A disposable, isolating intubation device is described, the device comprising a flexible, spherical compartment inflatable from a collapsible state, the flexible, spherical compartment being substantially transparent and having a closed end and an open end distal from the closed end defining an inside volume for receiving a head, shoulders and a portion of a torso of a patient and methods of using.

Provided is a filtering facepiece respirator. The respirator includes a mask body having an anterior side portion, a posterior side portion, a middle portion, a first side portion, a second side portion, a top side portion, a bottom side portion and outer edge portions. The respirator further includes a primary port positioned at the anterior middle portion of the mask body and a detachable primary port adapter which is positioned over and engages the primary port. The respirator may further include an oxygen port and oxygen port adapter and a luer port and luer port adapter.

A ventilator is provided that dynamical adjusts the pressure, flow, and volume of the delivered gas to a patient as the condition of the patient changes. The ventilator adjusts the flow and mixing of gases through flow control valves. The ventilator includes at least two banks of valves, each bank having a plurality of valves, where each valve in the bank has a specific orifice size that is different from at least one other valve in the respective bank of valves. In one example, the ventilator further includes an exhalation valve assembly having an exhalation valve housing and exhalation valve base coupled together to retain a flexible exhalation tube. The exhalation valve assembly including at least two pistons extending at least partially through the exhalation valve assembly to contact the exhalation tube and, when actuated, impart pressure on the walls of flexible exhalation tube to restrict or completely close the flow of air through the flexible exhalation tube.

A protective headgear includes a main body (e.g., face mask) that is worn over the face. The main body has an inhalation port that is for fluid coupling to an inhalation gas source and at least one exhalation port. The headgear includes an HME unit that has an inhalation leg that is in fluid communication with the inhalation port and a top leg that is in fluid communication with the inhalation leg and the at least one exhalation port. The top leg has an open window formed therein. The HME unit further includes an HME membrane that is disposed within the top leg adjacent the open window such that the HME membrane completely covers the open window.

A disinfection application, particularly, to a device capable of disinfecting a ventilator as well as a face mask and a hose, and more particularly, to an ozone disinfection device, an ozone disinfection system, and an ozone disinfection method. The ozone disinfection device includes: a sealed disinfection space, a gas distribution unit, an ozone generation unit, a suction pump, a filter, and a control module.

A patient interface for delivery of gas to a patient comprises at least one inspiratory element for directing a flow of gas to a patient airway, at least one expiratory element comprising an expiratory gas flow path for directing expiratory gases from the patient; and at least one gas permeable body in the expiratory gas flow path. Each inspiratory element comprises at least one inspiratory lumen through which said flow of gas is directed. The gas permeable body is configured such that expiratory gases in the expiratory gas flow path are directed through the gas permeable body before exiting the patient interface.

A face shield, patient interface and methods of use thereof are described for improved respiratory therapy of patients. In particular, a face shield is disclosed that acts as a seal when used with a patient interface. The face shield may be manufactured from a low melt temperature hard thermoplastic material. The face shield may be formed initially formed to match the general contours of the face, but not customised to a specific user's face. The face shield may be crosslinked to provide shape memory to the seal and to improve its handling properties and is configured to be thermoformed to a user's face. The face shield may be customised to the patient's facial features to a second customised shape.

Provided are an anesthesia respiration apparatus, an anesthesia respiration gas path system, and an anesthetic gas path system, to exhibit a novel anesthesia respiration structure. In this structure, some channels are provided in an anesthesia main machine, and no long external pipeline or only a small number of long pipelines are required to meet demands of gas path connection, thereby reducing various potential safety hazards and inconvenience caused by excessive exposed long pipelines.

A patient interface (1) is for aerosol treatment, having a base (2) to surround the patients mouth and nose and engage the skin with a resilient seal, and with a strap (8) to attach to a patients head. There is a support (3) on and across the base for supporting an aerosol delivery head with prongs (4, 5). An enclosed volume is formed in the interface by attachment of a shell (10), which has an extraction port (11) for attachment of an extraction system (20) to extract gas from this volume. An HFNT system includes a patient interface surrounding the nose and mouth and an aerosol delivery apparatus (4, 6), an extraction apparatus (20), and a controller (100) to control delivery of aerosol and/or gas to the interface and to extract gases from a volume enclosed by the interface. Because of the fully sealed volume within the interface there are a wide range of control scenarios possible, using pressure sensing in the volume, bypass valves (201), dynamically-controllable nebulizer (203).

Provided in embodiments of the disclosure is a medical alarm system, including an anesthesia device, a weigher and a waste gas adsorption canister, wherein the waste gas adsorption canister is connected to the anesthesia device; the anesthesia device is in mutual communication with the weigher; the anesthesia device is configured with a first alarm apparatus thereon, wherein the anesthesia device is configured to release an anesthetic gas and discharge a waste anesthetic gas; the waste gas adsorption canister is configured to adsorb the waste anesthetic gas; the weigher is configured to acquire weight data of the waste gas adsorption canister by weighing in real time and transmit the weight data to the anesthesia device; the anesthesia device is configured to determine whether to trigger an alarm based on the weight data and at least one preset alarm threshold, and output at least one alarm prompt of sound, flashing light and an interface prompt by the first alarm apparatus upon determining to trigger an alarm, wherein the at least one preset alarm threshold is a data criterion for an adsorption capacity abnormality of the waste gas adsorption canister or a data abnormality of the weigher. The intelligence and safety of the medical alarm system can be improved by the embodiments of the disclosure.
