More particularly, the present invention relates to an apparatus and a method for removing strands of hair from a near-infrared spectroscopy, which are capable of removing the strands of hair and exposing scalp to make a probe come into close contact with the scalp.
Near-infrared light is an electromagnetic wave having a wavelength range (approximately 1.5 to 0.75 μm) in infrared light, which is close to a visible light.
A conventional measuring instrument using such near-infrared light may be configured to include a near-infrared light sensor part having a light emitting sensor and a light receiving sensor, an amplifier, a measurement part, an analog/digital (A/D) converter, a micro controller unit (MCU), and a driver. When the light emitting sensor irradiates a body of a user with near-infrared light under the control of a central processing unit and the driver, a portion of the near-infrared light may be absorbed into the body of the user and the remaining portion thereof may be reflected and collected to the light receiving sensor. The collected near-infrared light may be converted into an electrical signal, and the electrical signal may be amplified through the amplifier, transmitted to the measurement part, and processed in the central processing unit.
However, the removal of strands of hair is very important for equipment which measures a brain activation image using near-infrared light (NIR).

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The removal of strands of hair is very important for equipment which measures a brain activation image using near-infrared light. Since the near-infrared light has very low transmittance with respect to the strands of hair, attaching a light source and a sensor probe to a head without completely removing the strands of hair may cause a big obstacle in extracting of desired signals.
Accordingly, the present invention proposes an apparatus for removing strands of hair and probes in the form of various shapes and thus a signal may be efficiently measured by removing the strands of hair.
Therefore, when scalp is exposed between the strands of hair and a structure of a probe 120, which is in the form of a streamlined shape, is inserted therebetween, the probe 120 may come into exact contact with the scalp with no interference of the strands of hair.
Further, since a sensor 130 configured to receive light should comprise an amplifier circuit stage, it may be configured with a thin printed circuit board (PCB). Here, the sensor 130 has a characteristic in which a horizontal length of a cross section of the PCB is shorter whereas a vertical length thereof is longer, so that the probe 120 accommodating the sensor 130 may be configured with an external structure in the form of the streamlined shape as shown in the drawing. The probe 120 having such a shape may be exactly inserted between the strands of hair which are removed by the headband main body 100.
Referring to
The main body 100 is configured in the form of an arch shape and worn on the head of the user in a manner of a headband.
Further, a plurality of protrusions 110 may be formed at an inner side part of the main body 100 and thus the strands of hair of the user may be arranged when the user wears the main body 100 such that a portion of scalp may be exposed. In other words, when the main body 100 is worn on the head of the user in a manner the same as that of the headband, the strands of hair are upwardly swept and then separated to both sides of each of the plurality of protrusions 110 such that the portion of the scalp of the user may be exposed.
Furthermore, in the main body 100, a plurality of holes may be respectively formed in rear of the plurality of protrusion 110, and the probe 120 may be coupled to each of the plurality of holes in an insertion manner. At this point, a large number of holes are formed at the main body 100 so that a position, at which the probe 120 is coupled to each of the plurality of holes in an insertion manner, may be changed according to a user and the usage.
The probe 120 (or an optical probe) may accommodate a sensor thereinside, and may come into close contact with the exposed portion of the scalp by the plurality of protrusions 110. There is no limitation in shape of the probe 120, but the probe 120 may be preferable to be configured in the form of a streamlined shape so as to come into close contact with the exposed scalp. Here, the probe 120 may be a structure in the form of a cylinder shape, which surrounds a printed circuit board (PCB) including a transimpedance amplifier (TIA).
Further, a plurality of probes 120 may be formed, and each of the plurality of probes 120 may be respectively disposed in rear of the plurality of protrusions 110. Therefore, the plurality of protrusions 110 formed at the main body 100 remove the strands of hair, and each of the streamlined-shaped probes 120 including sensors thereinside is disposed between the removed strands of hair.
Furthermore, the sensors may be respectively accommodated inside the probes 120 and may receive light. Each of the sensors may comprise a PCB in a rectangular shape in which a vertical length is longer than a horizontal length, and the probes 120 may also be configured in the form of a streamlined shape in which a vertical length is longer than a horizontal length. That is, the probe structure in the form of a streamlined shape may be used to correspond to a PCB structure of the sensor so that the scalp may be exposed by removing the strands of hair from a portion of the scalp. Here, the PCB of the sensor may be designed to adhere in close proximity to the sensor for minimizing external noise.
Accordingly, the arch-shaped headband structure configured to remove upper strands of hair of the user is provided at an upper portion of the probe, and the probe is located directly below the headband structure, so that the probe may be disposed at a position at which the headband structure first passes over the strands of hair.
Such a structure may remove the strands of hair and enable the probe to come into close contact with the scalp when the headband structure is worn while sweeping up hair in a direction opposite to the strand of hair, at not only a forehead but also another portion of a head.
A method for removing strands of hair using the apparatus for removing strands of hair from such a near-infrared spectroscopy may comprise steps of wearing an arch-shaped main body on a head of a user and exposing a portion of scalp by arranging the strands of hair through a plurality of protrusions formed at an inner side part of an arch-shaped main body when wearing the arch-shaped main body; and enabling a cylindrical probe to come into close contact with the exposed portion of the scalp.
In the apparatus and the method for removing strands of hair on the scalp using the arch-shaped headband structure, the arch-shaped main body 100 may be used in not only a form integrated with the probe 120 and the sensor but also a form in which the main body 100 and the probe 120 are respectively separately provided to arrange the strands of hair and then the apparatus is worn over the arranged strands of hair.

