[0002] Negative pressure wound therapy technology is a wound therapy method with wide clinical application. It usually covers the wound with a sponge dressing with a drainage tube, and then seals it with a film. The drainage tube is connected to a negative pressure source to put the local area in a negative pressure environment, and the necrotic tissue and exudate in the wound are discharged from the body through the drainage tube, creating a good growth environment for wound repair and subsequent recovery.

[0003] Chinese patent announcement number CN216148341U discloses a negative pressure liquid absorption dressing device, including a suction device and a dressing body, the suction device including a suction cup pipeline and a suction cup connected to the suction cup pipeline, the dressing body including a wound contact layer, a liquid transmission layer, an absorption layer, and a film arranged in sequence from bottom to top; a suction hole penetrating the absorption layer and the film is provided on the dressing body, a liquid blocking layer is provided at the bottom of the suction cup of the suction device, a sealing layer is provided at the bottom of the liquid blocking layer, and the suction cup cover of the suction device is provided on the suction hole of the dressing body. The suction device pipeline of the negative pressure liquid absorption dressing provided by the utility model is pressure-resistant and soft, and the installation process of the sealing layer and the water blocking layer is excellent, which can ensure that the exudate is isolated inside the dressing after negative pressure suction and is not sucked out, and will not cause damage to the negative pressure pump. At the same time, the absorbed exudate will not infiltrate back to the wound surface, causing secondary infection of the wound surface. The dressing body adopts highly absorbent fiber to form a gel with the exudate, and a better effect can be achieved without a drainage bottle.
