Abstract
A medical suction device is provided in which a constant force means is utilized to create substantially constant vacuum in a chamber of the suction device, as the device progressively fills with fluid being drawn thereinto from a catheter or the like. The fluid drawn into the chamber of the suction device is selectively dischargeable therefrom into a discardable receptacle that is attached through a drain valve to the chamber. Multiple, folded, discardable receptacles, each connected through a separate drain valve, are connected to the storage chamber of the suction device. The arrangement operates to effect isolation against transmittal of infection. The multiple discardable receptacles accommodate a high volume of discardable material, while the suction device apparatus is of low bulk and is provided with means to prevent exposing the suction chamber to atmosphere, and to atmosphere-borne contamination.
