Nasopharyngeal Sample and Buffer System with Lateral Flow Cartridge

Our Role

  • Design a lateral flow cartridge that integrates with a custom reader.
  • Design a nasopharyngeal sample and buffer system for use with lateral flow cartridge.


  • IVD
  • Point of Care
  • Diagnostic Equipment


Becton Dickinson and Company (BD)

Features & Accomplishments

  • Incorporated industrial design to meet requirements for ergonomics and brand conformance.
  • Optimized performance of lateral flow test strips through mechanical design that prevented sample leaks, occlusion of flow, strip movement and any other interference with assay.
  • Designed a sample collection and buffer mixing tube, cap and dispensing tip.
  • Fast tracked the project, completing the product design and transferring it to manufacturing, within the 4 month deadline.
  • Required extensive use of our stereolithography (SLA) machine in order to create multiple small, highly accurate, design iterations necessary to develop the lateral flow cartridge.  Our in-house rapid prototyping capability enabled us to achieve the aggressive development schedule.
