Further, the multifunctional stomach tube further comprises a guide wire matched with the nasointestinal tube.

Preferably, the guidewire is 145cm in length.

Preferably, the length of the pipe body is 95 cm.

Preferably, the nasointestinal tube has a length of 145 cm.

The stomach tube subassembly includes above-mentioned multi-functional stomach tube and the paraffin oil cotton ball in bags, body, nose intestines pipe and solid fixed ring dress are in same wrapping bag.

Compared with the prior art, the utility model discloses following beneficial effect has:

1, the utility model can be used as a nasointestinal tube or a stomach tube independently; the naso-intestinal tube and the stomach tube can be used simultaneously, for example, when the naso-intestinal tube is used for tube feeding, the stomach tube end can reduce the pressure of the stomach and the intestine;

2, the utility model discloses can adjust the length that the nose intestines tube front end stretches out the body according to actual conditions, realize the position of stomach tube and nose intestines tube then.

Detailed Description

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 the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

As shown in fig. 1-5, the utility model discloses a multifunctional stomach tube, which comprises a tube body 1, a naso-intestinal tube 3, a fixing ring 2 and a guide wire 4 adapted to the naso-intestinal tube 3. There are first lumen 11 and second lumen 12 of mutual independence in the body 1, and body 1 distal end has a plurality of and the communicating through-hole 13 of first lumen 11, and first lumen 11 near-end has the external joint to use as the stomach tube.

The second lumen 12 has an internal thread 14 at its proximal end, and the fixing ring 2 has an external thread 21 at its one end which is adapted to the internal thread 14.

The length of nose intestines pipe 3 is greater than the length of

body

1, and 3 outer walls of nose intestines pipe are equipped with

length scale

32, and 3 distal ends of nose intestines pipe have a plurality of holes 31, and the external diameter of nose intestines pipe 3 is less than the internal diameter of second lumen 12 to in with the relaxed second lumen 12 of inserting of nose intestines pipe 3.

The fixing ring 2 has an inner hole for interference fit with the outer diameter of the nasointestinal tube 3. Preferably, the inner diameter of the fixing ring 2 is equal to or slightly smaller than the outer diameter of the nasointestinal tube 3.
