Abstract
A filtering device is provided to an analyzing instrument to block the passage of oversized particles that may otherwise clog the aperture of a sample analyzing device. The filtering device can be arranged to be proximate to the mixing chamber. In certain examples, the filtering device is placed at or adjacent an output port of the mixing chamber.
Claims12
A method of filtering a sample in an analyzing instrument, the method comprising:
- securing a filtering device proximate to a chamber, the filtering device configured to prevent at least some of oversized particles from passing therethrough;
- and
- connecting a flow tube to an outlet port of the chamber to form a fluid communication path between the chamber and a sample analyzing device.
A filtering device for filtering a sample in a hematology analyzer, the filtering device comprising:
- a plate having a plurality of apertures configured to prevent at least some of oversized particles from passing therethrough while enabling particles to be analyzed to pass therethrough, the oversized particles at least partially generated from a sample container as an aspiration device pierces the sample container, the plate configured to be secured proximate to an outlet port of a chamber.
A system for filtering a sample in an analyzing instrument, the system comprising:
- a flow tube fitting to an outlet port of a chamber and configured to form a fluid communication path between the chamber and a sample analyzing device;
- and
- a filtering device arranged proximate to the chamber, the filtering device configured to prevent at least some of oversized particles from passing therethrough while enabling particles to be analyzed to pass therethrough, the oversized particles at least partially generated from a sample container as an aspiration device pierces the sample container to aspirate at least a portion of the sample from the sample container.
