DEVICE FOR MEASURING ANALYTE CONCENTRATION IN A FLUID

摘要

A test device for testing of analyte concentration in a fluid comprises: a housing (2) having an opening and containing a stack of sensors (16); a transport member (4) rotatably mounted in the opening of the housing, having an axis of rotation which spans the opening; a spring (24) which urges the stack agaisnt the transport member; and sealing means (20, 34) for making a moisture tight seal between the transport member and the sensors when the transport member is in a specified rotational position. An outer surface of the transport member has a recessed region (12) which is adapted to receive a single sensor from the stack. Rotation of the transport member with a sensor in the recessed region transports the sensor to a location where it can be connected to a meter (6, 8) and receive a drop of fluid to be tested.
