1A to 1C are diagrams for explaining a basic principle of a portable diagnostic system according to an embodiment of the present invention.

In general, a biological sample diagnosis device diagnoses a biological sample by reacting blood or the like with a diagnostic kit and optically reading the reaction result. In this case, a conventional optical device had to be provided, and its volume was also quite large, so there was no disadvantage in terms of portability. On the other hand, it was economically expensive to purchase a diagnostic device separately from a user who needs to purchase a diagnostic strip regularly.

The present invention seeks to replace a separate optical device by using a device having a photographing function such as a general mobile terminal, for example, a smart phone.

1A illustrates a smartphone as a mobile terminal 100. In general, a smart phone has a photographing function, and thus has a photo detector (LED) such as a light emitting diode (LED) 110 and an image sensor for a flash function. Here, the distance between the LED 110 and the photodetector 120 may be set narrower or wider than a typical smartphone.

Figure 1b is taken with the mobile terminal 100, which is one component of the portable diagnostic system according to an embodiment of the present invention, the reaction strip of the diagnostic strip is set in the AF (auto focusing) mode at a distance of 10cm.

Figure 1c is taken with the mobile terminal 100, which is a component of a portable diagnostic system according to an embodiment of the present invention, the reaction result of the diagnostic strip, but in close contact with the LED 110 and the photo detector 120. In this case, the sharpness is lower than that of FIG. 1B, but it is possible to judge the three reaction results displayed in the 4 mm space.

The portable diagnostic system according to an exemplary embodiment of the present invention reads the response result of the diagnostic strip by using the mobile terminal 100 and displays the result on the display unit, that is, the LCD screen of the mobile terminal 100, thereby allowing the user to easily. It will provide convenience for diagnosing the state of health.

2 is a diagram illustrating a configuration of a portable diagnostic system according to an embodiment of the present invention. As shown in FIG. 2, the portable diagnostic system according to an exemplary embodiment of the present invention includes a mobile terminal 100, a mobile terminal case 200, and at least one diagnostic strip 300.

As mentioned above, the mobile terminal 100 refers to a device such as a smartphone, and has a photographing function in addition to a communication function. Accordingly, the mobile terminal 100 includes an LED 110 and a photo detector 120.

The mobile terminal case 200 is detachable from the mobile terminal 100. Meanwhile, the mobile terminal case 200 includes an optical pattern for reflecting the light generated from the LED 110 of the mobile terminal 100 through the diagnostic strip 300 to the photo detector 120. The optical pattern will be described in more detail below with reference to the drawings.

The diagnostic strip 300 refers to a general diagnostic kit for diagnosing biological samples such as blood, urine, serous fluid, and saliva.

3 is a diagram illustrating a configuration of a portable diagnostic system according to an embodiment of the present invention. 3 is a view illustrating a combination of the respective components illustrated in FIG. 2, that is, the mobile terminal 100, the mobile terminal case 200, and the at least one diagnostic strip 300.

The LED 110 and the photo detector 120 provided on the back of the mobile terminal 100 are coupled to match the optical pattern 210 provided in the mobile terminal case 200, and the diagnostic strip 300 is a mobile terminal case ( 200).

In FIG. 3, the light generated by the LED 110 is incident to the optical pattern 210 and passes through the diagnostic strip 300 through reflection, diffusion, and collection by the structure in the optical pattern 210. At this time, the light incident on the diagnostic strip 300 is collected by the optical pattern 210 and has a straightness, and the light having the straightness passes through the diagnostic regions 310-1, 310-2, 310-3 of the diagnostic strip 300. The detector 120 moves to the detector 120.

The photodetector 120 may receive light to read a response result of the diagnostic strip 300 as an image.

Although not shown in FIG. 3, the read image may be transmitted to the outside by wire or wirelessly through a communication unit (not shown), or may be displayed to a user using a display unit (not shown).

4A is a view illustrating in detail an optical pattern included in a mobile terminal case of a configuration of a portable diagnostic system according to an embodiment of the present invention, and FIG. 4B is a view illustrating in detail the flow of light through each structure of the optical pattern. .

As shown in FIG. 4A, the optical pattern 210 includes an optical path changing pattern 214, a scattering pattern 216, and a light collecting pattern 218. On the other hand, but may further include a concave pattern 212 for the straightness of the incident light it can be omitted.

The concave pattern 212 has a function of maintaining the straightness of the light scattered while being incident from the LED. That is, the light passing through the concave pattern 212 has a straightness, and since the light has a straightness, the light may be incident perpendicularly to the optical path changing pattern 214.

The optical path changing pattern 214 has a function of moving a path of incident light. That is, in order to reflect the light and scatter the light in the optical pattern 210, the incident light is refracted by the scattering pattern 216.

The scattering pattern 216 has a function of scattering light refracted by the optical path changing pattern 214 in the optical pattern 210.

Finally, the light collecting pattern 218 has a function of concentrating the light scattered by the scattering pattern 216 and incident the light into the diagnostic region of the diagnostic strip 300. Therefore, the light collecting pattern 218 may be manufactured in a zigzag shape.

All the components in the optical pattern 210 are composed of a transparent body, it is preferable that the configuration is integral.

The path of the light traveling through the above-described optical pattern 210 is illustrated in FIG. 4B.

As shown in FIG. 4B, the light generated and incident on the LED 110 has a scattering property because the surface of the LED 110 has a spherical shape. However, the concave pattern 212 will induce the straightness of the scattered light. Therefore, it is desirable to have a structure similar to a concave lens. However, the structure of the concave pattern 212 may be omitted if a light emitting unit capable of linearity of light is used.

The light travels straight to the optical path changing pattern 214, where the refracted light strikes the scattering pattern 216 and spreads within the optical pattern 210. At this time, the zigzag condensing pattern 218 collects light into each of the diagnostic areas 310-1, 310-2 and 310-3 of the diagnostic strip 300 to enable the photodetector 120 to obtain a clear image.

As such, the mobile terminal 100 may extract the response result of the diagnostic strip 300 as an image by an optical method, and the extracted image may be displayed to the user through a display unit (not shown). In addition, in the case of patients requiring regular check-ups, the results can be automatically sent to the hospital to enable the doctor to observe continuously.

5 is a view showing another embodiment of a portable diagnostic system according to an embodiment of the present invention. As illustrated in FIG. 5, the portable diagnostic system according to the exemplary embodiment may detach the plurality of diagnostic strips 300, 300-1, and 300-2. More specifically, the mobile terminal case 200 is recessed to store extra diagnostic strips 300-1 and 300-2. In the case of patients requiring continuous diagnosis, the diagnostic strips are used several times a day, so having such a configuration may provide convenience of not having to store the diagnostic strips separately.

In the foregoing description, each component and / or function described in various embodiments may be implemented in combination with each other, and those skilled in the art may recognize the present invention described in the claims below. It will be understood that various modifications and variations can be made in the present invention without departing from the spirit and scope.
