Abstract
A respiratory mask can include one or a plurality of force sensors configured to detect a force imparted to a user's skin. Output from the one or more sensors can be represented in a way useful to the patient or healthcare provider for adjusting the mask to achieve a desired fitment. A representation of the detected forces can be displayed on a separate display device or on the mask.
Claims21
(canceled)
A respiratory mask comprising:
- a seal portion comprising a sealing surface configured to form a seal with a patient's face;
- a plurality of elastic sensors are configured to detect a force applied to the seal portion;
- and
- wherein the plurality of elastic sensors comprise layered capacitive sensors, and
- wherein the plurality of elastic sensors comprise a first longitudinal layer including a first electrode and second and third transverse layers including second and third electrodes overlapping the first electrode, wherein the first and second electrodes from a first capacitive sensor and the first and third electrodes form a second capacitive sensor.
2 more elements
A respiratory mask comprising
- a seal portion comprising a sealing surface configured to form a seal with a patient's face;
- at least one elastic sensor configured to detect a force applied to the seal portion;
- and
- wherein the at least one elastic sensor is a layered capacitive sensor comprising a plurality of layers of electrodes with a dielectric layer disposed between each of the plurality of layers of electrodes, such that the elastic sensor comprises a plurality of capacitors in a configuration in which they share at least one electrode.
