Abstract

L'invention concerne un système support à matelas d'air, en tant que surface servant de couchette pour patients, en particulier pour tables d'opération ou lits pour malades, également dans le cas de soins infirmiers ou de soins pour personnes âgés, utilisé principalement pour assurer une protection contre un refroidissement excessif, par accumulation de la chaleur propre, ainsi que pour la prophylaxie et la thérapie du décubitus. Compte tenu des inconvénients de l'état connu de la technique, l'invention a pour but de fournir un système support répondant en grande partie aux exigences médicales, et qui soit, en outre, d'une construction simple et économique et soit approprié pour un usage unique. L'invention concerne, en conséquence, un système support à matelas d'air, comprenant au moins une première couche, ou feuille, souple (1) comportant une pluralité de coussins statiques (2), remplis de fluide, situés à distance entre eux, recouvert d'au moins une autre feuille (4) formant la surface d'utilisation pour le patient, ladite feuille étant reliée avec la première feuille (1) et/ou avec les coussins (2). Par suite des espaces libres entre les coussins individuels (2) de la première feuille (1) et la feuille de recouvrement (4), il se forme un espace creux (5) s'étendant sur toute la surface d'utilisation, espace servant de préférence d'espace collecteur de liquides résultant d'opérations, ou de zone d'équilibrage de température, ou encore de zone de massage. Les coussins statiques, de préférence remplis d'air, peuvent être adaptés à toutes les exigences et sont configurés de telle façon que la surface du corps du patient ne repose qu'en des emplacements en forme de points. Le positionnement du patient sur des emplacements en forme de points assure une irrigation améliorée des tissus et contribue de façon décisive, au moins pour une immobilisation prolongée, à la prophylaxie du décubitus.
