[0002] Acute kidney injury (AKI) is a clinical syndrome caused by a rapid decline in kidney function over a short period of time due to various etiologies, resulting in azotemia, electrolyte and acid-base imbalances, and symptoms in various systems of the body.

[0003] After dialysis puncture treatment for AKI patients, it is usually necessary to use a compression device to assist in hemostasis after the puncture needle is removed. However, conventional compression devices can obstruct the view of the wound and the cotton ball during use, making it difficult for medical staff to directly observe the coverage position and blood absorption status of the cotton ball from the outside. As a result, it is impossible to detect in time whether there is a risk of bleeding from the wound, which brings significant inconvenience to clinical operation. Summary of the Invention

[0033] Working principle: In use, insert the needle into the rubber stopper 310 with a syringe and inject pure water to initially fill the interior of the rubber compression fluid bladder 101 and the light-transmitting cover 103. After filling, remove the needle and the rubber stopper 310 self-seales. Then, press the rubber compression fluid bladder 101 onto the cotton ball on the wound surface to restrict the cotton ball inside the limiting isolation cotton ring 307. Then, attach the ring-shaped medical tape 311 to the skin surface around the wound to initially fix the device. Then the second strap 412 and the first strap 410 are wrapped around the patient's waist. The second strap 412 passes through the docking loop 411 and is then secured to the device by the Velcro group 414. Then, insert the syringe needle back into the rubber stopper 310, inject or draw water through the syringe, and use the hydraulic gauge 308 to adjust the pressure of the rubber compression fluid bladder 101. After adjustment, pull out the needle, the rubber stopper 310 self-seales, and turn on the switch of the supplementary light ring 104 to make it powered on and emit light. After a period of time, if there is no bleeding, then the surface condition of the bleeding control photo 203 is normal. If there is bleeding, the blood will penetrate the cotton ball and pass through the bleeding hole 202. After passing through the bleeding hole 202, the blood will seep into the bleeding control photo 203, thus forming a red blood spot inside the marking control counting circle 204. If the amount of blood penetration is small, the number of blood spots inside the marking control counting circle 204 will be small and fewer. If the amount of blood penetration is large, the opposite will be true. At the same time, if the amount of bleeding is particularly large, the outer ring of the blood spot will touch the marking control concentric circle 205. The greater the amount of bleeding, the further out the marking control concentric circle 205 will be touched. Therefore, the bleeding situation can be obtained by counting the amount of bleeding inside the marking control counting circle 204 and the range of blood spots inside the marking control counting circle 204 and the marking control concentric circle 205. When blood spots appear, the light-transmitting cover 103 and the pure water inside form a convex lens effect, which magnifies the blood spots to a certain extent. The blood seepage improves the contrast effect on the white background of the photo 203, and the supplementary light ring 104 increases the brightness, thus jointly improving the clarity when observing blood spots. When disassembling the fastening mechanism, press the anti-detachment block 404 to retract the anti-detachment block 404 into the receiving cavity 402, and the anti-detachment block 404 will stop blocking one side of the hanging post 403. Then slide the hanging ring 407 towards the middle to disengage the hanging ring 407 from the surface of the hanging post 403, thereby realizing the disassembly of the fastening mechanism. When installing the fastening mechanism, press the anti-detachment block 404 to retract it into the receiving cavity 402, thus releasing the obstruction of the anti-detachment block 404 on one side of the hanging post 403. Then, put the hanging ring 407 on the surface of the hanging post 403, and then release the pressure on the anti-detachment block 404. The anti-detachment block 404 is pushed back to its original position by the rebound of the compression spring 405, thereby limiting the hanging ring 407 at the end of the hanging post 403 to prevent it from detaching.