At least one wedge-shaped surface 220 may be formed at a lower end part of the cylindrical main body. Preferably, two wedge-shaped surfaces 220 may be configured to face to each other. Accordingly, strands of hair may be separated to both sides along the wedge-shaped surfaces 220 and thus a portion of scalp of a user may be exposed, so that the cylindrical main body and the wedge-shaped surfaces may come into close contact with the exposed portion of the scalp.
Further, the wedge-shaped surface 220 is provided in a direction the same as the arrangement direction of the strands of hair and pushed therebetween to expose the portion of the scalp, and the cylindrical main body is rotated to dispose and fix the wedge-shaped surface 220 to be perpendicular to a direction in which the strands of hair are arranged, and thus the head part 210 can be exposed to the outside.
Furthermore, the sensor may be accommodated inside the cylindrical main body and may receive light. Further, the sensor may comprise an amplifier module PCB.

The at least one wedge-shaped surface 220 may be preferably configured in the form in which two wedge-shaped surfaces 220 face to each other, hair may be separated using the wedge-shaped surfaces 220, and the wedge-shaped surfaces 220 may be fixed by being rotated and opening a gap of the separated hair.
In other words, to remove densified strands of hair, the wedge-shaped surfaces are provided in a direction the same as that of the strands of hair and then are pushed and inserted between the strands of hair, and the probe is rotated to provide the wedge-shaped surfaces to be perpendicular to a direction in which the strands of hair are arranged when the wedge-type probe structure, which is pushed and inserted between the strands of hair, is inserted into the strands of hair by a predetermined depth, so that the strands of hair may be fixed in a state of being separated in left and right directions without returning to their original positions.
Such a wedge-shaped optical probe for removing strands of hair may be used in the range capable of covering an entire head.

The main body 310 may accommodate a sensor. Further, the sensor may comprise an amplifier module PCB.
The light guide 320 may be formed at a lower end part of the main body 310, and may be configured with a plurality of threads to which light is transmitted. At this point, the plurality of threads may be configured in the form of a toothbrush shape, and a depression between adjacent threads among the plurality of threads may be formed with a width capable of accommodating strands of hair, thereby coming into close contact with scalp of a user. For instance, a width b of the depression between the adjacent treads may be formed with 0.56 millimeters (mm), and a width a of each of the plurality of threads may be also formed with 0.56 mm.
Further, the light guide 320 may be configured with acrylic optical fiber capable of enabling light to be transmitted, but it has no limitation in material. Here, an outer circumferential surface of the light guide 320 may prevent light from being transmitted, and only a leading end part 321 of the light guide 320 may enable the light to be transmitted.
That is, the light may be incident into the light guide using the acrylic optical fiber without removing the strands of hair.
As is described above, the toothbrush-shaped optical probe 300 for removing strands of hair may push and insert the light guide 320 between the strands of hair as like a toothbrush shape, thereby effectively coming into contact with the scalp.
Further, only the leading end part 321 of the light guide 320 has light transmittance and the outer circumferential surface of the light guide 320 except for the leading end part 321 prevents light from being transmitted, so that light incident into the leading end part 321 may pass the strands of hair to reach the sensor.
Therefore, a structure having a shape capable of pushing and inserting the light guide up to the scalp may be formed by manufacturing the depression that is wider than a thickness of each of the strands of hair, and a thread of the plurality of light guides may be formed, thereby increasing an area coming into contact with the scalp.
As is described above, a signal may be effectively extracted by exposing scalp and enabling a probe to come into close contact with the scalp using an apparatus for removing strands of hair from a near-infrared spectroscopy according to the present invention.
Further, a brain activation image may be efficiently measured by manufacturing a structure having a wedge shape, a toothbrush shape, and the like which are capable of enabling a probe form to reach up to scalp and by increasing an area coming into contact with the scalp.
