  • Publication number: 20240189569
    Abstract: A vent device (100, 140) for venting gas from a line of a medical device having gas to be removed has several different variations. The vent device can include an inlet (102) in communication, when in use, with an interior of the line, and an outlet (104) in communication with air outside the line or is open to the atmosphere. The inlet and the outlet define opposite ends of a flow path (106) configured to vent gas from the interior of the line out to the outside of the line, and to inhibit flow of liquid from the interior of the line out the outlet of the vent device.

  • Publication number: 20240189566
    Abstract: Intravenous sets, port assemblies, and vascular access assemblies can include a vent device for venting gas trapped therein. The vent device can connect to a connector, such as a needleless port having a valve, and the connector connected to an adapter. The vent device can have a valve opener, an engagement body, and a gas-permeable vent incorporated with the valve opener. In use, the valve opener is moveable from an initial non-venting condition, in which the valve opener does not actuate the valve and is held in-register with the valve by the engagement body, to a venting condition, in which the valve opener is actuated to open the valve to allow gas to pass from within the system the connector is connected to then flow out through the gas-permeable vent.

  • Patent number: 11701465
    Abstract: A sensor system for a volumetric pump operating according to the linear peristalsis principle includes at least one sensor unit; at least one sensor transmitter unit; and a sensor output signal processing unit. The sensor transmitter unit is arranged to apply a detection variable varying as a function of a travel position to the sensor unit along a predetermined travel along which a fixedly arranged sensor unit and a movably arranged sensor transmitter unit or a movably arranged sensor unit and a fixedly arranged sensor transmitter unit are moving relative to each other. The sensor unit is configured to output a detection signal corresponding to a travel position on the basis of the varying detection variable. The sensor output signal processing unit is arranged to receive the detection signal output by the sensor unit and discriminate at least three travel positions on the basis of the received detection signal.

  • Patent number: 11602616
    Abstract: A needle assembly includes a catheter hub, a catheter tube extending distally from the catheter hub, and a needle hub having a needle having a needle tip extending out the catheter tube. A protective cap is positioned with the catheter hub and covers the catheter tube and the needle tip. The protective cap has a casing having a casing body, a first opening at a proximal end of the casing body, a proximal cavity having the needle tip and the catheter tube located in the proximal cavity, a second opening at an end opposite the first opening and opening into a distal cavity, and a rim at the second opening. A lid is removably attached to the rim at the second opening to seal a solution inside the distal cavity. The solution is dispensable from the distal cavity following separation of the lid from the rim.
