The subject device has same intended use, same target patient population, same performance effectiveness, performance safety as the predicate devices and no question is raised regarding to effectiveness and safety. So, the conclusion is that the subject device is substantial equivalent to the predicate. #### 5. Intended use & Indication for use GUS831 compressor nebulizer is designed for the production of compressed air to operate a nebulizer kit for the production of medical aerosol for respiratory disorders. The nebulizer kit is intended for multiple use by single patient for single medication. GUS831 compressor nebulizer is intended for domestic use with children from 5 years old, adolescent and adult patients and requires the order of a physician for medical use. #### Device Description 6. GUS831 Compressor Nebulizer is a portable aerosol nebulizer electronically powered by an external power {4}------------------------------------------------ adapter and by an internal rechargeable lithium polymer battery. The compressed air, created by the membrane pump of the device, flows into the nebulizer container kit. The air pressure forced the liquid through the nozzle where it is atomized against a plate within the container. The device is equipped with a mouthpiece to easily delivery the medical aerosol. #### 7. Principle of Operation This device operates on the Venturi principle. Compressed air is driven through a converging nozzle, where it accelerates and emerges at a high velocity, creating a vacuum (Venturi effect). The vacuum draws a liquid residing in a reservoir up through a cylindrical channel and into the emerging airstream formed by the nozzle, to mix with air and impact upon a rigid surface. This process uses energy from the airstream to convert liquid into small droplets called aerosol. Upon reaching the user aerosol is suitably refined to enter the lungs effectively. #### Comparison to the Predicate Device 8. The GUS831 Compressor Nebulizer and U-RIGHT Compressor Nebulizer (K121969), are identical in purpose, function, core technology and method of operation. Only minor differences exist between the GUS831 Compressor Nebulizer and predicate, which do not affect the safety or effectiveness of the subject device. Table 1 provides a comparison of the subject and predicate devices. | Features | Subject Device GUS831 Compressor Nebulizer | Predicate Device U-RIGHT Compressor Nebulizer | Comment | |-------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------| | K number | K192633 | K121969 | / | | Indication for use | GUS831 compressor nebulizer is designed for the production of compressed air to operate a nebulizer kit for the production of medical aerosol for respiratory disorders.
