Hollow probe for irrigation of the digestive tract of the human or animal body, especially for irrigation of the stomach

摘要

In a hollow probe (1) for irrigation of the digestive tract of the human or animal body, especially for irrigation of the stomach, through the inner duct (10) delimited by the pipe of the hollow probe (1) continuous irrigation is to be facilitated while avoiding any significant increase in the outer cross-section and any reduction of the inner cross-section of the hollow probe. This is achieved in that an outer duct (20) of a thin material is arranged so as to rest tightly against the outside of the pipe (2) and has an opening (9, 16; 40) in the region of the insertion end (4) and in the extracorporeal region (5) and widens to a flow cross-section when the irrigation liquid flows through it.
