A new 3D-printed Covid-19 testing swab which can collect sufficient viral material from the back of the nose – without need of a throat swab – is now being manufactured in Scotland.
The nasopharynx 3D printed swabs provide a less intrusive experience compared to traditional cotton bud swabs, cutting testing time, reducing anxiety and minimising discomfort for patients.
The Medical Device Manufacturing Centre (MDMC), based at Heriot-Watt University, and the Scottish Manufacturing Advisory Service (SMAS) at Scottish Enterprise have worked with Scottish company Abergower 3D, to manufacture the new design.
Once used, the swabs can be processed at labs like Lighthouse in Glasgow.
The unique helix designed tip of the swab guarantee that sufficient material is collected to provide a definitive result.
The unique configuration of the tip allows capillary retention of the liquid as well as preventing the liquid from escaping the tip. The amount of viral load is further increased because the swab is non-absorbent unlike most cotton varieties.
