Description

Nasogastric tube structure

The present disclosure relates to a nasogastric tube structure, and more particularly to a nasogastric tube structure that is easy to replace.

When patients are unable to swallow food on their own due to poor physical condition or unclear consciousness, medical staff often need to use nasogastric tubes to assist patients in eating. Nasogastric tubes are mainly inserted from the patient's nasal cavity, through the esophagus and into the stomach, so that liquid food can be directly transferred to the patient's stomach through the tube of the nasogastric tube to supplement the necessary nutrients, or even provide the necessary medicines, thereby maintaining the patient's life.

For hygiene and safety reasons, a nasogastric tube must be replaced after being used for a period of time. However, when replacing a traditional nasogastric tube, the old nasogastric tube can only be directly extracted from the patient's body and then the new nasogastric tube is reinserted into the patient's body. This requires medical staff to repeatedly try to guide the nasogastric tube to be smoothly inserted into the correct position in the patient's body each time a new nasogastric tube is inserted. This not only causes operational difficulties for medical staff, but also wastes their precious time, and it is also easy to cause discomfort to patients during the nasogastric tube insertion process.

Therefore, how to design a nasogastric tube structure that can solve the above-mentioned problems is indeed a problem that needs to be solved urgently.

The present disclosure provides a nasogastric tube structure that is easy to replace. To this end, the nasogastric tube structure disclosed herein includes a hollow tube body, a housing structure, and a metal guide, wherein the hollow tube body includes a through-tube and a first end and a second end opposite to each other, and the through-tube forms a first opening at the first end and a second opening at the second end; the housing structure is combined with the hollow tube body to form a housing space and includes a slit and an open end and a closed end opposite to each other, wherein the housing space forms an insertion port at the open end, and the slit extends from the insertion port at the open end toward the closed end; and the metal guide can be detachably inserted into the housing space of the housing structure.

In at least one embodiment of the present disclosure, the metal guide comprises an inserting portion and a hook portion, and the inserting portion is connected to the hook portion. In some embodiments of the present disclosure, when the metal guide is inserted into the receiving space of the receiving structure, the inserting portion passes through the insertion port and is located in the receiving space, while the hook portion is exposed outside the receiving space.

In at least one embodiment of the present disclosure, the metal guide member hooks the open end of the accommodating structure through the hook portion.

In at least one embodiment of the present disclosure, the cross-sectional diameter of the insertion portion of the metal guide is not less than the slit width of the slit of the accommodating structure.

In at least one embodiment of the present disclosure, the accommodating structure is made of elastic plastic material.

In at least one embodiment of the present disclosure, the length of the insertion portion of the metal guide is not less than the slit length of the slit of the accommodating structure.

In at least one embodiment of the present disclosure, the open end of the containing structure is connected to the first end of the hollow tube, and the closed end of the containing structure is located between the first end and the second end of the hollow tube.

In at least one embodiment of the present disclosure, the overall width of the metal guide is smaller than the cross-sectional diameter of the through-pipe.

In at least one embodiment of the present disclosure, the hollow tube has a first tube wall portion and a second tube wall portion, and the tube wall thickness of the first tube wall portion is greater than the tube wall thickness of the second tube wall portion.

As shown in FIGS. 1 to 3 , the nasogastric tube structure 1 of the present disclosure mainly includes a hollow tube body 10, a containing structure 20 and a metal guide 30, wherein the hollow tube body 10 is the main structure of the nasogastric tube structure 1 of the present disclosure. In at least one embodiment of the present disclosure, the hollow tube body 10 is a long straight flexible tube, and the hollow tube body 10 includes a through-line 11 and a first end 12 and a second end 13 opposite to each other. In some embodiments of the present disclosure, the through-line 11 forms a first opening 111 at the first end 12 and a second opening 112 at the second end 13; in other words, the through-line 11 runs through the entire hollow tube body 10 from the first opening 111 formed at the first end 12 of the hollow tube body 10 to the second opening 112 formed at the second end 13 of the hollow tube body 10.

In some embodiments of the present disclosure, the hollow tube 10 further includes at least one side hole 16 disposed on the tube wall of the hollow tube 10 near the second end 13 , so that the through-line 11 is laterally connected to the external environment through the at least one side hole 16 .

In at least one embodiment of the present disclosure, the hollow tube 10 is made of an elastic plastic material, so that the hollow tube 10 can be bent or deformed at will after being subjected to force, so as to facilitate insertion into the patient's body. In some embodiments of the present disclosure, the material of the hollow tube 10 can be polyvinyl chloride (PVC), polyurethane (PU) or silicone, but is not limited thereto.

