NON-INVASIVELY MONITORING BLOOD PARAMETERS
First Claim
1. An apparatus for monitoring vital sign parameters in a biological entity, comprising:
- at least one light source;
at least one photodetector positioned to receive light transmitted through the biological entity from the light source, the at least one light source and at least one photodetector configured to be positioned proximate the biological entity in a manner that does not significantly impede blood flow through the biological entity;
a signal generated in response to the transmittance or reflectance of light through the biological entity, the signal corresponding to at least one characteristic of the generally unimpeded blood flow through the biological entity; and
a control system configured to analyze the signal to determine vital sign parameters of the biological entity.

Abstract
An apparatus for monitoring vital sign parameters in a biological entity is disclosed. In an embodiment, the apparatus includes at least one light source for transmitting light through the biological entity and at least one photodetector for receiving light transmitted through the biological entity. At least one light source and at least one photodetector are configured to be positioned proximate the biological entity in a manner that does not significantly impede blood flow through the biological entity. A signal is generated in response to the transmittance or reflectance of light through the biological entity. The signal corresponds to at least one characteristic of the generally unimpeded blood flow through the biological entity. The apparatus also includes a control system configured to analyze the signal to determine vital sign parameters in the biological entity. A method for monitoring vital sign parameters in a biological entity is also provided.
