Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, 2, 3 and 4, a brace for preventing hyperextension of knee joint of hemiplegia patient comprises: a thigh set 1, which is covered on the front part of the thigh of the user and is fixed with the thigh by a double-layer fixing belt 3 surrounding the thigh; the crus suit 2 covers the front part of the crus of the user and is fixed with the crus through a crus fixing band; the bottom of the thigh suite 1 is hinged with the top of the shank suite 2 through a hinge part 5; the front limiting device 6 comprises a lower pressing block 7 fixedly arranged at the front end of the bottom of the thigh suite 1 and a supporting block 8 fixedly arranged at the front section of the bottom of the shank suite 2, and the lower pressing block 7 is pressed on the top of the supporting block 8 when the knee joint is in a neutral position; the rear limiting stopper 9 is arranged on the upper portion of the thigh sleeve member 1, the rear limiting stopper 9 comprises an upper draw hook 10 fixedly arranged on two inner walls of the rear side of the bottom of the thigh sleeve member and a lower draw hook 11 fixedly arranged on two outer walls of the rear side of the top of the shank sleeve member 2, and the upper draw hook 10 and the lower draw hook 11 are in a mutually matched state when in a neutral position of a knee joint.
In the above arrangement, the thigh set 1 and the shank set 2 are respectively fixed on the affected limb, the hinge portion 5 facilitates the normal knee bending movement of the user, and the front stopper 6 and the rear stopper 9 restrict the bending angle of the thigh and the shank of the user and prevent the hyperextension of the joint when the knee joint is in the neutral position.
Example two:
a first tab opening and a second tab 13 are respectively arranged at two sides of the thigh sleeve 1, and the double-layer fixing strap 3 is connected between the first tab 12 and the second tab 13; the double-layer fixing strap 3 is composed of an elastic strap 14 and a tensile strap 15 which are overlapped, one end of any elastic strap is connected with the first Chinese character 'ri' buckle 12, and the other end of the elastic strap penetrates through the second Chinese character 'ri' buckle 13 and then is connected with the double-layer fixing strap through a magic tape; any one end of the anti-pulling strip 15 is connected with the second buckle 13, and the other end of the anti-pulling strip penetrates through the first buckle 12 and then is connected with the anti-pulling strip through a magic tape.
Through the setting, avoid the user in the motion process to lead to the muscular movement discomfort because of the fixed band problem, because the user is in the walking motion process, along with the relaxation motion of each part muscle, the thigh diameter is also constantly changeing, therefore the unable elasticity requirement that satisfies of single fixed band, and if adopt elastic elasticity structure completely, use when the knee joint hyperextension, thigh external member 1 can't satisfy fixed demand again. The double-layer fixing belt 3 is simply fixed in position through the elastic belt, and is finally fixed when thigh muscles contract through the anti-pulling belt 15, so that the thigh sleeve 1 can be normally fixed on the thigh no matter when the muscles relax or contract, and the constraint requirement when the joints are over-stretched is met.
Example three:
the shank fixing band comprises upper fixing bands 17 connected to two sides of the top of the shank kit 2, lower fixing bands 18 connected to two sides of the bottom of the shank kit 2 and a heel fixing sleeve 19 connected to the bottom end of the shank kit 2, and the upper fixing bands 17 and the lower fixing bands 18 are connected through magic adhesive fasteners.
Through the arrangement, the shank external member 2 is mainly fixed with the muscle key area of the shank through the upper fixing band 17 and the lower fixing band 18, so that the stretching area of the shank muscle is avoided, meanwhile, the heel fixing sleeve 19 is fixed with the heel in the using process, and the problems of upward movement, dislocation and rotation of the shank external member 2 in the movement process are avoided.
Example four:
the articulated part 5 comprises lower shaft sleeves 20 arranged at two sides of the top of the shank suite 2 and upper shaft sleeves arranged at two sides of the bottom of the thigh suite 1, a lower shaft head 22 is matched in the lower shaft sleeves 20, an upper shaft head 23 is matched in the upper shaft sleeves, the upper shaft head 23 is coaxially matched with the lower shaft head 22, and a coupling sheet 24 for transmitting torque is arranged between the upper shaft head 23 and the lower shaft head 22; one end of the coupling piece 24 corresponding to the lower shaft head 22 is provided with an inner slide rail 25, and the lower shaft head 22 is in sliding fit with the inner slide rail 25 through an inner shaft groove 27; one end of the coupling piece 24 corresponding to the upper shaft head 23 is provided with an outer slide rail 26, and the upper shaft head 23 is in sliding fit with the inner slide rail 25 through an outer shaft groove 28.
In the above arrangement, in order to ensure flexible movement of the knee joint of the user, in the flexion and extension process of the knee joint, the inner slide rail 25 and the outer slide rail 26 slide in the inner shaft groove 27 and the outer shaft groove 28 respectively along with the rotation of the upper shaft head 23 and the lower shaft head 22, so that the axial radial variation between the upper shaft head 23 and the lower shaft head 22 is adapted, the multi-angle movement of the knee joint of the user is met, the interference of the brace on the movement of the user is avoided, and the wearing comfort is improved.
Example five:
the front protective plate 29 covers the working range of the front stopper 6 and is connected with the surfaces of the thigh kit 1 and the shank kit 2 through elastic connecting belts at the upper end and the lower end respectively.
Through the arrangement, the front-end limiting stopper 6 wrapped by the front protection sheet 29 avoids the external interference, such as the foreign matter entering the working area between the lower pressing block 7 and the supporting block 8 and influencing the neutral position angle of the leg.
Example six:
the side hook protection plate 30 covers the working range of the rear stopper 9 and is respectively connected with the surfaces of the thigh kit 1 and the shank kit 2 through elastic connecting belts at the upper end and the lower end.
In the above arrangement, the side hook protection sheet 30 prevents the external object from interfering with the matching relationship between the upper drag hook 10 and the lower drag hook 11, and prevents the rear stopper 9 from losing effectiveness due to the supporting hook.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
