Description

The invention relates to hygiene and sanitation, and can be used for the prevention and treatment of diseases of the scalp, with simultaneous hair care. The proposed device provides ultraviolet irradiation of both the head and other parts of the body in order to compensate for the deficiency of vitamin D. The irradiator can also be used to reduce or eliminate pain during migraines, to disinfect, its use can help improve mood and faster cure of colds diseases.

A well-known preventive irradiator is known in which a source of optical radiation and optical fibers that simultaneously perform the functions of teeth are used to have a beneficial effect on the scalp. (See, for example, USSR author's certificate, No. 1341453, IPC F 21 V 33/00, “Hygienic brush”, published on September 30, 1987 in BI No. 36).

A disadvantage of the known irradiator is that, used in it, the only source of optical radiation has a limited purpose.

Closer in technical essence and adopted as a prototype, is a therapeutic and preventive irradiator, made in the form of a comb, containing a housing with an internal cavity and teeth located along the housing. Inside the case, batteries and optical radiation are installed, and the teeth are partially transparent. (See, for example, RF patent No. 2114544, IPC A 45 D 24/10, "Comb for hair", published on July 10, 1998 in BI No. 19).

The disadvantage of the prototype is its narrow functional use as a comb with optical radiation, exclusively for the treatment of the skin of the head. The known irradiator does not solve the problem associated, for example, with a deficiency of ultraviolet radiation and the relief of pain during migraines.

One of the causes of a number of diseases is the low content of vitamin D in the autumn-winter period among residents of the middle strip and northern latitudes, which is associated with the absence of ultraviolet irradiation of the skin. The use of various kinds of special centers for ultraviolet irradiation is associated with a high cost of procedures and time consumption. Therefore, such procedures are not available to the majority of the population. The process of filling the deficiency in ultraviolet radiation should occur immediately at the moment of daily routine combing. It is known that a combination of red, green, and blue provides almost any color. It is also known that a particular color produces a different effect on the physical and psychological state of the body. So irradiation of the head with blue or purple light leads to a decrease in headache. With a cold, blue light, etc. helps.

The problems to be solved by this invention are the prevention and treatment of diseases of the scalp with simultaneous hair care and ultraviolet irradiation in order to compensate for vitamin D deficiency. The universal compact treatment and prophylactic irradiator can also be used to reduce pain during migraines and to obtain one or another color background, which can help to improve well-being with colds and other diseases. It can also be used to care for the skin of any part of the body, such as the face, oral disinfection, etc.

The problem is solved due to the fact that in the well-known therapeutic and preventive irradiator made in the form of a comb containing a housing, an optical irradiation source, partially transparent teeth and a power supply, according to the proposal, the irradiation source is LEDs with different emission spectra, including ultraviolet and infrared.

In a variant of the technical solution, LEDs, mainly with an ultraviolet radiation spectrum, are mounted on the ends of the teeth of the comb.

In a variant of the technical solution, the LEDs are divided into groups and each group is equipped with an alternating voltage generator.

In a variant of the technical solution, the LEDs are powered through a pulse generator.

In a variant of the technical solution, the comb is equipped with a switch that fixes the voltage of the generators at any given level.

In a variant of the technical solution, the comb is equipped with a sensor with a switch that includes a contact in the power supply circuit of LEDs with ultraviolet and infrared radiation spectra when in contact with the surface.

In an embodiment of the technical solution, the comb housing is made in the form of a brush.

In an embodiment of the technical solution, the massage part of the irradiator in the form of a comb or brush is made removable.

The use of LEDs with different emission spectra, including ultraviolet, as an irradiation source, makes it possible to increase the functional properties of the comb, in particular, to provide the user with the opportunity to carry out daily soft ultraviolet irradiation of the scalp. In this case, you can get a daily dose of radiation close to sufficient for the body to produce the required amount of vitamin D. In addition, in living biological tissues of the head irradiated with LEDs, metabolism and hair growth are stimulated, the structure of the scalp improves, dandruff disappears. In addition, ultraviolet radiation helps to cure fungal diseases and destroys a number of parasitic organisms that live on the scalp.

The location of the LEDs with an ultraviolet radiation spectrum at the ends of the teeth of the comb allows to bring the source of ultraviolet radiation to the scalp as much as possible and reduce the loss of radiation in the teeth and eliminate the effect of ultraviolet radiation on the eyes.

