Description

Two-section nasogastric tube plug structure This invention relates to a nasogastric tube, and more particularly to a two-section nasogastric tube plug structure that improves ease of use and safety. With the advancement of science and technology and the development of medical technology, the survival rate of injured and sick patients has significantly improved. However, when patients are unable to eat due to injury, illness or old age, they usually need to be fed through a nasogastric tube to ensure that they get enough nutrition. The nasogastric tube usually needs to be left in the body for three to seven days, but the time may be longer if the patient’s eating condition is poor and the nasogastric tube needs to be used continuously. Traditional nasogastric tubes consist of a long, flexible tube with one end inserted through the nasal cavity into the esophagus and stomach, while the other end remains outside the nose. This design has several drawbacks. First, patients cannot remove the nasogastric tube during use, which may negatively impact their appearance and psychological state. Second, the tube may dislodge when the patient turns over or be accidentally pulled out while administering sedatives. Finally, if the nasogastric tube dislodges, medical staff need to reinstall it, which not only increases their workload but may also cause discomfort to the patient. To address these issues, a two-section nasogastric tube has been developed. This tube consists of a first tube and a second tube. The first tube is inserted into the stomach, while the second tube protrudes outside the nasal cavity. The two tubes can be separated and connected as needed. To prevent contamination and food reflux, when the two tubes are separated, the opening of the first tube is sealed with a cap attached to it. However, the existing two-section nasogastric tube still has some shortcomings. Since the first and second tubes are only connected by a plug, the connection is not stable and is prone to unexpected separation during use, causing inconvenience and making it impractical. In addition, when the first and second tubes are connected, the cap is not fixed, and it not only extends outward but is also easy to shake, which will hinder and affect the user's comfort. Therefore, it is necessary to improve it. In view of the aforementioned drawbacks of conventional two-section nasogastric tubes, the inventor conceived the idea of ​​innovation and, after extensive research, trial production, and numerous revisions and improvements, has launched this invention. This invention discloses a two-section nasogastric tube stopper structure, comprising: a first tube body with a first connector at one end, a fitting portion at the end of the first connector away from the first tube body, an insertion hole axially disposed within the fitting portion, the insertion hole communicating with the first tube body, a stopper on the first connector, the stopper comprising an extension piece and a plug body, the extension piece being connected to the first connector, and the plug body disposed on the extension piece; and a second tube body with a second connector at one end that can be inserted into the first connector. The second connector has a fitting groove at the end away from the second tube body for the fitting part to be inserted. The second connector has a closed locking groove. When the first connector and the second connector are inserted, the locking groove can be used to lock the plug body in and fix it, thereby strengthening the connection stability between the first connector and the second connector and fixing the plug cap. When the second connector is pulled away from the first connector, the fitting groove of the second connector is separated from the fitting part of the first connector, and the plug body of the plug cap can cover and seal the insertion hole. The main purpose of the two-section nasogastric tube plug structure of the present invention is to improve the connection stability of the two-section nasogastric tube, reduce the inconvenience caused by accidental dislodgement, and fix the plug in place to ensure that it is close to the second connector, preventing the plug from shaking, thereby further improving patient comfort and safety. 1: First tube body 10: First Connector 11: Fitting Part 111: Socket 12: Plug the lid 121: Extension 122: Plug 1221: Sealing ring 2: Second tube body 20: Second connector 21: Fitting groove 22: Connector 221: Through hole 23: Locking slot The first figure is a three-dimensional composite diagram of the present invention.

The following description, in conjunction with the drawings of preferred embodiments of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements herein. First, please refer to Figures 1 to 5. The two-section nasogastric tube plug structure of the present invention includes: a first tube body 1 and a second tube body 2. The first tube 1 has a first connector 10 at one end. The end of the first connector 10 away from the first tube 1 has a fitting part 11. The fitting part 11 has an axial insertion hole 111 inside, which is connected to the first tube 1. The first connector 10 also has a plug 12. The plug 12 includes an extension piece 121 and a plug body 122. The extension piece 121 is connected to the first connector 10. The plug body 122 is disposed on the extension piece 121. In this embodiment, the plug body 122 is cylindrical with a round head. The plug body 122 has at least one sealing ring 1221 around its periphery to improve the sealing effect. The sealing ring 1221 is integrally formed with the plug body 122. The second tube 2 is provided with a second connector 20 at one end. The end of the second connector 20 away from the second tube 2 is provided with a fitting groove 21. The fitting groove 21 is provided with a plug part 22. The plug part 22 is provided with a through hole 221. The through hole 221 is connected to the second tube 2. The second connector 20 is provided with a closed locking groove 23 near the second tube 2. In this embodiment, the locking groove 23 is concave arc-shaped. When using the tube for feeding, the first tube 1 is inserted into the patient's stomach through the esophagus via the nasal cavity. The fitting part 11 of the first connector 10 remains outside the patient's nose. The fitting groove 21 of the second connector 20 fits into the fitting part 11 of the first connector 10. The insertion part 22 is inserted into the insertion hole 111, and the plug body 122 of the plug cap 12 is locked into the locking groove 23 of the second connector 20 to complete the stable connection between the second connector 20 and the first connector 10, preventing unexpected separation. The second tube 2 and the first tube 1 are interconnected so that liquid food can be introduced into the patient's stomach through the second tube 2 and the first tube 1 to supplement the required nutrients. After the feeding action is completed, as shown in Figure 6, the plug body 122 of the plug cap 12 can be pulled out of the locking groove 23 of the second connector 20, and then the second connector 20 can be pulled out of the first connector 10. The fitting groove 21 of the second connector 20 is separated from the fitting part 11 of the first connector 10 so that the second tube body 2 can be stored independently. As shown in Figures 7 and 8, the plug body 122 of the plug cap 12 is used to cover and seal the insertion hole 111 to prevent foreign objects from entering the first tube body 1 and causing infection, while also preventing food reflux. Since only the first tube body 1 remains in the patient's body, the aesthetics and comfort of the patient after the nasogastric tube is inserted can be improved, and the risk of accidentally pulling out the nasogastric tube can be significantly reduced. The following benefits can be obtained from the structure of the above specific embodiments: The two-section nasogastric tube plug structure of the present invention can be fixed by the plug body 122 of the plug 12 being inserted into the locking groove 23 of the second connector 20, thereby improving the connection stability between the first tube body 1 and the second tube body 2, reducing the inconvenience caused by accidental detachment, and fixing the plug 12 to ensure that it is close to the second connector 20 and to prevent the plug 12 from shaking randomly, thereby further improving the patient's comfort and safety of use, reducing the interference caused by the plug 12 when using the nasogastric tube, and thus improving the overall user experience. 1: First tube body 10: First Connector 11: Fitting Part 111: Socket 12: Plug the lid 121: Extension 122: Plug 1221: Sealing ring 2: Second tube body 20: Second connector 23: Locking slot
