摘要：
A pneumatic automatic hemostasis apparatus and method, the method comprising the steps of: starting a timer to calculate hemostasis time of a tourniquet acting on a wound surface (S42) controlling a miniature air pump to draw in air by means of air inlet holes to inflate the tourniquet (S43) and acquiring an air pressure value in the tourniquet from an air pressure sensor (S44) when the air pressure value is less than a first preset value, continuing controlling the miniature air pump to draw in the air by means of the air inlet holes to inflate the tourniquet when the air pressure value is greater than a second preset value, controlling the miniature air pump to deflate the tourniquet by means of air outlet holes when the air pressure value is between the first preset value and the second preset value (S45), determining whether the hemostasis time reaches a preset time (S47) and when the hemostasis time reaches the preset time, controlling a loudspeaker to playback voice message to inform medical personnel to check the hemostasis conditions of the wound surface (S48). The method may effectively prevent the problem of poor hemostatic effects caused by hemostasis pressure of the tourniquet acting on the wound surface being too high or too low, and the problem of wound tissue necrosis caused by continuous vascular compression over a long period of time.Linvention concerne un appareil et un procédé dhémostase automatique pneumatique, le procédé comprenant les étapes consistant à : démarrer un temporisateur pour calculer le temps dhémostase dun garrot agissant sur une surface de plaie (S42) commander une pompe à air miniature pour quelle aspire de lair au moyen de trous dentrée dair pour gonfler le garrot (S43) et acquérir une valeur de pression dair dans le garrot à partir dun capteur de pression dair (S44) lorsque la valeur de pression dair est inférieure à une première valeur prédéfinie, poursuivre la commande de la pompe à air miniature pour quelle aspire lair au mo
