According to a preferred embodiment, there is provided an electronic patient monitor for use in reducing the risk of decubitus ulcers. The monitor utilizes a separate sensor which senses the position of the patient in the bed or chair for purposes of determining when the patient moves. Additionally, the monitor broadcasts masking noise through its own, or through a remote, speaker, thereby enabling the patient to rest more comfortably in a noisy institutional environment. If the patient does not move on his or her own accord within a predetermined turn interval, the masking sound broadcast will be terminated which will gently encourage the patient to move. An alarm may additionally be sounded to notify the caregiver that the patient needs to be manually turned to reduce the risk of decubitus ulcers.

Un mode de réalisation préféré de l'invention concerne un dispositif électronique de surveillance de patient utilisé pour limiter les risques d'ulcères de décubitus. Le dispositif de surveillance se sert d'un capteur séparé qui détecte la position du patient dans le lit ou le fauteuil afin de déterminer les mouvements du patient. De plus, le dispositif de surveillance diffuse un bruit de masquage, de lui-même ou par l'intermédiaire d'un haut-parleur à distance, ce qui permet au patient de se reposer plus confortablement dans un environnement institutionnel bruyant. Si le patient n'effectue pas de mouvement de sa propre volonté pendant un intervalle de temps de retournement prédéterminé, la diffusion de bruit de masquage s'arrête, ce qui encourage doucement le patient à bouger. De plus, un avertissement sonore peut être émis pour informer la personne soignante que le patient a besoin d'être retourner manuellement pour limiter les risques d'ulcères de décubitus.
