Abstract

See full text

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 In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial.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