Problems solved by technology

[0003] At present, the main research direction of medical adhesives is to improve the bonding strength of various adhesives. However, the biomedical materials currently used in surgical operations do not have the function of bacterial immunity, and are prone to bacterial adhesion and reproduction, becoming a source of infection in surrounding tissues. , bringing huge mental and economic pressure to patients, endowing medical materials with antibacterial activity is the only effective way to solve this problem
The production of formaldehyde during the storage and use of cyanoacrylate medical adhesives has side effects on biological tissues, and with the increase of formaldehyde concentration, the damage to organisms increases, which seriously affects the effect and application of medical adhesives

Abstract

The invention relates to a high antimicrobial property medical binder. The high antimicrobial property medical binder is prepared from the following components in parts by weight: 45-55 parts of poly(alpha-isobutylcyanoacrylate-alpha-octyl cyanoacrylate), 24-36 parts of efficient antimicrobial components, 2-5 parts of polyurethane, 20-25 parts of polyisoprene, 2-4 parts of sodium alginate, 3-6 parts of xylogen, 7-10 parts of gallotannic acid, 1 part of a stabilizer, 1 part of a formaldehyde inhibitor, 150-200 parts of seabuckthorn seed oil and 180 parts of sterile water. Three antimicrobial components are specially added to the medical binder, so the medical binder is high in antibacterial rate, high in binding strength, good in biocompatibility, and high in overall curative ratio, and complies with the application requirements to the medical binder clinically.

Description

technical field [0001] The invention belongs to the technical field of medical materials, in particular to a medical adhesive with high antibacterial performance. Background technique [0002] With the advancement of medicine, the clinical requirements for the effect of surgical techniques and auxiliary materials are getting higher and higher. The philosophy of modern medicine is to minimize the suffering of patients and to allow patients to recover as quickly as possible. Medical adhesives are a branch of medical polymers. They use biological tissues as bonding objects. Most of the tissues and organs of the human body Adhesive technology can be used to replace partial sutures and ligation operations during the treatment process without anesthesia; it will automatically fall off after the wound is healed. Compared with traditional methods, the use of medical adhesives can effectively shorten the operation time and reduce the patient's pain. [0003] At present, the main re...
