Fluid transfer devices and methods of use

摘要

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 In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial.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. 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.

主权项

1. A disposable fluid transfer system for use with a substantially entirely closed system for the transfer of medical fluids between or among different medical fluid containers by an electronically controlled fluid dispensing system, the disposable fluid transfer system configured to be removably attachable to the electronically controlled fluid dispensing system, the disposable fluid transfer system comprising:
a first connector configured to be connected in fluid communication with a first fluid container, the first connector comprising a first sealing aperture that is configured to resist fluid within the disposable fluid transfer system from passing through the first sealing aperture when the first sealing aperture is closed; a second connector configured to be connected in fluid communication with a second fluid container, the second connector comprising a second sealing aperture that is configured to resist fluid within the disposable fluid transfer system from passing through the second sealing aperture when the second sealing aperture is closed; a measuring region, or an interface configured to be connected to a measuring region; a first valve configured to permit the passage of fluid from the first fluid container to the measuring region and configured to generally obstruct the passage of fluid from the measuring region to the first fluid container; a second valve configured to permit the passage of fluid from the measuring region to the second fluid container and to generally obstruct the passage of fluid from the second fluid container to the measuring region; and an interaction portion comprising a generally transparent housing portion and a generally opaque portion on a generally rigid valve portion, the interaction portion forming a portion of the disposable fluid transfer system such that the interaction portion is configured to permit the electronically controlled fluid dispensing system to detect the condition of the second sealing aperture when the valve portion moves into a light path in the electronically controlled fluid dispensing system; wherein the disposable fluid transfer system is configured to be attachable and detachable by a user from the electronically controlled fluid dispensing system, and wherein the disposable fluid transfer system is configured to resist fluid within the disposable fluid transfer system from passing outside of the disposable fluid transfer system upon disconnection of the disposable fluid transfer system from the first fluid container and the second fluid container.
