DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application embodiment discloses a combined wound care material set, comprising a first water-absorbing layer 1, a second water-absorbing layer 2, a negative pressure drainage tube 5, and a closed film 4. The first water-absorbing layer 1 and the second water-absorbing layer 2 are made of water-absorbing fibers, and in this embodiment, the water-absorbing fibers are specifically medical polyurethane. The first water-absorbing layer 1 and the second water-absorbing layer 2 generally have the same area and are smaller than the area of ​​the closed film 4, and the closed film 4 is a polyurethane film.

[0027] The side wall at one end of the negative pressure drainage tube 5 has a plurality of liquid inlet holes 3, and the liquid inlet holes 3 are distributed along the circumferential direction of the negative pressure drainage tube 5. A flushing hole 51 is provided at the side wall at the other end of the negative pressure drainage tube 5, and the diameter of the flushing hole 51 is consistent with the diameter of the flushing tube 6. The center line of the flushing hole 51 is set at an acute angle to the center line of the negative pressure drainage tube 5. The flushing hole 51 is connected to the flushing tube 6, and the diameter of the flushing hole 51 is consistent with the diameter of the flushing tube 6. A sealing plug 61 is installed at one end of the flushing tube 6 away from the negative pressure drainage tube 5, and the sealing plug 61 is fixed to the flushing tube 6 through a connecting strip 62.

[0028] Specifically, the flushing tube 6 is inserted into the flushing hole 51, and a hollow annular ring 63 is fixed on the flushing tube 6, and the hollow annular ring 63 is filled with glue. A cutting piece 53 is fixed on the outer wall of the negative pressure drainage tube 5, and the cutting piece 53 is located next to the flushing hole 51. An annular retaining ring 52 is fixed on the outer wall of the negative pressure drainage tube 5, and the diameter of the annular retaining ring 52 is larger than the diameter of the flushing hole 51, and the annular retaining ring 52 surrounds the flushing hole 51, and the cutting piece 53 is located inside the annular retaining ring 52, and the height of the cutting piece 53 is less than the height of the annular retaining ring 52.

[0029] One end of the negative pressure drainage tube 5 with a liquid inlet hole is inserted into the interlayer between the first water absorbing layer 1 and the second water absorbing layer 2 , and the closing film 4 covers the first water absorbing layer 1 and the area of ​​the closing film 4 is larger than that of the first water absorbing layer 1 .

[0030] A limit guide 7 is fixed inside the negative pressure drainage tube 5 at the flushing hole 51, and its cross section is a right triangle. The limit guide 7 has a guide slope 71 and a vertical limit surface 72. When the flushing tube 6 is inserted and abuts against the vertical limit surface 72, the cutting blade 53 is inserted into the annular ring, and the flushing tube 6 is rotated appropriately to ensure that the hollow annular ring 63 is cut with enough holes for the glue to flow out, and then the glue that flows out is blocked by the annular retaining ring 52 and solidified to fix the flushing tube 6.

[0031] When in use, the closing film 4 covers the first water absorbing layer 1 and the second water absorbing layer 2 and is in close contact with the skin. The closing film 4 can be fixed with tape, or adhesive can be set around the edge of the closing film 4 (the same as the adhesive on the band-aid), and the negative pressure drainage tube 5 is connected to the negative pressure drainage machine.
