Abstract:
A biosensor detects a medication applied to an upper epidermal layer of skin of a user. The biosensor obtains at periodic intervals a concentration level of the medication in the upper epidermal layer of skin and surrounding tissue of the user. The biosensor may also detect the concentration level of the medication in an arterial blood flow of the patient or obtain a concentration level of a substance in the arterial blood flow, wherein the concentration level of the substance correlates to a first concentration level of the medication. The biosensor may determine an absorption rate of the medication in the upper epidermal layer of skin and surrounding tissue and in an arterial blood flow of the patient from the detected concentration levels of the medication obtained at the periodic intervals.
Abstract:
A biosensor unit is coupled to a user device and may communicate with the user device over a short range wireless or wired interface. The biosensor unit includes an optical sensor used to obtain an oxygen saturation level, a heart rate and a respiration rate of a user. The biosensor unit may also obtain a blood pressure and a temperature of the user using one or more other sensors. The biosensor unit transmits the obtained biosensor data to the user device using the short range interface.
Abstract:
A biosensor includes an optical sensor circuit that emits light directed at skin tissue of a patient at a plurality of wavelengths. A first and second spectral response of light reflected from the tissue is obtained around a first wavelength in a UV range and a second wavelength in an IR range. A measurement of nitric oxide (NO) is then determined from the spectral responses. A risk of septic condition is obtained using the measurement of NO.

A biosensor includes a PPG circuit that emits light directed at living tissue at a plurality of wavelengths. A first and second spectral response of light reflected from the tissue is obtained around a first wavelength and a second wavelength. Using absorption coefficients for substances at the plurality of wavelengths, concentration levels of a plurality of substances such as Nitric Oxide may then be determined from the spectral responses.

Abstract:
An integrated drug delivery and biosensor (IDDB) system is implemented on a patch or arm band. The drug delivery system includes needles adapted to pierce the skin and direct injection of a predetermined dosage of medication through the needles into the epidermis of the skin of a patient. The integrated biosensor monitors absorption of the medication into the epidermis of the skin of the patient and may also monitor concentration of the medication or other relevant substances in arterial blood flow of the patient. The integrated biosensor may also monitor a patient's vitals in response to the medication. The integrated biosensor may then alter dosage or frequency of administration of dosages or even halt a dosage of medication in response to the patient's vitals or absorption of the medication.

Abstract:
A glucose biosensor includes a plurality of optical fibers configured for placement within the ear canal. A first optical fiber emits light into the ear canal. A plurality of other optical fibers capture and transmit the reflected light back to the glucose biosensor. A plurality of photodetectors are configured in the glucose biosensor to detect the reflected light from the plurality of optical fibers. The glucose biosensor processes the detected light from each photodetector to determine a glucose level measurement. In an embodiment, the glucose biosensor also includes a wireless interface to transmit the glucose level measurements to a glucose meter and/or a gateway.
Abstract:
A photoplethysmography (PPG) circuit obtains PPG signals at a plurality of wavelengths of light reflected from tissue of a user. A processing device generates parameters using the PPG signals to screen the user for an infection, such as sepsis, influenza and/or COVID-19. The processing device may also determine a severity level of the infection and a confidence level in the determination. The parameters may include a measurement of nitric oxide (NO) level, respiration rate, heart rate and/or oxygen saturation.
