Description

Self-training device for knee joint flexion and extension functions

Technical Field

The utility model relates to a medical rehabilitation device, in particular to a rehabilitation training device for the flexion and extension functions of the knee joints of patients.

Background

The knee joint is the most complex joint of the whole body and the joint with the highest incidence rate, and is the joint for ensuring normal walking of people. When legs or knee joints of people are injured and the knee joints cannot be bent and stretched normally after the operation, normal walking is affected. Some brain patients can affect leg nerves after operation, and the knee joint can not normally flex and stretch. Therefore, the patients in the above situations need to strengthen isometric contraction training and knee joint flexion and extension training of the quadriceps femoris, prevent muscle atrophy or adhesion, and recover the mobility of the knee joint.

At present, various rehabilitation devices are used for leg training, and most of the devices are passive, such as a CPM limb intelligent motion training and treatment nursing device (CPM machine for short). The CPM machine usually adopts a power transformer, a stepping speed reducing motor, a control panel, a driver, a limit switch and a shell as main power parts, and uses a linear sliding table or a speed reducer to simulate the motion of a human body such as reciprocating extension and abduction, so that a patient can be forcibly trained. When the device is used, a patient is attached to the CPM machine, the angle of passive flexion is set according to the range and characteristics of the four limbs of the human body, and the device can be used for performing motion range training of straightening, flexion, abduction and the like of the four limbs. Because the passive and forced training is received, the training intensity is not easy to control, the facial expression change of the patient needs to be observed at any time, and the phenomenon that the patient suffers pain and is injured secondarily to influence the rehabilitation process due to the larger labor load on the calf muscle is avoided.

When a patient is separated from a rehabilitation instrument for daily walking training, in order to prevent the knee joint from softening, a companioner needs to support the knee joint, which is very inconvenient.

In view of the above, there is a need for a self-training device for knee joint flexion and extension controlled by the patient himself.

SUMMERY OF THE UTILITY MODEL

In order to satisfy the needs of patient's knee joint function oneself initiative training of stretching that bends, the utility model relates to a knee joint function oneself trainer that bends.

The technical scheme of the utility model is that the self-training device for the knee joint flexion and extension function is two trouser legs which are made of hard-skin leather materials and are arranged on the lower limbs of a patient in a penetrating way, the two trouser legs comprise a thigh trouser leg and a diameter trouser leg, and the thigh trouser leg and the diameter trouser leg are movably connected into a whole; the movable connection structure is that an upper steel sheet shell and a lower steel sheet shell are respectively attached to the knee parts of the thigh trouser legs and the radial trouser legs, two sides of the upper steel sheet shell and the lower steel sheet shell are respectively provided with a hinge lug which corresponds to each other, the hinge lugs are provided with hinge holes, and the thigh trouser legs and the radial trouser legs are hinged together by a pin shaft through the hinge holes; the knee nest positions corresponding to the thigh trouser legs and the radial trouser legs are provided with oblique openings, and the thigh trouser legs can be bent backwards for a certain angle relative to the radial trouser legs through the oblique openings; the front parts of the upper steel sheet shell and the lower steel sheet shell are respectively welded with a hanging rod piece; a tension piece is arranged between the two hanging rod pieces, and the trouser legs of the thigh have certain bending strength relative to the trouser legs of the diameter under the action of the tension piece.

The preferred scheme is that the tension piece is a tension spring, the tension springs are combined together, and the tension is adjusted by increasing or decreasing the number of the springs.

Preferably, the tension member can be formed by winding a closed loop of elastic ribs in multiple ways, and the tension is adjusted by increasing or decreasing the number of winding ways.

Preferably, the rear parts of the thigh trouser legs and the diameter trouser legs are provided with slits, and the slits are provided with binding structures; the binding structure may be in the form of a zipper or an adhesive tape, in addition to the buckle. When in use, the thigh trouser legs and the radial trouser legs are respectively tied tightly at the thigh part and the shin part of the lower limb of a patient and are used for supporting and relieving the bending force of the knee joint.

The utility model has the advantages that the thigh trouser legs and the radial trouser legs are slotted and loosened during use, the patient wears on the lower limb, the thigh trouser legs and the radial trouser legs are respectively positioned at the upper and lower positions of the knee and are tightly wrapped by the binding structure, and the tension piece is adjusted to achieve the maximum tension, so that the bending strength of the knee joint of the patient at the early stage of rehabilitation is sufficiently supported; the patient starts leg training and does walking action or squatting action; because of the mechanical resistance of the tension piece, the knee joint of the patient is blocked, the supporting force is increased, the leg can not be softened and the patient can not fall down, and the self-training can be realized without being held by the user; during training, muscles naturally contract and relax rhythmically, namely, the tightening and loosening force is usually called; along with the training, the pulling force of the pulling force piece is gradually reduced according to the rehabilitation degree, and the normal walking is gradually recovered.
