Abstract
Abstract A lancet device has a two part housing (1) integrally molded in a folded-out configuration with a spring (2), a lancet body (3) encasing a needle (4), and a needle cap (5) concealing the needle tip. The spring (2) is a zig-zag connected at one end to one housing part (7) by a web (19) and merging at the other end into the lancet body (3). This is folded over with the spring (2) about the web (19) into the housing part (7), and the other housing part (6) is closer over about web hinges (8) and fastened. A trigger (9) is incorporated in the other housing part (6) and is deformable inwardly to release the lancet body (3) from a catch arrangement (14, 21) which holds the lancet retracted with the spring energized. The needle cap (5) can be used for the retraction before being removed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
A lancet device comprising a housing with a first part and a second part, a spring, a lancet body extending from one end of the spring, a first web joining the first and second parts of the housing so that, as molded, those parts are in a folded-out configuration but which enables said parts to be hinged together, a second web joining the other end of the spring to the first housing part so that, as molded, the spring and lancet body are folded out from said first housing part but which enables the spring and lancet body to be hinged over said first housing part and to be captive within the housing when the two parts are hinged and fastened together, and a trigger on one of the housing parts arranged to retain the lancet body within the housing with the spring compressed when the housing parts are hinged and fastened together, but which is actuable to release the lancet body to cause the exposed tip of a needed embedded therein momentarily to project through an aperture in the housing, the housing parts, the webs, the spring, the lancet body and the trigger all being integrally molded from plastics material.
Claim 2
Dependent Claim
201 words
A lancet device comprising a housing with a first part and a second part, a spring, a lancet body extending from one end of the spring, a first web joining the first and second parts of the housing so that, as molded, those parts are in a folded-out configuration but which enables said parts to be hinged together, a second web joining the other end of the spring to the first housing part so that, as molded, the spring and lancet body are folded out from said first housing part but which enables the spring and lancet body to be hinged over said first housing part and to be captive within the housing when the two parts are hinged and fastened together, and a trigger on one of the housing parts arranged to retain the lancet body within the housing with the spring compressed when the housing parts are hinged and fastened together, but which is actuable to release the lancet body to cause the exposed tip of a needed embedded therein momentarily to project through an aperture in the housing, the housing parts, the webs, the spring, the lancet body and the trigger all being integrally molded from plastics material.
Claim 3
Dependent Claim
25 words
A lancet device as claimed in claim 1, wherein the housing parts are two elongate channel members and the first web is between longitudinal edges.
Claim 4
Dependent Claim
31 words
A lancet device as claimed in claim 2, wherein the spring is a zig-zag formation and the second web joins it to an end of the first part of the housing.
Claim 5
Dependent Claim
44 words
A lancet device as claimed in claim 1, wherein a tear-off cap, initially concealing the needle tip, is integrally molded with the lancet body, part of the cap being accessible outside the housing when that is closed around the lancet body and compressed spring.
Claim 6
Dependent Claim
31 words
A lancet device as claimed in claim 1, wherein the trigger is a tongue deformable inwardly of the housing to co-operate with and disengage catch means holding the lancet body retracted.
Claim 7
Dependent Claim
51 words
A lancet device as claimed in claim 5, wherein the catch means is a toothed finger and a detent, one of these being on the side of the lancet body and the other inside a housing part, the toothed finger having snap engagement with the detent on completion of lancet retraction.
Claim 8
Dependent Claim
39 words
A lancet device as claimed in claim 4, wherein the cap is elongated and is usable, before being removed from the needle tip, to push the lancet body back to temporary retention by catch means releasable by the trigger.
