A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient includes a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the respiratory gas is controlled by a microprocessor, a mixing area for mixing a first gas and a second gas in the respiratory gas flow pathway, a humidification area downstream of the mixing area and configured for humidifying respiratory gas in the respiratory gas flow pathway, and a heated delivery conduit for minimizing condensation of humidified respiratory gas.

A ventilator, for the automated ventilation of a patient, includes a breathing gas delivery unit, at least one volume flow sensor for detecting a volume flow of the breathing gas, at least one breathing gas sensor for detecting a carbon dioxide concentration in the breathing gas, at least one pressure sensor for detecting a pressure of the breathing gas, as well as at least one computer. The computer is configured to actuate the breathing gas delivery unit as a function of the detected pressure and of a preset desired pressure value. The computer is further configured to perform an adaptation of the desired pressure value and an adaptation of a ventilation rate as a function of the detected volume flow and as a function of the detected carbon dioxide concentration.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.

A passive oxygen mask and vacuum regulation system disposed in fluid communication with a vacuum scavenging array includes a passive oxygen mask dimensioned to fit over a patient's nose and mouth and having a gas inlet port and an expired gas outlet port. A vacuum regulation assembly has a vacuum regulator which includes an expired gas discharge tube disposed in fluid communication between the passive oxygen mask and the vacuum regulation assembly, and a vacuum suction tube disposed in fluid communication between the vacuum regulation assembly and the vacuum scavenging array. The vacuum regulation assembly further comprising a vacuum attenuation port through a portion of a regulator housing, wherein the vacuum attenuation port is at least partially defined by an attenuation port diameter dimensioned to reduce a vacuum suction pressure in the expired gas discharge tube to a predetermined vacuum suction pressure.

To provide a mask capable of reducing a load of a patient while suppressing lowering of accuracy at which a subject's exhaled air is measured. A mask to be put on a subject's face includes a mask body portion demarcating an internal space in a state of covering part of the subject's face and a cup-shaped nasal cup covering a subject's nose in a state of being arranged inside the internal space, in which the nasal cup includes a first wall portion covering the subject's nose, a second wall portion arranged under the subject's nostrils, and an exhaled air discharge portion guiding an exhaled air from the subject's nose to an exhaled air sensor, and at least part of the exhaled air from the subject's nose is guided toward the exhaled air discharge portion by the second guide portion in a state where the nasal cup covers the subject's nose.

Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

An adapter (1) for establishes a flow channel (2) between a breathing gas supply and a patient connection piece. A set (20) and a system (30) for ventilation or respiratory support, each include the adapter (1). The adapter (1) includes a first connection structure (3) configured to connect to the breathing gas supply and a second connection structure (4) configured to connect to a patient connection piece. A bypass channel (5) branches off from the flow channel (2) and is provided with an extraction opening (7) which can be closed at least temporarily by a safety valve (6). The safety valve (6) is configured such that the extraction opening (7) is closed when a ventilation pressure prevailing in the flow channel (2) is lower than a pressure prevailing on a side of the safety valve facing away from the flow channel (2).

A medical double configurational and multiple ports mask preferably including a multifunctional plug with or without a nebulizer oxygen delivery adaptor (“NODA”) attachment. The mask fits over the mouth and the nose and preferably contains at least two possible nose/face configurational solutions. The mask can be secured over the head with a stretchable or non-stretchable material. The position of the preferred triple ports of the double configurational mask provides improved structural construction reflecting different patient's nose/face features and allows for different types of procedures to be performed at the same time regardless of the patient's head/neck position. The multifunctional plug can be used for a variety of applications. The mask can be used with existing standardized disposable respiratory care equipment, including a simplified improved nebulizer oxygen adaptor (“SINODA”) and/or multifunctional use nebulizer oxygen delivery adaptor (“MUNODA”) attachment.

The present invention provides an improved percutaneous dilation tracheostomy device. The device is configured to include all of the required components to perform a percutaneous tracheotomy. The device includes a retractable needle and an extendable j-wire rather than having separate components as in typical percutaneous tracheostomy devices. The device includes a dilator section to expand the diameter of a patient's stoma. The device is further configured to allow an operator to perform a bubble test to alert the user that the tube is in the trachea. In addition, the device is generally more compact than typical emergency tracheostomy devices.

In one embodiment, the present invention provides a system to deliver at least one therapeutic gas to a spontaneously breathing patient, wherein the rate of delivery of the at least one therapeutic gas exceeds the patient's inspiratory flow rate, and the amount of the at least one therapeutic gas that is wasted is minimized or eliminated.
