Abstract

The invention discloses an automatic telescopic child stomach tube device capable of preventing abdominal distension and regurgitation under noninvasive ventilation. The device is used for preventing abdominal distension of a child patient under noninvasive ventilation. A nasal gastrointestinal tube head, a controller, an automatic breathing machine airflow blocker, a stomach tube body and a supporting strip form a whole, the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube, in the process of using the stomach tube, medical workers place the stomach tube with the automatic breathing machine airflow blocker into the stomach through the esophagus of a child patient, and the stomach tube with the automatic breathing machine airflow blocker is fixed to the upper middle portion of the stomach tube. After the controller is pressed down, the airflow blocker of the automatic breathing machine fills the gap between the stomach tube and the esophagus, the situation that airflow enters the stomach through the esophagus to cause abdominal distension of a child patient in the application process of the non-invasive breathing machine is avoided, meanwhile, the influence of gastric regurgitation on the child patient is prevented, and therefore the situation that feeding of the child patient is affected by non-invasive ventilation is prevented.

Description

Technical Field

[0001] This invention, "Non-invasive ventilation anti-abdominal distension and anti-reflux automatic retractable pediatric gastric tube," is a medical device developed to prevent gastric reflux and the influx of non-invasive ventilator airflow into the esophagus of infants during tube feeding. Due to its standard gastric tube size design and the addition of an automatic ventilator airflow blocker, it boasts advantages such as high ease of use, high practicality, low learning cost, and low operating cost, making it easy to promote and use. Background Technology

[0002] In current NICU (Neonatal Intensive Care Unit) settings, when infants are non-invasively ventilated via nasal cannula or mask and simultaneously fed through a nasogastric tube, the positive pressure ventilator may force some airflow down the esophagus into the digestive system, leading to abdominal distension and affecting the progress of nutrition in the gastrointestinal tract. This patented "Automatic Retractable Pediatric Gastric Tube for Non-invasive Ventilation" is a medical device developed to prevent gastric reflux and the influx of non-invasive ventilator airflow into the infant's esophagus during tube feeding. Summary of the Invention

[0003] To prevent abdominal distension caused by positive pressure ventilators forcing some airflow into the digestive system through the esophagus during tube feeding and non-invasive ventilation via nasal cannula or face mask, thus affecting the nutritional process in the child's gastrointestinal tract, the "non-invasive ventilation anti-abdominal distension and anti-reflux automatic retractable pediatric gastric tube" device was invented. This medical device was developed to prevent gastric reflux and the influx of non-invasive ventilator airflow into the child's esophagus during tube feeding.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: The non-invasive ventilation anti-abdominal distension and anti-reflux automatic retractable pediatric gastric tube device consists of five parts: the gastric tube head, controller, automatic ventilator airflow blocker, gastric tube body, and support strip. The main body of the device is the controller and the automatic ventilator airflow blocker fixed in the upper part of the gastric tube. When medical staff use this non-invasive ventilation anti-abdominal distension and anti-reflux automatic retractable pediatric gastric tube, pressing the controller causes the automatic ventilator airflow blocker to extend under the action of the support strip until it completely conforms to the curvature of the inner wall of the child's esophagus, preventing reflux. It also prevents nasogastric feeding during nasal or mask non-invasive ventilation, where the positive pressure ventilator forces some airflow into the digestive system through the esophagus, leading to abdominal distension and affecting the progress of nutrition in the child's gastrointestinal tract. After use, pressing the controller causes the automatic ventilator airflow blocker to slowly retract to its initial shape under the action of the support strip, allowing the gastric tube to be removed.

[0005] When medical staff use this non-invasive ventilation, anti-abdominal distension, anti-reflux, and automatically retractable pediatric gastric tube, the automatic ventilator airflow blocker is inserted into the child's esophagus along with the gastric tube to fill the esophageal gaps and protect the child from the influence of ventilator ventilation during feeding.

[0006] The advantages of this patent are as follows: Because the automatic respiratory airflow blocker uses medical-grade natural latex, this material is soft, skin-friendly, and has a low rejection rate. Under standardized operation, it causes no irritation to the child, reducing irritation to the nasopharynx during nasogastric feeding. Furthermore, because this invention adopts a standard pediatric nasogastric tube size design, it boasts advantages such as high ease of use, high practicality, low learning cost, and low operating cost, making it easy to promote and use.

[0008] The non-invasive ventilation anti-abdominal distension and anti-reflux automatic telescopic pediatric gastric tube device consists of five parts: ① gastric tube head, ② controller, ③ automatic ventilator airflow blocker, ④ gastric tube body, and ⑤ support bar. The main body of the device consists of two parts: the controller ② and the automatic ventilator airflow blocker ③ fixed in the upper part of the gastric tube. Detailed Implementation

[0009] This invention is called an automatic retractable pediatric gastric tube for preventing abdominal distension and reflux under non-invasive ventilation. The main body consists of a controller and an automatic ventilator airflow blocker made of latex material fixed in the upper part of the gastric tube. It can prevent gastric reflux and the influx of non-invasive ventilator airflow into the child's esophagus during tube feeding, protecting the child from the influence of ventilator ventilation during feeding.

[0010] The gastric tube is 180mm long, 2mm in outer diameter, and 1.2mm in inner diameter. The body of the gastric tube is made of polyurethane, a material that is delicate, relatively soft, and durable, which can reduce irritation to the infant's gastric mucosa.

[0011] This automatic ventilator airflow blocker for non-invasive ventilation, designed to prevent abdominal distension and reflux, and features an automatically retractable pediatric gastric tube. When closed, it is 0.3mm thin, 2mm long, and has a 1mm tip diameter. The airflow blocker is elastic and retractable, with several support bars fixed around its perimeter. Pressing the controller causes it to extend through these support bars, preventing gastric reflux. When fully extended, the airflow blocker is 0.3mm thin, 10mm long, and has a 1mm tip diameter. The extended tail end has a diameter of 15mm, forming a seamless, cone-shaped medical-grade natural latex ring. After deployment, the airflow blocker automatically conforms to the curvature of the esophageal wall, based on the size of the child's esophagus, preventing reflux through gaps.

[0012] When closed, the support bar is 0.6mm thin, 2mm long, and 0.5mm wide, made of foldable polypropylene. When fully extended, it is 0.6mm thin, 9.5mm long, and 0.5mm wide. This material is lightweight, soft, and has excellent support, making it suitable as a support material for automatic breathing airflow blockers. Due to its good heat resistance and chemical resistance, it ensures stability and safety in the human body.

[0013] When using an automatic retractable pediatric gastric tube with anti-abdominal distension and anti-reflux function during non-invasive ventilation, medical staff insert the gastric tube with an automatic ventilator airflow blocker into the stomach through the child's esophagus. After pressing the controller, the automatic ventilator airflow blocker will fill the gap between the gastric tube and the esophagus, protecting the child from airflow entering the stomach through the esophagus during non-invasive ventilation, thus preventing abdominal distension. It also prevents gastric reflux from affecting the child, thereby preventing non-invasive ventilation from affecting the child's feeding.
