Abstract
A filtration system may include a chamber and a filter disposed within an interior the chamber. A closed end, or a tip, of the filter may face an inlet into the interior of the chamber. An open end, or a base, of the filter may surround an outlet from the interior of the chamber. As a sample passes through the interior of the chamber, solid and/or semisolid material in the sample may be collected between an exterior surface of the filter and an interior surface of the chamber, and may be viewed through the chamber.
Claims20
A filtration system that filters medical aspirant obtained from a body of a subject, comprising:
- a chamber with a distal side including an inlet port, a chamber interior in communication with the inlet port, and a proximal side including an outlet port in communication with the chamber interior;
- and
- a filter within the chamber interior, the filter being elongated and including an open end, a closed end, and a filter interior between the open end and the closed end, the closed end having a smaller dimension than the open end, the closed end being oriented toward the distal side of the chamber, the open end being oriented toward the proximal side of the chamber.
A method for aspirating a sample from a body of a subject, comprising:
- positioning a distal end of an elongated medical device at a location of the body of the subject from which the sample is to be obtained;
- securing the elongated medical device to an inlet of a chamber of a filtration system;
- placing an aspirator in fluid communication with an outlet of the chamber;
- using the aspirator to draw the sample from the elongated medical device into the chamber;
- and
- capturing solid and/or semisolid material between a filter in an interior of the chamber and a wall of the chamber.
