Portable Digital Bluetooth Spirometer

Introduction

The SPIROMETER is a hand-held equipment for checking lung conditions, adopts the infrared signal acquisition mode for measuring items related to FVC, and it is applicable for hospital, clinic, family for routine test.

Functions

• Forced Vital Capacity (FVC), forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC), peak expiratory flow (PEF), forced expiratory flow at 25% of FVC (FEF25), forced expiratory flow at 50% of FVC (FEF50), forced expiratory flow at 75% of FVC (FEF75), and forced expiratory flow from 25%-75% of FVC (FEF25-75) can be measured.
• The personnel information (including height, age, sex, etc.) can be input.
• Flow-volume chart, volume-time chart display.
• The data can be stored, deleted, uploaded, and reviewed.
• Trend chart display.
• Health state indication.
• Calibration function.
• Over-limit prompt function for volume and flow.
• Indicate expiration within 6 seconds by indicators.
• Start measuring by one-button.
• The data can be transmitted by Bluetooth or USB cable.
• Real-time clock can be set and displayed.
• Battery power indication.
• Automatic shutdown when there is no operation within two minutes.

Frequently Asked Questions

1. What additional product capabilities does this spirometer offer bulk buyers already selling basic peak flow meters?

Basic peak flow meters primarily provide peak expiratory flow (PEF) readings, while this portable spirometer also supports FVC, FEV1/FVC, FEF25, FEF50, FEF75, and FEF25–75, along with flow-volume and volume-time curves. Bulk buyers can position it as a more comprehensive portable lung function testing device, creating a distinct product category alongside basic peak flow meters rather than adding another model with similar functionality.

2. Does the Bluetooth version require a wireless connection for transferring test records?

No. The spirometer supports both Bluetooth and USB data transfer, with a USB cable and PC software included in the standard package. For procurement projects that rely on computer-based record management, the wired connection provides an alternative to Bluetooth. The device also supports storing, reviewing, deleting, and uploading test records, allowing bulk buyers to offer both wired and wireless data-transfer options.

3. Does the spirometer require an external display to show lung function curves?

No. The device features a built-in 2.8-inch color LCD screen that displays flow-volume curves, volume-time curves, and trend graphs. These visualization functions are integrated into the spirometer itself. For institutional purchasing projects requiring on-device graphical displays, bulk buyers can include these capabilities in the standard product specifications without presenting an external computer as a requirement for viewing lung function data.

4. Which built-in features help standardize testing procedures across bulk deployments?

The spirometer includes a calibration function, volume and flow limit alerts, a 6-second exhalation indicator, and one-button measurement activation. These features provide a consistent functional configuration for bulk buyers supplying the same model to multiple institutions. The 6-second indicator provides guidance during exhalation, but should not be described as automatic verification of every acceptable or unacceptable breathing maneuver.

5. How should disposable mouthpieces and nose clips be specified in bulk purchasing orders?

The standard package includes one disposable mouthpiece, while the nose clip is an optional accessory. Bulk buyers should separate meter quantities from replacement mouthpiece quantities when preparing bulk quotations and replenishment plans. For orders requiring nose clips, these can be listed separately in the accessory configuration. This distinction keeps equipment, disposable consumables, and optional accessories clearly identified in purchasing contracts.

6. What power configuration advantages does this rechargeable spirometer offer for mobile screening equipment procurement?

The device weighs approximately 190 g, measures 160 × 65 × 45 mm, and uses a rechargeable 3.7 V, 2200 mAh lithium battery rated for at least 300 charging cycles. Its built-in battery provides greater flexibility for mobile deployments compared with equipment requiring continuous external power. A USB cable is included in the standard package, while the power adapter is optional, allowing bulk buyers to differentiate between standard and adapter-inclusive configurations.
