Abstract

An integrated monitoring and body fluid sampling device constructed to permit digital as well as alternate-site body fluid sampling and analysis, the device comprising: a housing; at least one skin-penetration member; and a member constructed for the application of circumferential or vacuum pressure to an appendage; wherein the member is detachably or retractably connected to the housing in a manner such that the integrated monitoring and body fluid sampling device can perform digital or alternate-site body fluid sampling and analysis. Additional arrangements and techniques are also described.

Claims

1-38. -38. (canceled)

39. A method for sampling a body fluid from a digit:

positioning the digit between a first arm and a second arm of a catalyst device;

moving the digit relative to the catalyst device to apply pressure to the digit with the catalyst device near a sampling site of the digit; and

piercing the sampling site with a skin penetration member of a sampling device to collect a sample of the body fluid.

40. The method of claim 39 wherein the sampling device comprises a housing, wherein the housing comprises a footprint.

41. The method of claim 40 further comprising positioning the digit relative to the footprint.

42. The method of claim 39 wherein the catalyst device comprises a U-shaped channel comprising the first and second arms.

43. The method of claim 39 wherein the sampling device comprises a mechanism for moving the catalyst device relative the digit, and wherein moving the digit relative to the catalyst device comprises moving the catalyst device with the mechanism.

44. The method of claim 43 wherein the mechanism comprises a motor and a linkage connecting the catalyst device to the linkage.
