Patent number: 7252637Abstract: A method of screening for possible onset of sepsis in a patient includes providing the patient with a transducer that automatically and periodically measures a first physiological parameter of the patient and transmits a first signal that is encoded with the measured parameter value, and receiving the first signal and automatically comparing the measured parameter value with at least one alarm limit. The first physiological parameter is body temperature, heart rate, respiration rate or a clinical indicator of sepsis. A conditional warning signal is asserted in the event that the measured parameter value bears a predetermined relationship to said alarm limit and an alarm signal is issued in the event that a physiological condition other than the condition that gave rise to the conditional warning signal is indicative of onset of sepsis.Type: GrantFiled: February 17, 2006Date of Patent: August 7, 2007Assignee: Mini-Mitter Co., Ltd.Inventors: Dennis M. Ebner, Jack E. McKenzie

Patent number: 7250777Abstract: A device for measuring a resistance includes a comparator. A D-type flip-flop has its D input connected to the output of the comparator and its latch input connected for receiving a pulse signal at a fixed pulse repetition rate. A reference voltage source is connected to a first of the inputs of the comparator and an integrator is coupled between an output of the flip-flop and the second of the two inputs of the comparator. The integrator includes a resistor whereby the integrator develops a voltage at the second input of the comparator that depends on the pulse repetition rate and on the resistance of the resistor. The comparator, the integrator and the flip-flop are connected in a negative feedback loop such that at steady state the voltage developed by the integrator at the second input of the comparator is substantially equal to the reference voltage.Type: GrantFiled: March 28, 2006Date of Patent: July 31, 2007Assignee: Mini-Mitter Co., Inc.Inventors: Rick Allen Kobbe, Florian G. Bell, Donna K. Barton

Patent number: 7165547Abstract: A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.Type: GrantFiled: May 12, 2003Date of Patent: January 23, 2007Assignee: RIC Investments, LLCInventors: Patrick W. Truitt, William A. Truschel, Bernie F. Hete, Michael Bobeck, Michael W. Haas

Patent number: 7119712Abstract: A telemetry system includes a transmitter unit that measures a first value of a parameter, incorporates the first value in a first data packet and transmits the first data packet, and measures a second value of the parameter, incorporates the second value and the first value in a second data packet and transmits the second data packet. A receiver unit periodically receives a signal and generates a sequence of bits therefrom, determines whether the sequence of bits includes a payload that meets a predetermined standard and, if so, recovers a more recent datum from the payload else enters a data recovery mode. In the data recovery mode, the receiver unit receives a transmission signal and generates a second sequence of bits and determines whether the second sequence of bits contains a payload that meets the predetermined standard and, if so, recovers both a more recent datum and a less recent datum from the payload.Type: GrantFiled: September 19, 2003Date of Patent: October 10, 2006Assignee: Mini-Mitter Company, Inc.Inventor: Rick Allen Kobbe
