The use of silver for antibacterial and anti-corrosion purposes by humans has a history of thousands of years, and silver ions have been used for clinical antibacterial treatment for over half a century. Its safety and effectiveness have been widely recognized. Nano silver medical dressings use patented technology to nano scale silver, making its particle size reach the nanometer level, with a larger specific surface area and a qualitative leap in bactericidal effect. Its characteristics and advantages include:

Nano silver medical dressings have inhibitory and bactericidal effects on various pathogenic microorganisms. Common pathogens on burn wounds include Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. It also has antibacterial activity against drug-resistant bacteria.

The characteristics and advantages of sterilization of nano silver medical dressings:

By slow-release silver ions, they exert antibacterial effects. After killing bacteria, silver ions can be released from the bacterial body to continue to exert antibacterial effects, thus exhibiting long-lasting antibacterial effects.

Has stronger bactericidal power when exposed to water. Nano silver medical dressings are made using patented technology and have an outer protective film that dissolves and releases active ingredients when exposed to water. Therefore, it has higher release activity and stronger antibacterial activity in humid environments. This characteristic is more in line with the law of wound healing. The antibacterial mechanism of nanosilver is completely different from that of antibacterial drugs. It mainly enters the bacterial body and forms irreversible sulfur silver compounds with - SH enzymes, binding SH and interfering with microbial respiration, leading to bacterial death. Its unique bactericidal mechanism makes it less prone to developing drug resistance.

Excessive MMP activity in wounds can damage growth factors and new tissue, hindering healing. Its activation requires the participation of zinc ions. The silver ions released by nanosilver burn and burn patches (another type of trauma patch specifically designed for treating burns and burns) can bind to the thiol groups in the MMP structure or reduce the zinc ion on the wound surface by exchanging with zinc ions, thereby reducing excessive MMP activity. Thus promoting wound epithelial regeneration, accelerating wound healing, and reducing scar formation.

Usage:

A. For some plastic surgery, minimally invasive surgery, and patients who do not need to be hospitalized, different specifications of nano silver medical dressings are selected according to the size of the surgical incision after the surgery. When using, after completing the surgery (some require suturing), the nano silver medical dressings are directly applied. Due to the adsorption layer of the nano silver medical dressings, they have a certain adsorption effect on the exudate, and patients can go home for rest, When it is necessary to withdraw the suture, go to the hospital for withdrawal. After the doctor withdraws the suture, moisten the incision site with physiological saline, and then replace it with a nano silver trauma patch. The patient can directly remove it at home for 6-8 days after returning. So this type of surgical incision usually takes 2 pieces from the time of surgery to wound healing, with 1 piece in the first 3-5 days and 1 piece in the last 6-8 days.

B. For patients with long surgical incisions that require hospitalization, after the surgery, the doctor selects a suitable specification of nano silver trauma patch according to the length of the surgical incision. When using, it can be directly applied to the incision site. Due to the adsorption layer of the nano silver trauma patch, it has a certain adsorption effect on the exudate. If there is a lot of exudate from the incision on the hand, a catheter or gauze should be used for drainage, In general, it should be changed every 2-3 days. When the suture is removed or 3-7 days later, the patient should be discharged from the hospital and removed at home for 6-8 days. Therefore, from the entire surgical incision to wound healing, 3 pieces are sufficient. One piece is needed for the first 2-3 days, one piece is needed for the last 3-7 days, and one piece is needed for discharge.

1、 Precautions

Whether it is a burn wound or various surgical incisions, when using nano silver burn and burn patches and nano silver trauma patches, we do not need to disinfect the wound with alcohol, iodine, red mercury water, etc. We only need to clean the wound with physiological saline or wet the nano silver product on the patch. There is no need to disinfect the wound in other ways during replacement, Simply moisten the wound with physiological saline and replace it with nano silver products as needed.

2、 Characteristics of the efficacy of nano silver trauma patches

A. Broad spectrum antibacterial (nano silver has inhibitory and bactericidal effects on over 650 harmful bacteria)

B. Durable antibacterial effect (after contact with fresh wounds, the nano silver dressing continuously sustains the release of nano silver ions in a moist and exudate environment, making its antibacterial effect long-lasting)

C. Stronger bactericidal effect when exposed to water (when exposed to water or secretions, exudates, or sweat from wounds, nanosilver slowly releases its active ingredients, maintaining an effective bactericidal concentration on the wound for a long time, enhancing its antibacterial power)

D. No drug resistance (nanosilver has a nanoparticle diameter of less than 25nm, mostly 3-5 nanometers; nanosilver has a different antibacterial mechanism from other ordinary antibiotics, with a large specific surface area, strong activity, and easy entry into bacteria that are tens of times larger than it. It binds with its protease to denature and directly kill bacteria, making it less likely to develop resistance)

E. Repair and regeneration (Nano silver specifically promotes the regeneration of epithelial cells in wounds, has the function of generating muscle, promoting tissue repair and regeneration, accelerating wound healing, shortening healing time, and reducing scar production)

F. Safe and non-toxic (through extensive clinical and animal toxicity trials, it has been shown that nanosilver has a low dosage and is a safe medication method with no toxicity or side effects).
