Air leak test of medical artificial lung

Case Shows

With the development of industrialization, there are more and more lung diseases, and the application of artificial lungs in lung diseases is becoming more and more important.


The human respiratory system inhales oxygen from the outside air, to make oxygen entering into the lungs and blood, and then transports it to all parts of the body for use. On the other hand, carbon dioxide in the blood of the lungs permeates into the air bubbles and is excreted out of the body. The inhaled air travels along the branches of the bronchi in the lung lobes to reach the alveolar formed at the ends of the smallest branches of the bronchi.

The artificial lung needs to have the function of the real lung, so that the blood can flow in the cavity without leaking out.

Therefore, the manufacturer needs to test the air leak of the artificial lung before leaving the factory.


Air leak test process

Testing machine: HC classic series air leak tester



Solution: Design the mold and tooling according to the shape of the artificial lung and customer needs.


Using the direct test method, put the artificial lung into the mold, press the start button, the instrument enters the test program, the test pressure is 10Kpa, the inflation time is 15s, the voltage stabilization time is 15s, and the test time is 5s. The upper limit of leakage is 0.05Kpa.
