患者は、実際の状況に応じて第１の管体１と第２の管体５とを接合するか第２の管体５を取り除き、例えば、栄養剤を投与しない場合、第２の管体５を取り外すことができるため、第２の管体５が鼻の外側に垂れ下がることがない。そのため、患者の外観が他人と異なることによりじろじろ見られることを防ぐことができる上、患者は、第２の管体５を取り外してマスクを直接付けた場合、他人からは患者に経鼻胃管が取り付けられていることが分からないため、患者が恥ずかしい思いをすることがない。 As can be seen from the above, the nasogastric tube structure of the present invention uses the coupling member 6 to movably join and separate the first tube body 1 and the second tube body 5. It has the characteristics that can be done.
The patient joins the first tube body 1 and the second tube body 5 or removes the second tube body 5 according to the actual situation, for example, when no nutrient is administered, the second tube body Since 5 can be removed, the second tubular body 5 does not hang down outside the nose. Therefore, it is possible to prevent the patient's external appearance from being different from others, and in addition, when the patient removes the second tube 5 and directly attaches the mask, the other person gives the patient a nasogastric tube. The patient does not feel embarrassed because it is not known that is attached.
