Patient interface for spectroscopy applications
First Claim
1. A method of locating a patient interface for a tissue measurement instrument on a patient, the patient interface defining a measurement side with one or more holes formed therein through which the tissue measurement instrument is configured to transmit and receive light to measure hemoglobin concentration of tissue, the patient interface having adhesive disposed on the measurement side, the method comprising the steps of:
- moving the patient interface around on the tissue in a particular region of the body while measuring hemoglobin concentration until a desired threshold attribute reading of hemoglobin concentration is achieved on the tissue measurement instrument; and
upon finding a location where the desired threshold attribute reading is achieved, affixing the patient interface to the patient at the location by adhering the adhesive on the measurement side to the patient.

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.

8. A method of locating a patient interface for a tissue measurement instrument on a patient, the patient interface having a measurement side with one or more holes formed therein, the measurement side having an adhesive thereon comprising first and second amounts of adhesive, the patient interface further having first and second liners covering the first and second amounts of adhesive respectively, the first liner having a first adhesive facing region attached to the first amount of adhesive, a first hinge region, and a first patient facing region connected to the first adhesive facing region through the first hinge region, the second liner having a second adhesive facing region attached to the second amount of adhesive, a second hinge region, and a second patient facing region connected to the second adhesive facing region through the second hinge region, the first and the second liners forming a separation therebetween, the method 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 attribute reading is achieved on the tissue measurement instrument is found; upon finding the location where a desired threshold attribute reading is achieved, firmly holding the patient interface to the patient at the location such that the first patient facing region and the second patient facing region contact the patient; pulling on the first patient facing region in a direction substantially normal to the separation to remove the first liner from the patient interface while holding the patient interface in place at the location so that the first amount of adhesive on the measurement side of the patient interface is exposed for attachment to the patient; holding the first amount of exposed adhesive against the patient; pulling on the second patient facing region in a direction substantially normal to the separation to remove the second liner from the patient interface so that the second amount of adhesive is exposed for attachment to the patient; and holding the second amount of exposed adhesive against the patient. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of locating a patient interface for a tissue measurement instrument on a patient, the patient interface having a measurement side with one or more holes formed therein, the tissue measurement instrument configured to measure hemoglobin concentration of tissue, the patient interface having adhesive disposed on the measurement side, the method comprising the steps of:
-
moving the patient interface around on the tissue along the adductor pollicis muscle while measuring hemoglobin concentration of the adductor pollicis muscle and determining a local maximum of hemoglobin concentration; and upon finding the location along the adductor pollicis muscle with the local maximum of hemoglobin concentration, affixing the patient interface to the patient at the location by adhering the adhesive on the measurement side to the patient. - View Dependent Claims (16, 17, 18, 19, 20, 21)
