A lancet device, comprising: a housing having a proximal end and a distal end; an end cap enclosing the proximal end of the housing; a shield having a proximal end and a distal end, the shield proximal end disposed within the housing, and the shield being movable relative to the housing; a skin puncturing assembly disposed within the housing and comprising a movable carrier and a skin puncturing element, a distal end of the skin puncturing element adapted for puncturing the skin of a patient, the carrier movable between a retracted position where the distal end of the skin puncturing element is disposed within the shield, and a puncturing position where the distal end of the skin puncturing element extends out of the shield in a puncturing position; at least one flexure member being engaged with the carrier to maintain the carrier in the retracted position, and being not engaged with the carrier or released from the carrier in the puncturing position; a drive spring disposed within the housing for biasing the carrier from the retracted position to the puncturing position when the at least one flexure member is not engaged with/released from the carrier, wherein the drive spring biases the carrier toward the distal end of the shield; and a retraction spring disposed within the shield, the retraction spring adapted to return the carrier to a puncturing position within the housing wherein the shield encompasses the skin puncturing element after the carrier reaches the puncturing position, characterised in that the at least one flexure member extends from a surface of the end cap into the housing. a housing having a proximal end and a distal end; an end cap enclosing the proximal end of the housing; a shield having a proximal end and a distal end, the shield proximal end disposed within the housing, and the shield being movable relative to the housing; a skin puncturing assembly disposed within the housing and comprising a movable carrier and a skin puncturing element, a distal end of the skin puncturing element adapted for puncturing the skin of a patient, the carrier movable between a retracted position where the distal end of the skin puncturing element is disposed within the shield, and a puncturing position where the distal end of the skin puncturing element extends out of the shield in a puncturing position; at least one flexure member being engaged with the carrier to maintain the carrier in the retracted position, and being not engaged with the carrier or released from the carrier in the puncturing position; a drive spring disposed within the housing for biasing the carrier from the retracted position to the puncturing position when the at least one flexure member is not engaged with/released from the carrier, wherein the drive spring biases the carrier toward the distal end of the shield; and a retraction spring disposed within the shield, the retraction spring adapted to return the carrier to a puncturing position within the housing wherein the shield encompasses the skin puncturing element after the carrier reaches the puncturing position, characterised in that the at least one flexure member extends from a surface of the end cap into the housing.
