Abstract
Abstract A container for the drainage of body fluids such as urine has a partition defining and separating inlet and storage chambers for measuring and then storing the fluid, with the partition being open at its upper part to provide an interconnecting passage between the chambers. An inlet tube extends downward, slightly into the inlet chamber where its discharge end terminates with a one-way valve which is spaced below the chamber''s upper surface and generally above the passage for preventing backflow of fluid and bacteria. Fluid draining through the inlet tube drips first into the inlet chamber which is calibrated for accurate measurements, and can later be transferred to the storage chamber via the passage.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A body fluid drainage apparatus comprising: a. a storage chamber; b. a sampling chamber mounted on the storage chamber; c. common partition means separating said chambers from each other; d. inlet means extending through an upper portion of the sampling chamber and outlet means projecting from a lower portion thereof; e. passage means between the chambers for establishing fluid communication therebetween, said passage means including an opening provided in said partition means; and f. said inlet means including an inlet tube having a terminal end portion located above the bottom edge of said passage means and below the top edge thereof for discharging body fluid into said sampling chamber; whereby at least a sample portion of body fluid may be withdrawn from said sampling chamber via the outlet means thereof and any residual portion of body fluid may be transferred between the chambers via said passage means upon movement of said body fluid over the bottom edge of said passage means.
Claim 2
Dependent Claim
161 words
A body fluid drainage apparatus comprising: a. a storage chamber; b. a sampling chamber mounted on the storage chamber; c. common partition means separating said chambers from each other; d. inlet means extending through an upper portion of the sampling chamber and outlet means projecting from a lower portion thereof; e. passage means between the chambers for establishing fluid communication therebetween, said passage means including an opening provided in said partition means; and f. said inlet means including an inlet tube having a terminal end portion located above the bottom edge of said passage means and below the top edge thereof for discharging body fluid into said sampling chamber; whereby at least a sample portion of body fluid may be withdrawn from said sampling chamber via the outlet means thereof and any residual portion of body fluid may be transferred between the chambers via said passage means upon movement of said body fluid over the bottom edge of said passage means.
Claim 3
Dependent Claim
32 words
The body fluid drainage apparatus as recited in claim 10, further including one-way valve means on said inlet means for permitting unidirectional fluid flow from the inlet tube to the sampling chamber.
Claim 4
Dependent Claim
22 words
The body fluid drainage apparatus as recited in claim 1, wherein said passage means extends between the upper portions of said chambers.
Claim 5
Dependent Claim
41 words
The body fluid drainage apparatus as recited in claim 1, wherein the lower portion of said sampling chamber has smaller cross-sectional dimensions than that of the upper portion, and fluid volume indicia provided on the lower portion of the sampling chamber.
Claim 6
Dependent Claim
42 words
The body fluid drainage apparatus as recited in claim 1, further comprising nonwetting filter means secured to the storage chamber for permitting passage of air and other gas from within said chamber to the atmosphere while barring passage of liquid and bacteria.
