 is the upward pulling force applied by the vertical elastic part 31 to the connecting part 32. In this embodiment, the vertical elastic part 31 applies an obliquely upward pulling force to the connecting part 32.

[0043] At the same time, since the vertical elastic part 31 applies an upward pulling force to the foot of the affected leg through the connecting part 32, the setting of the vertical elastic part 31 can also reduce the burden when the affected leg is lifted, which helps the early exercise of the affected leg.

[0044] Reference Figure 1 As an alternative, the lateral elastic part 21 includes a lateral elastic cord, and the traction part 22 includes a Velcro fastener, which is fixed to the lateral elastic cord.

[0045] Specifically, the transverse elastic rope is an ordinary elastic rope that can resist tension to a certain extent and convert deformation into elastic potential energy, including but not limited to at least one of rubber elastic rope, nylon elastic rope or polyester elastic rope.

[0046] Hook and loop fasteners are also called hook and loop fasteners. One side of the material is made of fine, soft fibers, while the other side is made of stiffer, hooked bristles. When the two sides are pressed together, they stick together to form a reliable connection.

[0047] One end of the horizontal elastic cord is fixed to the support frame 1, and the other end is fixedly connected to the Velcro. The Velcro is used for a detachable fixed connection with the affected leg.

[0048] In another embodiment, the lateral elastic part 21 includes a lateral tension spring and a connecting rope. One end of the lateral tension spring is fixed to the support frame 1, and the other end is fixedly connected to the connecting rope, which is fixedly connected to Velcro.

[0049] In another embodiment, the traction part 22 is a flexible ring that can be fitted onto the affected leg; or the traction part 22 is two flexible ropes, one end of which is fixedly connected to the transverse elastic part 21, and the other end is tied tightly behind the affected leg.

[0050] Reference Figure 1 As an alternative, the vertical elastic part 31 includes a vertical elastic rope, and the connecting part 32 includes a foot sleeve 321, which is used to be fitted onto the patient's forefoot and is fixedly connected to the vertical elastic rope.

[0051] Specifically, vertical elastic rope is a common elastic rope that can resist tension to a certain extent and convert deformation into elastic potential energy, including but not limited to at least one of rubber elastic rope, nylon elastic rope or polyester elastic rope.

[0052] The foot sleeve 321 is a U-shaped silicone sleeve with an opening area larger than the bottom area. The foot sleeve 321 can be fitted onto the forefoot of the affected leg.

[0053] Reference Figure 1 As an alternative, the connecting part 32 also includes a connecting strap 322, the two ends of which are fixedly connected to the two ends of the foot sleeve 321, and the middle of the connecting strap 322 is used to be fitted onto the back of the patient's foot.

[0054] Specifically, the connecting strap 322 is a nylon strap, and both ends of the connecting strap 322 are fixed to the foot sleeve 321. When in use, the foot sleeve 321 is placed on the forefoot of the affected leg, and the connecting strap 322 connects to the foot sleeve 321 on the left and right sides of the forefoot. The connecting strap 322 is U-shaped, with its middle located at the ankle. In another embodiment, the connecting strap 322 is an elastic band.

[0055] The connecting strap 322 can improve the stability of the foot sleeve 321 fixed on the forefoot and reduce the occurrence of the foot sleeve 321 detaching from the foot.

[0056] Reference Figure 1 As an optional solution, the support frame 1 includes legs 13, hand rests 14, a front crossbar 15, and an upper crossbar 16.

[0057] There are two hand supports 14. There are four feet 13, which are fixed to the two ends of the two hand supports 14 respectively.

[0058] The two ends of the front crossbar 15 are fixedly connected to the two support legs 13 respectively; the two ends of the upper crossbar 16 are fixedly connected to the two hand supports 14 respectively.

[0059] The lateral guide 2 is fixed to the front crossbar 15, and the vertical guide 3 is fixed to the upper crossbar 16.

[0060] Specifically, the hand support 14 is a rod bent downward at both ends. Two hand supports 14 are spaced apart along the second direction. The upper ends of four legs 13 are fixed to the two ends of the hand support 14 to support the two hand supports 14.

[0061] The length of the front crossbar 15 is set along the second direction, and both ends of the front crossbar 15 are fixedly connected to two support legs 13, which are respectively fixed to two hand supports 14. The front crossbar 15 and the support legs 13 can be fixed by welding, bolting or other fixing methods.

