Abstract
Abstract A sampling device for sampling body fluid includes a casing which is pressed against a skin surface to produce a seal therewith. A cocking mechanism is pulled rearwardly to place a lancing device in a cocked state. By releasing a trigger, the lancing device is driven forward to produce an incision in the skin, and then is retracted out of the incision. A plunger mounted on the cocking mechanism is then retracted to generate a negative pressure at the front end of the casing to draw body fluid from the incision.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A sampling device for sampling body fluid, comprising: a casing defining a longitudinal axis; a skin-lancing mechanism for extending a lance through a longitudinal front end of the casing and against a skin surface to form an incision therein, and then retracting the lance back into the housing; a trigger for releasably holding the skin-lancing mechanism in a cocked state; an actuator for displacing the trigger to a release position for releasing the skin-lancing mechanism; and a plunger separated from the actuator and being longitudinally rearwardly movable relative to both the skin-lancing mechanism and the actuator the plunger being constructed and arranged with the sampling device such that a negative pressure is generated at the front end of the casing by movement of the plunger away from the front end of the casing, the negative pressure acting to draw body fluid from the incision.
Claim 2
Dependent Claim
144 words
A sampling device for sampling body fluid, comprising: a casing defining a longitudinal axis; a skin-lancing mechanism for extending a lance through a longitudinal front end of the casing and against a skin surface to form an incision therein, and then retracting the lance back into the housing; a trigger for releasably holding the skin-lancing mechanism in a cocked state; an actuator for displacing the trigger to a release position for releasing the skin-lancing mechanism; and a plunger separated from the actuator and being longitudinally rearwardly movable relative to both the skin-lancing mechanism and the actuator the plunger being constructed and arranged with the sampling device such that a negative pressure is generated at the front end of the casing by movement of the plunger away from the front end of the casing, the negative pressure acting to draw body fluid from the incision.
Claim 3
Dependent Claim
24 words
The sampling device according to claim 1 wherein the plunger is spring biased in a direction away from the front end of the casing.
Claim 4
Dependent Claim
129 words
A sampling device for sampling body fluid, comprising: a casing defining a longitudinal axis; a skin-lancing mechanism for extending a lance through a longitudinal front end of the casing and against a skin surface to form an incision therein, and then retracting the lance back into the housing; a trigger for releasably holding the skin-lancing mechanism in a cocked state; an actuator for displacing the trigger to a release position for releasing the skin-lancing mechanism; and a plunger spring-biased in a direction away from the front end of the casing and arranged separated from the actuator and being longitudinally rearwardly movable relative to both the skin-lancing mechanism and the actuator for generating a negative pressure at the front end of the casing to draw body fluid from the incision.
