SmartDose uses a unique microprocessor and pressure transducer to monitor oxygen requirements for every breath. Sophisticated algorithms instruct the multi-valve mechanism to deliver the oxygen dose required by the user at any activity level. Fixed-dose devices, on the other hand, are indiscriminate, and lack the technology necessary to monitor user requirements or automatically adjust dosing. Most often, other devices deliver too little oxygen during activity and too much during rest. On fixed- dose devices, patients experience far more frequent incidences of breathlessness. SmartDose also provides information to clinicians and dealers about usage patterns, breath rates, and activity. Microprocessor data is captured to an on-board SD Card that can be removed and reviewed on any personal computer. This data is invaluable in providing a clearer understanding of how the unit is being used, and aiding the patient in maximizing the benefits and freedom their portable can offer. SmartDose is available for both liquid and gas cylinder applications. Because SmartDose better maintains oxygen saturation, the user is better able to participate in conditioning exercises. This decreased work of breathing not only improves their quality of life, it reduces stress on the organs, and ultimately increases longevity. SmartDose takes your patient's mind off their device so they can focus on what really matters; living with COPD, with the emphasis on living. SiGenix developed the electronics and embedded software for the SmartDose devices. All electronics design, circuit board layout, and prototype assembly were performed by SiGenix. The units feature an SD Card interface used for firmware upgrades and data logging.
A follow-on unit was designed by SiGenix that incorporated hardware and software changes to create an extremely low power device that extend battery life for the patients by 2 orders of magnitude.
