PROBLEM TO BE SOLVED: To provide an inexpensive technology to reduce pain of a patient when phlegm is sucked out.SOLUTION: A larynx camera unit 200 is used in combination with a portable instrument having a lens constituting part of a camera and an illumination. The larynx camera unit 200 includes an illumination light transmission member 223 and an image light transmission member 222, both of which are rod-like and inserted into an oral cavity. An illumination light from the illumination of the portable instrument is sent to the larynx by the illumination light transmission member 223, and an image light from the larynx is sent to the portable instrument from the back of the uvula by the image light transmission member 222. A user performs phlegm sucking while checking an image displayed on a display unit of the portable instrument.SELECTED DRAWING: Figure 2【課題】痰の吸引の際における患者の苦痛を低減させることのできる、安価な技術を提供することをその課題とする。【解決手段】喉頭カメラユニット２００は、カメラの一部をなすレンズと照明とを持つ可搬機器と組合せて用いられる。喉頭カメラユニット２００はいずれもが棒状で口腔内に挿入される、照明光伝達部材２２３と像光伝達部材２２２とを持つ。可搬機器の照明からの照明光は、照明光伝達部材２２３によって喉頭に送られ、喉頭からの像光は、像光伝達部材２２２によって口蓋垂の奥から可搬機器に送られる。可搬機器のディスプレイに表示の画像を確認しながらユーザは、痰の吸引を行う。【選択図】図２
