Negative pressure sealing drainage device and operation method

The invention relates to a negative pressure sealing drainage device and an operation method, which belong to the technical field of medical apparatus and instruments. Multi-shaped foam and a negative pressure pipe clamping technology are adopted; a top end section of a flushing pipe is placed under the foam; a clamping seam on the foam is in clamp connection with the top end section of a negative pressure pipe; the upper part of the foam clamped with the negative pressure pipe is bonded with a thin film; the outer end of the negative pressure pipe is fixed with a negative pressure pump, the outer end of the flushing pipe, and a syringe; the lower part of the foam bonded with the thin film and the flushing pipe connected to the lower part of the foam are placed on a seepage body; and the thin film on the periphery of the foam is bonded with the seepage body. The method comprises the following steps of: making the foam, setting the clamping seam, clamping the negative pressure pipe, placing the flushing pipe, clamping the foam clamped with the negative pressure pipe, making a seepage body sealing space, fixing the negative pressure pump and the syringe, carrying out negative pressure sealing drainage operation, flushing, and finishing the negative pressure sealing drainage operation. The negative pressure sealing drainage device is used for suctioning skin exudate, has a scientific concept and an ingenious structure, is material-saving, power-saving and labor-saving, is flexible and convenient to use, has a stable and reliable effect, and overcomes the existing technical defects.
