Sphygmomanometer and Sphygmomanometer Resistance Tester
2026-03-25 09:35WY-009 Sphygmomanometer and Sphygmomanometer Resistance Tester (vieleader)
WY-009 is a specialized testing device for alternating pressure resistance of medical sphygmomanometers independently developed by vieleader. It is designed to verify the material and structural durability of pressure-bearing components of sphygmomanometers, in compliance with national medical device standards such as GB and YY.
I. Core Purpose & Working Principle
1. Applicable Objects
• Manual/electronic sphygmomanometers (arm-type, wrist-type)
• Used for pressure alternation fatigue testing and indication stability verification
2. Testing Principle
The tested device is placed in an alternating pressure environment (2.7–37 kPa / 20–280 mmHg) and undergoes cyclic pressurization and depressurization at a frequency of (30±5) cycles per minute. After the test, the device is left to stand for 1 hour, followed by indication calibration to check if the error meets the requirement of ±0.5 kPa.
3. Executive Standards
• Complies with national medical device standards such as GB 3053
• Compatible with testing methods specified in YY, ASTM and other standards

IV. Typical Testing Process
1. Install the tested sphygmomanometer and connect the air circuit
2. Set parameters on the touch screen: alternating pressure range, frequency and total duration
3. Start the test; the device automatically performs cyclic pressurization and depressurization
4. The device stops automatically and sends a prompt upon completion of the test
5. Conduct indication error calibration after leaving the device to stand for 1 hour
6. Print and save test data and conclusions

V. Application Scenarios
