Abstract

The invention discloses a novel medical material. The novel medical material is prepared from the following raw materials in parts by mass: 80 to 150 parts of butyl cyanoacrylate, 0.01 to 0.1 part ofhydroquinone, 5 to 24 parts of aloe nano-micro powder, 20 to 55 parts of soybean protein powder, 10 to 44 parts of chitosan, 1 to 5 parts of acetic acid, 8 to 18 parts of polyvinyl alcohol, 2 to 4 parts of styrene butadiene latex, 2 to 5 parts of ethoxyethanol, 2 to 5 parts of dimethyl ether, 2 to 5 parts of miconazole nitrate, 2 to 5 parts of thiourea, 0.1 to 0.3 part of tungsten powder, 1 to 5 parts of polyamide, 2 to 7 parts of phenol and 0.5 to 1.0 part of methylimidazole. The product provided by the invention has the advantages of moderate curing speed, high bonding strength, low heat releasing in an adhesion process, good toughness of an adhered thin film and small irritation on skin; the product has high strength and rapid bonding effects on various wounds and surgical incisions andno scars are left after the product is cured.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a new medical material. Background technique [0002] Medical glue is an emerging medical product that replaces sewing needles. The main component of medical glue is a-cyanoacrylate, which has the fastest polymerization speed in biological tissues. Under the action of anions in wound blood and interstitial fluid, medical glue can quickly polymerize and solidify to form a film and inlay tightly with the wound, which can firmly maintain the apposition state of the wound, and the glue film can prevent blood cells and platelets from passing through. Under the joint action of protein, the broken small blood vessels on the wound surface can be effectively stopped bleeding, while the adhesive film isolates the tissue and bacteria, and also has the effect of anti-infection and protection of the wound surface. The ether chain in the polymer also has analgesic effect, so medical glue ...
