Abstract

The invention discloses a new medical material. The new material is prepared from the following raw materials in parts by mass: 80-150 parts of butyl cyanoacrylate, 0.01-0.1 part of hydroquinone, 5-24 parts of aloe nano micro-powder, 20-55 parts of soybean protein powder, 10-44 parts of chitosan, 1-5 parts of acetic acid and 8-18 parts of polyvinyl alcohol. According to the new medical material disclosed by the invention, the impact resistance is enhanced by the aloe nano micro-powder, and the product degradability is improved by the natural plant extraction essence and ingredients; the bacterium inhibiting activity of the product is enhanced by the chitosan component; and the product has the advantages of moderate curing speed, high bonding strength, low heat release in bonding, good toughness of a bonding film and little skin irritation, and realizes a high-strength quick bonding effect on various wounds and operative incisions while avoiding scars after curing.

Description

technical field [0001] The invention relates to a new medical material and belongs to the technical field of medical auxiliary products. 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 m...
