Detection meter and mode of operation

摘要

A method for performing an assay to determine the presence or concentration of an analyte contained in a sample of body fluid by using a device comprising at least one analyte quantification member and a sensor associated therewith, the method includes: applying a first sample to the analyte quantification member; and detecting the presence or absence of an adequate sample volume; wherein upon detection of the absence of an adequate sample volume, initiating a finite timed period, and signaling the user to introduce a second sample of body fluid to the analyte quantification member. Associated arrangements and devices are also disclosed.

主权项

1. A device for performing an assay to determine the presence or concentration of an analyte contained in a sample of body fluid, the device comprising:
at least a first analyte quantification member; at least one passageway in fluid communication with the first analyte quantification member; a sensor configured to interrogate at least the first analyte quantification member and to detect the presence or absence of an adequate sample volume; a vacuum source configured to assist in the expression of body fluid from a wound; a non-transitory memory device programmed with instructions to:
activate the vacuum source;initiate a first time period and interrogate the first analyte quantification member using the sensor to detect the presence or absence of an adequate sample volume applied to the first analyte quantification member within the first time period; andupon the detection of the absence of an adequate sample volume, initiate a second time period and signal a user to manually milk the wound and introduce an additional sample of body fluid into the at least one passageway to increase the sample volume applied to the first analyte quantification member; and a processor programmed to carry out the instructions on the non-transitory memory device.
