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 bl
