Medical connector

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal with a collar and without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal.

Medical connector with elongated portion within seal collar

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. In some embodiments, the regulator assembly includes a flexible member configured to expand and contract in accordance with changes in the volume of the medical fluid in the vial. In some embodiments, the flexible member is substantially free to expand and contract. In some embodiments, the flexible member is not partly or completely located in a rigid enclosure.

Pressure-regulating vial adaptors

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.

A fluid transfer device can include a first attachment portion configured to engage a first port of a source container and a second attachment portion configured to engage a second port of an intermediate container. The first attachment portion can include a first projection defining a first fluid passage and the second attachment portion can include a second projection defining a second fluid passage. The fluid transfer device can further include a selector portion for selectively transitioning the fluid transfer device from a first configuration in which a flow path between the first and second fluid passages is closed to a second configuration in which the flow path between the first and second fluid passages is open. The fluid transfer device can further include a limiter configured to inhibit the selector portion from selectively transitioning the fluid transfer device from the first configuration to the second configuration.

Fluid transfer device and method of use for same

Disclosed is a first medical connector configured to be removably attachable with a second medical connector to permit fluid flow between the first and second medical connectors. The first medical connector can include a first region with a luer-compatible connection portion being configured to engage luer-compatible medical devices, and a second region comprising a resilient seal and a first luer-incompatible connection portion. The first luer-incompatible connection portion can inhibit engagement with luer-compatible medical devices and permit engagement with a second luer-incompatible connection portion of the second medical connector. In some embodiments, the first region of the first medical connector does not rotate with respect to the second region of the first medical connector in an initial stage of use, but the first medical connector is configured to transition from the initial stage of use to a subsequent stage of use in which the first region of the first medical connector and the second region of the first medical connector can be rotated with respect to each other.

Medical connector with luer-incompatible connection portion

An example of an electronic medical fluid transfer device can comprise a fluid transfer module with a multidirectional flow control valve and an intermediate container or pumping region, a sensor configured to detect whether at least one of a vacuum or gas is present in the fluid transfer module, a first electromechanical driver configured to interface with and control the multidirectional flow control valve on the fluid transfer module, a second electromechanical driver configured to be mechanically linked to and control the intermediate container or pumping region according to an operational parameter, and one or more computer processors configured to communicate electronically with the sensor and the first and second electromechanical drivers to determine the operational parameter based on a flow characteristic of medical fluid to be transferred and adjust the operational parameter based on output of the sensor.

Systems, methods, and components for transferring medical fluids

A medical connector for use in a fluid pathway. A valve member with sealing rings helps preclude undesired accumulation of fluid within the connector. A branched connector includes a fluid diverter extending away from a port of the branched connector. The fluid diverter is configured to divert fluid flowing through the branched connector and into a medical connector attached thereto, flushing a distal portion of the medical connector.

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.

Medical connector with closeable luer connector

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.

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.

Systems, methods, and components for trapping air bubbles in medical fluid transfer modules and systems

Some embodiments disclosed herein relate 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. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.
