  • Publication number: 20150141955
    Abstract: An infusion pump automation system and method includes an infusion pump, an infusion pump and a remote processor. The remote processor is remote to the infusion pump and includes a controller interface and a controller, such that the controller bidirectionally communicates with the infusion pump, determines a current infusion state of the infusion pump and a current infusion pump user interface state and accepts a command to change the infusion state of the infusion pump from an external server. The controller determines if the command is consistent with the current infusion state of the infusion pump and the current infusion pump user interface state, executes the command if the command is able to be successfully executed, and confirms that the command is successfully executed.

  • Patent number: 9022983
    Abstract: An infusion pump includes a pump body for holding a roller clamp 7, and a roller movement mechanism 3 for moving a roller 72 of the roller clamp 7 and operating in coordination with manipulation of a door lock mechanism. When the door lock mechanism is in an unlocked state, an infusion tube T is blocked by the roller clamp 72. This configuration reliably prevents free flow even if a door is not closed completely or if the door is accidentally left unlocked. After the finish of infusion treatment, the infusion tube T is blocked by the roller clamp 7 at the moment when the door lock mechanism is unlocked before the opening of the door. This configuration avoids a trouble of removing the infusion tube T from the infusion pump while a user forgets to block the infusion tube by the roller clamp 7.

  • Patent number: 8974439
    Abstract: Some embodiments an infusion pump system can provide a suggested bolus dosage based on particular parameters (e.g., the user's recent blood glucose characteristics, food intake data, an amount of insulin already delivered to the user which has not yet acted on the user, or other factors). In some circumstances, the infusion pump system can receive information indicative of the user's blood glucose level and suggest an insulin bolus dosage that is at least partially dependent upon the recent rate of change in the user's blood glucose level. Such a feature can be helpful to a user when the infusion pump is operated in conjunction with a glucose monitoring device because the suggested bolus dosage can be at least partially based on recent data indicative of the user's blood glucose level.

  • Publication number: 20150065988
    Abstract: A pumping apparatus for use with a pump set to deliver fluid through the pump set to a subject includes a pumping device capable of acting on the pump set to produce a fluid flow within the pump set. A controller is in communication with the pumping device for controlling operation of the pumping device in a feeding configuration and in a flushing configuration. The controller is adapted to store a selected flow rate and a desired fluid volume of a first fluid in the memory and at least one of a flush rate and flush volume of a second fluid. A flush time compensator is capable of being run for determining a compensated feeding configuration of the first fluid based on an amount of time the controller will operate the pump device in the flushing configuration and the desired fluid volume of the first fluid.

  • Publication number: 20150057518
    Abstract: An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.
