1. Regular Replacement Cycle
2-3 Years: As a consumable item, the cuff may experience loss of elasticity, closure failure, or aging of the cuff after prolonged use. It is recommended that the cuff be inspected and replaced every 2-3 years.
10,000 Measurements: Some manufacturers recommend a cuff lifespan of 10,000 measurements (under standard test conditions). Replacement is required after this number.
2. Situations Requiring Immediate Replacement
Significant Wear or Tearing: Damage to the cuff surface, cuff leaks, or loss of elasticity can lead to measurement errors and require immediate replacement.
Hygiene Issues: The cuff easily accumulates dirt in contact with the skin. If odor or contamination persists after cleaning, it is recommended that it be replaced to avoid the risk of infection.
3. Precautions for Special Populations
Patients with Atherosclerosis: Check the cuff more frequently to ensure it fits correctly and is leak-free. This can prevent distorted blood pressure readings due to cuff issues. Children or obese individuals: Use a dedicated cuff and shorten the measurement interval, as an incorrect cuff size can significantly affect measurement accuracy.
4. Maintenance and Calibration Recommendations
Regular Cleaning: Wipe the cuff surface with an alcohol pad. Cloth cuffs are removable and washable, but they must be thoroughly dried.
Calibration Comparison: If measurement results differ significantly from those obtained with hospital equipment, inspect the cuff or replace the equipment.
5. Other Influencing Factors
Frequency of Measurement: Frequent use (such as in medical institutions) requires a shorter replacement interval.
Environmental Factors: High temperatures or humidity may accelerate cuff aging and require premature replacement.
