Cartridge for automated medical diagnostics
First Claim
1. A cartridge for the detection of the presence, absence and/or amount of a target nucleotide sequence in a sample comprising one or more nucleic acid sequences, the cartridge comprising:
- a first component for processing a fluid having a sample, said first component including;
one or more processing chambers,a first fluid opening for fluid access to at least one of said processing chambers of the first component, anda first sealing surface associated with the first fluid opening;
a second component connectable to the first component for processing the fluid, said second component including;
one or more processing chambers,a second fluid opening for fluid access to at least one of said processing chambers of the second component, said second fluid opening formed in a flexible portion of the second component that is at least flexible in a direction perpendicular to the second sealing surface, anda second sealing surface associated with the second fluid opening,the first and second components are moveable relative to each other when the first component is connected to the second component to selectively position the first and second fluid openings in (i) an open fluid communication position, wherein the first fluid opening is generally aligned with the second fluid opening to allow the fluid to move between the first component and the second component, and (ii) a closed fluid communication position, wherein the first fluid opening is unaligned with the second fluid opening to prevent the fluid from moving between the first component and the second component; and
a biaser for biasing the second sealing surface toward the first sealing surface to engage the second sealing surface with the first sealing surface to provide a sealed fluid pathway between the first and second components, thereby preventing fluid from leaking external to said cartridge.

Abstract
The present invention relates to a cartridge for the detection of the presence, absence and/or amount of a target nucleotide sequence in a sample comprising one or more nucleic acid sequences. The cartridge comprises a first component and a second component being connectable to each other, the first component comprising at least a first fluid opening and a first sealing surface and the second component comprising at least a second fluid opening and a second sealing surface. Upon connection of the first and second component the first and second fluid opening are placeable in fluid communication and the first and second sealing surfaces are placeable against each other to seal the fluid communication between the first and second fluid opening. The invention is characterized in that the cartridge comprises biasing means for biasing the second sealing surface in the direction of the first sealing surface.

14. A cartridge for the detection of the presence, absence and/or amount of a target nucleotide sequence in a sample comprising one or more nucleic acid sequences, the cartridge comprising:
-
a first component for processing a fluid having a sample, said first component including; one or more processing chambers, a first fluid opening for fluid access to at least one of said processing chambers of the first component, and a first sealing surface associated with the first fluid opening; a second component connectable to the first component for processing the fluid, said second component including; a disk shaped body including at least one flexible portion, one or more processing chambers located within the disk shaped body, a second fluid opening formed in the at least one flexible portion, the second fluid opening providing fluid access to at least one of said processing chambers of the second component, and a second sealing surface associated with the second fluid opening, the first and second components moveable relative to each other when the first component is connected to the second component, for selectively positioning the first and second fluid openings in (i) an open fluid communication position, wherein the first fluid opening is generally aligned with the second fluid opening to allow the fluid to move between the first component and the second component, and (ii) a closed fluid communication position, wherein the first fluid opening is unaligned with the second fluid opening to prevent the fluid from moving between the first component and the second component; and a biaser for biasing the second sealing surface toward the first sealing surface to engage the second sealing surface with the first sealing surface, wherein engagement of said first sealing surface with said second sealing surface provides a sealed fluid pathway between the first and second components, thereby preventing the fluid from leaking external to said cartridge. - View Dependent Claims (15, 16, 17, 18)
