Abstract: A pressure activated two-way slit valve assembly is designed to be used in combination with, but not limited to, a high flow rate catheter to prevent accidental ingestion of air or loss of blood if the closure cap comes off during non-use of the catheter. In addition, the potential for occlusion of the esthete due to blood clots in the catheter and catheter related infection is substantially reduced. The pressure activated two-way slit valve assembly includes a first end, a second end, a wall defining a dumbbell shaped channel, and a flexible, this disk having a slit and positioned within the pressure activated two-way slit valve assembly to reside within the dumbbell shaped channel. The slit and the dumbbell shaped channel are sized to enable the slit to deform in response to a predetermined pressure differential across the slit to allow fluid to pass therethrough.

In addition, the potential for occlusion of the catheter due to blood clots in the catheter and catheter related infection is substantially reduced.

Abstract translation: 压力致动双向狭缝阀组件被设计成与高流量导管组合使用，以防止意外摄取空气或血液丢失，如果在不使用过滤器的情况下封闭帽脱落 导管。 此外，由于导管中的血块和导管相关感染引起的导管堵塞的可能性大大降低。 压力激活的双向狭缝阀组件包括第一端，第二端，限定哑铃形通道的壁和具有狭缝并且定位在压力激活的双向狭缝阀组件内的柔性薄盘，以位于 哑铃形通道。 狭缝和哑铃形通道的尺寸设定成能够使缝隙响应于跨缝隙的预定压力差而变形，以允许流体通过。
