| 20110275991 | Retractable Safety Syringe - A retractable safety syringe may have a ferrule and needle which are selectively removeable from a distal end of a syringe body. In particular, the ferrule may have an annular flange. A wedge element may be frictionally engaged to the ferrule and a distal end of the syringe body. To retract the needle into the syringe body, a punch of a piston displaces the wedge element off of an annular flange of the ferrule. At about the same time, longitudinally offset tabs engage an annular flange and retract the needle into the syringe body via a retraction force created by a variable vacuum compartment or tension member. | 11-10-2011 |
| 20110264052 | Safety Needle Syringe Braking System - A braking mechanism for a retractable safety syringe is disclosed herein. In a first embodiment, the braking mechanism is disposed about the distal end of a piston. The braking mechanism may comprise a friction material about a post attached to a piston. The friction material is displaced from a seat to a landing when the piston is traversed to a fully extended position to disengage the braking mechanism. In a second embodiment, the braking mechanism is disposed at a proximal end of a syringe body. The braking mechanism has a friction member which engages an outer surface of a rigid shaft of a plunger. The friction member is selectively pivotable to disengage the braking mechanism. | 10-27-2011 |
| 20100324484 | Vacuum Actuated Small Volume Syringe - A retractable safety syringe is provided herein wherein an external vacuum compartment produces a retraction force which urges a piston of a plunger toward a retracted position. The retractable safety syringe may have a needle holder which is removably engageable to a distal portion of a syringe body. When the piston is traversed toward the engaged position, the external variable vacuum compartment produces a retraction force. When the piston is traversed to an engaged position, the piston engages the needle holder and disengages the needle holder from the syringe body. The medical professional may release a thumb pressure on a thumb platform of a plunger. At this point, the retraction force of the external variable vacuum compartment may traverse the piston along with the needle holder and needle toward the retracted position and into the syringe body. An internal variable vacuum compartment may also create a retraction force to assist retraction of the needle holder and needle into the syringe body. | 12-23-2010 |
