| 摘要 |
The present invention relates to a selector valve for use in medical technology, in particular for use with the parenteral or enteral administration of fluids, comprising a main housing (8) through which the fluid flows at least in some sections and an actuator accommodated in said housing that can be rotated about a central axis (6). The main housing comprises connecting points (1, 2, 3) for the inflow and outflow of the medium and forms an actuator receptacle (7), which comprises a pin (4) disposed concentrically to the central axis and a radially peripheral recess on the inside of the main housing, and the actuator comprises an operating element and a substantially hollow-cylindrical section, which accommodates the pin of the actuator receptacle at least in some sections, comprises at least one flow opening for the fluid connection of at least two connecting points, and at least one radially peripheral protrusion on the outer side of the cylindrical section, and wherein the pin of the actuator receptacle comprises at least one counter bearing for the actuator to form a sealing surface in the region of at least one connecting point. The invention is characterized in that the surface of the selector valve coming in contact with the fluid is produced at least in some sections from an antiseptic or antimicrobial material. |
