Abstract

The present invention provides an analyte test device (5) for determining concentration of an analyte in a physiologic fluid. The analyte test device (5) includes a test meter (7) and a lancet device (10, 110). The lancet device (10,110) has an integral lancet (20,120), a lancet casing (40,140) and a test strip (60). The lancet (20,120) is locked onto the lancet casing (40,140) by a catch (32,132). When the lancet device (10) is inserted into a receptacle (R) on the test meter (7), a spigot (Q) unlocks the catch (32) from the lancet casing (40) so that the lancet (20) takes on the characteristic of a probe (P) that is connected to a lancet firing mechanism disposed in the test meter (7). Alternatively, a collar (C) on the probe (P) disengages the catch (132) from the lancet casing (140) when the lancet device (110) is inserted into the test meter (7).

Claims

1. An analyte test device for testing a physiologic fluid, the device comprising:

a test meter; and

a lancet device having a casing, a lancet and a test strip;

wherein the lancet is disposed and locked inside the casing by a catch, the test strip is disposed on said casing; and

said lancet device is operable to be removeably connected to said test meter via a receptacle on said test meter;

wherein said receptacle is operable to engage with said catch to unlock said lancet from said casing when said lancet device is inserted into said receptacle and to disengage said catch to relock said lancet inside said casing when said lancet device being removed from said receptacle.

2. An analyte test device according to claim 1, wherein said receptacle comprises a spigot, which cooperates with said catch to unlock and lock the lancet inside said casing.

3. An analyte test device according to claim 2, further comprising a collar at a probe, which is coupled to a lancet firing mechanism inside the test meter, and said lancet is operable to be inserted into said collar.

4. An analyte test device according to claim 3, wherein said lancet is inserted into said collar with an interference fit so that the lancet is operable to take on the characteristic of the lancet firing mechanism.

5. An analyte test device according to claim 1, wherein said receptacle comprises a collar at a probe, which is coupled to a lancet firing mechanism inside the test meter, and said lancet is operable to be inserted into said collar.

6. An analyte test device according to claim 5, wherein said lancet is inserted into said collar with an interference fit so that the lancet is operable to take on the characteristic of the lancet firing mechanism.

7. An analyte test device according to claim 1, wherein said lancet is inserted into said casing with a clearance fit.

8. An analyte test device according to claim 1, wherein said lancet has a pointed end, which is sterilized and insert molded but protected by a breakable cap.

9. A kit comprising:

a lancet;

a lancet casing; and

a test strip;

wherein said lancet has a catch, said catch is operable to lock said lancet inside said lancet casing, and said test strip is operable to be attached onto said lancet casing to form a lancet device.

10. A kit according to claim 9, further comprising a test meter, said test meter having a receptacle for receiving said lancet device.

11. A method for determining an analyte in a physiologic fluid, said method comprising:

supplying a lancet device, said lancet device comprises a lancet, a lancet casing and a test strip;

wherein said lancet has a catch that is operable to lock said lancet inside said lancet casing, and said test strip is operable to be attached onto said lancet casing to form a lancet device;

inserting the lancet device into a receptacle of a test meter, wherein said catch is then deactivated and the lancet is operable to take on the characteristic of a lancet firing mechanism disposed inside said test meter;

collecting a physiologic fluid sample and transferring the fluid sample on an analyte sensing end on said test strip; and

obtaining a reading from said test meter.
