Tongue depressor

Abstract

A tongue depressor for facilitating the placement of a laryngeal mask is disclosed. The tongue depressor includes a flexible main body; the flexible main body is long and flat with a width W and a thickness D, wherein 1.5 cm<W<3.5 cm and 0.05 mm<D<2 mm. The flexible main body has a bent state and a straight state. With the above structure, when the flexible main body is put into the oral cavity of the human body in the straight state, an external force is applied to the flexible main body and then the flexible main body transitions from the straight state to the bent state such that the flexible main body depresses the tongue base to form a channel with the upper jaw of the human oral cavity, through which the laryngeal mask can enter the human pharynx.
