摘要： 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.

摘要： The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air. The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

摘要： The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

摘要： A system for cooling the brain of a human subject, the system including a cooling subsystem configured to input a flow of air or breathable gas, cool the air or breathable gas, and output cooled air or breathable gas to a line coupled to a device adapted to deliver the cooled air or breathable gas to a human subject. A flow control device coupled to the cooling subsystem is configured to control a flow rate of the flow of the air or breathable gas input to the cooling subsystem and a flow rate of the cooled air or breathable gas output to the line. One or more flow rate sensors coupled to the cooling subsystem are configured to measure at least a flow rate of flow of cooled air or breathable gas. One or more temperature sensors are configured to measure at least a temperature of a brain or a brain correlative site of the human subject and the temperature of the flow of cooled air or breathable gas. A controller is coupled to the cooling subsystem, the flow control device, the one or more flow rate sensors, and the one or more temperature sensors and is configured to adjust a cooling rate, the temperature, and the flow rate of flow of cooled air or breathable gas delivered to the human subject based on at least the measured temperature of the brain or the brain correlative site and the measured flow rate of the flow of cooled air or breathable gas to cool the brain of the human subject.

摘要： A pump arrangement for powering a pump in providing a controlled volume of water to a drip nozzle in a drip-feed humidifier. The pump arrangement includes: a pump having a solenoid; a processing unit; and a power supply electrically connected to the solenoid via a switch which is controlled by the processing unit. The power supply is structured to supply power to the solenoid via the switch. The processing unit is programmed to modulate the power provided to the solenoid via the switch such that the power is supplied to the solenoid according to a power profile for each actuation of the solenoid. The power profile includes: an initial portion which increases at a first overall rate, an intermediate portion which increases at a second overall rate different than the first overall rate, and a final portion which decreases at a third overall rate.

摘要： New medical circuit components and methods for forming such components are disclosed. These components include microstructures for humidification and/or condensate management. The disclosed microstructures can be incorporated into a variety of components, including tubes (e.g., inspiratory breathing tubes and expiratory breathing tubes and other tubing between various elements of a breathing circuit, such as ventilators, humidifiers, filters, water traps, sample lines, connectors, gas analyzers, and the like), Y-connectors, catheter mounts, humidifiers, and patient interfaces (e.g., masks for covering the nose and face, nasal masks, cannulas, nasal pillows, etc.), floats, probes, and sensors in a variety of medical circuits.

摘要： A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

摘要： A heat and moisture exchanger includes: a heat and moisture exchanger material formed by coiling a strip-shaped porous body, the porous body having a plurality of slits formed therein that are arranged along the lengthwise direction, into a spirally-wound shape with the slits facing radially outwardly; and a housing that accommodates the heat and moisture exchanger material. Such a structure for an HME makes it possible to reduce pressure loss and improve moisture retention capabilities by means of a relatively simple structure, thereby allowing the inexpensive provision of an HME that lowers the burden on a patient.
