The limb artery tourniquet 1 is a medical tool for first aid, mainly used to stop bleeding by compressing arteries in case of severe bleeding, preventing shock or death caused by excessive blood loss. The tourniquet 1 is usually used for severe bleeding in the limbs. By physically compressing blood vessels, it stops the blood from flowing to the injured part. However, it is found during the use of the tourniquet 1 that when the tourniquet 1 tightens the patient's limb part, when the patient moves the limb, the elastic band will loosen. The hemostatic effect of the loosened tourniquet 1 will be affected, and the hemostatic stability of the tourniquet 1 will be reduced. At this time, the pressing mechanism 2 can be used to cooperate with the tourniquet 1 to perform the hemostasis task.

One end of the arc surface of the rotating rod 34 is fixedly connected to a rotating block 35. When it is necessary to change the size of the contact clip 212, the contact clip 212 can be replaced through the replacement mechanism 3. Through the replacement mechanism 3, contact clips 212 of different sizes can be replaced to improve the stability of the entire pressing mechanism 2 in contact with the patient's limb and enhance the hemostasis effect. A plurality of anti-slip grooves 36 are formed at one end of the arc surface of the rotating block 35. The plurality of anti-slip grooves 36 are evenly distributed on the rotating block 35.

[0050] Its overall working principle is as follows: The hemostatic frame 202 is brought into contact with the limb part of the patient. At this time, the tourniquet 1 can be pulled in the adjustment hole 203. The movement of the tourniquet 1 will drive the connecting rod 201 to rotate within the hemostatic frame 202. By pulling the tourniquet 1, the hook-and-loop fastener male part 204 installed on the tourniquet 1 is connected to the hook-and-loop fastener female part 205 installed on the hemostatic frame 202. At this time, the tourniquet 1 can be fixed on one side of the hemostatic frame 202. The adjustment plate 209 is rotated on the support rod 208. The movement of the adjustment plate 209 will drive the first spring 210 to move. At this time, the fixing effect of the adjustment plate 209 and the limit block 211 on the adjustment rod 206 can be released. At this time, the height of the adjustment rod 206 can be adjusted within the hemostatic frame 202. When the contact clip 212 installed on the adjustment plate 209 comes into contact with the limb of the patient, the adjustment plate 209 can be released. The reset of the first spring 210 can drive the adjustment plate 209 to rotate on the support rod 208. At this time, the limit block 211 can be driven by the adjustment plate 209 to connect with the inner wall of the adjustment groove 207. At this time, the position of the adjustment plate 209 can be fixed by connecting the limit block 211 with the inner wall of the adjustment groove 207. The connecting block 214 installed on the connecting rod 213 can improve the speed and efficiency of pressing the adjustment plate 209. The fixing block 216 can improve the speed of adjusting the adjustment rod 206. The connecting block 215 can improve the speed and efficiency of pulling the tourniquet 1.

[0051] Rotate the rotating block 35. The movement of the rotating block 35 will drive the rotating rod 34 to rotate within the mounting hole 32. At this time, the rotating rod 34 can be rotated out of the mounting hole 32 through the rotating block 35. At this time, the fixing effect of the rotating rod 34 on the mounting block 33 and the connecting ring 31 can be released. At this time, the connecting ring 31 can be removed from the mounting block 33. Then, the connecting ring 31 of the contact clip 212 with the required size can be detached from the adjustment rod 206 together with the contact clip 212. The inner wall of the connecting ring 31 of the contact clip 212 with the required size is connected to the surface of the mounting block 33. At this time, the rotating rod 34 can be rotated through the rotating block 35 within the mounting hole 32. Then, the connecting ring 31 can be fixed on the mounting block 33 through the rotating rod 34. At this time, the contact clip 212 with the required size that needs to be replaced can be fixed on the adjustment rod 206. The anti-slip groove 36 can increase the friction force on the surface of the rotating block 35. The auxiliary block 37 can improve the connection speed between the mounting block 33 and the inner wall of the connecting ring 31. The protective ring can prevent the connecting ring 31 from directly contacting the adjustment rod 206, and the protective ring can protect the contact position between the connecting ring 31 and the adjustment rod 206.

[0052] Pull the limiting rod 44 through the pull ring 49. The movement of the limiting rod 44 will drive the second spring 45 to stretch. At this time, the airbag 42 can be placed in the connecting groove 41. At this time, the contact rod 46 installed on the airbag 42 can be connected to the inner wall of the positioning rod 47. At this time, the limiting rod 44 will be aligned with the inner wall of the hemostatic frame 202. Then release the pull ring 49. The reset of the second spring 45 can drive the limiting rod 44 to be connected to the inner wall of the hemostatic frame 202 through the connecting plate 43. Through the connection between the limiting rod 44 and the inner wall of the hemostatic frame 202, the airbag 42 can be fixed in the connecting groove 41. The friction pad 48 can increase the friction force between the airbag 42 and the patient's limb.
