Patent number: 6202898Abstract: With this device the fluid is located in a container which can be set under pressure, into which two cannulas of differing lengths may be inserted. A short cannula, via a gas conduit and a release valve, is connectable to a pressurised gas source in order to impinge the container above the fluid level with pressurised gas, whilst the other longer cannula is connectable to a fluid conduit leading to the instrument and protrudes into the fluid located in the container. The fluid flow to the instrument is interruptable with a blocking element and the pressurised gas supply to the container is interruptable with the release valve. Such a device may be simply constructed and used when, according to the invention, the cannulas, the blocking element and a control valve are grouped together into a constructional unit on which there is located one connection for the gas conduit and a further connection for the fluid conduit.Type: GrantFiled: April 15, 1999Date of Patent: March 20, 2001Assignee: Richard Wolf GmbHInventor: Guido Koch
