ROTARY-ACTUATED MEDICAL PUNCTURING DEVICE
First Claim
1. A medical puncturing device, comprising:
- an actuator having at least one release element extending therefrom;
a shield, the shield and the actuator movably associated with each other; and
a skin puncturing assembly disposed at least partially within the shield, the skin puncturing assembly comprising a carrier and a skin puncturing element mounted to the carrier, a distal end of the skin puncturing element adapted for puncturing the skin of a patient, the carrier movable from a first position to a second position;
wherein the at least one release element is configured such that relative movement between the actuator and shield causes the at least one release element to engage the carrier and align at least one tab provided on one of the carrier and shield with at least one slot formed in the other of the carrier and shield, enabling the carrier to move from the first position to the second position.

Abstract
The medical puncturing device includes an actuator, a shield, and a skin puncturing assembly. The actuator and shield are movable relative to one another. The skin puncturing assembly includes a carrier and a skin puncturing element. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the distal end of the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed to puncture the skin of a patient. The carrier is maintained in the retracted position by interference engagement between the carrier and shield. A drive spring is provided to move the carrier from the retracted to puncturing positions. A retraction spring is provided to return the carrier to a position wherein the shield encompasses the skin puncturing element.

11. A medical puncturing device, comprising:
-
an actuator; a shield, the shield and the actuator movably associated with each other; and a skin puncturing assembly disposed at least partially within the shield, the skin puncturing assembly comprising a carrier and a skin puncturing element mounted to the carrier, the carrier movable from a first position to a second position; wherein, when the carrier is in the first position, the shield has a shield interference surface engageable with a carrier interference surface of the carrier; and wherein the carrier is capable of rotation when a force is applied to the actuator, the rotation enables disengagement of the shield interference surface from the carrier interference surface, thereby causing the carrier to move from the first position to the second position.

15. A medical puncturing device, comprising:
-
an actuator having at least one release element extending therefrom; a shield having a proximal end and a distal end, the actuator and shield movably associated with each other; a skin puncturing assembly disposed at least partially within the shield, the skin puncturing assembly comprising a carrier and a skin puncturing element mounted to the carrier, a distal end of the skin puncturing element adapted for puncturing the skin of a patient, the carrier movable from a retracted position wherein the distal end of the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed from the distal end of the shield to puncture the skin of the patient; and a release plate associated with the shield proximal end; wherein the at least one release element is configured such that relative movement between the actuator and shield causes the at least one release element to rotate the release plate about a longitudinal axis of the medical puncturing device and align at least one tab provided on the carrier with the annular opening in the release plate, enabling the carrier to move from the retracted position to the puncturing position.

16. A method of assembling a medical puncturing device, comprising:
-
providing an actuator having an open proximal end and an open distal end; inserting a shield into the actuator proximal end, a distal end of the shield extending outward from the actuator distal end; inserting a skin puncturing assembly into the actuator proximal end, the skin puncturing assembly comprising a movable carrier and a skin puncturing element mounted to the carrier, the skin puncturing element having a distal end adapted for puncturing the skin of a patient; and wherein the skin puncturing assembly is inserted into the actuator proximal end such that; the shield has a shield interference surface engageable with a carrier interference surface of the carrier, when the carrier is in the a position; and the carrier is capable of rotation when a force is applied to the actuator, the rotation enables disengagement of the shield interference surface from the carrier interference surface, thereby causing the carrier to move from the first position to the second position.

17. A method of actuating a medical puncturing device comprising:
-
providing the medical puncturing device comprising an actuator, a shield, and a skin puncturing assembly disposed at least partially within the shield, the skin puncturing assembly comprising a movable carrier and a skin puncturing element mounted to the carrier, the skin puncturing element having a distal end adapted for puncturing the skin of a patient, and the actuator and shield movably associated with each other; and causing relative movement between the actuator and shield, such that the actuator engages the carrier and rotates the carrier from an interference engagement with the shield to a position allowing the skin puncturing assembly to move axially within the shield to a position exposing the distal end of the skin puncturing element for puncturing the skin of the patient.

18. A method of actuating a medical puncturing device comprising:
-
providing the medical puncturing device comprising an actuator, a shield, and a skin puncturing assembly disposed at least partially within the shield, the skin puncturing assembly comprising a movable carrier and a skin puncturing element mounted to the carrier, the skin puncturing element having a distal end adapted for puncturing the skin of a patient, and the actuator and shield movably associated with each other; and causing relative axial movement between the actuator and shield, such that the actuator rotates a release element associated with the carrier to a position allowing the carrier to move axially within the shield to a position exposing the distal end of the skin puncturing element for puncturing the skin of the patient.
