Abstract
A fluid delivery system has a container with an integrally attached sample cell. A selected fluid can be accumulated in the container. The sample cell can be filled with part of the fluid in the container and then isolated from the container by heat or dielectric sealing. The fluid in the sample cell can be brought into contact with selected test reagents. The test reagents can provide a visual indicia of the presence of selected characteristics in the fluid.
Claims31
A fluid delivery and test system comprising:
- a flexible, sealable container defining a volume for accumulating a quantity of a pre-selected fluid;
- and
- a fluid receiving specimen cell affixed to a selected region of said container, said specimen cell in fluid flow communication with said container and isolatable from said container while still affixed thereto such that the contents of said specimen cell can be selectively tested while said cell remains affixed to said container.
A medicinal liquid delivery and test system comprising:
- a flexible, sealable, plastic collection container defining a volume for accumulating a quantity of a pre-selected medicinal liquid;
- and
- a liquid receiving specimen cell affixed to a selected region of said container, said specimen cell in fluid flow communication with said container and isolatable from said container while still affixed thereto with the contents of said specimen cell testable with said cell affixed to said container.
A system as in claim 27 with one or more of said analysis cells displaying a predetermined color in response to the presence of a respective selected characteristic in the fluid sample subsequent to said frangible member having been broken.
A method of testing a fluid sample associated with a larger quantity of fluid such that the sample and the larger quantity are physically carried together, the steps of the method comprising:
- providing a sample volume for fluid to be tested affixed to a container with the sample volume in fluid flow communication with an internal volume of the container;
- filling, at least in part, the sample volume and the container volume with the selected fluid;
- blocking fluid flow communication between the sample volume and the container volume;
- and
- testing the fluid contents of the sample volume.
A fluid delivery and test system comprising:
- first means defining a fluid retaining volume;
- second means defining a fluid retaining volume, said first and said second means in fluid flow communication and permanently physically interconnected;
- means for blocking fluid flow between said defined volumes;
- and
- means, carried by said first volume defining means, for testing a fluid contained therein while said first and said second means are physically interconnected.
