[0032] Please refer to Figures 1-6, the present utility model provides a technical solution: a nasogastric feeding device, including a container, a tube body 1, a connecting tube, a nasointestinal tube 2 and a pulling part. The container is used for containing enteral nutrition suspension. The upper end of the tube body 1 is fixedly connected to the container, and the tube body 1 communicates with the inner cavity of the container. The upper end of the connecting tube is fixedly connected to the lower end of the tube body 1, and the connecting tube communicates with the tube body 1, that is, the inner cavity of the connecting tube communicates with the inner cavity of the tube body 1. The inlet end of the nasointestinal tube 2 is inserted and connected to the lower end of the connecting tube, and the inner cavity of the nasointestinal tube 2 communicates with the inner cavity of the connecting tube. The lower end of the pulling part is fixedly connected to the inlet end of the nasointestinal tube 2, and the pulling part is used for detachably and fixedly connecting to the connecting tube. The nasointestinal tube is a common medical supply on the current market, so its specific structure and usage method will not be elaborated here.

[0033] The initial state of the nasogastric feeding device described in the present utility model is: the upper end of the tube body 1 is fixedly connected to the container, and the upper end of the connecting tube is fixedly connected to the lower end of the tube body 1; the lower end of the pulling part is fixedly connected to the inlet end of the nasointestinal tube 2, the lower end of the connecting tube and the inlet end of the nasointestinal tube 2 are in a separated state, and the upper end of the abutting part is in a separated state from the connecting tube.

[0034] Before using the nasogastric feeding device described in the present utility model to infuse enteral nutrition suspension into the patient's intestine, insert the outlet end of the nasointestinal tube 2 into the patient's nasal cavity, so that the outlet end of the nasointestinal tube 2 passes through the pharynx, esophagus and stomach and enters the duodenum or jejunum, and the inlet end of the nasointestinal tube 2 is located outside the patient's body. Then hang the container filled with enteral nutrition suspension on the infusion stand. Then insert and connect the lower end of the connecting tube to the inlet end of the nasointestinal tube 2, specifically insert the lower end of the connecting tube into the inner cavity of the inlet end of the nasointestinal tube 2. Then fixedly connect the upper end of the pulling part to the connecting tube. Then enteral nutrition suspension can be infused into the patient's intestine, and the enteral nutrition suspension in the container can flow through the tube body 1, the connecting tube and the nasointestinal tube 2 in sequence and enter the patient's intestine.

[0035] During the process of using the nasogastric feeding device described in the present utility model to infuse enteral nutrition suspension into the patient's intestine, since the lower end of the pulling part is fixedly connected to the inlet end of the nasointestinal tube 2 and the upper end of the pulling part is fixedly connected to the connecting tube, the pulling part is used to pull the connecting tube towards the nasointestinal tube. When the nasointestinal tube 2 is accidentally pulled by the patient, the pulling part can be held between the inlet end of the nasointestinal tube 2 and the connecting tube, that is, the pulling part can pull the connecting tube towards the nasointestinal tube 2, which can reduce the possibility of the connecting tube slipping out of the inlet end of the nasointestinal tube 2 and reduce the possibility of the interruption of enteral nutrition infusion.

[0036] In this embodiment, the connecting tube includes an insertion section 3 and a connecting section 4. The insertion section 3 is used to be inserted into the inner cavity of the inlet end of the nasoenteric tube 2. The insertion section 3 is matched with the inner cavity of the inlet end of the nasoenteric tube 2. The lower end of the connecting section 4 is integrally formed with the upper end of the insertion section 3. The upper end of the connecting section 4 is fixedly connected to the lower end of the tube body 1. Specifically, the upper end of the connecting section 4 can be integrally formed with the lower end of the tube body 1. A plurality of annular grooves 5 are formed by inward depression on the outer peripheral surface of the connecting section 4;

