VALVE DEVICE WITH ELASTICALLY PRETENSIONED CLOSURE ELEMENT FOR A MEDICAL SYSTEM

摘要

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) ranged 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 a 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 a 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 a valve device is provided which allows for an optimized integration into a medical device such as an infusion line or an infusion pump.

1. A valve device for a medical system, comprising:
a valve housing, an inlet port arranged on the valve housing, an outlet port arranged on the valve housing, a flow duct extending through the valve housing connecting the inlet port and the outlet port to allow for a fluid flow through the valve housing between the inlet port and the outlet port, and a closure element arranged on the valve housing for selectively opening and closing the flow duct.characterized inthat the closure element is displaceable along a displacement direction relative to the valve housing between a closed position in which the flow duct is closed for preventing a fluid flow from the inlet port to the outlet port and an opened position in which the flow duct is opened for allowing a fluid flow from the inlet port to the outlet port, wherein the closure element is elastically pretensioned towards the closed position.
