PFT Filter

The Spirometer Mouthpiece PFT Filter supplied by Jianeng is specifically designed for pulmonary function testing equipment. During testing, it forms a stable microbial barrier. While maintaining extremely low airflow resistance and minimal dead space, the product effectively reduces the risk of cross-infection, helping healthcare professionals obtain reliable and accurate test results. The product is sterile and ready for use, making it suitable for bulk purchasing and long-term supply.

Product Purpose

Installed between the pulmonary function testing equipment and the patient, the Pulmonary Filter filters the gas exhaled and inhaled by the patient. Without hindering airflow passage, the filter effectively blocks bacteria and viruses, reducing cross-contamination between patients and between patients and healthcare personnel. This ensures the accuracy of test results such as vital capacity, lung volume, and DLCO (Carbon Monoxide Diffusion Capacity).

Product Features

● Low-Resistance Structure: Low pressure drop at specific flow rates ensures smooth testing without affecting results.

● Low Dead Space Design: Meets the dead space volume requirements for lung volume and DLCO testing.

● High Filtration Efficiency: Bacteria and virus filtration efficiency both reach 99.99%.

● Integrated Mouthpiece: Comes with a built-in mouthpiece for direct use, featuring simple operation.

● Patient Comfort: Ergonomically designed to suit testing for different populations.

● Multiple Configurations: Optional disposable nose clips and various interface specifications to adapt to diverse pulmonary function testing needs.

Structure & Materials

The filter shell is made of ABS material, offering stable strength and reliability. The filter layer adopts electrolytic cotton material for consistent filtration performance. Available in multiple interface sizes (ID/OD), it is compatible with various mainstream pulmonary function testing equipment across different brands and models.

Application Scenarios

Widely used in hospitals, physical examination centers, outpatient clinics, and other facilities. During use:

1.Connect one end of the filter to the testing equipment pipeline.

2.The patient wears a nose clip to occlude the nostrils.

3.Hold the filter mouthpiece in the mouth and close the lips tightly.

4.Perform deep breathing and rapid exhalation through the mouthpiece, ensuring all airflow passes through the filter to complete the test.

It provides a stable and safe environment for the testing process.
