A degassing device, allowing efficient maintenance and including upper and lower rollers which advance a film-forming material in an advancement direction while vertically conveying the same, a plate heater arranged adjacently to the film-forming material moving back and forth between the rollers, and a chamber including an outer wall. The gas generator is inserted into the diffusor and has a positive-locking connection with the diffusor chamber inner wall for its fixation in the diffusor. The pleural drainage catheter system includes an inflatable membrane and a drainage catheter integrally coupled to the inflation membrane, the drainage catheter defining a drainage lumen through which fluid is drawn from the pleural cavity, and an inflation lumen coupled for flow of inflation fluid to and from an interior of the inflatable membrane. The identifying reference is stored in a memory caching system as a record of the interaction.
