Abstract
A collection fitting, system, and method for sampling fluid from a tissue site is described. The collection fitting includes a switch fitting having a first passage and a second passage. The collection fitting also includes a bypass switch coupled to the switch fitting. The bypass switch is operable to fluidly couple the first passage and the second passage through the bypass switch. The bypass switch is also operable to fluidly couple the first passage and the second passage through a specimen container.
Claims41
A collection fitting for sampling fluid from a tissue site, the collection fitting comprising:
- a switch fitting having a first passage and a second passage;
- and
- a bypass switch coupled to the switch fitting and operable to fluidly couple the first passage and the second passage through the bypass switch, and in response to movement of the bypass switch, operable to fluidly couple the first passage and the second passage through a specimen container.
A collection fitting for sampling fluid from a tissue site being treated with reduced-pressure therapy, the collection fitting comprising:
- a switch fitting configured to be fluidly coupled between a reduced-pressure source, a dressing, and a specimen container;
- and
- a switch coupled to the switch fitting and configured to selectively couple a fluid path between the reduced-pressure source and the dressing through the switch and the specimen container.
A system for sampling fluid from a tissue site, the system comprising:
- a switch fitting having a first passage and a second passage;
- a specimen container;
- a switch configured to fluidly couple the first passage and the second passage through the switch, and in response to operation of the switch, to fluidly couple the first passage and the second passage through the specimen container;
- a first tube coupled to the first passage;
- and
- a second tube coupled to the second passage.
A method for sampling fluid from a tissue site comprising:
- providing a collection fitting having a switch;
- fluidly coupling the collection fitting between a reduced-pressure source and a tissue site so that the reduced-pressure source and the tissue site are fluidly coupled through the collection fitting;
- coupling a specimen container to the collection fitting proximate to the switch;
- and
- operating the switch to fluidly couple the tissue site and the reduced-pressure source through the specimen container.
A collection fitting for sampling fluid from a tissue site, the collection fitting comprising:
- a chassis having a tubular body;
- a disc cup having a cylindrical body, a first passage, and a second passage, the disc cup disposed in the chassis;
- a cap coupled to the chassis and having a first cap passage in fluid communication with the first passage of the disc cup and a second cap passage in fluid communication with the second passage of the disc up, the first cap passage and the second cap passage each configured to be coupled to a tube;
- and
- a switch disposed within the chassis adjacent to the disc cup and having a first port, a second port and a bypass passage, the switch selectively operable to fluidly couple the first passage and the second passage with the bypass passage and to fluidly couple the first passage to the first port and the second passage to the second port.
