摘要： A heart assist system having an implantable pump conveying blood between two vascular locations and an extracorporeal system providing power and control signals to the pump. The system also includes a communication link having an implantable portion coupled to the implantable pump, an extracorporeal portion coupled to the extracorporeal system and an isolation portion between the implantable portion and the extracorporeal portion that minimizes the transmission of movement and forces from the extracorporeal portion to the implantable portion.

摘要： A retractable safety syringe may have a needle, needle holder, syringe body, a shaft seal, and a plunger assembly. A proximal portion of the body and a piston of the plunger may define a vacuum chamber. The plunger assembly may comprise a shaft coupled to a piston. The shaft may have at least one non-engaging portion and at least one engaging portion. The plunger assembly is movable between a storage position and working positions. In the storage position, little or no force is exerted on the shaft seal by the non-engaging portion. In the working positions, the engaging portion is in sealing engagement with the shaft seal to seal the vacuum chamber. Stopper movement of the retractable safety syringe may be reduced or eliminated if the retractable safety syringe is prefilled.

摘要： A retractable safety syringe may have a needle, needle holder, syringe body, and a plunger assembly. A proximal portion of the body and a piston of the plunger may define a vacuum chamber. The plunger assembly may comprise a distal piston and a proximal piston, with an intermediate chamber disposed between the two plungers. A vent through the syringe body pneumatically connects ambient air and the intermediate chamber allowing air to escape out of the intermediate chamber when a plunger assembly traversed toward the engaged position and allow air to be introduced into the intermediate chamber. A retraction force may be created by the vacuum chamber by traversing the plunger assembly to the engaged position. At the engaged position, the distal piston may engage the needle holder and the retraction force may retract the needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.

摘要： A retractable needle safety syringe is provided having a braking mechanism. The braking mechanism may be disposed at a proximal portion of a syringe body of the syringe. The braking mechanism may comprise a brake member which is traversable between a braking position and a released position. At the braking position, the brake member frictionally engages an outer surface of the shaft of a plunger of the syringe. The frictional engagement counterbalances a retraction force that urges a piston of the syringe toward a retracted position. When the brake member is traversed to the released position, the brake member does not press against the outer surface of the shaft. As such, the retraction force may traverse the piston toward the retracted position and traverse a needle and needle holder into the body of the syringe.
摘要翻译：提供具有制动机构的伸缩针安全注射器。制动机构可以设置在注射器的注射器主体的近端部分。制动机构可以包括可在制动位置和释放位置之间移动的制动构件。在制动位置，制动部件与注射器的柱塞的轴的外表面摩擦接合。摩擦接合抵消了将注射器的活塞推向缩回位置的回缩力。当制动构件横穿到释放位置时，制动构件不会压靠轴的外表面。因此，缩回力可以朝向缩回位置移动活塞，并且将针和针保持器穿过注射器的主体。

摘要： 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.

The braking mechanism may comprise a brake member which is traversable between a braking position and a released position. At the braking position, fingers of the brake member frictionally engage an outer surface of the shaft of a plunger of the syringe. The frictional engagement counterbalances a retraction force that urges a piston of the syringe toward a retracted position. When the brake members are traversed to the released position, the fingers do not press against the outer surface of the shaft. As such, the retraction force may traverse the piston toward the retracted position and traverse a needle and needle holder into the body of the syringe.
