Description

The utility model relates to medicine. The elasticity of the skin is one of the main criteria for assessing the biological age of a person and the state of his skin.

It is determined by the method of vacuum cutometry. At the same time, negative pressure is created in the cavity of the special nozzle, and a small area of the skin is absorbed inward. The optical system records the amount of skin deformation under the influence of vacuum and the speed of its return to its original position after unloading. Accordingly, the longer the skin straightens, the less its elasticity. (Kaiz, T.M., Gartstein V. Review of the instrumental assessment of skin; Effect of cleansing products. J Soc Cosmet Chem 1991. July / August; 42: 249-271).

The disadvantages of this method are its low accuracy and reproducibility. This is due to the presence of pores on the skin, which do not allow creating reproducible negative pressure parameters in the nozzle cavity.

In the proposed device for measuring skin elasticity, these disadvantages are eliminated. In it, the deformation of the skin is provided by pressing on it a light ferrite rod, which does not impede the speed of the skin returning to its original position. In this case, the rate of skin return to its initial position does not depend on its relief and the presence of pores.

The device consists of a base (1. Figure 1-3), which is attached to the body using an elastic tape (7. Figure 3) and a latch (8. Figure 3). An inductance coil is fixed at the base (2. Figure 1.2). The inductor (2. Fig. 1,2) is connected to the monitor of the skin elasticity meter (5. Fig. 1-3). Inside the housing of the inductor (2. FIG. 1,2), a rod (3. FIG. 1-3) is inserted containing a ferrite core (4. FIG. 1,2).

The operation of the device for measuring skin elasticity.

After fixing the base of the device for measuring skin elasticity (1. FIG. 1) on the skin (6. FIG. 1) of a person using an elastic fastener tape (7. FIG. 3) and a fastener (8. FIG. 3), a ferrite core ( 4.Fig.1) of the rod (3.Fig.1) is completely in the body of the inductor (2.Fig.1), and is adjacent to the skin surface (6. Fig.1). The monitor measuring the elasticity of the skin (5. Figure 1) converts the inductance of the inductor (2. Figure 1) into the stroke length of the rod (3. Figure 1), which is reset. When you click on the stem (3. Figure 2), its ferrite core (4. Figure 2) presses on the skin surface (6. Figure 2). The skin bends to a certain depth. The ferrite core (4. FIG. 2) exits the cavity of the inductor (2. FIG. 2). In this case, the inductance of the inductance coil (2. Figure 2) changes and the monitor of the skin elasticity meter (5. Figure 2) recounts its change to the stroke of the rod (3. Figure 2) in mm.

Then the force from the rod (3. FIG. 2) is removed and the skin (6. FIG. 2), due to its elasticity, gradually pushes the rod (3. FIG. 2) up. In this case, the ferrite core (4.Fig.2) enters back into the body of the inductor (2. Figure 2). The change in the inductance of the inductor (2. Figure 2) is read by the monitor of the skin elasticity meter (5. Figure 2), which converts it into the dependence of the stroke of the rod (3. Figure 2) on time until the skin relief is completely restored. After that, a signal is sent to end the study.
