Translated fromChinese技术领域technical field
本发明涉及医疗器械领域，具体涉及气道开放装置。The invention relates to the field of medical equipment, in particular to an airway opening device.
背景技术Background technique
创伤所致的可疑颈椎损伤，需要同时保护颈椎，即给予颈部制动，同时还需要开放气道，保持气道通畅。传统针对于创伤所致的可疑颈椎损伤，需要医务工作者采用手法开放气道，根据气道的解剖结构，使患者头部充分后仰，一手的食指与中指置于下颌处，使得下颌外露，与上颌错位，呈地包天形态(反颌形态)，使气道通畅。然后，开放气道需要医务工作者始终托住患者的下颌，操作较为繁琐，且无法始终保持角度和恒定用力。For suspected cervical spine injuries caused by trauma, the cervical spine needs to be protected at the same time, that is, the neck should be immobilized, and the airway should also be opened to keep the airway unobstructed. Traditionally, for suspicious cervical spine injuries caused by trauma, medical workers need to open the airway by manipulation. According to the anatomical structure of the airway, the patient's head is fully tilted back, and the index finger and middle finger of one hand are placed on the lower jaw to expose the lower jaw. It is misaligned with the upper jaw, showing a ground-covered shape (underbite shape), which makes the airway unobstructed. Then, opening the airway requires medical workers to always support the patient's jaw, which is cumbersome to operate, and cannot always maintain the angle and constant force.
针对上述问题，已存有辅助医务工作者的气道开放装置，比如公开号为CN204840573U公开了开放气道用颈托，再比如公开号为CN105963053A的一种气道开放辅助器。In view of the above problems, there are existing airway opening devices for assisting medical workers.
