When the patient's wound needs to stop bleeding, the spherical compression pad 13 is first placed on the patient's wound, and then the limiting plate 16 on the knob 14 is rotated inside the limiting groove 17. During this process, the rotating rod 15 moves inside the limiting hole 12 and drives the spherical compression pad 13 to squeeze the patient's wound, so as to stop bleeding from the patient's wound, thereby improving the convenience of the tourniquet during use; A blood cooling device is installed on the spherical compression pad 13, and the blood cooling device includes a metal plate 18, a semiconductor refrigeration sheet 19, a cooling chamber 20, a heat sink 21 and a cooling fan 22. The metal plate 18 is connected to the heat sink 21 through the semiconductor refrigeration sheet 19, and the cooling fan 22 is installed at the other end of the heat sink 21. The semiconductor refrigeration sheet 19, the heat sink 21 and the cooling fan 22 are electrically connected to the control mechanism 23 through a conductive wire 33. Pressure sensors are installed on both sides of the bottom of the cooling chamber 20. One end of the metal plate 18 is located inside the cooling chamber 20, and the other end of the metal plate 18 is sealed and connected to the inside of the spherical compression pad 13 and is flush with its upper surface. The cooling end of the semiconductor refrigeration sheet 19 is bonded to the other end of the metal plate 18 through silicone, and the other end of the semiconductor refrigeration sheet 19 is bonded to one end of the heat sink 21 through silicone. One end of the cooling fan 22 is against the other end of the heat sink 21 and is connected to the spherical compression pad 13 through bolts. The pad 13 is fixedly connected, and the conductive wire 33 is inserted into the interior of the rotating rod 15.

The pressure sensor 24 is fixedly connected to the interior of the spherical compression pad 13, and its detection end is downward. The pressure sensor 24 is separated from the cooling chamber 20. When a tourniquet is used to stop bleeding on a patient, the control mechanism 23 first controls the semiconductor cooling plate 19, the heat sink 21 and the cooling fan 22 to operate. At this time, the cooling end of the semiconductor cooling plate 19 will cool the water in the cooling chamber 20 through the metal plate 18. In this process, the heat sink 21 will absorb the heat from the heat release end of the semiconductor cooling plate 19, and then it will be cooled by the cooling fan 22, and then the spherical compression pad 13 will contact the patient's wound, so as to achieve cooling of the patient's wound, slow down the blood flow rate at the patient's wound, and reduce the patient's pain during hemostasis.

[0021] Specifically, three locking holes 25 are opened at the edge of the support plate 1, and three straps 11 are provided. One end of the three straps 11 is sleeved in the locking holes 25, which improves the firmness of the tourniquet when installed on the patient's body.

[0022] Furthermore, three abutting columns 27 are connected to the edge of the bottom of the support plate 1 through three threaded joints 26, and the other end of the abutting column 27 is connected to a threaded adjustment column 29 through a threaded groove 28. A stabilizing pad 30 is installed on the other end of the threaded adjustment column 29. One end of the three threaded joints 26 is connected to the interior of the support plate 1 through threads, and the other end of the three threaded joints 26 is fixedly connected to one end of the three abutting columns 27. The threaded groove 28 is located inside the other end of the abutting column 27. One end of the threaded adjustment column 29 is connected to the interior of the threaded groove 28 through threads. The threaded adjustment column 29 is connected to the interior of the threaded groove 28 through threads. The other end of the column 29 is fixedly connected to one end of the stabilizing pad 30. When the tourniquet is used, the stabilizing pad 30 on the three abutting columns 27 is first adjusted according to the position of the patient's body. At this time, the operator rotates the stabilizing pad 30, so that the threaded adjustment column 29 rotates inside the threaded groove 28, so that the support plate 1 can remain parallel to the patient's body when the stabilizing pad 30 contacts the patient's body, thereby making the tourniquet uniform when subjected to force on the patient's body, avoiding the phenomenon that the force point of the tourniquet is at a certain point on the patient's body, causing discomfort to the patient.

[0023] Furthermore, the control mechanism 23 is fixedly connected to one side of the upper surface of the support plate 1, and an OLED display screen 31 is installed on the upper surface of the control mechanism 23. A control button 32 is installed on one side of the OLED display screen 31, which allows the operator to observe the patient's compression condition in real time through the OLED display screen 31.

[0024] It is worth noting that the support plate 1 is made of transparent PC or ABS material, the spherical compression pad 13 is made of silicone material, and the strap 11 is made of nylon material, which improves the wear resistance and comfort of the tourniquet during use.

[0025] It should be noted that the control mechanism 23 includes a single-chip microcomputer (STC8 series), which is battery-powered.

First, the hemostatic device is fixed at the hemostatic position of the puncture point, and the control button 32 is operated. The pressure display range is 0-400mmHg, and the time setting range is 0-600min. The strap 11 is tightened by the pressurizing device to cause the spherical silicone pad to press the hemostatic position. When the required pressure is reached, the pressurization is stopped. Press and hold the button for 5s, and the countdown starts. The OLED display 31 displays the pressure and countdown time in real time. When the set time is reached, the buzzer alarms and emits a beep to remind the patient to remove the tourniquet.
