Lubrication standards for roller chains of medical devices: ensuring precision and safety
In the field of medical devices, roller chains are key transmission components, and their lubrication standards are crucial. Reasonable lubrication can not only extend the service life of the chain, but also ensure the precise operation and safe operation of medical devices. The following are the specific standards and relevant points for the lubrication of roller chains of medical devices.
1. Selection of lubricants
Non-toxic and non-irritating: Lubricants for roller chains of medical devices must meet the requirements of biocompatibility to ensure that they are non-toxic and harmless to the human body. Lubricants should pass relevant biosafety tests, such as cytotoxicity, skin irritation and other tests, to ensure that they will not cause harm to patients or medical staff during the use of medical devices.
Chemical stability: Lubricants should have good chemical stability and are not easy to react chemically with other materials of medical devices. In the use environment of medical devices, lubricants should be able to maintain their stable performance and not be easy to oxidize, decompose or deteriorate to ensure long-term and effective lubrication.
Lubricating performance: Lubricants should have excellent lubricating properties, which can effectively reduce the friction coefficient of roller chains and reduce wear. It should have appropriate viscosity, which can not only ensure the formation of a stable oil film during the operation of the chain, but also ensure good fluidity under different temperature conditions.
2. Lubrication method
Manual lubrication: Suitable for some small or low-speed medical device roller chains. The operator can use an oil gun or a brush to evenly apply the lubricant to the joints of the chain and the surface of the roller. The advantages of manual lubrication are simple operation and low cost, but regular inspection and maintenance are required to ensure sufficient and uniform lubricant.
Automatic lubrication system: For medical device roller chains running at high speed or high load, it is recommended to use an automatic lubrication system. The system can deliver lubricant to various parts of the chain in a timely and quantitative manner to ensure the continuity and stability of lubrication. The automatic lubrication system can effectively reduce manual intervention and improve lubrication efficiency and accuracy.
3. Lubrication frequency
Daily inspection: The operator should check the lubrication condition of the roller chain every day to observe whether the lubricant is sufficient, whether it is dry or contaminated, etc. Any problems found should be dealt with in a timely manner to ensure that the chain is always in a good lubrication state.
Regular lubrication: According to the frequency of use and working environment of medical equipment, a reasonable lubrication cycle should be formulated. In general, it is recommended to perform comprehensive lubrication every 50-100 hours of use or at least once a week. For some high-load or high-speed equipment, the lubrication frequency should be appropriately increased.
IV. Performance test after lubrication
Friction coefficient test: After lubrication, the friction coefficient of the roller chain should be tested using a professional friction coefficient tester. Ensure that its friction coefficient is within the standard range to ensure the normal operation and transmission efficiency of the chain.
Wear inspection: Regularly check the wear of the roller chain and observe whether there are obvious signs of wear on the chain plates, rollers, and pins. If severe wear is found, the chain should be replaced or repaired in time.
Noise level test: During the operation of the lubricated roller chain, its noise level should meet the relevant standard requirements of medical devices. Excessive noise may indicate poor lubrication or other problems with the chain, which requires further inspection and treatment.
The lubrication standard of medical device roller chains is an important guarantee to ensure the normal operation and safe use of equipment. Selecting the right lubricant, using the right lubrication method, setting a reasonable lubrication frequency, and conducting strict performance testing are all key links to ensure the lubrication effect of medical device roller chains. Only by following these standards and requirements can the service life of roller chains be effectively extended, the reliability and safety of medical devices be improved, and strong support be provided for the smooth development of medical work.
