Description

Nasogastric tube

Technical Field

The utility model relates to the technical field of a nasogastric feeding medical device, in particular to a universal nasointestinal and nasogastric tube.

Background Art

Nasogastric feeding is a method in which a tube is artificially placed into the digestive tract through the nasal cavity when the patient is in a coma and unable to eat independently. The food is then ground into a paste or other liquid food using a grinder. A large syringe is used to connect the large injection port under the gastric tube connector. After the connection is secure, the push rod piston is manually pressurized to pump water and food into the patient's stomach or intestines to help patients who cannot swallow independently provide water and food to maintain metabolism, weight and nutrition in the body. Currently, the commonly used nasogastric tubes are nasogastric tubes and nasointestinal tubes. If the patient's gastric function is effective and the gastric motility is sufficient, a nasogastric tube is generally inserted into the patient's stomach, and the food is digested by the stomach. If the patient's gastric motility is insufficient or even the gastric function is damaged, a nasointestinal tube will be used to enter the intestine through the pylorus, and the food will be directly absorbed by the intestine.

However, medical staff have found in clinical practice that critically ill patients generally have more or less impaired gastric function or insufficient gastric motility after surgery, but they will gradually recover after postoperative care. In this case, a nasogastric tube is currently inserted in the early stage, and after the doctor evaluates the recovery of gastric function, the nasogastric tube must be removed and another nasogastric tube inserted. This will increase the patient's pain, and two intubations will also increase the possibility of digestive tract injury.

A trachea A12 and a trachea B13 are respectively provided on the side wall of the nasogastric tube 18 and on two opposite sides located at one end of the three-way tube 2. The trachea A12 is communicated with the nasogastric tube limiting air bag 7, and the trachea B13 is communicated with the nasogastric tube limiting air bag 8. A connecting tube 20 matching the port B10 is provided at one end of the nasogastric tube 18 corresponding to the three-way tube 2, and a liquid hole B19 penetrating the tube wall B of the nasogastric tube 18 is provided on the side wall of the other end. When the nasogastric tube 18 extends into the nasogastric tube 1 from the port B10 of the three-way tube 2, and the connecting tube 20 is fixedly connected to the port B10, the end of the nasogastric tube 18 provided with the liquid hole B19 extends out of the nasogastric tube 1 from the position of the flap-like structure.

There are multiple liquid holes A6, which are evenly distributed in multiple rows with the axis of the nasogastric tube 1 as the center, and each row of liquid holes A6 is evenly spaced along the axial direction of the nasogastric tube 1; there are multiple liquid holes B19, which are evenly distributed in multiple rows with the axis of the nasogastric tube 18 as the center, and each row of liquid holes B19 is evenly spaced along the axial direction of the nasogastric tube 18.

The trachea A12 and the trachea B13 are respectively connected to the nasogastric tube limiting airbag 7 and the nasointestinal tube limiting airbag 8 through the tracheal cavity 14 provided in the tube wall of the nasogastric tube 1.

The nasogastric tube limiting airbag 7 is an annular airbag coaxially arranged in an annular groove 16 provided on the outer wall of the nasogastric tube 1, and the annular groove 16 is connected to the tracheal cavity 14 connected to the trachea A12.

The nasogastric tube limiting airbag 8 is a plurality of strip-shaped airbags evenly distributed with the axis of the nasogastric tube 1. The strip-shaped airbags are respectively arranged in the corresponding strip-shaped grooves 17 on the inner wall of the inner cavity A3 of the nasogastric tube 1. The strip-shaped grooves 17 are respectively connected to the tracheal cavity 14 connected to the trachea B13 through the annular holes 15 coaxially arranged with the nasogastric tube 1.

The ends of the trachea A12 and the trachea B13 away from the nasogastric tube 1 are respectively connected to each other and are provided with an air valve nozzle 22 for connecting to the inflation device.

The connecting pipe 20 is detachably sealed and fixedly connected to the port B10 of the tee pipe 2 .

A sealing plug connector 21 matching the tee pipe 2 is coaxially fixedly disposed on one end of the connecting pipe 20 facing the tee pipe 2 .

The port C11 is located between the trachea A12 and the trachea B13, and the phase angle between the port C11 and the trachea A12 and the phase angle between the port C11 and the trachea B13 are both 90 degrees.

