Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation braces, and more specifically, to an ankle joint rehabilitation brace. Background Technique

[0002] With the progress of medical technology, ankle joint rehabilitation braces, as important tools for assisting rehabilitation, play an increasingly important role in the recovery process of patients. However, there are still some significant defects in the design and function of existing ankle joint rehabilitation braces, especially in terms of wearing comfort and heat dissipation performance, which seriously affect the user experience and rehabilitation effect of patients.

[0003] Firstly, most existing ankle joint rehabilitation braces are mainly of the cloth strap type. Although this design provides support and protection to a certain extent, in the actual wearing process, patients often feel uncomfortable. The cloth strap design is prone to accumulating heat around the ankle joint, resulting in an increase in the temperature of the wearing area and bringing a stuffy feeling to patients. Especially in hot weather or when wearing for a long time, this discomfort is more obvious.

[0004] Secondly, existing ankle joint rehabilitation braces perform poorly in heat dissipation performance. Although some products attempt to solve the heat dissipation problem by opening heat dissipation holes, the effect is not ideal. This passive heat dissipation method cannot effectively discharge the accumulated heat, resulting in continuous heat accumulation inside the brace, further exacerbating the discomfort during wearing.

[0005] Therefore, in view of the above technical defect problems, it is necessary to propose an ankle joint rehabilitation brace. Content of the Utility Model

[0006] The purpose of the utility model is to propose an ankle joint rehabilitation brace aiming at the above defects.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0036] As shown in the attached Figure 1 to the attached Figure 6 figures: An ankle rehabilitation brace includes a sheath main body 1, an isolation layer 2, an air intake layer 3, an air delivery mechanism, and an air extraction mechanism. Among them, several groups of isolation layers 2 are provided and are arranged at intervals along the vertical direction on the inner side surface of the sheath main body 1, and several groups of air intake layers 3 are also provided and are arranged at intervals on the outer periphery of the sheath main body 1. At the same time, the air delivery mechanism and the air extraction mechanism are arranged outside the sheath main body 1, and the air intake layer 3 is in communication with the air delivery mechanism, while the air extraction mechanism is in communication with the air delivery mechanism.

[0037] In the above solution, through the design of the isolation layer 2, the inner end surface of the entire sheath can form a protrusion, so that when the sheath contacts the skin of the ankle joint, an interval space can be formed. The design of the air extraction mechanism and the air intake layer 3 allows the user to extract the heat generated during wearing inside the brace through the air intake layer 3 and the air delivery mechanism.

[0038] Furthermore, the sheath main body 1 is made of textile material, which can provide the required comfort and softness when contacting the skin. At the same time, a plurality of ventilation holes 32 are distributed from the outer side surface to the inner side of the sheath main body 1. The design of the ventilation holes 32 can meet the heat volatilization requirements, so that after the user wears it, passive heat dissipation can be carried out in combination with the ventilation holes 32.

[0039] Furthermore, both the isolation layer 2 and the air intake layer 3 are made of medical silicone material. This material has excellent elasticity and softness, can fit well with the skin on the ankle joint, and the silicone material has low heat conduction, which can reduce the problem of heat accumulation. In addition, it should be noted that in order to ensure the use effect of the isolation layer 2 and the air intake layer 3, medical silicone with moderate hardness needs to be selected. For example, if the isolation layer 2 is too soft, it cannot form an interval space well on the inner side surface of the brace. Similarly, if the air intake layer 3 is too soft, it is easily squeezed by the outside, resulting in the air intake layer 3 not being able to suck and transmit heat well.

[0040] At the same time, a channel is provided in the air intake layer 3, which is used to discharge the extracted hot air. At the same time, a plurality of air intake holes 31 are distributed along the inner side surface of the sheath body 1 at the left and right sides of the isolation layer 2, and these air intake holes 31 are connected with the channel in the air intake layer 3. This design enables the air intake holes 31 to be arranged in the interval space in the sheath body 1. Then, when the external air exhaust mechanism is exhausting air, the heat in the interval space can enter the channel through the air intake holes 31, and then be introduced into the gas transmission mechanism through the air intake layer 3.

[0041] Furthermore, the inner diameter of the air hole 32 should be smaller than the inner diameter of the air intake hole 31. This design enables the heat in the brace to be better extracted when the air intake hole 31 is located in the spacing space formed in the sheath.

