[0015] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0016] The present invention provides a skin ulcer dressing, comprising a dressing layer 2, an adhesive layer 1, a breathable layer 3, a water-absorbing layer 4 and a protective layer 5 made by mixing polyethylene glycol and lithospermum erythrorhizon. The adhesive layer 1, the dressing layer 2, the breathable layer 3, the water-absorbing layer 4 and the protective layer 5 are arranged in sequence and form a tooth-shaped joint structure. Since lithospermum erythrorhizon has a unique wound healing function, and lithospermum erythrorhizon can be fully dissolved in polyethylene glycol, the effective ingredients of lithospermum erythrorhizon can be fully utilized. The wound can be effectively covered and has the effects of moisturizing, anti-inflammatory, removing dead tissue and promoting tissue regeneration. It is also very effective for treating wounds such as scalds, burns, and skin ulcers. At the same time, the adhesive layer 1 is bonded to the skin. The adhesive layer 1 adopts medical adhesive. Through the water-absorbing layer 4 and the breathable layer 3, the dressing has the functions of water absorption and air permeability after being attached to the outer surface of human skin tissue. Since the adhesive layer 1, the dressing layer 2, The breathable layer 3, the water-absorbing layer 4 and the protective layer 5 are arranged in sequence and form a tooth-joint structure, that is, the adhesive layer 1, the dressing layer 2, the breathable layer 3, the water-absorbing layer 4 and the protective layer 5 are stacked at one time, and their two ends are offset and aligned respectively, that is, the adhesive layer 1, the breathable layer 3 and the protective layer 5 are parallel and aligned at both ends, the dressing layer 2 and the water-absorbing layer 4 are parallel and aligned at both ends, and the adhesive layer 1 and the dressing layer 2 are parallel and offset, and the intersection of the adhesive layer 1, the dressing layer 2, the breathable layer 3, the water-absorbing layer 4 and the protective layer 5 accounts for four-fifths of the entire skin ulcer dressing. The tooth-joint structure is used to make the two ends of the local layer not completely closed, so that each layer can better exert its characteristics to the surrounding area; for example, if the two ends of the water-absorbing layer 4 are closed by the upper and lower breathable layers 3 and the protective layer 5, it is not very convenient if the surrounding two sides need to absorb water.

[0017] At the same time, the present invention proposes a device for preparing skin ulcer dressing, including a device body 6, wherein the device body 6 has a preparation cavity, and multiple rotating motors 7 are arranged on both sides of the device body 6 in a staggered manner. Two rotating motors 7 are arranged in sequence on the left side of the device body 6, and three rotating motors are arranged in sequence on the right side of the device body 6. The output shaft of the rotating motor 7 is vertically connected to the horizontal plate 8, and the outward end of the horizontal plate 8 is fixedly connected to the output shaft. The multiple horizontal plates 8 have grooves 9 for preparing the dressing layer 2, the adhesive layer 1, the breathable layer 3, the water-absorbing layer 4 and the protective layer 5. The multiple grooves 9 corresponding to the upper and lower parallel grooves are staggered in sequence to form a tooth joint structure, and the device body 6 has a notch for conveniently rotating out the horizontal plate 8. When the raw materials for preparing the dressing layer 2, adhesive layer 1, breathable layer 3, water-absorbing layer 4 and protective layer 5 need to be poured into the groove 9, the rotary motor 7 is rotated to drive the horizontal plate 8 to rotate outward from the preparation chamber through the notch. After the raw materials are injected into the groove 9, the rotary motor 7 is controlled to drive the horizontal plate 8 to rotate from the notch into the preparation chamber, and then the same heating and cooling operations are performed in the preparation chamber. The equipment body 6 is equipped with a cabinet door, which is opened to expose the preparation chamber. Before the dressing layer 2, adhesive layer 1, breathable layer 3, water-absorbing layer 4 and protective layer 5 are completely solidified, each layer of the dressing layer 2, adhesive layer 1, breathable layer 3, water-absorbing layer 4 and protective layer 5 is taken out and then stacked together for extrusion.

[0018] The equipment body 6 is connected to the output shaft 17 of the servo motor 15. In order to facilitate the removal of the molding layer in the groove 9, the servo motor 15 is rotated to drive the equipment body 6 to rotate so that the groove 9 is opened downward and then conveniently removed. A heater 12 and a telescopic cylinder 18 are set in the preparation chamber. The heater 12 is connected to the heating plate 11. The telescopic rod 19 of the telescopic cylinder 18 is connected to the pressing plate 20. The pressing plate 20 and the heating plate 11 correspond to each other up and down. A plurality of the horizontal plates 8 are located between the pressing plate 20 and the heating plate 11. The equipment body 6 is provided with a shaft 16 corresponding to the output shaft 17. The shaft 16 is plugged into the workshop. On other fixed rods, the device body 6 is suspended and rotatable through the shaft 16 and the output shaft 17. The output shaft 17 is connected to the middle of the device body 6 and is parallel to the horizontal plate 8. The connection of the output shaft 17 is located on the back of the device body 6. Multiple rotating motors 7 are located on the left side of the device body 6. The entire preparation chamber is heated by the heating plate 11 to assist in preparation. After demoulding, the horizontal plate 8 is rotated out of the notch, and then the telescopic rod 19 is started to move the pressing plate 20 toward the heating plate 11 and then the dressing layer 2, adhesive layer 1, breathable layer 3, water-absorbing layer 4 and protective layer 5 are extruded and formed between the two.

[0019] The horizontal plate 8 is provided with a roller 10 perpendicular to the horizontal plate 8, and the diameter of the roller 10 is greater than or equal to the distance between two adjacent horizontal plates 8. The equipment body 6 is provided with an inlet 14 for rolling into the roller 10 and an outlet 13 for rolling out. The length of the roller 10 is equal to the distance between the preparation chambers. The preparation chamber is a cube. The roller 10 is put in from the inlet 14, and then the servo motor 15 is controlled to rotate forward and reverse to make the equipment body 6 swing left and right so that the roller 10 rolls down from the top horizontal plate 8 in turn through each horizontal plate 8 to smooth the raw materials in the groove 9 and finally roll out from the outlet 13. One end of the horizontal plate 8 is connected to the output shaft of the rotating motor 7, and the other section of the horizontal plate 8 is spaced from the inside of the preparation chamber by a distance greater than the diameter of the roller 10. When demolding is required, the equipment body 6 is reversed so that the groove 9 opening faces downward, and then the roller 10 is put in from the outlet 13 and then the roller 10 hits the horizontal plate 8 to facilitate demolding.

[0020] The depths of the multiple grooves 9 correspond to the thicknesses of the dressing layer 2, the adhesive layer 1, the breathable layer 3, the water-absorbing layer 4 and the protective layer 5, respectively. Another section of the horizontal plate 8 corresponding to the output shaft has a convex edge 22, which forms the side of the groove 9. The convex edge 22 has an open ultrasonic groove 21, and the excess raw material is driven by the roller 10 to flow into the groove 21 for storage; the depth of the groove 9 is between 0.1 and 0.5 mm.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
