The knee joint exerciser

This utility model relates to physical therapy device or tempers the extension or the crooked utensil of usefulness, is meant the unpowered telescopic spring shelf structure of a kind of employing especially, utilizes spring tension and upper limb to cooperate pulling force to combine autonomous knee sprung strength, and joint of the lower extremity is gone down on one's knees; And utilize limbs weight and from the knee stretching strength amount, make joint of the lower extremity stretch knee joint.Thereby the rehabilitation personnel is organically combined with active passive, can prevent the knee joint exerciser of amyotrophy and limds edema, enhancing rehabilitation personnel muscular strength and body constitution.

Existing motor-operated limb joint rehabilitation device that uses adopts motor drives expansion link dynamic structure, but owing to the passive lower limb of accepting of rehabilitation personnel bend and stretch, thereby have following defective.First because by the passive by force joint of going down on one's knees of stretching of machinery, when the setting range of activity was excessive, patient was difficult to bear affliction and causes tension injury sometimes; And when the setting range of activity is too small, the less rehabilitative action that can play; It is just right to be difficult to range of activity is set to.Second lower limb are not taken the initiative and are bent and stretched and by the full passive activity of machinery, and the amyotrophy of limbs, edema etc. are not had rehabilitative action.The 3rd use motor-operated limb joint rehabilitation device price high-leveled and difficult with promote at basic hospital and family in use, and this product structure is complicated in case damage and be difficult to keep in repair.Thereby limited further promoting the use of of this product.

The purpose of this utility model just is to overcome the defective of existing limb joint rehabilitation device, provides a kind of employing unpowered telescopic spring shelf structure, utilizes spring tension and upper limb to cooperate pulling force to combine autonomous knee sprung strength, and joint of the lower extremity is gone down on one's knees; And utilize limbs weight and from the knee stretching strength amount, make joint of the lower extremity stretch knee joint.Thereby the rehabilitation personnel is organically combined with active passive, can prevent the knee joint exerciser of amyotrophy and limds edema, enhancing rehabilitation personnel muscular strength and body constitution.

Knee joint exerciser of the present utility model is made of with circle, the little leg support of expansion bracket, the big leg support of expansion bracket, spring, support, hinge, chute, base, stable axis bearing, boundary belt; Two chutes are welded on two bases that are positioned at two ends; big leg support one end of expansion bracket is connected in an end of chute by stable axis; its other end links to each other with an end of the little leg support of expansion bracket by two hinges; two bearings that slide only are equipped with in expansion bracket shank carriage other end end in chute; the big leg support outer rim of expansion bracket is welded with a pair of boundary belt with enclosing; expansion bracket shank carriage outer rim is welded with two pairs of boundary belts with enclosing; support Cheng Menzhuan two ends are inserted in the screw cap hole of chute outer rim; the little leg support of expansion bracket passes through the end that hook connects spring by the crossbeam at bearing one end place, and the other end of spring is fixed on the base hook on opposite.Spring can be regulated as required, generally between the 1-5 root.When knee joint exerciser of the present utility model was in running order, base and chute maintained static, and bearing comes rollback moving on chute, and the big leg support of little leg support of expansion bracket and expansion bracket constitutes expansion bracket and does the folding activity by hinge.The big leg support of expansion bracket is a stop with the stable axis, moves up and down, and the spring that rolls forward of the bearing when the hinge place descends on the little leg support of expansion bracket is strained gradually, and the bearing spring that rolls backward loosens gradually when rise in the hinge place.When lower limb stretch, the strength of utilizing the deadweight of lower limb and stretching knee joint, stretch hip, make expansion bracket along with the action of lower limb is and then stretched, the big leg support proximal ends of expansion bracket is rotated down around stable axis, bearing rolls forward, the hinge place drops on the support gradually, the spring tension, and little leg support of expansion bracket and the big leg support of expansion bracket finally form the angle of 175-180 degree; When the lower limb flexing, utilize the pulling force and the strength of going down on one's knees, bending hip of spring, sometimes also add the upper limb pulling force, the big leg support proximal ends of expansion bracket rotates up around stable axis, bearing rolls backward, rise gradually in the hinge place, relaxing of spring, the final angle that forms about 60 degree of little leg support of expansion bracket and the big leg support of expansion bracket.So perseveration by passive with the initiatively flexible combination of rehabilitation personnel, reaches prevention amyotrophy and limds edema, the purpose of muscle strength reinforcing and body constitution.

Advantage of the present utility model just is to make simple, the easy to carry and maintenance easily that is difficult for breaking down of product structure owing to adopt unpowered telescopic spring shelf structure; By passive with the initiatively flexible combination of rehabilitation personnel, list can make knee sprung, and can prevent amyotrophy, limds edema, muscle strength reinforcing and whole body body constitution, helps the very fast rehabilitation of limb function; Because kneed range of activity and speed can be regulated control voluntarily, make each activity be issued to maximum in self endurable misery; When giving up doing exercise, will suffer from limb and place on the expansion bracket, the passive flexing effect of continuing is arranged; After knee joint exerciser of the present utility model is applicable to quadricepsplasty, after knee arthroplasty postoperative and nearly kneed fracture and the operation on soft tissue and the postoperative early function of varicose veins of the lower extremity recover to take exercise, since cheap, be particularly suitable in basic hospital and family, using.
