Abstract

A device for non-invasive diagnostics of the mechanical parameters of the human skin, including a body, an elastic guide, on the free end of which there is a firing pin and a displacement sensor, characterized in that the elastic guide is fixed in a controlled mechanical carriage, and the firing pin is made in the form convex hemisphere.

Description

The utility model relates to devices for identifying biomechanical parameters of the human skin with a non-destructive method and can be used in medicine and cosmetology, in particular to determine the effectiveness of individual therapy.

A device for determining the mechanical properties of the skin of a person by a non-destructive method (see patent No. 24786, published 2002.08.27), consisting of a housing and a rocker mounted in it with a sensor on one side and a counterweight on the other.

The disadvantage of this device is the low accuracy of the measurements.

Closest to the claimed is a device for determining the elastic and dissipative properties of the human skin non-destructive method (see patent No. 29841, published 2003.06.10), consisting of a housing and a guide in the form of an elastic beam, at the end of which there is a firing pin with a mounted sensor displacement and sensitivity adjustment screw in the housing.

The disadvantage of these devices is the lack of practical measurement accuracy.

The objective of the utility model is to increase the accuracy of measurements.

The problem is achieved in that in the device for determining the elastic and dissipative properties of the human skin non-destructive method, consisting of a body and a guide in the form of an elastic beam, at the end of which there is a firing pin with an installed displacement sensor, the elastic guide is fixed in a controlled mechanical carriage, and the firing pin is made in the form of a convex hemisphere.

Distinctive features in the claimed technical solution were not identified when studying this and related areas of technology.

The combination of the claimed features ensures the achievement of the objective of the utility model - improving the accuracy of measurements.

Figure 1 shows a General view of the proposed device.

The device consists of a housing 1, in which a mechanized carriage 2 is placed for moving a cantilever-fixed elastic guide 3. At the free end of the guide there is a firing pin 5, made in the form of a convex hemisphere, with a magnetic field sensor fixed to it 6. Also, a constant magnet 7. A trigger electromagnet 4 is mounted above the guide, controlled by a control system including a microcontroller 8 and an amplifier 9.

The device operates as follows. After installing the device on the surface of the skin (not shown in Fig.), The microcontroller 8 supplies a control signal to the mechanized carriage 2, which lowers the elastic guide until it is completely in contact with the skin surface. Then, an electric voltage is applied to the starting electromagnet 4, as a result of which the elastic guide 3 is bent and the firing pin 5 with the sensor 6 is attracted to its highest position. Next, a signal is sent to turn off the starting electromagnet 4. As a result of a direct central impact of the firing pin 5 on the studied area of the skin 11, an oscillatory process occurs, which is detected by the magnetic field sensor 6, the signal from which is recorded by the microcontroller 8 as a function of voltage versus time. The spherical shape of the striker provides a direct center hit. The microcontroller 8 processes the received signal, determining the amplitude and frequency of oscillations, and according to a special algorithm calculates the coefficient of elasticity and viscosity of the studied area of the skin.

Using the proposed device can significantly speed up the process of diagnosis, not only in medical institutions, but also with a high degree of accuracy to individually monitor the effect of exposure to various creams and ointments.
