KU students develop world’s smallest nebuliser

Final-year students from the Pharmacy Department at the University of Karachi have created the world’s smallest rechargeable nebuliser, designed to provide portable respiratory therapy for individuals with breathing difficulties.

The device, which measures less than one inch in width, offers up to 35 minutes of operation on a single charge, and the battery lasts for up to two days before needing a recharge.

The innovative nebuliser is made from eco-friendly bioplastics, making it an environmentally sustainable option.

Its compact design and quiet operation make it ideal for use in offices, while traveling, or in any setting where discreet and portable respiratory support is needed. The device features both micro-USB and USB-C charging options, allowing for easy recharging.

Group leader Abdul Rahman Siddiqui explained that traditional nebulisers on the market are often bulky, noisy, and priced between Rs 8,000 and Rs 10,000.

In contrast, their newly developed nebuliser is priced under Rs 2,000, making it an affordable alternative for a wider range of patients, including children and elderly individuals suffering from asthma or chest infections.

The team, consisting of Abdul Rahman Siddiqui, Taha Ishaq, Syed Waliuddin, Syeda Arshiya, Zohaib Salman, Maham Zaidi, Priyan Khan, and Tuba Saleem, hopes their creation will make respiratory therapy more accessible and provide an environmentally conscious solution to healthcare challenges in Pakistan.
