Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical dressings, in particular to a diabetic foot ulcer wound dressing. Background Art
[0002] Diabetic foot is a common and serious complication of diabetes. Its ulcer wounds not only heal slowly but are also highly susceptible to infection, which has a serious impact on the patient's quality of life.
[0003] Conventional dressings fail to take into account the special physiological structure of the ankle joint and the characteristics of the patient's daily activities in their design, making it difficult to achieve effective fixation. When patients walk or perform daily activities, the dressings are prone to shifting or falling off, which not only reduces the protective effect on the wound, causing wound exposure and increasing the risk of infection, but also requires frequent dressing changes, which increases the financial burden on patients and brings many inconveniences to patients and caregivers.
[0004] To avoid the above situation, medical tape is usually wrapped around the outside of the dressing to fix it. If the tape is wrapped too loosely, the stability of the dressing cannot be guaranteed. If it is wrapped too tightly, it will hinder blood circulation in the ankle, causing local swelling and pain, affecting wound healing, and making it difficult to provide continuous and effective protection for the wound.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: a diabetic foot ulcer wound dressing patch, comprising a pair of shaping patches 1 that fit the ankle area and a connecting belt 2 for connecting the pair of shaping patches 1. The connecting belt 2 is used to connect the shaping patches 1 around the sole of the foot to prevent the dressing patch from sliding up and down or shifting during walking or daily activities. The outer layer of the plastic patch 1 is made of non-woven fabric and has a certain air permeability. The adhesive surface is provided with medical glue for attachment to the skin surface. It is worth mentioning that the adhesive surface of the plastic patch 1 is provided with an isolation layer (existing technology, not shown in the figure), which is generally made of silicone oil paper or plastic film. When the dressing patch is not in use, it covers the adhesive surface to protect the adhesiveness of the adhesive surface and prevent it from being contaminated or prematurely attached during storage and transportation. The edge of the shaping patch 1 is provided with multiple incisions, which make the edge of the plastic patch 1 easier to bend and deform, can better fit the ankle area, reduce the displacement or shedding of the plastic patch 1 caused by activities, and improve the comfort and stability of use. One of the shaping patches 1 is provided with elastic bands 4 on both sides, and the other shaping patch 1 is provided with an absorbent dressing 3 at the central position. The absorbent dressing 3 can be made of hydrogel or silver ion material, and adjustment buckles 5 are provided on both sides of the absorbent dressing 3. The adjustment buckles 5 are connected to the elastic bands 4 to adjust the tightness of the elastic bands 4. A pair of shaping patches 1 are attached to the inner and outer ankle joints around the sole of the foot through the connecting belt 2. The elastic bands 4 on both sides are connected around the ankles respectively, and can be properly stretched and adjusted according to the thickness of the patient's ankle to provide appropriate pressure, thereby further enhancing the fixing effect of the shaping patch 1, so that it can fit tightly at the ankle joint position and remain in the correct position even when the patient is moving, thereby continuously protecting and treating the wound.
[0024] See also Figure 3-Figure 6A clamping cavity for the elastic band 4 to pass through is provided in the adjusting buckle 5, and a plurality of equally spaced pressing teeth 7 are provided on the inner wall of one side of the clamping cavity. The cross-section of the pressing tooth 7 is a right triangle, and its hypotenuse is arranged on the side close to the elastic band 4, and the connection between the hypotenuse and the inner wall of the adjusting buckle 5 is chamfered. The advantage of such a setting is that a guide is provided for the elastic band 4 to pass through the adjusting buckle 5, and a spring sheet 8 is fixedly installed on the inner wall on the other side. A bending section is provided at one end of the spring sheet 8, and the bending section extends to contact with the pressing tooth 7. A slider 6 is slidably installed on the side close to the spring sheet 8 of the adjusting buckle 5, and the slider 6 contacts the spring sheet 8 so that the sliding slider 6 drives the spring sheet 8 to deform and release the constraint on the elastic band 4. The adjusting buckle 5 is provided with a trapezoidal opening at one end close to the slider 6. The advantage of such a setting is that it is convenient to push the slider 6 to slide in the adjusting buckle 5 through the trapezoidal opening position. The corner connections of the adjusting buckle 5 are all chamfered and smoothly transitioned. The rounded corners are not easy to cause tingling or pressure on the patient's skin, nor are they easy to hook the patient's clothes. The inner wall of the adjusting buckle 5 is provided with a slide groove 10 for accommodating the slider 6. A pair of extension parts 9 are integrally formed on one side of the slider 6. The end of the extension part 9 is an arc structure. The purpose of such a setting is to reduce the friction with the spring sheet 8. The end of the extension part 9 extends to contact the bent section of the spring sheet 8.
[0025] When using the shaping patch 1, first tear off the isolation layer set on the inner side of one side of the shaping patch 1, align the absorbent dressing 3 with the ulcer wound at the ankle joint, smooth the shaping patch 1 and stick it on the skin, then wrap the connecting belt 2 around the sole of the foot, and stick another shaping patch 1 to the ankle joint on the other side. Then wrap the elastic band 4 around the ankle joint and extend it into the adjustment buckle 5, push the slider 6 at the trapezoidal opening of the adjustment buckle 5, drive the extension part 9 to slide horizontally and compress the spring sheet 8 to deform until the bending section of the spring sheet 8 is away from the pressing tooth 7, and the elastic band 4 can pass through the adjustment buckle 5 between the pressing tooth 7 and the spring sheet 8. After adjusting the elastic band 4 to a suitable tightness, release the slider 6, and the spring sheet 8 releases its own elastic potential energy to drive the slider 6 to slide and reset, and the spring sheet 8 compresses the elastic band 4 and contacts the pressing tooth 7 to restrict the length of the elastic band 4. Because the elastic band 4 has a certain elasticity, when it is fixed around the ankle, it can exert a moderate pressure on the ankle. This pressure can promote the return of venous blood in the lower limbs, reduce edema in the ankle area, help improve the local blood circulation of diabetic foot patients, and create better conditions for wound healing. This wearable design conforms to the physiological curves of the human foot and ankle, does not hinder normal joint movement, and the patient can move the ankle freely, which improves the comfort and convenience of use.