[0062] Furthermore, the front crossbar 15 is detachably fixed to the support leg 13 at at least two heights. The front crossbar 15 can be fixed to the support leg 13 at at least two positions spaced apart along the height direction. Depending on the condition of the affected leg, when it is the thigh, the front crossbar 15 is fixed at a higher position above the ground, and when it is the lower leg, the front crossbar 15 is fixed at a lower position above the ground.

[0063] The upper crossbar 16 is fixed at both ends to two hand supports 14 and is located above the front crossbar 15. The upper crossbar 16 and the hand supports 14 can be fixed by welding, bolting, or other methods.

[0064] Reference Figure 1 As an optional solution, the support frame 1 is provided with a transverse positioning part 11, which is fixedly connected to the transverse elastic part 21. The transverse positioning part 11 is used to fix one end of the transverse elastic part 21 connected to the support frame 1 at a first position or a second position. The first position and the second position are two positions that are spaced apart along the left and right direction.

[0065] Specifically, the lateral positioning part 11 is designed to be fixed in any of multiple positions on the support frame 1 to accommodate the needs of different patients. Specifically, two positions are provided on the front crossbar 15 at intervals along the left and right direction: a first position and a second position.

[0066] In this embodiment, the lateral positioning part 11 includes two grooves, the specific form of which will be described later. In another embodiment, the lateral positioning part 11 may be at least two through holes or positioning blocks spaced apart in the left-right direction.

[0067] When the lateral positioning part 11 fixes the lateral elastic part 21 in the first position or the second position, it corresponds to the use of the patient's left leg and right leg, respectively, thereby facilitating the patient's use.

[0068] The lateral positioning part 11 can restrict the end of the lateral elastic part 21 connected to the front crossbar 15 within the groove, preventing the lateral elastic part 21 from moving in the left and right direction on the front crossbar 15 and affecting its use.

[0069] Reference Figure 1 As an optional solution, the lateral positioning part 11 includes two first annular grooves 111 disposed on the support frame 1, and the two first annular grooves 111 are spaced apart in the left and right direction.

[0070] Specifically, the lateral positioning part 11 includes two first annular grooves 111 opened on the front crossbar 15. The first annular groove 111 is an annular groove. The width of the first annular groove 111 in the left-right direction is greater than the diameter of the lateral elastic part 21. The connection position between the lateral elastic part 21 and the support frame 1 is located in one of the grooves.

[0071] The first annular groove 111 has a simple structure, which facilitates the positioning and connection of the transverse elastic part 21. After the transverse elastic part 21 is connected in the first annular groove 111, the surface of the front crossbar 15 is relatively flat.

[0072] Reference Figure 1 As an optional solution, the support frame 1 is provided with a vertical positioning part 12, which is fixedly connected to the vertical elastic part 31. The vertical positioning part 12 is used to fix the end of the vertical elastic part 31 connected to the support frame 1 in the third position or the fourth position. The third position and the fourth position are two positions that are spaced apart along the left and right direction.

[0073] Specifically, the vertical positioning part 12 is designed to be fixed in any of multiple positions on the support frame 1 to accommodate the needs of different patients. Specifically, two positions are provided on the upper crossbar 16 at intervals along the left and right direction: a third position and a fourth position.

[0074] In this embodiment, the vertical positioning part 12 includes two grooves, the specific form of which will be described later. In another embodiment, the vertical positioning part 12 may be at least two through holes or positioning blocks spaced apart in the left-right direction.

[0075] When the vertical positioning part 12 fixes the vertical elastic part 31 in the third or fourth position, it corresponds to the use of the patient's left and right legs, respectively, thereby facilitating the patient's use.

[0076] The vertical positioning part 12 can restrict the end of the vertical elastic part 31 connected to the upper crossbar 16 within the groove, preventing the vertical elastic part 31 from moving in the left and right direction on the upper crossbar 16 and affecting its use.

[0077] Reference Figure 1 As an optional solution, the vertical positioning part 12 includes two second annular grooves 121 disposed on the support frame 1, and the two second annular grooves 121 are spaced apart in the left-right direction.

[0078] Specifically, the vertical positioning part 12 includes two second annular grooves 121 opened on the upper crossbar 16. The second annular grooves 121 are annular grooves. The width of the second annular grooves 121 in the left and right direction is greater than the diameter of the vertical elastic part 31. The connection position between the vertical elastic part 31 and the support frame 1 is located in one of the grooves.

[0079] The second annular groove 121 has a simple structure, which facilitates the positioning and connection of the vertical elastic part 31. After the vertical elastic part 31 is connected in the second annular groove 121, the surface of the upper crossbar 16 is relatively flat.
