Measurement arrangement for multiple zone removable sensors
First Claim
1. A measurement arrangement for use with a multiple zone removable sensor disposed at least partially within the measurement arrangement, said measurement arrangement including means for applying an electrical signal to said sensor to produce a measurement signal and a cutting device for cutting a zone from said multiple zone removable sensor after the zone has been brought into contact with a sample to effect a measurement, said cutting comprising:
- a lever fixed to a first axle pivotable about a first axis;
a second axle having a second axis, said second axle being movable about said first axle;
a crank having a first end coupled to said second axle and freely pivotable about said second axis, said crank having a second end to which a blade is mechanically coupled;
means for mechanically coupling said first axle to said second axle whereby pivoting of said lever causes movement of said crank; and
,a guide for guiding said second end of said crank along a path so that said second end of said crank moves toward and away from a multiple zone removable sensor as said lever is pivoted in a first and a second direction, respectively, whereby said blade cuts a multiple zone removable sensor disposed in said path and said blade is then retracted.

Abstract
A measurement arrangement, in particular for measuring the proportion of glucose in the blood, which is intended to be associated with a removable sensor including a plurality of single use active zones includes a cutting arrangement (44, 64, 66, 68, 70) serving to cut off the removable sensor (52) introduced into the measurement arrangement. The cutting arrangement comprises a lever (44), a crank (66) and a blade (70) fixed on the lever.

11. A measurement arrangement for use with a multiple zone and generally planar removable sensor that may be disposed in a first plane and at least partially within the measurement arrangement, the measurement arrangement including means for applying an electrical signal to said sensor to produce a measurement signal and a cutting device for cutting a zone from said multiple zone removable sensor after the zone has been brought into contact with a sample to effect a measurement, said cutting comprising:
-
a lever fixed to a first axle so as to pivot about a first axis; a second axle having a second axis, said second axle being movable about said first axle; a crank having a first end coupled to said second axle, said crank being freely pivotable about said second axis; means for mechanically coupling said first axle to said second axle; a blade mechanically coupled to a second end of said crank; and
,a guide for guiding said second end of said crank along a guide path whereby said blade moves in a cutting direction parallel to the first plane in which a sensor is disposed to thereby cut a sensor as said lever is pivoted about said first axis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
