Abstract: A cartridge can comprise a first elastomeric membrane and a second elastomeric membrane, and portions of the elastomeric membranes which are sealed to each other can circumscribe unsealed portions of the membranes. In a resting state, the unsealed portion of the first elastomeric membrane abuts or is proximate to the unsealed portion of the second elastomeric membrane. One or more reagents can be injected between the unsealed portions of the first and second elastomeric membranes to push the unsealed portions apart from each other in this region of the membranes. The unsealed portions can be sequentially pushed apart in downstream regions to form a channel between the elastomeric membranes. Positively displaced fluid pushes the unsealed membrane portions apart to a volume that conforms to the volume of the fluid to minimize or prevent dead volume in the channel and thus minimize or prevent air bubbles in the fluid.

Abstract: The invention envisions a multi-purpose expandable-collapsible frame apparatus that may be used as a bed frame. The apparatus utilizes a telescoping central support apparatus designed such that when a force is applied to the central support apparatus a plurality of floating arm assemblies expand outwardly from the central support apparatus. Furthermore, support straps and a covering member add stability and utility to the frame apparatus.
