  • Publication number: 20220082192
    Abstract: A flexible hose has a length of hollow tubing and a closed cuff. A method for manufacturing a flexible hose, has the steps of providing a length of flexible tubing, providing a closable cuff, aligning the closable cuff with the hollow tubing at a closed cuff location, and affixing the closable cuff to the length of hollow tubing by closing the closable cuff around the length of hollow tubing at the closed cuff location, thereby forming a flexible hose having a closed cuff. The method does not include the step of screwing the closable cuff onto the length of hollow tubing. Devices may also contain such a flexible hose.

  • Publication number: 20170143931
    Abstract: A micro-humidifier for operably-connecting to a breathing circuit contains a liquid feed, a liquid chamber operably-connected to the liquid feed, and a vapour generator operably-connected to the liquid chamber. The liquid chamber has a volume of from about 0.01 mL to about 30 mL. The micro-humidifier is operably-connected to and/or is designed to be operably-connected to a breathing circuit upstream of the patient. When the micro-humidifier is operably-connected to a breathing circuit, the vapour from the vapour generator enters into the breathing circuit. A respiratory humidification system contains the a breathing circuit and the micro-humidifier as described herein. The micro-humidifier is operably-connected to the breathing circuit upstream of the patient, and the vapour from the vapour generator enters into the breathing circuit.
