Endoscopic biopsy forceps is a medical device used to collect tissue samples during endoscopic examinations. Because it is in direct contact with the patient's tissue, it must be strictly disinfected before and after use to prevent cross infection and ensure the safety of the patient. This article will introduce the disinfection process of endoscopic biopsy forceps in detail.
1. Preliminary cleaning
Before disinfection, the endoscopic biopsy forceps must first be preliminarily cleaned. The purpose of this step is to remove blood, tissue fragments and other contaminants on the surface. The specific operation is as follows:
1. Rinse the biopsy forceps with running water to ensure that all visible contaminants are washed away.
2. Use a soft brush to carefully scrub all parts of the biopsy forceps, especially the jaws and joints.
3. Use a high-pressure water gun to rinse the internal channels of the biopsy forceps to ensure that the internal contaminants are also removed.
2. Enzyme washing
Enzyme washing is an effective cleaning method that can decompose proteins and other organic substances, thereby cleaning the biopsy forceps more thoroughly. The specific operation is as follows:
1. Correctly configure the cleaning solution according to the ratio of the multi-enzyme solution.
2. Soak the dried endoscopic biopsy forceps in an enzyme washing tank for 5 minutes, or use an ultrasonic cleaner to wash for 5-10 minutes.
3. Rinse the biopsy forceps thoroughly with running water to ensure that all the enzyme washing solution is washed away.
3. Disinfection
Disinfection is the most critical step in the cleaning and disinfection process of endoscopic biopsy forceps. Commonly used disinfection methods include chemical disinfectant soaking and high temperature and high pressure sterilization. The specific operations are as follows:
1. Chemical disinfectant soaking:
- Select a suitable chemical disinfectant, such as peracetic acid, glutaraldehyde, etc.
- Immerse the biopsy forceps completely in the disinfectant to ensure that all parts are exposed to the disinfectant.
- Soak for a sufficient time (usually 15-30 minutes) according to the instructions of the disinfectant.
- Rinse the biopsy forceps thoroughly with running water to ensure that all the disinfectant is washed away.
2. High temperature and high pressure sterilization:
- Place the biopsy forceps in a high temperature and high pressure sterilizer.
- Set the appropriate temperature and pressure (usually 121°C, 1 atmosphere).
- Sterilization time is usually 15-30 minutes, the specific time is determined according to the equipment manual.
- After sterilization, remove the biopsy forceps and cool naturally.
4. Final cleaning
After disinfection, final cleaning is required to ensure the cleanliness of the biopsy forceps. The specific operation is as follows:
1. Rinse the biopsy forceps again with running water to ensure that all disinfectant residues are washed away.
2. Use a soft brush to carefully scrub all parts of the biopsy forceps, especially the jaws and joints.
3. Use a high-pressure water gun to rinse the internal channels of the biopsy forceps to ensure internal cleanliness.
5. Drying and storage
Finally, the endoscopic biopsy forceps need to be dried and stored. The specific operation is as follows:
1. Use a lint-free cloth or air dryer to thoroughly dry the outside and internal channels of the biopsy forceps.
2. Put the dried biopsy forceps in a dedicated instrument box to avoid confusion with other instruments.
3. Store the instrument box in a dry and clean environment, away from direct sunlight and moisture.
Conclusion
The disinfection process of endoscopic biopsy forceps is a complex and meticulous process that needs to be carried out strictly in accordance with the operating procedures. Only in this way can the cleanliness and safety of the biopsy forceps be ensured, thereby protecting the health of patients and medical staff. I hope that the introduction of this article can help medical staff better master the disinfection method of endoscopic biopsy forceps and improve the quality and level of medical services.
