Technical Field

The invention belongs to the technical field of auxiliary agents for medical instruments, and particularly relates to a medical adhesive remover and a preparation method thereof.

Background

Along with the popularization of the overall supply concept of the hospital disinfection supply center, the CSSD standard is stronger and stronger, and the cleaning quality of medical instruments is more and more emphasized. The cleaning quality of the instruments is a precondition for successful disinfection and sterilization of the instruments. In actual clinical use, common pollutants (such as blood, body fluid, secretion and the like) on the surface of the medical instrument can be cleaned by the multienzyme cleaning agent. However, the residual glue left on the surface of the apparatus, the surface of the working table, the surface of the equipment and the like by the adhesive products such as medical packaging tapes, labels and the like is difficult to clean by a multienzyme cleaning agent.

At present, the main methods for removing the residual gum include a solvent method, an emulsion method, high-pressure water equipment cleaning, dry ice equipment cleaning and mechanical brushing. Most of raw materials used in the cleaning by the solvent and emulsion method are non-environment-friendly solvents such as tetrachloroethylene, ethyl acetate and the like, all of the solvents belong to toxic solvents, and the solvents can cause liver damage by human body inhalation, can cause dermatitis, eczema and the like, can even cause death of serious patients and can cause serious harm to the environment. Although the cleaning method of the high-pressure water and the dry ice is safe and environment-friendly and can thoroughly and quickly remove the glue scales, the initial investment of the equipment is large, and the method is not suitable for popularization and application. The portable cleaning machine has the problem of incomplete cleaning. [ environmental protection type degumming agent for Chinese patent CN 102260599B ]

Based on the above situation, the medical adhesive remover for medical instruments, which has a good adhesive removing effect, is environment-friendly, safe and convenient to operate, has a great market prospect.

The medical degumming agent disclosed by the invention is composed of the following raw materials in percentage by weight:

preferably, the medical degumming agent consists of the following raw materials in percentage by weight:

preferably, the medical degumming agent consists of the following raw materials in percentage by weight:

preferably, the surfactant is one or two of fatty alcohol-polyoxyethylene ether or alkyl glycoside.

Preferably, the terpene compound is one or more of limonene, D-limonene, terpinene, menthol or terpineol.

Preferably, the solvent is one or more of methanol, ethanol, n-propanol, n-butanol, sec-butanol or tert-butanol.

Preferably, the propellant is one or more of liquefied petroleum gas, propane, n-butane, isobutane, dimethyl ether, dichlorodifluoromethane, trichlorofluoromethane or tetrafluoroethane.

The preparation method of the medical degumming agent comprises the steps of mixing the surfactant, the terpene compound and the solvent, adding the mixture into a tank with a spray valve, and adding the propellant into the tank through the spray valve under the pressure of 0.3-0.8MPa to prepare the medical degumming agent.

The use method of the medical adhesive remover comprises the following steps: uniformly spraying the medical adhesive remover on the surface of the apparatus, the surface of a working table, the surface of equipment and other adhesive residues to enable the adhesive remover to act with adhesive dirt for 2-5 min. According to the similar compatibility principle, the residual glue can be dissolved in the glue removing agent, the glue removing agent can also quickly permeate into glue dirt under the action of the surfactant, so that the stubborn glue dirt is softened and stripped from the surface of an object, then the cleaning cloth is used for lightly cleaning, the residual glue can be removed, the surface state of the medical instrument is not damaged, the problems faced by staff in a disinfection supply center are fundamentally solved, and the working efficiency of the staff is improved.
