Catheter Airflow Resistance Tester

• 

Compliance Standards YY0461 - 2003. etc. Main Uses The catheter airflow resistance tester is an important tool for evaluating the resistance of gas flow in catheters. It is specifically designed to measure the airflow resistance inside medical devices such as breathing catheters. It is widely applied in multiple fields, including medical care, environmental protection, and the chemical industry. Especially in the production and quality - control processes of medical devices, this tester plays a crucial role. Through testing, it can ensure that catheter - related products like breathing tubes can meet the predetermined performance standards, thereby improving the overall product quality and production efficiency. In the medical field, the tester is used to assess the performance of breathing circuits for anesthesia machines and ventilators, ensuring that the products meet relevant standards and requirements. Technical Parameters The technical parameters of the catheter airflow resistance tester may vary depending on the model and brand, but the following are some common parameter ranges: Pressure Measurement Range: Usually between 0.01kPa and 10kPa, with an error not exceeding ±1% and a display resolution of 0.01kPa. This range can cover the measurement requirements for the airflow resistance of most catheters. Flow Measurement Range: The flow output range may be from 0L/min to 50L/min, depending on the model of the tester. This range allows for testing the airflow resistance of catheters under different flow conditions. Test Duration: The test duration is usually between 1 second and 10 minutes, with an error not exceeding ±1 second. This time range ensures the accuracy and stability of the test. Accuracy: The accuracy of the tester is a key indicator for evaluating its performance. Generally, the accuracy of pressure measurement is ±0.01kPa, and the accuracy of flow measurement is ±2.5% (or lower, depending on the specific model).
