Closure of a fluid trap for a respiratory therapy device

In one embodiment, a breathing circuit component is provided and includes: an inlet; an outlet; and an enclosing wall defining a gases passageway between the inlet and the outlet, at least a region of the wall comprising a membrane that allows the passage of water vapour without substantially allowing the passage of liquid water or respiratory gases, wherein, the membrane has a thickness of about 35 to 45 micrometers.

Container of a fluid trap for a respiratory device

Fluid trap for a respiratory device

Disclosed is a fluid trap for use with, or comprising part of, a respiratory therapy system, d particular comprising part of, or configured to be connected to, a breathing limb, such as an expiratory limb, of a respiratory therapy system. The fluid trap comprises a container configured to contain fluid received from an inlet; a closure, the closure and container being configured to be removeably mounted together to close the container; and a valve configured to be removeably mounted on at least one of the container and the closure, and configured to be in a closed condition which prevents fluid from flowing through the inlet when the closure is not mounted on the container, the valve being further configured to be in an open position which allows fluid from the inlet into the container when the closure is mounted on the container.

Fluid trap for a respiratory therapy system

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

Limb for breathing circuit

A medical tube has a tube wall defining a passageway for transportation of gases and further has a first end and a second end. At least one end of the medical tube comprises one or more of a pre-formed pneumatic port component, a pre-formed electrical port component, and a pre-formed sensor port component. A cuff is over-moulded about and thereby connects the pneumatic port component, the electrical port component, and/or the sensor port component and at least a portion of the tube end.

Component for medical circuit

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

Conduit and method of forming

A medical tube has a tube wall defining a passageway for transportation of gases and further has a first end and a second end. At least one end of the medical tube comprises one or more of a pre-formed pneumatic port component, a pre-formed electrical port component, and a pre-formed sensor port component. A cuff is over-molded about and thereby connects the pneumatic port component, the electrical port component, and/or the sensor port component and at least a portion of the tube end.
