• Attributes: Pediatric

Intended Use

The Microlab spirometer is intended, for prescription use only, to measure the maximal volume and flow of air that can be moved in and out of a patient's lungs. The system is intended for use with pediatric (4 to 17 years) and adult (18 to 99 years) patients in hospitals, physician offices, laboratories and occupational health testing environments.

Device Story

Microlab Spirometer measures lung function via digital volume transducer; turbine sensor captures airflow; electronic integration converts flow to volume; system calculates clinically relevant parameters; compares results to published predicted normal values. Used in hospitals, physician offices, laboratories, and occupational health settings by clinicians. Output displayed for provider assessment of lung disease detection and monitoring.

Clinical Evidence

Bench testing only. Performance testing conducted to demonstrate compliance with American Thoracic Society accuracy and precision standards. Electrical safety testing performed per IEC60601-1-2.

Technological Characteristics

Turbine sensor for airflow measurement; electronic integration for volume calculation. Includes digital volume transducer, housing, AC power adapter, and disposable cardboard mouthpieces. Connectivity via serial cable for external printer. Electrical safety per IEC60601-1-2.

Indications for Use

Indicated for pediatric (4-17 years) and adult (18-99 years) patients for measuring maximal volume and flow of air in/out of lungs to detect and monitor lung diseases. Prescription use only.

Regulatory Classification

Identification

A diagnostic spirometer is a device used in pulmonary function testing to measure the volume of gas moving in or out of a patient's lungs.

Device description: The Microlab spirometry systems consists of the Microlab spirometer, digital volume transducer, transducer housing, AC power adapter, power supply cord, disposable cardboard mouthpieces, carrying case, quick start guide and operators manual. Optional accessories include calibration syringe, nose clips, serial cable and a serial to parallel converter for use of an external compatible printer.

Intended use: The Microlab spirometry system is intended, for prescription use only, to measure the maximal volume and flow of air that can be moved in and out of a patient's lungs. The testing can be used in the detection and monitoring of certain lung diseases. The system is intended for use with pediatric and adult patients (4 to 99 years old) in hospitals, physician offices, laboratories and occupational health testing environments.

Comparison to predicate device: The Microlab spirometry system has the same technological characteristics of the referenced predicate device. In both devices, air flow is measured directly via a turbine sensor and then electronically integrated to obtain volume. Both devices then perform calculations to express the volume in clinically relevant terms, including comparisons to predicted normal values from published literature. The intended use for both devices is the same.

Summary of Testing: Performance testing was conducted to demonstrate compliance with the accuracy and precision standards set by the American Thoracic Society.

The device was tested to demonstrate conformance with IEC60601-1-2 requirements for electrical safety.

- Conclusion: The Microlab spirometry systems does not raise new questions of safety or effectiveness when compared to the legally marketed predicate device and is substantially equivalent to the predicate device.

Dear Mr. Staszak:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
