APPARATUS FOR SLEEP POSTURE CORRECTION

摘要

A sleep posture alerting apparatus is arranged to detect a sleep posture of a person and the person is automatically alerted by an alarming device when the sleep posture is out of a predetermined body posture range. However, the alerting of the person is provided only in a part of the occasions, when his/her body posture is out of the predefined body posture range. Alerting only in part of the occasions positively contributes to a learning curve which makes the use of the apparatus more effective. This is advantageous for a user who has just started with a positional therapy. The sleep of the user is not disturbed every time when the user turns to a supine position which allows the user to get trained in positional therapy under soft conditions. The feature makes the positional therapy less strict. Further, it is advantageous to alert only in occasions during a lighter sleep stage which does advantageously less disturb a naturel sleep rest than alerting during a deeper sleep stage.
