Variable pressure reusable sensor
First Claim
1. A variable pressure reusable sensor comprising:
- a first jaw having a first hinge and an emitter;
an opposing second jaw having a second hinge and a detector;
a pin disposed through said first and second hinges so as to rotatably attach said first and second jaws;
said jaws adapted to attach to a tissue site so that said emitter transmits optical radiation into said tissue site and said detector receives said optical radiation after absorption by said tissue site;
a spring having a plurality of legs, said spring disposed around said pin and configured so that said legs apply force to said jaws; and
a tensioner disposed proximate at least one of said jaws and configured to variably position at least one of said legs so as to adjust pressure exerted by said jaws on said tissue site.

Abstract
A variable pressure reusable sensor has a first jaw having a first hinge and an emitter and an opposing second jaw having a second hinge and a detector. A pin is disposed through the first and second hinges so as to rotatably attach the first and second jaws. The jaws are adapted to attach to a tissue site so that the emitter transmits optical radiation into the tissue site and the detector receives optical radiation after absorption by the tissue site. A spring having a plurality of legs is disposed around the pin and configured so that the legs apply force to the jaws. A tensioner is disposed proximate at least one of the jaws and configured to variably position at least one of the legs so as to adjust pressure exerted by the jaws on the tissue site.

8. A variable pressure reusable sensor method comprising the steps of:
-
providing a sensor clip having an open position for inserting and removing a tissue site and a closed position for attaching said clip to said tissue site;
emitting optical radiation into said tissue site in said closed position;
receiving said optical radiation after absorption by said tissue site;
generating a physiological signal responsive to said absorption; and
urging said clip to said closed position with a variable force so as to adjust the pressure of said clip against said tissue site. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A variable pressure reusable sensor comprising:
-
a plurality of jaws adapted to attach to a tissue site, said jaws having an emitter that transmits optical radiation into said tissue site and a detector that receives optical radiation after absorption by said tissue site;
a selected spring configuration disposed proximate said jaws so as to apply force to said jaws; and
a spring set providing a range of tension characteristics, said selected spring configuration chosen from said spring set so as to provide a particular pressure profile on said tissue site. - View Dependent Claims (17, 18, 19, 20)
