Abstract
Abstract An apparatus for supplying aseptic fluids to a field of operation, as in surgery, especially bone surgery, includes a holder for the aseptic fluid which has elastically deformable walls, an outlet pipe which can be connected to the operating field, and a container surrounding the deformable holder to which a controlled supply of pressure fluid can be furnished to regulate the supply of fluid to the point of operation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
Apparatus for feeding aseptic fluids to a field of operation comprising a holder for aseptic fluids having elastically deformable walls, an outlet pipe connected to said holder for directing fluid to a field of operation, and means for applying pressure on the outside of such walls, said pressure applying means being adjustable to control the quantity of outflow from the holder, the means for applying pressure including a closed container enclosing the holder and means for supplying a compressible fluid under pressure to said container on the outside of the holder, means for controlling the supply of pressure medium to the container, said outlet pipe including an adjustable throttle valve for controlling the quantity of fluid flowing therethrough per unit of time, the outlet pipe containing a check valve means for permitting flow only in the direction away from the holder and preventing back flow in the outlet pipe, the holder being interchangeably arranged in the container.
