Embodiment 1

[0017] according to figure 1 , The hemostatic patch of the present invention includes 1-2 layers of polyester viscose non-woven fabric (2) and 1 layer of calcium alginate non-woven fabric (1), and the 2-3 layers of non-woven fabric are reinforced together by acupuncture reinforcement. The needle punching reinforcement method uses a micro-needling machine, and its main structure includes a needle board, a trawl board, and a screen board. To determine the fastness of reinforcement. Then spray the silver compound solution (3) on the surface of the calcium alginate non-woven fabric layer, so that the silver ions are adsorbed on the calcium alginate fibers.

Embodiment 2

[0019] Similar to the method of Example 1, such as figure 2 As shown, the non-woven fabric layer in the hemostatic patch of the present invention is made of polyester, viscose mixed non-woven fabric and calcium alginate non-woven fabric, and the coating is made of nano-silver.

Embodiment 3

[0021] Similar to the method of Example 1, such as image 3 As shown, the non-woven fabric layer of the hemostatic patch of the present invention is made of nylon, viscose fiber mixed non-woven fabric and calcium alginate non-woven fabric, and the coating is made of silver compound.

Abstract

A hemostatic plaster having a composite structure and the preparation method therefor. The hemostatic plaster comprises a non-woven fabric layer of mixed hydrophobic fibers and hydrophilic fibers, a calcium alginate non-woven fabric layer (1), and a metallic ion or metallic nano-particle layer coated on the surface of the composite non-woven fabric layer. The hemostatic plaster is hemostatic, analgesic, and anti-inflammatory, and can maintain a moist environment for a wound and enable the wound to heal.

Description

technical field [0001] The invention relates to a medical device, in particular to a hemostatic patch with a composite structure and a preparation method thereof. Background technique [0002] In daily minimally invasive surgical wound hemostatic care, degreased gauze soaked in medicinal liquid is usually applied on the wound or embedded in the wound to stop bleeding, relieve pain, reduce inflammation, maintain a moist environment for the wound, and promote wound healing, etc. effect. In recent years, many patent documents and non-patent documents have disclosed or reported the use of calcium alginate hemostatic dressings and nano-silver calcium alginate hemostatic dressings. [0003] The advantage of the calcium alginate hemostatic dressing is that the fibers in the calcium alginate non-woven fabric exchange with the sodium ions in the wound exudate and blood to release calcium ions, which can accelerate the formation of blood clots in the capillary ends. As the amount of...
