Spirometer Mouthpiece

Core Product Overview

The Spirometer Mouthpiece is a core consumable for pulmonary function testing equipment, specifically designed for lung capacity and ventilation function testing.

It is a key component ensuring accurate test data. Working in conjunction with the pulmonary function testing equipment, it provides a stable, sealed environment for the user during testing, allowing sound waves to vibrate smoothly and interact with the lungs, ultimately helping the equipment obtain accurate information about lung structure and function.

This Spirometer Mouthpiece requires no additional adapters, is easy to use, and is suitable for various routine pulmonary function testing scenarios. It is a commonly used consumable in medical testing institutions and health check-up centers.

Working Principle

The Spirometer Mouthpiece operates with a simple yet efficient logic. During lung function testing, the user bites down on the mouthpiece and holds the accompanying probe, creating a sealed space between the mouthpiece and the oral cavity. The sound waves emitted by the device vibrate stably within this sealed space. When these sound waves reach the lungs, they cause reflection, interference, and resonance.

By capturing and analyzing this feedback, the Spirometer Mouthpiece accurately derives key data such as lung volume and ventilation, providing doctors with a reliable basis for assessing lung health. Throughout the process, the mouthpiece's sealing performance directly affects the sound wave transmission, thus ensuring the accuracy of the test results.

Detailed Usage Instructions

To ensure smooth testing and precise results, follow these steps:

Pre-test Preparation: Ask the subject to rest for 5-10 minutes to relax and relieve tension, avoiding unstable breathing that may affect data accuracy;

Mouthpiece Installation: Take out the Spirometer Mouthpiece, place it in the subject’s oral cavity at a proper position to ensure a tight fit between the mouthpiece and lips. Firmly connect the other end of the mouthpiece to the pulmonary function testing device;

Device Calibration: After connection, the operator shall perform routine adjustments, inspections, and calibrations of all device parameters to ensure it is in normal working condition;

Test Execution: Start the testing program. The subject must bite the Spirometer Mouthpiece tightly and perform breathing operations strictly according to the device’s on-screen prompts or voice guidance. During the process, observe changes in on-screen data or indicator lights and cooperate to complete the test;

Data Confirmation: After the test, the device automatically records the data. The operator shall export and transmit the data to the host for verification to ensure completeness and accuracy;

Post-test Process: After the subject cleans their mouth, the operator determines whether a re-test is necessary based on the test data and doctor’s guidance.

Core Product Features

No Adapters Required: Designed to fit interfaces of mainstream pulmonary function testing devices, it supports plug-and-play use without additional adapters—saving operation time and reducing complexity;
