  • Patent number: 11311660
    Abstract: A method for operating a fluid management system includes automatically detecting an unstable condition in the system, which may include detecting a large change in the supply fluid amount (indicative of a bag change), detecting a large change in the waste fluid amount (indicative of a bag change), or detecting a large difference between the amount of fluid dispensed as measured by the weight data and the amount of fluid dispensed as measured by the flow data (indicative of a blockage in the supply tubing). The method further includes adjusting the operating mode of the system during the unstable condition, which may include switching to using flow data rather than weight data to track the fluid deficit during a supply bag exchange, halting operation of an outflow pump during a waste container exchange, and/or halting operation of the system during a blockage in the supply tubing.

  • Patent number: 10105899
    Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.

  • Patent number: 10092173
    Abstract: The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool. An endoscope-coupled part and a treatment tool-coupled part are provided inside the slider, and the slider has a dead zone where the forward and backward movement of either the endoscope or the treatment tool does not interlock with the movement of the other and a sensing zone where the forward and backward movement of either the endoscope or the treatment tool interlocks with the movement of the other. The overtube body includes a distal-end-side stopper and a base-end-side stopper that restrict the movable range of the slider. A length L from a coupling position of the endoscope to a distal end position of the overtube body and a length Ls from the coupling position of the endoscope to a distal end position of the endoscope are set to satisfy Ls?L.

  • Patent number: 10046154
    Abstract: Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.
