Description

A device for restoring the efficiency of the hand can be used in the field of medicine, and in particular for restoring the brain activity of a patient after a stroke, through the impact on the hands of gymnastics. The treatment of such patients involves the use of various methods of treatment, such as drug therapy, massage, acupuncture, and their combined use, as well as various means aimed at both restoring motor function and restoring brain activity, which is carried out through passive and active gymnastics. .

A device is known for the prevention and treatment of hand contractures in children after surgical treatment of congenital syndactylia [Useful model of the Russian Federation No. 55589 class. A61H 1/00, publ. 27.08.2008], containing a working pneumatic chamber, to which a rubber cylinder is attached, a source of compressed air with a control valve and a pressure gauge, it is also equipped with a means for attaching a hand in the form of an elastic mesh tubular bandage. The device is used as follows: an elastic working pneumatic chamber is inserted into the patient's hand, then the elastic working pneumatic chamber is fixed over the arm with an elastic bandage, then air is pumped into the chamber with the help of a pneumatic balloon and the fingers of the hand begin to unbend. Then the valve is opened and the air is released from the chamber, bending occurs in the joints of the fingers, then the procedure is repeated

The disadvantages of the known device include the fact that the fastening of the fingers used does not allow you to control their movement within the specified limits due to the lack of an individual fastening on them. In this device, there is no possibility of access to an open palm for acupuncture manipulations.

A device for forced recovery of the hand is known, including a compressor, a platform, and an elastic working chamber for air with a glove attached to it, while the platform at maximum expansion switches the air supply lever [Utility model RF No. 79778 IPC A61H 1/00 publ.20.01 .2009].

The disadvantages of the known include the difficulty of putting on a glove on the patient's immobilized hand, there is no provision for changing the glove for the right or left hand, and there is no adaptation of the glove to the size of the hand. The complexity of the product itself due to the presence of the glove itself for attaching the hand. It is not possible to carry out acupuncture procedures on an open spastic arm.

A device is known that contains an inflatable working chamber made of an elastic material, to which an injection cylinder is attached through an elastic tube, in particular a pear (which can be replaced by a source of compressed air), made of an elastic material, made with the possibility of manual compression for air injection, similar to air injection into tonometer cuff. A non-return valve and a control shut-off and bleed valve are built in series between the cylinder and the inflatable working chamber, on which a stylized six-fingered glove with six finger compartments is fixed, which can be worn with both left and right hands. The compartments for the fingers are made through. The inflatable working chamber is equipped with a fabric cover made of dense fabric, on which a glove is fixed (sewn), which is equipped with an elastic strap to fix the wrist. For training, put on a glove, fasten the strap on your wrist, close the valve. Using a pear, air is pumped through the tube into the inflatable working chamber until the patient feels the stretching of the muscles of the hand in the glove. Next, they give the hand to get used to the partially extended state of the fingers, then a little more air is supplied and the brush is fully extended. The procedure is carried out several times [Useful model of the Russian Federation No. 133727 IPC A61H 1/00, publ 27.10.2013].

The disadvantages of the known device include the difficulty of putting on a glove on an immobilized hand. The complexity of the product itself due to the presence of the glove itself for attaching the hand, and the attachment of the glove itself to the pneumocapacity case. It is not possible to carry out acupuncture procedures on the open spastic arm due to the presence of a fixing glove that covers it for the most part.

The closest technical solution is a Device for the rehabilitation of patients with spastic hemiparesis [Patent for the invention of the Russian Federation No. 2239405 IPC A61H 1/02, publ. November 10, 2004], which contains an elastic working chamber, to which a rubber cylinder is attached - a source of compressed air with a control valve for pumping air into the elastic working chamber. At the same time, the elastic working chamber is placed in a cover made of fabric (tarpaulin), on which a glove with partially cut off fingers is fixed. The device is used as follows: a glove is put on the patient's hand and air is forced into the chamber using a rubber balloon. The camera, increasing in size, straightens the fabric of the cover and the glove, straightening the hand at the same time. As air is forced into the elastic working chamber, the pressure in it increases, the hand unbends and is fixed on the chamber in a glove with partially cut off fingers.

The disadvantages of the prototype include the difficulty of attaching the device to an immobilized hand (spastic) by putting on a glove. The complexity of the product itself due to the presence of the glove itself for attaching the hand, sewing it, and attaching it to the pneumatic container by means of a cover with a zipper made of tarpaulin-type fabric. It is not possible to carry out acupuncture procedures on the open spastic hand due to the presence of a fixing glove that overlaps the hand for the most part.

The proposed invention solves the technical problem of excluding the fixing glove and the cover on the working chamber in the development of a device for restoring the operability of the hand. The technical problems of expanding access to the surface of the hand for medical procedures, the possibility of using one device for the left and right hands and the possibility of restoring the functionality of the fingers separately, in pairs or in a separate group are being solved. It also solves the technical problem of expanding the arsenal of technical means for restoring the efficiency of the hand, in particular for restoring the patient's brain activity after a stroke, through the impact on the hands of passive and active gymnastics

The device for restoring the efficiency of the hand contains an elastic working chamber, a source of compressed air for it, and air inlet and outlet valves. The working surface of the elastic working chamber is equipped with attachment bases, to which, in the projection of the reduced hand, additional attachments for the fingers and the wrist joint are attached. The bases of the fasteners are made in the form of flattened bulges on the stem, resembling a button on the stem. At the same time, additional attachments of the thumb and little finger are placed at the same level relative to the maximum diameter of the elastic working chamber, and the fingertips are directed towards the maximum size of its diameter. Additional fasteners for the fingers are made with the possibility of changing the size in accordance with the size of the attached finger and wrist joint in the form of ties, straps or elastic rings, which can either be fastened through the holes in them to the bases of the fastenings, or glued to them. The number of additional fasteners, if necessary, you can use more than one.

An example of attaching a hand to an elastic working chamber. The projection of the attached hand (left or right) is placed on the elastic working chamber in such a way that the additional attachments of the thumb and little finger are placed approximately at the same level relative to the maximum diameter of the elastic working chamber. The index, middle and ring fingers, as well as the little finger, are attached with additional fasteners. The fingertips are directed towards the maximum size of the diameter.

The device for restoring the health of the hand works as follows.

Initially, from the compressed air source through the inlet valve, air is supplied to the elastic working chamber. Initially, the air is supplied in a convenient volume, for attaching the patient's hand to the elastic working chamber, using additional fasteners, for example, using straps. At the same time, additional attachment for the fingers is made with the possibility of changing the size in accordance with the size of the attached finger and the wrist joint in the form of ties, straps or elastic rings. The brush can be attached to the elastic working chamber both on the back and on the palm side. After attaching the brush to the elastic working chamber, the air supply to it continues. As a result, the elastic working chamber increases in size, the hand straightens and opens in full and is in this position according to the applied treatment method. At the same time, if there is a medical need, it becomes possible to carry out acupuncture procedures. After the cycle of the extended state of the hand is completed, the air is released through the air release valve, which makes it possible to reduce the load on the hand, and, if necessary, resume the load or remove it completely. At the same time, the developed device allows you to load the fingers individually, as a pair or a group, or the entire hand.
