Abstract
A patient interface and method of locating the patient interface for use particularly in spectroscopy applications. The patient interface includes a concave region and first and second convex regions. A wing extends from the concave region to help locate the patient interface properly. The convex regions provide additional adhesion support, particularly when used on the thenar eminence. The patient interface may be placed in a number of locations on a patient to determine an optimum location for measurement prior to affixing the interface to the patient.

17. A method of locating a patient interface for a tissue measurement instrument on a patient, the patient interface having a measurement side with a light transmission hole and a light receipt hole, the measurement side having an adhesive thereon, comprising the steps of:
-
moving the patient interface around on the tissue in a particular region of the body until a location where a desired threshold reading is achieved on the tissue measurement instrument is found;
upon finding the location where a desired threshold reading is achieved, firmly holding the patient interface to the patient;
partially removing the patient interface from the patient while holding it in place so that a first amount of adhesive on the measurement side of the patient interface may be readied for attachment to the patient;
placing the first amount of exposed adhesive on the patient;
partially removing the patient interface in a second direction so that a second amount of adhesive may be readied for attachment to the patient; and
placing the second amount of exposed adhesive on the patient. - View Dependent Claims (18)
