Releasable liner for sensor device
First Claim
Patent Images
1. A sensor device comprising:
- an electrode vest having a plurality of electrodes;
a guide fixed to the electrode vest;
a retainer fixed to the electrode vest;
a protective liner comprising a continuous strip folded onto itself to form a first strip portion and a second strip portion, the first strip portion releasably attached to at least one of the plurality of electrodes, the first strip portion having a fixed end portion attached to the electrode vest and a second end portion engaged with the retainer, and the second strip portion includes a first end portion coupled to the second end portion of the first strip portion proximate the retainer and a second, free end portion that extends through the guide, the second strip portion having a second strip surface in contact with a skin surface of a patient when the sensor device is placed onto the patient,wherein a pulling force applied to the second, free end portion causes the first strip portion to separate from at least one of the plurality of electrodes,wherein the pulling force causes the continuous strip to disengage from the retainer, andwherein the second strip surface includes a low coefficient of friction to minimize abrasion of the skin surface when the pulling force is applied.

Abstract
A releasable liner for a sensor device having adhesive and conductive gel portions includes a flexible sheet having a free end and a fixed end, and a portion of the flexible sheet that is releasably attached to the sensor device, wherein the flexible sheet is folded upon itself so that the fixed end is generally adjacent the free end. Exerting a pulling force on the free end releases the liner in a controlled manner to uncover the adhesive and conductive gel portions of the sensor device.

3. A method for placing a sensor device in contact with a patient'"'"'s anatomy, the method comprising the steps of:
-
positioning the sensor device on the patient in a desired position, the sensor device having a plurality of electrodes, a guide, a retainer, and a continuous protective liner folded onto itself to form at least two strips wherein one strip is coupled to the plurality of electrodes and attached to the sensor device while the other strip is in contact with a skin surface of a patient; and applying a pulling force to a free end of the other strip to release the continuous protective liner from the retainer and separate the one strip from the plurality of electrodes, wherein applying the pulling force includes generating relative motion between the continuous protective liner and the patient'"'"'s anatomy, and wherein the other strip includes a low-friction, contact surface for preventing abrasion between the other strip and the patient'"'"'s anatomy during the relative motion. - View Dependent Claims (4, 5)
