A battery-powered medical device comprising an outer housing having an opening formed therein, at least one power source housed within the outer housing, which is configured to at least partially enclose the power source so as to prevent contamination of the power source with biohazardous materials, and the power source being removable from the outer housing via the opening, a cover configured to cover the opening in the outer housing and to retain the power source within the outer housing, and an actuator provided within the outer housing that engages with a portion of the power source when the cover covers the opening, wherein the actuator is configured to physically remove the power source from the outer housing and the outer housing is configured to release the power source via the opening without requiring physical contact between the user and the power source.

Medical devices with battery removal

A battery-powered medical device comprising: an outer housing having an opening formed therein; a power source housed within the outer housing, the outer housing being configured to at least partially enclose the power source so as to prevent contamination of the power source with biohazardous materials, the power source being removable from the outer housing via the opening; and a cover configured to cover the opening in the outer housing and to retain the power source within the outer housing, wherein the cover is configured to be operated by a user to expose the opening in the outer housing, when the cover is operated to expose the opening, the outer housing is configured to release the power source via the opening without requiring physical contact between the user and the power source, and when the cover is operated to expose the opening, the outer housing is configured to provide a direct path for release of the power source via the opening, such path providing no contact with contaminated surfaces of the medical device.

The invention provides a fuel cell stack including a layer of encapsulating material disposed about the separator plate, MEA, and reactant manifold, wherein the reactant manifold is bounded at least in part by the encapsulating material. The fuel cell stack also includes a first opening through the plate body to the first face from the second face, and an open channel in the second face extending from the opening toward a periphery of the plate. The invention also provides a fuel cell stack having a first face including an opening for passage of a reactant therethrough, a first reactant flow field defined thereon, and a first raised surface formed thereon substantially surrounding the opening. The first raised surface is configured and adapted to mate with a second surface on a face of an adjacent plate to create a flow obstruction for encapsulating material.

Fuel cell stacks and methods

The present invention provides, among other things, membrane cassettes and stacks thereof which are suitable for a use in a variety of electrochemical applications. The invention further provides membrane cassettes which comprise one or more external manifolds which deliver reagents and/or coolant to one or more reactant or coolant flow fields of the membrane cassettes. In particular, the present invention describes the insert molding method, whereby the plenums of the external manifolds are created during the stack encapsulation step. The invention describes several methods for creating the manifold runner geometry via insert-molding, machining, or with separate components.
