観察して診断、治療を行う技術が開発され、同技
術には超小型のテレビカメラが使用されている。
Recently, in medical diagnosis and treatment, especially in the field of dentistry, a technology has been developed that allows diagnosis and treatment to be performed by viewing TV images and observing affected areas within the body, especially the oral cavity. It is used.
このような医療、診断用のカメラにおいては、
カメラのレンズ部分を含む先端鏡胴部は人の体内
（口腔内）に挿入するので、外部の細菌等が体内
に入るのを防止するために厳重に殺菌を行わなけ
ればならない。
In such medical and diagnostic cameras,
Since the tip barrel of the camera, including the lens part, is inserted into the human body (oral cavity), it must be thoroughly sterilized to prevent external bacteria from entering the body.

ことができるものでなければならない。 To simply cover the lens, you can cover it with a transparent filter such as a UV filter similar to that used for general cameras, but this cannot cover the lens barrel at the tip of the ultra-compact television camera that approaches or inserts into the oral cavity. . Furthermore, there is an adjustment mechanism such as an aperture ring on the lens barrel, and I would like to cover this as well, but it must be possible to adjust the aperture.
そこで本考案は、超小型テレビカメラの先端部
全体を感染から防止するとともに、絞りリング等

ある。 The sanitary cap of the present invention is molded from transparent synthetic resin, such as urea resin, polyethylene resin, polyvinyl chloride resin, methacrylic resin, etc., and its size is the same as the aperture ring of the ultra-small medical camera. It has a diameter and length that covers the lens barrel. Therefore, the diameter, length, etc. of this sanitary cap are as follows:
This depends on the size of the medical camera to which it is applied.

絞りが操作できる。 The sanitary cap of the present invention is attached to the tip of a medical camera as described above. The sanitary caps are completely sterilized before installation, and the required number is prepared and replaced with an unused one each time. Even when operating the medical camera with the sanitary cap attached, since the top surface of the cap body 1 is mirror-polished part 2, camera operations such as photographing can be performed as is. Also, since the protrusion 4 of the cap body 1 is fitted into the lens aperture ring 5, if you press the protrusion 4 of the cap body 1 with your finger from the outside of the cap body 1 and turn it, you can aperture the lens with the sanitary cap attached. can be operated.
