NumoSeal™ · In development

Secures. Seals. Simplifies.

NumoSeal™ is designed to be the first device to both secure a chest tube and seal the insertion site, combining a high-adhesion patch with a proprietary sealing element.

How it works

A simple device, designed for any member of the care team

Three moments in the life of a chest tube, one device.

Illustration: NumoSeal sliding over a chest tube onto the skin

Placement

Slides over the tube, sticks to the skin and locks the tube in place.

Illustration: NumoSeal securing a chest tube at the insertion site

Dwell time

Secures the tube and protects the insertion site.

Illustration: chest tube being withdrawn through NumoSeal

Removal

Designed to seal the site automatically as the tube is withdrawn.

How NumoSeal™ works

From placement to removal: a compressive band, two zip ties, and a silicone valve that closes behind the tube. Drag to rotate; tap a dot to jump to a step.

Design goals

Securement and sealing, in one design

Who it’s for

Designed with patients, providers and hospitals in mind

  • Patients: designed to make chest tube securement more comfortable and to protect the insertion site.
  • Providers: designed to enable a standardized removal workflow and reduce time spent managing chest tubes.
  • Hospitals: a single-use consumable purchased through supply-chain budgets as part of inpatient care, with no new billing codes required.
