Breath-enhanced two-way valve system allows inhalation of aerosolized medication. Used in hospitals, nursing homes, sub-acute institutions, and homes. Operated by patients or caregivers. Output: aerosolized medication for inhalation. Provides optical/acoustical feedback on status and errors. Benefits: efficient delivery of prescribed respiratory medication. No pause function, breath trigger, or interrupter; continuous nebulization until reservoir empty or Tmax reached.

Clinical Evidence

Bench testing only. Aerosol characterization (next generation impaction) showed MMAD, GSD, RF, and RD comparable to predicate. Biocompatibility (ISO 10993-1), gas path analysis, electrical safety (IEC 60601-1 series), EMC (IEC 60601-1-2), and simulated use (365 nebulizations/52 disinfection cycles) confirmed device performance and safety over one-year lifetime.

Technological Characteristics

Materials: polypropylene, thermoplastic elastomer, stainless steel, piezo-ceramic, polyamide film, medical adhesives. Principle: piezo-driven micro-perforated vibrating membrane. Energy: AC power or 3x AA batteries. Form factor: handheld, integrated controller/nebulizer. Connectivity: standalone. Sterilization: non-sterile. Software: moderate level of concern, embedded control logic.

Indications for Use

Indicated for adult and pediatric patients 4 years and older who can coordinate breathing through a mouthpiece, for whom doctors have prescribed medication for nebulization.

#### Device Description 4.

The Velox Nebulizer System is a portable, reusable, single-patient use, handheld electronic nebulizer that uses a piezo-driven, micro-perforated vibrating membrane technology to aerosolize liquid medications for the treatment or prophylaxis of respiratory diseases. It is to be used with adult and pediatric patients for whom doctors have prescribed medication, i.e. it is for prescription use only. It may be used in hospital-type facilities, nursing homes, sub-acute institutions and home environments. It is provided non-sterile.

The device consists of two major components. One of these components is the nebulizer itself, which has the following materials in its construction: (1) polypropylene: (2); thermoplastic elastomer; (3) stainless steel; (4) piezo-ceramic; (5) capton; and, (6) medical grade adhesives. It contains, as subcomponents, the following: (1) a medication cap, (2) a medication reservoir, (3) an aerosol head, (4) an aerosol chamber; and, (5) a mouthpiece.

The second major component is a Controller that is attached to the Nebulizer for its operation. This component, the body of which is constructed of acrylonitrile butadiene styrene and thermoplastic elastomer, has the following principal internal subcomponents: (1)

{4}------------------------------------------------

a circuit board: (2) a USB connector: (3) a patient interface (on/off switch); and (4) AA battery housing.

The controller's functions are to; (1) conduct power pre-processing; (2) supervise, through incorporated software, the nebulizer's aerosol generation; and, (3) generate optical and acoustical feedback to the user on nebulization status and out-of-range parameters.

The incorporated software is device-specific and: (1) controls the power to the aerosol head, i.e., either to have the aerosol head active and generate aerosol, or shut-off; (2) controls optical and acoustical feedback to the user; and; (3) is not dependent for its operation on any external devices, such as a monitor, printer, keyboard or mouse.

Energy sources for the device are provided by: (1) connection to a mains power source, via an AC Power Supply; or. (2) disposable/rechargeable AA batteries.

The device has two associated accessories: (1) a cleaning aid, branded VELOXcare, that assists in debris removal from the membrane prior to cleaning; and, as heretofore noted. (2) an AC Power Supply to provide mains power to the device when desired or required.

#### Mechanism of Action 5.

The Velox Nebulizer System's mode of action is permanent, i.e., once the on/off switch is on the controller pressed, permanent nebulization occurs until the medication is nebulized. There is no pause function. Further, there is no breath trigger or interrupter.

Nebulization is accomplished as follows. When the on/off button is pressed the controller sends an electrical charge to the aerosol head in the nebulizer. The charge alternation causes the piezo-actuator to vibrate. Vibration motion then builds up a positive pressure in the boundary layer of the liquid column, ejecting the fluid through the holes as droplets and creating the aerosol on the front side of the membrane. This aerosol is deposited vertically into the aerosol chamber. Once in the chamber it is available for inhalation by the patient.

The inhalation is via a breath-enhanced two-way valve system. During inhalation the inhalation valves open to allow fresh air to enter the aerosol chamber. This inhaled fresh air stream, takes the aerosolized medication, with minimum depositional loss, through the mouthpiece into the patient's respiratory tract. Note that, during inhalation, the exhalation valve on the mouthpiece is closed, preventing any aerosol dilution on its way to the patient. During exhalation, the inhalation valves close and the exhalation valve opens, driving the expired air out of the mouthpiece.

#### 6. Indications for Use

The Velox Nebulizer System is a handheld nebulizer that is to be used with patients for whom doctors have prescribed medication for nebulization. It is intended for adult and pediatric patients 4 years and older who can coordinate breathing through a mouthpiece, and may be used in hospitals, hospital-type facilities, nursing homes, sub-acute institutions and home environments.

The foregoing statement for the subject device is identical to that of the predicate eRapid® device (with the exception of the "4 years and older who can coordinate breathing through a mouthpiece" restriction. The indications are substantially equivalent; the subject device indication statement simply provides a quantification of patient age, and clarification of the patient's breathing

{5}------------------------------------------------

coordination ability at that age). Further, both the subject and predicate device have the same intended use.
