Description

The invention relates to medicine and is intended for cosmetic procedures.

A device for carrying out cosmetic procedures is known, including a feeding tube having a heating element, an applicator head (patent 2428905, published September 20, 2011, IPC A45D 34/00).

The known method is ineffective, because the cosmetic product is applied on the face unevenly. The nutrient is supplied in solid form, which does not ensure the preservation of its quality indicators.

The closest technical solution is a device that contains a massage unit, including a housing where a heat-contact plate, a heat sink and thermocouples (TE) are installed, and means for cooling or heating the heat-contact plate, which includes a direct current source connected via thermocouples to the switching element. The device is equipped with an automatic contrast thermal cycling unit located between the direct current source and the switching element, a holder with an opening for the massage block, and elements for pressing the heat-contact plate to the skin interacting with the holder (RF Patent for invention No. 2047298, published November 10, 1995, IPC A61H 7 / 00, F25B 1/02).

The disadvantage of this device is the impossibility of simultaneous thermal effects on the entire surface of a person’s face, having a certain structure and geometry.

The technical result of the claimed object is to provide the possibility of simultaneous thermal effects on the entire surface of a person’s face in accordance with a certain structure and geometry.

The technical result is achieved by the fact that the heat-contact plate is made in the form of a flexible base of highly heat-conducting material, having the shape of a mask that follows the contours of the face of a person, with holes in the eyes, nose and mouth, consisting of a set of segments with the possibility of adjusting the shape and size in accordance with specific geometric characteristics of the face, while the connection of the stacked segments with each other is done by latches along their lateral surface, free of connecting latches, has protrusions from bent at an angle of 90 ° to the base and associated with ensuring tight thermal contact with the acting junctions of thermocouples, and the supporting junctions are in contact with an air radiator and there is a thin silicone layer on the surface of the base on the face side, while the base is equipped with a fastening device for tightly fixing the device on the face .

In FIG. 1 is a structural diagram of a device that contains a flexible base 1 of highly heat-conducting material (copper or aluminum plate), made in the form of a mask that repeats the contours of a person’s face with holes 2 in the eyes, nose and mouth. The base consists of stacked segments assembled in such a way that it is possible to regulate its shape and size in accordance with the specific geometric characteristics of a person's face. In this case, the connection of the stacked segments with each other is made by one or another type of latches (for example, Click-connection) along their side surface.

The lateral surface of the base 1 formed in this way, free from the connecting latches, has protrusions 3 bent at an angle of 90 ° to the base 1. The protrusions 3 with a tight thermal contact are connected with the acting junctions 4 of the heat cell 5. The reference junctions 6 of the heat cell 5 are in contact with an air radiator 7. On the surface of the base 1 from the face there is a thin silicone layer 8, which prevents mechanical damage to the skin of the face when in contact with the device. TE 5 are connected by electric wires to a programmable DC source (not shown in Fig. 1) that implements various modes of operation of the modules (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 corresponding geometry of the base 1 is selected due to the corresponding connection of the stacked segments among themselves. Then the device is fixed on the person’s face, subject to heat exposure, ensuring tight contact due to the elastic properties of the base 1 and the presence of a fastening device 9. The procedure begins with the inclusion of a programmable power supply unit, according to a given program, which supplies electric power with the required magnitude and polarity of TE 5. Dose and the duration of the heat exposure is determined by the cosmetologist, he also carries out ongoing monitoring of the patient's condition. Air radiator 7 is designed to remove excess heat from the reference junctions 6 TE 5 when cooling the face. The uniform distribution of heat along the base 1 is ensured by the high thermal conductivity of the material from which it is made.

The constructive simplicity of the device, the ability to change modes in a wide temperature range, as well as the ability to accurately fit the geometry of the working surface of the device to the structure of the face will ensure widespread use of the device in cosmetology.