[0042] Furthermore, the sheath body 1 is in a sock-shaped structure as a whole, and a first wearing opening 11 is opened at the lower end of the left side of the outer wall of the sheath body 1 and communicated with the inner end surface, and a second wearing opening 12 opposite to the first wearing opening 11 is opened at the bottom end surface of the sheath body 1, and then a notch 13 is vertically opened between the middle end of the top left side of the sheath body 1 and the first wearing opening 11. In this way, when in use, the sheath can be attached to the ankle in combination with the notch 13, and then the patient's foot can be inserted from the first wearing opening 11 to the second wearing opening 12, so that the entire sheath can be worn at the ankle position.

[0043] At the same time, at least one binding belt 14 is provided at the front and rear sides of the outer wall of the sheath body 1, and an adhesive layer, such as Velcro, is provided at the opposite end of the binding belt 14. When in use, the entire sheath can be tied to the ankle position by the binding belt 14, which can ensure the connection stability of the sheath. On the other hand, since the binding belt 14 is arranged at the peripheral position of the sheath, this design allows the user to selectively use some fixings to assist rehabilitation according to rehabilitation needs. For example, fixtures can be placed on both sides of the sheath, and these fixings are fitted with the patient's ankle position. After fitting, the fixings are pressed and fixed by the binding belt 14, which can ensure the stability of the fixings.

[0044] Furthermore, a plurality of mounting grooves 21 are spaced apart at one end (outer end face) of the isolation layer 2 facing the skin, and airbag layers 22 are mounted in the mounting grooves 21, and these airbag layers 22 are in an uninflated state. This design allows the airbag layer 22 to expand on the front side of the isolation layer 2 after being inflated, and allows the sheath body 1 to form an expanded state during expansion, which helps to enlarge the aperture of the air vents 32, thereby helping to enhance the passive heat dissipation effect of the sheath body 1.

[0045] like Figures 1 to 4As shown, in this embodiment, the air delivery mechanism is composed of a conduit 4 and an outer sleeve 43. The conduit 4 is provided with a first chamber 41 and a second chamber 42 that are separated from each other at the left and right inner sides respectively, and both the first chamber 41 and the second chamber 42 are communicated with the upper surface of the conduit 4. Inside the outer sleeve 43, two separated first branch pipes 44 and second branch pipes 45 are respectively arranged. One end of the first branch pipe 44 is communicated with the lower end inside the first chamber 41, and the other end is communicated with the airbag layer 22; one end of the second branch pipe 45 is communicated with the lower end inside the second chamber 42, and the other end is communicated with the suction layer 3. In this way, during use, external gas can be introduced into the airbag layer 22 through the first chamber 41 and the first branch pipe 44 for inflation; the arrangement of the second branch pipe 45 and the suction layer 3 allows the hot air extracted from the sheath to enter the first chamber 41.

[0046] Furthermore, a discharge pipe 6 is also communicatedly arranged along the right outer wall surface of the conduit 4 to the middle end of the inner wall of the second chamber 42. The discharge pipe 6 is used to discharge the extracted hot air. At the same time, at least one first air passage 61 is provided on the inner wall surface of the discharge pipe 6. The first air passage 61 has a U-shaped structure. The two end portions of the first air passage 61 are communicated with the inner wall surface of the discharge pipe 6, and the middle portion is away from the inner wall surface of the discharge pipe 6. This design facilitates the control of the gas flow direction, so that the first air passage 61 can only be used for discharging gas and cannot be used for suction.

[0047] Furthermore, at least one second air passage 62 is provided at the lower end of the inner wall of the second chamber 42. The second air passage 62 has a U-shaped structure. The two ends of the second air passage 62 are communicated with the inner wall surface of the second chamber 42, and the middle portion is away from the inner wall surface of the second chamber 42. This design can control the flow direction of the hot air extracted from the sheath, so that the second air passage 62 can only be used for suction and cannot be used for discharging gas.

