摘要：
A portable automatic tourniquet (100) comprising a cuff (1). A gas intake valve (10) is provided on the outer surface (12) of the cuff (1). The gas intake valve (10) is connected to a gas pressure control apparatus (3) via a gas intake tube (4). A gas pressure sensor (13) is provided on the inner surface (11) of the cuff (1). A gas inlet (35) and a gas outlet (36) are provided on the gas pressure control apparatus (3). The gas pressure control apparatus (3) comprises a microcontroller (30) and a miniature gas pump (33). The gas pressure sensor (13) is used for detecting the gas pressure in the cuff (1). The microcontroller (30) is used for controlling, on the basis of the gas pressure in the cuff (1), the miniature gas pump (33) to draw a gas via the gas inlet (35) to inflate the cuff (1) or controlling the miniature gas pump (33) to discharge the gas in the cuff (1) via the gas outlet (36) to automatically regulate the pressure that the cuff (1) applies to a wound surface for bleeding control of the wound surface. The apparatus (100) effectively prevents ischemic necrosis of muscle tissues at the wound surface due to excessive bleeding control pressure being applied by the cuff (1) to the wound surface and poor bleeding control effects due to insufficient bleeding control pressure being applied to the wound surface.Linvention concerne un garrot automatique portable (100) comprenant un manchon (1). Une soupape dadmission de gaz (10) est disposée sur la surface externe (12) du manchon (1). La soupape dadmission de gaz (10) est raccordée à un appareil de commande de pression de gaz (3) par lintermédiaire dun tube dadmission 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 lappareil de commande de pression de gaz (3). Lappareil de commande de pression de gaz (3) comprend un microcontrôleur (30) et une pompe à gaz miniature (33). Le capteur de pression
