  • Publication number: 20230082981
    Abstract: An infusion pump includes first and pumping segments configured to operate in parallel with each other, each pumping segment including a group of serially-aligned pumping elements configured to compress an elongated compressible channel loaded within the pumping segment. Each group of serially aligned pumping elements of the multiple pumping segments is caused to pump according to respective timing patterns offset from each other to deliver a first fluid from a first compressible channel loaded in the first pumping segment to a common delivery tubing while filling a second compressible channel loaded in the second pumping segment with a second fluid, and to deliver the second fluid from second compressible channel to the common delivery conduit while filling the first compressible channel using the first pumping segment.

  • Publication number: 20220389294
    Abstract: Bonding dissimilar materials of medical device components can be carried out by applying an adhesive on at least one surface of two components which are composed of dissimilar materials and contacting the surfaces and exposing the contacted surfaces to heat and/or irradiate the adhesive to cure the adhesive and bond the surfaces. One medical component, e.g., medical tubing, can be composed of a non-polar, polyvinyl chloride free thermoplastic polymeric material and the other medical component, e.g., a medical connector, can be composed of polyacrylate, polyacrylonitrile, acrylonitrile-butadiene-styrene (ABS), methyl methacrylate-acrylonitrile-butadiene-styrene (mABS), polyester, and/or a polycarbonate material. The adhesive formulation can include: (a) a polyolefin oligomer having reactive acrylate groups and alkenyl groups, (b) an initiator, and optionally (c) a solvent.

  • Publication number: 20220133994
    Abstract: A medical pumping system is provided. The medical pumping system includes a fluid pump having a fluid inlet connection, a fluid outlet connection, an actuator and a backing surface. A tube of an intravenous set is disposed between the fluid inlet connection and the fluid outlet connection of the fluid pump, and disposed between the actuator and the backing surface, and a binding contact interface. The tube and the actuator are coupled together by the binding contact interface. The actuator is configured to actively pull a portion of the tube into an open position during a pump cycle. A medical pump and an infusion set are also provided.
