Abstract:
1. A fluid sample transport device with reduced dead volume for at least one of processing, controlling and detecting a fluid sample, comprising: a substrate including a cavity for holding the fluid sample, wherein an upper surface of said substrate comprises at least one processing, controlling and detecting element; at least one flexible membrane arranged on the upper surface of said substrate; at least one actuating element for actuating a movement of the at least one flexible membrane towards and away from the substrate to cause at least one of a fluid flow and a fluid stop the fluid flow of the fluid sample; and at least one cover plate arranged on at least one of an upper outer surface and a lower outer surface of the at least one flexible membrane; wherein the at least one cover plate comprises at least one through going opening for receiving the at least one actuating element, so that movement of the at least one actuating element causes at least one of a pump and a valve action of adjacent areas of the at least one flexible membrane to cause the fluid flow between the upper surface of said substrate and the lower outer surface of said at least one flexible membrane, and wherein at least one temporally formed channel to direct the fluid flow of the fluid sample the substrate is temporally formed by expansion of the at least one flexible membrane into a further through going opening of the at least one cover plate in response to the at least one actuating element pushing the at least one flexible membrane into the cavity for forcing the fluid sample out of the cavity to form the at least one temporally formed channel.
