PORTABLE ST02 SPECTROMETER
First Claim
1. A patient interface for a tissue measurement instrument, the patient interface comprising:
- a spring clip including a first arm member and a second arm member, the first and second arm members configured to provide a clamping force on a measurement site of a patient;
a plurality of radiation ports disposed in one or both of the first and second arm members, the radiation ports configured for light transmission therethrough;
a spring configured to bias the first and second arm members together; and
a means for optically connecting the patient interface to the tissue measurement instrument.

Abstract
Devices, systems, and methods for measuring tissue oxygen saturation (StO2) within the body are disclosed. A patient interface for use with a tissue measurement instrument can include a spring clip having a first arm and a second arm, a spring configured to bias the first and second arms together, and a means for optically connecting the patient interface to the tissue measurement instrument. The patient interface can be used in conjunction with an optical sourcing and receiving unit of a monitor for measuring tissue oxygen saturation at a measurement site on the patient. A testing interface on an external portion of the instrument housing and a testing module can be used to perform tests on the instrument.
