Abstract: A medical simulator includes: a luminal organ model having flexibility and having a shape that simulates at least one luminal organ, the luminal organ model including a constricted wall portion having a lumen cross-sectional area smaller than the lumen cross-sectional area of a periphery of the constricted wall portion, the constricted wall portion being provided in a first specific region including a portion corresponding to one end portion of one luminal organ or corresponding to a joining portion of two luminal organs; a first space formation portion that circumferentially covers at least an outer periphery of the first specific region of the luminal organ model to form a first sealed space at the outer periphery of the first specific region; and a fluid controller that controls a fluid pressure of a to-be-controlled fluid within the first sealed space to expand or contract the lumen cross-sectional area of the constricted wall portion of the luminal organ model.

Abstract: A medical simulator allows a training of a medical procedure performed at least from a nose or a mouth, and includes a skeleton base portion that serves as a base of a shape of a human body at least from a head to a neck portion and an in-body forming portion that is attachable to and detachable from the skeleton base portion and has a shape that simulates a hollow in-body organ including a nasal cavity, an oral cavity, a pharynx, and a larynx, the in-body forming portion being integrally formed using a flexible material.

Abstract: A medical simulator has a human body model that simulates a human-body external shape at least from a head to a neck, an oral cavity portion, a nasal cavity portion, a pharynx portion, a larynx portion, a trachea portion, and an esophagus portion, thereby enabling at least training of an intubation procedure to be done. The medical simulator includes: a neck supporting portion that serves as a framework of the neck of the human body model and is provided so as to extend to the head; and a simulated thyroid cartilage portion that is connected by a first spring member to the neck supporting portion and is disposed in the larynx portion of the human body model.
