    摘要： A safety syringe for medical use is disclosed as having an injection-molded body with a tubular barrel having a finger flange projecting transversely from the barrel near a proximal end of the barrel and a cylindrical collar projecting rearwardly from the finger flange to the proximal end of the barrel. A plunger assembly includes a plunger handle end cap and an elastomeric plunger seal insertable into the barrel through a rearwardly facing opening in the cylindrical collar to slidably engage the cylindrical inside wall of the barrel. A cylindrical elastomeric bushing is frictionally engaged around an outside wall of the cylindrical collar, and a selectively removable plunger cap frictionally engages the cylindrical elastomeric bushing. A safety syringe may also include a needle safety device.

    摘要： 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 The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

    摘要翻译： 本发明包括主体，枢转地连接到主体的致动器，以及可伸缩针，其适于提供可附接到该装置的患者与集液管（通常为采血管）之间的流体连通。 主体装置的显着特征是设置在致动器内部的缩回空腔，其可手动定位以在取出采血管之后接收针回缩组件的一部分。 通过按压致动器的向前延伸的端部相对于主体来启动缩回，从而使保持器夹子释放针保持器，之后针保持器和针的一部分通过压缩的膨胀被推入到缩回空腔中 弹簧。 因此，针从患者中撤出并进入外壳中，减少了意外针刺的可能性并防止了装置的再次使用。

    摘要： 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.

    摘要： A cap operated retractable medical device has an outer body with a hingedly connected outer cap which moves between an open and a closed position. The device is used as a blood sampler with a conventional collection tube normally used in such devices. A movable member is entirely enclosed within the outer body. A sliding interference or friction fit holds a retraction body within the mouth of the movable member and also holds the front end of the movable member within the outer body positioned within the retraction body adjacent a stop. A double ended needle is installed in the retraction body. Camming protrusions on the cap engage the back of the movable member to move it forward as the cap is closed thereby triggering retraction of the retraction body and its double ended needle entirely within the outer body. Once the cap is closed with the double ended needle safely inside, the device can be safely handled. The device is compact. It can be as short as the needles it will safely contain.
