Title (EN) CLOSED CIRCUIT FORCED HOT AIR INTRAOPERATIVE PATIENT WARMER WITH IMPROVED STERILITY
(FR) DISPOSITIF DE RÉCHAUFFEMENT PEROPÉRATOIRE DES PATIENTS À AIR CHAUD PULSÉ EN CIRCUIT FERMÉ PRÉSENTANT UNE STÉRILITÉ AMÉLIORÉE
Abstract:
(EN) A system for a closed circuit forced hot air warmer of patient beds and blankets with improved sterility has a patient mattress or blanket microprocessor controlled warmer that circulates heated air in a closed system without releasing warmed air into the area surrounding the patient or into the operating room. The system helps to avoid the exposure of patients and hospital workers in the operating room to possible infecting microbes carried in unsterile turbulent air currents related to the release of air from non-closed systems. The machinery and flexible hoses of the system are initially sterilized by a microprocessor controlled antimicrobial mist generator, The system does not discharge jets of wanned air due to the closed circuit arrangement. Turbulent air flow previously produced in the vicinity of the patient by high velocity air jets is eliminated. An ambient, quiescent condition accorded by closed circuit heating prevents infection of patients and operating room personnel by microbe migration.
(FR) L'invention concerne un système pour dispositif de réchauffement à air chaud pulsé en circuit fermé des lits et couvertures des patients qui présente une stérilité améliorée, ledit système comprenant un dispositif de réchauffement du matelas ou de la couverture d'un patient commandé par microprocesseur et faisant circuler de l'air chauffé dans un système fermé sans dégager d'air chauffé dans la zone autour du patient ni dans le bloc opératoire. Le système aide à éviter que les patients et le personnel hospitalier se trouvant dans le bloc opératoire ne soient exposés à d'éventuels microbes infectieux transportés par les courants d'air turbulent non stériles liés au dégagement d'air par les systèmes non fermés. Les machines et tuyaux flexibles du système sont initialement stérilisés par un nébulisateur antimicrobien commandé par microprocesseur. Le système ne libère pas de jets d'air chauffé du fait de la configuration en circuit fermé. Le flux d'air turbulent qui était auparavant produit à proximité du patient par des jets d'air haute vitesse est éliminé. Un état de repos environnant permis par le chauffage en circuit fermé empêche que les patients et le personnel de bloc opératoire ne soient infectés par migration des microbes.
