Abstract
A mouth speculum allows an intubation tube to pass through a patient's mouth in a stable condition, while offering comfort in its use. Two lip-pressing pieces curve outwardly at the left and right sides in such a manner as to become smoother toward the center in the vertical direction, and have external surfaces depressed inwardly in the left-right direction; and a handle curves upwardly or downwardly and is joined under the condition of exerting bending elasticity with respect to the two lip-pressing pieces. At least one of the two lip-pressing pieces includes a concave cut and/or a hole, to allow the intubation tube to pass through it at the front-side piece and the rear-side piece which are depressed outside in the left-right direction.

A mouth speculum comprising:
- two lip-pressing pieces which curve outwardly at left and right sides thereof in such a manner as to become smoother toward a center thereof as viewed in a vertical direction thereof, and the two lip-pressing pieces have external surfaces which are depressed inwardly in a left-right direction;
- and
- a handle which curves one of upwardly and downwardly, and which is joined under a condition of exerting bending elasticity with the two lip-pressing pieces,
- at least one of the two lip-pressing pieces including a concave cut at a front-side piece and a rear-side piece thereof to allow an intubation tube to pass through the concave cut at the front-side piece and the rear-side piece, with the front-side piece and the rear-side piece forming an outwardly facing depression in the left-right direction.

- two lip-pressing pieces which curve outwardly at left and right sides thereof in such a manner as to become smoother toward a center thereof as viewed in a vertical direction thereof, and the two lip-pressing pieces have external surfaces which are depressed inwardly in a left-right direction;
- and
- a handle which curves one of upwardly and downwardly, and which is joined under a condition of exerting bending elasticity with the two lip-pressing pieces,
- at least one of the two lip-pressing pieces including a hole at a front-side piece and a rear-side piece thereof to allow an intubation tube to pass through the holes at the front-side piece and the rear-side piece, with the front-side piece and the rear-side piece forming an outwardly facing depression in the left-right direction.
