The module referred to in the embodiment of the present invention is a series of computer program instruction segments that can be executed by the microprocessor 17 of the intelligent monitoring terminal 1 and can perform a fixed function, and is stored in the memory 16 of the intelligent monitoring terminal 1.
Wound pressure monitoring module 101 is used for obtaining first pressure value from intelligent gauze 2's first pressure sensor 21 through intelligent gauze 2's bluetooth port 24, obtains the second pressure value from intelligent gauze 2's second pressure sensor 22, calculates the pressure differential of first pressure value and second pressure value, and judges whether the pressure differential changes and monitors the wound and whether bleeding. In the present embodiment, since the first sensor 21 is disposed at the peripheral position of the wound, the first pressure value at the peripheral position of the wound is always kept constant. Since the second sensor 22 is disposed at the wound hemorrhage site, the second pressure value at the wound hemorrhage site may increase when the wound bleeds. Thus, when the pressure sensed by the second pressure sensor 22 becomes significantly greater, i.e., the pressure difference between the first pressure value and the second pressure value becomes greater, it is indicated that the wound is bleeding.

In general, the pulse value of a normal adult is 60-100 times/min. The blood pressure standard of normal people is systolic pressure of 90-140mmHg and diastolic pressure of 60-90 mmHg.
The wound bleeding alarm module 104 is used for generating a first alarm message for prompting the wounded to lose blood slightly (the bleeding amount is less than 500ml) when the pulse value and the blood pressure value of the wounded are both normal, generating a second alarm message for prompting the wounded to lose blood moderately (the bleeding amount is 500-1000ml) when the pulse value of the wounded is in a first pulse range (for example, 100-times per minute) and the systolic pressure of the wounded is in a first systolic pressure range (for example, 80-90mmHg), generating a third alarm message for prompting the wounded to lose blood severely (the bleeding amount is more than 1000ml) when the pulse value of the wounded is more than a second pulse range (for example, 120-times per minute) and the systolic pressure of the wounded is less than a second systolic pressure range (for example, 70-80mmHg), and generating a first alarm message for prompting the wounded to lose blood urgently (the bleeding amount is more than 1600ml) when the pulse value of the wounded is zero and the systolic pressure of the wounded is in a third systolic pressure range (for example, 50-70mmHg) And fourthly, alarming information.
The wound bleeding alarm module 104 is further configured to display the first, second, third, or fourth alarm information on the display unit 14, or send the first, second, third, or fourth alarm information to a medical emergency platform of the rear emergency command center through the communication unit 15, so as to monitor the bleeding condition vital signs of the injured person, thereby facilitating the rear emergency command center to immediately grasp the injured condition of the injured person to formulate an optimal emergency plan.
In this embodiment, when the pressure difference does not change significantly and the color sensor 23 does not sense that the intelligent gauze 2 is full of blood, but the pulse value and the blood pressure value of the wounded are both significantly abnormal, at this time, the wound bleeding alarm module 104 is further configured to generate fifth alarm information for prompting the wounded to have internal bleeding, and display the fifth alarm information on the display unit 14 or send the fifth alarm information to a medical emergency platform of a rear emergency command center through the communication unit 15.

Step S304, judging whether the pressure difference changes or not; specifically, the wound pressure monitoring module 101 determines whether the pressure difference changes to monitor whether bleeding occurs in the wound of the wounded. If the pressure difference is not changed, the process returns to step S302; if the pressure difference changes, the process proceeds to step S305. In this embodiment, when the pressure sensed by the second pressure sensor 22 becomes significantly greater, i.e. the pressure difference between the first pressure value and the second pressure value becomes greater, it indicates that the wound is bleeding.
Step S305, acquiring a color value of the intelligent gauze from a color sensor in the intelligent gauze through a Bluetooth port in the intelligent gauze; in the present embodiment, the wound bleeding monitoring module 102 acquires 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.
Step S306, judging whether the intelligent gauze is full of blood or not; in this embodiment, the wound bleeding monitoring module 102 determines whether the intelligent gauze 2 is full of blood according to the color value of the intelligent gauze 2. When the intelligent gauze 2 is not full of blood, returning to the step S305; when the smart gauze 2 is saturated with blood, step S307 is performed. When the intelligent gauze 2 is not full of blood, the color is white, and when the intelligent gauze 2 is full of blood, the color is red.

Step S308, judging whether the pulse value and the blood pressure value are normal or not; in this embodiment, the vital sign monitoring module 103 determines whether the pulse value and the blood pressure value of the injured person are normal. In general, the pulse value of a normal adult is 60-100 times/min. The blood pressure standard of normal people is systolic pressure of 90-140mmHg and diastolic pressure of 60-90 mmHg.
Step S309, generating a first alarm message for prompting the wounded to slightly lose blood; specifically, when the pulse value and the blood pressure value of the wounded are both normal, the wound bleeding alarm module 104 generates a first alarm message indicating that the wounded have slight blood loss (the bleeding amount is less than 500 ml).
In step S310, when the pulse value of the injured person is within the first pulse range (e.g. 100-.
In step S311, when the pulse value of the wounded is greater than the second pulse range (e.g. 120 times/min) and the systolic pressure of the wounded is less than the second systolic pressure range (e.g. 70-80mmHg), the wound bleeding alarm module 104 generates a third alarm message indicating that the wounded has severe blood loss (bleeding amount is greater than 1000 ml).
In step S312, when the pulse value of the wounded is zero and the systolic pressure of the wounded is within the third systolic pressure range (e.g., 50-70mmHg), the wound bleeding alarm module 104 generates a fourth alarm message to prompt the wounded to threaten blood loss (the bleeding amount is greater than 1600 ml).
Step S313, the wound bleeding alarm module 104 displays the first, second, third or fourth alarm information on the display unit 14, or sends the first, second, third or fourth alarm information to a medical emergency platform of the rear emergency command center through the communication unit 15, so as to monitor the bleeding vital signs of the wounded, thereby facilitating the rear emergency command center to immediately grasp the wounded situation to formulate an optimal emergency plan.
In this embodiment, when the first pressure sensor 21 and the second pressure sensor 22 do not sense that the pressure difference changes significantly and the color sensor 23 does not sense that the intelligent gauze 2 is full of blood, but the pulse value and the blood pressure value of the wounded are both significantly abnormal, the wound bleeding alarm module 104 generates a fifth alarm message prompting the wounded to have internal bleeding, and displays the fifth alarm message on the display unit 14 or sends the fifth alarm message to a medical emergency platform of a rear emergency command center through the communication unit 15.
