Abstract
An anaesthetic medical facemask includes a disposable air cushion and a reusable shell attached to the air cushion. The air cushion is made of thermoplastic urethane elastomer (TPU). TPU is a hydrolysis material so that the TPU can decompose in a short time. The air cushion is thrown away and does not pollute the environment after use. The shell can be with another patient after disinfecting the shell because the shell never comes in direct contact with the patient during use. Consequently, the volume of the medical waste is smaller and the cost of environmental protection becomes lower.
