Abstract
A lancet integrated test element (LIT) includes an incision forming member that has a cutting end configured to form an incision in tissue. A test element is attached to the incision forming member to test fluid from the incision. The test element has a sampling end with a sample opening through which the fluid is collected. The test element is bendable from a first state where the cutting end of the incision forming member is retracted from the sampling end of the test element to a second state where at least a portion of the cutting extends past the sampling end of the test element to form the incision in the tissue.
Claims19
An apparatus, comprising:
- an integrated lancing test device comprising
- an incision forming member configured to form an incision in tissue, and
- a test element attached to the incision forming member for testing fluid from the incision, wherein the test element is bendable to expose the incision forming member during formation of the incision;
- and
- a lancing mechanism comprising a holder to which the integrated device is coupled, the holder comprising one or more stops to prevent excessive bending of the test strip during lancing.
An apparatus, comprising:
- an incision forming member having a cutting end configured to form an incision in tissue;
- a test element attached to the incision forming member to test fluid from the incision;
- the test element having a sampling end with a sample opening through which the fluid is collected;
- the test element being bendable from a first state where the cutting end of the incision forming member is retracted from the sampling end of the test element to a second state where at least a portion of the cutting extends past the sampling end of the test element to form the incision in the tissue;
- and
- a holder comprising one or more stops to prevent excessive bending of the test element during lancing.
An apparatus, comprising:
- an incision forming member having a cutting end configured to form an incision in tissue;
- a test element attached to the incision forming member to test fluid from the incision;
- the test element having a sampling end with a sample opening through which the fluid is collected;
- the test element being bendable from a first state where the cutting end of the incision forming member is retracted from the sampling end of the test element to a second state where at least a portion of the cutting extends past the sampling end of the test element to form the incision in the tissue;
- and
- a lancing mechanism configured to fire the incision forming member.
A method, comprising:
- providing a lancet integrated test strip that includes a lancet attached to a test strip, wherein a cutting end of the lancet extends proximal a sampling end of the test strip that includes a sample chamber opening;
- forming an incision in tissue with the lancet integrated test strip;
- wherein said forming the incision includes bending the test strip by pressing the sampling end of the test strip against the tissue to extend the cutting end of the lancet past the sampling end of the test strip and into the tissue;
- and
- sampling fluid from the incision by drawing fluid into the sample chamber opening of the test strip.
