Description

Technical Field

[0001] The present invention relates to the technical field of burn rehabilitation equipment, and in particular to a convenient dressing-changing treatment device for repairing burn wounds. Background Art

[0002] In the field of burn treatment, wound care on the hands, especially the fingers, has always been a key and difficult point in clinical practice. Traditional dressing changes have significant limitations: when medical staff change dressings for patients, due to the adhesion between wound exudate and gauze, a lot of time and energy are required to separate the dressings layer by layer. This process may not only cause mechanical damage to the new tissue, but also cause severe pain due to stimulation of the nerve endings in the wound. For the special anatomical part of the finger, its large joint mobility, thin skin and less subcutaneous tissue make it difficult to effectively fix it with conventional bandages. Clinical data show that the incidence of dressing detachment in patients with finger burns who use traditional gauze bandages is as high as 68%, which not only increases the risk of wound infection, but also may delay the healing process.

[0003] Although some rigid braces in existing protective devices can provide static support, they lack dynamic adjustment function and cannot adapt to the physiological activity requirements of finger joints. Long-term wear can easily lead to joint stiffness, and it is impossible to take into account both wound observation and the convenience of dressing changes. Although elastic bandage products have certain flexibility, it is difficult to maintain stable pressure when the fingers are in a flexed position. Especially when sleeping at night, the patient's unconscious limb movements often cause the bandage to shift, resulting in fixation failure. Therefore, the present invention provides a convenient dressing change treatment device for burn wound repair to solve the above technical problems. Summary of the Invention

[0032] The bottom fixing assembly shell 1 includes a bottom shell A101 and a bottom shell B102, and the bottom shell A101 is rotatably connected to the bottom shell B102;

[0033] The top fixing assembly shell 3 includes a top shell A301 and a top shell B302, and the top shell A301 is rotatably connected to the top shell B302;

[0034] The bottom shell A101 is movably connected to the top shell A301 through the fixing assembly 6, and the bottom shell B102 is movably connected to the top shell B302 through the fixing assembly 6.

[0035] A Velcro surface A103 is fixedly provided on the surface of the bottom shell A101, and a Velcro adhesive tape A104 is fixedly provided on the surface of the bottom shell B102.

[0036] A Velcro surface B303 is fixedly provided on the surface of the top cover A301, and a Velcro tape B304 is fixedly provided on the surface of the top cover B302.

[0037] Reference Figure 2 The corrugated shell group 2 includes a corrugated bend tube A201 and a corrugated bend tube B202. The upper and lower ends of the corrugated bend tube A201 are fixedly connected to the top shell A301 and the bottom shell A101 respectively. The upper and lower ends of the corrugated bend tube B202 are fixedly connected to the top shell B302 and the bottom shell B102 respectively. When the corrugated bend tube A201 and the corrugated bend tube B202 cover each other, they can form a sealed corrugated tube structure together. It is worth noting that the corrugated shell group 2 can be a transparent silicone corrugated tube structure, which allows medical staff to directly observe the wound condition in the device without the need to frequently remove the device.

[0038] Reference Figure 4 The fixing assembly 6 includes a fixing rod A601, a fixing rod B602, a threaded nail 605, and a fixing nut 606. An adjustment slot A603 is provided in the fixing rod A601, and an adjustment slot B604 is provided in the fixing rod B602. The threaded nail 605 passes through the adjustment slot A603 and the adjustment slot B604 in sequence, and a fixing nut 606 is threadedly sleeved on the other end of the threaded nail 605. By rotating the threaded nail 605, the angle between the fixing rod A601 and the fixing rod B602 can be flexibly adjusted, thereby realizing the angle adjustment between the bottom fixed group shell 1 and the top fixed group shell 3.

[0039] Reference Figure 5 The limiting component 7 includes an insertion slot 701, and a limiting cotton pad 702 is detachably inserted in the insertion slot 701; it is worth noting that the folded shell 2 made of silicone material and the limiting cotton pad 702 (medical-grade polyurethane foam) provide a gentle contact interface to avoid compressive damage to the thin skin.

