1. An integrated diagnostic instrument for analyzing a fluid sample, comprising:
- a housing having an exterior and a sensor opening formed therein;
a sensor pack having a plurality of sensor cavities, each of the plurality of sensor cavities being adapted to house a test sensor therein, the test sensor being adapted to assist in the determination of an analyte concentration in the fluid sample;
a disk drive mechanism disposed in the housing and moveable between a standby position, an extended position, and a testing position, the disk drive mechanism removing a test sensor from the sensor pack and partially ejecting the test sensor through the sensor opening of the housing as the disk drive mechanism is moved between positions; and
a lancing mechanism having(i) a lance holder adapted to removably engages a base of a lance,(ii) a plunger coupled to the lance holder, the plunger having a central portion,(iii) a shaft running through the central portion of the plunger, the plunger being adapted to move along the shaft, the shaft having an end portion that is adapted to secure the shaft to the integrated diagnostic instrument,(iv) a spring at least partially surrounding the shaft, the spring being located between the plunger and the end portion of the shaft, and(v) a slider located on a rail on the exterior of the housing, the slider being adapted to move along the rail in a first direction to compress the spring and wherein the decompressing of the spring causes the plunger and lance holder to rapidly move in a second direction opposite the first direction.

Abstract
An integrated diagnostic instrument (10) for analyzing a fluid sample includes a housing (12), a sensor pack (122), a disk drive mechanism (200) and a lancing mechanism (16). The lancing mechanism includes a lance holder (110) adapted to removably engage a base of a lance (86), a plunger (66) coupled to the lance holder, a shaft (70) running through a central portion of the plunger, a spring at least partially surrounding the shaft, and a slider (90) located on a rail on the exterior of the housing.

10. A method for collecting and analyzing a concentration of an analyte in a fluid sample, comprising the acts of:
-
mounting a sensor pack on an indexing disk within a housing of an integrated diagnostic instrument, the sensor pack having a plurality of sensor cavities each being adapted to house a test sensor therein, the test sensor being adapted to assist in the determination of an analyte concentration in the fluid sample; actuating a disk drive mechanism to remove a test sensor from the sensor pack and partially eject the test sensor through a sensor opening of the housing; lancing the skin of a test subject with a lancing mechanism to obtain a fluid sample, the lancing mechanism at least partially contained within the housing of the integrated diagnostic instrument, the integrated diagnostic instrument being in a first position when lancing; moving the integrated diagnostic instrument from the first position to a second position; applying the obtained fluid sample from the test subject to the partially ejected test sensor, the integrated diagnostic instrument being in the second position when applying the obtained fluid sample; and determining the analyte concentration of the fluid sample. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
