I believe everyone has had this experience: when we go for an intravenous drip, the nurse will stick it on the back of our hand Medical Tape 。 The medical tape here is used to protect the drip needle from injuring the hands. There are other situations, in short, medical tape can effectively adhere medical equipment to the skin. However, when removed, it can feel very painful and in severe cases, it can cause skin tissue tearing and other problems.

&Nbsp;

In response to this issue, a hospital in the United States has invented a fast release device Medical Tape ， It has strong adhesion, but it does not cause pain during tearing, and can greatly reduce skin damage to patients such as newborns.

&Nbsp;

According to statistics, there are approximately 1.5 million injuries caused by inadequate removal of medical tape in the United States each year, most of which occur in infants and elderly populations with fragile skin.

&Nbsp;

Although the tape currently used, including backing and adhesive layers, will not have a significant impact on adults, for groups such as newborns, this type of tape can easily cause serious damage to their delicate skin and even form long-lasting scars.

&Nbsp;

Therefore, the research team added an anisotropic adhesive between the backing and adhesive layers, which means that this intermediate layer will exhibit different physical properties according to direction. For example, bonding along the texture of wood is better than bonding with cross textures.

&Nbsp;

Researchers have utilized laser etching and anti adhesive lining to create an anisotropic interface, allowing the new tape to have higher shear strength and lower peel strength. This allows for complete avoidance of skin damage during tape removal without affecting the adhesive strength of the tape. And removing the remaining adhesive from the backing can also be easily removed by rubbing with fingers, which can be said to be a blessing for patients such as newborns.
