This utility model provides a pediatric gastric tube holder, belonging to the field of gastric tube storage technology. It includes a lower storage box and an upper storage box, with the lower storage box located below the upper storage box and the two boxes connected by a locking mechanism. An elastic clip is fixed to the bottom of the lower storage box; a magnetic strip is embedded and fixed to the bottom of the lower storage box; a lower moving platform is located inside the lower storage box; a suction strip is embedded and fixed to the top of the lower moving platform; and a lower vortex-shaped wire plate and a lower gastric tube guide cover are fixed to the top of the lower moving platform. This utility model allows for a certain amount of displacement for the gastric tube after storage by reserving space inside the lower and upper storage boxes. This allows for the release of a portion of the gastric tube when it is accidentally pulled, preventing it from being pulled out of the patient's body, ensuring normal use of the gastric tube, and reducing patient pain.
