Description

A kind of gastrointestinal nutrition nasal feeding tube

Technical field: this utility model relates to technical field of medical instruments, particularly a kind of improvement of gastrointestinal nutrition nasal feeding tube.

Background technology: at present, the gastrointestinal nutrition nasal feeding tube of Ying Yonging is a single lumen catheter clinically, opening opens wide, and during use, how to fix at wing of nose place with medical proof fabric, when standing up or mismatch, patient easily stomach tube is deviate from, the intubate rapid wear injures one's stomach and esophageal mucosa membrane injury repeatedly, cause suffering to patient, and long-term nasal feeding patient cardia is loose, gastric content is backflowed, the possibility of the aspiration pneumonitis of causing is arranged.Opening is contaminated easily, unhygienic, and when the nasal feeding patient needed oxygen uptake simultaneously, the nostril, both sides all was inserted with pipeline, and is very painful.

Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art part, provides a kind of nasal feeding oxygen uptake to enter from same pipeline, reduces patient's misery, and the nasal feeding tube fixation can not deviate from, and gastric content does not backflow.The gastrointestinal nutrition nasal feeding tube that can keep opening cleaning, health.

This utility model is achieved through the following technical solutions: comprise insertion end, opening, body, the top of insertion end has preceding hole, side that side opening is arranged, form by oxygen channel, airbag gas passage, passage of food three chambeies in the body, on the opening of opening medicated cap is arranged, its underpart connects an one-way piston and communicates with the air bag of insertion end bottom by the airbag gas passage on the body, the opening bottom connects the oxygen path and communicates with the intravital oxygen channel of pipe, on the oxygen channel of below, oxygen path junction oxygen side single hole is arranged.During use, after insertion end inserted from nasal cavity, open the medicated cap on the opening of its opening, opening and syringe nipple are closely linked, elder generation's pumpback, seeing has gastric juice to extract out, proves that its insertion end has entered gastric, injects air from the one-way piston mouth and makes the air bag air-blowing, outwards pulling gently, make air bag and cardia closure, nasal feeding tube is difficult for deviating from like this, can prevent that gastric content from backflowing from loose cardia, cause aspiration pneumonitis or formation to suffocate, during oxygen uptake, the oxygen path is linked to each other with oxygen generator, can cure by oxygen therapy.

This utility model compared with prior art has following advantage: this utility model nasal feeding tube, owing to can form air bag, can block cardia securely at gastric, and be difficult for from stomach, deviating from; Opening has medicated cap, can prevent to pollute; Be connected with the oxygen path on it, the nasal feeding oxygen uptake enters from same pipeline, reduces patient's misery.

Description of drawings: accompanying drawing is this utility model structural representation.

The specific embodiment: this utility model nasal feeding tube, comprise insertion end 1, opening 2, body 3, the top of insertion end 1 has preceding hole 11, side that side opening 9 is arranged, form by oxygen channel 12, airbag gas passage 14, passage of food 13 3 chambeies in the body 3, medicated cap 4 is arranged on the opening of opening 1, and its underpart connects an one-way piston 5 and communicates with the double-lumen air sac 10 of insertion end bottom by the airbag gas passage 14 on the body 3; The oxygen channel 12 that opening 2 bottoms connect in oxygen path 7 and the body 3 communicates, and on the oxygen channel 12 of below, oxygen path 7 junctions oxygen side single hole 6 is arranged: there is the oxygen helmet 8 on the top of its oxygen path 7: the double-lumen air sac capacity is 10ml.During making, nasal feeding tube with medium size insertion depth 50cm is example: length overall 100cm, have scale, establish a two-chamber air bag 10 at distance insertion end 7cm place, respectively there are a plurality of side openings 9, diameter 3mm in both sides in the insertion end 1 following 7cm, there is preceding hole 11 on the top, internal diameter 3mm: the external diameter 5mm of opening 2, internal diameter 3mm: there is an one-way piston 5 at the 3cm place below opening 2, communicates by the double-lumen air sac 10 of the airbag gas passage 14 on the body 3 with insertion end 1 bottom.20cm place, opening 2 below has an oxygen pipeline 7, opening 2 below 25-30cm sections that a plurality of oxygen side single hole 12 is arranged, and all communicates with oxygen channel 12 in the body 3.General clinically patient's hairline to the distance of xiphoid-process is the stomach tube insertion depth, inserts nasal feeding tube according to measuring distance, make oxygen side single hole 12 at nasal cavity apart from nose 7-8cm place, generally insertion depth is that measuring distance adds 2cm again, prevents that double-lumen air sac 10 is in esophagus.Open the medicated cap 4 on the opening of its opening 2, opening and syringe nipple are closely linked, elder generation's pumpback, seeing has gastric juice to extract out, proves that its insertion end 1 has entered gastric, behind the opening injection air of one-way piston 5, outwards pulling gently, then double-lumen air sac 10 and cardia closure make nasal feeding tube be difficult for deviating from, can prevent that gastric content from backflowing from loose cardia, cause aspiration pneumonitis or formation to suffocate.During oxygen uptake, open the oxygen helmet 13 of oxygen path, connect oxygen supply device and cure by oxygen therapy.Its double-lumen air sac is 10ml, can not cause gastric mucosal lesion.

Claims (3)
