Biologic fluid analysis cartridge

摘要

A biological fluid sample analysis cartridge is provided. The cartridge includes a housing, a fluid module, and an analysis chamber. The fluid module includes a sample acquisition port and an initial channel, and is connected to the housing. The initial channel is sized to draw fluid sample by capillary force, and is in fluid communication with the acquisition port. The initial channel is fixedly positioned relative to the acquisition port such that at least a portion of a fluid sample disposed within the acquisition port will draw into the initial channel. The analysis chamber is connected to the housing, and is in fluid communication with the initial channel.

1. A biological fluid sample analysis cartridge, comprising:
a fluid module having a sample acquisition port, an initial channel, and a second channel, and which initial channel is sized to draw fluid sample by capillary force, and which initial channel is in fluid communication with the acquisition port and is fixedly positioned relative to the acquisition port such that at least a portion of a fluid sample disposed within the acquisition port will draw into the initial channel; and an analysis chamber attached to an imaging tray, which imaging tray is slidably received within the cartridge and selectively positionable relative to the cartridge in a first position and in a second position, and in the second position the analysis chamber is positioned to receive fluid from the secondary channel; and wherein the secondary channel is fluidically disposed between the initial channel and the analysis chamber such that fluid sample exiting the initial channel must pass through the secondary channel before entering the analysis chamber; and wherein an intersection between the initial channel and the secondary channel prevents capillary forces from drawing sample out of the initial channel and into the secondary channel.
