Abstract
A monitoring system for monitoring the health status of a patient and transmitting to a remote receiver a signal, based on measured physiological parameters. A sensor is incorporated in a finger ring or other article of apparel so as to monitor skin temperature, blood flow, blood constituent concentration, or pulse rate of the patient. The data are encoded for wireless transmission by mapping a numerical value associated with each datum to a pulse emitted after a delay of a specified duration following a fiducial time. Multiple ring bands and sensor elements may be employed for deriving three-dimensional dynamic characteristics of arteries and tissue of the finger.
Claims16
A monitoring system for monitoring the health status of a patient, comprising:
- a. a finger ring to be worn by the patient, the finger ring comprising:
- i. at least one sensor for providing a signal based on at least one of skin temperature, blood flow, blood constituent concentration, and pulse rate of the patient;
- ii. a transmitter for converting the signal to a wave;
- and
- iii an accelerometer disposed within the finger ring for removing signal artifacts due to finger motion;
- b. at least one receiver for receiving the wave from the finger ring;
- and
- c. a controller for analyzing the wave and determining an abnormal health status.
A monitoring system for monitoring the health status of a patient, comprising:
- a. a monitor having a first and a second band to be worn by the patient on a single finger, the monitor comprising:
- i. at least one sensor disposed on the first band for providing a first signal based on at least one of skin temperature, blood flow, blood constituent concentration, and pulse rate of the patient;
- ii. at least one sensor disposed on the second band for providing a second signal based on at least one of skin temperature, blood flow, blood constituent concentration, and pulse rate of the patient;
- and
- b. a controller for analyzing the first and second signals and determining a physiological characteristic of the patient.
