[0026] As shown, Figure 6 And Figure 10As shown, the airbag attachment section 4 includes a manual control valve 4-1, a manual control valve housing 4-11, a large air vent 4-12, a diaphragm check valve 4-13, a baffle wall 4-14, and an inlet / outlet air pipe 4-6.

[0027] To use, install the manually inflatable, automatically deflated, alarm-type hemostatic ligature and charge it; the device is then ready for use.

[0028] When this utility model is used, its specific operation is as follows:

[0029] When using, such as Figure 11 As shown, place the air strap body 1 on the arm, then wrap the air strap body 1 around it and secure it with Velcro 6 and Velcro 7. At this point, the air strap body 1 is wrapped around the arm and adhered to the skin by the sanitary film 8. Then, the worker can pick up the control airbag 5 and turn the manual control valve 4-1 through the handle or control panel to rotate the valve control column 4-16 to the desired position. Figure 8As shown, the operator can then continuously squeeze the control airbag 5 to inflate the airbag body 1-2 in the air zipper 1. During inflation, as the control airbag 5 is squeezed from the side and axially elongated, the moving trigger block 5-3, which was originally in contact with the fixed trigger block 5-2, disengages from the fixed trigger block 5-2, thus breaking the electrical signal circuit. The control board 2-7 in the functional section 2 can then begin to operate. Simultaneously, when the control airbag 5 is squeezed, internal air enters the valve control column 4-16 of the manual control air valve 4-1 through the inlet / outlet air pipe 4-6 and the diaphragm check valve 4-13, and then exits through the large air hole 4-12 and the air pipe 3, exiting from the functional section air pipe of the functional section 2. Interface 2-4 leads to T-9. Since the electronic control valve 2-10 is closed at this time, airflow can only enter the airbag body 1-2 through the functional unit pressure measuring T-8 and the corresponding pipeline. Then, when the control airbag 5 recovers, external air enters the inlet / outlet pipe 4-6 through the external opening of the airbag auxiliary section 4, along the pipeline and the air inlet 4-5. As the control airbag 5 continues to move, the air then enters the airbag body 1-2 through the diaphragm check valve 4-13, the large air hole 4-12, the airbag auxiliary section air pipe interface 4-2, the air pipe 3, the functional unit air pipe interface 2-4, the T-9, and the functional unit pressure measuring T-8. As the air pressure inside the airbag body 1-2 gradually increases, the pressure gauge 2-3 begins to display the corresponding value. The staff can determine the pressure status based on the value, thereby ensuring smooth blood collection. As the control airbag 5 is continuously compressed and self-recovers, its internal fixed trigger block 5-2 and moving trigger block 5-3 are constantly contacting and separating. When the air pressure reaches the required value, the operator stops compressing the control airbag 5. The control board 2-7 will determine that the control airbag 5 is not moving after three seconds when the fixed trigger block 5-2 and moving trigger block 5-3 re-establish the current circuit. At this time, the control board 2-7 starts timing. After forty seconds, if the operator reverses the manual control valve 4-1 via the handle or control panel within forty seconds, causing the valve control column 4-16 to rotate to the desired position... Figure 10 In the indicated state, air in the airbag body 1-2 can be expelled from the device through the pressure testing three-way valves 2-8 and 2-9 and the electrically controlled valve 2-10, thereby relieving pressure on the limb's blood vessels. At this point, simply remove the air strap body 1. Due to the rapid decrease in pressure gauge 2-3, control board 2-7 determines that the device is in a safe state, stops the timer, and resets to await the next use. If no operation is performed within forty seconds, control board 2-7 controls buzzer 2-5 to sound an alarm. Twenty seconds after the alarm sounds, control board 2-7 controls electrically controlled valve 2-10 to open for twelve seconds, allowing air in the airbag body 1-2 to be expelled through the pressure testing three-way valves 2-8 and 2-9 and the electrically controlled valve 2-10, thereby relieving pressure on the limb's blood vessels. After pressure gauge 2-3 detects the decrease in air pressure, control board 2-7 controls electrically controlled valve 2-10 to close again and resets to await the next use.

[0030] In summary, the manual inflation automatic deflation alarm type tourniquet of the utility model, through controlling the air bag 5 to punch into the air to make the air tourniquet body 1 winding on the patient's arm expand, then through the air pressure gauge 2-3 to understand the pressure state of the air tourniquet body 1 in time, can conveniently use and control the tourniquet pressure, ensure the blood sampling smoothly, at the same time, with the help of the control panel 2-7 automatic timing of the function part 2 and the automatic deflation function of the electric control valve 2-10, can accurately control the use time and automatically release the air tourniquet body 1 after overtime, eliminate the nursing adverse events caused by forgetting to release the tourniquet, such as limb ischemic necrosis, even amputation, reduce the incidence of hemolysis of blood samples caused by long use of the tourniquet.
