Apparatus for sampling body fluid

摘要

Body fluid is sampled by causing a syringe (26) mounted in a housing (12) to be displaced towards a skin surface. The syringe (26) remains in the resulting incision while the surrounding body tissue is stimulated by a stimulator ring (70) to urge body fluid towards the incision. Simultaneously, the syringe (26) is moved relative to the incision to keep the incision open.
