Nasal Oxygen Cannula Tester

This device is used to test various performance characteristics of nasal cannulas, such as airflow resistance and resistance to kinking. It is also known as a nasal cannula airflow resistance and kinking resistance tester or nasal cannula testing equipment. This device is suitable for all nasal cannulas, whether they are standalone or used in conjunction with humidifiers or masks. It can test parameters such as airflow resistance, resistance to kinking, leakage, pressure resistance, and bending resistance (patency).

Applications

The nasal oxygen tube tester is mainly used to test key parameters of nasal oxygen tubes, such as oxygen content, flow rate, and pressure, as well as to evaluate their physical properties like pressure - resistance, crush - resistance, and air permeability. This tester plays an important role in various aspects, including the production, quality control, and pre - use inspection of nasal oxygen tubes, ensuring that nasal oxygen tubes can provide patients with a stable and effective oxygen supply. Specifically, its main uses are as follows:

- Production Quality Control: During the production of nasal oxygen tubes, manufacturers can use this tester to conduct sampling inspections on finished products, ensuring that each batch of nasal oxygen tubes complies with relevant standards and regulations. - Pre - use Inspection: Before using nasal oxygen tubes, medical institutions can use this tester to conduct quality inspections to ensure that the performance of nasal oxygen tubes is stable, safe, and reliable. - Research, Development and Improvement: The nasal oxygen tube tester can also be used in the research, development and improvement process of nasal oxygen tubes, helping R & D personnel understand the performance characteristics and deficiencies of nasal oxygen tubes, so as to make targeted improvements and optimizations.

Test Procedures

1. Pre-test Preparation

Check that the instrument's power supply and pipeline connections are normal, start the instrument and preheat it to a stable working state.

Calibrate the pressure and flow sensors (refer to the instrument calibration guide) to ensure that the detection accuracy meets the requirements.

Clean the fixtures and pipelines of impurities, prepare the nasal oxygen cannula samples to be tested, and record the basic information of the samples, such as specifications and materials.

2. Sample Installation

Connect the nasal oxygen cannula sample to the corresponding pipeline interface of the instrument, and use a special fixture to fix both ends of the sample, ensuring that the connection is sealed without leakage and that the sample is not bent or displaced.

3. Test Parameter Setting

Through the instrument's touch screen interface, select the target test item (such as airflow resistance, pressure resistance, leakage test, anti-flattening performance, etc.).

According to the corresponding standard for nasal oxygen cannulas (such as YY/T 1543-2017), set the corresponding test parameters (such as test flow rate, pressure threshold, pressure holding time, etc.), and save the parameters after confirmation.

4. Starting the Test

After confirming that the sample connection and parameter settings are correct, click the "Start" button. The instrument will automatically execute the test process, collecting and displaying data such as flow rate, pressure, and time in real time.

5. Test Process Monitoring

During the test, observe the data changes on the instrument interface and the sample status. If any abnormalities such as loose pipelines or leaks occur, pause the test immediately and handle the issue.

6. Test Completion and Cleanup

After the test is completed, the instrument will automatically shut down. Record or export the test data (such as airflow resistance value, pressure resistance results, etc.).

Loosen the fixture and remove the sample, clean the fixture and pipelines, turn off the instrument power, and prepare the test report.
