SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model aims to provide a nasal-insertion type inflatable stomach supporting guide tube, which can be inserted through the nose by reducing the diameter of an insertion tube, and simultaneously solves the problems that the insertion tube is difficult and a thick tube easily damages the pharyngeal posterior wall and the esophageal mucosa.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a nasal insertion inflatable gastric support guide tube comprising: the stomach supporting and guiding tube comprises a stomach supporting and guiding tube body, an inflatable air bag arranged on the stomach supporting and guiding tube body and a multi-side-hole absorption head arranged at the end part of the stomach supporting and guiding tube body.
In the above-mentioned nasal-insertion type inflatable stomach supporting guide tube, the diameter of the stomach supporting guide tube body is the same as that of the F14 oral-nasal-insertion type inflatable stomach supporting guide tube, and the diameter is 4.62 mm.
The diameter of the inflated air bag after being inflated is the same as that of the F32 oral-nasal-insertion inflatable stomach supporting guide tube, and is 10.56 mm.
In the above-mentioned nasal-insertion type inflatable stomach supporting guide tube, the length of the stomach supporting guide tube body is 100 cm.
In the nasal-insertion type inflatable stomach supporting guide tube, the length of the porous part is 4 cm.
The length of the inflatable air bag of the nose-inserted inflatable stomach supporting guide tube is 20cm, and the nose-inserted inflatable stomach supporting guide tube is positioned at the position of 4-24cm of the stomach supporting guide tube body.
In the above-mentioned nasal-insertion type inflatable stomach support guiding tube, the inflation volume of the inflatable air bag is 43 ml.
In the nasal-insertion type inflatable stomach support guide tube, the multi-side-hole absorption head is provided with four through holes, and the interval between every two through holes is 5 mm.
The diameter of the through hole of the nose-inserted type inflatable stomach support guide tube is 3 mm.
In the nasal-insertion type inflatable stomach support guide tube, the inflation air bag is connected with an inflation catheter, and the inflation catheter has the length of 70cm and the diameter of 1 mm.
The utility model has the advantages that:
the diameter of the intubation is reduced, so that the intubation can be inserted through the nose, the problems that the intubation is difficult and the thick tube easily damages the pharyngeal posterior wall and the esophageal mucosa are solved, the intubation is convenient, and the damage is reduced;
the inflatable air bag is arranged, so that a stomach supporting guide tube can be formed in a local stomach cavity for surgical guidance, the stomach tube does not need to be replaced, and the effects of the stomach supporting guide tube and a postoperative drainage stomach tube are simultaneously finished through one-time intubation in the surgery;
Reduce the pain of the patient and improve the operation efficiency.
