Heating elements for respiratory tubing (73) comprise an electrically-insulating substrate (22, 45, 50) with a printed looped track (21, 31, 41) of carbon extending along the substrate between two metal terminals (25, 26, 43, 44, 74, 75) at one end. The heating elements are preferably made by printing several looped tracks (51 to 59) side by side on an insulative substrate (50), applying a metal bus bar (60) along one edge (61) of the sheet over the free ends of the track loops. The bus bar is cut between the free ends of the tracks (51 and 59) to form isolated terminal pads connected with opposite ends of the tracks. The sheet is cut (63) between the tracks (51 to 59) to divide it into separate heating elements.
摘要:
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.
摘要:
A respiratory assistance apparatus (4) is provided, adapted to deliver gases to a user or patient (1). The apparatus (4) comprises a housing (10) provided with a chamber (5) and a heater (25), the chamber (5) comprising at least one gas port (15) connected to, or arranged to be connected to, at least one intermediate passageway (12). The apparatus (4) is operative according to a disinfection mode of predetermined profile in which the heater (25) heats liquid in the chamber (5) to produce vapour at or above a target dewpoint temperature and/or humidity level. The apparatus (4) is arranged such that the vapour is delivered to the intermediate passageway (12) to disinfect the intermediate passageway (12) with moist heat throughout a predetermined duration of the disinfection mode. Associated attachments and methods are also provided.
摘要:
A breathing assistance apparatus is designed for use with delivery of respiratory gases to a patient. The breathing assistance apparatus includes a patient interface, having a body section adapted to cover the nose, or nose and mouth of a patient and a sealing interface. The sealing interface includes at least an outer sealing member. The outer sealing member is adapted to attach to the body section in a sealing manner and has a substantially thin section in at least its nasal bridge region. The thin section is substantially thinner than the rest of the outer sealing member.
摘要:
A nasal cannula assembly (20) is disclosed having a face mount part (21), in use resting against a user's face, which includes at least one nasal prong (22) capable of being fitted into a person's nares. The cannula assembly (20) also includes a manifold part (24), in fluid communication with the face mount part (21), having a single horizontal side gases entry. In particular, this cannula assembly (20) is for supplying heated, humidified gases to a patient suffering from COPD. A tie or lanyard (73) is disclosed for use with a breathing assistance apparatus such as a nasal cannula (20), face or nasal mask or tracheostomy connector (69). The tie or lanyard (73) transfers the weight of the conduits supplying gases (95) to the breathing assistance apparatus from the breathing assistance apparatus and distributes it onto the neck of the patient.
摘要:
A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.
摘要:
In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.
