If the valve was not present there would be pulsatile blood flow from the body through the sheath.

HYDRAULIC COUPLING ASSEMBLY COMPRISING TWO INTERCONNECTING MATING HALVES USED FOR FLUID TRANSFER PROVIDING A SEALING CONNECTION BETWEEN INTERCONNECTING FLUID CONDUITS, SUCH THAT MULTIPLE CONNECTORS CAN BE ARRANGED WITHIN A HYDRAULIC SYSTEM. WITHIN THE FLUID PASSAGEWAY, A CHECK VALVE ARRANGEMENT AUTOMATICALLY OPENS UPON ENGAGEMENT, BUT CLOSED ON DISENGAGEMENT TO PREVENT FLUID LOSS WHEN DISCONNECTED. COUPLINGS CAN BE FITTED WITH DIFFERENT TYPES OF POPPET (CHECK VALVE) TO PROVIDE VENTING OF INTERNAL PRESSURE IF REQUIRED.
