Furthermore, in order to prepare both of these facilities, it was necessary to secure a sufficient place for installation, which was a considerable cost.

In order to solve such a problem, a pseudo head model that can be accommodated in a trunk container and can protrude outward from the trunk container has been proposed (see Patent Document 1).
The pseudo head model described in Patent Document 1 can be fixed to a medical examination table by using the trunk container as a patient's torso in a state where the pseudo head model projects outward from the trunk container. Therefore, it is said that a realistic state close to that of actual medical care can be reproduced and a sufficient effect can be obtained as practical training.

  However, if it is difficult to handle the pseudo head model in a trunk container, or the pseudo head model is taken out of the trunk container and fixed to a medical examination table, or if it is not used for practical training, Since the trunk container containing the pseudo head model was stored, the storage place was bulky, so the convenience was low and it was not satisfactory.
