Technical Field
[0001] The utility model relates to the field of medical technology, and more particularly to a novel dressing for burn wound repair. Background Art
[0002] The existing methods for treating burn wounds mainly involve covering the wound with sterilized gauze to protect the wound surface from external contamination and keep the wound surface moist, which is beneficial to cell growth and granulation tissue hyperplasia, and promotes healing. However, this treatment method has the following disadvantages: due to the failure to replace the gauze in a timely manner, the chance of wound surface infection increases; the gauze is prone to drying out, affecting the wound healing speed. The exudate soaks into other items such as clothes, causing secondary infection or injury. How to provide a novel dressing for burn wound repair has become a research direction.

The audible and visual alarm is provided with a first humidity indicator corresponding to the first humidity sensor, a second humidity indicator corresponding to the second humidity sensor, and an alarm horn. The edge of the hydrophobic layer is provided with a pasting part for conveniently fixing on the wound surface.
[0005] The novel dressing for burn wound repair provided by the utility model can monitor the humidity of the wound surface environment in real time by setting the first humidity sensor and the second humidity sensor, and send an alarm to remind medical staff to replace the dressing when the humidity is too high; in addition, the novel dressing also has a waterproof function to prevent the exudate from soaking into other items such as clothes, thus avoiding secondary injury caused by improper care of the patient's family members.
[0006] Preferably, the antibacterial layer is made of a nanofiber material loaded with silver ions.
[0007] Preferably, the breathable bottom layer has a porous structure.
[0008] Preferably, the pasting part is a reusable pressure-sensitive tape.
[0009] Preferably, both the first absorbent gauze layer and the second absorbent gauze layer are made of absorbent cotton.
[0010] Preferably, the hydrophobic layer is a polytetrafluoroethylene membrane.

[0014] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.
[0015] In the description of the embodiments of the present utility model, if a certain feature is referred to as "arranged", "fixed", "connected", "installed" on another feature, it can be directly arranged, fixed, connected, installed on another feature, or indirectly arranged, fixed, connected, installed on another feature. In the description of the embodiments of the present utility model, if "several" is involved, its meaning is more than one, if "a plurality" is involved, its meaning is more than two, if "greater than", "less than", "exceeding" are involved, it should be understood as not including the present number, if "above", "below", "within" are involved, it should be understood as including the present number. If "first" and "second" are involved, it should be understood as being used to distinguish technical features and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0016] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.
[0017] The preferred embodiments of the present utility model are shown in the accompanying drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.
[0018] Embodiment
[0019] The technical solutions of the present utility model will be further described in detail below in conjunction with the accompanying drawings, but they should not be construed as limiting the scope of the patent of the present utility model.
[0020] As Figure 1 shown, an embodiment of the present utility model provides a novel dressing for burn wound repair, which includes a hydrophobic layer 10, a first absorbent gauze layer 20, an antibacterial layer 30, a second absorbent gauze layer 40, and a breathable bottom layer 50 from bottom to top. A first humidity sensor S1 is arranged between the first absorbent gauze layer 20 and the antibacterial layer 30, and a second humidity sensor S2 is arranged between the antibacterial layer 30 and the second absorbent gauze layer 40. Both the first humidity sensor S1 and the second humidity sensor S2 are electrically connected to an audible and visual alarm 60 through a wire L. The audible and visual alarm 60 is provided with a first humidity indicator D1 corresponding to the first humidity sensor S1, a second humidity indicator D2 corresponding to the second humidity sensor S2, and an alarm horn B. A paste portion V for conveniently fixing on the wound surface is provided at the edge of the hydrophobic layer 10.
[0021] The working principle of the above novel dressing is as follows: When the novel dressing is used for dressing, if the humidity around the wound surface is high, the first humidity sensor S1 and / or the second humidity sensor S2 will sense the wet signal and transmit it to the audible and visual alarm 60. At this time, the audible and visual alarm 60 will emit a sound to prompt the medical staff to replace the dressing in time; at the same time, the staff can also observe the lit state of the first humidity indicator D1 and / or the second humidity indicator D2 to judge whether the current humidity is too high.
[0022] As another alternative embodiment, the antibacterial layer 30 is made of a nanofiber material loaded with silver ions. The bactericidal effect of silver ions can effectively inhibit the reproduction of bacteria and reduce the chance of wound surface infection.
[0023] In addition, the breathable bottom layer 50 has a porous structure to facilitate air circulation and ensure an adequate supply of fresh oxygen.
[0024] Furthermore, the paste portion V is a reusable pressure-sensitive tape, which is convenient for doctors to disassemble and replace the dressing multiple times.
[0025] Both the first absorbent gauze layer 20 and the second absorbent gauze layer 40 are made of absorbent cotton because absorbent cotton has strong adsorption ability and is not easy to breed bacteria.
[0026] Finally, the hydrophobic layer 10 is a polytetrafluoroethylene film, i.e., a Teflon film, which is a chemically inert high molecular compound and has the characteristics of high temperature resistance, corrosion resistance, and non-wetting by water, etc.
[0027] In summary, for the novel dressing for burn wound repair provided by the present utility model, by setting the first humidity sensor and the second humidity sensor, the humidity condition of the wound surrounding environment can be monitored in real time, and an alarm is issued to remind medical staff to change the dressing when the humidity is too high; in addition, this novel dressing also has a waterproof function to prevent exudate from soaking into other items such as clothes, thereby avoiding secondary injuries caused by excessive care by the patient's family members.
[0028] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. The above-described embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
