What safety precautions should be taken when lubricating medical casters?

Safety Guidelines for Lubricated Medical Casters

To ensure the stability of medical equipment and patient safety, strictly adhere to safety guidelines when lubricating casters:

 

Pre-Operation Preparation:

Equipment Securing: Ensure the equipment is completely shut down and powered off (especially electrically powered equipment). Lock the caster brakes and use wheel chocks if necessary to prevent accidental movement or electric shock.

 

Environmental Cleanliness: Operate in a clean, dry area, avoiding the core sterile zone. Clean the equipment surface and casters (e.g., wipe with disinfectant wipes) to prevent contamination. Lay protective mats on the floor to prevent contamination.

 

Personal Protection: Wear disposable non-slip gloves. When using volatile lubricants, wear goggles and a mask.

 

Lubricant Selection and Use:

Strict Selection: Use medical/food-grade lubricants (e.g., silicone-based, PTFE-based) that are non-toxic, non-irritating, non-volatile, corrosion-resistant, and temperature-resistant, and meet medical standards (e.g., ISO 10993). Industrial lubricants/greases are strictly prohibited.

 

Material Compatibility: Ensure the lubricant is compatible with the caster material (especially rubber wheels) to prevent swelling and aging.

 

Dosage Control: Apply a thin layer of lubricant only to friction areas, using a small amount frequently. Clean up any dripping lubricant immediately (e.g., with a dust-free cloth or alcohol) to prevent slipping and contamination.

 

Operational Specifications:

Careful Disassembly and Assembly: Before disassembly, shift the equipment's load and use dedicated tools to prevent tipping or flying parts. After installation, inspect for secure fit, smooth rotation, and braking function.

 

Prevent Cross-Infection:

Disinfect hands and tools before and after operation. Separate casters for equipment in contaminated areas and use dedicated tools. Casters that have come into contact with contaminated equipment must be thoroughly disinfected.

 

Special Scenarios: Lubricate high-frequency/precision equipment during off-peak hours and proceed gently to avoid disrupting emergency operations or damaging the equipment.

 

Cleanup and Disposal:

Dispose of contaminated gloves and wipes as medical waste. Store lubricant in a sealed container away from sources of ignition and food and drug areas.

 

Functional Verification: Test the caster's rotational flexibility and braking effectiveness (no slipping when the brake is applied), and confirm the absence of unusual noise or sticking. Record lubrication details (time, lubricant, operator), and establish a maintenance log.

 

Core Principles: Safety and hygiene first, compatibility and adaptability, and standardized operation. By strictly controlling lubricants, standardizing processes, and focusing on safety precautions, we ensure equipment life and stability, while minimizing risks to personnel and the environment.
