Abstract: A fluid is aspirated from a sealed container (12) and a precise quantity of the aspirated fluid is dispensed. The method involves standard steps of inserting a probe (20 into the container (12) through the container seal (14) and aspirating bubbles and the selected quantity of fluid into the probe before removing the probe from the container and dispensing the fluid. The method also includes an additional step performed at at least one stage in the method to assure that, before the dispensing operation is performed, sample fluid in the probe extends to the end of the probe without any fluid extending beyond the end of the probe. For one embodiment of the invention, both the selected quantity of fluid to be dispensed and a selected extra volume of fluid are initially aspirated and, prior to the dispensing step, a selected quantity of the sample which is greater than the maximum amount that air bubbles in the probe might shrink as a result of the pressure in the container being less than the pressure outside the container, but less than the selected extra volume, is wasted. An additional step might be to withdraw a volume of fluid from the probe before the probe is inserted into the container which is substantially equal to the fluid and air bubbles to be aspirated, such fluid being replaced by air entering the probe and then dispensing such volume of air from the probe into the container after the probe has been inserted into the container. A hollow needle (18) may also be inserted into the container prior to the aspiration operation to equalize the pressure inside and outside the container before the above step is performed or, the pressure and air volume in the container may be determined and used to calculate the change in air volume of air bubbles which will occur when the probe is removed from the container and this information used to compensate for such increase or shrinkage when fluid is removed from the probe prior to insertion into the container and when air from the probe is injected into the container after insertion.

Abstract: A method and apparatus are provided for accessing a sealed container (12), and in particular a sealed container which is at a pressure other than atmospheric and which generally contains blood or other bodily fluid. A piercer (60) and a probe (62) are provided which are mounted to a XYZ positioning mechanism (30) and are controlled such that the piercer (60) passes through a stopper or seal (14) of the container (12), forming a cut therein through which the probe (62) may subsequently enter the container. A foot mechanism (64, 66, 68) is provided which is held against the stopper or seal for the container during piercer or probe removal for stripping purposes and through which the probe and piercer pass, the size and shape of the foot (68) bing such that for both piercing and probing operations, it is over only a single container (12). The piercer (60) and probe (62) are operated such that the one not being used is in each instance in a raised position relative to the one being used. A lubrication station is provided in which the piercer is dipped prior to use to facilitate the piercing operation, to coat the cut and to minimize stopper debris. A wash station is also provided.

Abstract: SE SUMINISTRAN UN METODO Y UN APARATO PARA ACCEDER A UN RECIPIENTE (12) SELLADO, Y EN PARTICULAR A UN RECIPIENTE SELLADO QUE ESTA A UNA PRESION DISTINTA DE LA ATMOSFERICA Y QUE CONTIENE SANGRE O CUALQUIER OTRO FLUIDO CORPORAL. SE SUMINISTRAN UN CORTADOR (60) Y UNA SONDA (62) MONTADOS SOBRE UN MECANISMO (30) DE POSICIONAMIENTO XYZ QUE SON CONTROLADOS DE FORMA QUE EL CORTADOR (60) PASE A TRAVES DE UN TAPON O SELLO (14) DEL RECIPIENTE (12), FORMANDO UN CORTE EN SU INTERIOR A TRAVES DEL CUAL LA SONDA (62) PODRA SUBSECUENTEMENTE ENTRAR EN EL RECIPIENTE. SE SUMINISTRA UN MECANISMO DE PIE (64, 66, 68) QUE ES MANTENIDO CONTRA EL TAPON O SELLO DEL RECIPIENTE DURANTE EL CORTE O RETIRADA DE LA SONDA A OBJETOS DE PURIFICACION Y A TRAVES DE LA CUAL PASAN LA SONDA Y EL CORTADOR, SIENDO EL TAMAÑO Y FORMA DEL PIE (68) TALES QUE LAS OPERACIONES DE CORTADO Y DE LA SONDA SE REALIZAN SOLAMENTE EN UN SOLO RECIPIENTE (12). EL CORTADOR (60) Y LA SONDA (62) SE OPERAN DE FORMA QUE NO SE USAN EN CADA CASO EN UNA POSICION ELEVADA CON RELACION A LA QUE ESTA SIENDO UTILIZADA. SE SUMINISTRA UNA ESTACION DE LUBRICACION EN LA CUAL SE SUMERGE EL CORTADOR ANTERIOR A SU USO PARA FACILITAR LA OPERACION DE CORTE, PARA REVESTIR EL CORTE Y PARA MINIMIZAR LOS RESIDUOS PROCEDENTES DEL TAPON. TAMBIEN SE SUMINISTRA UNA ESTACION DE LAVADO.
