The invention discloses a catheter airflow resistance testing device, comprising a smart control machine table, a test fixture and a pipeline curvature adjustment device. The smart control machine isconnected with the test fixture and the pipeline curvature adjustment device through utilization of signal lines. The device has the beneficial effects that ventilation flow correction of a pipeline can be automatically finished; complex manual adjustment work is simplified; testing time is reduced; through utilization of a pagoda joint device, reliability of a clamp is ensured; testing accuracy is improved; a smart control interface is convenient for use; a testing result is automatically recorded and stored; whether a catheter is qualified or not is judged; and testing efficiency is greatlyimproved.
Description
technical field [0001] The invention relates to an airflow resistance testing device, in particular to a duct airflow resistance testing device. Background technique [0002] Nasal oxygen inhalation is an important treatment method in oxygen inhalation therapy, and patients with different diseases have different needs for catheters. The airflow resistance performance of the catheter is an important part of judging whether the catheter is qualified or not. At present, most enterprises or testing institutions still use the random inspection method for the airflow resistance test of ducts, and manually adjust the instruments and meters for testing. Every time a duct is replaced, it takes a lot of preparation work. There are large human intervention factors in manual testing, it is difficult to ensure the consistency of testing, and the testing efficiency is low. Therefore, there is an urgent need for an intelligent detection device that can safely, quickly, accurately and rel...
