Abstract: A flow diverter valve is used in controlling the pressure and/or flow rate of a breathable gas supplied to the airways of a patient by a breathable gas flow generator supply apparatus during, for example, ventilatory assistance treatments such as non-invasive positive pressure ventilation and nasal Continuous Positive Airway Pressure (CPAP) treatment of Obstructive Sleep Apnea. The flow diverter valve includes a vane and a housing. The housing has an inlet port, an outlet port, and an exhaust port. The exhaust port opens to atmosphere, and the inlet port is in fluid communication with the flow generator. The outlet port is in fluid communication with a patient mask via a conduit. The vane is configured with respect to the housing such that a blower associated with the CPAP apparatus remains substantially unchoked, regardless of whether the vane is in the open or closed position.

Abstract: The invention relates to a device for separating gas and liquid streams, especially in tracheal catheters of patients, comprising a housing having channels for the delivery and removal of sputum. The aim of the invention is to ensure unrestricted delivery and removal of respiratory air and reliable removal of sputum. To this end, the invention provides for the arrangement of an at least spherical segment-shaped closed housing (1) comprising tubular channels (4, 5) which are located a distance apart in the area of the end surface (2) of the housing (1), each leading to a connection to the tracheal catheter and guiding through respiratory air; and a tubular channel (6) for removing sputum to the exterior, the inner front end of this channel being sealed and a suction tube (7) consisting of highly flexible or resilient elastic material lying adjacent to the inside of the channel. Said suction tube can be bent or turned autonomously by the force of gravity, extends crosswise to the sputum channel (6) and from a distance can reach approximately as far as the inner wall of the housing (1) with its free end.

Abstract: There is described a demand valve for a breathing apparatus with a nullfirst breathnull mechanism, wherein a demand valve is held closed by resiliently latching an operating diaphragm of the valve in a position wherein the valve is closed. The diaphragm is resiliently biased towards opening the valve, and the resilient latch is arranged to exert sufficient force so as not to be overcome by the resilient bias alone, but so as to be overcome by the combination of the resilient bias and a predetermined pressure difference across the diaphragm caused by sub-ambient pressure within the facepiece of the breathing apparatus.

Abstract: A hand-held breathing device for use by patients having respiratory problems creates a sealed backpressure in the airways of the patient by creating resistance to exhalation. A peep valve is mounted inside a hollow body, and a pre-set compression spring is mounted between the valve and an adjustable cap or cam lever in the main body of the device. A pair of valve openings extend through the wall of the main body, one opening serving as an intake port for inhaling of air by the patient and the second portnullfor exhalation of carbon dioxide. An intake valve is mounted inside the body between a normally open end of the device and the exhalation valve. In one of the embodiments, the device is attached to a nebulizer to facilitate buildup of positive pressure and delivery of medication to the patients' lungs.
