Description

Technical Field

[0001] The utility model relates to the technical field of limb correctors, in particular to an adaptive foot support. Background Art

[0002] Some patients with brain trauma or stroke have symptoms such as foot drop or inversion. In order to treat these symptoms, ankle-foot orthoses, also known as foot supports, are usually used. However, in existing ankle-foot orthoses, the soft pads used to fit the patient's feet are usually fixed to the foot support shell by Velcro. This fixing method has some problems, such as the soft pads are easy to fall off or shift when walking.

[0003] Therefore, in order to solve these problems, it is necessary to improve the fixing method of the cushion. By adopting innovative designs, the cushion can be more firmly attached to the foot support shell to ensure that it will not fall off or shift easily. Through this improvement, patients can walk more stably and comfortably, and can comprehensively and effectively treat diseases such as foot drop or foot inversion, thereby improving the treatment effect and the patient's quality of life.

[0004] For example, a foot support cushion fixing structure and ankle-foot orthosis with application number CN202222453456.6 has the following technical points: it includes a foot support shell, which is provided with a fixing slot; and a cushion body, which is provided with a fixing nail, and the fixing nail cooperates with the fixing slot to fix the cushion body to the inner wall surface of the foot support shell. A foot support portion for supporting the sole of the user's foot is formed at the bottom of the foot support shell, and an anterior tibial covering portion for covering the lower front end of the user's tibia is formed at the upper end, and two connecting portions are formed on the left and right sides to connect the foot support portion with the anterior tibial covering portion and cover the user's ankle. The cushion body includes an anterior tibial covering pad and two ankle covering pads, the anterior tibial covering pad is arranged corresponding to the anterior tibial covering portion, and the two ankle covering pads are arranged corresponding to the two connecting portions respectively. The upper and lower edges of the anterior tibial covering portion are respectively formed with at least two fixing slots, and the anterior tibial covering pad is correspondingly provided with at least four fixing nails; the front and rear edges of the connecting portion are respectively formed with at least one fixing slot, and the ankle covering pad is correspondingly provided with at least two fixing nails. The anterior tibial covering pad and the two ankle covering pads are integrally provided. The cushion body also includes an inflatable airbag, and the inflatable airbag also includes an inflation nozzle. An opening is formed in the foot support shell corresponding to the inflation nozzle. The opening is provided in the anterior tibial covering portion. A plurality of dividing grooves are vertically formed on the upper edge of the anterior tibial covering portion.

[0005] The inflatable airbag is mainly inflated and deflated through the inflation and exhaust nozzle connected thereto. When completing the inflation action, the foot support cannot be inflated through its own structure, and must be done with the help of external force. That is, after the inflatable ball is connected to the inflation and exhaust nozzle, the inflatable ball is repeatedly blown up by manpower to complete the inflation of the inflatable airbag by the inflatable ball. However, when going out, it is difficult to carry the inflatable ball with you, and the possibility of forgetting to bring it is higher. In this way, when going out, once the inflatable ball is not carried, and the foot support needs to be taken off and put on again, the foot support will inevitably not fit the shape of the human foot, causing the foot support to become loose when people wear it to walk.

[0006] Therefore, an adaptive foot support is proposed to solve or alleviate the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an adaptable foot rest, in which the air cap can be manually loosened to increase the gap between the air cap and the air nozzle, and the elastic energy stored in the elastic block is released, and the TPE layer fixed in the foot rest shell is used as the force point to push the other side of the TPE layer, so that air passes through the gap between the air cap and the air nozzle and enters the airbag lining. The airbag lining is thus inflated to fit the calf, ankle and instep of the human body and conform to the shape of the foot. No additional structure, such as auxiliary tools such as an inflating ball, is required to inflate the airbag lining in the foot rest, thus avoiding the problem of forgetting to bring the inflating ball, and bringing a more convenient use experience.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] An adaptable foot support, such as Figure 1 As shown, it includes a foot support shell 1 and an air bag lining 2 fixedly connected to the inner side thereof.

[0026] The airbag lining 2 includes a calf portion 21 , an ankle portion 22 , and a dorsum 23 which are bonded to the inner circumferential wall of the foot support shell 1 and are integrally formed.

[0027] A through groove is opened on the foot support shell 1, and the foot support shell 1 at the through groove is fixedly connected with a reinforcement ring 3, and the specific fixing method is hot melting. A connecting sleeve 41 is fixedly connected to one side of the foot support shell 1, and a plug-in 42 is detachably connected to the connecting sleeve 41. A Japanese-shaped buckle 5 is fixedly connected to the plug-in 42, and a connecting belt 6 is fixedly connected to the other side of the foot support shell 1. The end of the connecting belt 6 away from the foot support shell 1 is wrapped around the Japanese-shaped buckle 5.

