Flexible tube / Medical product

A wrist is free to move by bellows type of soft plastic.

The drip use is irritating because of restricted wrist movement caused by needles and catheters. In a serious case, a needle can impale the internal vessel through the skin.

Since this flexible plastic tube is a bellows type, it prevents such situations as impaling the internal vessel through the skin, needle disconnection and unintended taping detachment.
