Abstract
Abstract An operating room accessory for surgeons provides aseptic and closely controllable pressure wash for irrigating chest cavities, abdominal cavities, wounds and the like, in the form of a flexible-wall reservoir adapted for hanging from an I.V. support or other suitable support and having provision for hypodermic needle pressurization of the contents or administration of any medication, by insertion through a portion of the wall, and alternatively for pressure-cuff bulb pressurization; the unit includes an on-off clamp located for access by operating room assistants, and a flow control nozzle at the output for manipulation by the one operating.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
In a surgical wash system having a reservoir for hanging from a support such as an I.V. pole, flexible tubing for discharing fluid from the reservoir, means associated with the flexible tubing for controlling discharge of fluid from the reservoir including a nozzle for directing fluid discharged from the reservoir, the improvement comprising: the reservoir being a closed container having a flexible wall, and said means for controlling including micro-control means for varying the pressure within the closed container, said micro-control pressure varying means including penetrable valve structure in said flexible wall for admission of the needle of a hypodermic syringe for passage of fluid therethrough under urging of said a hypodermic syringe.
