  • Publication number: 20210205175
    Abstract: In certain embodiments, a vial adaptor comprises a housing configured to couple the adaptor with a vial, an access channel, a regulator channel, and a regulator assembly. The access channel is configured to facilitate withdrawal of fluid from the vial when the adaptor is coupled to the vial. The regulator channel is configured to facilitate a flow of a regulating fluid from the regulator assembly to compensate for changes in volume of a medical fluid in the vial. The regulator assembly can include a valve configured to transition between a closed configuration and an opened configuration.

  • Publication number: 20210162191
    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: 11020541
    Abstract: Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

  • Patent number: 11013664
    Abstract: In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a piercing member and a bag. The bag can be contained within the piercing member such that the bag is introduced to the vial when the vial adaptor is coupled with the vial. In some embodiments, the bag expands within the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In other embodiments, a vial comprises a bag for regulating pressure within the vial as liquid is removed therefrom. In some embodiments, a vial adaptor is coupled with the vial in order to remove the liquid. In some embodiments, as the liquid is removed from the vial via the adaptor, the bag expands within the vial, and in other embodiments, the bag contracts within the vial.

  • Patent number: 11007119
    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: 10987277
    Abstract: According to some embodiments of the present disclosure, an adaptor configured to couple with a sealed vial can include a connector interface. The adaptor can include one or more access channels (e.g., passages). In some cases the one or more access channels are in fluid communication with the connector interface. The adaptor can include a piercing member. The piercing member can include a regulator channel. The adaptor can include a regulator assembly. The regulator assembly can include a first regulator inlet. In some cases, the regulator includes a second regulator inlet. One or more of the first and second regulator inlets can include a filter configured to filter fluid passing into and/or out of the respective regulator inlets. One or more valves can be positioned between the first and/or second regulator inlets and the piercing member.

  • Publication number: 20210106805
    Abstract: A therapeutic delivery device for medical connectors and tubing can be used to perform an antimicrobial lock procedure. The therapeutic delivery device can include a head portion configured to attach to a medical fluid connector and a distally extending projection configured to be inserted into the medical fluid connector. At least a portion of the projection or an entire surface of the therapeutic delivery device can be coated with antimicrobial material(s), such as chlorhexidine gluconate, and can be in contact with a fluid in a catheter coupled to the medical fluid connector to form an antimicrobial locking solution.

  • Publication number: 20210093850
    Abstract: Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.

  • Publication number: 20210046301
    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.
