The present invention relates to an optical condensing unit and a medical diagnostic device including the same, and more particularly, an optical condensing unit for condensing a predetermined light emitted from a wide light source to a predetermined position, and a living body emitted from the organism using the same. The present invention relates to a health checker including an optical light collecting unit for diagnosing a health state of an organism by collecting and measuring biophotons of light and analyzing the measured results.

The organism spontaneously emits bio light in the visible region without external stimulation, and it is reported that the biophoton of the emitted bio light is closely related to the metabolism of the organism.

This study of biophotons began in the early 1920s when Russian scientist A. Gurwitsch discussed the issue of how tissues communicate and transform information about the size and shape of different organs. It is also hypothesized that release is due to internal biochemical reactions involving the oxidative metabolic process of the organism or due to the generation of free radicals and the activity of enzymes.

As such, the linkage between the biolight and the metabolism of the organism has not been accurately identified, but the emission of the biolight from the organism is closely related to the physiological or pathological state of the organism, and the change in the number of biophotons Experts in the life sciences think that it contains important information about changes in the health status of living things.

For this reason, in recent years, a lot of researches have been conducted for the development of a health diagnostic device for diagnosing changes in the health state of living organisms by changing the number of biophotons emitted from the living organisms. Photon Multiplier Tube (PMT) is mainly used. Here, the photomultiplier tube is a device that multiplies the number of biophotons of the bio-light emitted from the measurement site of the organism, and then measures this to generate an electrical signal for the number of biophotons.

However, the intensity of biolight emitted from living organisms is very weak. For example, the number of biophotons of bio-light from human palms, or soles of the feet is very small, ranging from 20 to 1000 / 0.01 seconds. Therefore, it is not easy to measure the biophotons of the bio-light only by the photomultiplier tube, and the reliability of the measured data is too low to diagnose the health state according to these changes.

Therefore, in order to measure the number of biophotons of the biolight through the photomultiplier, the amount of biolight incident into the photomultiplier should be increased. However, since the incident surface area of the photomultiplier tube into which the bio-light is incident is very small, about 10 cm in diameter, condensing light is collected for condensing the bio-light in order to measure the number of bio-photons of the bio-light emitted from a large area to be measured. Requires unit

In general, a lens is used to collect light emitted from a light source having a large area to a predetermined position. However, when using a lens, there are some problems as follows. First, since light has different refractive indices according to wavelengths, aberration correction is required to measure the number of photons according to wavelengths. Second, in order to collect light emitted from a large area light source, the lens itself becomes very thick and large, which makes aberration correction more difficult. Third, when several lenses are overlapped, the transmittance is remarkably dropped to about 70%, so that the intensity of light to be measured is reduced to lower the light collection efficiency.

Therefore, until now, the development of a health diagnostic device for diagnosing the health state of living organisms by measuring the number of biophotons of the biolight using a photomultiplier tube is insufficient. In order to develop this, biolight emitted from a large area to be measured is developed. There is a demand for development of an optical condensing unit having a high light collecting efficiency for condensing a light into a predetermined position in a photomultiplier tube having a narrow incident surface.

Accordingly, the present invention is to provide an optical condensing unit that uses a mirror to efficiently collect light emitted from a light source having a large area to a predetermined position.

In addition, the present invention is to provide a health diagnostic apparatus including a light condensing unit for the optical concentrating efficiency to increase the intensity of the bio-light to be measured.

The present invention is an optical condensing unit for condensing the light emitted from the light source to a predetermined position, the input unit is formed with an input port through which light is incident, and is formed to face the input port and has a diameter smaller than the diameter of the input port is incident through the input port And a side part surrounding the input part and the exit part, and a mirror for reflecting light to the exit part is formed on the inner side of the side part.

In the optical condensing unit according to the present invention, the inner surface of the side portion has a rotating parabolic structure in which a straight line connecting the center of the inlet and the center of the outlet is the central axis, the center of the outlet is the focus, and the lower end portion below the focus is cut off. It is desirable to have.

The parabola having the following equation is formed by rotating 180 degrees about the central axis, wherein the variable x is preferably -a≥x≥a.

On the other hand, the present invention for achieving the above object is a health diagnostic device comprising an optical condensing unit, the bio-light emitted from the measurement site of the organism is incident through a predetermined movement path, the number of bio-photons of the incident bio-light A photomultiplier tube (PMT) for multiplication to be detected as a predetermined signal; An optical condensing unit, disposed on a movement path between the portion to be measured and the photomultiplier tube, for condensing a living light to a predetermined position in the photomultiplier tube; And a data processing unit connected to the photomultiplier tube and analyzing a predetermined signal detected from the photomultiplier tube to process data about the health state of the organism, wherein the optical light collecting unit includes an input unit in which an input port through which the bio light is incident is formed. And an emitter having a diameter formed so as to be opposite to the inlet and having a diameter smaller than the diameter of the inlet, and having an outlet through which the biolight incident through the inlet is emitted to the outside; It characterized in that it comprises a side portion is formed a reflecting mirror.

It is preferable to have a parabolic structure.

The parabola having the following equation is formed by rotating 180 degrees about the central axis, wherein the variable x is preferably -a≥x≥a.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of an optical light collecting unit according to the present invention.

1A is a perspective view schematically showing an embodiment of an optical light collecting unit according to the present invention, and FIG. 1B is a perspective view showing an inner side surface of the optical light collecting unit shown in FIG. 1A.

