Abstract: A urine meter attached to a flexible urine collection bag. The urine meter comprises a rigid container which is dischargeable into the collection bag. A valve is disposed at the bottom of the rigid container to permit small samples to be taken in a sterile, multiple use, manner. The valve also permits large urine samples to be taken from the container, by the release of a bias device on the valve. The large samples are taken infrequently. The small samples are taken from a reusable sampling port which reseals itself when the sampling device, such as a hypodermic needle, is withdrawn.

Abstract: A multiple sample valve assembly for a urine collection system with a valve for taking small urine samples in a safe manner. The valve also has a valve for taking large urine samples while having a frangible portion for indicating that the large sampling valve was used, so as to alert medical personnel to the possibility of contamination or infection if proper procedures are not undertaken. The element for indicating use comprises frangible panels or bands which may be disturbed by opening the valve.

Abstract: A urine meter comprising, a container having a cavity for collection of urine, and a drainage tube for draining urine from a patient. The urine meter has a receptacle having a chamber, with the drainage tube communicating with an upper portion of the receptacle for passage of urine into the chamber. The urine meter has a conduit of flexible material communicating between an upper portion of the receptacle and an upper portion of the container, with the conduit having a curve from the container to the receptacle, an outer corrugated wall, and an inner smooth wall. The receptacle is releasably supported on a front side of the container.

Abstract: A liquid drainage system comprising, a receptacle having a chamber to receive liquid, and a depending annular wall in an upper portion of the receptacle. The system has a valve comprising a cup-shaped member of elastic material having a lower wall extending across the cup-shaped member, an upper annular wall extending from the lower wall, with an upper portion of the valve annular wall being snugly received on a lower portion of the receptacle wall, and a hinge member extending outwardly from the cup-shaped member at one side of the lower wall. The cup-shaped member has a slit extending through the cup-shaped member to the hinge member at a location slightly above the lower wall. The slit defines a valve seat above the lower wall with the lower wall serving as a valve element which may sealingly engage against the seat, with the hinge member connecting the lower wall and valve annular wall.

Abstract: A liquid drainage system comprising, a receptacle having a chamber to receive liquid, and a depending annular wall defining a valve seat at a lower portion thereof and an opening in the region of the seat. The system has a valve element comprising a sheet of flexible relatively stiff material being sufficiently large to extend across the opening and sealingly engage against the seat peripherally around the wall. The system has a device for retaining a central portion of the valve element adjacent the seat.

Abstract: A liquid drainage system comprising, a receptacle having a chamber to receive liquid, a depending annular wall defining a valve seat at a lower portion thereof and an opening in the region of the seat, and a retainer assembly extending across the opening and having an aperture extending therethrough in the opening. The system has a valve element of elastic material comprising a disc being sufficiently large to extend across the opening and sealingly engage against the seat peripherally around the wall. The valve element has a stem extending from the disc and being slidably received in the aperture. The stem has a boss spaced from the disc with dimensions larger than the aperture such that the boss maintains the stem in the aperture. The stem has a sufficient length between the boss and disc such that the disc is spaced from the seat when the boss engages against the retainer assembly.

Abstract: A flushing device comprising, a housing having an inlet, an outlet, a cavity communicating between the inlet and outlet and defining an annular valve seat, and an opening communicating with the cavity, with the valve seat facing away from the opening. The device has an elastic valve element received in the cavity with an annular valve portion sealingly engaged against the seat. The valve element has a stem extending through the opening and the stem sealingly engages against the portion of the housing defining the opening. The valve element has a passageway extending therethrough and communicating between the inlet and the outlet, and the device has a relatively large channel communicating between the inlet and seat and between the seat and outlet. The device has an insert extending across the passageway and having a relatively small bore.

Abstract: A midstream sampling device comprising, a housing having a chamber, a distal outer mouth defining an outer port, an inner mouth in the chamber defining an inner port, and an outlet opening. The housing has a first cavity communicating between the inner port and the outlet opening, and a second cavity at least partially below the inner mouth and communicating with the outer port. The housing has an elongated depending post having a channel, and an upper aperture communicating with at least one of the cavities. The device also has a receptacle having a chamber communicating with the outlet opening.

Abstract: A protective headgear comprising a helmet and a pad assembly. The pad assembly comprises a pad of foam material having an integral densified layer defining front and side surfaces of the pad assembly and forming a tear-resistant cover for the pad. The pad assembly has a relatively rigid attachment plate bonded to the pad adjacent a back surface of the pad assembly for securing the pad assembly to the helmet.

Abstract: A device for measuring a discharge of urine comprising, a receiving member having an inlet port to receive the discharge, and a receptacle having a chamber to receive the discharge from the receiving member, and means for measuring a dynamic characteristic of the discharge. The device has a container attached to the receptacle to receive the discharge passing from the receptacle.

Abstract: A protective helmet comprising a shell, and flexible liner means positioned in the shell to dissipate forces applied against the helmet, with the liner means having fluid filled chamber means and a plurality of openings extending through the liner means. The helmet also has a plurality of resilient pad means positioned in the openings with at least a portion of the inner surfaces of the pad means being spaced from an inner surface of the liner means.

Abstract: A protective helmet comprising, a shell, and liner means of a flexible material having fluid filled chamber means and a relatively soft inner surface for contacting the wearer's head. The helmet also has a second liner of resilient material positioned intermediate at least a portion of the liner means and the shell.
