  • 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: 11302432
    Abstract: A medication infusion device comprises a memory means at a medication reservoir storing data identifying medication in the reservoir, a memory reading means at an infusion pump unit reads data from said memory means, and control means controls an infusion, based on data read by said memory reading means, to start the infusion when the medication is correct. A fluid connection detection means detects fluid connection of the medication reservoir to the infusion pump unit and transmits to control means whether the medication reservoir is connected. The control means controls an infusion in accordance with the transmission from the fluid connection detection means so that when there is no connection between the medication reservoir and infusion pump unit, the infusion pump unit will not be started or, if already started, stopped.

  • Patent number: 11207512
    Abstract: A medical valve assembly includes a tube extending between proximal and distal tube ends. A plunger plate extends radially from the distal tube end, and a valve housing surrounds the tube and extends between proximal and distal valve housing ends. The valve housing includes a flange extending radially inwardly from the distal valve housing end and disposed in spaced relationship with the plunger plate to define a distance dimension D extending therebetween. An elastomeric seal is compressed between the plunger plate and the flange to establish a closed condition of the medical valve assembly. The elastomeric seal axially moves one of the valve housing and the tube relative to the other when a medical device is inserted into the medical valve assembly to automatically increase the distance dimension and establish an open and sealed condition of the medical valve assembly with the inserted medical valve.
