ABSTRACT:
An infusion site for infusing fluids into a patient is disclosed. The infusion site has a housing which supports a pre-slit resealable septum which is held in radial compression in the housing. The septum is opened by the insertion of a cannula. The housing also accommodates a valve which is held in tension in the housing and is opened by the insertion of the cannula into the septum.
The valve is closed when the cannula is withdrawn. The septum and valve are linked by an elastic member which interacts with the cannula to open and close the valve.
