摘要： A respiratory treatment device having an inlet configured to receive exhaled air into the device, an outlet configured to permit exhaled air to exit the device, a valve moveable in response to a threshold exhalation pressure at the inlet between a closed position where the flow of air from the inlet to the outlet is restricted, and an open exhalation position where the flow of air from the inlet to the outlet is less restricted, and a valve brace configured to support the valve, wherein a position of the valve brace relative to the valve is selectively adjustable to increase or decrease the threshold exhalation pressure.

摘要： Condensation or “rain-out” is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube preferably incorporating a heater wire.

摘要： 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.

摘要： 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.

摘要： A selective-sorting system for aerosol droplets in human breath includes a mouthpiece to receive a flow of human breath, and a flow path coupled to the mouthpiece. This flow path includes one or more bends that cause the flow of human breath to change direction, which causes aerosol droplets in the flow having different mass-sizes to change direction at different rates. Moreover, the flow path is shaped so that droplets that change direction at different rates are directed to different destinations. The system also includes a collection path, which is coupled to the flow path so that aerosol droplets meeting a specific mass-size criterion are directed into the collection path. A condenser tube is located in the collection path, wherein the condenser tube includes a cooling mechanism that cools the condenser tube to facilitate condensing aerosol droplets to sides of the condenser tube for subsequent collection.

摘要： Systems and methods for providing respiratory therapy are disclosed. The system includes a nebulizer operable to aerosolize a medicament, a cylindrical mixing chamber, an impacting cap and a recirculation tube. The mixing chamber has an inlet port, an outlet port, an aerosol port in fluid communication with the nebulizer, and a drainage port. The inlet port receives a flow of breathing gas. The mixing chamber receives the aerosol via the aerosol port, entrains aerosol into the flow of breathing gas, and delivers the breathing gas entrained with aerosol to the outlet port. The impacting cap receives and coalesces a portion of the aerosol into droplets within the space defined by the mixing chamber and the impacting cap. The mixing chamber is also configured to direct rain-out resulting from the droplets to the drainage port. The system also includes a recirculation tube to return the rain-out to the nebulizer.

摘要： The nebulizer gas scavenging system includes a condenser positioned in the expiratory pathway of the breathing circuit for extracting liquid from expiratory gases and redirecting the extracting liquid to the input of the nebulizer. The system is further configured to detect the actual consumption of inhaled medication by measuring the concentration of medication in the expiratory pathway and comparing it to the initial content of medication in the aerosol of the inspiratory pathway. A more accurate determination of the amount of inhaled medication is advantageous in certain critical situations involving application of medication by inhalation.

摘要： Embodiments relate to systems and methods for therapeutic gas delivery for personal medical consumption. A hydrogen delivery system herein can include one or more electrolytic cores which use source water to carry out electrolysis-based reactions, and obtain free hydrogen (H2) gas which can be separated using a proton exchange membrane (PEM) or other filter for collection and delivery to a user. In aspects, the electrolytic core or cores can be constructed or scaled to produce a sufficient amount of hydrogen (H2) gas so that the user can ingest that gas directly, immediately, and/or in real-time or near real-time, without a need for storage of the gas. In aspects, the system can be portable, and configured with a vent port to eliminate oxygen (O2) gas that may accumulate during electrolytic reactions, and also a coalescer unit to reduce or eliminate water or water vapor from the output hydrogen (H2) gas.
