  • Publication number: 20200376254
    Abstract: A device to couple a vascular access device to a medical device may include a body, a spring, and a housing. The body may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The proximal end of the body may include a connector. The housing may be coupled to a proximal end of the spring and may enclose the connector. A distal end of the spring may be coupled to the body. The housing may include a flap, which may include an antimicrobial compound. When the housing is disposed in a proximal position, the flap may cover the connector, the antimicrobial compound may contact the connector, and the spring may be uncompressed. In response to movement of the housing from the proximal position to a distal position, the spring may be compressed and the flap may open.

  • Publication number: 20200282140
    Abstract: An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

  • Patent number: 10682499
    Abstract: A catheter and introducer needle assembly, including a flexible catheter and a catheter hub having an outer surface portion. The assembly includes an introducer needle disposed in the catheter, a needle shield having a resilient clip adapted to flex between first and second positions. The resilient clip includes a cantilevered arm with a pawl. In the resilient clip's first position, the cantilevered arm is flexed so that the pawl frictionally contacts the catheter hub's outer surface portion to retain the needle shield with the catheter hub. In the second position, the pawl no longer frictionally contacts the hub's outer surface, thereby permitting needle shield displacement relative to the catheter hub.

  • Publication number: 20200179613
    Abstract: Catheter and needle assemblies with spring-powered retractable needles are described. The assemblies can include a hollow handle, a grip portion, a catheter hub with a catheter, and a needle. The needle can have a first position in which the needle is slidably disposed within the catheter and a second position in which the needle is slidably removed from the catheter and retracted at least in part into the hollow handle. The grip portion can include a trigger portion that activates a spring to move the needle from the first position into the second position. In the second position, a sharp distal point of the needle is shielded by the grip portion to prevent accidental needle sticks.
