However, the conventional techniques have the following problems.
For people who have problems with blood sugar, blood sugar levels need to be measured regularly at regular times every day, and often have to be taken on the go at the time of measurement, so the blood sugar measuring device is small and transportable. Good things are required. However, the conventional infrared blood glucose level measuring device is large in size because it is made by collecting optical components, and the transportability is not good. In addition, there is an inconvenience of having to connect to an external device such as a mobile phone in order to perform data analysis even when transporting. In addition, there are cases where people are concerned about the eye while taking measurements on the go, and psychological resistance is also great. Furthermore, it becomes anxious whether it can measure correctly. For this reason, a regular blood glucose level measurement is difficult to perform, and there is a medical problem.

  Therefore, the present invention has been made to solve such problems, and can measure blood sugar levels, has good transportability, has a low psychological burden at the time of measurement, and is easy to measure. An object is to provide a small cellular phone with a built-in biosensor.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is an external view of a biosensor built-in mobile phone according to Embodiment 1 of the present invention. The biosensor built-in mobile phone 50 includes a speaker 22, a microphone 23, an operation unit 25, a display unit 26, and a labial mid-infrared sensor module 30.

  FIG. 2 is a cross-sectional view of the labial mid-infrared sensor module 30 that is a non-invasive sensor in the biosensor built-in mobile phone according to the first embodiment of the present invention. In the labial mid-infrared sensor module 30, mid-infrared light having a wavelength of 9.6 μm emitted from the quantum cascade laser 1 is reflected by the reflecting surface 7 and enters the ZnSe optical element 21. This mid-infrared light travels through the ZnSe optical element 21 while repeating total reflection. Further, the user's lips 39 are in contact with the ZnSe optical element 21. When the mid-infrared laser beam 31 is totally reflected by the ZnSe optical element 21, it oozes out as an evanescent wave 32 near the interface between the ZnSe optical element 21 and the lips 39.

  The evanescent wave is light that oozes out from the interface when the light is totally reflected at the interface having a different refractive index. The intensity of the evanescent wave depends on the distance from the interface and attenuates exponentially. Evanescent waves are special light that exists only in the vicinity of the interface. By using this light, other methods cannot obtain or obtain various phenomena such as structures and reactions at the surface / interface of a substance. It is difficult to obtain information. Here, it is used to measure the glucose level in the lips 39. Since the evanescent wave 32 resonates with glucose in the lips 39, the glucose concentration can be detected by measuring the change in energy (light quantity).

  The mid-infrared laser beam 31 resonated with glucose in the lips 39 finally enters the light receiving element 2. Incident light is signal-processed by the signal processing integrated circuit 3 on the Si substrate 4. The Si substrate 4 is disposed on the silver paste 6 on the copper heat sink 18 and is connected to the lead electrode 10 via the electrode 8 and the gold wire 9. The labial mid-infrared sensor module 30 is covered with the resin package 5 except for the ZnSe optical element 21.

  FIG. 3 is a block diagram for explaining a voice guidance function in the cellular phone with a built-in biosensor according to Embodiment 1 of the present invention. The labial mid-infrared sensor module 30 receives a command from the CPU 28, measures the glucose value, and outputs the measurement data to the signal processing IC 29. The signal processing IC 29 processes the measurement data from the labial mid-infrared sensor module 30 and outputs control data corresponding to the measurement data to the voice synthesis IC 27. The voice synthesis IC 27 receives the control data input from the signal processing IC 29, generates voice data corresponding to the control data, outputs the voice data to the speaker 22, and transmits the voice data to the user.

  FIG. 4 is a flowchart showing an operation procedure of the mobile phone with a built-in biosensor according to Embodiment 1 of the present invention. The mobile phone with built-in biosensor determines whether the current time is the measurement time based on the built-in timer and the preset measurement time (S1), and if it is not the measurement time (NO in S1), the state is determined. If the measurement time is reached (YES in S1), the user knows that the measurement time has come (for example, “the blood glucose measurement time has come”), display, vibration, etc. ( S2). This eliminates forgetting to measure. Next, it is determined whether or not the user inputs measurement start (S3). The input form may be voice (for example, “measure”) or an operation button. If there is no input (NO in S3), the state is continued, but if there is an input (YES in S3), a voice indicating that measurement is to be started (for example, “Since the measurement starts from now on, touch the lips to the sensor Please ") or display to the user (S4). Subsequently, the measurement operation is performed (S5), the measurement status (for example, “It is measuring correctly”), the advice (for example, “Please apply your lips to the sensor a little more”), the remaining measurement time (for example, “1 more The measurement is completed in minutes ") or the like is transmitted to the user by voice or display (S6). As a result, even one user can correctly perform the measurement operation, and can effectively use the waiting time. If the measurement is not completed (NO in S7), the measurement operation is continued (S5), but if completed (YES in S7), a voice indicating that the measurement is complete (for example, “Measurement is completed”) And display it to the user (S8). Subsequently, the measurement result is calculated and analyzed (S9), and the calculation result, advice, etc. are communicated to the user by voice (for example, “the blood sugar level is normal. Let's continue this tone”) or display (S10). . As a result, the user can immediately grasp his / her current health condition, and can have a guideline for future living attitudes.

  In addition, in order to memorize | store a measurement result for a long term or to analyze in detail, you may set so that it may transmit to a personal computer automatically, for example wirelessly. Of course, the measurement procedure may be communicated to the user by sound or display at the start of measurement, or a response method or the like may be communicated when a sensor abnormality occurs during measurement.

  As described above, according to the mobile phone with a built-in biosensor in the embodiment of the present invention, it is possible to measure a blood glucose level, have good transportability, have a small psychological burden at the time of measurement, and can be easily measured. A mobile phone with a built-in biosensor can be realized.

The ultraviolet LED irradiation unit 40 includes an ultraviolet LED 42 located at the center, and a scattering resin 41 arranged so that multiple triangular projections surround the ultraviolet LED 42.

With this configuration, the ultraviolet light emitted from the ultraviolet LED 42 is sterilized by irradiating the labial mid-infrared sensor module 30 facing the device with the apparatus closed, and the reflected light from the facing portion is scattered by the scattering resin 41. The operation unit 25, the display unit 26, the speaker 22, and the microphone 23 are also sterilized by scattering. Note that the software is configured so that the irradiation time of the ultraviolet light is completed in, for example, 1 minute in consideration of excessive consumption of the rechargeable battery. In addition, by using a switch (not shown) that is de-energized when the device is not closed, the UV LED 42 is interlocked so that it does not emit light, so that UV light does not enter the user's eyes. I do.
As described above, according to the mobile phone with a built-in biosensor in the embodiment of the present invention, a sanitary mobile phone with a built-in biosensor can be realized.

  Of course, other than the ultraviolet LED described here may be used for sterilization. Further, the sterilizing effect may be further improved by forming titanium oxide in the operation portion of the apparatus. When titanium dioxide is exposed to sunlight or ultraviolet light from fluorescent lamps, it oxidizes hydroxide ions through oxidation / reduction reactions, and generates active oxygen such as OH radicals that have a stronger oxidizing power than hydrogen peroxide (oxyfur) chlorine and ozone. appear. This is because this active oxygen decomposes and removes the molecular bonds of organic substances such as exhaust gas NO / SO, which is a harmful substance, and formaldehyde that causes sick house syndrome, and acetaldehyde / ammonia, which is a component of tobacco odor.
