Description

a nasogastric tube

technical field

The utility model relates to the field of gastric tubes, in particular to a nasogastric tube.

Background technique

Nasogastric gavage (nasogastricgavage) is to manually insert a gastric tube into the esophagus through the nasal cavity in a special medical environment to help patients who cannot swallow spontaneously to provide nutrient solution. The gastric tube used is usually a special nasogastric gastric tube. In modern medical care, nasogastric tube is widely used to solve the problem of swallowing difficulties in clinical infants and young children, especially for infants and young children with micromandibular deformity, severe laryngeal cartilage dysplasia and functional dysphagia. Children with esophageal stenosis, esophagotracheal fistula, esophageal fistula and other esophageal defects, to ensure the normal supply of nutrient solution for patients.

In the prior art, the nasogastric tube only has a single lumen tube, through which the nutrient solution can be introduced into the stomach, which can only solve the feeding problem of children. Because the stomach of the child will continue to secrete gastric juice, and the child who needs nasal feeding is usually complicated with symptoms such as gastroesophageal reflux, in the process of nasal feeding, the strong acid stomach contents of the child repeatedly reflux into the child's esophagus. Even in the oral cavity, it is easy to cause symptoms such as vomiting and coughing in children. At the same time, the strongly acidic gastric contents are also destructive to the esophagus and oral cavity of children. At the same time, children are often prone to dysphagia. Difficulty swallowing can cause a large amount of fluid to remain in the throat of the child for a long time, often causing repeated aspiration pneumonia and difficult to improve, not only requiring long-term hospitalization, but sometimes even lead to life-threatening severe pneumonia.

At present, the main way to solve the problem of nasogastric tube reflux is to insert a jejunal feeding tube. However, the process of placing a jejunal feeding tube is quite troublesome, and it often requires the child to be placed under general anesthesia. As well as expensive costs, but also not conducive to the physical and mental health of children. In addition, the jejunal feeding tube does not have the function of sucking sputum, and it often requires professional medical staff to perform manual sputum suction operation.

The end just blocks the interface between the esophagus and the stomach (ie: spout door), thus effectively preventing the reflux of the strongly acidic gastric contents to the esophagus and even the mouth, reducing the risk of gag reflex and aspiration pneumonia in children, and also effectively avoiding the Erosion of the esophagus and even the mouth by strongly acidic stomach contents.

As shown in FIG. 2 and FIG. 3 , in order to facilitate the clamping of the end of the anti-reflux tube 2 and the injection of gas or liquid, the anti-reflux tube 2 further includes a variable balloon 21 , a balloon tube 22 and a pipe joint 23 , the balloon tube 22 is fixed on one side wall of the nutrition tube 1 , one end of the balloon tube 22 is fixedly connected with the variable balloon 21 , and the lumen of the balloon tube 22 leads to the inner cavity of the variable balloon 21 The other end of the balloon tube 22 is fixedly connected with the tube joint 23, and the lumen of the balloon tube 22 communicates with the inner cavity of the tube joint 23. The tube joint 23 is usually connected with a syringe or other inflatable and liquid filling equipment. When the anti-reflux tube 2 is not filled with gas or liquid, the variable balloon 21 is in an uninflated state, and usually has the same appearance as the end of the balloon tube 22, that is, when the nasogastric tube is inserted into the stomach of the child, the variable balloon The balloons 21 are all in an uninflated state, which facilitates the insertion of the nasogastric tube from the nasal cavity into the stomach. After the nasogastric tube is inserted into the stomach of the child, gas or liquid is injected into the anti-reflux tube 2 through a syringe or other inflatable or liquid filling equipment, and the gas or liquid is transmitted to the variable balloon 21 through the balloon tube 22 , the internal pressure of the variable balloon 21 gradually increases and expands, so that the variable balloon 21 is in an inflated state, that is, the variable balloon 21 becomes a spherical state. At this time, gently pull the anti-reflux tube 2 outward. And fixed on the child's nose, the variable balloon 21 will gently hold the spray door, thereby effectively preventing the child's strongly acidic gastric contents from refluxing into the esophagus or even the mouth. The variable balloon 21 can be a single cavity (not shown in the drawings), and the variable balloon 21 of the single cavity can be fixed around the periphery of the nutrition tube 1 . Further preferably, considering the convenience of processing, the variable balloon 21 can also form a cavity together with the nutrition tube 1, the nutrition tube 1 passes through the middle of the variable balloon 21, and the inner cavity of the variable balloon 21 is formed by The outer wall of the nutrition tube 1 and the inner wall of the variable balloon 21 are surrounded by such a structure that when the variable balloon 21 is in an uninflated state, the shape is almost the same as that of the balloon tube 22, and the form is very similar to the end of the balloon tube 22, The variable balloon 21 is spherical only when it is inflated or filled with fluid.

As shown in FIG. 2 , in order to facilitate the insertion of the injection end of a syringe or other inflatable and liquid-filled equipment into the pipe joint 23, the pipe joint 23 includes a buffer cavity 231 and an injection plug 232. One end of the buffer cavity 231 is a conical cavity 000, and a balloon The other end of the tube 22 communicates with the end of the conical cavity 000 , and the injection plug 232 is fixed on the inner wall of the other end of the buffer cavity 231 . The injection end of the syringe or other inflatable and liquid-filled equipment can be inserted into the injection plug 232. After the injection end of the syringe or other inflatable or liquid-filled equipment is pulled out, the injection plug 232 can quickly return to its original state, with excellent sealing performance, effectively ensuring resistance to resistance. The air pressure inside the reverse flow pipe 2 is stable. The buffer cavity 231 has a certain buffering effect, so that the gas or liquid flowing into the variable balloon 21 is more stable.

In order to facilitate the uniform flow of liquid food into the stomach of the child from the end of the nutrition tube 1, further, a number of liquid food holes 11 are provided on the side wall of the end of the nutrition tube 1. Since the several liquid food holes 11 are located on the side wall, it is not easy to be sealed. Blocking, and can evenly transport food in the stomach. Preferably, the head end of the nutrient tube 1 is connected to a pipe joint 12, and the pipe joint 12 can be more conveniently connected with the nutrient solution supply device to realize nutrient solution supply.
