Abstract The present invention comprises a vacuum-operated fluidcollection bottle and system including a serially-connected tandem system. Dual vacuum bosses for a representative bottle, one being valved, in multiple-boss covers may be used as respective automatic shut-off and tandem-fill means, with the non-applicable boss being releasably capped off. Two of the three conduit portions of the cover may be connected together through appropriate valving system so that either or both may be effective in supplying vacuum communication to the interior of the bottle at selected height levels. Valving means pre-determine maximum fluid height within the bottle, either automatically or by valve adjustment. A representative bottle may include fluid inlet and vacuum ports of differing level-dimension, to aid the lower vacuum port to close off or to conduct outwardly body-fluid while maintaining the inlet port above the bottle fluid level.
In combination, first and second fluid collection bottles each having a fluid inlet port, a free vacuum port, and a fluidlevel controlled, valved vacuum port; a fluid inlet conduit connected to said fluid inlet port of said first bottle; conduit means for coupling said free vacuum port of said first bottle to said fluid inlet port of said second bottle; vacuum pump means; and conduit means connecting said valved vacuum port of said second bottle to said vacuum pump means, said valved vacuum port of said first bottle being selectively closeable.
