Disclosed is a fluid trap for use with, or comprising part of, a respiratory therapy system, d particular comprising part of, or configured to be connected to, a breathing limb, such as an expiratory limb, of a respiratory therapy system. The fluid trap comprises a container configured to contain fluid received from an inlet; a closure, the closure and container being configured to be removeably mounted together to close the container; and a valve configured to be removeably mounted on at least one of the container and the closure, and configured to be in a closed condition which prevents fluid from flowing through the inlet when the closure is not mounted on the container, the valve being further configured to be in an open position which allows fluid from the inlet into the container when the closure is mounted on the container.

A pathogen detection system includes a pathogen sensing adaptor that detect pathogens present in the breathing circuit associated with a ventilated patient. A pathogen sensing adaptor may include a conduit, removable cartridges with testing strips, an optical sensor, and communication circuitry. Upon detecting a colorimetric change on the testing strip, the optical sensor generates a signal indicative of the presence and/or level of pathogens.

A transportable extracorporeal system includes a housing, a blood flow inlet, a blood flow outlet, a plurality of hollow gas permeable fibers, a gas inlet in fluid connection with inlets of the plurality of hollow gas permeable fibers, a gas outlet in fluid connection with outlets of the plurality of hollow gas permeable fibers, a first moving element, a concentrated oxygen generating device, a second moving element, a hollow transport conduit having a proximal opening and a distal opening and a power source configured to provide power to the first and second moving elements. The plurality of hollow gas permeable fibers comprising a gas transfer membrane. The concentrated oxygen generating device is configured to recycle waste oxygen from the gas transfer membrane to increase throughput and remove, by an adsorption/desorption process, unwanted gasses.

A process (10), with a computer program, a device (30) and a ventilation system (40) detect a leak in a patient gas module, which suctions and analyzes a continuous sample gas stream from a ventilated patient (20), in a ventilation system for ventilating a patient (20). The process includes a determination (12) of a first time curve of a carbon dioxide concentration in a breathing gas mixture of the patient (20) and the determination (14) of a second time curve of a concentration of another gas in the breathing gas mixture, which gas is different from carbon dioxide. The process (10) further includes a determination (16) of a statistical similarity indicator between the first time curve and the second time curve and the detection (18) of the leak based on the similarity indicator.

An expiratory limb is provided that is configured to remove humidified gases from a patient and configured to provide improved drying performance by providing a tailored temperature profile along the limb. Limbs for providing humidified gases to and/or removing humidified gases from a patient are also provided, the limbs having improved gas residence time at constant volumetric flow rate. The improved residence time can be achieved by providing a limb comprising multiple lumens.

A humidifier that can easily control temperature and humidity in an independent manner, irrespective of a flow rate of medical gas to be supplied, is provided. The humidifier is connected to a respiratory assistance device configured to regulate or assist ventilation of a user. The humidifier is configured to add moisture to gas fed from a gas source in the form of fine particles or water vapor. The humidifier includes a liquid container configured to contain liquid containing at least water, a mist-droplet generation unit configured to generate mist droplets being fine particles of the liquid, and a water retaining member configured to hold at least a part of the mist droplets.

A medical tube transports gases to and/or from a patient. The medical tube includes a bead wrapped around a longitudinal axis of the medical tube. The bead forms a first portion of a lumen wall of the medical tube. The medical tube also includes a film wrapped around the longitudinal axis of the medical tube. A first portion of the film overlies the bead, and a second portion of the film forms a second portion of the lumen wall. The lumen wall, formed by the bead and the second portion of the film forms a substantially smooth bore. The medical tube can be reusable or reprocessable.

An adjustable heat and moisture exchanger (HME) for use with a breathing apparatus to humidify air comprising: an inlet for coupling to a source of air, and an outlet for delivering air to a patient and an air flow path between them, HME material in the flow path with two or more surfaces exposed to the air flow path to exchange humidity between patient air flow and an inlet air flow, at least one adjuster for adjusting the configuration of the HME material and/or the air flow to alter the air flow over the surfaces of the HME material to alter the exchange of humidity.

A passive valve for use as a fixed leak valve. The valve includes a body having an internal chamber, first and second body ports in fluid communication with the chamber with the first port configured for fluid communication with a patient connection and the second body port configured for fluid communication with a ventilator, a body passageway in fluid communication with the chamber and with ambient air exterior of the body, and a check valve seal positioned to seal the body passageway to permit the flow of gas within the chamber through the body passageway to the exterior of the body and to prevent the flow of ambient air exterior of the body through the body passageway into the chamber. In alternative embodiments, the valve is incorporated into the patient connection or constructed as a separate part connectable to the patient connection.

A filter cartridge for surgical gas delivery systems includes a filter housing configured to be seated in a filter cartridge interface of a surgical gas delivery system. A first filter element is seated in a first end portion of the filter housing. A second filter element is seated in a second end portion of the filter housing opposite the first end portion. A third filter element is seated in the filter housing between the first and second filter elements. The third filter element can include an activated carbon material, such as an activated carbon disc.
