 3, the strip module 200 is coupled to the mobile phone 300. When the strip module 200 is coupled to the portable terminal 300, the dye pad 210 is connected to the camera 320 of the portable terminal 300 And can be photographed by the camera 320 of the portable terminal 300. [

The transparent strip 220 reflects the light generated from the light source 310 of the portable terminal 300 so that the camera 320 of the portable terminal 300 can photograph an area where the dye pad 210 is positioned, 210).

In particular, the transparent strip 220 may be formed of a transparent material having a refractive index of 1 or more, but this is merely an example, and a light having a refractive index of less than 1 may be extracted to reflect the light reflected through the translucent material have.

In addition, the transparent strip 220 may be formed of one or more materials selected from the group consisting of polyethylene terephthalate (PET), polycarbonate, polyvinyl chloride (PVC), poly methyl methacrylate (PMMA), polytetrafluoroethylene (PTFE), polystyrene ), polyacrylates, polyacrylamides, polyamines, polyglycols, hydrogels, hydrophobic polymers, flexible polymers and acrylics. In addition, the transparent strip 220 may be in the form of a quadrilateral column, but this is merely an example, and may be implemented as a cylindrical column or a polygonal column.

In addition, the transparent strip 220 may be a colorless transparent material, but it is merely an example and may be a transparent material with a color (e.g., red, etc.).

Specifically, the transparent strip 220 is positioned on a specific surface (for example, the lower surface or the upper surface) of the transparent strip 220 in order for the camera 320 of the portable terminal 300 to photograph the dye pad 210 The light emitted from the light source 310 of the portable terminal 300 may be totally or partially reflected and transmitted to a region where the dye pad 210 is located. At this time, the camera 320 and the light source 310 may be located on the same plane with respect to the transparent strip.

The camera 320 of the portable terminal 300 can photograph an area where the dye pad 210 is located using the light transmitted through the transparent strip 220. At this time, the light source 310 may be positioned below the transparent strip 220, and may be positioned in the perpendicular direction, the equilibrium direction, and the diagonal direction.

At this time, the light source 310 of the portable terminal 300 is an LED, and the light emitted from the light source 310 may be white light or daylight color light. The light source 310 of the portable terminal 300 may be a fluorescent lamp or an incandescent lamp, and the light emitted from the light source 310 may be a red light, a green light, a blue light, or the like. In addition, the light generated from the light source 310 may be visible light range (400 to 700 nm), but it may be an ultraviolet ray (10 to 400 nm), an infrared ray (700 to 1 mm), a NIR (3 to 8 μm), LWIR (8 to 15 μm), FIR (15 to 1000 μm), and the like. That is, the portable terminal 300 can photograph the dye pad 210 through which the sample (for example, blood) is injected, using the light source 310 for image capturing through the transparent strip 220. Then, the portable terminal 300 can analyze the photographed image and measure information (for example, blood sugar) about the sample.

Accordingly, the user can acquire information of various samples using the portable terminal 300 such as a smart phone without using a separate blood glucose measurement device.

Hereinafter, embodiments of the present invention will be described in which a sample is blood, and blood glucose information is acquired through blood.

FIGS. 3 to 4B are views for explaining the strip module 200 for measuring blood glucose, which is coupled to the portable terminal 300, according to an embodiment of the present invention.

First, the strip module 200 can be coupled with the portable terminal 300 through the guide module or the housing part. Specifically, the guide module may be detachably attached to the cover case of the portable terminal 300 or the portable terminal 300, and the strip module 220 may be inserted into the guide module and coupled with the portable terminal 300. Or the strip module 220 may be combined with the cover case of the portable terminal 300 or the portable terminal 300 through the coupling part of the housing part.

3A, the first region of the transparent strip 220 is positioned on the light source 310 and the transparent region of the transparent strip 220, The second area where the pad is located may be located on the camera 320. [ In general, the light source 310 and the camera 320 are disposed on a straight line on the back surface of the portable terminal 300, so that the transparent strip 220 is a straight line image on which the light source 310 and the camera 320 are positioned. The portable terminal 300 can be connected to the portable terminal 300 in parallel.

On the other hand, since the distance between the camera 320 and the dye pad 210 is several millimeters, the distance is very close and it may be difficult to focus. Thus, according to one embodiment of the present invention, a Fresnel lens 230 may be positioned between the camera 320 and the dye pad 210. [ That is, the Fresnel lens 230 reduces the focal distance of the camera 320, thereby enabling a clearer image to be captured. At this time, the Fresnel lens 230 can be mounted on the housing part of the strip module 200. In addition, the strip module 200 can adjust the focal distance by using a variety of optical focusing devices such as a convex lens or a concave lens in addition to the Fresnel lens 230.

In addition, the dye pad 210 may be disposed on one area of the transparent strip 220, as shown in FIG. 4A. Specifically, as shown in FIG. 4B, a color dye ink pad 210 may be formed on the transparent strip 220 in a colorimetric manner. A mesh 240 may be formed on the dye pad 210 to allow the blood sample to pass through the double-sided tape 250. The mesh 240 and the dye pad 210 may be fixed to the transparent strip 220 by the fixing tape 260.

At this time, the transparent strip 220 may be formed of a transparent polymer material that allows total internal reflection to occur, as shown in FIG. 3A. For example, the transparent strip 220 may be implemented with a transparent polymer material having a refractive index greater than 1 (e.g., polyethylene (PET) having a refractive index of 1.6, PC (Polycarbonate), acrylic having a refractive index of 1.58, . It should be noted that the transparent strip 220 may be realized not only as a transparent material but also as a translucent material capable of transmitting light. 6 (a), the transparent strip 220 may be embodied as a bar without a hole, but this is merely an example, and the transparent strip 220 may be formed of a dye pad 210, 6f (b)) or a quadrangle (Fig. 6f (c)) around the area in which the light is scattered, the light totally reflected from the blood sample is irradiated to the blood sample in the form of a ring light, So that it can be observed. If the color of the transparent strip 220 is red, the transparent strip 220 may serve as a filter that passes only the light source in the red wavelength band region. Particularly, when the blood is injected into the bloodstream and the health information or the disease information is measured, the red filter, which is a red component contained in the blood, may be additionally required as a red filter. Therefore, Allowing more accurate measurements without the need for additional equipment.

Therefore, when the blood glucose measurement start command is input to the portable terminal 300, the light source 310 of the portable terminal 300 generates white light, and the generated white light is totally reflected or diffused through the transparent strip 220, And transmits white light to the area where it is located. The camera 320 of the portable terminal 300 can take blood of the dye pad into which the blood sample is injected using the reflected white light and analyze the captured image to measure blood sugar.

3 to 4B, the strip module 200 may further include a blood removing pad for removing blood cells of a blood sample. That is, the blood cell removal pad for removing red blood cells may be disposed on the dye pad 210 in order for the portable terminal 300 to measure blood glucose more accurately. In particular, according to one embodiment of the present invention, the electronic device 300 analyzes the mode value of the red color of blood to measure blood sugar. At this time, since red blood cells have red color, it affects the mode value of red color of blood, which may interfere with accurate blood glucose measurement. Therefore, erythrocytes can be removed through the hemocyte removal pad to enable more accurate blood glucose measurement.

Hereinafter, various embodiments in which the strip module 200 is coupled to the cover case of the portable terminal 300 or the portable terminal 300 will be described with reference to FIGS. 5A to 8.
