Problem
Traditional nasopharyngeal swabs for respiratory specimen collection can be invasive, painful, and prone to collection errors, leading to patient discomfort and potentially inaccurate results. This can result in delayed or avoided testing, hindering effective management of respiratory infections.
Solution
MicroWash is a nasal lavage specimen collection device designed to improve the accuracy and comfort of respiratory sample collection. The device uses a nasal irrigation method to collect samples from deep within the nasal cavity, yielding higher sensitivity compared to traditional swabs. The design facilitates ease of use and self-administration, while also boasting a longer shelf life than standard nasal swab kits. By providing a more comfortable and reliable collection method, MicroWash aims to increase testing rates and improve overall infectious disease management.
