| Number | Title | Issue Date |
| 5540220 | Pressure-limited, time-cycled pulmonary ventilation with volume-cycle override A pressure-limited, time-cycled pulmonary ventilator includes a pressurized gas system that supplies respiratory gas to a patient at a selected inspiratory flow rate; an exhalation valve that (a) opens an expiratory flow path in response to the elapsing o... | 07/30/1996 |
| 5460039 | Flow sensor system A system for measuring the flow rate of gas includes a flow head having a sensor thermoresistor mounted transversely to the flow of gas, and a reference thermoresistor mounted parallel to the flow of gas, both thermoresistors having equal resistance versu... | 10/24/1995 |
| 5331995 | Flow control system for medical ventilator A system including the method employed, for controlling the flow of a pressurized gas through a variable orifice flow control valve in a pressurized gas conduit system, such as a ventilator, in response to either a desired flow rate/volume input signal, a... | 07/26/1994 |
| 5263369 | Flow sensor system and method A gas flow sensor system, using hot wire flow and temperature sensors, compensates and corrects for various factors, such as water vapor content and gas composition in the measured gas, gas temperature, physical differences in the sensors, ambient atmosph... | 11/23/1993 |
| 5107831 | Ventilator control system using sensed inspiratory flow rate A ventilator control system is responsive to a flow rate signal from a flow rate sensor that senses the flow rate of gas to a ventilated patient. The ventilator control system provides an episode signal to a ventilator to actuate the ventilator to provide... | 04/28/1992 |
| 5069220 | Measurement of gas concentration in exhaled breath A method for analyzing the concentration of selected constituent gases in the expiratory gas streams from a patient. The method includes the steps of: (a) measuring the flow rate of the expiratory gas stream to provide a flow rate signal; (b) generating a... | 12/03/1991 |
| 4702240 | Demand-responsive gas blending system for medical ventilator A gas blending system for use with a medical ventilator blends a pressurized gas with ambient air for delivery to the ventilator in response to the ventilator's demand for gas during the gas intake phase of its cycle. The system comprises a demand valve t... | 10/27/1987 |
| 4621632 | Humidifier system A humidifier system including a humidifier chamber and heater assembly, microprocessor based control circuitry, and a housing for the control circuitry. The humidifier system is adapted to provide air at nearly 100 percent relative humidity and at a prede... | 11/11/1986 |
| 4602653 | Electronically-controlled gas blending system A gas blending system includes a proportional mixing valve having a valve element movable between first and second limits of travel corresponding to a minimum and maximum percentage, respectively, of one of the gases in the blended mixture. The position o... | 07/29/1986 |
| 4527557 | Medical ventilator system A volume ventilator is disclosed which has a balloon valve type exhalation valve for permitting release of gases to the ambient environment during the exhalation period of artificial ventilation or spontaneous breathing, or when there is excess proximal p... | 07/09/1985 |
| 4494252 | Laryngeal prosthesis An external, self-contained laryngeal prosthesis is adapted for use by a tracheostomized patient having a surgically-formed "pseudoglottis" separating the trachea and the hypopharynx. The prosthesis includes a housing and a fitting for attaching the housi... | 01/22/1985 |
| 4489440 | Pressure-compensated pneumatic speech simulator A pneumatic speech simulator has a vibratory tone-generating element which produces an audible tone in response to the flow of pressurized air within a predetermined pressure range, said tone being transmitted to a patient's pharyngeal region by a conduit... | 12/18/1984 |
| 4476707 | Gas flow measurement with detented chopper valve A gas flow measuring system employs an oscillating chopper valve alternately to deliver a flow head-generated pressure and a reference pressure to a pressure transducer. The chopper valve is driven by a stepping motor under the control of a microcomputer.... | 10/16/1984 |
| 4417573 | Patient adaptor for medical ventilator A patient adaptor fitting for a medical ventilator includes a jet pump having a nozzle receiving breathing gas from the inspiratory leg of the patient circuit, and a throat in communication with the expiratory leg of the patient circuit. Gas flows from th... | 11/29/1983 |
