Description

Knee joint mobility training aid

Technical Field

The application relates to a medical instrument, in particular to a knee joint mobility trainer.

Background

After the knee joint replacement, the training of the knee joint mobility needs to be performed. Through bed-ridden training, the mobility of knee joint is bigger and bigger. If the patient can not see the progress of himself in the process of bed-ridden training, the patient is not good for insisting on training. In addition, for elderly patients, the physical strength is usually insufficient, and during bed-ridden training, there is difficulty in bending the knee, which is often done by sliding the heel over a bed. The friction of the bed against the heel also prevents the bending training from being performed smoothly.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present application aims to provide a knee joint mobility training device which can reduce the friction between the heel and the bed of a patient and can easily make the patient know the progress of the patient.

The application provides knee joint activity degree training ware, it includes: a slide rail, a slide member;

the slide rail is formed into a linear shape, and a sliding groove is formed in the upper side of the slide rail along the extending direction of the slide rail; a plurality of jacks are penetratingly arranged on the slide rail along the extension direction of the slide rail, and a preset distance is formed between every two adjacent jacks; a bolt rod is inserted into one of the plurality of insertion holes and traverses the sliding groove;

the sliding component comprises an L-shaped foot fixing frame and a sliding bracket; the foot fixing frame comprises a first plate and a second plate; the first plate corresponding to the position of the Achilles tendon of the user and the second plate corresponding to the sole of the foot of the user; the first plate and the second plate are vertically connected together; a pair of support plates spaced apart from each other by a predetermined distance are formed outside the connection position of the first plate and the second plate; the lower end of the sliding support comprises four wheels, and the upper end of the sliding support is provided with a support rod; both ends of the support rod are rotatably installed in the pair of support plates; the extending direction of the supporting rod is vertical to the extending direction of the sliding rail; the four wheels move in the sliding groove.

Preferably, a rear side of the first plate is formed with a first ring; a first adhesive tape is inserted in the first ring and is used for being fixed at the ankle joint of a user; a second ring is formed on the lower side of the second plate; a second adhesive tape is inserted into the second ring and is used for being fixed at the arch of the foot of a user.

Preferably, a string is installed on the support rod of the sliding bracket to allow a user to promote the degree of flexion of the knee joint by pulling the sliding bracket.

Preferably, the cross section of the chute is shaped like a Chinese character 'vert'; the upper parts of the four wheels are covered by the upper surface of the sliding rail and cannot be separated from the upper part of the sliding groove.

By arranging the sliding rails and the wheels, the resistance of the bed surface is very small when a user exercises the knee joint mobility (namely the bending degree); through set up the peg on the slide rail, the user can confirm whether own knee joint mobility makes progress through specific peg that can reach by oneself.

Detailed Description

Next, the knee joint mobility training device according to the present invention will be described in detail with reference to the drawings.

The application provides knee joint activity degree training ware, it includes: slide rail 10, sliding member.

The slide rail 10 is formed in a linear shape, and a slide groove 10a is formed on the upper side of the slide rail 10 along the extending direction of the slide rail 10; along the extending direction of the slide rail 10, a plurality of insertion holes 11 are penetratingly arranged on the slide rail, and a predetermined distance, for example, 1cm, is formed between adjacent insertion holes 11; a pin 12 is inserted into one of the plurality of insertion holes 11, and the pin 12 penetrates the slide groove 10 a. The plurality of receptacles 11 may be numbered sequentially. The distal end of the slide 10 may form a plug.

The sliding member includes an L-shaped foot mount 20 and a sliding bracket 30. The foot mount 20 includes a first plate and a second plate; the first plate corresponding to the position of the Achilles tendon of the user and the second plate corresponding to the sole of the foot of the user; the first plate and the second plate are vertically connected together; a pair of

support plates

23a, 23b spaced apart from each other by a predetermined distance are formed outside the connection position of the first and second plates.

The lower end of the sliding bracket 20 comprises four wheels 31, and the upper end is provided with a support rod 32; both ends of the support rod 32 are rotatably mounted in the pair of

support plates

23a, 23 b; the extending direction of the support bar 32 is perpendicular to the extending direction of the slide rail 10; four wheels 31 move in the slide groove 10 a.

The rear side of the first plate is formed with a first ring 21; a first adhesive tape 21a is inserted into the first ring 21 for fixing to the ankle of the user; a second ring 22 is formed on the lower side of the second plate; a second adhesive tape 22a is inserted into the second ring 22 for fixing to the arch of the user's foot.

A string (not shown) is installed on the support rod 32 of the sliding bracket 30 to allow a user to promote the degree of flexion of the knee joint by pulling the sliding bracket 30. One end of the string may be tied to the support bar 32 and the other end of the string is pulled by the user's hand, thereby achieving an external force that promotes the completion of the knee joint.

The cross section of the chute 10a is shaped like a T; the upper portions of the four wheels 31 are covered by the upper surface of the slide rail 10 and cannot be removed from above the slide groove 10, as shown in fig. 2.

When the medical foot fixing frame is used, the sliding rail is arranged at the lower side of the leg of a patient, the foot of the patient is fixed on the foot fixing frame through the first adhesive tape and the second adhesive tape, and when the leg of the patient is in a stretched state, the sliding support is positioned at the position limited by the plug at the far end of the sliding rail, so that the initial sliding position is determined and fixed; the patient can do knee joint bending movement under the action of the leg muscle of the patient or the traction of the rope fixed on the sliding bracket; inserting the plug into the farthest insertion hole which can be reached by the sliding support; in this way, the patient can feel the improvement of the knee joint mobility through the change of the position of the plug.
