Abstract

A meter system for analyzing body fluids includes a supply magazine for storing a stack of test elements, a meter for analyzing fluid samples, and a transport system for transporting test elements from the supply magazine to the meter. The test element in one embodiment includes a lancet integrated test element that has a lancet coupled to a test strip. The transport system is configured to minimize damage to the test element. In one form, the transport system includes a shuttle that slides the top-most test element from the stack onto a connection portion of the meter. In another form, the transport system includes a drum that rotates to transport test elements from the supply magazine to a testing position and, once used, to a waste magazine for disposal. In a further form, the transport system includes a disc that rotates to transport the test elements.

a lancet coupled to the test strip for forming an incision where the body fluid sample is drawn, the lancet being configured to extend proximal the sample opening;

a meter having a connector portion configured to operatively couple to the lancet integrated test element, the meter being configured to fire the lancets on the lancet integrated test elements;

a transport mechanism to transfer the lancet integrated test elements to the connector portion of the meter, wherein the transport mechanism being configured to engage at least one of the side edges to minimize risk of damaging the test strip and the lancet proximal the sample opening of the lancet integrated test element;

wherein the transport mechanism includes a disc that defines a test element cavity in which the lancet integrated test elements are received;

wherein the disc includes at least a pair of grip members configured to grip opposing side edges of the lancet integrated test elements in between;

a second disc including at least a pair of lock pins;

the disc with the grip members being capable of moving independently of the second disc with the lock pins; and

the lock pins being engageable with the grip members to grip the at least one of the lancet integrated test elements by the opposing side edges of the test strip.

2. The system of claim 1, wherein:

the meter includes a motor coupled to the disc; and

the motor is configured to rotate both the disc and the second disc when the lock pins engage the grip members.

3. The system of claim 1, wherein:

the meter defines a relief notch proximal the connector to promote fluid collection; and

the disc defines a relief notch that is alignable with the relief notch of the meter during fluid collection.

4. The system of claim 1, wherein:

the test element has a connector end; and

the test element cavity has a beveled cavity that is angled to extend the connector end of the test element from the second disc for engaging the connector end of the test element to the connector of the meter.

5. A system, comprising:

a supply magazine configured to store a stack of test elements, each of the test elements including opposing surfaces where the test elements are stacked on one another, each of the test elements having opposing side edges that extend between the opposing surfaces;

a meter including a connector configured to connect to the test elements;

a transport system configured to transport test elements from the supply magazine to the connector of the meter;

the transport system including a disc-shaped transport member configured to receive at least one of the test elements from the magazine;

the disc-shaped transport member being rotatable relative to the meter to transport the at least one of the test elements to the connector;

wherein the disc-shaped transport member includes a first disc that includes at least one lock pin;

wherein the disc-shaped transport member includes a second disc that includes at least one grip member;

wherein the first disc is capable of rotating independently of the second disc; and

wherein the lock pin on the first disc is engageable with the grip member on the second disc to grip the at least one of the test elements;

the first disc includes a pair of the lock pins; and

the second disc includes a pair of the grip members, the lock pins being configured to compress the grip members in an inward direction to grip the opposing side edges of the at least one of the test elements in between.

6. The system of claim 5, wherein:

the meter includes a motor coupled to the first disc; and

the motor is configured to rotate both the first disc and the second disc when the lock pin engages the grip member.

7. The system of claim 5, wherein:

the second disc defines a test element cavity in which the test elements are received.

8. The system of claim 7, wherein:

the test element has a connector end; and

the test element cavity has a beveled cavity that is angled to extend the connector end of the test element from the second disc for engaging the connector end of the test element to the connector of the meter.

9. The system of claim 5, wherein:

the meter defines a relief notch proximal the connector to promote fluid collection; and

the disc-shaped transport mechanism defines a relief notch that is alignable with the relief notch of the meter during fluid collection.

10. The system of claim 5, wherein the test elements are lancet integrated test elements that include lancets and test strips.

11. The system of claim 5, wherein:

the first disc includes a pair of the lock pins; and

the connector portion of the meter has electrical contacts; and

wherein the disc-shaped transport mechanism is configured to insert the test element into the connector portion of the meter to operatively connect the electrical contacts of the test elements.

13. The system of claim 5, further comprising:

the first disc being rotatable while the second disc remains stationary to disengage the lock pin from the grip member for releasing the test element when connected to the connector.

14. A system, comprising:

a supply magazine configured to store a stack of test elements, each test element having opposing side edges that extend between the opposing surfaces;

a meter including a connector configured to connect to the test elements; and
