| Abstract: |
The present invention comprises a body fluid collection bottle construction wherein the container portion thereof is provided with fluid constraining means, this to provide a container area of reduced transverse cross-section such that an initial filling of the lower portion of the container, even as to introduction of small quantities of liquid, will result in a rapid rise in the fluid level. In such event, and with the employment of appropriate graduation indicia, small amounts of fluid initially introduced into the bottle may be very accurately measured. Above the lowermost, fluid constraining portion of the bottle construction, the introduction of progressively larger amounts of liquid will produce a reduced vertical rise in the fluid level of the upper portion of the bottle construction.

| Claim |
We claim:
1. A surgical fluid collection bottle for pediatric use and including, in combination, structure defining a fluid enclosure and comprising a container having a support base, a transparent side wall, and an upper lip margin, a cover constructed for releasable securement to said upper lip margin, said cover being so releasably secured to said upper lip margin, said cover including mutually spaced vacuum pump operated vacuum port means and fluid inlet port means depending beneath said cover within said container and communicating with the interior thereof, said container including a uniformly angulated non-horizontal uni-cavity-forming body-fluid partition spanning the cross-sectional interior of said container and disposed beneath both of said port means and above said support base, for increasing fluid-level displacement for a given deposit volume proximate said partition in a constricted lower volume area bounded by said partition and a peripheral sector of said side wall relative to that displacement occurring for an equivalent volume disposed in an upper volume area situated above said lower volume area and formed by said side wall above said sector, said structure also including mutually, vertically spaced graduation indicia disposed on said side wall of said container proximate said partition.
