Abstract

La présente invention concerne un ventilateur médical ayant la capacité de purifier l'air. Le ventilateur médical de dispositif est largement utilisé dans le traitement médical et d'urgence de patients. La présente invention utilise un moteur sans balai et une lumière UVC. A l'aide du mécanisme de vis-mère linéaire, le moteur sans balai entraîne le mouvement de va-et-vient du bras relié au mécanisme de vis-mère linéaire. Chaque fois que le bras appuie sur deux ballons Ambu, il les comprime et l'air sortant des ballons Ambu fournit les besoins respiratoires de deux patients. Le microcontrôleur et la partie électronique du dispositif régulent de manière intelligente le nombre de respirations par minute et la quantité et le volume de pression de l'air sortant des ballons Ambu. La lumière UVC du dispositif nettoie l'air à l'intérieur des ballons Ambu des bactéries et des virus pour empêcher l'aggravation d'une infection interne chez des patients atteints de lésions pulmonaires.