When the connecting tube 20 fixed to the port B10 is fixed at the patient's nostril, the nasogastric tube limiting airbag 7 is located at the junction of the patient's esophagus and stomach, the spherical surface 5 of the nasogastric tube 1 is located in the patient's stomach, and one end of the nasointestinal tube 18 with the liquid hole B19 is located in the patient's intestine.

When the present application is used, as shown in FIG3 , the nasogastric tube 1 is first inserted from the patient's nostrils according to the requirements of the nasogastric tube insertion technique until the liquid-passing hole A6 at the end where the spherical arc surface 5 of the nasogastric tube 1 is located is located in the patient's gastric cavity. At this time, the nasogastric tube limiting airbag 7 is still located in the patient's esophageal tube, and air is inflated into the nasogastric tube limiting airbag 7 through the connecting trachea A12, so that the nasogastric tube limiting airbag 7 is expanded and tightened at the corresponding position of the esophagus to achieve a relatively fixed position of the nasogastric tube 1 after the nasogastric tube limiting airbag 7 is expanded; at this time, according to the requirements of the gastrointestinal tube direct insertion technique, one end of the nasogastric tube 18 provided with the liquid-passing hole B19 is inserted from the port B10 of the three-way tube 2, so that the nasogastric tube 18 enters the inner cavity A3 of the nasogastric tube 1 through the port A9 of the three-way tube 2, and continues downward along the inner cavity A3 of the nasogastric tube 1. When the nasogastric tube 18 contacts the spherical arc surface 5 of the nasogastric tube 1 Afterwards, the end of the nasointestinal tube 18 opens the flap-like structure of the spherical surface 5 and continues to extend the nasogastric tube 1 downward into the patient's gastric cavity. Then, under the peristalsis of the patient's stomach, the nasointestinal tube 18 passes through the pylorus with the assistance of the endoscope and continues to enter the patient's intestine; when one end of the nasointestinal tube 18 provided with a connecting tube 20 contacts the port B10 of the three-way tube 2, the end of the nasointestinal tube 18 corresponding to the liquid hole B19 just extends into the patient's intestine to the designated position, and the guide wire in the nasointestinal tube 18 is taken out; then, as shown in Figure 4, the connecting tube 20 is first fixed to the three-way tube 2 through the plug-in connector 21, and then the nasointestinal tube limiting airbag 8 is inflated through the connecting trachea B13, so that the nasointestinal tube limiting airbag 8 is expanded and then the corresponding position of the nasointestinal tube 18 is tightened to achieve the relative fixation of the position of the nasointestinal tube 18 and the nasogastric tube 1. Finally, as shown in FIG. 5 , after the three-way tube 2 is fixed to the patient's nose by a fixing device such as medical tape, the gas in the nasogastric tube limiting airbag 7 and the nasointestinal tube limiting airbag 8 can be discharged through the respective air nozzle valves 22 of the connecting trachea A12 and the connecting trachea B13.

As shown in FIG4 , the nasogastric tube limiting airbag 7 and the nasointestinal tube limiting airbag 8 are both filled with air, and the nasointestinal tube 18 is relatively fixed to the nasogastric tube 1, and the nasogastric tube 1 is relatively fixed to the patient's esophagus. When the patient's condition is relatively serious, and the gastric motility is insufficient or even the gastric function is impaired, liquid food or water is directly injected into the nasointestinal tube 18 through the connecting tube 20 and then directly enters the intestine for feeding; when the patient's gastric function is normal, liquid food or water is directly injected into the nasogastric tube 1 through the port C11 of the three-way tube 2 and then directly enters the stomach for feeding. According to the patient's recovery, if the patient's gastric function is completely fine, the nasointestinal tube 18 can be removed from the nasogastric tube 1 alone, and only the nasogastric tube 1 needs to be retained; if the patient's gastric function has recovered but is still unstable, the nasointestinal tube 18 still needs to be retained in the nasogastric tube 1.

As shown in FIG5 , after the utility model is inserted, in the state of not eating, the nasogastric tube limiting airbag 7 and the nasointestinal tube limiting airbag 8 are both in a contracted state, thereby avoiding long-term compression of the esophagus and causing discomfort to the patient, and also preventing the nasointestinal tube from continuing to extend into the intestine under the peristaltic action of the stomach and intestine. When it is necessary to remove the nasointestinal tube and the nasogastric tube at the same time, the device for fixing the connecting tube 20 to the patient's nose is directly removed, and then the nasogastric tube 1 is directly removed together with the nasointestinal tube 18 through the connecting tube 20, thereby improving efficiency.
