Patent number: 9498586Abstract: An infusion pump system including an infusion tubing for delivering a fluid, 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 motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing and the heat exchanger cartridge, and a central controller in electrical communication with the motor driven pump and the at least one thermal element. The central controller is configured to selectively deliver the fluid to a patient without heating or cooling the fluid by causing the motor driven pump to pump the fluid through the infusion tubing and the heat exchanger cartridge while the thermal element is off.Type: GrantFiled: June 30, 2014Date of Patent: November 22, 2016Assignee: SMISSON-CARTLEDGE BIOMEDICAL LLCInventors: Hugh F. Smisson, III, Richard G. Cartledge, David C. Field, Harvey A. Lewis, Jr., Frederick J. York

Patent number: 8764408Abstract: 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.Type: GrantFiled: January 25, 2013Date of Patent: July 1, 2014Assignee: Smisson-Cartledge Biomedical LLCInventors: Hugh F.

Patent number: 7896834Abstract: A pump system selectably controls the temperature, flow rate, flow volume, and flow pressure of a fluid being infused into a patient's body. The pump system includes a cartridge and components that removably connect with a pump housing and corresponding components, providing simple attachment of the cartridge to the pump housing. The pump housing includes a pressure sensor, a bubble detector, and a temperature sensor on a first side of the pump housing, and an engaging actuator and a central controller. The cartridge includes on a first side a heat exchanger, a pressure receptor correspondingly aligned with the pressure sensor, and a detector interface correspondingly aligned with the bubble detector and temperature sensor. Upon aligning the cartridge with the pump housing and actuating the engaging actuator, the pressure receptor communicates with the pressure sensor and the detector interface aligns with the bubble detector and temperature sensor.Type: GrantFiled: August 7, 2007Date of Patent: March 1, 2011Assignee: Smisson-Cartledge Biomedical LLCInventors: Hugh F. Smisson, III, Richard G. Cartledge, David C. Field, William J. Jaecklein, Michael L. Koltz, Harvey A. Lewis, Jr., Bradford J. Rainier, Roland T. Stafford
