Problems solved by technology

This can lead to inaccurate results in the case of large volume samples retaining low concentrations of the desired analyte
Finally, the complexity of the cartridge makes the device more difficult to operate by unskilled users in the field

Embodiment Construction

[0069] FIG. 1 shows a device 2 according to the invention comprising a sample chamber 4 , a first buffer chamber 6 with a first piston 8 , a second buffer chamber 10 with a second piston 12 . The first piston 8 and the second piston 12 include sockets 34 to allow their integration with external equipment to move the pistons during use. The device 2 also includes a small volume water chamber 14 which extends beyond the body of the device 2 . The small volume water chamber may include a membrane seal surrounding the chamber so that the water in the chamber does not vaporize during storage or early stages of sample processing. The film is, for example, a thin plastic sheet of 0.1-0.2 mm with a skin made of acrylonitrile butadiene styrene. The device also comprises a first outlet portion 16 and a second outlet portion 18 through which one or more vacuums can be connected to the device 2 . The sample chamber 4 comprises a cover 20 mounted on the body of the device 2 by means of a...

Abstract

This invention relates to an apparatus for an apparatus for processing a fluid sample comprising: (i) a sample processing chamber comprising a fluid inlet and a fluid outlet; (ii) a waste chamber downstream from the sample processing chamber and in fluid communication with the sample processing chamber fluid outlet and wherein the fluid communication between the sample processing chamber outlet and the waste chamber comprises a divergent analyte flow path; (iii) at least two further chambers up stream from the sample processing chamber both of which are in fluid communication with the sample processing chamber fluid inlet; (iv) a means for moving fluid from each of the at least two further chambers through the sample processing chamber and into the waste chamber or into the divergent analyte flow path as desired by applying positive or negative pressure to the desired flow path; and (v) a passive means for restricting the flow of fluid. This invention also relates to a method and use of the same.

Description

technical field [0001] The present invention relates to an apparatus for processing a fluid sample and an associated method. Background technique [0002] Fluid samples (eg, clinical or environmental samples) may be analyzed for a variety of reasons. An area of ​​current interest is the development of methods for the correct identification of biological materials in fluid samples (eg, clinical or environmental samples). It is important because it will aid in the early diagnosis of conditions so that rapid treatment and infection control can be done, or in the identification of environmental pollutants, etc. Although nucleic acid amplification (e.g., polymerase chain reaction (PCR)) is a very useful and commonly used method for the correct identification of biological material, it is difficult to Problems arise when rapidly identifying biological material in an individual fluid sample, such as in the vicinity of a patient or site of disease diagnosis of interest. [0003] ...
