Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for measuring a transdermal permeation loss and a skin management system using the same,

More particularly, the present invention relates to an apparatus for measuring the amount of percutaneous water loss, and more particularly to a method and apparatus for measuring the amount of percutaneous water loss by automatically correcting a measured value measured according to a slope at the time of measuring the amount of water loss, And more particularly, to a skin permeation measurement apparatus and a skin management system using the same.

The skin of the human body performs important functions such as prevention of intrusion of bacteria and harmful substances from the outside, waterproofing, and temperature control. This function is called skin barrier function, and the amount of transdermal water loss is an indicator of the level of skin barrier function.

In the case where the function of the skin barrier is deteriorated, that is, when the transdermal water loss is large, penetration of the external allergen through the skin becomes easy, and various skin diseases such as atopic symptoms are caused. Therefore, It is especially important. The prevalence of atopy is high in newborns with high transdermal water loss, and the prevalence can be halved by proper moisturizing control.

Generally, the horny layer of the skin surface has a water content of about 20 to 70%. However, the air content of the air is lower than that of the skin, so the moisture on the surface of the skin evaporates and diffuses into the air. Conventionally, an open-type or a closed-type chamber is placed on the skin, and the humidity that is changed when the moisture on the surface of the skin is evaporated is measured in the chamber to measure the amount of transdermal water loss. Specifically, when an open-type or closed-type chamber is placed so as to cover a certain area of skin, skin moisture is evaporated in the chamber and diffused in the air. At this time, the rate of increase in humidity in the chamber is measured to detect the amount of percutaneous water loss do.

However, in the methods of measuring percutaneous water loss according to the related art, there is a problem that the reliability of the measurement results deteriorates as the pressure inside the close chamber changes.

Specifically, since human body temperature or skin temperature is maintained higher than ambient atmospheric temperature, the temperature inside the chamber is increased when the close chamber is positioned so as to cover the skin of a certain area in order to measure the water loss amount. Since the convection phenomenon occurs in which the air having a low density including a large amount of moisture heated by the skin temperature rises in the close chamber, when the transdermal water loss is measured, the humidity or the transcutaneous water measured according to the inclination or angle of the close chamber The reliability of the loss was inevitably lowered because the error rate was high and the accuracy was low.

In the past, the problem has been solved by training how to use it. However, this method of teaching how to use is not very convenient or convenient for general users who are not experts. Therefore, there is a need for a solution that can be solved more directly than an educational method.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a configuration diagram of a transcutaneous water loss measurement apparatus capable of performing a slope correction according to an embodiment of the present invention. FIG.

1, the apparatus 100 for measuring transdermal water loss according to the present invention is configured in the form of a closed-type cylindrical chamber having one side opened for contacting the skin to measure moisture loss and another side closed, The moisture content and moisture evaporating from the surface of the skin connected to the one side are detected and analyzed on the closed side of the other side to measure the amount of water loss percutaneous. At this time, the transdermal water loss measuring apparatus 100 corrects the transdermal water loss value measured according to the inclination and the measurement angle of the moisture content and the humidity, and outputs the corrected value.

Generally, the moisture content of the stratum corneum constituting the surface of the skin is about 20 to 70%, but since the air has a lower moisture content than the skin, the moisture on the surface of the skin evaporates and diffuses in the air. Thus, when a part of the skin to be measured for moisture loss is covered with the open face of the closed chamber type transdermal water loss measuring device 100, skin moisture is evaporated in the covered inside and diffused in the air. At this time, the increase rate of the humidity in the chamber is measured to detect the amount of percutaneous water loss.

When a part of the skin is covered with the apparatus 100 for measuring the loss of the closed-type percutaneous moisture loss, a convection phenomenon occurs in which a low density air containing a large amount of moisture heated by the skin temperature rises in the close chamber, The humidity and the amount of transdermal water loss measured according to the angle at the time of measurement increase the error rate. In order to prevent the occurrence of such an error, it is possible to reduce the error rate by correcting the value of the transdermal water loss measured according to the self-tilt after self-detecting the amount of water evaporated on the skin surface and the inclination of the close chamber during humidity detection . The amount of percutaneous water loss measured by reducing the error rate is transmitted as data and transmitted by near-distance / long-distance wireless communication, and the user can share and confirm the percutaneous water loss amount information converted into data by a mobile communication device such as a smart phone.
