The arteriovenous fistula, which is the lifeline of hemodialysis patients, needs to be punctured repeatedly, so it is inevitable that the puncture site will bleed during treatment. Most of the puncture eye patches currently in use are opaque, and it is impossible to directly observe whether there is bleeding at the puncture site and whether the needle has slipped. Therefore, it is necessary to repeatedly lift the patch at the puncture site to check, which is likely to cause certain contamination risks to the puncture site. Most of the puncture eye patches on the market have poor absorbency, and even a small amount of bleeding is difficult to absorb. In addition, the hemostatic effect is weak, and there is no corresponding hemostatic means. When bleeding occurs at the puncture site, it is necessary to use additional sterile cotton balls and gauze and other pressure bandages to control the bleeding. Utility Model Content

[0031] Combine Figure 8 、 Figure 9 、 Figure 10 As shown, the compression airbag 3 is hemispherical, and its bottom surface is fixed at the center of the contact surface of the adhesive patch 1. The hemostasis effect is controlled by injecting and extracting the gas in the compression airbag 3. The compression airbag 3 includes a shell 31, an airbag 32, a bag mouth 33, a button 34, a connecting rod 35, a baffle 36 and a spring 37. The shell 31 is fixedly connected to the contact surface of the adhesive patch 1, and the airbag 32 is arranged between the shell 31 and the contact surface of the adhesive patch 1. The bag mouth 33 is installed on the airbag 32, and the bag mouth 33 extends through the shell 31 to the outside of the shell 31. When the bag mouth 33 is not operated, it can maintain the air pressure inside the airbag 32. When the bag mouth 33 is connected to a syringe, the syringe can inject or extract gas so that the air pressure inside the airbag 32 increases or decreases. The shell 31 is rigid. When the air pressure inside the airbag 32 increases, the shell 31 is used to transfer the pressure of the airbag 32 to the contact surface of the adhesive patch 1, so that the contact surface of the adhesive patch 1 applies pressure to the application 2 to prevent bleeding;

[0032] The upper part of the bag mouth 33 is a hollow cylinder. The lower part of the bag mouth 33 is provided with two through holes whose axes are parallel to the central axis of the bag mouth 33. One of the through holes is located at the central axis of the bag mouth 33, and the button 34 is located on the other through hole. The baffle 36 is located on the bottom end plane of the bag mouth 33 and the axis of the baffle 36 coincides with the axis of the bag mouth 33. The connecting rod 35 is fixedly connected to the button 34 and the baffle 36 respectively. When the bottom surface of the button 34 coincides with the bottom surface of the central channel at the upper part of the bag mouth 33, the baffle 36 is opened. The upper surface of the plate 36 coincides with the bottom surface of the bag mouth 33, so that the interior of the airbag 32 is in a sealed state. A crossbeam is provided inside the airbag 32, perpendicular to the axis of the bag mouth 33. The crossbeam has a through hole parallel to the axis of the bag mouth 33. The connecting rod 35 has a downwardly extending end that coincides with the axis of the button 34. One end of the spring 37 is fixed to the crossbeam. The extended end of the connecting rod 35 passes through the central axis of the spring 37 and is inserted into the through hole of the crossbeam.

[0033] The diameter of the central channel at the upper part of the bag nozzle 33 is equal to the outer diameter of the syringe barrel, and the diameter of the central through hole in the bag nozzle 33 is equal to the outer diameter of the syringe needle. The inclined bag nozzle 33 facilitates the insertion of the syringe into the bag nozzle 33. When the needle of the syringe is inserted into the through hole in the center of the bag nozzle 33, the syringe will press the button 34, and the button 34 will drive the connecting rod 35 to slide downward. The extended end of the connecting rod 35 is inserted from the cross beam inside the airbag 32, and the connecting rod 35 drives the baffle 36 to move downward from the bottom end of the bag nozzle 33. At this time, the spring 37 is compressed. When the syringe leaves the bag nozzle 33, the spring 37 recovers, thereby driving the connecting rod 35 to push the button 34 and the baffle 36 to their original position. The diameter of the baffle 36 is larger than the central through hole of the bag nozzle 33, ensuring that the baffle 36 blocks the central through hole of the bag nozzle 33 when the spring 37 recovers.

[0034] The adhesive patch 1, the dressing 2 and the compression airbag 3 are all made of transparent materials, which can monitor in real time whether there is bleeding at the needle hole and whether the needle slips.

[0035] This embodiment has a good bonding density, and the puncture needle eye can be directly pressed with gauze and the puncture needle can be pulled out. There is no need to tear off the original adhesive tape, disinfect the puncture needle eye, and apply a band-aid before pulling out the needle, thereby avoiding contamination of the puncture needle eye by the external environment during the process of pulling out the puncture needle.

[0036] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
