LANCING DEVICES HAVING DEPTH ADJUSTMENT ASSEMBLY
First Claim
1. A lancing device for use with a lancet, comprising:
- a housing having a longitudinal axis;
a carriage slidably disposed within the housing;
a lancet carrier having a mouth configured to directly receive and hold the lancet, the lancet carrier engaged within the carriage and movable relative to and independently of the carriage between a forward incision position and a rearward cocked position; and
a trigger assembly comprising;
a first portion accessible from external the housing in a fixed position relative to the longitudinal axis, the first portion movable between a first position and a second position a greater distance from the longitudinal axis than the first position; and
a second portion disposed within the housing and movable along the longitudinal axis, the second portion of the trigger assembly in fixed relation with the carriage such that the carriage and second portion move together along the longitudinal axis, wherein the lancet carrier is configured to move to the rearward cocked position when a lancet is inserted into the housing until the first portion of the trigger assembly is in the second position.

Abstract
Lancing devices are disclosed having a carriage slidably disposed within the housing and a lancet carrier configured to directly receive and hold the lancet. The lancet carrier is engaged within the carriage and movable relative to and independently of the carriage between a forward incision position and a rearward cocked position. A trigger assembly has a user accessible first portion and a second portion attached to the carriage and movable with the carriage along the longitudinal axis. The second portion is configured to maintain the lancet carrier in the rearward cocked position and the first portion is configured to release the lancet carrier from the rearward cocked position.

21. A method of cocking a lancing device comprising:
-
inserting a lancet into a housing having a longitudinal axis so that the lancet is received directly in a lancet carrier that is engaged within a carriage slidably disposed within the housing, the lancet carrier movable relative to and independently of the carriage between a forward incision position and a rearward cocked position; moving the lancet carrier to the rearward cocked position by further inserting the lancet so that the lancet carrier moves along the longitudinal axis while the carriage and a trigger assembly remain fixed relative to the longitudinal axis, wherein the trigger assembly has a user accessible first portion movable substantially perpendicular to the longitudinal axis and a second portion movable with the carriage along the longitudinal axis, wherein the lancet carrier is in the rearward cocked position when the first portion is moved away from the longitudinal axis.
