摘要： A check valve includes an upper housing defining an inlet of the check valve, and a lower housing having a support portion and defining an outlet of the check valve. The check valve further includes a chamber interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet, and a flexible diaphragm mounted in the chamber. The flexible diaphragm selectively permits fluid flow in a first direction, and prevents fluid backflow in a second direction opposite to the first direction. The flexible diaphragm includes a color changing material, and when the flexible diaphragm is seated on the support portion and bent due to force of the fluid flowing in the first direction, the flexible diaphragm exhibits a color change.

摘要： A specimen collection assembly (1700, 2000, 2600) configured for use with a medical fluid collection system (30) is disclosed which includes a housing (1701, 2001) configured for removable attachment to the fluid collection system (30); a first fitting (1734, 2664) attached to the housing (1701, 2001) and shaped to receive a suction line (50) that extends from a medical/surgical site; an outlet opening (1770, 2606) provided in the housing (1701, 2001) and through which, in use, fluid drawn through the first fitting (1734, 2664) flows through the housing (1701, 2001) and into the fluid collection system (30); and a porous screen (1890, 1914, 2741) configured to be disposed in the housing (1701, 2001) between the first fitting (1734, 2664) and the outlet opening (1770, 2606) for trapping material entrained in the fluid flow through the housing (1701, 2001). A supplemental opening (1729, 2030) is provided in the housing (1701, 2001), wherein the supplemental opening (1729, 2020) is separate from the outlet opening (1770, 2606) and opens into a first void space (1727, 2652) internal to the housing (1701, 2001). The first fitting (1734, 2664) opens into the first void space (1727, 2652) and there is a fluid path from the first void space (1727, 2652) to the housing outlet opening (1770, 2606). A first cap (1900, 1850, 2702) is configured for removable attachment to the housing (1701) so as to seat over the supplemental opening (1729, 2030), wherein the first cap (1900, 1850, 2702) has the porous screen (1890, 1914, 2741) shaped to occupy the first void space (1727, 2652, 2027) so that, when the first cap (1900, 1850, 2702) is disposed over the supplemental opening (1729, 2030) and in use, fluid that flows from the first fitting (1734) through the first void space (1727, 2652) to the outlet opening (1770, 2606) flows across the porous screen (1890, 1914, 2741). A second cap (1862, 1741) is configured for removable attachment to the housing (1701, 2001) so as to seat over the supplemental opening (1729, 2030), wherein the second cap (1862, 1741) does not have a screen so that, when the second cap (1862, 1741) is seated over the supplemental opening (1729, 2030) and in use, fluid that flows from the first fitting (1734) through the first void space (1727, 2652) is not filtered in the first void space (1727, 2652). A second fitting (1732, 2616) is attached to the housing (1701, 2001) and is shaped to receive a suction line, wherein the second fitting (1732, 2616) opens into a space (1704, 2604) in the housing (1701, 2001) other than the first void space (1727, 2652) and is in fluid communication with the outlet opening (1770, 2606).
