Abstract
Abstract The present invention comprises a body fluid bottle preferably taking the form of a container and a cover interlocked therewith. Included are respective vacuum and body-fluid conduits or ports constructed for communication with interior of the container and for respective connection to a vacuum system and to appropriate means proximate the patient being supplied the same. Antisplash means may be provided. The body fluid conduit preferably extends into the container cavity and, in one form of the invention, includes means for preventing siphoning or back-flow of fluid stored in the container. Such means may comprise an apertured tube spaced from a body fluid conduit, for equalizing of gaseous pressure proximate the body fluid port with the remainder of the bottle interior, thereby avoiding dangers of back-flow or siphoning of contents of the bottle where gaseous pressure inside the container is raised above normal vacuum operating level. The container is constructed for insertion-stacking.
