Abstract: A method and apparatus can be used in the selection of correctly sized respiratory interfaces. The method includes the use of light beams to project sizing markers onto a patient's face, which enables the size of the patient's facial features to be measured relative to a set of interface sizes. A sizing apparatus can include a light source and beam splitters that will refract and project the light source into a series of beams that can be aligned on a patient's face in order to measure the features of the patient.

Abstract: Medical breathing tubes have a tubular body that defines a lumen extending between open terminal ends of the tubular body. An internal form is enclosed within the lumen and supportive of the tubular body. The internal form may be a coated encapsulated internal form where the coating secures the internal form to the tubular body. The internal form may provide for a series of alternative crests and troughs of the tubular body. A patient interface and/or a securement system may be attached to the tubular body.

Abstract: This invention relates to medical breathing tubes comprising a tubular body, the body defining a lumen extending between open terminal ends of the body and an internal form enclosed within the lumen and supportive of the tubular body. The internal form may be of a coated encapsulated internal form, the coating securing the internal form to the tubular body. The internal form may also or separately provide for a series of alternative crests and troughs (e.g. corrugations) of the tubular body. Patient interfaces (such as masks or nasal cannula) can be connected to such tubing. A system for securing patient interfaces in an operational position may also be utilised.
