Abstract
Abstract A sampling device for the collection of fluids for examination thereof defines plural surface expanses respectively differing in capacity for sorption of the fluid whereby fluid incident on the member may be conducted to a selected one of the surface expanses adapted to conduct the fluid substantially unidirectionally therethrough. A fluid container is associated with the latter sampling device surface expanse and may include an indicator to detect the components of contained fluid. The sampling device may be used in combination with a diaper to perform urine analysis.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
154 words
In combination with wearing apparel, for sampling body fluid issuing from a subject: means carried by said apparel for controlling the rate of flow of said body fluid including valve means having a surface expanse for conducting a predetermined volume of fluid therethrough at one rate and thereby rendered substantially non-conducting to fluid flow for another rate; sheet member means having a surface expanse for fluid disposition in an area of issuance of said body fluid and continuous with said valve means surface expanse, said sheet member means surface expanse including means for conducting fluid thereacross to a lesser extent than said valve means surface expanse, so that fluid incident on said sheet member means surface expanse is conducted to and through said valve means surface expanse; container means for containing fluid conducted through said valve means surface expanse; and means for fixedly supporting said valve means in fluid-issuing relation to said container means.
Claim 2
Dependent Claim