[0040] Reference Figure 6 The fitting bottom shell 5 includes a fitting pad A501 and a fitting pad B502. The fitting pad A501 is fixedly installed on the bottom surface of the bottom shell A101, and the fitting pad B502 is fixedly installed on the bottom surface of the bottom shell B102. A Velcro tape C503 is fixed on the surface of the fitting pad B502, and a Velcro surface C504 is fixed on the surface of the fitting pad A501.

[0041] In the present invention, when in use, medical staff clean the wound surface with normal saline to remove necrotic tissue and exudate; cover with a sterile dressing (such as silver-containing antibacterial gauze), the dressing area should exceed the edge of the wound surface by 1-2 cm, and the outer layer of gauze should be gently pressed to absorb the exudate; the thickness of the limiting cotton pad 702 is selected according to the circumference of the patient's finger (such as 3 mm for the middle finger of a child and 5 mm for the middle finger of an adult), and the cotton pad is inserted into the insertion groove 701 on the inner wall of the bottom / top shell to ensure a tight fit without displacement;

[0042] The medical staff holds the bottom shell A101 and the bottom shell B102 with both hands respectively, and slowly inserts the finger (such as the middle finger) from the opening of the bottom shell A101 and the bottom shell B102, so that the top shell A301 and the top shell B302 cover the fingertips to the proximal phalanx area; align the Velcro surface A103 and the Velcro tape A104, and gently press to close, ensuring that the bottom fixing group shell 1 fits the base of the finger without causing a sense of pressure, align the Velcro surface B303 and the Velcro tape B, and after closing, check whether the top shell is stably wrapping the distal end of the finger; finally, align the Velcro tape C503 and the Velcro surface C504 on the surface of the fitting pad A501 and the fitting pad B502 and press and bond them to ensure that the fitting bottom group shell 5 is tightly attached to the skin on the side of the finger base without curling or gaps.

[0043] Angle adjustment and locking

[0044] During dynamic angle adaptation: loosen the fixing nut 606, and slowly move the finger according to the natural flexion angle of the patient's finger (such as 45°), driving the fixing rod A601 and the fixing rod B602 to slide to the appropriate position in the adjustment slot A603 and the adjustment slot B604. This structure does not affect the movement of the finger.

[0045] When locking the angle: tighten the fixing nut 606 so that the screw 605 presses against the inner wall of the adjustment slot to achieve angle locking. Make sure there is no looseness. Ask the patient to actively flex and extend the fingers 2-3 times to observe whether the device bends synchronously with the joint movement.

[0046] Daily maintenance and dressing change operations

[0047] Daily functional training: Loosen the fixing nut three times a day and perform finger flexion and extension training for 5 minutes each time. During each training, the patient slowly straightens the finger to the maximum angle (about 0°), holds for 5 seconds, flexes the finger to the maximum angle allowed by the device (about 90°), holds for 5 seconds, and repeats 10-15 times. During the process, observe whether the wound dressing is displaced.

[0048] Convenient dressing change process

[0049] Loosen the Velcro tape B304 of the top cover A301 and the top cover B302, as well as the Velcro tape A104 of the bottom cover A101 and the bottom cover B102, fold the top cover A301 and the bottom cover A101 upwards to expose the wound, remove the outer gauze with tweezers, retain the inner antibacterial dressing (if it is not soaked, it does not need to be replaced), spray the wound with disinfectant (such as povidone iodine), cover with a new dressing, and then reposition the top cover A301 and the bottom cover A101, and reclose the Velcro tape A104 and the Velcro tape B304.

[0050] It is worth noting that you can wear a waterproof film covering device when taking a bath to avoid long-term immersion of silicone parts; it is recommended to fix your fingers in a functional position (semi-flexed 45°) when sleeping at night to reduce displacement caused by unconscious activities.

[0051] Through the above-mentioned standardized operating procedures, the device can significantly improve the treatment efficiency of burned finger wounds, while reducing patient pain and the workload of medical staff; clinical practice has shown that the standardized use of this device can shorten the dressing change time to 3 minutes / time (the traditional method takes 15 minutes) and reduce the incidence of joint stiffness by 72%; clinical tests when using this device have shown that the dressing shedding rate dropped from 68% to 8%.

[0052] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the embodiments of the present application is limited only by the appended claims.

[0053] The above-described embodiments merely represent several implementation methods of the embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the embodiments of the present application, and these modifications and improvements fall within the scope of protection of the embodiments of the present application.
