Flashback device for catheters |
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.
