Magnetic Reusable Sensor
First Claim
1. A magnetic reusable sensor is configured to attach to a tissue site so as to illuminate the tissue site with optical radiation and detect the optical radiation after attenuation by pulsatile blood flow within the tissue site, the sensor is configured to communicate with a monitor so as to calculate a physiological parameter corresponding to constituents of the pulsatile blood flow determined by the detected optical radiation, the sensor comprising:
- a reusable portion having at least one optical element;
a disposable portion for removably securing the at least one optical element to a tissue site; and
at least one magnet disposed on at least one of the reusable portion and the disposable portion so as to releasably join the reusable portion to the disposable portion.

Abstract
A magnetic reusable sensor is configured to attach to a tissue site so as to illuminate the tissue site with optical radiation and detect the optical radiation after attenuation by pulsatile blood flow within the tissue site. The sensor is configured to communicate with a monitor so as to calculate a physiological parameter corresponding to constituents of the pulsatile blood flow determined by the detected optical radiation. The sensor has a reusable emitter and a detector. A disposable wrap removably secures the emitter and the detector to a tissue site via magnetically enhanced receptacles fixedly mounted on the wrap and magnetically enhanced carriers housing the emitter and the detector.

8. A magnetic reusable sensor comprising:
-
a fixed sensor portion having a plurality of emitters and a detector; a removable sensor portion magnetically attachable to and detachable from the fixed sensor portion; and the removable sensor portion having pads that receive a tissue site and position the tissue site with respect to the emitters and the detector so as to allow a sensor processor in communication with the emitters and the detector to activate the emitters and receive a corresponding signal from the detector indicative of a physiological characteristic of the tissue site. - View Dependent Claims (9, 10, 11, 12, 13, 14)