[0048] As Figures 3 to 5 shown, in this embodiment, the air extraction mechanism is composed of a connection cap 5 and a balloon 51. The bottom of the connection cap 5 is provided with a cylindrical groove adapted to the conduit 4, and the connection cap 5 is hermetically and rotatably connected to the upper end of the top of the conduit 4 through the groove. The balloon 51 is arranged at the upper end of the top of the connection cap 5, and a connection head 52 is provided at the lower end of the balloon 51. The lower end of the connection head 52 is communicated with the top end surface of the groove inside the connection cap 5. In this way, during use, the balloon 51 can inhale and exhale through the connection head 52. When the balloon 51 is squeezed, the gas inside it can be ejected from the lower end of the connection head 52.

[0049] Meanwhile, the rotation radian of the connector 52 is adaptively set according to the set positions of the first chamber 41 and the second chamber 42. When the connection cap 5 drives the connector 52 to rotate, the bottom of the connector 52 can contact the tops of the first chamber 41 and the second chamber 42. This design enables the connection cap 5 to selectively inject the gas in the balloon 51 into the first chamber 41 or the second chamber 42 after rotation. When the gas extruded from the balloon 51 is injected into the first chamber 41, the balloon 51 can be inflated; when the balloon 51 returns from the squeezed state, negative pressure will be generated, and the heat in the spaced space within the sheath can be suctioned through the negative pressure. When suctioning, the air with heat can be inhaled into the second chamber 42 and the balloon 51. Subsequently, when the balloon 51 is squeezed again, the hot air extracted from the balloon 51 can be sent into the exhaust pipe 6 for discharge.

[0050] Furthermore, the top end surface of the inner wall of the groove is in contact with the top end surface of the catheter 4. This design ensures that there is no gap between the groove and the top end surface of the catheter 4. When the connection cap 5 drives the connector 52 away from the second chamber 42, the top of the second chamber 42 can be blocked by the top surface of the groove, preventing air leakage when the gas is injected into the first chamber 41 and the balloon layer 22, and ensuring the stable state of the balloon layer 22 after inflation. At the same time, the lower end surface of the connector 52 is in contact with the top end surface of the catheter 4, which can avoid air leakage during the gas flow when the connector 52 rotates to the position of the first chamber 41 or the second chamber 42.

[0051] Furthermore, an arc-shaped limiting groove 54 is formed on the inner wall surface of the groove of the connection cap 5, and a limiting block 55 is fixedly arranged at one end of the catheter 4 facing the limiting groove 54. One end of the limiting block 55 extends adaptively into the inner side of the limiting groove 54. During use, the rotation range of the connection cap 5 can be restricted by the limiting groove 54 and the limiting block 55, which can facilitate the alignment process of the connector 52 with the first chamber 41 and the second chamber 42. For example, when the connection cap 5 drives the connector 52 to rotate to the extreme left position, the connector 52 can just be aligned with the first chamber 41 or the second chamber 42. Similarly, when the connection cap 5 drives the connector 52 to rotate to the extreme right position, the connector 52 can be aligned with the other chamber. This design makes the alignment of the connector 52 more convenient.

[0052] Further, a vent hole 53 is vertically formed between the upper surface of the connecting cap 5 and the top end surface of the inner wall of the groove. The vent hole 53 is separated from the connecting head 52, and the rotation amplitude of the vent hole 53 is adaptively set with the first chamber 41. In this way, when the airbag layer 22 is restored to the initial state, the vent hole 53 can be driven by the connecting cap 5 to align with the second chamber 42. After alignment, the air in the airbag layer 22 and the first chamber 41 can be discharged through the vent hole 53, and after discharge, the airbag layer 22 is restored to the initial state.

[0053] Based on the above embodiments, as Figure 3 and Figure 4 shown, a set of sealing mechanisms 7 are provided at the inner lower end of the second chamber 42 and the inner wall of the exhaust pipe 6. The sealing mechanism 7 is composed of a mounting rod 71, a baffle 72 and a fixing block 73. Among them, the mounting rod 71 is respectively arranged in the middle of the second chamber 42 and the exhaust pipe 6 along the length direction or the vertical direction through a bracket. Then, the baffle 72 is slidably connected to the outer surface of the mounting rod 71 along the central end, and the diameter of the baffle 72 is adapted to the inner diameters of the second chamber 42 and the exhaust pipe 6, while the fixing blocks 73 are arranged at both ends of the mounting rod 71.

