Description

This useful model relates to medicine and can be used as a simulator for the hand, which can be used for therapeutic or orthopedic purposes for the rehabilitation of patients with damaged musculoskeletal system. This useful model can be used as a tool for the psychomotor development of children, and as a sports equipment. It can be especially useful for the development of a combination of motor processes and related physiological and psychological phenomena in pediatric psychotherapy and neurology for patients who have had a heart attack during rehabilitation.

Recently, pillows, rollers and the like, filled with organic natural components, have been widely promoted and used for preventive and therapeutic purposes.

Known utility model of the Russian Federation No. 11091, IPC A63H 3/02. This device has a shell made of synthetic material, which provides the ability to connect the butt joints of the shell under the action of heat. The shell is made of at least one piece of fabric material. The shell is filled with filler made of light and elastic fibrous and / or porous or spongy material.

The disadvantage of this device is that the shell is made of synthetic material, which adversely affects children. In addition, such a device poorly develops the motor skills of the hands of children.

Known utility model of the Russian Federation No. 20238, IPC A61H 1/00, A63F 9/00. This device is designed to develop motor skills. It contains a shell with a filler. The shell is made of natural fabric material. The filler is an organic natural component, which can be buckwheat husk, wood balls, minerals.

This utility model is selected as a prototype, which has significant drawbacks. It is difficult to use for the development of hand motor skills in children. This is due to the fact that when it is used by children, the filler creates a tough effect on the fingers, because the filler is buckwheat husk, wood balls, minerals. They easily penetrate through a shell of fabric material into the fingers of the child's hands.

The objective of this utility model is to create a new device that serves as a simulator and improves the development of motor skills in children’s hands with the achievement of a technical result, namely, giving a smooth and soft behavior of the device under the fingers of a child and the development of their tactile sensitivity.

The problem is solved as follows. In the known device for the development of motor skills of hands, containing a shell made of natural material and a filler mixed in a shell, ACCORDING to the present utility model, the shell is made of three layers, its outer layer is made of leather, the middle is made of doubler, and the inner is made of rubber in the form of a cover, covering a filler of a flour-like composition.

There is an option according to which the flour-like composition is either a homogeneous mixture of flour or starch, or a heterogeneous mixture of these two substances, while the shell has a size and shape that is consistent with the size and shape of the patient’s hand.

Such a new technical solution allows to achieve a technical result: to improve the conditions for the development of motor skills of the hands by developing a tactile feeling in the fingers of patients, the inclusion of biological feedback, since under the action of the fingers the device acquires plasticity while maintaining the acquired shape. This is achieved by the fact that, for example, the flour is located in a rubber ball, which is placed in the outer shell on the inner side having doubler. Doublerin allows the outer shell, which is made of leather, to maintain its shape and prevent the breakthrough of the filler outside the outer shell. Moreover, the skin gradually stretches under the influence of hands, and flour or starch acquire plasticity. As a result, the entire design of the proposed device with an increase in the number of exercises gradually becomes plastic, fits well into the grip of the child’s hands.

The essence of the claimed utility model is illustrated in the drawing, where:

Figure 1 - General view of the device;

Figure 2 - section of the device:

Figure 3 is a cross section of a device:

Figure 4 - cutting the outer shell of the device.

The proposed device consists of a shell made of a three-layer. Its outer layer 1 is made of leather, the middle layer 2 is of doubler, and the inner layer 3 is of rubber in the form of a cover covering the filler 4 of a flour-like composition (Figs. 2, 3). To give the product strength, the inner surface of the outer layer 1 of the shell is coated with doubler 2. It acts as a middle layer. The inner layer 3 is made of an elastic material (latex, rubber) and has the form of a cover. When it is filled with filler 4, for example, flour or starch, or a mixture thereof, which is introduced into the inner case 3 using a special syringe 5 (not shown in the drawing) (FIG. 2), the case is stretched and takes, for example, the shape of a ball. The hole through which the filler 4 is introduced into this case is closed. Usually this filling is carried out under pressure. Then it is introduced into the outer layer and, using the fastener 6, is tightly closed in it. (Figure 1). Usually a tongue is placed under the fastener, for example, made of leather. It overlaps the fastener zone. This increases the strength and reliability of fastening in the shell of the filler. The size and shape of the device is determined by the patient’s hand (not shown in the drawing). Usually this is a ball with a diameter of 150-200 mm. The outer layer is made by cutting flat blanks 7 in the form of, for example, four flap sweep (Figure 4). In principle, such a device can have both oval and round, and in some cases an elepsoobrazny form. It all depends on the structure of the hand.

When starch is used as a filler, when exposed to it, the sound of “creaking” occurs. This causes positive associations in children and, in some cases, serves as an indicator of the effective effect of the hand. In addition, in this case, it is easier to track the reaction of biological feedback when working with the proposed device, which already serves as a simulator. The proposed utility model has passed clinical trials that have shown the following results.

Patients with the following pathology were examined:

1. stroke patients aged 45 to 75 years. 21 people were examined.

2. children with arthrogryposis from the age of 5 to about 12 years. 7 children were examined.

3. children with surgical interventions on the cervicothoracic spine with existing neurological symptoms in the form of upper paraplegia. We examined 7 children aged 10 years to 17 years.

All these results, according to the authors and the applicant, are due to the ability, as noted earlier, under the physical influence of the patient’s hand to form from the simulator convenient for tactile and smooth impact on the skin, and for the arm muscle corresponding figure, slowly and smoothly changing with each new impact on her. In addition, a significant difference of the proposed simulator compared to other carpal expanders is that:

1. The internal composition of the simulator is a compressed flour-like substance, which in its mechanical properties repeats the properties of ductile sculptural clay or plasticine.

2. A leather case creates the necessary resistance for optimal functioning of the muscles involved in fine motor skills during palpation of the simulator and causes pleasant tactile sensations, which in some way causes mechanical and psychological addiction to working with the latter.

With other available expanders, such a striking therapeutic effect, especially in children, did not work due to the lack of similar physical properties.

Children when working with the proposed device showed a greater interest in classes than when training with other simulators. This is due to the texture of the leather case, which is so close to us in nature and the human genetic need to shape the world around us through our own hands.
