摘要:
A retractable safety syringe may have a needle, a 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(中):
可伸缩安全注射器可以具有针,注射器主体,轴封和柱塞组件。 主体的近端部分和柱塞的活塞可以限定真空室。 柱塞组件可以包括联接到活塞的轴。 轴可以具有至少一个非接合部分和至少一个接合部分。 柱塞组件可在存储位置和工作位置之间移动。 在储存位置,很少或没有力通过非接合部分施加在轴封上。 在工作位置,接合部分与轴密封件密封接合以密封真空室。 如果可伸缩的安全注射器预填充,可缩小或消除可伸缩安全注射器的止动器移动。
