- 7. The sensor dispensing instrument according to claim 1, wherein the linear drive system includes a belt and a connecting member connected with the belt, wherein the connecting member is connected with and moves the disk drive pusher as the belt is rotated.
- 8. The sensor dispensing instrument according to claim 1, wherein the power transfer system includes at least one gear for transferring power from the motor to the linear drive system.
- 9. The sensor dispensing instrument according to claim 1, wherein the power transfer system includes a roller for transferring power from the motor to the linear drive system.
- 10. A sensor dispensing instrument adapted to handle a sensor pack containing a plurality of sensors, comprising:
an outer housing comprising a sensor opening; a motor generally disposed within the outer housing; a linear drive system generally disposed within the outer housing; a power transfer system connected with the motor and the linear drive system, wherein the power transfer system transfers power from the motor to the linear drive system; and a disk drive mechanism generally disposed within the outer housing and connected with the linear drive system, wherein a sensor is disposed through said sensor opening when said motor is activated.
- 11. The sensor dispensing instrument according to claim 10, wherein the disk drive mechanism includes an indexing disk for supporting and rotating said sensor pack, an indexing disk drive arm for rotating said indexing disk, a knife blade assembly for puncturing said foil covering and ejecting one of said sensors from said sensor cavity and through said sensor opening, and a disk drive pusher on which said indexing disk drive arm and said knife blade assembly are mounted, said disk drive pusher being movable with respect to said outer housing.
- 12. The sensor dispensing instrument according to claim 11, wherein said sensor dispensing instrument is operated by activating the motor so as to cause said indexing disk drive arm to rotate said indexing disk, and so as to cause said knife blade assembly to puncture the foil covering and eject one of said sensors from said sensor cavity and through said sensor opening.
- 13. The sensor dispensing instrument according to claim 10, wherein the linear drive system includes a lead screw and a nut on the lead screw, wherein the nut is connected with and moves the disk drive mechanism as the lead screw is rotated.
- 14. The sensor dispensing instrument according to claim 10, wherein the power transfer system includes at least one gear.
- 15. The sensor dispensing instrument according to claim 10, wherein the sensor dispensing instrument is adapted to perform a test by using a fluid testing sensor, wherein said fluid testing sensor is being supplied by a disposable sensor pack inserted into said sensor dispensing instrument, wherein said sensor pack has a plurality of sensor cavities covered by a protective covering, and wherein said fluid testing sensor is enclosed in one of said sensor cavities prior to the performance of said test.
- 16. A method of operating a sensor dispensing instrument adapted to handle a sensor pack containing a plurality of sensors, each of said plurality of sensors being disposed in a sensor cavity on said sensor pack and enclosed by a protective foil covering, said sensor dispensing instrument further adapted to perform a test using one of said plurality of sensors, said sensor dispensing instrument comprising an outer housing having a sensor opening through which one of said sensors is disposed to conduct the test, and said sensor dispensing instrument further comprising a button, a disk drive mechanism having an indexing disk for supporting and rotating said sensor pack, an indexing disk drive arm for rotating said indexing disk, a knife blade assembly for puncturing said foil covering and ejecting one of said sensors from said sensor cavity and through said sensor opening, and a pusher for moving said indexing disk drive arm and said knife blade assembly, wherein said method comprises the steps of:
a) pressing said button to cause a motor within said sensor dispensing instrument activate, wherein the motor causes said indexing disk drive arm to move and rotate said indexing disk and align the sensor cavity with the sensor opening, and causes the knife blade assembly to puncture the foil covering and eject the sensor from the sensor cavity and through said sensor opening; and b) performing the test by using the sensor disposed in said sensor opening.
- 17. The method of operating a sensor dispensing instrument according to claim 16, further comprising the steps of:
e) viewing test results generated by the test on a liquid crystal display disposed on the outer housing; and f) removing the sensor from the sensor opening.
