Intended Use

The Flowhandy ZAN100 USB is an open, personal-computer-based spirometry system with optional shutter for measuring and analyzing breath flow, volume, and pressure in adult and pediatric subjects for use by pulmonologists, allergists, general practitioners, and occupationalmedicine practitioners in lung-function diagnosis.

Device Story

Flowhandy ZAN100 USB is a PC-based pneumotachometer spirometry system. Input: breath flow/pressure via hand-held pneumotach with variable-orifice core and differential pressure sensor. Optional solenoid-activated shutter interrupts airflow for pressure measurements. Transformation: PC software calculates spirometric values from pressure drop across orifice. Output: spirometric data displayed, stored, and analyzed on PC. Used in clinical settings (pulmonology, allergy, general/occupational practice) by healthcare professionals. Benefits: enables lung-function diagnosis through standardized breathing maneuvers.

Clinical Evidence

No clinical trials were conducted. Evidence consists of bench testing for safety (EN 60601-1, EN 60601-1-2) and effectiveness (meeting American Thoracic Society requirements). Clinical performance is supported by CE marking and historical operational data in Europe demonstrating safe and effective use under actual conditions.

Technological Characteristics

Pneumotachometer using variable-orifice diaphragm; semiconductor pressure transducers (0-1.4 kPa flow, 0-7 kPa pressure). Materials: POM (polyoxymethylene). Power: 5 VDC via USB. Dimensions: 100x90x45 mm. Connectivity: USB interface to PC. Applied part: Type BF. Enclosure: IPX1. Software-based analysis of flow/volume/pressure.

Indications for Use

Indicated for adult and pediatric patients requiring lung-function diagnosis, including measurement and analysis of breath flow, volume, and pressure.

Regulatory Classification

Identification

#### Device Description

The Flowhandy ZAN100 USB is a pneumotachometer spirometry system. The system comprises a Windows personal computer (sold separately) for data collection, analysis, storage, and display; proprietary Betterflow ZAN100 USB software program for the PC; and a Flowlandy, hand-held pneumotach with reusable variable-orifice core, differential pneumatic pressure sensor, and USB interface. An optional computer-controlled shutter may be added to the air passageway to interrupt flow to allow pressure measurements using the on-board pressure sensor.

The ZAN100 measures the pressure drop across the known orifice to indicate the rate of breath flow both in and out of the air passageway. Knowing the flow rate of air from a subject allows the calculation of the most recognized spirometric values for the subject. Closing off the passageway with the optional shutter enables the pressure sensor to take important pressure measurements for the subject's breathing as well.

#### Indications for Use

The Flowhandy ZAN100 USB is an open, personal-computer-based spirometry system with optional shutter for measuring and analyzing breath flow, volume, and pressure in adult and pediatric subjects for use by pulmonologists, allergists, general practitioners, and occupationalmedicine practitioners in lung-function diagnosis.

{1}------------------------------------------------

## Summary of Technological Characteristics

The Flowhandy uses the pressure difference in the air stream across a variable-orifice diaphragm to measure a subject's airflow rate (pneumotachometry) throughout established breathing maneuvers to provide spirometric analysis. The instantaneous flow rate values are acquired on a personal computer, where the data is analyzed, stored, and displayed. The optional shutter is a solenoid-activated valve for interrupting airflow.

## Summary of Non-Clinical Performance Data

#### Safety

.

The Flowhandy was examined and bench tested by third-party examiners to demonstrate conformance to three recognized international consensus standards for safety of medical electrical equipment: EN 60601-1 for general medical-device safety of medical electrical safety, and EN 60601-1-2 for electromagnetic compairity,

#### Effectiveness

ln-house and third-party testing demonstrate that Flowhandy measurement performance meets or exceeded published American Thoracic Society requirements and the claimed performance meeting requirements under stated and anticipated operating conditions.

{2}------------------------------------------------

## Summary of Clinical Performance Data

CE marking and years of successful operation in Europe demonstrate that patients and clinicians can safely and effectively use the Flowhandy under actual-use conditions and that the users guide, product physical design, and other human-factor characteristics of the Flowlandy system are appropriate for the product's intended use.

## Equivalence to Predicate Devices

The Flowhandy design uses the same technologies and design principles as its predicate devices. The system is substantially equivalent to Jaeger's MasterScreen Pneumo: using the same measurement principles; similar construction, material, and energy source; and meeting the same performance characteristics and intended uses.
