    • Disclosed herein are methods and devices of obtaining plethysmograph readings and utilizing plethysomography to identify when pilots are about to experience GLOC. Furthermore, in other embodiments, the invention pertains to methods and devices designed to warn a pilot that he/she is about to enter GLOC and/or automatically averting catastrophic damage or injuries by directing a plane being piloted to take predetermined corrective actions. Specifically disclosed is a system embodiment for assisting in the prevention of gravity induced loss of consciousness. The system comprises at least one pulse oximeter probe 10 configured for securing to a central source site of a pilot and to generate signals indicative of blood flow at said central source site, an analyzer unit 58 communicatingly connected to said at least one pulse oximeter probe 10, said analyzer unit comprising at least one processing module 56 configured to determine whether said blood flow is approaching a predefined level, and an aircraft computer 51 communicatingly connected to said analyzer unit 58, said aircraft computer 51 comprising at least one processing module 59 configured to effect a predetermined reaction responsive to said blood flow falling below a predetermined level.
    • 本文公开了获取体积描记器读数并利用体积描记术来鉴定飞行员即将经历GLOC的方法和装置。 此外,在其他实施例中,本发明涉及用于警告飞行员他/她将要进入GLOC的方法和装置,和/或通过引导被引导的飞机采取预定的纠正措施来自动避免灾难性的伤害或伤害。 具体公开的是用于辅助预防重力引起的意识丧失的系统实施例。 该系统包括至少一个脉冲血氧计探针10,其被配置用于固定到导频的中心源站点,并产生指示所述中心源站点处的血流的信号;分析器单元58,其通信地连接到所述至少一个脉搏血氧计探针10 所述分析器单元包括被配置为确定所述血流是否接近预定水平的至少一个处理模块56以及与所述分析器单元58通信连接的飞行器计算机51,所述飞行器计算机51包括至少一个处理模块59, 响应于所述血流低于预定水平而影响预定的反应。

    • An intraosseous needle having a threaded shaft with a passageway extending substantially therethrough, a solid and pointed tip at one end thereof, the tip having a plurality of cutting edges which facilitate boring through a bone. The shaft also includes two side ports in communication with the passageway to allow fluids to pass through the needle into the interior of the Done after successful insertion thereof. There is a hub at the opposite end of the shaft, whereby the needle is adapted to couple with an appropriate gripping device. A handle is provided in the shape of a ball knob and is adapted to telescopically and grippingly receive the hub of the needle. The hub and handle are both equipped with mutually engaging torque-transmitting surfaces. Additionally, the threads of the intraosseous needle may optionally be tapered so that at least one thread at the proximal end of the threaded shaft has a greater major (and/or minor) diameter than at least one thread located at the distal end of the threaded shaft. As the needle is inserted, the tapering of the threads provides a tighter fit between the bone and the needle to prevent needle wobble and fluid leakage.
    • 具有螺纹轴的骨内针,其具有基本上穿过其延伸的通道,在其一端具有固体和尖端,所述尖端具有多个切削刃,其有利于穿过骨。 轴还包括与通道连通的两个侧端口,以允许流体在其成功插入之后通过针进入Done的内部。 在轴的相对端具有毂,由此针适于与适当的夹持装置联接。 手柄设置成球形旋钮的形状,并且适于伸缩地并且夹紧地容纳针的轮毂。 轮毂和手柄均配有相互接合的扭矩传递表面。 此外,骨内针的螺纹可以可选地是锥形的,使得在螺纹轴的近端处的至少一个螺纹具有比位于螺纹的远端处的至少一个螺纹的更大的主要(和/或次要)直径 轴。 当针被插入时,螺纹的锥形使得骨头和针之间的紧密配合以防止针头摆动和流体泄漏。
