The present invention relates to a totally non-invasive and intelligent telemetry apparatus for monitoring continuous blood sugar levels, blood pressure data, psychological stress and other physiological parameters. It is, in particular, related to clinical monitors, health management gadgets and wearable medical devices involving reflective optical sensing design.
Modern lifestyle and food habits have huge impact on our physiological and psychological health. In this fast-paced society, it has become a necessity to track and manage our health and activities. In fact, globally 1 in 11 of us are suffering from diabetic condition and 21% of people in the US are standing on the diabetic border. In the coming quarter century, this count is expected to raise by more than 200 million and the prevalence is expected to raise by over 25%. The current technology either offers painful periodic invasive monitoring solution or disposable microneedles based monitoring solution. The current continuous glucose tracking devices also fails to monitor blood sugar levels in prediabetic range and neither acts as a management or prevention solution. Attempts have been made in the past by inventors and academic scholars to create a non-invasive technology, but their hardware and processing architecture proposals ignores underlying scientific principles of reflective sensing and real-time processing techniques.
The invention is hence directed towards a hardware design and real-time processing system that can intelligently overcome the barriers using boundary angle conditions and other signal altering factors like dispersion effects. The disclosure describes a reflective sensing based portable continuous blood sugar monitoring apparatus integrated with real-time diet recommendation and lifestyle management system, which can work for both prediabetic and diabetic population. The device also includes other health guidance components like blood pressure fluctuation tracking system, hypertension management system, sleep monitoring system and emergency life-support system.

The Near-Infrared (Near-IR) spectrometer comprises of a set of Near-Infrared LEDs and optical lens tilted at boundary angle θB. A distance of wavelength number (kλ) is kept between the light sources for attaining constructive interference. The tilt of the signal probe system assures that the Near-IR response is reflected from the bone boundary, which would not otherwise occur in normal direction. The optical lens focuses and constructively interferes Near-IR radiation on the sensing spot. The reflected optical response is captured and focused by an optical lens at the photodetector-end. The reflected response is recorded by the Near-IR photodetector.
Second Aspect

The green spectrometer comprises of a green LED and optical signal probe tilted at a critical angle (θc), and photodetection system of optical lens and green photodetector. The optical lens and green photodetector are placed at an optimal response receiving spot so that the internal reflection noise can be avoided. The light emitted by tilted green LED is reflected off the skin boundary and the reflected response is captured by the optical lens and green photodetector set.
Third Aspect
The third aspect of the invention shows a red indicator spectrometer. A set of two red photodetectors are placed on the either side of the red LED with optical lens at proximity and distant positions. The signal difference between the proximity photodetectors and distant photodetectors are taken to analyse the red signal dispersion values. The dispersion values are analysed through the internal circuitry of the telemetry apparatus.
Fourth Aspect

The dispersion values are analysed through the internal circuitry of the telemetry apparatus.
Fifth Aspect
In the fifth aspect of the invention, a dual side sensing Near-Infrared spectrometer is presented. A primary lens is used to focus the Near-IR response from the set of Near-IR LEDs arranged at distance of wavelength number (kλ). The Near-IR response is focused at an angle by the primary optical lens on the tilted beam splitter. The beam splitter refracts the radiation on one side and reflects the radiation on the other side. The light refracted by the beam splitter is focused and concentrated by a secondary optical lens tilted at a boundary angle θG. The light reflected by the beam splitter is further reflected and focused by a mirror to compensate the phase change. The mirror inverts the phase and focuses the light on the secondary lens on the other side tilted at the boundary angle θG. The light reflected from the bone boundary on the either side and the reflected response is captured by the corresponding optical lens on the photodetector end. The optical lens in turn focuses the light on the respective photodetectors. A set of mirrors, at optimal orientations and positions, can be utilized in the refracted space for equalizing the wave pathlength difference between the light in the refracted and reflected space.

One response line is utilized to analyse the total Infrared-red response and the other circuit line is utilized to obtain dispersion signal. An Instrumental Amplifier is attached to the proximity and distant photodetectors response output line for extracting the real-time dispersion information. The analysed dispersion signal is passed through a power notch to remove the power line noise. The analysed dispersion signal passes through an ADC to the microprocessor. The distant photodetector signal and proximity photodetector signal are aggregated using resistors and Transimpedance (TIA) amplifier. The response signals of Near-infrared light, green light and red-IR light are processed using the photodetector frontend circuit line of TIA amplifier, power notch, ADC and noise cancellation IC. The processed output response is then sent to the microprocessor. A main micro-switch set is attached between the photodetector frontend and response line of different light spectrum, which shifts the output response to respective photodetector circuit based on the input signals. The micro-switch set reduces the overall component use and power consumption. An additional switch set can be utilized to reduce the count of the power notch and Noise cancellation IC.
