Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical treatment technology, and in particular to an adjustable anatomical pressure therapeutic dressing. Background Technology
[0002] Chronic lower extremity venous disease is prone to occur due to upright walking, weight-bearing walking, or prolonged standing, leading to vascular congestion in the lower limbs. In later stages, it often results in chronic ulcers, causing patients long-term discomfort and physical and psychological suffering. With the continuous development of medical technology, clinical drugs, and surgical treatments, it has been proven that pressure therapy can promote centripetal blood flow in the veins, prevent backflow and stagnation, thereby reducing symptoms such as lower limb swelling and pain, effectively protecting lower extremity veins, and slowing disease progression. Due to its effectiveness, safety, and cost-effectiveness, it can be applied to all stages of the treatment of chronic lower extremity venous disease. Current pressure therapy simply involves wrapping the foot and lower leg with a standard square cotton pad, then securing it with an elastic bandage. Because the foot and lower leg form a 90-degree angle, the square cotton pad often creates overlapping wrinkles, resulting in poor comfort. The pad at the ankle doesn't conform evenly to the limb. After being secured with the elastic bandage, the tapered structure of the foot and lower leg (wider at the top and thinner at the bottom) causes the bandage to shift laterally towards the narrower end during lower limb movement. This leads to the bandage loosening and decompression, failing to achieve the intended pressure therapy effect. Furthermore, the cotton pad is prone to tilting during wrapping and securing, making the process cumbersome and difficult for medical staff. Utility Model Content
[0003] The purpose of this invention is to provide an adjustable anatomical pressure therapy dressing that provides a flat, snug fit to the foot, with controllable pressure, is not prone to displacement, has good pressure therapy effect, is easy to operate, and is less likely to cause infection.
[0004] To achieve the above requirements, the technical solution of this utility model is characterized by comprising a cotton pad for wrapping the lower limb from the middle of the instep through the ankle to the middle of the calf, and a self-adhesive elastic bandage for wrapping the lower limb with the cotton pad and then securing it tightly around the outside of the cotton pad. The front and back of the cotton pad are made of medical degreased gauze with medical degreased cotton sandwiched in the middle. Velcro fasteners that can be glued to each other are fixed on both sides of the front and back of the cotton pad. Triangular notches are made on the left and right sides of the front end of the cotton pad. The depth and angle of the notches are such that the cotton pad can be sewn together at the ankle after the Velcro fasteners on the left and right sides of the cotton pad overlap.
[0005] The included angle of the notch in the triangle is between 85 and 95 degrees.
[0006] The lower half of the cotton pad is rectangular, and the upper half is a trapezoid with a larger top and a smaller bottom, wherein the width of the lower side of the upper half of the cotton pad is the same as the width of the upper side of the lower half of the cotton pad.
[0007] Two self-adhesive elastic bandages are sewn and fixed to the lower half and the lower side of the upper half of the cotton pad, respectively.
[0008] The self-adhesive elastic bandage has a size of 10×450 cm.
[0009] An adjustable anatomical pressure therapy dressing designed according to the above scheme is made by wrapping a cotton pad with a self-adhesive elastic bandage and tightening it. The cotton pad is designed with triangular notches and Velcro on both sides, so that the cotton pad fits evenly with the patient's lower limb and is fixed with Velcro. The cotton pad will not shift when the self-adhesive elastic bandage is wrapped and tightened, which is convenient for the bandage to be wrapped and tightened and facilitates the operation of medical staff. The bandage used is a self-adhesive elastic bandage. During wrapping, the bandages overlap and interlock in the width direction, applying pressure to the cotton pad and bonding the layers together. This wrapping structure ensures the layers of the self-adhesive elastic bandage are firmly bonded, preventing loosening and shifting. This fully meets the requirements for pressure therapy on the legs and feet, is convenient to use, and comfortable for the patient. The cotton pad has an open structure, allowing for the selection of different sizes based on the patient's limb thickness and size. The self-adhesive elastic bandage can be wrapped with adjustable tension according to the condition, achieving adjustable pressure. The self-adhesive elastic bandage is an existing product. This pressure therapy dressing, including the upper and lower cotton pads and the self-adhesive elastic bandage, is integrated into a single unit. After sterilization, it is packaged in a sealed dressing bag. When using it, simply open the dressing bag to wrap the bandage; no extra steps are required, making it very convenient and preventing medical personnel from touching materials outside the dressing bag, thus preventing infection.

[0017] The present invention will be further described below through embodiments.
[0018] It includes a cotton pad for wrapping around the instep, down the ankle, and down the calf, on both sides. Figure 1 , Figure 2 As shown, and the self-adhesive elastic bandage 2 used to wrap around and tighten the cotton pad 1 after the lower limbs are wrapped in the cotton pad 1. Figure 3 As shown. From Figure 1 and Figure 2 As can be seen, the total length of the cotton pad 1 is L. The lower half (L / 2) is rectangular, and the upper half (L / 2) is a trapezoid, wider at the top and narrower at the bottom. The width of the lower side of the upper half of the cotton pad 1 is the same as the width of the upper side (H) of the lower half. The front and back of the cotton pad 1 are made of medical degreased gauze 3, with medical degreased cotton 4 sandwiched in between. Velcro 5, which can be glued together, is fixed to the left and right sides of the front and back of the cotton pad 1. Triangular notches 6 are made on the left and right sides of the front end of the cotton pad 1, with the included angle A of 85 to 95 degrees. The depth of the notches 6 and the included angle A are such that the cotton pad 1 can be seamlessly joined at the ankle after the Velcro 5 on the left and right sides overlap. The self-adhesive elastic bandage 2 has dimensions of 10×450 cm (10 cm wide, 450 cm long) and is an existing product. Two self-adhesive elastic bandages 2 are sewn onto the lower half and upper half of the cotton pad 1, respectively, at the lower edge of the sides. Figure 4 As shown.
[0019] When using, place the patient's heel at the midpoint of the line connecting the two triangular notches. The left and right sides of the cotton pad 1 are then joined together to wrap around the middle of the patient's instep, extending from the ankle to the middle of the calf. The left and right sides are then secured using Velcro 5. Figure 5 As shown, wrap the self-adhesive elastic bandage 2 around the cotton pad 1 from bottom to top, overlapping each other in the width direction of the bandage as shown. Figure 6As shown. During use, the self-adhesive elastic bandage 2 is stretched while being wrapped, applying pressure to the leg and foot area to a strength of 34–46 mmHg (45–61 hPa), meeting the requirements for pressure therapy. The self-adhesive elastic bandage 2 is typically composed of elastic fabric and a self-adhesive layer. The elastic fabric provides the bandage's elasticity, allowing it to adapt to different limb shapes and movements, as well as applying pressure to the wrapped area; the unique feature of the self-adhesive layer is that it allows the bandages to adhere and fix together after wrapping. During the wrapping process, the self-adhesive elastic bandage 2 applies pressure to the cotton pad 1 and also bonds the upper and lower layers of the self-adhesive elastic bandage 2 together. This structure ensures that the layers of the self-adhesive elastic bandage 2 are bonded together seamlessly, preventing loosening and shifting, fully meeting the requirements for pressure therapy on the leg and foot area. It is convenient to use and comfortable for the patient. The cotton pad 1 it wraps around has an open structure. The cotton pads 1 can be made in various proportional sizes according to the size of the individual. When wrapping, different sizes of cotton pads 1 can be selected according to the thickness and size of the patient's limbs. When wrapping, the self-adhesive elastic bandage 2 can provide reasonable tension according to the needs of the condition to achieve adjustable pressure. The self-adhesive elastic bandage 2 is an existing product.
