Description of the Related Art Conventionally, a catheter used for administration of nutrients, liquid medicines and drugs to the intestine and a catheter used for suction and decompression in the digestive tract are performed using different things, and therefore, for each purpose of both. The catheter was inserted and removed. Repeated insertion / removal of a catheter used for insertion into the intestine from the stomach via the abdominal wall and the stomach through the duodenum through the abdominal wall and stomach wall is a heavy burden on the patient and a considerable burden on the practitioner. . However,
No catheter that can avoid this burden has been proposed.
Further, with a conventional catheter, it is not possible to aspirate and decompress the gastrointestinal tract over a wide range. In this case, even if gastroenteral nutritional administration is performed, gastric aspiration and decompression cannot be performed, so that gastric juice and saliva etc. accumulated in the stomach cannot be prevented from flowing back, such as aspiration pneumonia. Cause complications of
It may cause serious medical problems.

る。[0010] Even if the above-mentioned administration is sent to the back of the intestine using a conventional catheter, and the backflow thereof is prevented, the pyloric ring is blocked to some extent by the inserted and indwelled catheter tube, Gastric juice and saliva tend to accumulate in the stomach, and the accumulated liquid flows backward to cause the above-mentioned complications. Therefore, the present invention proposes a catheter that enables both suction and decompression in the digestive tract with nutrients, drug solutions and drugs, and reduces the burden on patients and practitioners.
Moreover, it aims at obtaining an appropriate medical effect.

First, the distal end of the catheter tube has a length that can be inserted through the stomach to a position beyond the duodenum, thereby enabling the administration of nutrients, drug solutions, and drugs to the intestine. Second, forming multiple lumens in the catheter tube,
In one of the lumens, a side hole is formed in a range from the body of the stomach to a portion beyond the pylorus, and the side hole enables suction and decompression in the digestive tract. As another effect of the side hole, even if the pylorus ring is obstructed to some extent as described above, the side hole and the lumen communicating therewith can be bypassed, and gastric juice and saliva can be prevented from being stored in the stomach. In addition to the above configuration, there is provided a means for limiting a portion for aspirating and depressurizing the gastrointestinal tract according to symptoms and medical purposes.

べきである。FIG. 4 is a partially enlarged explanatory view showing a state where a stop rod (8) used for closing the hole (7) is fitted, and FIG. 5 is a perspective view of the stop rod (8). . The stop rod (8) is formed in a semicylindrical shape, the cross-sectional shape is slightly larger than the cross-sectional shape of the sublumen (3), and when fitted, the upper surface of the stop rod (8) is below the hole (7). To a size that can be completely covered, and fitted using the elasticity of the catheter tube (1). When the stop rod (8) is singly fitted, the sub-lumen (3) is closed between the front and rear of the fitted portion, so that the suction and decompression portions can be limited. However, since it is possible to leave the utility of the bypass in some cases, if it is necessary to stop the utility of the bypass for a medical purpose, it is conceivable to fit a plurality of the utilities. FIG. 6 is an explanatory view showing a state in which a tubular covering (9) is fitted to the catheter tube (1) instead of the stop rod (8). Since the cover (9) can be shifted in the front and rear, the cover (9) is formed to have a length capable of covering all of the holes (7), and is used by being appropriately shifted or used.
It is possible to select whether or not the number of occlusions is partially stopped. The superiority of the stop lot (8) and the covering (9) is selected depending on the medical purpose, because the former has an effect of damming by fitting, whereas the latter has no effect of damming when fitted. Should.
