Abstract

A paddle for use with a defibrillator, the paddle being formed of an applicator attached to a pad portion. The applicator includes a flexible plate, a handle attached to a top of the flexible plate, and an applicator connector disposed on a bottom of the flexible plate. The pad portion is electrically connected to the applicator, and includes a flexible backing that is shaped by the flexible plate, a pad portion connector disposed on the flexible backing to form a connection to the applicator connector, a lid attached to the flexible backing, and an adhesive conductive medium attached to a bottom of the flexible backing and removably encased by the lid. An electrical contact is disposed on the lid and is electrically connected to the pad portion and is exposed while the conductive medium is removably encased by the lid.

Claim

What is claimed is: 1. A paddle for use with a defibrillator, comprising: an applicator; a pad portion adapted to be electrically connected to said applicator and having a conductive medium removably encased by a lid; and an electrical contact electrically connected to at least one of said applicator and said pad portion, said electrical contact being exposed while the conductive medium is encased in said pad portion. 2. The paddle of claim 1, wherein said applicator has a plate that shapes said pad portion to a curvature of a patient. 3. The paddle of claim 2, wherein the plate has a portion that curves to the curvature of the patient. 4. The paddle of claim 2, wherein the plate is flexible. 5. The paddle of claim 1, wherein said pad portion further comprises a backing to which the conductive medium is attached, and said electrical contact is attached to the lid. 6. The paddle of claim 5, wherein said applicator further comprises a plate to which the backing is attached, the plate to shape the backing and the conductive medium to a curvature of a patient. 7.

Abstract

A heat spreader comprising a sheet of transparent diamond with an aperture therein that accommodates a solid-immersion lens (SIL). The heat spreader may be mounted within a clamp which allows the heat spreader to move freely across the Device Under Test (DUT) whilst maintaining a very high degree of planarity and contact between the diamond and the silicon substrate of the DUT. The DUT is secured to its electrical interface with a low profile clamp, the DUT may be held within the clamp by a mechanism that applies a pressure to the sides of the DUT package.

International Classification

E05C 9/02, E05C 9/18

Abstract

A latching device is mountable to a door. The device includes a rod and a pair of latches spaced apart along the rod. The rod is slidably movable relative to a channel between a first position and a second position, with the rod biased into the first position. Upon slidable movement of the rod, both the first and second latches generally move in unison to permit a releasable engagement of the first and second latches relative to two spaced apart protrusion of a frame to releasably secure the door relative to the frame. At least one of the first and second latches is slidably movable relative to the rod between a first position and a second position closer to the other respective latch.

International Classification

A61B 5/024, A61B 5/00

Abstract

An optical pulse-rate sensor includes a fixture, a light emitter, a light sensor, and a light stop. The fixture has a rim configured to contact a skin surface and enclose an area of the surface. The light emitter and light sensor are each coupled to the fixture and positioned opposite the area. The light stop is coupled to the fixture and positioned between the light emitter and the light sensor to shield the light sensor from direct illumination by the light source.

Abstract

A cardio-pulmonary compression device includes a motor () having a rotating portion, and a ball nut () mounted on the rotating portion and configured to rotate with the rotating portion. A ball screw () is received in the ball nut such that rotation on the ball nut advances and/or retracts the ball screw in accordance with a direction of the motor. A pad assembly () is coupled to an end portion of the ball screw such that longitudinal motion of the ball screw imparts a compression cycle to a patient.
