Disinfectant with low corrosiveness

Abstract

The invention provides a disinfectant with low corrosiveness. The disinfectant comprises the following components by weight percent: 0.2-2.0% of ortho-phthalaldehyde, 1-10% of a synergist, 10-50% of a cosolvent, 0.5-5% of a buffering agent, 1-10% of a penetrant, 0.2-2% of a corrosion inhibitor, 0.1-5% of a chelating agent, 0.1-3% of a stabilizing agent and 45-80% of purified water. After the disinfectant is used, intestinal tract pathogenic bacteria, pyogenic coccus, hepatitis virus, H7N9 avian influenza virus, black variant spores of bacillus subtilis and other pathogenic microorganisms can be killed within a short time. Furthermore, the disinfectant adopts a slow release technique, thus having extremely low corrosiveness on metal and being very suitable for disinfecting medical equipment.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a low-corrosive disinfectant. Background technique [0002] With the improvement of medical technology and the development of health services, there are more and more types of clinical surgical instruments. Surgical instruments are high-risk items that frequently come into contact with patients’ body fluids and tissues, and are prone to accidents during use, cleaning, and disinfection. Rust spots are not easy to remove, which not only affects the service life of surgical instruments, but also is difficult to achieve effective sterilization effects, cannot ensure the quality of surgical instruments, and easily causes iatrogenic infections. The use of strong corrosive disinfectants for disinfection will cause strong corrosion to medical devices. The main hazards are as follows: 1. Affect wound healing or infection. If rusty devices touch the wound, it will cause wound healing rate Red...

[0002] With the improvement of medical technology and the development of health services, there are more and more types of clinical surgical instruments. Surgical instruments are high-risk items that frequently come into contact with patients’ body fluids and tissues, and are prone to accidents during use, cleaning, and disinfection. Rust spots are not easy to remove, which not only affects the service life of surgical instruments, but also is difficult to achieve effective sterilization effects, cannot ensure the quality of surgical instruments, and easily causes iatrogenic infections

The use of strong corrosive disinfectants for disinfection will cause strong corrosion to medical devices. The main hazards are as follows: 1. Affect wound healing or infection. If rusty devices touch the wound, it will cause wound healing rate Decreased, prolonged course, severe tetanus infection capable of forming deep wounds

2. Increase the pain of patients, rusty instruments have poor performance, such as blades and scissors become blunt, which increases the friction on the skin and increases the pain of patients

Its main component for disinfection and sterilization is glutaraldehyde, and alkyl benzyl ammonium chloride is added as a synergist. Although it can improve the shortcomings of traditional glutaraldehyde disinfectants that need to be activated and cumbersome to use, the disinfection Disinfectant does not solve the shortcomings of glutaraldehyde disinfectant's high toxicity and strong corrosiveness

Chinese patent CN101828551A discloses a stable peracetic acid disinfectant, which improves the stability of peracetic acid disinfectant to a certain extent, but adds glacial acetic acid and concentrated sulfuric acid to the disinfectant, making the disinfectant highly corrosive

Chinese patent application CN1582661A discloses a kind of solid chlorine dioxide disinfectant, because of adding oxalic acid and citric acid, make this solid chlorine dioxide disinfectant have stronger corrosiveness equally