[0037] The pulling part includes a flexible sleeve 7 fixedly connected to the outer surface of the inlet end of the nasoenteric tube 2 at the lower end and sleeved on the inlet end of the nasoenteric tube 2, and a plurality of binding ropes 8 fixedly arranged in the middle on the flexible sleeve 7. The flexible sleeve 7 has a circular tubular structure. The flexible sleeve 7 is made of rubber material. The flexible sleeve 7 is sleeved around a plurality of the annular grooves 5. A plurality of the binding ropes 8 correspond to a plurality of the annular grooves 5 one by one. Specifically, after the insertion section 3 is completely inserted into the inner cavity of the inlet end of the nasoenteric tube 2, and when the flexible sleeve 7 is in a state of being straightened but not stretched in its length direction, a plurality of the binding ropes 8 are directly opposite to a plurality of the annular grooves 5 one by one. The binding ropes 8 are used to bind the flexible sleeve 7 in the corresponding annular groove 5, that is, the binding ropes 8 are used to bind the flexible sleeve 7 in the annular groove 5 corresponding to the binding ropes 8.

[0038] Since the insertion section 3 is matched with the inner cavity of the inlet end of the nasoenteric tube 2, when the insertion section 3 is inserted into the inner cavity of the inlet end of the nasoenteric tube 2, the inlet end of the nasoenteric tube 2 can be inserted and connected with the insertion section 3, and the inlet end of the nasoenteric tube 2 can also be inserted and connected with the lower end of the connecting tube. Since the upper end of the connecting section 4 is integrally formed with the lower end of the tube body 1, the connecting section 4 can be stably fixedly connected with the tube body 1, so that the connecting tube is not easily detached from the tube body 1.

[0039] After the insertion section 3 is completely inserted into the inner cavity of the nasoenteric tube 2, a medical staff member holds the nasoenteric tube 2 with one hand and pulls the upper end of the flexible sleeve 7 upward with the other hand to make the flexible sleeve 7 in a straightened state and in a state of not being stretched. At this time, a plurality of the binding ropes 8 are directly opposite to a plurality of the annular grooves 5 one by one. Another medical staff member can tie the two ends of the binding rope 8 together to bind and fix the flexible sleeve 7 in the corresponding annular groove 5. At this time, the flexible sleeve 7 is fixedly connected to the connecting tube, and thus the pulling part can be fixedly connected to the connecting tube. It is more convenient to fixedly connect the pulling part to the connecting tube.

[0040] In this embodiment, a first convex ring 9 is formed by outward protrusion on the outer surface of the inlet end of the nasointestinal tube 2, and the lower edge of the flexible sleeve 7 is fixedly connected corresponding to the edge of the first convex ring 9.

[0041] Since the first convex ring 9 is formed by outward protrusion from the outer surface of the inlet end of the nasointestinal tube 2, that is, the first convex ring 9 is fixed on the outer surface of the inlet end of the nasointestinal tube 2, and the lower edge of the flexible sleeve 7 is fixedly connected corresponding to the edge of the first convex ring 9. With this structure, the flexible sleeve 7 can be fixedly connected to the outer surface of the inlet end of the nasointestinal tube 2.

[0042] In this embodiment, a second convex ring 10 is formed by outward protrusion on the outer peripheral surface of the connecting section 4. The second convex ring 10 is located above the uppermost annular groove 5. An external thread 11 is further formed on the outer peripheral surface of the connecting section 4, and the external thread 11 is located above the second convex ring 10;

[0043] The connecting pipe further includes a threaded sleeve 12 threadedly connected to the external thread 11; an annular receiving groove 13 is formed between the threaded sleeve 12 and the second convex ring 10.

