Abstract
A tubular member 2 is formed of a resin material so as to have an inner passageway 2. A thin plate is shaped into a spiral along the perimeter of the tubular member 2 to form a reinforcement member 3. The reinforcement member 3 is buried in a peripheral wall 2a of the tubular member 2. The tubular member 2 and the reinforcement member 3 have curved shapes conformable to the shape of the pharynx 100. The tubular member 2 and the reinforcement member 3 are inserted from the oral cavity 102 into the pharynx 100 and retained there. A medical instrument is guided to the esophagus 103 through an inner passageway 2b of the tubular member 2.

A supporting device for supporting insertion of a medical instrument into a human body, comprising:
- a tubular member having an inner passageway between its opposite ends through which the medical instrument is capable of passing;
- and
- a reinforcement member formed by a thin plate extending along a perimeter of the inner passageway,
- wherein the tubular member and the reinforcement element have curved shapes conformable to the shape of a pharynx of a human body and, when inserted from an oral cavity into the pharynx and retained there, guide the medical instrument to a digestive organ through the inner passageway.
A supporting device for supporting insertion of a medical instrument into a human body, comprising:
- a tubular member having an inner passageway between its opposite ends through which the medical instrument is capable of passing;
- a reinforcement member extending along a perimeter of the inner passageway;
- and
- a guiding member having a diameter smaller than the inner passageway and insertable from an oral cavity of a human body into a pharynx, the guiding member guiding, when inserted into the pharynx, the tubular member and the reinforcement member from the oral cavity to the pharynx,
- wherein, when guided to the pharynx and retained there, the tubular member and the reinforcement member guide the medical instrument to a digestive organ through the inner passageway.
