Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

Example one

As shown in fig. 1, 2 and 3, the three-cavity ultrasonic developing nasal jejunum tube disclosed by the utility model comprises a tube body 1, a gastrointestinal decompression cavity 2, a jejunum feeding cavity 3 and a stomach cavity 4, wherein the bottom of the jejunum feeding cavity 3 is communicated with the top of the tube body 1, the gastrointestinal decompression cavity 2 and the stomach cavity 4 are inserted from the top of the tube body 1 and extend downwards, the middle part of the tube body 1 is provided with a gastrointestinal decompression cavity opening 5 and a stomach cavity opening 6, the bottoms of the gastrointestinal decompression cavity 2 and the stomach cavity 4 are respectively communicated with the gastrointestinal decompression cavity opening 5 and the stomach cavity opening 6 through the inner cavity of the tube body 1, and a zigzag hollow structure is formed between the outer wall of the lower end of the tube body 1 and the inner cavity.