Referring to FIG. 1A, the optical condensing unit 100 according to the present invention includes an input unit 101 disposed at an uppermost end, an emission unit 102 disposed opposite the input unit 101 at a lower end thereof, and a side part surrounding the input unit 101 ( 103).

That is, the inlet 101 is formed with an inlet 101a through which light emitted from a light source is incident at the center, and the emitter 102 has a diameter smaller than the diameter of the inlet 101a at the center thereof. An emission hole 102a through which light injected through the light is emitted is formed. In addition, the input part 101 and the discharge part 102 are surrounded by the side part 103 having a uniform thickness, and the light incident through the input hole 101a is prevented on the inner side surface 103a of the side part 103. A mirror is formed that reflects light to be emitted to the outside through the outlet 102a. Here, the mirror is not dependent on the wavelength of light and reflectance is more than 99%, so the light loss due to reflection is hardly generated. The method of manufacturing such a mirror can be formed by coating a material such as metal or glass on the inner surface 103a of the side portion, and if necessary, a metal film is coated on the surface or a multilayer film of a whole medium (electromagnetic medium). A reflectance can also be improved by vapor-depositing by a vacuum vapor deposition method.

In one embodiment of the optical condensing unit 100 according to the present invention having such a configuration, as shown in FIG. 1B, the inner side surface 103a of the side portion is the center 101b of the inlet 101a and the discharge port 102a. It has a rotating parabolic structure in which a straight line connecting the center 102b of the center is the central axis A, the center 102b of the discharge port 102a is the focus, and the lower end portion below the focus is cut off.

The rotating parabolic plane is a surface formed by rotating an arbitrary parabola about a central axis. When a mirror is formed on the rotating parabolic plane, light incident into the rotating parabolic plane is reflected to the mirror once and then passes through a focus. In this case, it is assumed that light incident into the rotating parabolic surface is incident in parallel with the central axis.

Accordingly, the optical condensing unit according to the embodiment of the present invention includes a side portion having the rotating parabolic structure cut at the lower end portion below the focal point as the inner surface 103a, and the mirror is formed on the inner surface 103a. The light incident through the inlet 101a is immediately reflected or emitted outside through the outlet 102a without being reflected or reflected only once. Thus, problems such as light intensity reduction due to multiple reflections do not occur.

Hereinafter, a method of forming a rotating parabolic structure, which is an inner surface structure of an optical light collecting unit according to an embodiment of the present invention having such a structure, will be described in more detail with reference to FIGS. 2A and 2B.

FIG. 2A is a graph schematically showing an example of a parabola for forming a rotating parabolic surface which is an inner side structure of the side portion shown in FIG. 1A, and FIG. 2B is a state in which light is incident into a rotating parabolic surface formed through the parabolic surface shown in FIG. 2A. A schematic cross-sectional view.

First, in the optical condensing unit 100 according to the embodiment of the present invention illustrated in FIG. 1A, the radius of the inlet (101a in FIG. 1A) is referred to as a, and the radius of the emission port (102a in FIG. 1A) is represented by b. Assume that the parabola forming the rotating parabolic surface of the inner surface (103 of Figure 1a) can be schematically shown in Figure 2a.

In this case, the variables x are -a≤x≤-b and b≤x≤a. The distance L between the inlet and outlet is

Has the form of.

Therefore, when the parabolic of this shape is rotated about the central axis, i.e., the y axis, as shown in FIG. 2B, the inner side surface 103a of the rotating parabolic shape in which the lower end 201 below the focal point 203 is cut off is formed. Here, since the reflected light 202 moves upward through the focal point 203 in the cut lower end portion 201, the side portion (FIG. 1A) of the optical condensing unit 100 of FIG. 1A according to the exemplary embodiment of the present invention. It is preferable that the inner side surface 103a of the edge 103 has a rotating parabolic structure in which the lower end portion 201 is cut.

For example, in the case of manufacturing an optical condensing unit having a radius a of 15 cm and a radius b of an emission port 5 cm,

의 수학식 형태로 나타나며, 이때 변수 x는 -15≤x≤-5 및 5≤x≤15이다. 이에, 상기와 같이 나타나는 포물선을 중심축을 중심으로 180도 회전시킴으로써 측면부의 내측면인 회전 포물면 구조를 얻을 수 있다. 여기서, 측면부의 높이가 되는 투입구와 방출구 사이의 거리는 10cm이다. Parabola is

Where x is -15≤x≤-5 and 5≤x≤15. Thus, by rotating the parabolic appearing as described above 180 degrees around the central axis it is possible to obtain a rotating parabolic structure that is the inner surface of the side portion. Here, the distance between the inlet and the outlet which becomes the height of the side part is 10 cm.

On the other hand, the optical condensing unit according to the present invention is not limited to the above embodiment, and many modifications are possible by those skilled in the art within the technical idea of the present invention. For example, since the shape of the inner side and the shape of the outer side are different, the thickness of the side portion may not be constant. This will be described below with reference to the drawings.

That is, the inner side surface 303a has a parabolic structure in which the lower end portion below the focus is cut like the optical condensing unit 100 of FIG. 1A, but the outer side surface 303b has a cylindrical shape. .

Thus, the optical condensing unit 300 according to another embodiment of the invention is not the thickness of the side portion 303 due to the different shape of the inner surface 303a and the outer surface 303b, the inner surface 303a By having the same structure as the inner surface (103a of FIG. 1A) of the optical condensing unit (100 of FIG. 1A) according to an embodiment of the present invention, the optical condensing unit (FIG. 1A) according to an embodiment of the present invention Has the same condensing efficiency as 100).
