Definitions

  • the present invention is directed to a fluid specimen collecting and testing apparatus suitable for field or laboratory use. More particularly, the present invention is directed to an apparatus for collecting and testing biological fluids in a single apparatus while preserving the integrity of the originally collected specimen.
  • analyte e.g. drugs and/or disease
  • an animal or human i.e., urine, blood, sputum, pleural, cavity and peritoneal cavity fluids for analysis. Maintaining the integrity of the collected biological fluid specimens is vital to obtaining reliable test results and to preserving an uncontaminated sample for subsequent confirmatory testing. It is of utmost importance during the collection and handling of biological fluid specimens that the potential for specimen contamination be minimized or eliminated. It is also important to minimize the potential for specimen damage during the collection process and testing process.
  • the present invention involves an integrated fluid collection and testing apparatus that may be used with any type of fluid specimen, and is particularly useful for urine, blood and saliva specimens.
  • the apparatus collects a fluid specimen, isolates a predetermined portion of the specimen, and exposes only the isolated portion of the specimen to diagnostic or testing structures and/or reagents.
  • the isolated portion may be isolated as the fluid is collected in the apparatus, i.e., without any additional manipulation by testing personnel. The isolated portion is then independently tested in isolation from the collected fluid specimen.
  • the fluid specimen collecting and testing apparatus includes a collecting chamber for collecting the fluid specimen, an isolation chamber for isolating an aliquot of the fluid specimen for testing, and a test chamber or region for testing the specimen.
  • the collection chamber is never in fluid communication with or open to the test chamber.

  • the isolation chamber is in fluid communication with the collection chamber so that the aliquot can be readily isolated without complex manipulation by collection personnel.
  • a test chamber is provided for performing diagnostic testing on the aliquot.
  • the isolated portion of the fluid does not contact the remainder of the collected sample once the isolated portion comes in contact with contaminating structures or reagents.
  • the collected sample is maintained in a pristine or unadulterated state.
  • a totally closed (sealed) system is provided which prevents the fluid specimen from leaking to the outside environments.
  • the test chamber is sealed from the collection chamber.
  • communication between the isolation chamber and the test chamber is established.
  • a fluid releasing device is provided that opens the communication between the isolation chamber and the test chamber and establishes a fluid flow path to the test chamber.
  • the fluid releasing device may also establish a seal between the collecting chamber and the isolation chamber.
  • the specimen container may include a tamper evident lid which provides an identification of whether or not the container has been opened which may indicate that the contents of the container have been compromised.
  • a tamper strip may be releasably attached to the tamper evident lid which, in combination with the specimen container, permits one way rotation of the lid. Removal of the lid after closure to the locked position preferably results in partial or complete disconnection of the tamper strip from the lid. This feature reduces the possibility of sample adulteration and aids in ensuring the integrity of the diagnostic testing.

Abstract

Cette invention concerne un dispositif conçu pour recueillir et analyser un prélèvement fluide. Ledit dispositif comporte un récipient pour prélèvement ayant une chambre collectrice, une chambre d'isolation et une chambre d'analyse. La chambre collectrice est en communication fluidique avec la chambre d'isolation et isolée, de manière étanche, de la chambre d'analyse. La chambre d'isolation est également isolée de manière étanche de la chambre d'analyse. Le prélèvement fluide est recueilli dans la chambre collectrice et une aliquote de ce prélèvement est isolée dans la chambre d'isolation. Un élément de libération de fluide sert à libérer du fluide de la chambre d'isolation et à établir une voie d'écoulement vers la chambre d'analyse tout en assurant l'étanchéité de la chambre d'isolation par rapport à la chambre collectrice. Conformément à un autre aspect de cette invention, le récipient pour prélèvement peut comporter un couvercle inviolable qui permet de vérifier si le récipient a été ou non ouvert et d'indiquer, le cas échéant, que le contenu dudit récipient a été contaminé.
