| 20120125334 | HUMIDIFICATION SYSTEM - The present invention provides a method and apparatus for reducing condensed humidifying agent in a humidification system by pulsing a delivery of humidifying agent into a respiratory circuit. During a non-pulsed interval, gas flowing through the respiratory circuit will evaporate the condensed humidifying agent present in the respiratory circuit. The present invention also provides a method and apparatus for delivering humidified gas to a patient, wherein the delivery avoids the problems associated with a stationary water humidifier. In the method, the delivery of humidifying agent is precisely controlled to deliver a flow of humidifying agent to a volume of gas. | 05-24-2012 |
| 20120190997 | MAIN STREAM GAS ANALYZING DEVICE - A main stream gas analyzing device for measuring a concentration of a trace gas present in a gas stream and a method of measuring the concentration of the trace gas is disclosed. The main stream gas analyzing device includes a measuring chamber for receiving a gas flow, an infrared reflective material provided on an inner surface of the measuring chamber, an infrared radiation source directed toward the infrared reflective material of the measuring chamber and obliquely angled relative to a longitudinal axis of the measuring chamber such that infrared radiation being emitted from the infrared radiation source is reflected off of the infrared reflective material at least once, and an infrared radiation detector obliquely angled relative to the longitudinal axis of the measuring chamber to receive the reflected infrared radiation. | 07-26-2012 |
| 20120247479 | VALVING A RESPIRATORY GAS PATHWAY WITH A CATHETER BALLOON - A respiratory valve device includes a catheter balloon configured for being disposed in a respiratory gas pathway and valving the respiratory gas pathway. | 10-04-2012 |
| 20120247480 | FLOW SPLITTING NCPAP DEVICE - A nCPAP device includes an net configured for receiving a single gas jet flow. The single gas jet flow supplies gas for both nares. The device also includes a flow splitter configured for proportionally splitting said gas jet flow into two channels for the both nares according to one or more of nave anatomy and flow path resistance. | 10-04-2012 |
| 20120285455 | SMART CONNECTIONS - A mask for patient ventilation comprises a frame portion, a retention portion, and a connector portion. The frame portion is for surrounding a respiratory opening of a patient. The retention portion is for maintaining positive pressure between the frame portion and the patient. The connector portion is for connecting delivery tubes to the mask. The connector portion is configured such that the connector only couples with compatible components. | 11-15-2012 |
| 20120285461 | INTERCHANGEABLE INSERTS - In a mask for patient ventilation, a frame portion is included for surrounding a respiratory opening of a patient. A retention strap is coupled with the frame portion for maintaining positive pressure between the frame portion and the respiratory opening of the patient. A removable insert is configured to physically attach and detach from the frame portion without requiring removal of the frame or the retention strap from the patient. | 11-15-2012 |
| 20120285462 | LATERAL GAS LINE CONFIGURATION - A mask for patient ventilation comprises a frame portion, a front portion, a retention strap, and a gas delivery orifice. The frame portion is for surrounding a respiratory opening of a patient. The front portion is coupled with the frame portion and covers the respiratory opening region. The retention strap is for maintaining positive pressure between the frame portion and the patient. The gas delivery orifice is coupled with the frame portion and configured such that the gas delivery orifice is lateral to the front portion. | 11-15-2012 |
| 20120285463 | QUICK DONNING HEADGEAR - A patient interface for patient ventilation comprises a frame portion and a head strap system. The frame portion is for surrounding oral and nasal regions of a patient. The head strap system is configured for coupling from a left lateral portion of the patient interface, around a posterior skull of a patient, and to a right lateral portion of the frame portion such that in response to donning of the patient interface, the head strap system supplies a securing force to secure the frame portion in a position over nasal and oral cavities of the patient, the head strap is also configured to retain a head-shape when not in use to enable intuitive donning on the patient. | 11-15-2012 |
| 20120289838 | CARBON-DIOXIDE SAMPLING SYSTEM FOR ACCURATELY MONITORING CARBON DIOXIDE IN EXHALED BREATH - A carbon-dioxide sampling system for accurately monitoring carbon dioxide in exhaled breath. The system includes a ventilator. The ventilator is configured to ventilate a patient with respiratory gases. The ventilator includes a carbon-dioxide sampling control unit and a carbon-dioxide analyzer. The carbon-dioxide sampling control unit is configured to control the timing of sampling of carbon dioxide in the exhaled breath of a patient, and to control the timing of the analysis of exhaled gases by the carbon-dioxide analyzer. | 11-15-2012 |
| 20120289851 | CARBON-DIOXIDE SAMPLING DEVICE FOR NONINVASIVELY MEASURING CARBON DIOXIDE IN EXHALED BREATH - A carbon-dioxide sampling device for non-invasively measuring carbon dioxide in exhaled breath. The device includes a breath-sampling chamber and a carbon-dioxide collector. The breath-sampling chamber is configured to be disposed over a respiratory opening of a patient, and is also configured to seal with the patient's face preventing unintentional leakage of respiratory gases from the chamber. The carbon-dioxide collector is disposed in the breath-sampling chamber in fluid dynamic isolation from the respiratory gases. Moreover, the carbon-dioxide collector is configured to be disposed in proximity to, and outside of, the respiratory opening of the patient, and to collect a sample of exhaled breath from the patient. | 11-15-2012 |
