Description

Technical Field

[0001] This utility model relates to the field of healing device technology, specifically a wound-aiding healing device. Background Technology

[0002] Wound healing devices are equipment or materials used to promote wound healing by providing appropriate environment and conditions to accelerate the wound healing process.

[0003] Common healing devices typically use a patch to cover the wound to promote healing, a protective layer, and then wrap it with medical gauze.

[0004] However, when the auxiliary healing device is applied to the wound, the body fluid at the wound site is squeezed out and flows out. After prolonged contact with the body fluid, the patch becomes filled with body fluid, resulting in poor absorption of body fluid. This causes the body fluid to easily flow to the adhesive area, reducing the sealing stability of the auxiliary healing device and also reducing the healing effect on the wound. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a wound-aiding healing device. This addresses the problem mentioned in the background art where, when the aiding healing device is applied to a wound, bodily fluids at the wound site are squeezed out, and after prolonged contact with bodily fluids, the patch becomes saturated with fluids, resulting in poor fluid absorption. Consequently, the fluids easily flow to the adhesive area, reducing the sealing stability of the aiding healing device and also decreasing the wound-healing effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wound-aiding healing device, comprising:

[0009] The patch section has a negative pressure device installed on its upper surface, and a drainage tube is inserted into the surface of the negative pressure device.

[0010] A protective surface layer is disposed at the bottom of the patch portion, a first sealing strip is installed at the bottom of the patch portion, and a second sealing strip is installed on the surface of the protective surface layer;

[0011] Rubber limiting strips are provided on both sides of the upper surface of the patch, and medical gauze is wrapped between the rubber limiting strips.

[0012] Preferably, both the first and second sealing strips have a U-shaped design. The second sealing strip is installed on the outer periphery of the protective surface layer. The U-shaped design allows the first and second sealing strips to seal the part of the patch that comes into contact with the skin, thereby preventing external contamination.

[0013] Preferably, an adhesive layer is installed at the bottom of the first sealing strip, and a first release paper is adhered to the bottom of the adhesive layer. The first release paper is removed so that the first sealing strip can be adhered to the surface of the skin through the adhesive layer.

[0014] Preferably, the bottom of the patch portion has a groove, which is adapted to the position of the negative pressure device. The negative pressure device can extract the liquid from the wound through the groove, thereby expelling the liquid or gas from the wound and promoting wound healing.

[0015] Preferably, a second release paper is adhered to the bottom of the second sealing strip. The second release paper covers the bottom of the patch portion. Removing the second release paper exposes the part of the second sealing strip that is in contact with the skin, allowing the second sealing strip to make close contact with the skin.

[0016] Beneficial effects

[0017] Compared with the prior art, this utility model provides a wound-aiding healing device, which has the following features:

[0018] Beneficial effects:

[0019] This wound healing aid device uses a first sealing strip to seal the edges of the patch, preventing outside air from entering and thus avoiding contamination. Medical gauze is then used to bind the patch surface, compressing it and causing the second sealing strip to press against the skin surface. This compression seals the wound, and the protective layer covers the wound, promoting healing. Simultaneously, a negative pressure device removes excess fluid, preventing it from compromising the sealing stability of the healing aid device and improving the wound healing effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution, a wound-aiding healing device. Please refer to [link / reference]. Figure 1 Including patch section 1, please refer to Figure 2 A negative pressure device 2 is installed on the upper surface of the patch part 1, and a drainage tube 7 is inserted into the surface of the negative pressure device 2.

[0028] The protective surface layer 3 is disposed at the bottom of the patch portion 1, and the bottom of the patch portion 1 is fitted with a first sealing strip 4. Please refer to [link / reference]. Figure 5 A second sealing strip 10 is installed on the surface of the protective layer 3;

[0029] Please see Figure 3 Rubber limiting strips 5 are provided on both sides of the upper surface of the patch part 1, and medical gauze 6 is wrapped between the rubber limiting strips 5.

[0030] The first sealing strip 4 can seal the edge of the patch 1, preventing outside air from entering the patch 1 and thus avoiding external contamination. The medical gauze 6 is bound to the surface of the patch 1, which can compress the patch 1 and thus push the second sealing strip 10 against the skin surface. The compression method seals the wound. The protective layer 3 covers the wound and promotes wound healing. At the same time, the negative pressure device 2 can extract excess body fluid, preventing excessive body fluid from reducing the sealing stability of the auxiliary healing device, thereby improving the wound healing effect.

[0031] Please see Figure 4 and Figure 5Both the first sealing strip 4 and the second sealing strip 10 have a U-shaped design. The second sealing strip 10 is installed on the outer periphery of the protective surface layer 3. The U-shaped design allows the first sealing strip 4 and the second sealing strip 10 to seal the part of the patch 1 that comes into contact with the skin, thereby preventing external contamination.

[0032] Please see Figure 4 An adhesive layer 8 is installed at the bottom of the first sealing strip 4, and a first release paper 9 is adhered to the bottom of the adhesive layer 8. The first release paper 9 is removed so that the first sealing strip 4 can be adhered to the surface of the skin through the adhesive layer 8.

[0033] Please see Figure 2 The bottom of the patch part 1 is provided with a groove, and the groove of the patch part 1 is adapted to the position of the negative pressure device 2. The negative pressure device 2 can extract the liquid from the wound through the groove, and can discharge the liquid or gas in the wound to promote wound healing.

[0034] Please see Figure 5 The bottom of the second sealing strip 10 is adhered with a second release paper 11, which covers the bottom of the patch part 1. Removing the second release paper 11 exposes the bottom part of the second sealing strip 10, allowing the second sealing strip 10 to be in close contact with the skin.

[0035] The working process of this device is as follows: First, the first release paper 9 is removed, allowing the first sealing strip 4 to adhere to the skin surface through the adhesive layer 8. Then, the second release paper 11 is removed, exposing the bottom contact portion of the second sealing strip 10, allowing the second sealing strip 10 to make close contact with the skin. The first sealing strip 4 then seals the edge of the patch 1, preventing external air from entering the patch 1 and thus avoiding external contamination. Finally, medical gauze 6 is bound to the surface of the patch 1, squeezing the patch 1 and causing the second sealing strip 10 to be squeezed towards the skin surface. This squeezing method seals the wound. The protective layer 3 covers the wound and promotes healing. Simultaneously, the negative pressure device 2 extracts excess body fluid, preventing excessive body fluid from reducing the sealing stability of the auxiliary healing device, thereby improving the wound healing effect.