The distribution of the LEDs of the visible part of the radiation spectrum into groups equipped with alternating voltage generators allows a wide range of variation of the radiation spectra and radiation intensity and, thus, as if to massage the surface of the skin.

Using a pulsed generator to power the LEDs allows for a deeper penetration of rays into biological tissues and, thus, to provide a better massage effect.

A switch that fixes the voltage of the generators at any given level allows the user to set a specific total emission spectrum, for example blue or cyan. It is known that irradiation of the head with blue or blue allows you to reduce, and sometimes even eliminate the headache, helps with colds. Other colors, such as green or purple, help reduce stress, etc.

The presence of a sensor with a switch installed in the power supply circuit of LEDs with ultraviolet and infrared radiation spectra will allow the inclusion of ultraviolet and infrared radiation only in contact with the scalp. The possibility of uncontrolled exposure is eliminated.

The execution of the body of the irradiator in the form of a brush expands the range of its application.

In the embodiment, when the massage part of the irradiator in the form of a comb or brush is made removable, the range of application of the device is expanded, since it can be used to massage other parts of the body and simply as a source of therapeutic color irradiation.

A universal compact treatment-and-prophylactic LED irradiator based on LEDs consists of a housing 1 (Fig. 1), teeth 2 located along the housing and partially or completely made of radiation-conducting material. The irradiator also has a handle 3. A power source is installed inside the handle 4. The housing can be made either in the form of a hollow tube, or from solid material. The material of the tube or solid body is selected transparent for the visible part of the radiation spectrum and for ultraviolet radiation in the range of 320-340 nm and for infrared radiation in the range of 800-1000 nm. On both sides of the tube (solid case), radiation sources 5, made in the form of LEDs, are installed on the boards. The LEDs 5 are arranged so that the light fluxes from them are directed inside the housing. LEDs have a different emission spectrum, for example red, green, blue, infrared and ultraviolet. Inside the handle, controls 6 are installed with a three-position programmable push-button switch 7 and a push-button switch 8. The entire surface of the housing 1, except for the strip 9 facing the teeth 2, has a reflective coating 10 that directs the light flux into the housing (figure 2). The location of the LEDs on the board is shown in figure 2.

In an embodiment of the technical solution, emitters 5 are installed along the housing 1 (Fig. 3) so that their light fluxes are directed towards a strip (not indicated) that transmits the radiation flux.

In an embodiment of the technical solution, part of the LEDs 5, mainly with an ultraviolet (5i) emission spectrum, is located at the ends of the teeth 2 (Fig. 4).

In an embodiment of the technical solution, the irradiator comprises a sensor with a switch 11 that is turned on when it contacts the surface (Fig. 5). The sensor element of the sensor can be performed, for example, based on a capacitor.

In a variant of the technical solution, the irradiator body is made in the form of a brush 12 (Fig.6).

In a variant of the technical solution, the massage element is made removable, in the form of a hollow tube 13, worn on the housing 1 (Fig.7). The tube may have teeth, like a crest (Fig. 8), or a coating in the form of a brush (Fig. 9). In this case, the tube 13 and the housing 1 are provided with longitudinal grooves and guides (not shown), respectively. The tube 13 has a strip 9 facing the teeth or brush, transparent to the emission spectrum of the selected LEDs.

Electrically, the LEDs 5 built into the irradiator housing 1 are divided according to the radiation spectrum (Fig. 10) into five groups with emission spectra, for example, red (5r), green (5g), blue (5b), ultraviolet (5u) and infrared (5 and). Groups of LEDs with different emission spectra are connected in separate circuits. In each individual circuit, the LEDs are connected in parallel. The power supply circuit of the LEDs of each group has its own voltage generator, respectively, for ultraviolet - 14, for infrared - 15, for red - 16, for green - 17 and blue 18. The total number of LEDs and LEDs in the group depends on the length of the comb and strength the light emitted by each of them. The generators 14, 15, 16, 17 and 18 have a common contact 7a of the three-position programmable switch 7. The generators are also equipped with a switch 8, which fixes the voltage selected by the user according to the color of the total light flux. In the power supply circuit of the generators there is a pulse generator 19, generating electrical pulses of high frequency voltage. In the power supply circuit of the generators 14 and 15 there is a contact 20 connected to the sensor 11, which is switched on when it comes in contact with the surface. In parallel with the pulse generator 19, contact 7b of the three-position programmable push-button switch 7 is turned on.

