[0002] In the current NICU (neonatal intensive care unit) usage scenario, when the child is receiving non-invasive ventilation through nasal congestion or mask while receiving nasogastric feeding through a nasogastric tube, the positive pressure ventilator will push part of the airflow along the esophagus into the digestive system, causing abdominal distension and affecting the process of digesting nutrients in the gastrointestinal tract of the child. This needs to be improved. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a pediatric gastric tube device for preventing abdominal distension and reflux under non-invasive ventilation, which can prevent the airflow of the non-invasive ventilator from rushing into the esophagus of the child during tube feeding.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a pediatric gastric tube device for preventing abdominal distension and reflux under non-invasive ventilation, comprising a tube body, a connector and an airflow blocker, the connector being arranged at the upper end of the tube body, the airflow blocker being arranged at the upper middle part of the tube body, the airflow blocker being arranged in an umbrella shape, and the lower end being connected to the outer wall of the tube body, and the upper end being in an open shape, and the opening position of the airflow blocker is against the inner wall of the esophagus of the child.

[0005] In a preferred example, the present invention can be further configured as follows: a flexible connecting sleeve is disposed at the lower end of the airflow blocker, and a mounting ring fixed to the tube body is disposed at the lower end of the connecting sleeve.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0015] Embodiment 1: like Figure 1 As shown, a pediatric gastric tube device for preventing abdominal distension and reflux under non-invasive ventilation includes a tube body 1, a connector 2 and an airflow blocker 3.

[0016] like Figure 1 As shown, the tube body 1 is used to be inserted into the stomach of the child along the nasal cavity and esophagus, and the lower end of the tube body 1 is provided with a guide head 11 in an arc shape to play a guiding role, so that the tube body 1 can be easily and painlessly inserted into the stomach of the child.

[0017] like Figure 1As shown, the connector 2 is disposed at the upper end of the tube body 1 and is used to connect medical devices such as syringes to implement nasogastric feeding operations.

[0018] like Figure 1 , Figure 2 As shown, the airflow blocker 3 is arranged in the middle and upper part of the tube body 1. The airflow blocker 3 is arranged in an umbrella shape without cracks. The airflow blocker 3 has a thickness of 0.3 mm, a length of 10 mm, a tip diameter of 1 mm, and a tail end diameter of 10 mm after unfolding.

[0019] like Figure 1 , Figure 2 As shown, the material of the airflow blocker 3 is soft medical natural latex, which is soft, skin-friendly, and has low rejection reaction. Under standard operation, it has no irritation to the child and reduces the irritation to the nasopharyngeal tract of the child during nasogastric feeding.

[0020] like Figure 1 , Figure 2 As shown, the lower end of the airflow blocker 3 is connected to the outer wall of the tube body 1, and the upper end is open. The opening position of the airflow blocker 3 contacts the inner wall of the esophagus of the child.

[0021] When the gastric tube device is in use, the lower end of the tube body 1 is inserted into the nasal cavity of the child, and the tube body 1 is gently pushed so that the tube body 1 enters the stomach of the child along the test tube. At the same time, the airflow blocker 3 is placed into the esophagus of the child along with the gastric tube, and automatically opens to fill the gap between the gastric tube and the esophagus.

[0022] When the ventilator is working, since the airflow blocker 3 can block the esophagus, it can ensure that the ventilator will not press the airflow into the digestive system along the esophagus of the child. At the same time, when gas enters, the airflow blocker 3 will be expanded and fit the esophagus more tightly, thereby protecting the child from the influence of the ventilator's ventilation during feeding. At the same time, it also blocks the nutrients in the stomach to prevent the nutrients from flowing back upward, thus realizing the anti-reflux function.

[0023] like Figure 1 , Figure 2 As shown, a flexible connecting sleeve 31 is provided at the lower end of the air flow blocker 3 , and a mounting ring 32 fixed to the pipe body 1 is provided at the lower end of the connecting sleeve 31 .

[0024] Therefore, during the use of the gastric tube, as the gastrointestinal peristalsis occurs, an up and down dragging force will be applied to the tube body 1, so a flexible connecting sleeve 31 is added between the airflow blocker 3 and the tube body 1 to leave a sliding gap between the airflow blocker 3 and the tube body 1 to cope with the pulling force on the gastric tube during gastrointestinal peristalsis and prevent the esophagus of the child from being scratched.

[0025] like Figure 1 , Figure 2As shown, a convex ring 33 is provided at the upper opening of the airflow blocker 3 to better fit the inner wall of the esophagus and increase the release area with the inner wall of the esophagus, fully fill the gap between the gastric tube and the esophagus, and ensure that the ventilator will not press the airflow into the digestive system along the esophagus of the child.

[0026] Embodiment 2: like Figure 3 As shown, the upper end of the tube body 1 is slidably connected with a sleeve 4, the upper end of the sleeve 4 is provided with an end cap 41 threadedly connected to the connector 2, and the lower end is located in the middle of the airflow blocker 3. The upper end of the airflow blocker 3 is provided with a plurality of pull ropes 34, which are inclined downward and connected to the lower end of the sleeve 4.

[0027] When the gastric tube is inserted into the stomach, the end cap 41 is rotated downward first. At this time, the end cap 41 drives the sleeve 4 to rotate and slide downward at the same time. At this time, the sleeve 4 pulls the drawstring 34 to move synchronously, and the drawstring 34 is wound around the outer wall of the sleeve 4. At the same time, the upper end of the airflow blocker 3 is attached to the outer wall of the sleeve 4 to achieve the tightening of the airflow blocker 3, thereby facilitating the insertion of the gastric tube into the stomach.

[0028] When the gastric tube is fully inserted into the stomach, the end cap 41 is rotated upward, and the end cap 41 drives the sleeve 4 to rotate and slide upward. At this time, the sleeve 4 unwinds the pull rope 34 and makes the airflow blocker 3 open and fit the inner wall of the esophagus.

[0029] When the gastric tube needs to be removed, the end cap 41 is rotated downward again. At this time, the end cap 41 drives the sleeve 4 to rotate and slide downward, so that the sleeve 4 winds up the pull rope 34 again, and the upper end of the airflow blocker 3 fits the outer wall of the sleeve 4. Therefore, when the gastric tube is pulled out, the airflow blocker 3 is in a tightened state and will not scratch the esophagus, thereby protecting the esophagus of the child.

[0030] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
