The Invention of the Modern Adhesive Bandage

A 1926 patent by Johnson and Johnson for the first mass-produced, sterile adhesive bandage, commonly known as the Band-Aid.

What it covers

This patent describes a surgical dressing consisting of a strip of adhesive material with a central, non-adhesive pad of sterile gauze. The design allows the user to apply a protective, absorbent covering to a minor wound without needing separate tape or pins. By integrating the adhesive backing and the sterile pad into a single, ready-to-use unit, it simplified the process of dressing small cuts and scrapes in a home environment.

What it doesn't cover

• —Does not cover non-adhesive bandages or traditional gauze rolls.
• —Does not cover liquid bandages or spray-on wound sealants.
• —Does not cover medical dressings that require separate adhesive tape for fixation.
• —Does not cover complex surgical sutures or internal wound closure devices.

The clever bit

The innovation was the pre-assembly of the sterile pad onto the adhesive strip, turning a multi-step medical procedure into a single, disposable consumer product.

Why it matters

This invention transformed home healthcare by making sterile wound care accessible to the general public. Before this, treating a minor cut required cutting gauze and applying separate adhesive strips, which was cumbersome and often non-sterile. It established the standard for the modern first-aid kit.
