Multi-layer calcium-based zeolite fiber hemostatic clothing and manufacturing method thereof

Abstract

The invention provides an outdoor activity emergency hemostatic garment which is efficient and easy to operate. The multi-layer calcium-based zeolite fiber hemostatic garment comprises a three-layer structure which sequentially comprises an outermost layer, a middle layer and an innermost layer, wherein the outermost layer is a calcium-based zeolite fiber layer, the middle layer is a hydrophobic fiber layer, and the innermost layer is a hydrophilic fiber layer; and the calcium-based zeolite fiber layer comprises calcium-based zeolite and fibers, and the calcium-based zeolite is independently dispersed on the surfaces of the fibers. According to the hemostatic garment, the operability during use is ensured, and the problem of loss of calcium ions during use is solved, so that the high-efficiency hemostatic property is achieved.

Description

technical field [0001] The invention belongs to the technical field of biomedical materials, and in particular relates to an efficient and easy-to-operate emergency hemostatic garment and a manufacturing method thereof. Background technique [0002] Most of the emergency hemostatic materials currently on the market are tourniquets. The tourniquet is generally made of natural rubber and is wide and flat. It is used for hemostasis in the first aid of massive bleeding in the limbs. It achieves the purpose of hemostasis by blocking the blood flow by compressing the blood vessels. Although it is widely used, there are still many defects: (1) the use position of the tourniquet is limited, and there are only two positions where the tourniquet can be used: the upper part of the forearm and the thigh. The binding position should be above the wound (near the heart), and as close to the wound as possible, preferably the upper 1 / 3 of the upper arm and the upper middle of the thigh. Th...

The human body will definitely secrete sweat during outdoor activities. The main components of sweat are water and sodium chloride. When using the hemostatic clothing prepared by the hemostatic compound in this patent, the zeolite and sodium chloride will directly contact, and ion separation will occur. exchange, which reduces the content of calcium ions in zeolite, resulting in a decrease in coagulation performance

The hemostatic compound prepared by this patent cannot meet the application of the actual scene of outdoor activities
