Patent number: 11541171Abstract: A portable electronic fluid dispensing system can provide pre-filled, pre-primed IV bag assemblies comprising therapeutic fluids. The same fluid line and connector in the IV bag assembly can be used to fill the IV bag as is used to withdraw fluid from the IV bag and infuse such fluid into the patient. The connection points along the IV assembly, such as the connection between the IV bag and a drip chamber, or between an IV bag and tubing, or between a drip chamber and tubing, or between tubing and a closeable, resealable connector, can each be resistant to disconnection by a user. The healthcare practitioner at the patient care site is not required to attach any of these components to each other, and the healthcare practitioner at the patient care site is not required to introduce a spike into a spike port on the IV bag.Type: GrantFiled: December 20, 2017Date of Patent: January 3, 2023Assignee: ICU Medical, Inc.Inventors: Jay Hachey, Thomas McCall, Jason Woodbury

Patent number: 11541220Abstract: A needleless connector and methods for preventing microbial ingress in medical device connections are disclosed. Various examples provide a needleless connector including a male luer having a recessed distal tip surface containing a water-soluble antimicrobial composition. Further examples include a trap for retaining antimicrobial composition. As the needleless connector is inserted into a female connector, a tapered surface distal edge acts to push microorganisms, while the distal tip surface is configured to leave microorganisms undisturbed. After insertion of the needleless connector, microorganisms present on the female luer surface are biased to reside in the recess region. The recess, trap, and antimicrobial composition are configured to facilitate a long-lasting supply of antimicrobial solution within the fluid-filled recess, at the same time confining the antimicrobial solution inside the recess.Type: GrantFiled: June 20, 2019Date of Patent: January 3, 2023Assignee: ICU Medical, Inc.Inventors: Robert J.
