Description

The invention relates to the field of medical technology, namely to devices for temperature exposure and reflexology, and can be used for reflex improvement of blood and lymph circulation in various organs and the entire body of patients.

Devices are known that make it possible to achieve an increase in the tonic activity of a plurality of thermal and cold receptors in human skin due to the formation of a difference in the heat transfer coefficients of textile strips adjacent to the body due to natural air convection.

Gasanov's therapeutic and prophylactic suit [1] and Gasanov's therapeutic and prophylactic blanket [2] are known, consisting of alternating two types of bands that create a temperature difference in adjacent areas of the body sufficient to cause simultaneous irritation of heat and cold receptors of subthreshold strength under comfortable conditions for the functioning of the body .

The closest solution to the proposed one, chosen as a functional prototype, is a multi-layered medical blanket Gasanov [3], which contains at least two interconnected layers of textile fabric with alternating two types of stripes. When applied to the body, one type of strip prevents, while the other promotes natural air exchange. Lines of strips of connected adjacent layers are arranged at an angle to each other and form sections of the web with different heat transfer coefficients due to the natural movement of air through them at different speeds. With dense application to the body in comfortable conditions, warm and relatively cold points are formed on the surface of the skin, located at a certain distance, where heat and cold receptors are irritated, respectively.

All of these analogues provide an innovative way of stimulating the body, which can be called: "The method of natural multi-point low-contrast thermopuncture."

The essence of the method is explained as follows:

From the level of medical science, the phenomenon of summation in the nerve center is known, about which I.M. Sechenov in 1863. With simultaneous weak excitation of different sensory nerves that transmit excitation to the same nerve center, spatial summation of excitation occurs [4]. The more subthreshold stimuli, the more the mediator is released from the presynaptic nerve endings, and the stronger the reflex response.

In this method, the appearance or absence of a response reflex reaction depends on the threshold level of the body's temperature sensitivity.

The work carried out by the authors and the results of clinical trials of the above analogs showed that the specified method of natural multi-point low-contrast thermopuncture provides the appearance of a response reflex reaction only in about 70% of adult patients, while the reaction is not always sufficiently effective. This is a disadvantage of the chosen functional prototype.

The proposed technical solution involves an increase in the temperature difference of points on the body due to the forced supply of a plurality of air jets to it with a higher and lower temperature in order to increase the effectiveness of the method, which in this case will be called: "Method of multi-point contrast thermopuncture".

Known analogues of devices for influencing human skin directed air flow.

The closest in technical essence to the claimed device is the device for thermal effects on human skin [5] selected as a constructive prototype, containing a blower unit with an air flow rate control unit, an air flow heating unit, an air flow temperature controller and a supply nozzle (hole). air to the human body. The essence of the action of this device is the thermal effect on the reflexogenic zones of a person by conducting thermal acupuncture stimulation with pulses of a heated air flow. The supply of heated air in a pulsating mode allows you to get a difference in volume and, to a small extent, in the temperature of the air delivered to the site of exposure to the skin and cause a slight reflex reaction.

The disadvantage of this device is the weakness and low efficiency of the evoked reflex reaction, tk. it allows you to increase the tonic activity of exclusively thermal skin receptors. The plot of the dependence of the average constant activity of thermoreceptors on the temperature on the skin surface (Fig. 1) shows that thermal receptors are most active at a temperature of 40°C and above, cold receptors - about 25°C.

The objective of the claimed invention is to create a device that provides the use of an innovative method of multi-point contrast thermopuncture by multi-jet supply of air with a contrast temperature to the patient's body in order to achieve a tonic activity of heat and cold receptors close to the maximum.

The technical result of the invention, which consists in eliminating the indicated shortcomings of the functional and structural prototypes, is achieved by the fact that in the air shower device, the impact on the surface of the human body, operating in comfortable conditions for the functioning of the body - at an ambient temperature of 18 ... 24 ° C and normal humidity, containing a blower unit with an air flow rate control unit, an air flow heating unit up to 45 ... 60 ° С, an air flow temperature controller and a watering can (nozzle), the air flow is divided into two parts - heated and unheated, which are supplied to the watering can. The air flow rate control unit has an unheated air outlet to the watering can. The watering can consists of two systems of parallel tubes with holes for air supply in a manner that ensures uniform distribution of heated and unheated air jets in a ratio of 3:1…5:1. The tubes are arranged in an order that provides a minimum obstacle to the removal of air reflected from the body through the annulus.

The totality of all the essential features that determine the composition of the proposed contrast air shower and are its integral parts, allows you to use the air shower as a product for reflexotherapy stimulation of the body by the method of multi-point contrast thermopuncture.

The main characteristics in the proposed air shower are:

- two outlets to the air supply unit to the human body with an unheated air temperature of 18 ... 24 degrees and heated air - 45 ... 60 degrees C in order to achieve a more noticeable contrast temperature on the body;

- the air supply unit to the body is made in the form of a watering can with two systems of parallel tubes with holes for the exit of heated and unheated air to the body;

- the tubes of the heated air system are located behind the tubes of unheated air at a large angle to them in order to provide a minimum obstruction to the removal of air reflected from the body;

- the location of the tubes and the holes in them of the systems of tubes for supplying air to the body are made in such a way that the ratio of heated and unheated air jets is 3:1 ... 5:1.

The invention is illustrated by drawings.

On fig. 1 shows a graph of the average constant activity of skin thermoreceptors versus temperature. [6] It can be seen from the graph that the selected temperature ranges of heated and unheated air provide the necessary increased tonic activity of heat and cold receptors.

On fig. 2 schematically shows the construction of a contrast air shower. The device consists of a blower unit 1, a block for regulating the speed of heated and unheated air flows 2, an air flow heating block 3, a temperature controller for the heated air flow 4 and a watering can 5, consisting of tube systems with holes for supplying heated and unheated air jets to the patient's body. The distances between the tubes and holes, as well as the diameters of the holes, are determined experimentally depending on the operating conditions of the device. For example, they will be different for the immobile and systemically moving body of the patient.

Gasanov's contrast air shower is used as follows. The shower head is installed at the level of the body part of a standing person, which is exposed to air jets with a contrasting temperature. The device is put into operation, the air speed in the streams of heated and unheated air is regulated. The temperature of heated air is regulated within 45…60°С. The patient approaches the watering can at a certain distance, stands in front of it until the onset of a reflex reaction and begins systemic movements, determined by the feeling of the effectiveness of the body's reaction - approaching, turning, lowering, tilting at different speeds and stops. Duration of exposure - as needed, or as prescribed by a doctor.
