Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disposable speculum or vaginal speculum.

<Prior Art> Various speculums have been used for the observation and treatment of the vagina and utero-vaginal region, but these are made of chromium-treated metal and are repeatedly used after disinfection and sterilization. It's becoming like that. Therefore, if sterilization is not sufficient, there is a possibility of secondary infection. Furthermore, it requires autoclaves and other expensive equipment for sterilization.

<Problems to be Solved by the Invention> The purpose of the present invention is to provide a vaginal speculum that is made of flexible synthetic resin and is disposable once.

<Means for solving the problem> For this purpose, according to the present invention, a see-through part equipped with a through hole for observing the inside of the vagina, and an elongated insertion part for insertion into the vagina are provided. The insertion section is comprised of a pair of substantially semi-cylindrical members having an outwardly curved outer surface and a rounded tip, each member extending substantially parallel to the transparent section from the transparent section. A disposable vaginal speculum is provided, which is elongated and integrally molded with flexible synthetic resin so that the pair of insertion portions can expand in the vagina due to elasticity.

<Example> Vaginal mirror 1 for gynecology shown in Figs. 1 to 3
0 consists of a single member made of flexible material such as synthetic resin, and the vaginal speculum 10 has a see-through section 2 at the rear.
It is equipped with 0. This see-through part 20 has a see-through hole 21 in the center and a through hole 2 on its inner surface.
Two long reinforcing ridges 22, 22 are provided substantially parallel to each other along the upper and lower edges of 1.

This transparent portion 20 exhibiting a predetermined curvature has curved portions 2 on both sides thereof with a larger curvature than its own curvature.
3, and these curved portions have reinforcing protrusions 24, 24 whose overall length is considerably smaller than these protrusions 22, 22 so as to follow each of the protrusions 22.
is formed.

The curved portion 23 is formed so as to face inward, and is slightly smaller in height than the transparent portion 20 (see FIG. 3).

The curved portion 23 terminates at the starting ends of two long main body portions 30 facing each other, and the outer surface of each of these main bodies 30 is a curved surface with a constant curvature almost up to the terminal end side, At this terminal side, the tip 3 has a rounded shape of approximately half a circumference.
It has become 2.

The inner surface 31 of each main body 30 is a concave surface in the longitudinal direction corresponding to the curved surface, and this concave surface is
It is defined by an edge 33. A series of short length grooves 34 are cut into each edge of the concave inner surface of the body 30.

As explained above, according to the present invention, a disposable vaginal speculum integrally molded from synthetic resin is obtained, which is not only convenient to use, but also includes a transparent part on the rear side of the speculum and, if necessary, Reinforcing protrusions are formed on the curved parts on both sides, and these parts are difficult to break, and the long main body parts on both sides of the curved parts are
It has a shape that bulges outward and has a rounded tip, making it extremely safe to use, and the main body automatically expands inside the vagina due to the elasticity of the synthetic resin. This has the effect of making it easier to observe and treat the inside of the vagina.
