What are the aspects of quality control for cleaning of animal medical devices and orthopedic surgical instruments?

Quality control of cleaning of animal medical instruments and orthopedic instruments

Quality control of manual cleaning of animal medical instruments

1. The concept of manual cleaning

Manual cleaning is done by physical means, and water flows into the instrument, and the contaminated detergent is used to remove the dirt attached to the instrument with a clean cloth or brush to achieve the purpose of cleaning.

2. Scope of application

1. Preliminary analysis and treatment of serious environmental pollution items.

2. Precision and complex instruments should be cleaned by hand before mechanical cleaning.

3. Items that cannot be soaked in water for a long time.

4. Mechanical cleaning equipment cannot be used in this method.

3. Quality control before manual cleaning

1. Preparation before manual cleaning of animal medical equipment

Do your own occupational safety protection technical operation and management personnel should Wear a hat, mask, special waterproof shoes, protective mask or goggles, waterproof protective clothing or apron and sleeves, and rubber gloves or puncture-resistant latex examination gloves. Operators with wounds on their hands should avoid participating in the cleaning of equipment.

(3) Pretreatment before cleaning and pretreatment before manual cleaning are essential links.

The instrument can include equipment for checking cleanliness grading during the moisturizing process, Special disinfection of contaminated utensils, etc.

① Before cleaning the instrument, it should be completely immersed in multi-enzyme solution water at 40°C for 5 to 10 minutes to melt or loosen the dirt attached to the instrument.

② Disassembly: For some instruments with a relatively complex economic structure, a joint should be opened before soaking. Instruments that can be disassembled should be fully disassembled. If there is a lumen, the tube core should be pulled out to avoid washing work by students. Face covering. If the degreasing device is heavily contaminated with oil, a suitable solvent should be used for pretreatment.

④ Use a disinfectant containing 2000 mg/L of chlorine to disinfect special instruments. Contaminate special instruments and soak them on the surface of the instrument to initially kill pathogenic microorganisms.

IV. Quality control of manual cleaning of animal medical devices

1. Classification

(1) Open the market recycling data sorting box, check the devices, and classify them by device Waste classification can be carried out by different materials, shapes, or by arranging the instruments in a single instrument package as a unit without cleaning.

(2) The type and degree of equipment polluted by device pollutants, and the classification process.

(3) Place the classification of animal medical equipment in one step to reduce the number of repeated contacts of staff with contaminated instruments, or by loading multiple containers, such as various baskets , preparation of instrument supports, etc., can be counted in classifying requirements for next cleaning based on placement in different containers so that employees do not need to come into direct contact with contaminated equipment during transportation.

(4) Employees who classify contaminated items and equipment are prohibited from touching with bare hands. Pay attention to your own professional and technical safety protection to avoid occupational exposure in the enterprise.

(5) The washing water temperature is set between 15℃ and 30℃.

2. Flushing

Put the instruments, utensils and items in the company's flow for underwater flushing, which can initially remove dirt. Tube-type instruments are flushed with a high-pressure water gun.

According to the degree of contamination, type, and characteristics of the equipment 3. Treatment of animal medical equipment

(1) First, use dry enzyme-containing dyeing equipment to wash the solution, and then soak or scrub.

4. Rinse

After washing, use company running water to rinse or brush.

5. Final rinse

Soft water, purified water or distilled water should be used for rinsing.

6. Precautions for rinsing

(1) It is necessary to confirm that the instrument has been scrubbed and the quality has reached the requirements, and then we can choose to use running water to rinse the instrument information thoroughly. . When flushing, pay attention to the inner wall, joint surface, occlusal surface and other parts to be fully flushed.

(2) Precious ones should be placed separately from rinsing with ordinary equipment to prevent damage and loss of fine and small instruments.

7. Cleaned instruments should be processed by corresponding disinfection methods in a timely manner

(1) Thermal disinfection such as boiling or low-temperature steam sterilization.

(2) Disinfect with 75 ethanol, acidic oxidation potential water or sanitary approved disinfectant.

8. Drying instruments

(1) Use ethanol and other EOW-sterilized instruments, rinse them again with soft water, purified water or distilled water, and place the instruments in a basket for human cleaning, dry or dry Box of cotton batting fiber cloth one inside one with low direct drying.

(2) Thermal disinfection equipment is directly put into the drying cabinet for drying.

(3) Dry the lumen instruments with a high-pressure air gun.
