摘要： A medical breathing gas delivery system design employs a manifold delivering gas in a controlled fashion to patients which includes two inhaled gas one-way valves, at least one pressure sensor for patient airway pressure monitoring, and one controlled exhalation pressure proportional control valve which may be overridden by patient exhaled pressure or if there is a power loss. The manifold is connected to a controlled source of breathing gas which may, for example, be a variable-speed fan, or a pressure-based gas flow controller with dynamic self-calibration employing a fast-acting valve and a pressure sensor, either of which yield predictable gas flow control with a minimum of components. The manifold exhalation pressure control valve and gas flow source may, for example, be controlled with a computer system which adjusts the valve power waveforms to attain the time-varying flow and pressure curves required by clinicians, then stores and displays the waveforms to enable long-term trend monitoring and alarm generation. Accurate gas mixing using the pressure-based gas flow control yields automatically calibrated mixes which are of use for patients in, for example, intensive care ventilation and in anesthesia machines for operating rooms.

摘要： Systems and related methods for delivering hot air to a respiratory tract of a user. The system includes a hot air source comprising a heater and a blower configured to produce a flow of hot air have a temperature of at least 150° F. The flow of hot air may have a relative humidity of less than 50-20%. The system also includes a user interface connected to the hot air source by a breathing tube. The user interface is configured to receive the flow of hot air from the hot air source and deliver the flow of hot air to the respiratory tract of the user.

摘要： Filter made entirely with natural and biodegradable materials, for the protection of the respiratory tract of patients in the medical-surgical field and process for making it. The filter has a porosity or 80-98% and pore diameters of 100-350 micrometers and the pores have a shape of channels open at the ends, which are parallel to each other. The filter is obtained by preparing an aqueous solution of chitosan and an aqueous solution of gelatin, mixing them, pouring it into a container, keeping the container closed until obtaining a hydrogel and freeze-drying. A cross-linking step takes place by (a) adding a chemical cross-linker to the mixture of the chitosan and gelatine solutions and cross-linking before freeze-drying, or (b) subjecting the freeze-drying product to a thermal dehydration treatment.

摘要： A first source of medical gas has a generally cylindrical male outlet with a cylindrical bore and a threaded outer cylindrical surface. A flexible cylindrical elastomeric medical gas tubing has an input end with a bushing making a flush abutment with the male outlet at the output orifice. An output end attaches to any of a plurality of medical gas utilizing devices, but preferably with a dampening disperser held in position in the space in the vicinity of a patient's nose and mouth. An annular flange of the input end bushing resides within a central cylindrical bored out region extending through the first end and nearly to the second end of a rotatable connector forming an interior surface of a connector with threads coupling with the threads of the male outlet. The second end is an annular abutment against the annular flange holding the input end tubing bushing against the outlet source and providing an airtight coupling. A gripping means is on the exterior surface of the connector.
