Abstract
Methods of manufacturing components and devices for providing respiratory pressure therapy, and components manufactured according to the methods. Support structures are provided for the components. In embodiments, the support structures may be rigid rings. Alternatively, resilient materials are applied to components to create resilient reinforcing elements. The devices and components include conduits to deliver flows of pressurised gas to a patient interface, positioning and stabilising structures having headgear tubes with support elements, and patient interfaces including the conduits.
Claims22
An air delivery conduit configured to convey a flow of air under pressure from a respiratory pressure therapy device to a patient interface for providing respiratory pressure therapy to a patient, the air delivery conduit comprising:
- a flexible reinforcing structure provided along a length of the air delivery conduit;
- and
- an air impermeable covering provided to the flexible reinforcing structure along the length of the air delivery conduit, the air impermeable covering forming a sealed air path through which the flow of air is able to be conveyed in use, the air impermeable covering comprising:
- a sealing layer provided to the flexible reinforcing structure;
- and
- a sheet wrapped around the flexible reinforcing structure, the sheet comprising a first edge and a second edge each extending along the air delivery conduit and meeting or overlapping to form a seam, an outer side, and an inner side, the inner side of the sheet comprising:
- a first portion on a first side proximate the first edge;
- and
- a second portion proximate the first edge, on a second side opposite the first side
- wherein the scaling layer extends across an inner side of the seam to seal between the first portion of the inner side of the sheet and the second portion of the inner side of the sheet.
An air delivery conduit configured to convey a flow of air under pressure from a respiratory pressure therapy device to a patient interface for providing respiratory pressure therapy to a patient, the air delivery conduit comprising:
- a flexible reinforcing structure provided along a length of the air delivery conduit;
- a scaling strip applied to the flexible reinforcing structure;
- and
- an air impermeable covering wrapped around the flexible reinforcing structure and the sealing strip, the air impermeable covering forming a sealed air path through which the flow of air is able to be conveyed in use, the air impermeable covering having a first edge and a second edge each extending along the air delivery conduit, the first edge and the second edge meeting or overlapping to form a seam,
- wherein the sealing strip extends across an inner portion of the seam to prevent air leaking through the seam, the sealing strip being in contact with an inner side of the air impermeable covering on both sides of the seam.
An air delivery conduit configured to convey a flow of air under pressure from a respiratory pressure therapy device to a patient interface for providing respiratory pressure therapy to a patient, the air delivery conduit comprising:
- a flexible reinforcing structure provided along a length of the air delivery conduit;
- and
- an air impermeable covering provided to the flexible reinforcing structure along the length of the air delivery conduit, the air impermeable covering forming a sealed air path through which the flow of air is able to be conveyed in use, the air impermeable covering comprising a textile layer and a sealing layer laminated to the textile layer, the air impermeable covering being wrapped around the flexible reinforcing structure and comprising a first edge and a second edge each extending along the air delivery conduit and meeting or overlapping to form a seam, an outer side, and an inner side, the inner side of the air impermeable covering comprising:
- a first portion on a first side of the seam proximate the first edge;
- and
- a second portion proximate the first edge, on a second side of the seam opposite the first side,
- wherein a portion of the sealing layer extends beyond an edge of the textile layer at the first edge of the air impermeable covering to form a sealing flap, the sealing flap being sealed to another portion of an inner side of the sealing layer to extend across an inner side of the seam to seal between the first portion of the inner side of the air impermeable covering and the second portion of the inner side of the air impermeable covering.
