Patent ID: 7766845

Claim:
An apparatus, comprising: a disposable body fluid testing cartridge including an incision forming member for forming an incision in skin, the incision forming member having a tab that extends laterally from the incision forming member for controlling movement of the incision forming member as the incision forming member is extended and retracted during formation of the incision, a housing defining a side opening through which the tab extends for controlling penetration depth of the incision forming member into the skin, connectors attaching the incision forming member to the housing to form one molded body, the connectors being flexible to facilitate folding of the incision forming member against the housing, wherein the connectors are positioned to align the tab of the incision forming member with the opening in the housing as the incision forming member and housing are folded together about the connectors, the incision forming member and the housing being folded together with the connectors being bent, the tab of the incision forming member extending laterally through the opening of the housing, the opening of the housing configured to limit movement of the tab, a test strip attached to the housing for analyzing body fluid from the incision in the skin, the test strip having an expression surface configured to express the body fluid from the incision when pressed against the skin, wherein the housing has a first cavity wall and the test strip has a second cavity wall, the first cavity wall of the housing and the second cavity wall of the test strip defining a capillary cavity configured to draw body fluid onto the test strip via capillary action, the incision forming member being slidably disposed within said capillary cavity; and an actuation mechanism coupled to the tab of the incision forming member for extending and retracting the incision forming member during formation of the incision, the actuation mechanism coupled to the exterior of the housing to engage the tab being extended through the opening.
