Non-adhesive oximeter sensor for sensitive skin
First Claim
1. A sensor comprising:
- a light emitting element;
a light detecting element;
a substrate configured to encircle a portion of a patient, the substrate adapted to support the light emitting element and the light detecting element between layers, the substrate comprising a non-adhesive polyvinyl chloride material having a patient-contacting surface, the substrate having a thickness of less than 0.1 inch and being adapted to releasably attach one portion of the substrate to another portion of the substrate for securement to the patient, wherein the substrate comprises at least two layers laminated together;
a cable coupled to the light emitting element and to the light detecting element; and
a strap coupled to the cable, the strap being configured to wrap around a portion of the patient'"'"'s body to secure the cable to the patient.

Abstract
The present invention provides non-adhesive oximeter sensors for patients with sensitive skin. Sensors of the present invention include a light emitting diode (LED) and a photodetector. The LED and the photodetector may be covered by a reflective mask and a faraday shield. Sensors of the present invention have a non-adhesive laminated layer. The non-adhesive layer contacts, but does not stick to, the patient'"'"'s skin. When the sensor is removed from the patient, the non-adhesive layer does not tear or irritate the patient'"'"'s skin. The non-adhesive layer preferably has a large static coefficient of friction. Sensors of the present invention can also have hook-and-loop layers. The sensor can be attached to the patient'"'"'s body by wrapping the sensor around the patient and engaging the hook layer to the loop layer.
