Embodiment Construction

[0047] figure 1 Shown is a cassette 1 for performing diagnostic tests. The cartridge 1 is configured to be inserted into a diagnostic device to perform an analysis of, for example, a blood sample. The cartridge 1 in this embodiment is substantially planar and includes a hole 3 . In use, reagent 4 is dissolved in liquid 5 in well 3 . The liquid 5 may comprise, for example, wet reagents stored in a reservoir (not shown) provided on the cartridge 1 . A disposable container 6 may be fitted to the cartridge 1, for example to deliver a test sample.

[0048] Cassette 1 comprises a storage device 10 according to an embodiment of the invention. The reagents 4 for diagnostic tests are stored in the storage device 10 . Storage device 10 may be selectively actuated to release reagent 4 as described herein. In this example, reagent 4 is a dry reagent and is formed as beads, such as lyophilized beads. It should be understood that other types and forms of reagents 4 may also be stored...

Abstract

A device is provided for preserving the integrity of one or more reagents on a substantially planar cartridge. The device comprises a chimney extending substantially perpendicular to the plane of the cartridge,a bead holder encapsulated within the chimney; and a piercing mechanism located within the chimney and configured to enable a bead to access the bead holder, in use.

Description

technical field [0001] The present disclosure relates to a storage device. Aspects of the invention relate to a device for maintaining the integrity of one or more reagents; and also to a cartridge comprising a device for maintaining the integrity of one or more reagents . Background technique [0002] It is known to store dry and wet reagents on diagnostic cartridges. Dry reagents can include, for example, lyophilized beads. For example, dry reagents may be exposed to moisture in the form of vapor from wet reagents. The integrity of the reagents may be adversely affected by moisture intrusion, especially during prolonged storage. It has been recognized that it is desirable to reduce the rate of moisture vapor transfer from wet to dry reagents. Furthermore, if there is no effective seal between the components, amplicons may move between different areas of the cartridge, leading to contamination. [0003] It is an object of the present invention to address one or more o...
