Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an adjustable footrest for children to prevent foot drop. Background Art

[0002] Foot drop refers to insufficient ankle dorsiflexion during the swing phase, which often coexists with inversion or eversion of the foot, and can lead to clearance disorders. Compensatory mechanisms include: increased ipsilateral hip and knee flexion during the swing phase, circular movement of the lower limbs, and trunk tilt to the opposite side. Common causes are inactivity of the tibialis anterior muscle or abnormal activity phase. Simple foot drop is mainly seen in spinal cord injury, paralysis, and peripheral nerve injury.

[0003] The typical symptoms of foot drop are that the dorsiflexion of the foot cannot reach the functional position and the ankle joint is restricted. Patients may walk in a circular gait, which may be accompanied by pain and fatigue. Trauma causes peripheral nerve damage, or diseases such as spinal cord injury and polio cause the tibialis anterior muscle to be inactive or abnormal, resulting in foot drop. For the treatment of foot drop, patients can be encouraged to wear orthopedic braces and given drugs such as nerve nutrition. At the same time, they should actively carry out rehabilitation exercises and, if necessary, surgical treatment can be performed, which can improve gait, relieve pain, and avoid atrophy of the tibialis anterior muscle.

[0004] In major hospitals, in order to prevent foot drop in children, most children are encouraged to wear orthopedic foot braces. The common anti-foot drop foot braces are generally L-shaped, including a foot support and a leg support. After being fixed to the child's foot, the child's foot and leg can be made at 90 degrees to correct the foot drop.

[0005] Although the L-shaped anti-foot drop foot support described above is widely used, it still has certain defects and shortcomings;

[0006] Specifically, on the one hand, the length of the foot support is fixed. When it is needed for children with different foot lengths, the corresponding foot support needs to be customized to make the length of the customized foot support match the length of the child's foot. This makes the corresponding L-shaped anti-foot drop foot support not very universal and not very practical. On the other hand, after being fixed to the child's foot, it can only support the child's foot and legs. There are no clamping components on the left and right sides and the front and back ends of the child's foot, so the fixation of the child's foot is not very good, which in turn makes the foot drop correction effect of the child not very good. In addition, when the child wears it and walks, the periphery of the foot is exposed, which is easy to splash water and get dirty, making it uncomfortable to use.

[0007] Therefore, the existing problems need to be solved. Summary of the invention

[0073] The footrest body 10 includes a sole support plate 101, a sole guard 102, a toe guard 103, a toe cover plate 104, a leg support plate 105 and a leg guard 106; the sole guard 102 is provided with two pieces, and is fixed to the left and right sides of the upper end surface of the sole support plate 101 in the front and rear directions; the toe guard 103 stands in the front side of the upper end surface of the sole support plate 101 in the left and right directions, and its left and right sides are connected to the front sides of the two sole guards 102 to form a whole; the front side of the toe cover plate 104 is connected to the toe guard 103 The upper edges are connected to form a whole, and the left and right sides are connected to the front sides of the upper edges of the two sole guards 102 to form a whole; the leg support plate 105 is vertically fixed to the rear side of the upper end surface of the sole support plate 101 along the left and right directions, and its lower edges on the left and right sides are connected to the rear sides of the two sole guards 102 to form a whole; the leg guard 106 is provided with two pieces, and is fixed to the left and right sides of the front end surface of the leg support plate 105 along the front and rear directions, and its lower edges are connected to the rear sides of the upper edges of the two sole guards 102 to form a whole;

[0074] The first inflatable balloon 20 is adhered to the rear end surface of the toe guard 103, and the first inflatable balloon 20 can swell backward when inflated to flexibly press against the toes of the child patient;

[0075] The second inflatable balloon 30 comprises a left front inflatable portion 301, a right front inflatable portion 302, a left upper inflatable portion 303 connected upwardly to the rear end of the left front inflatable portion 301, a right upper inflatable portion 304 connected upwardly to the rear end of the right front inflatable portion 302, and a The rear inflatable part 305 is between the rear end and the rear end of the upper right inflatable part 304; the left front inflatable part 301 is glued to the middle to the rear of the right end surface of the left foot guard 102; the right front inflatable part 302 is glued to the middle to the rear of the left end surface of the right foot guard 102; the upper left inflatable part 303 is glued to the right end surface of the left leg guard 106; the upper right inflatable part 304 is glued to the left end surface of the right leg guard 106; the rear inflatable part 305 is glued to the front end surface of the leg support plate 105, and when the second inflatable balloon 30 is inflated, the left front inflatable part 301 and the right front inflatable part 302 can bulge towards each other, and press against the two sides of the sole of the child patient with opposite flexibility, and the upper left inflatable part 303 and the upper right inflatable part 304 The two parts can swell towards each other to flexibly press against the two sides of the heel and the two sides of the calf of the child patient. The rear inflatable part 305 can swell forward to flexibly press against the calf and heel of the child patient.