[0044] The flexible sleeve 7 is made of an airtight material. Specifically, the flexible sleeve 7 is made of a rubber material. The lower end of the flexible sleeve 7 is hermetically connected to the outer surface of the inlet end of the nasointestinal tube 2, that is, air cannot enter the flexible sleeve 7 through the connection position between the lower end of the flexible sleeve 7 and the outer surface of the inlet end of the nasointestinal tube 2, and air or liquid cannot be discharged from the flexible sleeve 7 through the connection position between the lower end of the flexible sleeve 7 and the outer surface of the inlet end of the nasointestinal tube 2. The upper part of the flexible sleeve 7 is sleeved around the second convex ring 10 and the threaded sleeve 12.

[0045] After the flexible sleeve 7 is bundled and fixed in the corresponding annular groove 5 by the bundling rope 8, the part of the flexible sleeve 7 corresponding to the receiving groove 13 is pressed into the receiving groove 13. Then, the threaded sleeve 12 is rotated on the connecting section 4 to move the threaded sleeve 12 downward, that is, to move the threaded sleeve 12 toward the second convex ring 10. The part of the flexible sleeve 7 pressed into the receiving groove 13 can be pressed and held by the threaded sleeve 12 against the second convex ring 10. Since the flexible sleeve is made of an airtight material, the lower end of the flexible sleeve is hermetically connected to the outer surface of the inlet end of the nasointestinal tube 2. At this time, the part of the flexible sleeve 7 located below the threaded sleeve 12 can form a sealed space. When the connection between the connecting section 4 and the inlet end of the nasointestinal tube 2 becomes loose, even if enteral nutrition suspension enters the part of the flexible sleeve 7 located below the threaded sleeve 12, the enteral nutrition suspension entering the part of the flexible sleeve 7 located below the threaded sleeve 12 cannot leak out from the part of the flexible sleeve 7 located below the threaded sleeve 12.

[0046] Rotate the threaded sleeve 12 on the connecting section 4 to move the threaded sleeve 12 upward, that is, to move the threaded sleeve 12 away from the second convex ring 10, so as to release the abutment of the threaded sleeve 12 against the part of the flexible sleeve 7 pressed into the receiving groove 13. Then, untie the plurality of bundling ropes 8, and the flexible sleeve 7 can be detached from the connecting tube, that is, the pulling part can be detached from the connecting tube.

[0047] In this embodiment, a nasal feeding device of the present utility model further includes a rubber band 14 looped around the threaded sleeve 12. The rubber band 14 is circular. The rubber band 14 is used to bundle the flexible sleeve on the part of the connecting section 4 located between the second convex ring 10 and the threaded sleeve 12.

[0048] When the rubber band 14 is looped around the threaded sleeve 12, the ring formed by the rubber band 14 is in a state of being expanded by the threaded sleeve 12, that is, the rubber band 14 is in a stretched state. When the rubber band 14 is in an unstretched state, the diameter of the inner hole of the ring formed by the rubber band 14 is smaller than the diameter of the connecting section 4.

[0049] After the flexible sleeve 7 is bundled and fixed in the corresponding annular groove 5 by the bundling rope 8, the rubber band 14 can be moved downward to the position of the receiving groove 13. At this time, the rubber band 14 can press all the part of the flexible sleeve 7 corresponding to the receiving groove 13 into the receiving groove 13 under the action of its own elastic force, and the rubber band 14 can hoop the part of the flexible sleeve 7 corresponding to the receiving groove 13 on the part of the connecting section 4 corresponding to the receiving groove 13. In this way, the part of the flexible sleeve 7 corresponding to the receiving groove 13 can be pressed into the receiving groove 13, which is more convenient when pressing the part of the flexible sleeve 7 corresponding to the receiving groove 13 into the receiving groove 13.

[0050] In this embodiment, a nasal feeding device of the present utility model further includes a medicine adding tube 15 and a valve 16. The medicine adding tube 15 is fixedly connected to the outer peripheral surface of the connecting tube, the valve 16 is arranged on the medicine adding tube 15, and the inner cavity of the medicine adding tube 15 communicates with the inner cavity of the connecting section 4.

