摘要： Negative pressure to accelerate flashback is formed by selective deformation of an elastomeric bladder. The bladder and a next adjacent cam means are enclosed in a housing, penetrated by a slide or roller engaging the cam surface. As the slide or roller moves along the cam surface, the bladder is selectively deformed first to close, then to evacuate distally and then to reopen at a negative differential pressure.
摘要翻译：通过弹性体膀胱的选择性变形形成加速闪回的负压。气囊和下一个相邻的凸轮装置封闭在由与凸轮表面接合的滑动件或滚子穿透的壳体中。当滑块或滚子沿着凸轮表面移动时，气囊首先被选择性地变形以关闭，然后向远侧排空，然后在负压差下重新打开。

摘要： A pair of compressible, hinged opposing arms enclose a bladder chamber, which in turn is coupled to the catheter. As the arms are compressed together, successive pivot fulcra close, in turn first pinching and closing, and then opening the bladder to create negative differential pressure against the catheter, and promoting flashback.

摘要： A small micron filter unit comprising a main body connector unit, a single structure filter element, and an adapter unit for complementary engagement with the connector and for receiving and holding the single filter element. Preferably, the adapter unit is of soft material, such as flexible PVC, which allows the adapter unit to expand and receive a ring with ridge of the single filter element within a recess thereof. The ridge on the external circumference of the filter element ring forms a resilient indent in the flexible PVC material of the adapter. The compressive force exerted by the adapter around the filter ring functions to securely retain it in place and also forms a fluid and air axial seal. After assembly of the adapter unit within the connector body unit, an overall leakproof component filter device is formed. For further assurance of leakproofness, a plastic solvent such as THF can be applied between the adapter and connector units externally at the junction thereof for forming a permanently bonded component filter device.
摘要翻译：一种小微米过滤器单元，包括主体连接器单元，单个结构的过滤元件和用于与连接器互补接合并用于接收和保持单个过滤器元件的适配器单元。优选地，适配器单元是软质材料，例如柔性PVC，其允许适配器单元在其凹部内扩张和接收具有单个过滤器元件的脊的环。过滤元件环的外圆周上的脊在适配器的柔性PVC材料中形成弹性凹口。适配器围绕过滤器环施加的压缩力用于将其牢固地保持在适当位置并且还形成流体和空气轴向密封。在连接器主体单元内组装适配器单元之后，形成整体的防漏部件过滤装置。为了进一步确保防漏性，可以在适配器和连接器单元之间的塑料溶剂（例如THF）的连接处将其施加到外部，以形成永久粘合的部件过滤装置。
