Abstract

FIELD: medicine.

SUBSTANCE: invention refers to restorative medicine, and can be used for treating the effects of traumas and diseases caused hand and finger dysfunctions. A hand mechanotherapy apparatus comprises a base whereon a horizontally mounted rotatable cylinder and a block attachment. The block attachment accommodates two feet coupled at the top with a crossbeam whereon there are mounted five guide pulleys for elastic bends one ends of which are fixed on a horizontal axis established on the base, and the others have finger loops. The base integrates two side blocks fixed each of which has mobile and motionless portions. The mobile portion is rotatable round a vertical axis, and comprises an elastic band with a finger loop at a free end the other end of which is fixed on the motionless portion. The base represents a sliding platform length-adjustable by means of a driving screw. The feet of the block attachment are telescopic and height-adjustable by latches inserted in through holes of the feet.

EFFECT: enhancement ensured by adjustment attachments for various sizes of hand and fingers.

Description

The invention relates to regenerative medicine and can be used to treat the effects of injuries and diseases leading to impaired functions of the hand and fingers.

There are a large number of devices for restoring the functional activity of fingers, which provide active-passive development of movements in the joints of the fingers.

Known mechanotherapeutic apparatus for the brush (RU 2033128, IPC A61H 1/2, publ. 04/20/1995), which has a base with side racks mounted on it and a central rack. Thrust handles with protruding threaded ends are attached to the side posts to fix the locking nut of the plate, in the slot of which a massage roller is installed. A gear box is mounted on the central rack, made in the form of a gear pair with output shafts, at the ends of which L-shaped handles are installed. The loading element is a rod, at one end of which a thread is cut to move goods, and on the other there is a groove for installation on one of the shafts with a locking screw.

This unit is bulky and complex. In addition, it has limited functionality, since it does not provide all kinds of finger movements.

Known mechanotherapeutic apparatus for the fingers of the brush in the form of a block device, in which an elastic tape is located, one end of which is fixed, and the other has a fabric loop for the finger (Kaptelin A.F. Restorative treatment for injuries and deformations of the musculoskeletal system. - M., 1969, p. 120-121). This unit provides metered resistance to finger movement. Its disadvantage is that the exercises are performed with only one finger and only the strength of the muscles of the flexors of the fingers is trained.

Closest to the proposed is a mechanotherapeutic apparatus for fingers of the hand (RU 56179, IPC A61H 1/02, publ. September 10, 2006), containing a base on which a cylindrical roller is horizontally mounted for rotation and a block device is installed, which includes two racks connected in the upper part by a crossbar, on which there are five guide blocks for elastic tapes, some ends of which are fixed on a horizontal axis mounted on the base, while others have loops for the fingers, in addition, two lateral blocks are fixed to the base, each having a movable and fixed part, the movable part being able to rotate 360 ° about a vertical axis and there is an elastic tape with a loop for the finger on the free end, the other end of which is fixed on the fixed part.

A disadvantage of the known apparatus is the limited functionality that does not allow it to be used for training hands and fingers of different sizes, for example, for an adult and a child, a man and a woman.

The objective of the invention is the expansion of functionality due to adjusting devices for different sizes of brushes and fingers.

The problem is solved by a device for mechanotherapy of the brush, containing a base on which a cylindrical roller is horizontally mounted for rotation and a block device is installed, which includes two racks connected in the upper part by a crossbar on which there are five guide blocks for elastic bands, one ends which are fixed on a horizontal axis mounted on the base, and the others have loops for the fingers, in addition, two side blocks are fixed on the base, each of which x has a movable and fixed part, the movable part being made to rotate 360 ° around the vertical axis and there is an elastic tape with a loop for the finger on the free end, the other end of which is fixed to the fixed part, in which, unlike the prototype, the base is made in the form of a sliding platform with the possibility of adjusting its length by means of a drive screw, and the racks of the block device are made telescopic with the ability to adjust the height by means of clamps, are inserted through-hole racks.

The invention is illustrated in the drawing, which shows a General view of the device. The device comprises a base 1 in the form of a sliding platform, a cylindrical roller 2, mounted on the base for rotation, a block device comprising two telescopic racks 3 connected in the upper part by a crossbar with five guide blocks 4 for elastic bands 5. One ends of these tapes are fixed on the horizontal axis 6 mounted on the base 1, and the other ends have loops 7 for the fingers. In addition, two side blocks are fixed on the base, each containing a movable part 8 with a short elastic tape 9 located therein and a fixed part 10 in which the end of this tape is fixed. The cylindrical roller 2 is designed to support the hand, as well as to relax and rest the muscles of the hand in the pauses between exercises. The base is moved apart on the guide pins 11 with the drive screw 12 so that its length can vary depending on the size of the brush and fingers.

Using the device perform the following exercises.

1. The rotation of the cylindrical roller with fingers away from you and to yourself;

2. Exercises on the block device (with the brush resting on a cylindrical roller):

- bending of I-II-III-IV-V fingers with the possibility of simultaneous and separate for each finger to perform movements;

- extension of I-II-III-IV-V fingers with the possibility of simultaneous and separate for each finger to perform movements;

- opposition of the first finger;

- opposition of the V finger.

When bending the fingers, the elastic bands 5 are fixed on the horizontal axis 6 and are thrown through the guide blocks 4.

The extension of the II-III-IV-V fingers is carried out by tensioning the elastic bands 5 fixed on the horizontal axis 6, while they are not thrown over the crossbar connecting the racks 3. The extension of the I finger is carried out using an elastic tape fixed to the fixed part 10 of the side block. To contrast the I and V fingers, the elastic bands are fixed and transferred through the moving parts 9 of the side blocks.

The implementation of the base 1 in the form of a sliding platform allows you to change its length, in accordance with the size of the brush and fingers. The execution of the racks 3 adjustable in height allows you to adapt the device for different lengths of the fingers.

The proposed method is used in complex rehabilitation treatment in 172 patients with injuries of the upper extremities - with the consequences of damage to bones, nerves, tendons and muscles. All patients achieved good and satisfactory results. Studied long-term results from 3 to 5 years. They indicate a steady preservation of range of motion and muscle strength in damaged limbs.

Thus, the proposed mechanotherapy apparatus provides the possibility of various movements (flexion, extension, contrasting and muscle relaxation) for one, several or all fingers of the hand with a dosed load and regulation for different sizes of the hand and fingers.
