Medical instruments for introduction into the respiratory tract of a patient

A medical instrument for insertion into the respiratory tract of a patient, comprising:

• a flexible tube which is morphologically stable in cross-section, and having a distal extension formed of a flat strip,
• said flexible tube being insertable by means of said extension through the mouth and pharynx cavities of the patient up to and into the oesophagus thereof,
• said flexible tube having an opening closable by means of a tongue located on said flexible tube, said opening of said flexible tube being located above said extension and, on insertion of the instrument, said opening is laterally alignable with the larynx of the patient, whereby secretions may be extracted from, and curative agents, internal tubes, guiding elements, probes, endoscopes and catheters are insertable into the respiratory tract of the patient via said flexible tube opening,
• said flexible tube further including a sloping baffle or partition, extending in the area of said flexible tube opening from the rearward wall area of said flexible tube slopingly downwards towards the front thereof, and establishing an even transition to the lower distal terminal portion of said flexible tube opening, so that a catheter, an internal tube, a guiding element, and a endoscope, which are insertable as the proximal extremity into said flexible tube, can be inserted into the patient's respiratory tract along said baffle or partition, and
• two air or venting tubes, which are open at the proximal side thereof, joined to said flexible tube and extending parallel thereto, each of said two air or venting tubes having a distal opening adjacent to said opening of said flexible tube, said extension having a width that is substantially equal to the width of the structure comprising the flexible tube and the two air or venting tubes.
