Quadriceps femoris rehabilitation training bed

Abstract

The invention discloses a quadriceps femoris rehabilitation training bed, and relates to the field of medical devices. The quadriceps femoris rehabilitation training bed includes a bed body, two flexion and extension mechanisms, two foot posture adjustment mechanisms, two guideways, two driving mechanisms and a controller. Each flexion and extension mechanism comprises a thigh support component and a crus support component, wherein one end of the thigh support component is articulated with a fixed support base connected with the bed body, the other end of the thigh support component is articulated with the end of the crus support component, the lower portion of the other end of the crus support component is articulated with a slider, and each slider can slide on the corresponding guide rail. The ends, away from the thigh support components, of the crus support components are provided with the foot posture adjustment mechanisms, and the ends, away from the crus support components, of the thigh support components are connected with the driving mechanisms which can drive the thigh support components to do reciprocating motion up and down, and the driving mechanisms are controlled by the controller. Through the combination of the quadriceps femoris rehabilitation training bed and active and passive rehabilitation strategies, quadriceps strength regeneration is effectively stimulated, the required driving force is reduced, and the flexibility of use is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a quadriceps muscle rehabilitation training bed. Background technique [0002] The role of the quadriceps is crucial to the lower body, and many movements of the lower body are completed by the strength of the quadriceps. Many patients with knee surgery or lower extremity fractures need to stay in bed for a long time, and prolonged immobilization during treatment can lead to quadriceps atrophy. At present, the methods for quadriceps muscle strength training include artificial, equipment, elastic bands and so on. However, due to inaccurate joint angles, uneven force and single training mode of equipment during manual training, it is easy to miss the best time for treatment. There are few existing lower limb rehabilitation robots for lower limb training for patients with quadriceps injuries: there is a commercial CPM that has been put into production, which can complete flexion a...

However, due to inaccurate joint angles, uneven force and single training mode of equipment during manual training, it is easy to miss the best time for treatment

There are few existing lower limb rehabilitation robots for lower limb training for patients with quadriceps injuries: there is a commercial CPM that has been put into production, which can complete flexion and extension exercises, but it has a large driving torque and only one passive training mode. The cycle is relatively long, so it is necessary to design a machine for quadriceps training so that patients can receive more effective treatment
