Abstract

The invention discloses a medical adhesive, comprising the following substances in parts by weight: 65-80 parts of alpha-N-butylcyanoacrylate, 5-8 parts of hydroxypropyl methacrylate, 3-5 parts of sulfur dioxide, 1-2 parts of hydroquinone, 0.5-2 parts of polyurethane, 0.5-1.5 parts of agar, 0.8-1.2 parts of fibrin glue, 2-3 parts of water soluble phenol-formaldehyde resin, and 20-25 parts of deionized water. The medical adhesive has the beneficial effects that the medical adhesive provided by the invention is low in thrill, and excellent in bonding persistence; compared with the traditional common adhesive, the persistence of the medical adhesive can be up to 1.5-3 times; and animal experiments show that the toxic and side effects are small.

Description

Technical field [0001] The invention involves a medical adhesive. Background technique [0002] The use of medical adhesives has a long history, but it has not developed rapidly until recent decades.There are many types of medical adhesives. According to the nature of their materials, they can be divided into chemical adhesives and bioparies.According to its purpose, its adhesion is involved in the following aspects of the human biological cells: (1) the adhesion between cells;Bonding between external substances.The specific classification is: adhesives, dental adhesives, orthopedic adhesives and skin compression glue for soft tissue.The medical adhesives that are commonly used a few days ago are more or less stable in stimulating, and the adhesive durability is not strong. Invention content [0003] The purpose of the present invention is to provide the defects in the above existing technologies, providing non -irritating and excellent adhesive medical adhesives. [0004] In or...