[0076] Based on the above, it is clear that when the present application is implemented, it is mainly used as an improved adjustable child anti-foot drop footrest 1000.

[0077] On the one hand, the footrest body 10 includes a foot guard 102, a toe guard 103, a toe cover 104 and a leg guard 106 that can surround the periphery of the child patient's foot, so that the periphery of the child patient's foot can be surrounded in all directions, so that when the child patient walks wearing the present application, the periphery of the child's foot is surrounded and is not easily splashed with water or stained with mud, making the use of the present invention comfortable.

[0078] On the other hand, the present application is also provided with a first inflatable balloon 20 for adjusting the tightness of the footrest body 10 in the front-to-back direction when a child patient wears the footrest body 10 described in the present application, and a second inflatable balloon 30 for adjusting the tightness of the footrest body 10 in the left-to-right direction when a child patient wears the footrest body 10 described in the present application. In this way, after the child patient wears the present application, the left and right sides and the front and back ends of the child patient's foot are flexibly clamped, so that the child patient's foot is well fixed, and then the child patient's foot drop correction effect is good.

[0079] At the same time, the sizes of the rear inflated parts 305 of the first inflatable balloon 20 and the second inflatable balloon 30 can be adjusted, so that the degree of their bulging towards each other can be adjusted, so as to adapt to a certain degree of bulging to clamp the soles of children with different sole lengths, making the application highly versatile and applicable to children with different sole lengths within a certain range, so that the application is practical to use.

[0080] Furthermore, the present application has outstanding substantive features and significant improvements, resulting in better use effects.

[0081] Further, in the technical solution, the present application also includes a third inflatable balloon 40 for adjusting the tightness of the foot support body 10 in the up-down direction when the child patient wears the foot support body 10;

[0082] The third inflatable balloon 40 is formed into an inverted U-shaped structure and is adhered to the lower bottom surface of the toe cover plate 104. When the third inflatable balloon 40 is inflated, its upper portion can bulge downward and both sides of its lower portion can bulge toward each other.

[0083] Thus, it can be understood that when the upper part of the third inflatable balloon 40 bulges downward, it can flexibly press against the upper surface of the child patient's toes and the upper surface of the front end of the instep. When the lower parts of the third inflatable balloon 40 bulge toward each other, they can flexibly press against the big toe, little toe and both sides of the front end of the instep of the child patient, so that the child patient's foot can be flexibly fixed in all directions and the child patient can wear it comfortably.

[0084] Furthermore, in a specific implementation, a first inflation head 201 is connected to the top of the first inflation balloon 20 of the present application, and a first sealing cover 202 is sealed on the outside of the first inflation head 201; a second inflation head 306 is connected to the right side of the upper right inflation part 304 of the second inflation balloon 30 of the present application, and a second sealing cover 307 is sealed on the outside of the second inflation head 306; and a third inflation head 401 is connected to the top of the third inflation balloon 40 of the present application, and a third sealing cover 402 is sealed on the outside of the third inflation head 401;

[0085] Based on this, in the present embodiment, a first through hole 1041 is provided on the front side of the upper end surface of the toe cover 104 to allow the first inflation head 201 to extend out; a second through hole 1061 is provided on the right end surface of the right leg guard 106 to allow the second inflation head 306 to extend out; and a third through hole 1042 is provided on the rear side of the upper end surface of the toe cover 104 to allow the third inflation head 401 to extend out.

[0086] Therefore, when it is necessary to inflate the first inflatable balloon 20, open the first sealing cover 202 and connect an inflating device to the first inflating head 201; when it is necessary to inflate the second inflatable balloon 30, open the second sealing cover 307 and connect an inflating device to the second inflating head 306; when it is necessary to inflate the third inflatable balloon 40, open the third sealing cover 402 and connect an inflating device to the third inflating head 401, which makes the present application easy to operate.

