Abstract

A cartridge for a testing device and method of testing using the testing device with the cartridge is disclosed. The cartridge includes a plurality of lancet needles, a plurality of test strips, and a mechanism allowing the cartridge to be mounted to the testing device. The method provides for puncturing a surface of skin using the testing device by arranging the testing device against a user'"'"'s skin, triggering the testing device so that one of the plurality of lancet needles is caused to penetrate the user'"'"'s skin, placing an amount of blood on one of the plurality of test strips, and rotating the cartridge to another position.

Claims

1. A combination comprising:

a rotatably mountable cartridge comprising;

a plurality of lancet needles each comprising a needle portion that is radially oriented;

a plurality of test strips each comprising electrical contacts having portions structured and arranged to be exposed to a user'"'"'s blood drop; and

a testing device comprising;

a cartridge receiving area; and

a testing area visible and accessible from outside the testing device,

wherein, when the cartridge is installed on the testing device while resting on a horizontal surface, the portions of the electrical contracts exposed to a user'"'"'s blood drop extend into the testing area and are visible and accessible to a user from a position above the testing device.

2. The combination of claim 1, wherein each of the plurality of test strips is generally radially oriented.

3. The combination of claim 1, wherein each of the plurality of lancet needles is movably mounted to a disk-shaped body.

4. The combination of claim 1, wherein each of the plurality of test strips is non-movably mounted to a disk-shaped body.

5. The combination of claim 1, wherein the cartridge has an outer diameter of no greater than about 2 inches.

6. The combination of claim 1, wherein the cartridge has a thickness of no greater than about 0.25 inches.

7. The combination of claim 1, further comprising a plurality of springs, wherein each spring is mounted to one of the plurality of lancet needles.

8. The combination of claim 1, wherein each of the plurality of lancet needles comprises a head portion.

9. The combination of claim 1, further comprising a ring-shaped member arranged on the cartridge, wherein each needle portion is arranged within an opening of the ring-shaped member.

10. A method of puncturing a surface of skin using the combination of claim 1, the method comprising:

placing a finger in the visible and accessible testing area;

triggering the testing device so that one of the plurality of lancet needles is caused to penetrate the user'"'"'s skin; and

placing an amount of blood on one of the plurality of test strips.

11. A testing device comprising:

a housing; and

a generally disk-shaped cartridge comprising a plurality of lancet needles and a plurality of test strips,

said cartridge being capable of being removably and rotatably mounted within the housing,

wherein the housing has a testing area that is visible and accessible to a user such that, when the cartridge is installed in the housing and when the testing device is resting on a horizontal surface, portions of electrical contacts of one of the test strips are exposed to a user'"'"'s blood drop and extend into the testing area so as to be visible and accessible from a position above the testing device.

12. A combination comprising:

a generally circular cartridge comprising;

an outer circumference;

a plurality of test strips each comprising electrical contacts having portions structured and arranged to be exposed to a user'"'"'s blood drop;

a testing device comprising;

a cartridge receiving area; and

a testing area arranged outside a housing of the testing device;

wherein, when the cartridge is installed on the testing device while resting on a horizontal surface, at least one of;

a portion of the outer circumference extends outside the housing and portions of electrical contacts are exposed, accessible and visible from outside the testing device; and

portions of electrical contacts extend into the testing area and are each accessible to a user an visible from a position above the testing device.
