RU2290242C1 - Simulator for restoring motion activity of foots - Google Patents

Abstract

FIELD: apparatuses for rehabilitation of patients after injury of spinal cord, children suffered with cerebral paralysis and so on.

SUBSTANCE: simulator includes stationary plate jointly coupled with movable plate for placing foots. In center of movable plate handle of hand drive unit is mounted for rocking movable plate. Flywheel is horizontally mounted on stationary plate for accumulating energy. Flywheel is joined with possibility of rotation with hand drive unit and through crank drive mechanism it is joined with movable lever. The last is joined with plate for placing foots.

EFFECT: improved efficiency of using simulator due to possibility of free passive rocking of foots while using force of patient hands for short time period.

Description

The simulator for restoring motor activity of the feet refers to rehabilitation simulators for restoring motor activity of the feet of patients with spinal cord injury, cerebral palsy and other similar diseases.

Similar devices, namely, simulators of various designs for the feet, are used when working out the calf muscles of the legs (see www.stormoff.ru / foreign / bigfitn.htm # 815, www.jdc.org.il/fsu/icww/db/mc /rehabilitation%20equipment/rehcat(lvov).doc).

The closest analogue of the claimed invention is a simulator for restoring motor activity of the feet, containing a fixed plate, a movable plate pivotally connected to it for installing feet, on which a handle for manually swinging it is fixed (SU No. 725666, class A 61 N 1 / 02.1980 )

However, this simulator can only be used by patients who have retained motor activity of the feet, able to overcome the force of gravity. It does not allow patients who have very weak foot movement, are unable to overcome gravity, but have active movement under conditions of unloading (International standards for assessing neurological disorders in spinal and spinal cord injuries. D.E. Yarikov, I.N. .Shevelev, A.V. Baskov, Research Institute of Neurosurgery named after academician NN Burdenko RAMS, Moscow. Journal of Neurosurgery Issues, No. 1, 1999).

To improve the recovery of motor activity of the feet of patients with weak movements in the feet, the simulator should have the following essential feature (Kinesitherapy for patients with spinal paraplegia. L. Potekhin. A manual for doctors, methodologists and physical therapy instructors, Novokuznetsk, 2002), namely, it should allow provide free passive movement of the feet due to the short-term use of hand power and the presence of an intermediate energy storage.

The proposed simulator has the mentioned essential feature.

This is achieved by using the flywheel as an intermediate energy storage device and a manual drive to force the rotation of the flywheel and swing the plate to set the legs.

The technical result of the invention is to increase the efficiency of use by providing the possibility of free passive movement of the feet with short-term use of the strength of the patient’s hands.

The specified technical result is achieved by the fact that the known simulator for restoring the motor activity of the feet, comprising a fixed plate, a movable plate pivotally connected to it for mounting feet, on which a handle for manually swinging it is fixed, according to the invention, has a flywheel horizontally mounted on a fixed plate for energy storage associated with the possibility of rotation with a manual drive and through a crank gear with a movable lever, which is pivotally connected to the plate for installation stop, the arm is reinforced at the center of the movable plate.

The invention is illustrated by drawings, where

figure 1 shows a General view of the simulator from the side;

figure 2 shows a General view of the simulator from above.

The simulator is a fixed plate 1, on which is mounted a movable plate for installing legs 2 using a swivel plate 3.

To provide additional intermediate energy storage on a fixed plate, a flywheel 4 shaft is installed, on which a flywheel 5 is mounted.

To ensure forced rotation of the flywheel and rolling of the movable plate for installing legs due to the strength of the hands, a manual drive is additionally installed. It is a crank gear connected to a flywheel, namely a crank 6 connected through a hinge of a crank 7 to a connecting rod 8, which, in turn, is connected through a hinge of a connecting rod 9 to a slider 10 mounted on a fixed plate with a guide 11 and having a hinge 12 slider. The crank transmission through the hinge of the slider is connected to the lever 13, which is connected through the hinge of the lever 14 to the upper edge of the movable plate for installing legs. The handle of the manual drive 15 is fixedly fixed to the middle part of this plate.

The general cycle of the movement of the feet on the simulator is as follows. At the initial moment, the force of the hands creates a reciprocating movement of the handle 15, which leads to the swing of the plate to install the legs and feet attached to it. Due to the lever 13, the slider 11, the connecting rod 8, the crank 6 and the intermediate joints 14, 12, 9, 7, a rotational movement of the flywheel 5 is created. In this case, the flywheel accumulates excess energy due to its rotation. Then the handle 15 is released and the swing plate for installing the legs continues due to the energy accumulated by the flywheel. As the energy of the flywheel is consumed, the swing of the plate for installing the legs and, therefore, the foot slows down. By applying very little additional effort to the feet through the calf muscles of the legs, the patient can somewhat slow down the decrease in the rotation speed of the mechanism, which leads to a gradual improvement in the motor activity of the feet. After the flywheel is almost completely stopped, the patient again with his hands reports the reciprocating movement of the handle 15, and the cycle repeats.

The invention can be implemented by manufacture in a specialized enterprise.
