    • A retractable needle catheter insertion device is provided with a cannula and a needle positioned within the cannula to assist with insertion of the cannula. After insertion of the cannula into a patient, the needle can retract into a protective sleeve that contains the needle in order to reduce the chance that a medical practitioner will be inadvertently stuck by a used needle. The needle is carried by a needle support that is slidably disposed within the sleeve. A spring biases the needle support and needle toward a retracted position, and the device also includes an activation hub that works in conjunction with the needle support to control retraction of the needle. The retraction may be activated manually by the medical practitioner or may be activated automatically. A modular system and method of manufacturing is also provided in which catheters having either manually or automatic retraction can be manufactured using common parts.
    • 可伸缩针导管插入装置设置有插管和定位在插管内的针以帮助套管的插入。 在将插管插入患者体内之后,针可缩回到包含针的保护套中,以减少医生将被用过的针不经意地卡住的机会。 针由可滑动地设置在套筒内的针支撑件承载。 弹簧将针支撑件和针头朝向缩回位置偏置,并且该装置还包括与针支撑件一起工作以控制针的缩回的激活毂。 缩回可以由医生手动激活或者可以被自动激活。 还提供了一种模块化系统和制造方法,其中可以使用手动或自动缩回的导管使用公共部件来制造。

    • A round counter for a firearm is provided that includes a display that provides the user with information regarding the number of rounds remaining in the magazine of the firearm. The magazine includes a round follower and a wiper extending from the follower. The wiper contacts a variable resistance sensor, such as a linear potentiometer, that is attached to a sidewall of the magazine. As the round follower and wiper move up and down within the magazine, the wiper contacts the sensor at different positions. The position of the wiper relative to the sensor corresponds to a specific linear distance indicative of the number of rounds remaining in the magazine. Information regarding this position, and consequently the number of remaining rounds is transmitted to the display.
    • 提供了用于枪支的圆形计数器,其包括显示器,该显示器向用户提供关于枪械的弹匣中剩余的回合数量的信息。 该杂志包括一个圆形随从器和从随动器延伸的雨刷器。 雨刮器接触连接到仓匣侧壁的可变电阻传感器,例如线性电位计。 随着圆形从动件和雨刮器在刀库内上下移动,擦拭器会在不同位置与传感器接触。 擦拭器相对于传感器的位置对应于特定的线性距离,该线性距离指示存储盒中剩余的回合数。 关于这个位置的信息以及因此剩余轮次的数量被传送到显示器。
