Abstract

L'invention concerne un garrot automatique portable (100) comprenant un manchon (1). Une soupape d'admission de gaz (10) est disposée sur la surface externe (12) du manchon (1). La soupape d'admission de gaz (10) est raccordée à un appareil de commande de pression de gaz (3) par l'intermédiaire d'un tube d'admission de gaz (4). Un capteur de pression de gaz (13) est disposé sur la surface interne (11) du manchon (1). Une entrée de gaz (35) et une sortie de gaz (36) sont prévues sur l'appareil de commande de pression de gaz (3). L'appareil de commande de pression de gaz (3) comprend un microcontrôleur (30) et une pompe à gaz miniature (33). Le capteur de pression de gaz (13) est utilisé pour détecter la pression de gaz dans le manchon (1). Le microcontrôleur (30) est utilisé pour commander, sur la base de la pression de gaz dans le manchon (1), l'aspiration par la pompe à gaz miniature (33) d'un gaz par l'intermédiaire de l'entrée de gaz (35) afin de gonfler le manchon (1) ou commander la décharge par la pompe à gaz miniature (33) du gaz dans le manchon (1) par l'intermédiaire de la sortie de gaz (36) afin de réguler automatiquement la pression que le manchon (1) applique sur une surface de plaie pour le contrôle du saignement de la surface de plaie. L'appareil (100) prévient efficacement la nécrose ischémique de tissus musculaires à la surface de la plaie due à une pression de contrôle du saignement excessive appliquée par le manchon (1) à la surface de la plaie et les mauvais effets du contrôle du saignement dus à une pression de contrôle du saignement insuffisante appliquée à la surface de la plaie.
