Abstract
An airway is secured without obstructing sleep even when the lingual radix falls into the airway. An airway expansion apparatus is configured to include a pillow portion that supports a cranial portion, a pair of left and right mandible holding portions that hold the mandible coupled to the cranial portion at the temporomandibular joint, a first actuation mechanism that causes the mandible holding portions to come into contact with the mandible, and a second actuation mechanism that lifts the mandible holding portions with respect to the pillow portion with the mandible holding portions kept in contact with the mandible, in which the mandible is kept lifted.
Claims16
An airway expansion apparatus comprising:
- a pillow portion that supports a cranial portion;
- a pair of left and right mandible holding portions that hold a mandible coupled to the cranial portion at a temporomandibular joint;
- a first actuation mechanism that causes the mandible holding portions to come into contact with the mandible;
- and
- a second actuation mechanism that lifts the mandible holding portions with respect to the pillow portion with the mandible holding portions kept in contact with the mandible.
An airway expansion apparatus comprising:
- a pillow portion that supports a cranial portion;
- a pair of left and right mandible holding portions that hold a mandible coupled to the cranial portion at a temporomandibular joint;
- and
- a pair of left and right side plates in which slopes are formed so as to elevate from the mandible toward the parietal region in correspondence with the mandible holding portions,
- wherein the mandible holding portion comprises an abutting portion abutting on the slope, and
- the abutting portion moves the mandible holding portion in a direction perpendicular to the slope by abutting on the slope.
An airway expansion apparatus comprising:
- a mandible holding unit comprising a pair of mandible holding portions that hold a mandible coupled to a cranial portion at a temporomandibular joint and a coupling portion that couples the pair of mandible holding portions and keeps the mandible holding portions in contact with the mandible, and
- an actuator that supports the cranial portion, is attached to the mandible holding portions and lifts the mandible holding portions with respect to the cranium supporting portion with the mandible holding portions kept in contact with the mandible,
- wherein the actuator comprises a bag body whose interior can be filled with a fluid and the fluid filling the interior of the bag body can flow.
