Miniature image connection device with guiding function

This creation belongs to the field of medical endoscopy, in particular to a miniature image connection device with guiding function.

Press, tracheal cannula intubation is through the mouth or nose through the throat, glottis and placed into the living trachea to form a ventilation tube. Generally, the tracheal tube is placed in the human trachea, and a new tracheal tube must be replaced in the human trachea about one to two weeks to prevent bacterial infection, or the inner wall of the human trachea and the tracheal tube are stuck, or in the trachea When the cannula airbag ruptures, the tracheal cannula must be replaced immediately. At present, when a new tracheal tube is to be replaced, the old tracheal tube must be removed from the mouth to replace the new tracheal tube. When replacing a new tracheal tube, the human trachea must be irradiated through the oral cavity with a light-emitting flexible tube or a laryngoscope in advance, and then the new tracheal tube can be entered from the oral cavity, and partially inserted into the human trachea.

However, the way of illuminating the human trachea through the oral cavity with the luminous flexible tube or laryngoscope not only cannot clearly observe the position of the human trachea, but also when the new tracheal tube is installed in the human trachea, the new tracheal tube cannot be surely in place In the human trachea, it is inconvenient for the operator to replace the new tracheal tube. Therefore, when replacing the tracheal tube, the luminous flexible tube or laryngoscope must be used to detect the need to align the new tracheal tube to the exact position of the human trachea, and then insert the new tracheal tube in the human trachea. , Causing more discomfort and inconvenience for patients.
