Abstract:
An optical circuit detects PPG signals reflected from skin tissue at one or more different wavelengths. A processing circuit integrated in the biosensor or in communication with the biosensor processes the PPG signals to obtain a level of vasodilation or a period of vasodilation. The processing circuit may determine a circulation level using a phase offset between the PPG signals and/or a correlation value between the PPG signals.
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 health care band operably attaches a biosensor to a patient. The biosensor includes one or more sensors for collecting vitals of a patient and a wireless transmitter that is configured to communicate with an EMR network that stores and maintains an EMR of the patient. The biosensor stores a unique identification associated with the patient's EMR such that vitals measured by the biosensor may be transmitted with the patient's unique identification for storage in the patient's EMR. The sensors in the biosensor may include a thermometer, motion detector/accelerometer, pulse detector and oximeter, etc. In an embodiment, one of the sensors in the biosensor includes a photoplethysmography (PPG) based sensor that may be configured to continuously or periodically measure a patient's vitals, such as heart rate, pulse, blood oxygen levels, blood glucose or insulin levels, or other blood analytics in vitro.
