Vascular interventional therapy puncture point compression hemostasis technology is an important part of vascular intervention postoperative care, mainly including the following: Manual compression hemostasis method: This is a traditional hemostasis method. Medical staff need to press the puncture point with their fingers. The compression time is long, generally 15 to 20 minutes, but long-term compression will cause certain discomfort and pain to the patient. Mechanical compression hemostasis method: This method uses a mechanical device for compression hemostasis, which can reduce the compression time and improve the efficiency of hemostasis, but requires medical staff to have high operating skills and high equipment requirements. Vascular closure device hemostasis method: This method uses a vascular closure device to close the puncture point blood vessel to achieve the purpose of hemostasis. It has the advantages of fast, safe, and less pain, but requires medical staff to be familiar with the operation process and skills.

[0025] After the wearing tube 1 is placed near the patient's puncture point, it can be fixed by compressing the tourniquet 2, and the rotating rod 902 is rotated at the same time. When the rotating rod 902 rotates, it will drive the transmission gear plates 904 on both sides to approach each other through the transmission gear 903. At the same time, the transmission gear plates 904 drive the auxiliary compression plates 907 to approach each other through the connecting column 905, so that the auxiliary compression tourniquet 2 compresses the two sides of the puncture point, thereby compressing the main blood vessels on both sides to achieve the effect of hemostasis.

[0027] During the movement of the auxiliary mechanism 9, its bottom end will push the push blocks 1104 on both sides. When the push blocks 1104 are pushed, the lifting blocks 1105 will move upward, so that the support plate 1107 pushes the arm upward to press it. This device can completely wrap and compress the area near the puncture point by moving synchronously with the auxiliary mechanism 9, thereby reducing the difficulty of operation for personnel.

[0028] like Figure 5-6As shown, the locking mechanism 10 includes a transmission rod 1001, a transmission shift block 1002, a transmission block 1003, a movable connecting rod 1004, a transmission plate 1005, a positive magnetic plate 1006 and a negative magnetic ring 1007. The bottom end of the transmission rod 1001 is provided with a thread, the transmission block 1003 is threadedly connected to the bottom end of the transmission rod 1001, the transmission shift block 1002 is fixedly connected to the top of the transmission rod 1001, and the movable connecting rod 1004 is provided with two groups symmetrical in upper and lower directions, one end of which is hinged to the outer wall of the transmission block 1003, and the other end of which is hinged to the outer wall of the transmission block 1003. One end is hinged to the outer wall of the transmission rod 1001, and the other end of the movable connecting rod 1004 is hinged to the top of the transmission plate 1005. The outer wall of the positive magnetic plate 1006 is fixedly connected to the bottom end of the transmission plate 1005, and the inner wall of the positive magnetic plate 1006 is movably connected to the outer wall of the negative magnetic ring 1007.

A storage groove is provided on the outer wall of the rotating rod 902, and the transmission plate 1005 is movably connected to the inside of the storage groove, and the negative magnetic ring 1007 is fixedly connected to the top of the fixed connection shell 3.

[0029] By rotating the transmission rod 1001, the transmission block 1003 will be driven to move downward, and at the same time, the transmission plates 1005 on both sides will be driven to approach each other through the movable connecting rod 1004, thereby driving the positive magnetic plate 1006 to be adsorbed on the negative magnetic ring 1007, so as to achieve the limiting effect. The auxiliary mechanism 9 can be limited and fixed by the locking mechanism 10, so as to prevent the auxiliary mechanism 9 from loosening during the operation, thereby improving its stability and reducing the inconvenience caused to personnel during the operation.

[0030] Here’s how it works: When in use, after the wearing tube 1 is placed near the patient's puncture point, it can be fixed by compressing the tourniquet 2, and the rotating rod 902 is rotated at the same time. When the rotating rod 902 rotates, it will drive the transmission tooth plates 904 on both sides to approach each other through the transmission gear 903. At the same time, the transmission tooth plates 904 drive the auxiliary compression plates 907 to approach each other through the connecting column 905, so as to assist the compression tourniquet 2 to compress both sides of the puncture point, thereby compressing the main blood vessels on both sides to achieve the effect of hemostasis. During the movement of the auxiliary mechanism 9, its bottom end will push the pushing blocks 1104 on both sides. When the pushing blocks 1104 are pushed, the lifting blocks 1105 will be driven to move upward, so that the support plate 1107 pushes the arm upward to it Compression is performed, and the area near the puncture point can be completely wrapped and compressed by synchronous movement with the auxiliary mechanism 9, thereby reducing the difficulty of operation for personnel. Thereafter, the transmission rod 1001 can be rotated, and when the transmission rod 1001 rotates, it will drive the transmission block 1003 to move downward, and at the same time, the transmission plates 1005 on both sides will be driven to approach each other through the movable connecting rod 1004, thereby driving the positive magnetic plate 1006 to be adsorbed on the negative magnetic ring 1007, thereby achieving the effect of limiting. The auxiliary mechanism 9 can be limited and fixed by the locking mechanism 10, thereby preventing the medical staff from loosening the auxiliary mechanism 9 during the operation, improving its stability, and reducing the inconvenience caused to personnel during the operation.
