Abstract
A wound irrigation device designed for use with a standard syringe and suction trap comprises a shield (10) which incorporates an irrigation tube (12) and nozzle (14) to deliver fluid at high pressure to a wound. The shield protects the operator from splashback, and includes a suction tube (16) to scavenge effluent, thus preventing spillage back into the wound or onto the patient and environs. A portable lavage/suction unit (28) may be used with the irrigation shield to provide fluid under pressure for irrigation, or to provide anesthetic under higher pressure for wound infiltration.
