Test device
First Claim
1. A test device for testing of analyte concentration in a fluid to be applied thereto, the device comprising:
- a) a plurality of sensors arranged in a stack, each of said sensors carrying reagent means for producing an electrical signal in response to the concentration of analyte in an applied fluid, each of said sensors having a plurality of electrode tracks for transmitting said electrical signal;
b) a housing having an opening therein and containing the said stack of sensors;
c) electrical contacts mounted in relation to the housing for engaging with electrode tracks on a sensor at an engagement location;
c) a meter connected to the said electrical contacts, having electronics means for producing a signal output which is dependent on the electrical signal from a sensor when the sensor is engaged with the said contacts;
d) a transport member rotatably mounted in the opening of the housing, having an axis of rotation which spans the opening and having an outer surface which is provided with a recessed region adapted to receive a single sensor from the stack;
e) spring means within the housing which urge the stack of sensors towards the transport member and which urge a single sensor into the said recess when the recess is suitably aligned adjacent to the stack;
f) sealing means for making a moisture tight seal between the transport member and the stack when the transport member is in a specified rotational position; and
g) wherein rotation of the transport member with a sensor in the recessed region will transport the sensor to the engagement location or to a position where the sensor can be moved to the engagement location, whereby electrode tracks of the sensor can engage with the said electrical contacts.

Abstract
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 against 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.
