Body fluid sampling device and methods of use
First Claim
1. An incision-forming member carrier comprising:
- an adapter sleeve, the adapter sleeve having means for releasably securing the adapter sleeve within a housing member;
an incision-forming member carrier sleeve means coaxially received within the adapter sleeve for releasably securing a disposable incision-forming member therein; and
a stimulator means coaxially received within the adapter sleeve for depressing a ring of body tissue surrounding an incision formed by the incision-forming member such that by repeatedly applying and releasing a downward force to the stimulator means a sample of body fluid is expressed from the incision.

Abstract
A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user'"'"'s skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.

11. An incision-forming member carrier comprising:
-
an adapter sleeve, the adapter sleeve having formations adapted to releasably securing the adapter sleeve within a housing member; an incision-forming member carrier sleeve coaxially received within the adapter sleeve adapted to releasably secure a disposable incision-forming member therein; and a stimulator sleeve coaxially received within the adapter sleeve, the stimulator sleeve adapted to depress a ring of body tissue surrounding an incision such that by repeatedly applying and releasing a downward force to the stimulator sleeve a sample of body fluid is expressed from the incision. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of obtaining a sample of body fluid comprising:
-
(i) providing a body fluid sampling device, the body fluid sampling device comprising a housing, an incision-forming member carrier releasably retained within the housing, the incision-forming member carrier including a stimulator member, and a disposable incision-forming member, the disposable incision forming member including a sample-drawing member; (ii) forcing the incision-forming member out of the housing such that an incision is formed on a skin surface; (iii) forming a ring of depressed body tissue about the incision by engaging a skin surface with an end of the stimulator member, then repeatedly applying and releasing a downward force to the stimulator member such that a sample of body fluid is expressed from the incision; (iv) bringing the sample-drawing member into communication with the body fluid sample, and transporting the body fluid sample away form the skin surface with the sample drawing member; (v) removing the carrier from the housing; (vi) removing the disposable incision-forming member from the carrier; (vii) replacing the disposable incision-forming member by releasably mounting a new disposable incision-forming member in the carrier; and (viii) releasably securing the carrier within the housing. - View Dependent Claims (22, 23, 24)
