  • Patent number: 11559467
    Abstract: In some embodiments, a medical fluid connector is configured to receive an emitter of therapeutic agents to be emitted into a fluid pathway within the connector, the medical fluid connector comprising a proximal female end, an intermediate region, a distal male end, and a fluid pathway extending from the proximal female end, through the intermediate region, to the distal male end. A retaining structure is positioned within the intermediate region.

  • Patent number: 11541171
    Abstract: 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.

  • Patent number: 11541220
    Abstract: 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.

  • Patent number: 11501877
    Abstract: A distributed network system and method includes a processing unit configured to manage safety data for a plurality of medical devices, a database software component in communication with the processing unit, and a monitoring software component in communication with the processing unit. The monitoring software component is configured to monitor a number of messages between a number of medical devices and the processing unit, to process performance parameters to generate an overall performance index, and to generate an output that is viewable by a user. The output includes relative contributions of each of the performance parameters to the overall performance index, where the overall performance index is generated using a weighting factor associated with each of the performance parameters. The performance parameters include the number of messages waiting to be processed, which has the largest weighting factor, and a disk queue length, which has the smallest weighting factor.

  • Patent number: 11478624
    Abstract: Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.

  • Patent number: 11437132
    Abstract: A drug library management system generates versions of drug library data that can be used by infusion pumps, and version of drug library data that can be used by systems or components in a clinical environment other than infusion pumps. One version of the drug library data may be customized for a particular infusion pump, while another version may be a generalized version that can be used by middleware systems that process messages received from various infusion pumps that are using a different version of the drug library data. The generalized version may be archived separately from a drug library database used by the drug library management system to generate the various versions.

  • Patent number: 11433177
    Abstract: In one step of a method for infusing an infusion fluid, the infusion fluid is pumped through a fluid delivery line of an infusion system. In another step, measurements are taken with at least one sensor connected to the infusion system. In an additional step, an air determination is determined with at least one processor. The air determination is related to air in the fluid delivery line. The air determination is based on the measurements taken by the at least one sensor. The air determination is further based on: (1) medication information regarding the infusion fluid or infusion information regarding the infusion of the infusion fluid; or (2) multi-channel filtering of the measurements from the at least one sensor or non-linear mapping of the measurements from the at least one sensor; and statistical process control charts applied to the multi-channel filtered measurements or applied to the non-linear mapped measurements.