[0054] During use, the gas blown out by the balloon 51 can drive the baffle 72 to move outward. For example, when the balloon 51 is squeezed, the gas in the balloon 51 can simultaneously apply an outward thrust to the baffle 72 in the exhaust pipe 6 and the second chamber 42, so that the baffle 72 in the exhaust pipe 6 and the second chamber 42 can both move. When the baffle 72 in the exhaust pipe 6 moves outward, it will not block the air inlet port of the first air passage 61 (i.e., one side at the inner end of the first air passage 61), so that the gas is allowed to be squeezed into the first air passage 61 and discharged from the tail end of the exhaust pipe 6; when the baffle 72 in the second chamber 42 moves outward, under the action of the stopper, the baffle 72 in the second chamber 42 can be clamped, and after clamping, the baffle 72 can block the air suction port of the second air passage 62 (i.e., one side at the outer end of the second air passage 62), so that the compressed gas in the balloon 51 can be prevented from entering the sheath.

[0055] Similarly, when the balloon 51 returns from the squeezed state, the negative pressure formed in the balloon 51 will drive the baffle 72 in the exhaust pipe 6 and the second chamber 42 to move inward. That is, when the balloon 51 generates negative pressure, the baffle 72 in the exhaust pipe 6 can block the air inlet port of the first air passage 61 (i.e., one side at the inner end of the first air passage 61) after resetting and sliding, so as to avoid the inhalation of external air; while the baffle 72 in the second chamber 42 can open the air suction port of the second air passage 62 (i.e., one side at the outer end of the second air passage 62) after resetting and sliding, so that the heat in the spaced space in the sheath can be inhaled into the balloon 51 and the second chamber 42 through the negative pressure, thus achieving the purpose of active heat dissipation.

[0056] Further, the closing mechanism 7 includes a first closing mechanism and a second closing mechanism. The first closing mechanism is arranged horizontally at the exhaust port of the first air duct 61 (i.e., one side at the inner end of the first air duct 61), while the second closing mechanism is arranged vertically at the suction port of the second air duct 62 (i.e., one side at the outer end of the second air duct 62). When the balloon 51 is squeezed, the first closing mechanism can connect the flow channel between the first air duct 61 and the second chamber 42, while the second closing mechanism can cut off the flow channel between the second air duct 62 and the second branch pipe 45; when the balloon 51 returns from the squeezed state, the first closing mechanism can cut off the flow channel between the first air duct 61 and the second chamber 42, while the second closing mechanism can connect the flow channel between the second air duct 62 and the second branch pipe 45.

[0057] The following is the specific working process of the present invention:

[0058] In use, first put on the entire sheath around the ankle through the first wearing port 11 and the second wearing port 12, and fix it with the binding band 14 after wearing.

[0059] When active heat dissipation is required, the user can rotate the connection cap 5 to align the connection head 52 of the balloon 51 with the second chamber 42. After alignment, reciprocally squeeze the balloon 51. When squeezing the balloon 51 for the first time, the gas in the balloon 51 can be squeezed into the second chamber 42 and the exhaust pipe 6. Since corresponding closing mechanisms 7 are provided between the exhaust pipe 6, the second chamber 42 and the second branch pipe 45, the gas extruded from the balloon 51 can only be discharged through the exhaust pipe 6; when the balloon 51 returns after being squeezed, a negative pressure will be generated, and the suction hole 31 on the inner side of the sheath can generate suction force through the negative pressure. In this way, the heat generated by the user during wearing can be absorbed by the suction hole 31 and the suction layer 3, so that the hot air can be inhaled into the airbag. Then, when the airbag is pressed next time, the inhaled hot air can be squeezed into the exhaust pipe 6 and discharged.

[0060] When passive heat dissipation is required, the user can perform preliminary heat dissipation according to the ventilation holes 32 on the sheath main body 1. If the user wants to improve the use effect of the ventilation holes 32, the user can rotate the connection cap 5 to align the connection head 52 of the balloon 51 with the first chamber 41. After alignment, the user squeezes the balloon 51, and the gas in the balloon 51 can be injected into the first chamber 41. Subsequently, the gas enters the airbag layer 22 through the first branch pipe 44 and expands. When the airbag layer 22 expands, the sheath fixed around the ankle can be expanded, and the ventilation holes 32 can be stretched during the expansion, which helps to increase the aperture of the ventilation holes 32, so as to achieve the effect of improving passive heat dissipation.

[0061] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the technical field of the present application can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered by the protection scope of the present application.