[0051] During the process of infusing enteral nutrition suspension into the patient's intestine, the nipple of a syringe containing medicine can also be inserted into the end of the medicine adding tube 15 facing away from the connecting tube, and then the valve 16 is opened. The medicine is injected into the connecting tube through the syringe and the medicine adding tube 15. The medicine entering the connecting tube can enter the patient's intestine through the nasointestinal tube 2, that is, the medicine adding tube 15 can play a role in adding medicine to the nasointestinal tube 2. After the medicine adding is completed, the valve 16 is closed, and then the nipple of the syringe is pulled out of the medicine adding tube 15. It is not necessary to pull out the connecting tube from the inlet end of the nasointestinal tube 2 and then add medicine from the inlet end of the nasointestinal tube 2, which is more convenient when adding medicine to the nasointestinal tube 2.

[0052] In this embodiment, one end of the medicine adding tube 15 is fixedly connected to the connecting section 4, and the other end of the medicine adding tube 15 inclines downward. With this structure, the nozzle at the end of the medicine adding tube 15 facing away from the connecting tube can face obliquely downward, so that dirt is not easily introduced into the medicine adding tube 15.

[0053] In this embodiment, the container includes a barrel 17, a cylinder 18, a through hole, and a soft rubber plug 19. The barrel 19 is a circular barrel. The upper end of the barrel 17 is open, and the lower end of the barrel 17 is closed. The cylinder 18 is fixedly connected to the lower end surface of the barrel 17. The through hole is formed in the bottom plate of the barrel 17, and the through hole communicates the inner cavity of the cylinder 18 and the inner cavity of the barrel 17. The soft rubber plug 19 is fixedly arranged in the cylinder 18, and the soft rubber plug 19 is matched with the inner cavity of the cylinder 18. The upper end of the tube body 1 is fixedly connected with a bottle stopper puncture device 20. The bottle stopper puncture device is a common medical supply component in the market. Specifically, the bottle stopper puncture device is relatively common in existing infusion sets, so the specific structure and usage method thereof will not be elaborated herein.

[0054] When the container holds the enteral nutrition suspension, the enteral nutrition suspension is contained in the barrel 17. When it is necessary to add the enteral nutrition suspension into the barrel 17, the enteral nutrition suspension can be added into the barrel 17 through the opening at the upper end of the barrel 17. By puncturing the soft rubber plug 19 from bottom to top with the bottle stopper puncture device 20, the upper end of the tube body 1 can be fixedly connected to the soft rubber plug 19, and the upper end of the tube body 1 can also be fixedly connected to the container.

[0055] In this embodiment, an external thread is formed on the outer peripheral surface of the upper end of the barrel 17. The container further includes a screw cap 21 threadedly connected to the upper end of the barrel 17. The screw cap 21 is used to close the opening at the upper end of the barrel 17. A ventilation hole 22 vertically penetrating the top plate is formed on the top plate of the screw cap 21. By providing the screw cap 21, the possibility of dirt falling into the barrel 17 can be reduced. By providing the ventilation hole 22, the inner cavity of the barrel 17 can be communicated with the external air. During the process of infusing the enteral nutrition suspension into the patient's intestine, negative pressure in the barrel 17 can be prevented, and the enteral nutrition suspension in the barrel 17 can flow out more smoothly.

[0056] In this embodiment, the nasal feeding device of the present utility model further includes a drip chamber 23 and a flow regulator provided on the tube body 1. The flow rate of the enteral nutrition suspension flowing through the tube body 1 can be adjusted by the flow regulator. The drip rate of the enteral nutrition suspension can be more intuitively observed through the drip chamber 23, and thus the speed of the enteral nutrition suspension flowing in the tube body can be observed. The drip chamber and the flow regulator are common structural components on existing infusion sets, so the specific structure and usage method of the drip chamber and the flow regulator will not be elaborated herein.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
