To reduce the size of the product, the wound seal is packed with a sterile 4″ x 4″ gauze pad. The sealing rectangle has the same polyurethane carrier and adhesive as the Bolin Chest Seal. The product is quarter-folded and vacuum sealed to fit in a space as thin as half an inch! The new redesigned seal comes with rounded edges to reduce friction with clothing. Also added, a new long tab to one end to allow for venting and easy removal and repositioning of the seal over the injury.
