Patent Images
1. An interface sizing tool, comprising:
- a body;
a light source supported relative to the body, the light source configured to project a primary beam of light; and
one or more light manipulation arrangements configured to manipulate the primary beam of light to project a reference light beam and one or more sizing light beams onto the face of a patient;
wherein each of the reference light beam and the one or more sizing light beams is configured to be projected in a direction parallel to the others;
wherein the reference light beam is configured to generate a reference marker on the face of the patient, and each of one or more sizing light beams is configured to generate a sizing marker on the face of the patient; and
wherein a location of each sizing marker indicates an interface size.

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.

19. A method of sizing a patient for an interface, comprising:
-
projecting a reference light beam and one or more sizing light beams onto the face of a patient in a direction parallel to the others, wherein the reference light beam is configured to generate a reference marker on the face of the patient, and each of one or more sizing light beams is configured to generate a sizing marker on the face of the patient; and determining the size of an interface to be used on the patient based on the location of the reference marker and the one or more sizing markers. - View Dependent Claims (20, 21)
