Abstract
A cartridge for analyzing a biological sample, wherein the cartridge includes a fluid system having a plurality of channels and at least one valve, wherein the valve is covered on the outside by a cover, and wherein the valve is configured to be actuated by deforming a wall of the valve.
Claims20
A cartridge for testing a sample, the cartridge comprising:
- a main body;
- a continuous film bonded to a back of the main body;
- and
- a fluid system having a plurality of channels and a plurality of valves for controlling the flow of the sample through the fluid system,
- wherein each of the plurality of valves comprises a wall that has a flexible portion, a valve chamber, a first opening and a second opening, and wherein the valve is configured to be actuated and closed by deforming the flexible portion of the wall,
- wherein the valve chambers of said plurality of valves are formed by depressions in a rear side of the main body, and
- wherein the continuous film is common to said plurality of valves, the continuous film covering and fluidically closing all valve chambers and forming the respective walls of said plurality of valves.

A cartridge for testing a sample, the cartridge comprising:
- a main body;
- a continuous film bonded to a backside of the main body;
- and
- a fluid system having a plurality of channels and a plurality of valves for controlling the flow of the sample through the fluid system,
- wherein each of the plurality of valves comprises a wall that has a flexible portion, a valve chamber, a first opening and a second opening, and wherein the valve is configured to be actuated and closed by deforming the flexible portion of the wall,
- wherein the plurality of valves forms a group of normally open valves,
- wherein the cartridge comprises a further group of other valves of a different type which are initially closed, and
- wherein the continuous film forms walls of said both groups of valves.

A cartridge for testing a biological sample, the cartridge comprising:
- a main body having a front and a back;
- a fluid system having a plurality of channels and a plurality of valves for controlling the flow of the sample through the fluid system, wherein the channels are formed by depressions of a front side of the main body, and wherein the valves each comprise a valve chamber formed by depressions in the back of the main body, each valve chamber comprising a first and second opening connecting the valve chamber to the channels;
- a first continuous film bonded to the front side of the main body, which covers and fluidically closes the channels on the front side;
- a second continuous film bonded to a back side of the main body, which covers and fluidically closes the valve chambers on the back;
- and
- an elastically deformable cover bonded to the second continuous film and covering the second continuous film at a location remote from the respective valve chambers,
- wherein the second continuous film and the elastically deformable cover are common to the plurality of valves, the valves being configured to be individually actuated and closed by deforming the second continuous film and the elastically deformable cover at the location of the respective valve.
