Evacuated bottle draining secretions from wounds - is connected to non-evacuated, sterile container by pipe fitted with stop valve

摘要

Secretions are exhausted from a wound by a tube which is connected to an evacuted bottle (1). In order to vary the degree of vacuum in the bottle it is connected to a non-evacuated, sterile container (9, 10) by a tube (11) fitted with a stop valve. The sterile container may be formed as an integral part of the evacuated bottle, with a valve fitted between the two parts. Clamping clips may be used instead of stop valves. ADVANTAGE - Facility for reduced vacuum without sterility impairing.
