Description

Skin condition measuring apparatus {Skin condition measuring apparatus}

The present invention relates to a device that enables to measure and monitor the condition of the skin.

In general, there are sebaceous glands that make sebum in the pores of the skin, and under normal conditions, the sebum is gently ejected through the pores to form a sebaceous membrane, which is a natural protective film of the skin. However, when the sebum is secreted too much, for example, due to a misalignment of hormones, it becomes hard as it oxidizes in contact with the air and blocks pores. If sebum is continuously secreted in this state, sebum and keratin are mixed in the pores to form a lump, which is an early stage of acne. In addition, there is a bacterium called acnes, which lives on the sebum secreted from the pores as a nutrient, and when the sebum in the pores blocked by the feces is oxidized into fatty acids, the skin eventually becomes inflamed.

However, this bacterium has the property of emitting light in response to light such as ultraviolet rays. Therefore, the light emission characteristic of the affected part is used as a principle of the device for measuring the condition of the skin.

Conventionally, as a device for measuring the skin condition using such characteristics, a method of allowing a patient's face to be put in a black box and irradiating ultraviolet rays over the entire face to observe the emission state appearing on the skin from the outside.

However, the conventional skin condition measuring apparatus has a problem that it is difficult to observe the exact skin color of the patient because the insufficient care for the illumination, the illumination was not appropriate.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a skin condition measuring apparatus that can measure the skin condition of a patient more precisely and safely with a simple structure.

Skin condition measuring apparatus of the present invention for achieving the above object, the mobile camera unit for irradiating light to a local site of the skin and measuring the site to be tested; A monitor for outputting an image photographed by the camera unit; And a cable connecting the camera unit and the monitor.

The camera unit may include a first polarization filter, a first polarization filter for polarizing light emitted from the first light emitting diode, and a first polarization filter at the first light emitting diode. A second polarizing filter having a polarization angle of 90 degrees with respect to the first polarizing filter and polarizing the light reflected after being irradiated and directly irradiated to the inspected part by the second light emitting diode, and the second polarizing filter; It is preferable to include an imaging lens for focusing the light passing through the polarization filter, and an imaging device for condensing the image formed by the focusing lens.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a skin condition measuring apparatus according to the present invention.

Referring to the drawings, a camera unit 10 for irradiating light to a local part of the skin and measuring a site to be inspected, a monitor 20 for outputting an image photographed by the camera unit 10, and a camera unit 10. And a cable 30 for connecting the monitor 20 to the monitor 20.

The camera unit 10 is a small mobile device that allows the user to observe the skin condition by irradiating light only on a local part to be irradiated. Therefore, the inspector grabs the camera unit 10 as shown in FIG. 4 and photographs while moving the inspecting part of the examinee up and down to observe the image appearing on the monitor 20 every time. Reference numeral 10a denotes a power switch, reference numeral 10c denotes a preliminary switch for viewing still images, reference numeral 10b denotes a mode switching switch to be described later, reference numeral 31 denotes a power connector, and reference numeral 32 denotes a video output. Each terminal is shown.

Figure 2 shows the internal components of such a camera unit 10. As shown, the camera unit 10 includes first and second light emitting diodes 11 and 12, first and second polarization filters 13 and 14, an imaging lens 15, and an imaging device 16. Doing. The first and second light emitting diodes 11 and 12 may be light emitters that emit visible light. The light emitted from the first and second light emitting diodes 11 and 12 is irradiated to the inspected part, and the light emitted from the first light emitting diode 11 is transmitted to the inspected part through the first polarization filter 13. The light emitted from the second light emitting diode 12 is irradiated to the inspected portion directly through the hollow 11a without passing through the first polarizing filter 13. Thereafter, the light reflected from the inspected part passes through the second polarization filter 14 having the polarization angle rotated 90 degrees with the first polarization filter 13, and then passes through the imaging lens 15 and the imaging device 16. Will be reached.

This skin condition measuring device has a circuit connection structure as schematically shown in FIG.

In this structure, the first and second light emitting diodes 11 and 12 can be used in different observation modes.

First, when the second light emitting diode 12 is used, the emitted light is directly irradiated to the inspected part and then reflected to pass through the second polarizing filter 14 and the imaging lens 15 to reach the imaging device 16. This is used when observing the general skin texture of the general through the monitor 20.

However, when the first light emitting diode 11 is used, after the emitted light is attenuated by about 40% through the first polarizing filter 13, it is irradiated to the subject to be inspected, and thus the spots formed by inflammation of the skin or deposition of melanin pigment and The same effect can be seen to stand out. In addition, since the light whose constant direction is passed through the irradiation and reflection process is sent to the imaging device 16, the surface of the skin can be observed with the uniform light through the monitor 20. Therefore, when it is desired to observe the affected part accurately, the first light emitting diode 11 is used.

The use of the first and second light emitting diodes 11 and 12 can be selected by operating the mode conversion switch 10b attached to the camera unit 10. Therefore, according to such a configuration, it is possible to measure the skin condition in accordance with a desired condition by dividing the mode into a case where one wants to see the skin texture of a general skin and when one wants to accurately look at the affected part.

As described above, the skin condition measuring apparatus according to the present invention provides the following effects.

First, by configuring the camera unit as a small mobile that can be moved by the user holding the hand, the subject can be observed while freely moving the area to be observed while lying comfortably.

Second, since the equipment is miniaturized, it is easy to move and store.

Third, by implementing an optical system capable of mode conversion using a plurality of light emitters and polarizing filters, it is possible to selectively perform overall observation of skin texture or intensive observation of affected areas. And by using a some filter and adjusting illumination intensity suitably, the exact skin color of a patient can be observed.

Fourth, since the light is irradiated only to the local region to be measured, it is possible to prevent deterioration of the skin due to overexposure.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims.
