  • Patent number: 11933650
    Abstract: Various systems and methods for detecting air in a chamber of an infusion system are disclosed. In one embodiment, a determination is made that air is contained in the chamber on the basis of a change in the average force exerted against the plunger utilizing a derivative spike for event detection and a systematic reduction in the average force to confirm the nature of the change. In another embodiment, a determination is made that the chamber contains air when a difference between the current force profile and a baseline force profile crosses a threshold. In an additional embodiment, a force profile is classified as being an air force profile or a liquid force profile based on extracted features of the force profile.

  • Patent number: 11923076
    Abstract: Various techniques for facilitating communication with and across a clinical environment and a cloud environment are described. For example, a method for converting infusion pump messages having one format into standardized dataset messages having another format is described. When a connectivity adapter in the clinical environment detects a new pump protocol, the connectivity adapter may generate a message converter that can convert pump messages into standardized dataset messages. The message converter can be used to convert pump messages into standardized dataset messages. The standardized dataset messages may include information additional data or metadata not included in the pump messages.

  • Patent number: 11883623
    Abstract: A soft grip medical connector comprises a housing with an upstream end, a downstream end and a lumen extending through a central portion thereof. A flexible member comprises a valve portion integrally formed with a sleeve portion. The valve portion is positioned within a section of the housing and is configured to control a flow of fluid through the housing lumen. The sleeve is inverted to envelope at least a portion of the outer surface of the housing. In some embodiments the gripping portion is integrally formed with the valve portion. In some embodiments, the connector is also generally configured to create a positive pressure in a catheter lumen upon removal of a syringe or other medical device from the upstream end of the connector. Methods of making a medical fluid connector generally comprise forming a valve member with a sleeve extending there from, and assembling the valve, sleeve and housing.

  • Patent number: 11806308
    Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container.

  • Patent number: 11808389
    Abstract: A connector system for medical fluid includes a male connector and a female connector that have a closed configuration when detached from one another. The first end of the male connector is configured to mate with a first end of the female connector. When the male connector is coupled with the female connector, complementary structures engage to move seals away from ports in the male connector and the female connector, opening a fluid pathway through the connectors. The mating ends of the connectors are not exposed to the medical fluid when the connectors are coupled so that when the connectors are disconnected, the mating ends are substantially free of residual medical fluid.