[0087] As an optimization solution, the present application also includes a flat inflatable balloon 100 for inflating the first inflatable balloon 20, the second inflatable balloon 30 and the first inflatable balloon 20 during specific implementation;

[0088] Among them, the leg support plate 105 is thickened, and a flat square-shaped cavity 1051 is opened downward on its upper end surface. The flat inflated balloon 100 can be carried and stored in the flat square-shaped cavity 1051, and the top of the flat inflated balloon 100 is connected to a one-way exhaust valve 1001 adapted to be plugged into the first inflation head 201, the second inflation head 306 and the third inflation head 401, and is provided with a one-way air intake valve 1002 to allow external air to enter.

[0089] Therefore, the present application is provided with an inflation device, namely, the flat inflatable balloon 100, so that when a child patient wears the present application, the flat inflatable balloon 100 can be used anytime and anywhere to inflate the first inflatable balloon 20, the second inflatable balloon 30 and the first inflatable balloon 20, making it convenient to use and eliminating the need to find another inflation device. The flat inflatable balloon 100 is a flat structure and is stored in the flat square body cavity 1051 when not in use, so that it does not occupy much space, so that the flat square body cavity 1051 can be opened thinner, such as its internal left and right width can be set to 5.0 cm, and the internal front and back gap can be set to 1.0 cm, so that the leg support plate 105 will not be too thick and increase the weight, that is, the present application can still maintain a relatively light weight so that the child patient will not feel bulky when wearing it.

[0090] In a preferred embodiment, the upper and lower lengths of the leg support plate 105 are at least ten centimeters, and preferably fifteen centimeters, so that the flat square-shaped cavity 1051 has a sufficient depth and the flat inflated balloon 100 accommodated therein is long enough to have sufficient air volume, so that the first inflatable balloon 20, the second inflatable balloon 30 and the third inflatable balloon 40 can be quickly inflated later.

[0091] Furthermore, in a specific implementation, the present application further includes an openable and closable surface cover 50 for covering the upper notch of the flat square-shaped cavity 1051;

[0092] The upper notch of the flat square volume 1051 is sunken downward to form a step 1052; the middle of the left inner wall of the step 1052 is provided with a rotation groove 1053 to the left, and the middle of the right inner wall is sunken to the right to form a pit 1054;

[0093] The left end surface of the openable and closable cover 50 is provided with a rotating ear 501 protruding to the left, and the middle part of the right end surface is provided with a screw groove 502 to the left, and a ball screw 503 is fixed to the right in the screw groove 502, and a handle 504 is protruding upward on the right part of the upper end surface; the openable and closable cover 50 is placed on the concave step 1052; the rotating ear 501 is limitedly clamped in the rotating groove 1053; the ball on the right end of the ball screw 503 is elastically clamped in the pit 1054;

[0094] Therefore, when the handle 504 is pinched with force, the rotating ear 501 on the left end face of the openable and closable cover 50 can rotate around the rotating groove 1053, and the ball at the right end of the ball screw 503 on the right end face will slide away from the pit 1054, and the openable and closable cover 50 will open the upper notch of the flat square-shaped cavity 1051, so as to facilitate taking out the flat inflated balloon 100 from the flat square-shaped cavity 1051 or placing the flat inflated balloon 100 into the flat square-shaped cavity 1051.

[0095] In the above operation, the ball at the right end of the ball screw 503 is elastically clamped in the pit 1054, so that the openable and closable cover 50 is well fixed when closed and also easy to open. Only by slightly lifting the handle 504, the ball at the right end of the ball screw 503 can be driven to slide out of the pit 1054.

