Patent number: 7219468Abstract: An apparatus for automatically watering a plant in a container by regulating a flow of water to the container through flexible tubing. Upper and lower jaw members are interconnected by a horizontal pivot axis so that they develop a scissors action. A jaw area is formed on one side of the pivot axis for receiving the flexible plastic tubing, and a compression spring is mounted on the opposite side to provide resistance to closing of the jaw area. For use with pots and other non-hanging containers, the container is rested atop the upper jaw member on the side towards the jaw area so that the weight of the container acts directly to compress and close the jaw area. Baskets and other hanging containers are suspended from the other ends of the jaw members so that the tension caused by the weight of the container causes the jaw area to pivot closed.Type: GrantFiled: April 4, 2005Date of Patent: May 22, 2007Inventor: Maurice A. Muxlow

Publication number: 20040089828Abstract: A conduit clamp for selectively opening and closing the fluid path of a tube includes an upper and lower member pivotally connectable to each other. The upper member has a depression on an upper surface to allow for manual activation for opening and closing the conduit clamp. The lower member has a pair of opposing walls with a cam race formed on the interior surface of each wall for receiving and moving laterally extending pins on the upper member as the conduit clamp is depressed into the locked and closed position and depressed again to be in the open position. The cam race forms a pin bottom stop position, a pin lock position and a pin return ramp position for each laterally extending pin.Type: ApplicationFiled: October 17, 2003Publication date: May 13, 2004Inventor: Albert A. Werth

Patent number: 6644618Abstract: A fast-fit clamp for partly or fully closing flexible tubes, in particular for medical use, has a laminar body bent backwards on itself, fitted through longitudinally with a tube, and having two elastically competing ends between which project radially inwards two opposite transverse teeth for gripping the tube; at least two split through holes being formed in the laminar body, with openings facing outwards on opposite sides; and provision being made for centering means for centering the competing ends, and latch means for fastening the competing ends simply or gradually.Type: GrantFiled: December 7, 2001Date of Patent: November 11, 2003Inventor: Enrico Balbo

Patent number: 6261269Abstract: The invention relates to devices for draining biological fluids. A first device comprises a housing (2) and a pinch valve (3) mounted in the housing, away from the walls of the latter. The housing includes an opening (11) arranged opposite the pinching means (6) of the valve. Another device (13) comprises a catheter section (7) of a drainage line and a member (12) for supporting the catheter, the catheter section passing into and emerging from the support member (12) at two points and forming a loop between these two points.Type: GrantFiled: July 9, 1999Date of Patent: July 17, 2001Assignee: NMT Neurosciences Implants S.A.Inventor: Alain Lecuyer

Patent number: 6234448Abstract: A pinch clamp for enabling a collapsible tube to be pinched so as to prevent fluid from flowing within a lumen in the tube. The clamp is mountable onto the tube in a lateral direction and is adapted for use with tubes having diameters within a predetermined range. Means are provided for preventing the clamp from disengaging from the tube when in the unclamped position.Type: GrantFiled: November 12, 1999Date of Patent: May 22, 2001Assignee: Medivice Systems Ltd.Inventor: Gad Porat

Patent number: 6196519Abstract: A molded squeeze clamp for tubing which comprises a strip of plastic having first and second ends, the strip being bent back on itself so that the ends are adjacent to each other in the manner of a Halkey-Roberts clamp. The first strip end defines a first latch, for engagement and releasable locking with the second end, and the second end defines a second latch for locking with the first latch. The first end also defines a first projection extending towards the second end to reduce or eliminate a gap between the first and second ends when the clamp is in its unstressed, as-molded, open configuration. The second end defines a second projection to facilitate manual opening of the clamp, the second projection extending in substantially longitudinal relation to the axis of tubing carried in the squeeze clamp.Type: GrantFiled: September 15, 1999Date of Patent: March 6, 2001Assignee: DSU Medical CorporationInventor: David S. Utterberg

Patent number: 6161812Abstract: A resilient clamp comprises a body forming in one single piece an upper arm and a lower arm connected to each other at one side by a springing curved end portion and provided at the other side with an anchoring element and an anchoring member, respectively, which are mutually releasably snap engageable. The upper arm has a manoeuvre portion superelevated with respect to the anchoring element. Further structural features of the body afford reducing the closing effort and minimizing any risks of unintentional opening of the clamp.Type: GrantFiled: January 8, 1999Date of Patent: December 19, 2000Assignee: Industrie Borla SpAInventors: Gianni Guala, Ernesto Guala
