Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a gastric tube device for preventing blockage. Background Technology

[0002] A gastric tube is placed in the stomach at one end and exits through the nose or mouth at the other. Its uses include removing stomach contents such as gastric juices, gas accumulated in the gastrointestinal tract, or blood clots from gastrointestinal bleeding, and also delivering nutrients such as necessary fluids, food, and medications.

[0003] Currently, existing gastric tubes often adhere to the stomach wall after insertion, which can block the discharge port at the tube tip, preventing food from entering the stomach smoothly. Once the discharge port is blocked, flushing or re-insertion increases the burden on the patient. For example, Chinese utility model patent CN215780061U discloses a novel gastric tube insertion method with a spiral-shaped tip and a discharge port on the inner side of the spiral, preventing the discharge port from being blocked by the stomach wall and ensuring the tube remains unobstructed. Furthermore, by using a guide wire, the spiral tail can be straightened during insertion, increasing the tube's rigidity and facilitating the procedure. However, in this patent, straightening the spiral tail requires the doctor to use both hands to maintain the relative position of the guide wire and the tube while performing the insertion, undoubtedly increasing the workload for medical staff. Additionally, there is still a risk of relative slippage between the guide wire and the tube, raising concerns about safety.

[0004] In summary, there is an urgent need to design a gastric tube device that prevents blockage and overcomes the aforementioned problems. Utility Model Content
