Abstract

A fluid processing system is described having at least two chambers. Each of said chambers is separated in a first and a second part by a flexible membrane, the first part, in use, comprising essentially a gas and the second part, in use comprising essentially a non- gaseous fluid, an inlet and / or an outlet means. One or more channels are provided connecting said second parts of said at least two chambers, wherein at least one of said one or more channels includes a pressure sensitive one-way valve. Further, means for exerting pressure on said first part of at least one of said at least two chambers is provided to allow transfer of a sample liquid.

Description

technical field [0001] The present invention relates to the field of fluid handling in the biological and medical disciplines. In particular, the invention relates to the field of molecular diagnostics, especially in the detection of bacteria, blood processing and diagnostics or applications in heart transplantation. Background technique [0002] In medical applications, fluid handling is very important. An integrated system in which fluids can be processed in a closed box in several steps has the advantages of saving time, user friendliness and limiting human disturbance, however there is also a risk of cross-contamination. The system described in US5193990 allows flow control of the flow of fluid from the main chamber. The main chamber is divided by a diaphragm into two zones: a first zone into which fluid flows in and out and a second zone filled with gas. The first level of control is performed by monitoring the pressure change of the gas relative to the gas in a fixe...
