An aspirator for withdrawal of secretions from wounds has an evacuated vessel wherein the subatmospheric pressure prior to admission of secretions into its interior is maintained at a level of between about 0.8 and 1 bar. The vessel carries indicia denoting (e.g., in percent or in milliliters) the known-in-advance maximum quantity if secretions which can be sucked into the vessel by way of a cannula as well as lesser quantities which accumulate in the vessel while the pressure rises above the predetermined level as a result of admission of secretions.