Generators 12-16 provide various voltage variation graphs U = f (t) for LEDs with different emission spectra. For example, for the generator 14, this graph is indicated by the number 21 (11), for the generator 15 by the number 22 and for the generator 16 by the number 23, for the generator 17 by the number 24 and by the generator 18 by the number 25. In turn, the pulse generator 19 converts the voltage to a series of electrical pulses varying in frequency (Fig. 12) or in width (Fig. 13). The resulting waveform of the radiation pulses during the operation of the pulse generator and one of the generators 14-18 is a set of pulses that vary in frequency and amplitude (Fig.14).

Universal compact treatment and prophylactic LED irradiator operates as follows.

Made in the form of a comb, it is used for its intended purpose for combing hair and massaging the scalp. At the same time, the irradiator is also used as a tool for optical, including ultraviolet, exposure with the aim of preventing and treating hair roots. In addition, ultraviolet radiation helps to cure fungal diseases and has a detrimental effect on microorganisms that often settle on the skin of the scalp.

The irradiator-comb is turned on by pressing the button of the three-position programmable switch 7. In this case, the contact 7a is closed and the power is supplied through the pulse generator 19 and the generators 14, 15, 16, 17 and 18 to the LEDs 5u, 5r, 5g, 5b and 5i, emitting in the ultraviolet, visible and infrared ranges of the spectrum (figure 10). The pulse generator converts the supply voltage into a series of pulses (Fig.12 or 13), and the generators change their voltage depending on time according to various laws. The resulting waveform of the voltage pulses will be similar to FIG. The dependence between the magnitude of the current flowing through the LED and the light flux Φ emitted by it is almost linear. In this case, according to the graphs, the luminous flux of each group of LEDs also changes. Different in spectrum and frequency, smoothly varying in amplitude light fluxes act differently on the scalp, providing a favorable soft massage of the hair roots. The pulsed nature of the change in radiation contributes to a deeper penetration into the surface of the skin and provides a better massage effect. In addition, the resulting luminous flux is created, determined by the summation of the three components, red green and blue. Changing the luminous flux of the component provides a smooth transition from one color to another. The pulse mode of the irradiator can be replaced by a smoothly changing luminous flux. To do this, press the button 7 of the three-position programmable switch a second time, which will lead to the closure of contact 7b. When this power is supplied to the LEDs, bypassing the pulse generator 19, through the generators 14-18. This leads to the fact that the total color of the radiation is continuously changing. Single-color mode is possible. To do this, press the button switch 8. In this case, the voltage change on the generators is stopped and the radiation color selected by the user is fixed. Stopping, for example, in blue, the user of the comb has a therapeutic effect on the body. The headache decreases or completely disappears, the common cold is cured. The choice of color and exposure time depend on the individual characteristics of the consumer and can be dictated by the experience gained when using the comb.

The inclusion of ultraviolet and infrared radiation can be done by pressing the teeth of the comb to the scalp. In this case, the sensor 11 is activated and the switch 20 is turned on, forming a power circuit for ultraviolet and infrared LEDs. Irradiation with the ultraviolet and infrared range is also possible both in pulsed and in smoothly changing versions of the irradiator. So in the process of caring for the hair of the head, at the same time, massage occurs, exposure to a light field and ultraviolet irradiation of the skin. All this favorably affects the hygienic condition of the scalp, contributes to physico-chemical changes, such as the excited state of molecules, coagulation of protein structures, a change in the state of biological tissues, which, ultimately, leads to the healing of the whole organism with additional production of vitamin D.

The composition of the LEDs may also include groups with a different color than specified in the description, for example yellow or blue.

The described action of the irradiator-comb remains the same when the comb is made in the form of a brush. However, the surface of the brush is more developed, which allows you to place more LEDs on it. Therefore, the therapeutic effect of applying the brush will be higher. If the design provides for a removable embodiment (Fig. 8 or 9), the irradiator can be used to massage other parts of the body by exposure only to the light flux.

Such an irradiator can disinfect, for example, the oral cavity, intimate parts of the body, soles of the feet, etc. The irradiator can be used simply as a light source with a changing light color or a constant light color.
