Description

Technical Field

[0001] The present invention relates to the technical field of intelligent dressings, and in particular to an intelligent dressing for treating chronic wounds. Background Art

[0002] Wound healing is a complex process that is affected by many factors throughout the healing process. Systemic factors include age, nutritional status, functional status of the blood circulation system, infection, diabetes, obesity, etc. The final manifestation of the influence of these systemic factors is the local factors of the wound, such as wound temperature, humidity, pH, bacterial infection, etc. When the parameters of these local factors are within an appropriate range, the wound will heal well. The healing process of chronic wounds is particularly complex. The etiology of chronic wounds is complex. Through complex connections, wound cell damage, decreased growth factor activity, increased degradation of extracellular matrix, etc., will interfere with the normal wound healing process and even cause the wound to prolong. Chronic wounds are common in various clinical departments. Their etiology is complex and the course of the disease is long and prolonged. It has become a major problem in the 21st century. It not only has a significant negative impact on the patient's quality of life, but also creates a social medical burden with its huge dressing change costs. At the same time, infection can make the wound more difficult to heal, and difficult-to-heal wounds can be complicated by infection. So far, the way we judge whether the wound has healed is to remove the dressing and observe directly. If the wound surface has not healed at this time, it is very likely to cause infection on the wound surface, and eventually leave an indelible scar. This method not only causes pain to the patient, but also interferes with the normal healing of the wound surface and slows down the healing speed.

[0003] When the existing moist non-stick gauze is used on patients, it is difficult to continuously add therapeutic solutions to the therapeutic gauze body, which requires the gauze to be removed to add therapeutic solutions to the therapeutic gauze body. In addition, it is difficult to fix the therapeutic gauze body during use, which causes the therapeutic gauze body to fall off during use. Based on this, the present invention designs an intelligent dressing for chronic wound treatment to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent dressing for treating chronic wounds to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A smart dressing for treating chronic wounds comprises a fixing pad, a therapeutic gauze body, a liquid seepage mechanism and a fixing mechanism, wherein the liquid seepage mechanism comprises a retention needle hole, the top of the fixing pad is provided with a retention needle hole, a plurality of tubular holes are provided inside the fixing pad, the tubular holes are in a series state, and a plurality of through grooves are provided at the bottom of the tubular holes; therapeutic liquid can be added to the therapeutic gauze body by using the retention needle hole, the tubular hole and the through grooves in coordination.

[0007] The fixing mechanism includes a fixing bandage, fixing bandages are installed on both sides of the outside of the fixing pad, first adhesive tapes are installed on both sides of the outside of the fixing pad, and second adhesive tapes are installed on both sides of the outside of the fixing pad. The fixing pad can be fixed by using the fixing bandage, the first adhesive tape, and the second adhesive tape in combination.

[0008] Preferably, Velcro is installed on the outside of the fixing bandage, and the two fixing bandages are fixed by the Velcro.

[0009] Preferably, the material of the therapeutic gauze body is a moist non-stick gauze. The therapeutic gauze body has low viscosity, does not damage granulation tissue and new epidermis, and when removed, the dressing is removed painlessly. The therapeutic gauze body is a grid design, which is convenient for cutting and the flow of therapeutic liquid into the wound.

[0010] Preferably, the fixing pad is made of silicone material, which can better fit the patient's surface.

[0011] Preferably, the indwelling needle hole, the tubular hole and the through groove are in a sealed state, and liquid can only flow through the syringe during injection, thereby preventing bacteria on the outer surface of the therapeutic gauze body from entering the inside of the tubular hole through the through groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention can realize the continuous addition of therapeutic liquid to the therapeutic gauze body through the infiltration mechanism. The infiltration mechanism includes a retention needle hole, a tubular hole, and a through groove. When the therapeutic liquid needs to be supplemented to the therapeutic gauze body, the medical staff loads the injection liquid into the syringe. At this time, the injection tube head is inserted into the interior of the retention needle hole, and the injection tube is pushed. The injection liquid inside the injection tube enters the interior of the tubular hole. The injection liquid entering the tubular hole flows into the surface of the therapeutic gauze body through the through groove, so as to supplement the therapeutic liquid to the therapeutic gauze body.

[0014] 2. The present invention can fix the therapeutic gauze body through a fixing mechanism, and the fixing mechanism includes a fixing bandage, a first adhesive tape, and a second adhesive tape. When the therapeutic gauze body is used to treat a wound, the therapeutic gauze body needs to be fixed. At this time, the fixing bandage is pulled to fold the two fixing bandages, and the two fixing bandages are fixed by Velcro. After the fixing bandage is fixed, the fixing bandage can be fixed for a second time by using the first adhesive tape and the second adhesive tape in combination, so as to avoid the fixing bandage from falling off when the patient is walking, which would cause the therapeutic gauze body to fall off.

[0015] 3. When using the therapeutic gauze body to treat chronic wounds of patients, the therapeutic gauze body needs to be replaced regularly to avoid bacterial growth. When replacing the therapeutic gauze body, the inside of the indwelling needle hole, tubular hole, and through-groove needs to be disinfected. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The fixing mechanism includes a fixing bandage 401, the fixing bandage 401 is installed on both sides of the outside of the fixing pad 1, the first adhesive tape 402 is installed on both sides of the outside of the fixing pad 1, and the second adhesive tape 403 is installed on both sides of the outside of the fixing pad 1. The fixing pad 1 can be fixed by using the fixing bandage 401, the first adhesive tape 402, and the second adhesive tape 403 in combination;

[0029] The exterior of the fixing bandage 401 is provided with a Velcro 404. The two fixing bandages 401 are fixed by the Velcro 404. The material of the treatment gauze body 2 is a moist non-stick gauze. The treatment gauze body 2 has low viscosity and does not damage granulation tissue and new epidermis. When the dressing is removed, it is painless. The treatment gauze body 2 is a grid design, which is convenient for cutting and for the treatment liquid to flow into the wound.

[0030] The material of the fixing pad 1 is silicone material. It can better fit the patient's surface, and the indwelling needle hole 301, the tubular hole 302, and the through groove 303 are in a sealed state, and liquid can only flow through the syringe during injection. It is prevented that bacteria on the outer surface of the treatment gauze body 2 enter the inside of the tubular hole 302 through the through groove 303.

[0031] When the treatment gauze body 2 is needed to treat the patient, the treatment gauze body 2 is cut into the shape required by the patient, the patient's wound is cleaned and disinfected, and after cleaning and disinfection, the treatment gauze body 2 is placed on the patient's wound, and then the treatment gauze body 2 is smeared with treatment medicine. The treatment gauze body 2 has low viscosity and does not damage granulation tissue and new epidermis. When it is taken out, the dressing is taken out painlessly. The treatment gauze body 2 is designed as a grid, which is convenient for cutting and the treatment liquid to flow into the wound.
