The application discloses a new medical application of a noninvasive ventilator, in particular to a new application of the noninvasive ventilator for improving, relieving or treating human body gastroesophageal reflux related discomfort symptoms. The discomfort symptoms include but are not limited to stomach distension, abdominal distension, acid reflux, heartburn, retrosternal discomfort, night reflux, throat reflux discomfort and the like. The application firstly finds that the airway positive pressure generated by the conventional noninvasive ventilation can effectively improve the stomach distension and gastroesophageal reflux series symptoms which have long plagued the public through the physiological mechanisms of improving human body respiratory mechanics, adjusting the chest and abdominal pressure balance, reducing the diaphragm abnormal lifting and reducing the intragastric pressure. The application expands a new clinical application scene of the noninvasive ventilator, and the application is safe, noninvasive and long-term home use, the effect is stable, and has definite medical application value and popularization prospect.

An embodiment provides a non-invasive ventilation patient interface. In one example, the patient interface includes a conduit having an entrainment opening and a nasal opening. The patient interface includes an orifice proximate to the entrainment opening and configured to expel a jet of gas and a surface having a first end and a second end, the first end being proximate to the orifice and extending substantially parallel to a flow direction of the jet of gas expelled from the orifice, the second end being closer to the nasal opening than the first end. In an operational state, the jet of gas adheres to the surface via Coanda effect, thereby entraining ambient air into the entrainment opening to deliver the jet of gas and the ambient air through the nasal opening of the conduit.

An embodiment provides a system having a non-invasive ventilation patient interface. In one example, the system includes a headgear element and a non-invasive ventilation patient interface detachably coupled to the headgear element. The non-invasive ventilation patient interface includes a conduit having an entrainment opening and a nasal opening disposed along a conduit axis. A pressure sensing element is provided proximate to the nasal opening. One or more orifices proximate to the entrainment opening are configured to expel a jet of gas. One or more surfaces have a first end and a second end, with the first end being proximate to the one or more orifices and directing a flow of the jet of gas expelled from the one or more orifices, the second end being closer to the nasal opening than the first end. In an operational state, the jet of gas adheres to the one or more surfaces via the Coanda effect, thereby entraining ambient air into the entrainment opening to deliver the jet of gas and the ambient air through the nasal opening of the conduit.

The invention discloses an automatic telescopic child stomach tube device capable of preventing abdominal distension and regurgitation under noninvasive ventilation. The device is used for preventing abdominal distension of a child patient under noninvasive ventilation. A nasal gastrointestinal tube head, a controller, an automatic breathing machine airflow blocker, a stomach tube body and a supporting strip form a whole, the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube, in the process of using the stomach tube, medical workers place the stomach tube with the automatic breathing machine airflow blocker into the stomach through the esophagus of a child patient, and the stomach tube with the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube. After the controller is pressed down, the airflow blocker of the automatic breathing machine fills the gap between the stomach tube and the esophagus, the situation that airflow enters the stomach through the esophagus to cause abdominal distension of a child patient in the application process of the non-invasive breathing machine is avoided, meanwhile, the influence of gastric regurgitation on the child patient is prevented, and therefore the situation that feeding of the child patient is affected by non-invasive ventilation is prevented.

A patient ventilation interface has a throat body defining a venturi throat open to ambient air, a nasal pillow disposed about the venturi throat to define a plenum chamber between the venturi throat and the nasal pillow, a nozzle arranged to output ventilation gas to the venturi throat, and a pressure sensing tube having a pressure sensing port positioned in fluid communication with the plenum chamber. The nasal pillow is an integral part of the throat body. An expected error in a sensed patient airway pressure P sense and a nozzle flow rate V' n of the nozzle can be corrected by applying a correction factor P delta indexed to the sensed patient airway pressure P sense . Delivery of ventilation gas output by the nozzle can be controlled in response to the corrected patient airway pressure.

The invention relates to a patient ventilation or breathing device and components therefore for use in all forms of respiratory apparatus ventilation systems including invasive and non-invasive ventilation, positive airway pressure therapy, Continuous Positive Airway Pressure (CPAP), and particularly Bi-Level therapy and treatment for sleep disordered breathing (SDB) conditions such as Obstructive Sleep Apnea (OSA), and for various other respiratory disorders and diseases. The invention particularly relates to a blower, to a blade, to a gasket, to a cable, to an impeller, to a gas inlet and inlet member, to an improved air path or fluid flow path and components thereof, and / or to a modular ventilation or breathing device as referred to above and particularly incorporating one or more of the other aspects of the invention.

The invention relates to a noninvasive ventilation and thermal stimulation coordinated time sequence scheduling and safety interlocking method, which comprises the following steps of: when a system is powered on or reset, closing thermal stimulation output, setting a prohibition mark and invalidating a control right token; and collecting and updating the ventilation state according to a preset period, wherein the state information at least comprises a stable sign and an alarm sign. The thermal stimulus output state may be altered only when the token is valid. And when the stable mark is true, the alarm mark is false and the prohibition mark is not set, executing token handover: initiating an application, receiving a grant and feeding back confirmation, and enabling the token to take effect after the confirmation is completed. And if the alarm sign is true or the stable sign is false, a prohibition sign is immediately set, so that the token is invalid and thermal stimulation output is closed. During the setting period of the forbidding mark, forbidding the change of the thermal stimulation output state; and after a preset condition that the stable sign is true and the alarm sign is false is satisfied, the prohibition sign is cleared, the token handover process is allowed to be executed again, and cooperative control and safety protection are realized.

The method specifically comprises the following steps: step 1, anesthesia and body position fixation; step 2, non-invasive ventilation support; step 3, performing surgical approach and exposure; step 4, fine dissociation of the pulmonary door structure; step 5, implanting a graft; and 6, closing the chest and resuscitating. Airway injury, postoperative infection and respirator-related lung injury caused by traditional tracheal intubation are thoroughly avoided, oxygen saturation in a rat operation is kept in a stable state through high-flow heating and humidifying oxygen inhalation and left-side clinostatism protection on the opposite lung, the death rate in the operation is greatly reduced, the pulmonary alveoli structure after lung transplantation is complete and free of inflammation infiltration, and the lung transplantation effect is good. The accuracy of research data is obviously improved, and the physiological status is better fit.
