Abstract

The invention relates to the technical field of biomedical materials, and discloses a medical multifunctional hemostatic dressing and a preparation method thereof. The medical multifunctional hemostatic dressing is sequentially composed of a functional bottom layer, a hydrophilic layer and a protective layer from the side close to the skin; the functional bottom layer is a non-woven fabric loaded with porous slow-release particles; the hydrophilic layer is loaded with amino-modified pumice A porous sponge; the protective layer is a thermoplastic polyurethane film. In addition to the strong liquid absorption and liquid locking ability of the dressing of the present invention, and the ability to activate the coagulation system in a short period of time for rapid hemostasis, the dressing also provides a slightly moist environment for wound healing and can promote wound healing, and The dressing does not adhere to the new granulation tissue, reducing the secondary pain caused by dressing changes.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to a medical multifunctional hemostatic dressing and a preparation method thereof. Background technique [0002] As the largest organ of the human body, the skin plays a role in maintaining the balance and stability of the human environment. However, daily life, surgery, etc. will cause skin damage and blood vessel rupture, which in turn will cause a series of effects on the body. Therefore, suitable materials are needed for hemostasis and repair of wounds. [0003] Traditional treatment methods mainly use hemostatic drugs and hemostatic dressings. Although hemostatic drugs have hemostatic effect, they are not easy to store, consume a large amount, easily cause allergies, easily form thrombus, have poor air permeability, and the wound is prone to redness and pus. Hemostatic dressings have become the focus of current research because of their advantages such as being m...
