20120080034 | NON-INVASIVE BREATHING ASSISTANCE DEVICE WITH FLOW DIRECTOR - An nCPAP device for assisting patient breathing includes a generator body forming an inlet, a chamber, and first and second flow circuits. The chamber directs pressurized gas from the inlet to the flow circuits. The flow circuits each include a first and second jets, a flow director and an exhaust conduit. The jets emit a jetstream into the flow director in a direction of a patient side thereof. In some embodiments, the flow director forms a first tapered wall section directing inhaled air toward the patient and a second tapered wall section directing exhaled air toward the exhaust conduit. The generator body requires reduced driving pressures to achieve target CPAP levels and reduces total imposed WOB as compared to conventional designs. | 04-05-2012 |
20120285457 | NON-INVASIVE VENTILATION EXHAUST GAS VENTING - A non-invasive ventilation patient interface comprises a fresh gas entry port, an exhaust gas vent port, and a filter media disposed in the exhaust gas vent port. The fresh gas entry port is configured for coupling with a fresh gas supply. The exhaust gas vent port is configured for allowing expulsion of exhaust gas from the patient interface in response to exhalation of a patient. The filter media is configured for filtering contagious from the exhaust gas, diffusing the exhaust gas, and controlling an expulsion flow of the exhaust gas through the exhaust gas vent port. | 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 |
20120285464 | NON-INVASIVE VENTILATION FACIAL SKIN PROTECTION - A non-invasive ventilation patient interface comprises a fresh gas entry port, a frame, and a zygomatic facial interface. The fresh gas entry port is configured for coupling with a fresh gas supply. The frame is configured for coupling with a head strap system, wherein the head strap system is configured for supplying a securing force to secure the patient interface in a position over a respiratory opening of a patient. The zygomatic facial interface is coupled with the frame and configured for spreading the securing force away from a nasal bridge of the patient and onto left and right zygomatic arch regions of the patient. | 11-15-2012 |
20120285465 | NON-INVASIVE VENTILATION FACIAL SKIN PROTECTION - A non-invasive ventilation patient interface comprises a fresh gas entry port, an exhaust gas entry port, and a facial skin interface. Fresh gas entry port is configured for coupling with a fresh gas supply. The exhaust gas vent port is configured for allowing expulsion of exhaust gas from the patient interface. The facial skin interface is configured for eliminating fluid from within the patient interface and for eliminating fluid from facial skin which is covered by the patient interface. | 11-15-2012 |
20120285466 | ADJUSTING A VENTILATION MASK - In a method for adjusting a ventilation mask, a ventilative state is measured of a ventilation mask that is placed over a respiratory opening of a patient A sealing portion of the ventilation mask is for establishing a fluid seal between the ventilation mask and the patient. The sealing portion comprises a plurality of bladders. An unintentional leak of the fluid seal is determined based on a measured change of the ventilative state. A bladder of the plurality of bladders is adjusted to seal the unintentional leak. | 11-15-2012 |
20120285467 | CORRUGATED FLEXIBLE SEAL OF A VENTILATION MASK - A ventilation mask comprises a corrugated flexible seal, and a plurality of ridges disposed along the corrugated flexible seal. The corrugated flexible seal is configured for establishing a fluid seal between the ventilation mask and a patient, and for allowing facial movements of the patient while maintaining the fluid seal. The plurality of ridges disposed along the corrugated flexible seal is configured for physical contact with the patient. | 11-15-2012 |
20130284167 | PATIENT NASAL INTERFACE FOR USE WITH A NASAL AIRWAY PRESSURE SYSTEM - A patient nasal interface is provided that includes a female portion and a first registration feature. The female portion receives a male portion of a generator head. The female portion wraps around and over the male portion when the male portion is inserted into the female portion of the patient nasal interface. The first registration feature is configured for mating with a second registration feature associated with the male portion of the generator head and wherein the mating of the first registration feature with the second registration feature provides a feedback to an operator upon proper insertion of the male portion into the female portion. | 10-31-2013 |
20130284170 | SOUND-REDUCING TUBING IN A RESPIRATORY GAS DELIVERY SYSTEM - A system for reducing sound level in a respiratory gas delivery system is described. The system includes a first portion of a breathing circuit tubing and a second portion of the breathing circuit tubing positioned in-line with the first portion, wherein the second portion of the breathing circuit tubing is a sound-reducing tubing. | 10-31-2013 |
20130319413 | REDUCING SOUND LEVEL IN A RESPIRATORY GAS DELIVERY SYSTEM - A system for reducing sound level in a respiratory gas delivery system is described. The system includes an exhaust portion and a sound reducing component that is coupled with the exhaust portion and is configured for absorbing sound. The sound reducing component includes a pathway through which air from within the exhaust portion may move. | 12-05-2013 |
