Abstract

FIELD: medicine.

SUBSTANCE: thermoelectric device for thermal cosmetic procedures includes a high thermal conductivity base as a mask repeating the contours of a human face with holes in the area of eyes, nose and mouth. From the side of contact with the face surface, the base has a thin silicon layer, and is connected with affecting thermocouples junctions on the opposite side. The thermocouples are connected to a programmable DC power source that implements various operation modes. The reference thermocouples junctions are coupled with a radiator. The base is provided with a fastener for dense device fixation on the human face, it is a sealed container filled with granulate and formed by a solid film from the side of contact with the human face surface and by a flat rigid plate from the opposite side. The plate and granulate are made from a material with high thermal conductivity. The radiator is configured as a hollow metal box allowing to fit a heat accumulator precooled by an external refrigeration unit during operation.

EFFECT: increased efficiency of thermal cosmetic procedures due to consideration of individual human face geometry.

Description

The invention relates to medicine and is intended for thermal cosmetic procedures, mainly on the face of a person.

The prototype of the invention is the device described in [1]. The device contains a flexible base of highly heat-conducting material, made in the form of a mask that follows the contours of a person's face with holes in the eyes, nose and mouth. The lateral surface of the base has protrusions bent at an angle of 90 ° to the base. The protrusions with the provision of tight thermal contact are associated with the acting junctions of thermoelements (FC). Support junctions of TE contact with an air radiator. On the surface of the base there is a thin silicone layer that prevents mechanical damage to the skin of the face when in contact with the device. FCs are connected by electric wires to a programmable direct current source that implements various modes of their operation (cooling, heating, their alternation). The base is equipped with a mounting device for tightly fixing the device to the person’s face.

The disadvantage of this device is the impossibility of taking into account the individual geometry of the person’s face and, as a result, the insufficient efficiency of thermal cosmetic procedures.

The aim of the invention is to increase the efficiency of thermal cosmetic procedures by taking into account the individual geometry of the human face.

The goal is achieved in that the base is made in the form of a sealed container formed on the side of contact with the surface of the person’s face with a strong film and on the opposite side with a flat rigid plate filled with granulate. The plate and granulate are made of a material with a high coefficient of thermal conductivity. The radiator is a hollow metal box in which a heat accumulator pre-cooled by an external refrigeration unit is installed during operation of the device.

The block diagram of the device is shown in FIG. one.

The device comprises a base 1, made in the form of a mask repeating the contours of a person’s face with holes 2 in the eye, nose and mouth. The base is a sealed container formed on the side of contact with the surface of a person’s face with a strong film (plastic or cloth) 3 and on the opposite side with a flat rigid plate 4 filled with granulate 5. The plate 4 and granulate 5 are made of a material with a high thermal conductivity (for example, copper or aluminum). Thermoelectric elements 6 are installed on the outer surface of the plate 4 with good thermal contact, the supporting junctions of which are connected to the radiator 7. The radiator 7 is a hollow metal box into which a heat accumulator pre-cooled by an external refrigeration unit is installed (for example, an all-metal bar made of copper or aluminum). On the outer surface of the film 3 in contact with the person’s face, there is a thin silicone layer 8 that prevents mechanical damage to the skin of the face when in contact with the device. Thermoelectric elements 6 are connected by electric wires to a programmable direct current source that implements various modes of their operation (cooling, heating, their alternation). The base 1 is equipped with a mounting device 9 for tightly fixing the device on the person’s face.

The device operates as follows.

Before starting the procedure, the device is fixed on the person’s face, subject to thermal influence, ensuring tight contact of the silicone layer 8 located on the surface of the film 3 of the base 1, taking into account its morphological features due to the elastic properties of the film 3 - granulate 5 system and the presence of a fastening device 9. Procedure begins with the inclusion of a programmable power supply, according to a given program, which supplies electric current with the required magnitude and polarity of thermoelectric elements 6 placed on the plate 4. The dose and duration of heat exposure is determined by the cosmetologist, he also carries out ongoing monitoring of the patient's condition. Radiator 7 is designed to remove excess heat from the reference junctions of thermoelectric elements 5, conjugated with the plate 4, while cooling the face.
