Abstract

A sensor dispensing instrument comprises a housing, a sensor pack, a sensor, and a knife blade assembly. The sensor pack is disposed within the housing and has a sensor cavity and a protective covering. The sensor is disposed within the sensor cavity. The knife blade assembly is operably disposed within the housing and has a serrated edge for cutting the protective covering.

Claims

1. A sensor dispensing instrument comprising:

a housing;

a sensor pack disposed within said housing having a sensor cavity and a protective covering;

a sensor disposed within said sensor cavity; and

a knife blade assembly operably disposed within said housing and having a serrated edge for cutting said protective covering.

2. The sensor dispensing instrument of claim 1, wherein said knife blade assembly is operably disposed to puncture said protective covering and eject said sensor from said sensor cavity.

3. The sensor dispensing instrument of claim 1, wherein said protective covering is foil.

4. The sensor dispensing instrument of claim 1, wherein said serrated edge has a plurality of curved segments.

5. The sensor dispensing instrument of claim 1, wherein said knife blade assembly further comprises a plastic body and a blade fastened to said body.

6. The sensor dispensing instrument of claim 5, wherein said blade is insert molded into said body.

7. The sensor dispensing instrument of claim 1, wherein said sensor pack has a circular shape and a plurality of circumferentially arranged sensor cavities.

8. A sensor dispensing instrument configured to be used with 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 covering, said sensor dispensing instrument further adapted to perform a test using one of said plurality of sensors, and comprising a knife blade assembly having a serrated edge for puncturing and cutting said protective covering and ejecting one of said sensors from said sensor cavity.

9. The sensor dispensing instrument of claim 8, wherein said protective covering is foil.

10. The sensor dispensing instrument of claim 8, wherein said sensor pack has a circular shape and a plurality of circumferentially arranged sensor cavities.

11. The sensor dispensing instrument of claim 8, wherein said serrated edge has a plurality of curved segments.

12. The sensor dispensing instrument of claim 8, wherein said knife blade assembly further comprises a plastic body and a blade fastened to said body.

13. The sensor dispensing instrument of claim 8, wherein said blade is insert molded into said body.

14. A method of making a knife assembly for a sensor dispensing instrument, the method comprising the acts of:

providing a metal sheet;

fabricating a knife from said metal sheet;

etching a serrated cutting edge on said knife; and

molding a plastic body around said knife.

15. The method of claim 14, wherein said step of fabricating a knife from said metal sheet is performed by chemical etching.

16. The method of claim 14, wherein said serrated cutting edge has a plurality of curved segments.

17. The method of claim 14, wherein said knife assembly is assembled into a sensor dispensing instrument.
