Embodiment 1

[0027] The disinfection process of the gauze, medical middle sheet and hole towel prepared by the grass fiber medical material provided by the present embodiment is as follows:

[0028] Take out the gauze, medical drapes, and hole drapes that need to be sterilized from the medical surgical bag, and put them into a disposable degradable packaging bag with a dialysis port for packaging.

[0029] Put the packed gauze, medical drapes, and hole drapes into the 6m 3 Sterilization was carried out in a sealed ethylene oxide sterilizer, automatic heating was selected, the temperature of the water tank was controlled at 54°C, and the temperature of the box body was 50°C. At the same time, open the vacuum pump and vacuum valve, the vacuum pressure reaches minus 30kPa, close the vacuum valve and vacuum pump, and observe the pressure gauge for 2-3 minutes after closing, if the pressure does not change, and the fluctuation value is about 3kPa, you can add ethylene oxide. Sterilize. Open t...

Embodiment 2

[0039] The disinfection process for preparing degradable sutures from polylactic acid materials provided in the embodiments of the present invention is as follows:

[0040] Environmentally friendly polylactic acid materials are used to prepare degradable sutures, and the degradable sutures prepared from polylactic acid materials that need to be sterilized are packed into disposable degradable packaging bags with dialysis ports.

[0041] Put the degradable suture made of polylactic acid material into 6m 3 Sterilization was carried out in a sealed ethylene oxide sterilizer, automatic heating was selected, the temperature of the water tank was controlled at 56°C, and the temperature of the box body was 51°C. At the same time, open the vacuum pump and vacuum valve, the vacuum pressure reaches minus 31kPa, close the vacuum valve and vacuum pump, and observe the pressure gauge for 2-3 minutes after closing, if the pressure does not change, and the fluctuation value is about 3kPa, yo...

Embodiment 3

[0050] The disinfection process of the chitin medical dressing provided by the embodiment of the present invention is:

[0051] Take the environmentally friendly chitin-based medical dressing, and pack the chitin-based medical dressing that needs to be sterilized into a disposable degradable packaging bag with a dialysis port.

[0052] Put the packaged chitin-based medical dressing into 6m 3 Sterilization was carried out in a sealed ethylene oxide sterilizer, automatic heating was selected, the temperature of the water tank was controlled at 58°C, and the temperature of the box body was 52°C. At the same time, open the vacuum pump and vacuum valve, the vacuum pressure reaches minus 32kPa, close the vacuum valve and vacuum pump, and observe the pressure gauge for 2-3 minutes after closing, if the pressure does not change, and the fluctuation value is about 3kPa, you can add ethylene oxide. Sterilize. Open the dosing valve, add ethylene oxide for 30 minutes, slowly add 5 kg of...

Abstract

Embodiments of the invention disclose a disinfection method for environment-friendly medical materials. The method includes the following steps: performing sterilization disinfection on the environment-friendly medical materials by using epoxyethane in an environment of pressure of -30 kPa or below and temperature of 54-58 DEG C. According to the disinfection method for the environment-friendly medical materials such as Hesu fiber (based on PHBV) materials, degradable carbon dioxide copolymer materials, polylactic acid materials and chitin materials provided by the embodiments of the invention, the addition amount of the epoxyethane and the sterilization time in the sterilization process are controlled to realize the purpose of sterilizing the environment-friendly materials; in addition, the method provided by the embodiments of the invention quickly reduces the residual amount of the epoxyethane by adjusting and controlling temperature, humidity and pressure during forced desorption and performing suction for multiple times, and makes the environment-friendly medical materials achieve a clinical safety use standard through natural desorption; and the disinfection method provided by the embodiments of the invention is convenient for disinfection, and has strong sterilization ability and a wide range of application.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical disinfection, in particular to an environment-friendly disinfection method for medical materials. Background technique [0002] Hospitals use some medical materials in the process of treating patients for the purposes of protection, disinfection, hemostasis, wound treatment, surgical suture, and prevention of tissue adhesion. These medical materials are roughly divided into two categories: 1. In vivo use Materials such as: hemostatic sponge, hemostatic gauze blocks, surgical gauze balls, surgical wound accessories, etc.; , medical cotton, bandages, cotton balls, cotton swabs, etc. In order to prevent infection and cross-contamination, the above-mentioned medical materials need to be sterilized before use. The disinfection methods for the above-mentioned medical materials include: ethylene oxide sterilization method for high-pressure steam sterilization of disposable medi...
