[0023] See attached Figure 1-5The utility model provides a negative pressure drainage device for skin ulcers, including a filling dressing 100. The filling dressing 100 is used to fill the wound opened by the patient. The skin patch 200 can make the insertion end of the suction tube 300 closed, which is convenient for generating negative pressure in the wound later. The filling dressing 100 can use medical collagen sponge as a dressing. The medical collagen sponge uses bovine Achilles tendon as a raw material to obtain collagen after biological purification. It is a white sponge-like solid and is sterilized by cobalt 60 radiation. Sponges are suitable for filling surgical residual cavities, stopping bleeding on wounds, and promoting wound healing. Medical collagen sponges are used as dressings, which can temporarily protect wounds, prevent contamination, and promote healing. They can adhere closely to the wound surface, have good affinity, and can adhere to the wound surface evenly and tightly. They can prevent the loss of body fluids and water, resist bacterial invasion, and prevent infection. They can absorb exudate flowing out of the wound surface without causing fluid accumulation between the dressing and the wound surface, thus alleviating pain. They can maintain and promote the normal growth of granulation tissue and epithelial tissue, promote wound healing, and leave no scars.It has certain mechanical strength, is soft, and does not deform. A skin patch 200 for closing the wound is arranged on the top of the outer wall of the filling dressing 100, and the arranged skin patch 200 can be made of flexible silicone. When in use, the skin patch 200 can be closely attached to healthy skin, and the periphery of the skin patch 200 is thinned. At the same time, a transparent adhesive film can be arranged between the bottom surface of the skin patch 200 and the filling dressing 100, so as to ensure that the skin patch 200 can seal the filling dressing 100 and the wound. One end of the pipette 320 is inserted into the filling dressing 100 and is connected to the pipette port 300. The side end of the outer wall of the pipette port 300 is penetrated by a pipette hole 310, and a plurality of pipette holes 320 are arranged. 10 are uniformly arranged in a circular array. Specifically, the front end of the suction pipe opening 300 is conically arranged, so that it is convenient for personnel to pass the suction pipe opening 300 through the filling dressing 100, and the suction hole 310 is opened to enable the suction pipe opening 300 to absorb pus from the wound. A suction pipe 320 for suction is plugged into the filling dressing 100, and a drainage pipe 330 is arranged at one end of the suction pipe 320 away from the filling dressing 100. The suction pipe 320 and the drainage pipe 330 are connected through a connecting component. The suction pipe 320 can be used to be fixed at the wound, and the drainage pipe 330 is used to drain the suction pipe 320. 0 For the subsequent delivery of the pus, the connecting component includes a connecting plug 321 and a connecting sleeve 331. The connecting plug 321 is connected to the end of the suction tube 320 away from the filling dressing 100, and the connecting sleeve 331 is connected to the end of the drainage tube 330 close to the suction tube 320. By plugging the connecting plug 321 and the drainage tube 330, the connecting plug 321 and the drainage tube 330 are connected, so that the pus in the suction tube 320 can enter the drainage tube 330 through the connecting plug 321. The outer wall of the connecting plug 321 is slidably connected to the inner wall of the connecting sleeve 331, and the outer wall side end of the connecting plug 321 is surrounded and fixed with an outer clamp ring 322 The arc-shaped clamping block 332 for clamping is fixed on the inner wall side end of the connecting sleeve 331 and on one side of the outer clamping ring 322. The multiple arc-shaped clamping blocks 332 are evenly arranged in a circular array. The arc-shaped clamping block 332 and the outer clamping ring 322 are provided so that after the personnel insert the connecting plug 321 into the connecting sleeve 331, the arc-shaped clamping block 332 can clamp the side wall of the outer clamping ring 322, so that the connecting plug 321 can be prevented from separating from the connecting sleeve 331 without the action of external force. The materials of the arranged pipette 320, the connecting plug 321, the drain pipe 330 and the connecting sleeve 331 are all made of sterile medical silicone.
[0024] A sealing tube component is provided on the outer wall of the pipette 320 and at one end close to the connecting component. The sealing tube component is provided to clamp the outer wall of the pipette 320 when the personnel replaces the drainage tube 330 to prevent pus leakage. The sealing tube component includes a pipeline clamp 400. Grooves are provided on both sides of the outer wall of the pipeline clamp 400 and at positions corresponding to the pipette 320. The outer wall of the pipette 320 is connected to the inner wall of the groove. A roller 410 is rotatably connected to the inner wall of the pipeline clamp 400 and is located on one side of the pipette 320. An eccentric wheel 420 is fixed on the outer wall of the roller 410 and at a position corresponding to the pipette 320 A handle 430 is fixed to the top of the outer wall of the roller 410 and passes through the top of the outer wall of the pipette block 400. The pipe block 400 can be fixed to the outer wall of the pipette 320 through a groove. When the pipette 320 needs to be clamped, the personnel can rotate the roller 410 through the handle 430. The roller 410 can drive the eccentric wheel 420 to rotate when rotating. When the eccentric wheel 420 rotates, the raised end of the eccentric wheel 420 will abut against the side wall of the pipette 320, so that the pipette 320 can be clamped to shrink, so that the pipette 320 can be closed to prevent the pus in the pipette 320 from leaking.
[0025] The use process of the utility model is as follows: first, the medical staff can clean the wound of the patient, then take out the filling dressing 100 with the suction tube port 300 inserted in advance, and then place the filling dressing 100 on the wound to fill the wound. After the filling is completed, the skin patch 200 is covered on the filling dressing 100 to seal the filling dressing 100. After completion, the drainage tube 330 can be taken out, and the connecting plug 321 is inserted into the inner wall of the connecting sleeve 331, so that the arc-shaped clamping block 332 can clamp the side wall of the outer clamping ring 322, so that The connecting sleeve 331 can be fixed with the connecting plug 321, and the connecting plug 321 will communicate with the inner wall of the drainage pipe 330 after being inserted into the connecting sleeve 331. After completion, the personnel can connect the negative pressure pump to the other end of the drainage pipe 330, and the drainage pipe 330 and the suction pipe 320 form a negative pressure state on the wound through the negative pressure pump. Then, under the negative pressure environment, the pus generated in the wound can enter the suction pipe port 300 and the suction pipe 320 through the suction hole 310, and finally be transported to the waste liquid bag through the drainage pipe 330 for storage;
[0026] When the drainage tube 330 is damaged and needs to be replaced, the personnel can rotate the roller 410 through the handle 430, and the roller 410 can drive the eccentric wheel 420 to rotate when rotating. When the eccentric wheel 420 rotates, the raised end of the eccentric wheel 420 will abut against the side wall of the suction tube 320, thereby clamping the suction tube 320 to make it contract, thereby sealing the suction tube 320 to prevent the pus in the suction tube 320 from leaking, and then the drainage tube 330 and the suction tube 320 can be grasped at both ends to separate the connecting plug 321 from the connecting sleeve 331, and finally the new drainage tube 330 is taken out and connected to the connecting plug 321, and then the roller 410 is rotated to make the eccentric wheel 420 rotate to cancel the locking of the suction tube 320, and then the suction tube 320 can continue to transport pus.
