CZ307566B6 - A mechanical autoextensor - Google Patents

Abstract

A mechanical autoextensor consists of a metal frame (2) attached to a plate (1), where metal pipes (4) are attached to the metal frame (2) via joints (3), wherein two sliding stirrups (5) are attached to the metal pipes (4) and, between the stirrups (5), a handle (7) is attached to the pipes (4) via joints (6) and leather straps (8) are threaded on the stirrups (5).

Description

Mechanical autoextensor

Field of technology

The mechanical autoextensor ensures the extension of the angle between the bones of the lower limb at the location of the knee joint, ie extension.

It is a rehabilitation aid, enabling people to perform extension completely independently, ie. regardless of the help of a rehabilitation worker or other person.

The effects of regular extension prevent the shortening of tendons, attachments and muscles, and relieve pain that may subside over time.

Prior art

The prior art is known only as a device or aid for performing bending of the lower limb in the knee, the so-called flexion, i.e. the opposite of what the mechanical autoextensor is designed for.

The essence of the invention

The mechanical autoextensor consists, as shown in Figure 1, of a fixed and a movable part. The metal frame 2, fixed to the plate, is the fixed part on which the user places the limb. Above the limb is a movable part of a mechanical autoextensor, consisting of two metal tubes 4, two pressure sliding clamps 5, two leather straps 8 and a metal handle 7. Both parts are connected by two joints 3, the extent of which is for comfortable placement of the limb on the plate 180 °. The metal handle 7 is also connected to the two rods 6 by rods 4. However, the joints 6 are only movable in the range of up to about 95 °, so that the handle 7 can exert pressure on the moving part of the mechanical autoextensor due to the desired effect.

Explanation of the drawing

Giant. 1 shows a mechanical autoextensor in terms of its construction, function and efficient use, i. also as a manual in particular for the lower limb to be correctly inserted with the heel towards the open structure onto the plate 1 so that the stirrups 5 are above and below the knee of the upper part of the limb and so that the handle 7 can exert pressure on the limb downwards towards the plate 1.

Examples of embodiments of the invention

The mechanical autoextensor consists, as shown in Figure 1, of a fixed and a movable part. The metal frame 2, fixed to the plate, is the fixed part on which the user places the limb. Above the limb is a movable part of a mechanical autoextensor, consisting of two metal tubes 4, two pressure sliding clamps 5, two leather straps 8 and a metal handle 7. Both parts are connected by two joints 3, the extent of which is for comfortable placement of the limb on the plate 180 °. The metal handle 7 is also connected to the two rods 6 by rods 4. However, the joints 6 are only movable in the range of up to about 95 °, so that the handle 7 can exert pressure on the moving part of the mechanical autoextensor due to the desired effect.

The stabilizing fixed plate 1 can be wooden or plastic of thickness approx. 5 mm. A rod or tube can be used for the fixed frame 2, the movable rods 4 and the movable handle 7, all metal, but can

- 1 CZ 307566 B6 round hardened plastic can also be used. The metal sliding brackets 5 can also be made of hardened plastic. These stirrups can be made variably, ie. made so that they can be used for different limb thicknesses, they can also be provided with clamping screws so that they can be fixed to the rods 4, respectively. At the joints 3 and 6, a metallic material should be preserved. For the joint 6, it is necessary, for the correct functionality of the aid, to use in the assembly a joint structurally made with an openability up to approx. Leather straps 8 can be replaced by fabric or plastic. For easier handling of the mechanical autoextensor on the floor, small furniture castors can also be mounted under the fixed plate 1.

Industrial applicability

With a mechanical autoextensor, the user can perform the extension of the lower limb all by himself and thus becomes completely independent of the help of a rehabilitation worker or other person, because with the limb lying horizontally on the surface effective extension exercises, without the help of another person. when it is a handicapped lower limb.

A mechanical autoextensor can also be beneficial to humans, generally with more or less knee problems.
