A suction bottle for evacuating secretions from wounds is disclosed. The bottle includes a vacuum indicator arrangement located over a pressure opening 6 in the bottle, a sealing tube 7, a return spring 9, and a graduated scale bearer 10. In response to changes in pressure within the bottle, abutment 8 is caused to travel within graduated scale bearer 10, thus indicating the pressure within the bottle. |
