[0002] Vascular surgery is a branch of surgery that primarily focuses on the prevention, diagnosis, and treatment of peripheral vascular diseases, excluding those affecting the brain and heart. Since blood vessels are distributed throughout the body except for hair, nails, and the cornea, vascular surgery covers a broad range of areas. In routine vascular surgery care, hemostasis of the patient's limbs is frequently performed. Currently, the most common method of hemostasis in vascular surgery is using bandages for pressure, which requires continuous pressure from medical staff. This is inconvenient and labor-intensive, and manual pressure application makes it difficult to control the force effectively. Utility Model Content

[0012] Beneficial effects

[0013] This invention provides a vascular surgical hemostasis aid. It has the following beneficial effects:

[0014] (1) The vascular surgical hemostasis aid device, through the cooperation between the binding strap, winding shaft, motor, limiting plate, fixing rod, first spring, movable sleeve, push plate, pressure rod and second spring, when wearing the device, after inserting the limiting plate into the internal slot, the movable sleeve automatically locks into the limiting hole, and then the motor is started to tighten the binding strap, thus completing the installation of the device. When disassembling, first release the airbag through the pressure relief valve, then press down the push plate to make the movable sleeve leave the limiting hole, and then pull out the limiting plate. The installation and disassembly of the entire device is simple and convenient, and the operation is quick.

[0015] (2) This vascular surgery hemostasis aid, through the cooperation of air pump, catheter, air bladder, diaphragm and pressure sensor, uses air pump to inflate air into the air bladder, so that the expanded air bladder applies pressure to the affected area to achieve the effect of compression hemostasis. In addition, the pressure sensor can accurately control the pressure force, which makes it convenient to continuously apply pressure to the affected area within the appropriate pressure force range. Compared with manual compression hemostasis, this device applies pressure more accurately, saves manpower and improves the hemostasis effect.

[0016] (3) The vascular surgical hemostasis aid device, through the cooperation between the septum, elastic band and elastic sleeve, may cause blood seepage during the hemostasis process. The septum can be separated from the whole device by removing the elastic sleeve from the elastic top plate, so that the septum can be cleaned separately and the device can be used multiple times.

A push plate 16 is fixedly connected to the top of the pressure rod 15. A second spring 17 is sleeved on the outer surface of the pressure rod 15. An air pump 20 and a controller 25 are fixedly connected to the upper surface of the elastic top plate 1. An air bag 18 is fixedly connected to the lower surface of the elastic top plate 1. A conduit 21 is fixedly connected to the bottom of the air pump 20. A pressure relief valve 27 is fixedly connected to the outer surface of the conduit 21. A septum 19 is provided on the lower surface of the air bag 18. An elastic band 22 is fixedly connected to the side of the outer surface of the septum 19. An elastic sleeve 23 is fixedly connected to the side of the elastic band 22 away from the septum 19. A pressure sensor 28 is fixedly connected inside the septum 19.

[0026] Specifically, the end of the binding strap 2 away from the elastic top plate 1 is fixedly connected to the outer surface of the winding shaft 3, and the end of the winding shaft 3 away from the motor 4 is rotatably connected to the inside of the take-up drum 26.

[0027] Specifically, the outer surface of the winding drum 26 is provided with a through groove 5, and the outer surface of the binding strap 2 penetrates the interior of the through groove 5.

[0028] Specifically, the outer surface of the connecting plate 9 is slidably connected to the inner surface of the movable sleeve 8, and the end of the first spring 10 away from the connecting plate 9 is fixedly connected to the top of the inner surface of the movable sleeve 8.

[0029] Specifically, the outer surfaces of the movable sleeve 8 and the pressure rod 15 are fitted to the inner surface of the limiting hole 13, the end of the second spring 17 is fixedly connected to the lower surface of the push plate 16, and the end of the second spring 17 away from the push plate 16 is fixedly connected to the upper surface of the fixing frame 14.

[0030] Specifically, the outer surface of the catheter 21 penetrates the elastic top plate 1 and extends into the inner cavity of the airbag 18, and the elastic band 22 and elastic sleeve 23 are symmetrically arranged on both sides of the septum 19.

[0031] Specifically, the elastic sleeve 23 has a groove 24 inside, and the inner surface of the groove 24 is adapted to the edge of the outer surface of the elastic top plate 1.

[0033] The working principle and beneficial effects of the above embodiments.

[0034] In use, align the diaphragm 19 with the affected area, pass the binding strap 2 through the bottom of the affected limb, and insert the limiting plate 6 into the inner slot 12. As the movable sleeve 8 moves along the inner surface of the inner slot 12, it is gradually pressed down, compressing the first spring 10. When the limiting plate 6 abuts against the innermost side of the inner slot 12, the movable sleeve 8 reaches the limiting hole 13. The elasticity of the first spring 10 causes the movable sleeve 8 to move upward to the initial height, allowing the movable sleeve 8 to insert into the limiting hole 13, thereby restricting the limiting plate 6 within the inner slot 12. The motor 4 is activated via the controller 25, driving the winding shaft 3 to rotate, causing the binding strap 2 to be wound up until it is taut. At this point, the diaphragm 19 fits against the affected area. After the device is secured, the air pump 20 is activated via the controller 25, inflating the airbag 18 through the conduit 21. The airbag 18 gradually expands, causing the diaphragm 19 to adhere to the affected area. 9. Apply pressure to the affected area. Pressure sensor 28 monitors the pressure of septum 19 on the affected area. When the preset threshold is reached, pressure sensor 28 transmits a signal to air pump 20 to stop inflation. After applying pressure to stop bleeding for a period of time, controller 25 opens pressure relief valve 27 to release the gas in airbag 18. Then press down on push plate 16, and pressure rod 15 moves accordingly. Second spring 17 is compressed, causing pressure rod 15 to push movable sleeve 8 down until movable sleeve 8 leaves limit hole 13. At this time, pull limit plate 6 outward to make limit plate 6 leave internal slot 12, unbinding the device from the affected limb and completing disassembly. When bleeding occurs, pull elastic sleeve 23 outward to disassemble the whole consisting of septum 19, elastic band 22 and elastic sleeve 23, making it convenient to clean the bloodstains adhering to septum 19. After washing and drying, it can be reinstalled and used.
