In the preferred embodiment, the wound bleeding monitoring system 10 includes, but is not limited to, a wound pressure monitoring module 101, a wound bleeding monitoring module 102, a vital sign monitoring module 103, and a wound bleeding alarm module 104.

In the present embodiment, since the first sensor 21 is disposed at a position around the wound, the first pressure value at the position around the wound is always maintained. Since the second sensor 22 is placed at the wound bleeding location, the second pressure value at the wound bleeding location increases as the wound bleeds. Therefore, when the pressure sensed by the second pressure sensor 22 is significantly increased, that is, the pressure difference between the first pressure value and the second pressure value becomes large, indicating that the wound is bleeding.
所述伤口出血监测模块102用于通过智能纱布2的蓝牙端口24从智能纱布2中的颜色传感器23获取智能纱布2的颜色值，以及根据所述智能纱布2的颜色值判断智能纱布2是否浸满血。在本实施例中，所述智能纱布2未浸满血时，颜色为白色，若所述智能纱布2浸满血时，颜色为红色。所述智能纱布2浸满血时，吸收的血量为500ml左右。The wound bleeding monitoring module 102 is configured to acquire the color value of the smart gauze 2 from the color sensor 23 in the smart gauze 2 through the Bluetooth port 24 of the smart gauze 2, and determine whether the smart gauze 2 is digested according to the color value of the smart gauze 2 Full of blood.
