Abstract
The present invention relates to systems and methods for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising: a mechanical coupler comprising means for restricting the jaw position of the patient; means for recording an utterance; and processing means for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value. In addition the present invention relates to the use of the above mentioned systems as a diagnostics tool for assessing obstructive sleep apnea.
Claims15
A system (10) for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising:
- a mechanical coupler (1) comprising means for restricting the jaw position of the patient;
- means (2) for recording an utterance:
- and
- processing means (5) for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value.
A method for assessing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising the steps of:
- restricting a jaw position of the patient;
- recording an utterance;
- comparing the recorded utterance with a threshold value;
- and
- determining said at least one anatomical parameter of the upper airway from the recorded utterance and the comparison of the recorded utterance with a threshold value.
