    摘要： A device for determining the depth of an incision from the epidermal layer to a puncture in a blood vessel in which the device includes an elongated member which has a lumen extending from a distal end to a proximal end. The distal end of the elongated member is configured to locate the blood vessel. After the device locates the blood vessel, a depth indicator is positioned to mark the depth of the blood vessel. In one embodiment, the elongated member includes a tapering interior surface which can receive a portion of the blood vessel. An extending control member may extend from the device at the distal end wherein the extending control member enters the blood vessel before the device locates the vessel. Fluid from the blood vessel enters the extending member through a vent hole and exits through an opening at the proximal end of the device, thereby providing a user with visual feedback that the device is moving in the desired direction toward the blood vessel.

    摘要： A device, system and method for improving delivery of hemostatic material, in which the device includes a vent cap body capable of removably engaging a cannula. The vent cap has a passage extending through the vent cap body from the cannula to an exterior of the vent cap body where a restricter for restricting the flow of fluid from the cannula to the exterior. In one embodiment, the vent cap has a valve which has an opened and closed position. In the closed position, the valve is designed to provide a back pressure or resistence. When a certain force is applied against the valve, the valve moves from the closed position to the opened position, where a gas or fluid may pass through the vent cap. The vent cap is designed to help maintain the continuity of the hemostatic material during delivery of the material from the adaptor to the trial staging chamber.

    摘要翻译： 一种用于改善止血材料递送的装置，系统和方法，其中所述装置包括能够可移除地接合插管的通气盖体。 通气盖具有一个通道，该通道从插管延伸穿过通气盖本体到通气盖体的外部，其中用于限制流体从套管流到外部的限制器。 在一个实施例中，通气盖具有具有打开和关闭位置的阀。 在关闭位置，阀被设计成提供背压或抵抗力。 当对阀门施加一定的力时，阀门从关闭位置移动到打开位置，气体或流体可以通过通气盖。 通气盖被设计成有助于在将材料从适配器递送到试验分级室时保持止血材料的连续性。
