Nose Clip For PFT

The Nose Clip For PFT is an auxiliary consumable used during Pulmonary Function Tests (PFT). Its core function is to occlude the patient’s nostrils throughout the test, ensuring all inspiratory and expiratory airflow is delivered exclusively through the mouthpiece, thus yielding more accurate and reliable test results.

During PFT procedures—including Forced Vital Capacity (FVC), Maximal Voluntary Ventilation (MVV), Vital Capacity (VC), and Inspiratory Capacity (IC) tests—any nasal air leakage directly impacts result accuracy. The nose clip effectively prevents airflow shunting and improves test consistency.

Disposable Plastic Nose Clip

The disposable plastic nose clip is designed for scenarios requiring high hygiene standards or quick replacement.

Product Features

● Made of medical-grade plastic for safety and reliability

● Lined with soft sponge pads inside for gentle contact and comfortable wearing

● Lightweight and flexible with moderate clamping force to minimize nasal pressure

● Disposable design prevents cross-infection and simplifies management

● For single-patient, single-use only and discard after use; ideal for physical examination institutions and mass screening scenarios

Scope of Application

The Nose Clip For PFT is mainly used in the following tests:

● Pulmonary Function Test (PFT)

● Forced Vital Capacity (FVC) Test

● Maximal Voluntary Ventilation (MVV) Test

● Vital Capacity (VC) and Inspiratory Capacity (IC) Tests

By occluding nostrils, it guides patients to focus on oral breathing and improves test accuracy.

Usage Instructions

Simply clip the nose clip gently onto the nasal alae to fully occlude the nostrils. The inner sponge pads of plastic nose clips conform to nasal contours, ensuring tight closure without causing obvious pressure.

Compared with manual nose pinching, the nose clip reduces operational interference and helps patients focus better on breathing coordination during testing.
