20080215009 | IV Catheter introducer with retractable needle - continuation - An IV catheter introducer having a retractable needle holder and a tubular plunger that are held by a detent structure in a preferred positional relationship prior to and during insertion of the catheter. Following insertion, the plunger is pushed past the detent structure, permitting a compressed spring to force the needle holder upwardly into the plunger. A vented end cap in the plunger permits rapid venting of air displaced during retraction of the needle holder. The needle holder includes a flash chamber that is easily viewable through a clear plastic housing. Wings are provided on the housing to facilitate one-handed operation of the device. A method for assembling the subject catheter introducer is also disclosed. | 09-04-2008 |
20080221517 | Fixed-Dose Syringe with Limited Aspiration - A syringe configured with a limited maximum usable capacity. The syringe of the invention desirably has a retractable needle to prevent reuse. In the preferred embodiment, a dose-limiting structure includes a stop-ring member on the head of the plunger that abuts a constriction in the housing when the plunger is moved away from the needle to prevent the further rearward movement of the plunger. Preferably, the syringe of the invention is configured such that a user is tactilely signaled when the plunger has reached a position corresponding to a nominal fixed-dose. If the user attempts to force the stop-ring member beyond the constriction, the plunger seal is stripped off or removed from the plunger head and the syringe rendered inoperable. The features of the invention can also be applied to a nonretracting syringe. | 09-11-2008 |
20080243075 | Medical Device with Retractable Needle - A tamperproof retractable non-reusable syringe has a one piece hollow outer body with a barrel for a slidable plunger, a transition zone and a smaller diameter nose portion. An elongated needle holder and spring combination is installable from the rear of the outer body, guided into the nose portion and held by cooperating inwardly and outwardly facing surfaces oriented in the direction of retraction at the most constricted part of the transition zone where the nose begins. The plunger has an opening with a dislodgable stopper for receiving parts of the retraction mechanism. The stopper and the head of the needle holder are of significantly reduced diameter from the injection fluid chamber to resist blowing out prematurely. In one embodiment the head of the needle holder is surrounded by a separable retainer member which is slidingly removed by contact with the tip of the plunger after the stopper is mostly or fully removed to avoid cumulation of force required for retraction after the injection. In a second embodiment the head of the needle holder is clamped and held by constricting forces imposed by stress on the outer body induced by interference fit. Release occurs by slight expansion on the barrel by contact of the plunger tip with a small internal ramp in the outer barrel. Both embodiments have a plunger cap configured to enter an opening in the outer body to provide an additional tamperproof feature. The retraction cavity is provided with venting structures to assure that all uninjected fluid is retained within the syringe body. | 10-02-2008 |

20120259243 | Blood Draw Device with Retractable Needle - The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device. | 10-11-2012 |
