AI Technical Summary
Existing polymer elastic bandages can easily cause tourniquet effects when the wound swells after surgery, affecting blood supply, especially in the distal extremities, which may lead to necrosis.
Multiple elastic foam sheets are placed on both sides of the polymer elastic bandage to reduce pressure on the wound and reduce the impact on blood supply through the cushioning area of the foam material.
When a wound swells, the elastic foam pads reduce the pressure of the bandage on the wound, minimize adverse effects on blood supply, and prevent the tourniquet effect.

Abstract
Description
Technical Field
[0001] This utility model relates to a polymer elastic bandage that prevents blood flow obstruction. Background Technology
[0002] Currently, postoperative wounds require hemostatic gauze and bandages. High-polymer elastic bandages are commonly used. When bandaging after surgery, the bandage is usually applied tightly. However, the wound will swell over time. If the bandage is initially applied too tightly, and the swelling becomes severe, it can create a tourniquet effect, severely affecting blood supply. This is especially true after surgery on the limbs, where insufficient blood supply to the distal parts of the hands and feet can even lead to necrosis. Therefore, there is an urgent need to develop bandages that can prevent the tourniquet effect. Summary of the Invention
[0003] This invention addresses the aforementioned problems of existing polymer elastic bandages by providing a polymer blood-blocking elastic bandage. The invention comprises a polymer elastic bandage, characterized by multiple elastic sheets disposed on the front and back sides. The elastic sheets are square or circular. The elastic sheets are made of foam material, specifically polyurethane foam. The advantages of this invention are: after the bandaged wound swells, the foam material covering the polymer elastic bandage creates a buffer zone between the bandage and the wound skin, and the spacing between the foam materials further reduces pressure on the skin and minimizes the impact on blood supply. Attached Figure Description
[0004] Figure 1 This is a side view of the structure of this utility model.
[0005] Figure 2 This is a front view of the structure of this utility model. Detailed Implementation
[0006] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.
[0007] The figure shows a polymer elastic bandage for preventing blood flow obstruction, comprising a polymer elastic bandage 1, characterized in that multiple elastic sheets 2 are provided on the front side of the polymer elastic bandage. Multiple elastic sheets 3 are provided on the back side of the polymer elastic bandage. The elastic sheets are square or circular. The elastic sheets are made of foam material, specifically polyurethane foam.
[0008] In actual production, elastic sheets of different thicknesses can be set according to different wound shapes, and elastic sheets of different hardness can also be produced. At the same time, elastic sheets of different sizes of square or round shapes can be produced as needed, and other geometric shapes can also be produced as required. The spacing 3 of the elastic sheets can be set according to different needs.
[0009] When a patient uses this invention to bandage a wound after surgery, it may initially fit tightly against the wound, exerting pressure to prevent bleeding. As the wound swells over time, the elastic polymer bandage, due to its elasticity, will expand with the swelling, increasing the pressure on the wound. However, the presence of foam elastic sheets within the bandage reduces this pressure, and the gaps between the foam elastic sheets further reduce the pressure on the wound, significantly minimizing any adverse effects on blood supply.
