Disposable Pulmonary Function Filter

Jianeng is a professional Chinese manufacturer with many years of experience in medical filter production, providing stable supply, strict Quality control, and advanced manufacturing capability. The Disposable Pulmonary Function Filter delivers 99.99% microbial filtration with low resistance and low dead space for accurate pulmonary testing. Bulk and Wholesale orders are available with competitive price options, helping customers buy efficiently.

Product Overview

The Disposable Pulmonary Function Filter is a single-use filter specifically designed for pulmonary function testing equipment. It establishes a stable and reliable microbial barrier during testing, maintaining extremely low airflow resistance while effectively reducing cross-infection risks. This helps healthcare professionals obtain accurate and reproducible test data, making it suitable for various pulmonary function testing projects.

Product Purpose

Installed between the pulmonary function testing equipment and the patient, this filter filters exhaled and inhaled gases during testing. Its high-efficiency filter layer blocks bacteria and viruses, reducing cross-contamination between different patients or healthcare personnel. Meanwhile, it does not hinder airflow passage, ensuring the accuracy of test results such as vital capacity, lung volume, and DLCO (Carbon Monoxide Diffusion Capacity).

Product Features

·Low-Resistance Design: Optimized structure with low pressure drop at specific flow rates, ensuring smooth pulmonary function testing.

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

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

·Detachable Mouthpiece: The mouthpiece is separable from the filter body; only the mouthpiece needs to be replaced after use, reducing operational costs.

·Multiple Configurations: Compatible with disposable nose clips, adult mouthpieces, or pediatric mouthpieces to meet the needs of different patients.

·Patient Comfort: Balances usage stability and wearing comfort, minimizing discomfort during testing.

Product Structure & Materials

The shell of the Disposable Pulmonary Function Filter is made of ABS material, ensuring safety and durability. The filter layer adopts electrolytic cotton material for stable and reliable filtration performance. The product offers multiple interface sizes (ID/OD), compatible with various mainstream pulmonary function testing equipment and adaptable to different clinical application scenarios.

Usage & Hygiene Safety

Designed for single-use, it is suitable for a single patient or a single test. After use, it should be directly discarded to avoid infection risks from reuse. The filter is sterilized by ethylene oxide (EO) and delivered as a sterile medical device, meeting the hygiene and safety requirements of medical institutions.

Application Scenarios

The Disposable Pulmonary Function Filter is widely applicable to medical facilities such as hospitals, physical examination centers, and outpatient clinics. During testing:

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, allowing all airflow to pass through the filter to complete the test.

It provides a safer testing environment for both healthcare professionals and patients.
