Benefits of technology

The present invention is a seal cap assembly for use with a biological specimen container. The cap includes an integral ampoule, or vessel, that holds a pre-filled agent, such as a diluent, reagent, preservative, buffer solution, or the like, which is mixed with the specimen when the cap assembly is attached to the specimen container. The seal cap assembly allows for stabilization, storage, and transport of biological fluid samples. The cap assembly provides a safe, convenient, and inexpensive way to seal and stabilize biological specimens.

Problems solved by technology

Saliva, due to its chemical nature, is not adequately stable for use in some tests with some time delays.

Embodiment Construction

[0029]FIG. 1 shows one embodiment of an ampoule cap assembly 101 of the present invention. Ampoule cap assembly 101 can removably attach to a specimen tube 103 by way of external threads 105, said threads in particular embodiments may be internally oriented. Ampoule cap assembly 101 has corresponding internal threads, as well as other suitable mating features to attach ampoule cap assembly 101 to specimen tube 103. Specimen tube 103 will have been filled with a suitable volume of a biological sample fluid that needs chemical conditioning prior to storage, transport, or testing.

[0030]FIG. 2 shows the constituent components of an embodiment of ampoule cap assembly 101, starting with an ampoule cap housing 201. The constituent components and their functions and characteristics are described in greater detail later in this disclosure. A pre-filled agent 203 is loaded into the ampoule cap housing 201 through vessel opening 205. Pre-filled agent 203 is captured and sealed within ampoule c...

Abstract

A seal cap assembly for use with a biological specimen container, the cap assembly including an integral ampoule that holds a pre-filled agent. A piercer is movably disposed in the cap assembly to pierce into the ampoule. When the cap assembly is attached to a biological specimen container, the ampoule is pierced, the pre-filled agent in the ampoule is mixed with the specimen, and the seal cap assembly seals the biological specimen container. The seal cap assembly, together with a biological specimen container, permits stabilization, storage, and transport of biological fluid samples.

Description

RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Patent Application No. 61 / 548,473, filed Oct. 18, 2011, which application is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to biological specimen containers. More particularly, the present invention relates to containers used for collecting, storing, and transporting biological specimens to be used in assays, and more particularly to containers that chemically enhance the biological specimen.BACKGROUND[0003]Bodily fluids are collected for various reasons, including diagnosing illness, simple therapeutic removal, determining pregnancy, confirming or establishing levels of therapeutic agents, determining drug abuse, and profiling DNA composition. Blood, urine, and saliva are among the commonly collected bodily fluids for some or all of these purposes.[0004]A variety of methods are used to collect bodily fluids, depending on the...
