A bullet plug gunshot wound first aid device (BulletPLUG) that can be scaled in size to insert into a bullet wound, transform from a rolled cylinder of durable flexible clear material into an expanding tunnel of clear unrolled material to open the hole from a bullet wound to expose the bullet's location at the end of the tunnel and provide a clear, light illuminated, open tunnel to facilitate removal of the bullet, while a local coagulant coating on the outside surface of the tunnel stops the bleeding of the bullet wound into the bullet hole, while a powerful local anesthetic reduces the pain of the wound. The current invention also provides an Open Operation (OpenO) device that spreads open an incision to aid in a surgical operation by providing a clear, light illuminated, open tunnel to facilitate sub-dermal access, while a local coagulant coating on the outside surface of the tunnel reduces the bleeding of the incision, while a local anesthetic reduces the pain of the incision.
