摘要:
A collection device and a method for collecting a biological sample, particularly whole blood, includes a separating member to separate the whole blood into its components, and at least reagent positioned to selectively interact with a component of the separated sample. The reagent is able to selectively interact with the plasma/serum, and is prevented from contacting or interacting with the whole blood.

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.

The medical puncturing device includes a housing (12), a shield (13), and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. 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 skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.

摘要:
A suture lock fastening device to cinch a suture in a suture lock, cut the suture end, and deploy the suture lock in response to a single movement of a user. The fastening device includes a fastening head with a retainer that is configured to hold a suture lock in the fastening head. To release the suture lock from the fastening head, the retainer is irreversibly deformed. The fastening device may include an axially movable cutter with a cutting edge to sever the ends of the suture close to the suture lock. A threading device may be preloaded into the fastening device to facilitate threading the suture through the fastening device.

摘要:
A method of using a needle assembly having a telescoping shield that extends from a starting retracted position to a venipuncture partially extended position during the standard sequence of operation of drawing a blood sample with an evacuated blood collection tube and needle holder. After the procedure is complete and the needle is removed from the patient the shield continues to extend to a fully extended and locked position over the distal end of the needle rendering the needle safe and preventing needle stick injuries.

Locking and releasing apparatus for operating a medical device includes a handle and a lever member coupled to the handle for grasping engagement by an operator. The lever member is moveable in opposite directions relative to the handle. A locking and release mechanism operably connects the lever member to a force transmitting member for operating the medical device at a location distant from the handle. The locking and release mechanism locks movement of the force transmitting member in one direction after movement of the lever member in a locking direction. The locking and release mechanism releases movement of the force transmitting member in the one direction after opposite movement of the lever member in a releasing direction. The lever member operates the locking and release mechanism for releasing the movement of the force transmitting member in the one direction substantially upon changing movement of the lever member from the locking to the releasing direction.
摘要:
A needle assembly having a telescoping shield that extends over the distal end of the needle when released by an actuator that is triggered during a standard sequence of operation of a medical procedure. For example, the telescoping shield extends by a compression spring from a starting retracted position to a venipuncture partially extended position during the standard sequence of operation of drawing a blood sample with an evacuated blood collection tube and needle holder. After the procedure is complete and the needle is removed from the patient the shield continues to extend to a fully extended and locked position over the distal end of the needle rendering the needle safe and preventing needle stick injuries.
