Wound protection appliance

Abstract

In order to prevent wound ulcers, in particular against neurological and neuroischemic diabetic foot ulcers. The invention provides a wound protection appliance. The surface of the appliance is in a wavy concave-convex shape. And an adsorption layer capable of absorbing wound seepage is arranged below the wavy concave-convex surface layer. The elasticity of the material of the wave-shaped concave-convex surface layer is higher than that of the seepage adsorption layer, and air holes need to be densely distributed in the material of the wound protection device. The wound protection appliance can effectively keep the wound and surrounding skin dry and comfortable, reduce bacterium breeding and promote wound healing.

Description

(1) Technical Field

[0001] The present invention mainly aims at methods for wound treatment in clinical practice. The present invention also includes methods of decompression therapy, particularly for neuropathic and neuroischemic diabetic foot ulcers. (2) Background Art

[0002] The Guidelines for the Prevention and Treatment of Diabetic Foot in China (2019 Edition) points out that it is recommended that diabetic patients wear suitable shoes with foot protection functions, including sufficient length, width, and depth. The removal of calluses should be performed by medical staff trained in diabetic foot specialty. It is recommended to use decompression shoes for decompression therapy after callus trimming. Non-removable decompression devices and decompression shoes have obvious effects on the prevention and treatment of diabetic foot ulcers. Orthopedic decompressors designed and manufactured based on plantar pressure and foot shape can more effectively prevent and reduce the occurrence of foot ulcers in high-risk patients. It is recommended to select a suitable decompression device according to the actual situation of the patient to prevent foot ulcers. The decompression therapy for DFU started relatively late in China, with insufficient attention. The overall level of relevant production equipment, raw materials, manufacturing technology, and training of professional and technical personnel lags behind that of European and American countries, resulting in a considerable number of high-risk DFU and pressure ulcer patients not receiving effective prevention and treatment, which is also related to the high amputation rate. At present, a few domestic units, including the author's unit, have carried out the application and research of this technology in line with the domestic situation, achieving certain clinical efficacy and experience accumulation, which is worthy of further exploration and promotion.

[0003] The 2019 International Working Group on the Diabetic Foot Guidelines recommend: (1) For diabetic neuropathic plantar forefoot or midfoot ulcers, it is recommended to use a non-removable knee-high decompression brace as the first choice for decompression treatment. If there are contraindications or the patient is intolerant, the removable knee-high or removable ankle-high decompression braces are regarded as the second and third choices for decompression treatment respectively. Combining a well-fitting footwear with felt-like foam according to local conditions can be regarded as the fourth choice for decompression treatment. (2) For diabetic patients with neuropathic ulcers in the mid-forefoot, if accompanied by mild infection or mild ischemia, a non-removable knee-high device can be considered to promote ulcer healing; for diabetic patients with neuropathic ulcers in the mid-forefoot, if accompanied by mild infection and mild ischemia, or moderate infection or moderate ischemia, a removable knee-high device can be considered to promote ulcer healing; for diabetic patients with neuropathic ulcers in the mid-forefoot, if accompanied by moderate infection and moderate ischemia, or severe infection or severe ischemia, the infection and / or ischemia should be addressed first, and then a removable decompression device can be considered according to the patient's body function, activity status, and exercise level, etc. to promote ulcer healing. (3) For diabetic patients with neuropathic heel ulcers, a knee-high decompression device that can effectively reduce plantar pressure and is tolerable to the patient or other decompression intervention means can be considered to promote ulcer healing. (4) For diabetic patients with non-plantar ulcers, according to the different types and locations of the ulcers, a removable supra-ankle decompression device, orthopedic shoes, toe pads or toe orthotics are used to promote ulcer healing. (5) In addition, if non-surgical decompression fails, surgical decompression intervention is recommended to promote the healing of metatarsal head and toe ulcers. (III) Summary of the Invention

[0004] In order to prevent wound ulcers, the present invention proposes a wound protection device, the surface of which has a 1 wavy concave-convex shape. The wavy concave-convex shape can reduce the pressure-bearing area of the wound, and can prevent the surrounding blood circulation from being blocked, resulting in the aggravation of the wound condition, ensuring good blood supply to the wound, and thus promoting wound healing.

[0005] Exudate usually oozes from the wound, and it is necessary to absorb the exuded exudate in time to avoid the wound being macerated, which is beneficial to the recovery of the wound. Therefore, an 3 adsorption layer capable of absorbing wound exudate is provided under the 2 surface layer of the wavy concave-convex shape. The material of the surface layer of the wavy concave-convex shape is more elastic than that of the exudate adsorption layer, and the material of the wound protection device needs to be densely covered with 5 ventilation holes. The wound protection device can effectively keep the wound and the surrounding skin dry, reduce bacterial growth, and promote wound healing.

[0006] Such as Figure 1A wound protection device as shown has a hollow structure that allows the wound to be located in the hollow part of the wound protection device, and the contact surface of the wound protection device is around the wound. It has 6 metal wires inside, and by changing the shape of the metal wires, the shape of the hollow part can be fixed to correspond to any wound shape. (IV) Description of the Drawings
