    • 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.
    • 可伸缩的安全注射器可以具有针,针保持器,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。

    • A selective nerve stimulation patch includes a substrate having a top surface and a bottom surface, integrated components overlying the top surface of the substrate and being electrically interconnected with one another for generating at least one nerve stimulating signal, electrodes integrated into the substrate and exposed at the bottom surface thereof for applying the at least one nerve stimulating signal to a target nerve, a waterproof, breathable cover overlying the substrate and the integrated components, and a support flange surrounding the substrate and coupling the cover and the substrate together. The support flange has a top surface that slopes downwardly toward an outer perimeter thereof, and at least a portion of the cover conforms to the sloping top surface of the support flange. In one embodiment, the patch generates a high frequency waveform with properties such as amplitude, frequency and the like chosen so as to overcome tissue impedance and the stimulation threshold of the target nerve. The modulated waveform is the waveform obtained by modulating the carrier waveform by a pulse envelope.
    • 选择性神经刺激贴片包括具有顶表面和底表面的基底,整合的元件覆盖在基底的顶表面上并且彼此电互连以产生至少一种神经刺激信号,集成到基底中并暴露于 其底表面用于将至少一个神经刺激信号施加到目标神经,覆盖在基底和集成部件上的防水透气盖,以及围绕基底并将盖和基底连接在一起的支撑凸缘。 支撑凸缘具有朝向其外周向下倾斜的顶表面,并且盖的至少一部分符合支撑凸缘的倾斜顶表面。 在一个实施例中,贴片产生具有所选择的诸如振幅,频率等特性的高频波形,以便克服组织阻抗和目标神经的刺激阈值。 调制波形是通过用脉冲包络调制载波波形而获得的波形。

    • A retractable safety syringe may comprise a needle, needle holder, syringe body, and a plunger. A proximal portion of the body and a piston of the plunger may define a variable vacuum compartment. A through hole pneumatically connecting ambient air and the variable vacuum compartment may be formed through a thumb platform and rigid shaft of the plunger for allowing air to escape out of the variable vacuum compartment when a piston of the plunger is traversed toward the retracted position and allow air to be introduced into the variable vacuum compartment when the piston is traversed toward the engaged position. A retraction force may be created by the variable vacuum compartment by covering an entrance of the through hole and traversing the piston to the engaged position. At the engaged position, the piston may engage the needle holder and the retraction force may retract the piston, needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.
    • 可伸缩的安全注射器可以包括针,针保持器,注射器主体和柱塞。 主体的近端部分和柱塞的活塞可以限定可变的真空室。 气动连接环境空气和可变真空隔室的通孔可以通过拇指平台和柱塞的刚性轴形成,用于当柱塞的活塞朝向缩回位置移动时允许空气从可变真空室中逸出,并允许 当活塞朝向接合位置移动时,被引入可变真空室的空气。 通过覆盖通孔的入口并将活塞穿过接合位置,可以通过可变真空隔室产生回缩力。 在接合位置,活塞可以接合针保持器,并且缩回力可以将活塞,针保持器和针缩回到注射器体中,以防止意外的针刺和针重复使用。
