Allow us to walk you through some of the features and benefits of our Pre-filled Nebulizer System (PFN™). The following device illustrations you see on this page are artist renderings of the founder’s vision a pre-filled nebulizer. While these renderings are merely conceptual, they serve as a visual aid to illustrate the functionality of the PFN™ in concert with the Therapy ‘T’ as a complete device.
Whether assimilating protected elements of the PFN™ into a totally new device s depicted below, or adapting these elements to fit on an existing device, the patents in Caddo’s IP portfolio allow for a highly differentiated and innovative approach to packaging and delivering aerosolized medication.
Caddo’s PFN™ ‐ A Complete Pre-filled Nebulizer System
- Pre-filled & Sterile – Single, Precise Dose of Medication
- Fully-Assembled – Labor-Efficient, Easy-to-Use
- Single‐use – One Therapy & Discard
- Proprietary Breath‐Enhanced Therapy ‘T’
- Two Therapies in One (PEP and Aerosol)
- Innovative Packaging ‐ Color‐coded, Clear Labeling


Ready to use with a quarter turn of the Breath‐enhanced Therapy ‘T’
The Caddo’s PFN™ is activated by a quarter turn of its proprietary ‘T’, thereby breaking the hermetic seal (shaded in red) and readying the PFN™ for the treatment.
The one way valve (shaded in green) is breath-activated to minimize loss/waste of medication during exhalation reducing discharge of aerosolized medicine into the treatment area.
The CADDO PFN™ is Clearly a Better Way
Legacy Nebulizer Technology
& Treatment Protocol
- Contamination-prone (nearly every step)
- Labor/time-intensive (21 steps ≈ 30 mins)
- Inconvenient for clinicians
- Inconvenient for self-treatment at home (particularly for the elderly and pediatric patients)
- Subject to misdosing errors, risks and liability
- Subject to medication spills and waste
- Nearly impossible to effectively clean to sterile state
Caddo’s PFN™ Technology
& Treatment Protocol
- A sterile nebulizer for every treatment
- Labor/time-efficient (7 steps ≈ 10 mins)
- Convenient for clinicians
- More convenient for self-treatment at home (particularly for elderly and pediatric patients)
- Decreases misdosing errors, risks and liability
- Eliminates medication spills and waste
- No cleaning necessary – use and discard

Efficient Medication Delivery
The one-way, breath-activated valve prevents loss of medication during exhalation mitigating medication waste and discharge of aerosolized medicine into the treatment room, while the bi-directional Flow Control Valve provides lung exercise therapy in the form of Positive Expiratory Pressure (PEP) and optimizes flow for optimum deposition of aerosolized medication into the lungs.

Clear labeling, Color‐coded Peel Pack
The Caddo PFN™ comes pre-filled with a sterile, single dose of the exact amount of the proper medication. The envisioned easy peel, see-through packaging would allow clear, color-coded labels incorporating large fonts for easy dosage identification.
