In one embodiment, a filter assembly for use in an insufflation system is described. The filter assembly comprises: a filter medium operative to filter medical gases; a housing comprising an inlet, an outlet and the filter medium, the housing defining a gases flow path through the filter medium between the inlet and the outlet; and at least one heating element being positioned in the housing and being configured to heat the filter medium; and wherein, the at least one heating element is spaced apart from the filter medium and from an inner surface of the housing.

This disclosure describes systems and methods for humidifying ventilator delivered breathing gases. These systems and methods utilize a hollow cone atomizer (e.g., a pressure swirl atomizer) and/or a heating element associated with a heating circuit and/or a heating tube. In some aspect, the systems and methods utilize received flow, temperature, and/or humidity information to determine an amount of water to add to breathing gases to reach a desired humidity of the breathing gases delivered to the patient. In further aspects, the humidification system can serve as a nebulization system for delivering nebulized medicine.

A respiratory assistance apparatus is configured to provide a heated and humidified glow of gases and has a control system that is configured to detect a fault in the flow path. A flow path is provided for a gases stream through the apparatus from a gas inlet through a blower unit and humidification unit to a gases outlet. A flow rate sensor is provided in the flow path and is configured to sense the flow rate and generate an flow rate signal and/or a motor speed sensor is provided that is configured to sense the motor speed of the blower unit and generate an indicative motor speed signal.

Provided is an integrated monitoring and management system for endoscopic surgery, in which the system simultaneously monitors and manages the surgical environment such as pressure, temperature, humidity, smoke, and the like inside the human body, and the type and access of surgical instruments used for surgery throughout the surgical procedure at the time of endoscopic surgery, such that an optimal surgical environment is maintained according to a monitoring result, and when an accident occurrence factor is monitored during the surgical procedure, it is possible to prevent an accident from occurring by informing of the accident occurrence factor, and it is possible to quantify a safe and successful surgical procedure by analyzing accumulated big data.

A device (102) provides respiratory treatment for SDB (including mild OSA) and other respiratory conditions. A flow generator warms and humidifies gas at controlled flow levels. For example, the device (102) delivers breathable gas to the upper airway at flow rates of about 10-35 Liters/minute. Levels of flow rate, temperature and/or humidification of the device may be automatically adjusted in response to the detection of SDB events. The device may also automatically deliver adjustments of any of the levels in accordance with detected phases of respiratory cycles. In some embodiments, the device automatically delivers distinct levels to either of the nares based on independent control of flow to each nare. A warm-up procedure controls temperature and humidity at a desired target during a ramp-up of flow to the set therapy level. A cool-down procedure controls temperature above the dewpoint to avoid condensation internal to the device and patient interface.

Disclosed are methods, systems, and devices for providing a personalized humidification level. A control system receives, from a first sensor, one or more environmental parameters regarding conditions of the environment. The control system receives, from a second sensor, one or more physiological parameters associated with a user within the environment. The control system determines an action associated with a desired change in the humidity within the environment based, at least in part, on the one or more environmental parameters and the one or more physiological parameters. The control system causes, at least in part, a performance of the action associated with the change in the humidity in the environment based, at least in part, on moisture outputted by a humidifier module. The methods and devices perform the same functionality as the control system.

A system and method to match an interface to the face of a user for respiratory therapy. A facial image of the user is stored. Facial features based on the facial image are determined. A database stores facial profiles based on facial features and a corresponding plurality of interfaces. A database stores operational data of respiratory therapy devices with the plurality of corresponding interfaces. A selection engine is coupled to the databases. The selection engine is operative to select an interface for the user from the plurality of corresponding interfaces based on a desired outcome based on the stored operational data and the facial features. The collected data may also be employed to determine whether the selected interface is correctly fitted to the face of the user.

A respiratory or surgical humidifier comprising a heater base and an electrical connector. The heater base is configured to receive a humidifier chamber and supply humidified gases to a breathing tube when coupled with the chamber. The heater base also comprises a control circuit. The electrical connector is provided for electrically coupling the control circuit to a breathing tube. The electrical connector comprises a first power line, a second power line, and a data line configured to allow serial communication between the control circuit and one or more digital devices. Also provided is a humidifier system, a breathing tube, a humidifier chamber and an electrical connector for a humidifier.

The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.
