Electronic Blood Pressure Monitor Airtightness Testing Solution

1. Why is Airtightness Testing Necessary for Electronic Blood Pressure Monitors?

As a medical diagnostic device, the airtight performance of an electronic blood pressure monitor directly affects its measurement accuracy and reliability. Poor airtightness can lead to the following issues:

Issue Consequence
  • Increased measurement error
Leakage causes pressure drop, leading to lower blood pressure readings
  • Shortened device lifespan
Continuous leakage overworks the air pump
  • Safety risks
Severe leakage may cause abnormal cuff inflation
  • Non-compliance with medical standards
Fails certification standards such as YY 0670 and ISO 81060

A complete airtightness testing system ensures that every unit meets the medical accuracy requirements before leaving the factory. If you need a custom testing solution for your product, our medical testing specialists can provide expert consultation.

2. Detailed Professional Testing Solution

Comparison of Testing Methods

Testing Method Detection Sensitivity Features Applicable Areas
Direct Pressure Decay Method ±1 mmHg Pressure range: 0–300 mmHg (expandable to 500 mmHg) Complete pneumatic system testing
Differential Pressure Method ±0.5 mmHg Ideal for detecting micro-leaks Key sealed components (e.g., valves, joints)
Flow Testing Method Quantifies leak rate -- Air pump output performance testing

3. Typical Testing Process

Using an upper-arm electronic blood pressure monitor as an example:

Testing Stage Specific Steps
Pre-treatment Stage Device self-check and zero-point calibration
Select the corresponding testing program (adult/child mode)
Connection Stage Quick-connect the monitor's air port to the fixture
System auto-identifies device type
Testing Stage Auto-inflation to preset pressure (usually 200 mmHg)
Pressure stabilization for 10 seconds before testing
Monitor pressure decay within 60 seconds
Evaluation Stage System compares measured value with standard value
Auto-generate test report
Result notification via sound/light signal

4. Conclusion

Rigorous airtightness testing is a key step in ensuring that electronic blood pressure monitors comply with medical standards and deliver accurate measurements. Our solutions meet both domestic (YY 0670) and international (ISO 81060) standards and can be customized to your specific needs—helping medical device manufacturers improve product quality and reduce after-sales risk.
