Surgical sterilizing container and surgical fluid extraction device
A surgical sterilizing container is provided, having a bottom and a container wall. A through-opening is formed on the sterilizing container for the exchange of media. A valve device having an outlet valve is provided for opening and closing the through-opening. In order to remove fluid which has formed in the container interior while reducing the risk of germs penetrating into the container interior, the through-opening is formed in the container wall at a distance from the bottom, and the sterilizing container has a fluid lifting device for providing a fluid connection from the bottom to the outlet valve and for lifting fluid from the bottom to the outlet valve. A surgical fluid extraction device is also provided for use with a surgical sterilizing container having a container wall and a bottom.

9. Sterilizing container in accordance with claim 1 , wherein the channel outlet opening is directed at an upward flow side of the outlet valve.
10. Sterilizing container in accordance with claim 1 , wherein:
the fluid lifting device comprises an injector for lifting fluid through the fluid channel, and
the injector comprises an injector inlet opening and an injector outlet opening, via which a flow connection is provided from a container interior defined by the sterilizing container to the outlet valve, and also an injector suction opening arranged in a direction of flow between the injector inlet opening and the injector outlet opening and formed by the fluid channel.
11. Sterilizing container in accordance with claim 10 , wherein the injector is integrated in the fluid channel, the injector outlet opening being formed by the channel outlet opening and/or the injector inlet opening being formed in one of the first channel wall, the second channel wall, or a further channel wall of the fluid channel.
12. Sterilizing container in accordance with claim 1 , wherein the fluid channel has a cross-sectional constriction.
13. Sterilizing container in accordance with claim 12 , wherein in relation to a direction of flow of the fluid flowing from the bottom to the outlet valve, an inlet opening, via which a flow connection is provided from a container interior defined by the sterilizing container to the outlet valve, is formed upstream of the cross-sectional constriction in the fluid channel.
14. Sterilizing container in accordance with claim 1 , wherein the fluid channel comprises a first channel section aligned in a direction facing away from the bottom, and, in relation to a direction of flow of the fluid flowing from the bottom to the outlet valve, downstream of the first channel section, a second channel section which includes an angle with the first channel section.
15. Sterilizing container in accordance with claim 14 , wherein the first channel section is aligned at right angles or essentially at right angles to a set-down plane defined by the sterilizing container.
16. Sterilizing container in accordance with claim 14 , wherein the second channel section has an inclination relative to a set-down plane defined by the sterilizing container.
17. Sterilizing container in accordance with claim 1 , wherein the valve holder is detachably fixed to the container wall.
