INTRAVENOUS INFUSION PUMPS WITH SYSTEM AND PHARMACODYNAMIC MODEL ADJUSTMENT FOR DISPLAY AND OPERATION
An infusion pump can determine and display what the drug load is inside of a patient by taking into account various factors such as drug half-life, pump pauses, and delays while a drug moves from a pump to a patient. A pump can also calculate and provide times when: medication will reach the patient; the drug concentration will reach a specified level; and a physiological response is expected. The pump can compensate for pauses in the delivery—for example, by infusing larger boluses of the drug into the patient within safe boundaries for concentration and timing. The pump can also predict what the drug load or concentration will be in the patient over time after the infusion stops by providing a graph, and in some cases act on such predictions by changing a flow rate or other parameters.

A drug infusion device determines whether an infusion program is stored within a memory. If so, a user is prompted to confirm usage of the program and a drug identifier, and to review the configuration of the device. If the program is not in the memory, the drug infusion device is enabled to receive an auto program with which it can configure itself. When auto program receipt is enabled, the drug infusion device waits for the auto program or for a selection for manual entry of the infusion program. A menu screen is displayed to indicate that the drug infusion device is waiting for the auto program, but the menu screen is not displayed if the auto program is already received. Therefore, a waiting for auto program menu screen may be avoided in many cases, reducing device setup time. In some embodiments, removal of a drug vial resets the device to a point after a power-on self-test and thus provides an easy method for resetting the device to a point that avoids unnecessary steps and expands a window of opportunity for receiving an auto program compared to prior work flows.

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 In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial.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