Abstract

A valve device (1) for a medical system comprises a valve housing (10), an inlet port (102) arranged on the valve housing (10), an outlet port (103) arranged on the valve housing (10), a flow duct (12) extending through the valve housing (10) connecting the inlet port (102) and the outlet port (103) to allow for a fluid flow (P) through the valve housing between the inlet port (102) and the outlet port (103), and a closure element (11) arranged on the valve housing (10) for selectively opening and closing the flow duct (12). Herein, the closure element (11) is displaceable along a displacement direction (A) relative to the valve housing (10) between a closed position in which the flow duct (12) is closed for preventing the fluid flow (P) from the inlet port (102) to the outlet port (103) and an opened position in which the flow duct (12) is opened for allowing the fluid flow (P) from the inlet port (102) to the outlet port (103), wherein the closure element (11) is elastically pretensioned towards the closed position. In this way the valve device is provided which allows for an optimized integration into a medical device such as an infusion line or an infusion pump.
