in the process of binding a wound of a patient by medical workers, in order to ensure the binding effect, gauze needs to be bound into a tight state, but when the gauze is tight, large pressure can be generated on the wound of the patient, so that blood at the wound can permeate through the gauze, and liquid medicine at the wound can also permeate into the gauze, thereby affecting the treatment effect on the patient, after a plurality of arc-shaped grooves 21 are uniformly formed on the side wall of the cotton pad 2 close to the mesh cloth 1, most of the blood and the medicine which are permeated under pressure can flow to the arc-shaped grooves 21, thereby temporarily storing the blood and the medicine, avoiding infection caused by the fact that the blood permeates to the surface of the gauze, and avoiding the influence on the treatment of the wound of the patient after the medicine flows away; when medical personnel need to wrap the wound of a patient by using gauze, pressure is only required to be applied to the pressing plate 4, the pressing plate 4 transmits the pressure to the overlapped air bag 5, the internal gas of the overlapped air bag 5 after being pressed is transmitted to the piston cylinder 71 through the hose, the output end of the piston cylinder 71 is pushed to extend, so that the T-shaped rod 74 is pushed through the conical block 72, the T-shaped rod 74 drives the clamping block 73 to slide towards the direction close to the side wall of the cavity 31 after being pushed, and at the moment, the clamping block 73 is not attached to the gauze any more; the medical staff can optionally pull the gauze, after the gauze is bound, the medical staff only needs to loosen the pressing block, the piston cylinder 71 drives the conical block 72 to reset, the T-shaped rod 74 also resets under the elastic action of the spring, and the clamping block 73 is close to the gauze again to fix the position of the gauze; therefore, great convenience is brought to binding of medical workers, when the medical workers are bound, only the shell 3 is needed to be held by hands and tensile force is generated, the reel 6 can drive the gauze to rotate, so that the gauze is supplied, the medical workers can operate with one hand, and when the gauze is not needed to be used, the gauze can be effectively protected in the shell 3, the contact between the gauze and the outside air is reduced, and the breeding of bacteria on the surface of the gauze is reduced; when a medical worker applies pressure to the pressing plate 4, the pressing plate 4 transmits the pressure to the overlapped air bag 5, part of air in the overlapped air bag 5 is transmitted into the rubber tube 81 after being pressed, so that the rubber tube 81 is pressed to be stretched and deformed, and thrust is generated on the first plate 82; after binding is completed, medical staff loosens the pressing plate 4, the rubber tube 81 is elastically restored, and the friction force borne by the second plate 83 is larger than that of the first plate 82, so that the second plate 83 rotates before sliding, the hinged rod 84 drives the scraper 85 to slide in the direction close to the backing plate 322 in the rotating process of the hinged rod 84, until the scraper 85 supports gauze on the surface of the backing plate 322, pressure is continuously applied to drive the second plate 83 to slide, the scraper 85 generates cutting force on the gauze in the sliding process of the second plate 83, and when the rubber tube 81 completes elastic restoration, the scraper 85 completes cutting on the gauze, so that the gauze is automatically cut off, and great convenience is brought to the operation of the medical staff; when medical care personnel need to wrap a wound of a patient by using gauze, pressure is only required to be applied to the pressing plate 4, the pressing plate 4 transmits the pressure to the laminated air bag 5, the internal gas of the laminated air bag 5 is transmitted to the piston cylinder 71 through the hose after being pressed, the output end of the piston cylinder 71 is pushed to extend, so that thrust is generated on the T-shaped rod 74 through the conical block 72, the T-shaped rod 74 drives the fixture block 73 to slide in the direction close to the side wall of the cavity 31 after being pushed, at the moment, the fixture block 73 is not attached to the gauze any more, the medical care personnel can randomly pull the gauze, when the fixture block 73 slides in the direction close to the side wall of the cavity 31, the side wall of the fixture block 73 extrudes the water bag 311, the disinfection alcohol in the water bag 311 is sprayed out through the one-way valve port 312 after being pressed, the disinfection alcohol is dripped on the surface of the gauze, thereby realizing the disinfection effect on the, thereby further ensuring the cleanliness of the gauze; after the dressing is finished, medical personnel only need to loosen the pressing block, the piston cylinder 71 drives the conical block 72 to reset, the T-shaped rod 74 also resets under the elastic force of the spring, and the clamping block 73 is pressed close to the gauze again to fix the position of the gauze; because the gauze surface has a plurality of meshs, drive cockscomb structure clutch blocks 731 at fixture block 73 and hug closely the gauze, when realizing the fixed to the gauze, cockscomb structure clutch blocks 731 is very easily inserted in the meshs to cause the destruction to the gauze structure, influence the whole result of use of gauze, consequently be equipped with the arc chamfer with cockscomb structure clutch blocks 731 tip, thereby effectively avoided the destruction that cockscomb structure clutch blocks 731 caused the gauze, further strengthened gauze spool 6's whole result of use.
