  • Patent number: 8777908
    Abstract: A luer connector including a housing with first end including a male luer tip and a second end. The connector further includes a rigid valve member having a first opened end and a second closed end and a retaining member configured to couple the valve member and the housing. The housing further includes a rigid conduit positioned within the housing and in fluid communication with the second end of the housing, the rigid conduit adapted to engage the first opened end of the valve member. The housing defines a first internal volume when the valve member is in a first position and a second, smaller volume when the valve member is in a second position.

  • Publication number: 20140188088
    Abstract: A medical connector for use with one or more medical implements. In some embodiments, the connector minimizes or eliminates the retrograde flow of fluid into the connector from one end or port upon the disconnection of a medical implement from the other end or port. In some embodiments, the connector generates a positive flow of fluid out of the connector from one end or port when a medical implement is disconnected from the other end or port.

  • Publication number: 20140174596
    Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a 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 In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial.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.

  • Publication number: 20140124528
    Abstract: In certain embodiments, a vial adaptor for removing liquid contents from a vial includes 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 includes 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: 8647310
    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.

  • Publication number: 20130304037
    Abstract: Some embodiments comprise a connector including a rigid housing having a first end and a second end. A second member can be positioned at a second end portion of the housing and be engageable with a second device. The second member can have a body portion having a first body portion, a second body portion, and a flow lumen extending axially through the body portion, an annular covering portion extending in a radial direction away from the body portion, a receiving portion extending away from the covering portion in an axial direction, and at least one protrusion extending radially away from an outside surface of the body portion. In some embodiments, the second member can be supported by the housing such that, in an assembled state, the first body portion is positioned within the housing and such that the annular covering portion and the second body portion are positioned outside the housing.

  • Publication number: 20130253478
    Abstract: A valve for selectively permitting a fluid flow between first and second medical implements is disclosed. The valve has a housing with an interface suitable for receiving a connector portion of a first medical device such as a catheter, and a seal made of a flexible material. The seal has a first end in fluid communication with the interface, a second end suitable for receiving the second medical device, and at least one slit in fluid communication with the first end and the second end. The slit defines a restricted fluid flow path and a relatively small interior volume when in an undisturbed state, defines an expanded fluid flow path and a larger interior volume upon the introduction of the second medical instrument into the slit, and retracts to define a restricted flow path and a small interior volume upon the withdrawal of the second medical device from the seal.
