Optional cradles transfer data to PC for storage/analysis or printer for report generation. Provides objective lung function data to aid clinical decision-making and screening.

Clinical Evidence

Bench testing performed using ATS-compatible automatic waveform generators to validate measurement accuracy against ATS and National Lung Health Education Program standards. Measurement-quality features validated using specialized most-probable-error flow waveforms. Simulated primary-care setting study confirmed usability, human-factors, and effectiveness for intended users.

Technological Characteristics

Pneumotachometry (differential pressure) sensing. Components: disposable mouthpiece, reusable handle with sensors, A/D converter, embedded microprocessor, LCD display, IR port.

Indications for Use

Indicated for use in primary-care settings to measure and report PEF, FEV1, FEV6, FEF25-75%, and FEV1/FEV6 ratio for diagnostic and screening purposes in patients requiring lung health assessment.

Regulatory Classification

Identification

# Device Description

KoKoMate is a hand-held, self-contained spirometer 31 with disposable mouthpiece designed specifically to measure a few simple expiratory spirometry values in the primary-care setting for diagnostic and screening purposes. The meter features a 4-line by 16-character LCD display; four control buttons; a port to accept its mouthpiece/flow-tube; and an IR data-transfer port.

The device measures expiratory breath flow through its mouthpiece, which is designed for single use. For a maximal expiratory effort, the meter determines peak expiratory flow (PEF), one-second forced expiratory volume (FEV1), six-second forced expiratory volume (FEV6), and average forced expiratory flow from 25 - 75% of total volume (FEF25-75%). It reports these values plus the ratio of FEV1/FEV6 and an indication of how these values compare to recognized predicted values. In addition, the meter processes the signals from each expiratory

maneuver to help determine the quality of the maneuver to aid the clinician or patient in determining whether the reported values are valid.

Along with the spirometer, the KoKoMate system can include one of two optional accessory products. These accessories act as data transfer conduits transferring data streams across optic and serial interfaces as they cradle the meter. One cradle is designed to couple the meter to a PC for data storage, printout, or analysis; the other links the meter directly to a printer for direct printout of a simple spirometry report.

#### Indications for Use

KoKoMate is a diagnostic spirometer for use in the primary-care setting to measure and report the following spirometric values: Peak Expiratory Flow (PEF), One-Second (FEV1) and Six-Second (FEV6) Forced Expiratory Volumes, Forced Expiratory Flow averaged from 25 - 75% of total volume (FEF25-75%), and the ratio of FEV1/FEV6.

### Summary of Technological Characteristics

The KoKoMate measures flow by pneumotachometry (using differential pressure across a known restriction to indicate air flow). The flow path in the meter is a single-use element mounted in pneumatic communication with a durable, reusable handle contains . sensors and associated electronics for interpretation, storage, display, and communication of flow data and test results. The handle houses the battery, pneumatic sensor, analog-to-digital converter, embedded microprocessor, control buttons, multiple-line alphanumeric display, and infrared data port.

Data communication between the meter and a PC or printer may be made through IR data ports on the meter and in one of the optional data-transfer accessories. Data transfer, storage, and display on a PC is done with an existing Windows-based spirometry program available from PDS. Control firmware embedded in the Printer/PC Cradle allows direct printing of the data stored in the meter in a simple report format.

# Summary of Non-Clinical Performance Data

# Safety

KoKoMate units were examined and bench tested by third-party examiners to demonstrate conformance to two recognized international consensus standards for safety of medical electrical equipment. The standards are EN 60601-1:1988 with amendments for general safety and EN 60601-1-2:1993 for electromagnetic compatibility.

#### Effectiveness

In-house and third-party testing, using an ATS-compatible automatic waveform generator. demonstrated that the measurement performance of the spirometer met or exceeded requirements published in the National Lung Health Education Program's consensus statement for office spirometry11 and in the American Thoracic Society's standard for diagnostic spirometry [2].

Meter function was also tested using specialized most-probable-error flow waveforms to validate measurement-quality features. The measurement-quality study demonstrated that the KoKoMate can appropriately provide information regarding a subject's PEF, FEV1, FEV6, FEF25-75%, and FEV1/FEV6 measurements and can identify measurements of suspect quality appropriately.

# Summary of Clinical Performance Data

Testing in a simulated primary-care setting demonstrated that patients and clinicians in that environment can safely and effectively use the KoKoMate under conditions of actual use and that the users guide, product physical design, and other human-factor characteristics of the KoKoMate system are appropriate for the product's intended use.

# Equivalence to Predicate Devices

The KoKoMate's design is a direct design enhancement of the AccuTrax predicate: using the same technologies, design principles, and manufacturing approach; but extending its features and accuracy. The system is substantially equivalent to the Spirovit SP-2: using the same measurement principles; using similar construction, material, and energy source; and meeting the same performance characteristics. The differences are that KoKoMate has a simpler user interface and reports a reduced set of spirometry values compared to the Spirovit.
