Presentation: Stopcock With A Swabbable Port Including Minimum Dead Space October 2004

Minimum Dead Space Swabbable Stopcock Current Design Current Design Concept A Concept A

Minimum Dead Space Swabbable Stopcock Current Design

Minimum Dead Space Swabbable Stopcock The problem with the current design: Flow Too big “dead space”, i.e. a volume not flushed by regular flow through the device Dead space Current Design

Minimum Dead Space Swabbable Stopcock 5 Concept A Flow Circumferential flow path Flow guide Dead Space No Dead Space Flow directions

Minimum Dead Space Swabbable Stopcock Alternative design Old design Comparing the current design with Concept A

Minimum Dead Space Swabbable Stopcock The different Flow positions Free flow, both ports open (routine) Patient side closed, pressure side open All ports in closed position Pressure side closed, patient side open Back to concept A
