User interface and controls for a pump device
First Claim
1. A pump system, comprising:
- an infusion tubing for delivering a fluid;
a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing;
a heat exchanger cartridge in fluid communication with the infusion tubing and removably coupled to at least one thermal element for heating or cooling the fluid;
a central controller in electrical communication with the motor driven pump and the at least one thermal element; and
a user interface in electrical communication with the central controller, the user interface comprising a prime input and a bolus input;
wherein the central controller is configured to prime the infusion tubing by causing the motor driven pump to deliver the fluid through the infusion tubing in response to selection of the prime input and then, after priming the infusion tubing, to automatically deliver the fluid through the infusion tubing at a previously selected flow rate; and
wherein the central controller is configured to deliver the fluid by causing the motor driven pump to deliver a predetermined bolus volume of the fluid through the infusion tubing at a predetermined default bolus flow rate, or a user-selected bolus flow rate, in response to selection of the bolus input and then, after delivering the predetermined bolus volume, to automatically return to delivering the fluid through the infusion tubing at a previously selected flow rate or stop delivery of the fluid, according to a state of the pump prior to selection of the bolus input.

Abstract
A pump system selectably and dynamically controls the flow rate of a fluid being delivered to a patient'"'"'s body over a wide range of flow rates. The pump system includes an infusion tubing, a pumping mechanism, a motor drive assembly in mechanical communication with the pumping mechanism, a user input control, and an electronic controller in electrical communication with and at least partially controlling the motor drive assembly. The electronic controller include a digital signal processing controller in electrical communication with the motor drive assembly that is configured to receive a signal from the user input control and to cause power to be supplied to the motor drive assembly in response at least partially to the signal from the user input control. The pump system may selectably deliver fluid at rates from about 1 milliliter per hour to at least about 3000 milliliters per minute.

18. A pump system, comprising:
-
an infusion tubing for delivering a fluid; a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing; a heat exchanger cartridge in fluid communication with the infusion tubing and removably coupled to at least one thermal element for heating or cooling the fluid; a central controller in electrical communication with the motor driven pump and the at least one thermal element; and a user interface in electrical communication with the central controller, the user interface comprising a first maximum pressure input for selecting a first maximum pressure of the fluid; wherein the central controller is configured to automatically decrease a flow rate of the fluid upon detection of the first maximum pressure and then increase the flow rate of the fluid to a preselected flow rate unless the first maximum pressure is again detected. - View Dependent Claims (19)
