Nebulizer Add-Ons: Innovative Features for Improved Respiratory Therapy

Asthma, a common respiratory condition that affects people all over the world, presents significant challenges that demand effective treatment. While nebulizers have become essential tools in respiratory therapy, there is still a need to increase their efficiency and effectiveness, particularly in considering certain challenges experienced by asthma patients. To address these asthma-related difficulties comprehensively, introducing innovative features to enhance nebulizer functionality. the inclusion of a meticulously developed 3D-printed return valve, precisely designed to stop medication backflow, hence decreasing pharmaceutical waste, and providing patients with better care at lower costs. Additionally, redefining the patient's experience by integrating color sensor within the nebulizer's filter, which will give a visual cue for rapid filter color change. This improvement should reduce problems caused by improper filter use and guarantee dependable, constant filtration for those with asthma. The addition of a flow sensor to the nebulizer will improve the accuracy of drug delivery for people with asthma by monitoring and controlling the medication administration process. On implementing this system for 25 subjects, inferred that the breathing flow rate is very useful in determining drug usage. Further, using the return valve ensures maximum drug delivery. To maintain hygiene and prevent microbial activity, the Heat and Moisture Exchanger (HME) filter with a wetness Indicator was found very useful in all the subjects after a trial duration of 8 hours on non-drug testing.
