The gastric tube is composed of a polyurethane or silicone plastic tube with different thickness specifications of about 105 cm, a gastric tube clamp, a gastric tube inlet joint, and a cross knot plug. The gastric tube helps patients who cannot swallow to deliver necessary water and nutrition under special circumstances.

[0003] During traditional cricopharyngeal muscle rehabilitation, every time the cricopharyngeal muscle balloon dilation technique is performed, it is necessary to reinsert a two-lumen catheter through the nasal cavity. After the cricopharyngeal muscle balloon dilation technique is completed, the two-lumen catheter needs to be removed. Repeated intubation will increase the pain and psychological burden of the patient. In addition, although the catheter is a sterile item, some patients still mind. Moreover, the friction or pressure during balloon inflation causes the local tissue temperature to rise, which is likely to cause thermal injury. Therefore, there is an urgent need for a new type of multi-lumen gastric tube capable of performing cricopharyngeal muscle balloon dilation. Summary of the Utility Model
