Example Embodiment

[0011] in figure 1 The gastric juice enters the gap between the inner tube (1) and the outer tube (2) from the side hole (8) of the stomach, and is drawn out through the negative pressure suction device connected with the outer tube conversion cap (7). The inner guide wire (5) in the inner tube enters from the inner tube and can reach the tip of the spiral tube (3), which is convenient for indwelling from the nostril and operation under gastroscope. During the nasal feeding, the infusion set is connected through the inner tube conversion cap (6), and the nutrient solution goes along the inner tube (1) to the side hole (9) of the spiral tube.

[0012] in figure 2 Among them, the cross section of the middle part of the nasogastric jejunum nutrition tube is the gap between the inner tube (1) and the outer tube (2), which can facilitate the extraction of gastric juice.

Abstract

The invention relates to a nasogastric jejunal nutrient tube, which can reduce pressure in the stomach and intestine and provide nutrients for the jejunum. The nasogastric jejunal nutrient tube comprises an inner tube and an outer tube, the inner tube and the outer tube are arranged concentrically and have different diameters, the outer tube is long, the lower end of the outer tube is provided with a spiral tube with a memory function, the spiral tube moves downwards along with gastrointestinal motility, the sharp end of the spiral tube is made of material impermeable for radioactive rays to facilitate fluoroscopy and radiography, the sidewall of the outer tube is provided with a plurality of side holes within the length of a stomach tube, drainage of gastric fluid can be achieved due to a gap between the outer tube and the inner tube, the lower end of the inner tube is arranged under the side holes of the outer tube, the part between the outer side of the lower end of the hollow inner tube and the outer tube is sealed to avoid backflow of nutrient fluid, and a wire can be arranged in the inner tube and reach the sharp end of the spiral tube. By adopting the nasogastric jejunal nutrient tube, retention through the nostril and operations under a gastroscope can be facilitated.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a device capable of simultaneously providing gastrointestinal decompression and jejunum nutrition. Background technique [0002] At present, gastric tube suction is mostly used for gastrointestinal decompression, and the diameter of the tube is relatively thick. Patients who cannot eat often use jejunal nutrition tube for nasal feeding, and gastrointestinal decompression cannot be performed. The patient was intubated in both nostrils at the same time, which was very painful and uncomfortable. Sometimes when the gastric tube was removed, the jejunal nutrition tube was taken out together, requiring re-intubation, which affected the treatment. Contents of the invention [0003] In order to overcome the deficiency that the existing gastric tube and jejunum nutrition tube can not perform gastrointestinal decompression and enteral nutrition at the same time, the present inven...
