1. A method for creating a capillary flow relationship among three pieces of bibulous material which prior to actuation are in a non-capillary flow relationship to each other which comprises:
- (a) providing a device which comprises (i) two pieces of bibulous material each in a non-capillary flow relationship to the other, and (ii) a distortable member having affixed thereto a third piece of bibulous material, said distortable member being disposed with respect to said two pieces of bibulous material such that distortion of said distortable member brings said third piece of bibulous material into contact with said two pieces of bibulous material, and(b) distorting said distortable member by insertion thereof into a container having limited space resulting in constriction of said distortable member, which thereby results in contact of said pieces of bibulous material so as to achieve a capillary flow relationship among said pieces.

Abstract
Disclosed are assay apparatus, devices and methods that permit longitudinal capillary flow of liquid between two pieces of bibulous material which, prior to actuation, are in a non-capillary flow relationship to each other. In particular, the devices utilize a distortable member which when distorted, actuates the device by creating a capillary flow relationship between the two pieces of bibulous material. In an alternative embodiment the apparatus, devices, and methods include at least one additional piece of bibulous material.

6. A kit for conducting an assay comprising in packaged combination:
-
(a) a device which permits longitudinal capillary flow of a liquid through three pieces of bibulous material which prior to actuation are in a non-capillary flow relationship to each other, which device comprises; (i) two pieces of bibulous material each in a non-capillary flow relationship to the other and (ii) a distortable member having affixed thereto a third piece of bibulous material, said distortable member being disposed with respect to said two pieces of bibulous material such that distortion of said distortable member brings said third piece of bibulous material into contact with said two pieces of bibulous material, (b) a container adapted for insertion of said device therein, wherein said container is adapted to actuate said device, when said device is inserted into said container, by distorting said distortable member thereby bringing said third piece of bibulous material into contact with said two pieces of bibulous material and (c) separately packaged reagents for conducting an assay, said reagents comprising at least one member of a signal producing system. - View Dependent Claims (7)

8. A device that permits capillary flow of a liquid through three pieces of bibulous material which prior to actuation are in a non-capillary flow relationship to each other which comprises:
-
an element comprising (a) two pieces of bibulous material each in a non-capillary flow relationship to the other, and (b) a distortable member having affixed thereto a third piece of bibulous material and said two pieces of bibulous material, said distortable member being disposed with respect to said two pieces of bibulous material such that distortion of said distortable member brings said third piece of bibulous material into contact with said two pieces of bibulous material; and a container adapted for insertion of said element therein, wherein said container is adapted to actuate said device, when said element is inserted into said container, by distorting said distortable member thereby bringing said third piece of bibulous material into contact with said two pieces of bibulous material. - View Dependent Claims (9, 10, 11, 12)