[0096] It should be added that, in specific implementation, the present application also includes two horizontally placed L-shaped support plates 60;

[0097] The lower part of the leg support plate 105 is provided with a pull-out groove 1055 penetrating the left and right end surfaces thereof; the left and right end surfaces of the leg support plate 105 are respectively provided with a screw hole 1056 inwardly formed at the front side of the pull-out groove 1055;

[0098] The two transverse L-shaped support plates 60 each include a first support plate 601 arranged forward and a second support plate 602 arranged opposite to each other and connected to the rear end of the corresponding first support plate 601; the two first support plates 601 are respectively provided with butterfly bolts 6011 corresponding to the screw holes 1056 at the corresponding positions; the two second support plates 602 extend into the pull-out groove 1055 from the left notch and the right notch thereof; the two butterfly bolts 6011 are correspondingly screwed into the two screw holes 1056 to lock and fix the two second support plates 602 into the pull-out groove 1055 accordingly. At this time, the two first support plates 601 are correspondingly fitted to the left and right end surfaces of the leg support plate 105 so as not to occupy the external space;

[0099] Therefore, when the two butterfly bolts 6011 are loosened, the lengths of the two second support plates 602 extending out of the left and right notches of the pull-out slot 1055 can be adjusted.

[0100] Therefore, when the two second support plates 602 are extended accordingly, the child patient can walk steadily and the foot wearing the present invention is not easily tilted to the side. Similarly, when the child patient lies flat on the bed, the two second support plates 602 are also extended accordingly, which can help the child patient to point the toes of the foot wearing the present invention upwards and the foot is not easily tilted to the side.

[0101] It should be further added that, in a specific implementation, the present application also includes a first tightening belt 70 for tightening the instep of the child patient and a second tightening belt 80 for tightening the calf of the child patient;

[0102] The first tightening belt 70 is connected upward to the left end surface of the left sole guard 102; the second tightening belt 80 is connected forward to the left end surface of the left leg guard 106;

[0103] On this basis, the right end surface of the right foot guard 102 is provided with a first tightening ring 1021 opposite to the first tightening belt 70 for the first tightening belt 70 to pass through; the right end surface of the right leg guard 106 is provided with a second tightening ring 1062 opposite to the second tightening belt 80 for the second tightening belt 80 to pass through.

[0104] Preferably, in this embodiment, the first tightening strap 70 includes a first elastic band 701 connected to the left end surface of the left foot guard 102 and a first Velcro band 702 connected to the upper end of the first elastic band 701; the second tightening strap 80 includes a second elastic band 801 connected to the left end surface of the left leg guard 106 and a second Velcro band 802 connected to the front end of the second elastic band 801.

[0105] Therefore, when the first Velcro strap 702 passes through the first tightening ring 1021 and is adhered to itself, the first tightening strap 70 can be used to tighten the instep of the child patient, and when the second Velcro strap 802 passes through the second tightening ring 1062 and is adhered to itself, the second tightening strap 80 can be used to tighten the calf of the child patient.

[0106] At the same time, the first tightening belt 70 has an elastically stretchable first elastic band 701, and the second tightening belt 80 has an elastically stretchable second elastic band 801. Therefore, when the first tightening belt 70 tightens the instep of the child patient, it is elastically tightened instead of rigidly tightened, so that it is not easy to hurt the instep of the child patient. When the second tightening belt 80 tightens the calf of the child patient, it is also elastically tightened instead of rigidly tightened, so that it is not easy to hurt the calf of the child patient. Therefore, the first tightening belt 70 and the second tightening belt 80 in this embodiment are comfortable to use.

[0109] Therefore, when a child wears the present invention and walks, the multiple massage convex points 901 can massage the soles of the child's feet to promote blood circulation in the soles of the feet. The gap between two adjacent massage convex points 901 can play a role in perspiration and ventilation. The energy released by the multiple germanium stone particles 902 can activate the cells of the soles of the child's feet, eliminate fatigue, dredge meridians, promote blood circulation, and improve immunity, etc., which is more helpful to the health of the child and has a better effect in preventing foot drop.

[0110] In the preferred embodiment, the plurality of massage protrusions 901 are all made of soft rubber material, and their fixing surfaces are all provided with inward pits, and germanium stone particles 902 are pre-embedded in the corresponding pits, and then the fixing surfaces are glued or hot-melted to the corresponding upper end surface of the therapeutic pad 90.

[0111] In this embodiment, the footrest body 10 is preferably made of hard plastic material so that it is hard and light, so that it is not bulky to wear.

[0112] Other embodiments and the like are not described one by one here.

[0113] To sum up, the overall structure of the present invention is simple, easy to implement, easy to operate, highly practical, highly specific, and has low manufacturing cost. There is no need to increase too much cost in the improvement of the structure and the improvement of the technology, which makes the present invention bound to have good market promotion value.