[0028] like Figure 2 As shown, the airbag lining 2 is connected to an air valve 7 which is arranged through the foot support shell 1, specifically, it is arranged through a through groove, the air valve 7 can be opened and closed, the end of the air valve 7 away from the airbag lining 2 is connected to an air nozzle with an inner diameter smaller than the air valve 7, and the air nozzle is detachably connected to an air cap 8, and a plurality of annular anti-slip grooves 81 are provided on the outer peripheral wall of the air cap 8, the air nozzle is tubular, and its inner diameter is smaller than the inner diameter of the air valve 7, and an external thread is provided on the outer peripheral wall of the air cap 8, the air cap 8 is a cylindrical structure with one end closed and the other end open, and the inner peripheral wall of the air cap 8 is provided with an internal thread connected to the external thread, a connecting rod which passes through the air nozzle to the air valve 7 is fixedly connected to the inner top surface of the air cap 8, and the end of the connecting rod away from the air cap 8 is fixedly connected to a limiting plate, the outer diameter of the limiting plate is larger than the inner diameter of the air nozzle, the outer diameter of the connecting rod is smaller than the inner diameter of the air nozzle, and the length of the connecting rod is less than twice the length of the air nozzle.

[0029] like Figure 3As shown, the minimum inner diameter of the airbag lining 2 is less than 6 cm, and the maximum inner diameter of the airbag lining 2 is equal to the inner diameter of the foot support shell 1. The airbag lining 2 includes a TPE layer 24 located on the inner and outer sides, and a plurality of elastic blocks 25 fixedly connected between the inner and outer sides of the TPE layer 24. The spaces between adjacent elastic blocks 25 are interconnected. A plurality of air holes 251 penetrating the elastic blocks 25 are provided on the outer peripheral walls thereof, and the spaces between adjacent elastic blocks 25 are all connected through the air holes 251.

[0030] When people need to use the foot support, they can adopt two methods. One is to put the foot into the foot support first, and the other is to put the foot into the foot support after the airbag lining 2 is inflated.

[0031] Method 1:

[0032] When people need to use it, they first put the sole of the foot through the foot support shell 1 and wrap the connecting belt 6 around the outside of the calf, so that the connecting belt 6 drives the Japanese-shaped buckle 5 and the plug-in 42 to move, so that the plug-in 42 can be inserted into the connecting sleeve 41, and then people manually adjust the length of the connecting belt 6 passing through the Japanese-shaped buckle 5 so that the foot support can be tied to the calf of people.

[0033] Then, the air cap 8 is touched manually. When touching the air cap 8, the anti-slip pattern 81 can effectively increase the friction between the air cap 8 and the human hand, so that when people twist the air cap 8, the force can be transmitted more smoothly, and then the internal thread of the air cap 8 and the external thread on the air nozzle can be loosened, so that the gap between the air cap 8 and the air nozzle is gradually increased.

[0034] During this process, the air cover 8 can drive the connecting rod and the limiting plate to move together. Since the outer diameter of the limiting plate is larger than the inner diameter of the air nozzle, the outer diameter of the connecting rod is smaller than the inner diameter of the air nozzle, and the length of the connecting rod is less than twice the length of the air nozzle, the connecting rod will not block the air circulation of the air nozzle. In addition, when the air cover 8 attempts to separate from the air nozzle, the air cover 8 will be restricted by the limiting plate through the connecting rod and the connection between the air nozzle and the air valve 7, resulting in the air cover 8 being unable to separate from the air nozzle, thereby avoiding the rapid flow of air and the loss of the air cover 8 after separation from the air nozzle.

[0035] In this process, the elastic block 25 begins to enter the airbag lining 2, that is, the space in the airbag lining 2 is no longer blocked. In this way, the elastic block 25 uses the TPE layer 24 on one side fixed to the inner wall of the foot support shell 1 as a force point to push the TPE layer 24 on the other side, thereby increasing the distance between the TPE layers 24 on both sides, so that the external air can continuously enter the airbag lining 2. Since a plurality of air holes 251 are provided on the outer wall of the elastic block 25 to penetrate the elastic block 25, the spaces between adjacent elastic blocks 25 are connected through the air holes 251. The elastic deformation stiffness of 5 will not be too large, and the force generated when it undergoes elastic deformation or the force required to resist the elastic deformation will not be too large. After the airbag lining 2 hits people's calves, ankles and insteps, the elastic block 25 will stop recovering to its natural state, and when the TPE layer 24 pushed by it contacts people's calves, ankles and insteps, people's calves, ankles and insteps will not feel a more obvious pushing force. In this way, the air can fully fill the airbag lining 2, and at the same time, the airbag lining 2 can fully fit and wrap people's calves, ankles and insteps.

[0036] Method 2: first manually loosen the air cap 8 to make the airbag lining 2 swell and reach the maximum new change state, and then people put their feet into the foot support shell 1, so that people can squeeze the airbag lining 2 through the calf, ankle and instep, and the calf, ankle and instep respectively correspond to the calf part 21, ankle part 22, and instep 23 of the airbag lining 2, so that air can gradually leave the airbag lining 2 until the airbag lining 2 meets the requirements of fitting people's bodies.

[0037] Then tighten the gas cap 8 and the gas nozzle to prevent air leakage.

[0038] No matter it is through the first method or the second method, the inflation of the airbag in the foot support can be completed by using additional tools, that is, without using an inflatable ball, so that people can use the foot support more conveniently.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
