 产品性能介绍说明

In medicine, a nasopharyngeal airway, also known as an NPA,nasal trumpet (because of its flared end), or nose hose, a type of airway adjunct, is a tube that is designed to be inserted into the nasal passageway to secure an open airway. When a patient becomes unconscious, the muscles in the jaw commonly relax and can allow the tongue to slide back and obstruct the airway. The purpose of the flared end is to prevent the device from becoming lost inside the patient's nose.
