Description

Unexpected pull-out prevention stomach tube device

Technical Field

The utility model belongs to the technical field of medical consumables, and particularly relates to an accidental-pull-out prevention gastric tube device.

Background

Gastric tubes are used in special situations to assist patients who cannot swallow in delivering the necessary moisture and food. The stomach tube is respectively an oral stomach tube and a nasal feeding tube. Wherein, the oral gastric tube is inserted through the mouth; the nasal feeding tube needs to be inserted through nostril, reaches stomach through esophagus through pharyngeal portion, is easy to deviate from, should paste firmly, prevents repetition intubate and mistake inhale.

Aiming at the problem that the stomach tube is easy to deviate from, the prior art scheme is mainly of 2 types. One is to add a balloon structure in the gastric cavity part, because the gastric cardia is narrower, when the gastric tube is pulled out, the balloon can be blocked by the gastric cardia, thus preventing the gastric tube from being pulled out further. The second scheme is mainly to clamp and fix the gastric tube at the outlet nose of the gastric tube, such as high-viscosity application and a clamp (the clamp is fixed on the head after clamping the gastric tube) (the clamping position can be determined after the gastric tube is only inserted into each patient because the depth of the gastric tube is different) (the gastric tube is extremely dangerous for the patient who performs gastric surgery and oesophageal surgery to insert the gastric tube again), and the scheme has the defect that the gastric tube still has the risk of falling out and breaking when the gastric tube is violently pulled out.