In at least one embodiment of the present disclosure, the hollow tube body 10 has a first tube wall portion 14 and a second tube wall portion 15, and the tube wall thickness of the first tube wall portion 14 is greater than the tube wall thickness of the second tube wall portion 15, so that the hollow tube body 10 forms a structure with uneven tube wall thickness, wherein the first tube wall portion 14 is used to combine or set the accommodating structure 20. In some embodiments of the present disclosure, the hollow tube body 10 may be provided with one or more through holes on the tube wall adjacent to the second end 13 to meet the needs of combining different instruments or connecting different parts of the hollow tube body 10, but the number or location of the through holes in the present disclosure is not limited thereto.

In at least one embodiment of the present disclosure, the accommodating structure 20 is combined with the side wall of the hollow tube 10, and the accommodating structure 20 can be used to accommodate the metal guide 30. As shown in FIG. 2 , in at least one embodiment of the present disclosure, the accommodating structure 20 is formed with an accommodating space S, and the accommodating structure 20 includes a slit 21 and an open end 22 and a closed end 23 opposite to each other. In at least one embodiment of the present disclosure, the accommodating space S forms an insertion port S1 at the open end 22 and extends toward the closed end 23, so that the accommodating space S forms a semi-open straight strip space; in other words, the accommodating space S is a semi-open straight strip space located between the open end 22 and the closed end 23.

As shown in FIG. 1 and FIG. 2 , the slit 21 extends from the insertion port S1 of the open end 22 along the side wall of the accommodating structure 20 toward the closed end 23, so that the accommodating space S formed by the accommodating structure 20 can be connected to the external environment through the slit 21, but the slit 21 does not extend through the closed end 23. In at least one embodiment of the present disclosure, the slit 21 has a set slit width, for example, 0.1 cm, 0.2 cm, 0.3 cm, 0.4 cm or 0.5 cm, and this is not the case. In some embodiments of the present disclosure, the accommodating structure 20 can also be made of an elastic plastic material, so that the accommodating structure 20 can be bent or deformed at will after being subjected to force, and the slit 21 can also change its width due to the force. In some embodiments of the present disclosure, the material of the accommodating structure 20 can be the same as or different from the material of the hollow tube 10, and there is no special limitation in the present disclosure.

In at least one embodiment of the present disclosure, since the first tube wall portion 14 of the hollow tube body 10 has a relatively large tube wall thickness, the receiving structure 20 can be selectively disposed on the first tube wall portion 14, and the receiving space S is formed at an appropriate position of the first tube wall portion 14. In some embodiments of the present disclosure, when the hollow tube body 10 and the receiving structure 20 are made of the same material, the hollow tube body 10 and the receiving structure 20 can be integrally formed; in other embodiments of the present disclosure, when the hollow tube body 10 and the receiving structure 20 are made of different materials, the hollow tube body 10 and the receiving structure 20 can also be integrally formed by secondary injection or dual-material injection, which is not particularly limited in the present disclosure.

As shown in FIG. 1 and FIG. 2 , in an embodiment of the present disclosure, the open end 22 of the accommodating structure 20 is connected to the first end 12 of the hollow tube 10, and the closed end 23 of the accommodating structure 20 is located between the first end 12 and the second end 13 of the hollow tube 10. In other words, the open end 22 of the accommodating structure 20 is flush with the first end 12 of the hollow tube 10, so that the insertion port S1 of the accommodating space S and the first opening 111 of the through-pipe 11 are located on the same plane, but the present disclosure is not limited thereto. According to actual design requirements, the open end 22 of the accommodating structure 20 may also be higher or lower than the first end 12 of the hollow tube 10, and there is no special limitation in the present disclosure.

As also shown in FIG. 1 and FIG. 2 , the metal guide 30 can be detachably inserted into the receiving space S of the receiving structure 20, and the metal guide 30 is used to provide a guiding function when replacing a new nasogastric tube. In at least one embodiment of the present disclosure, the metal guide 30 includes an insertion portion 31 and a hook portion 32, and the insertion portion 31 is connected to the hook portion 32. In some embodiments of the present disclosure, the insertion portion 31 forms a linear or rod-shaped structure, and the hook portion 32 forms a hook-shaped structure. In some embodiments of the present disclosure, when the metal guide 30 is inserted into the receiving space S of the receiving structure 20, the insertion portion 31 passes through the insertion port S1 of the receiving space S and is located in the receiving space S, and the hook portion 32 is exposed outside the insertion port S1 of the receiving space S. As shown in FIG. 2 , in at least one embodiment of the present disclosure, when the metal guide 30 is inserted into the accommodation space S of the accommodation structure 20, the metal guide 30 hooks the open end 22 of the accommodation structure 20 through the hook portion 32, so that the metal guide 30 can be fixed. In some embodiments of the present disclosure, the metal guide 30 can be made of a hard metal or alloy material, and the metal guide 30 has a bendable property, but the material selection of the metal guide 30 is not limited thereto.

In at least one embodiment of the present disclosure, in terms of structural design, the cross-sectional diameter of the insertion portion 31 of the metal guide 30 is not less than the slit width of the slit 21 of the accommodating structure 20; in other words, in a general state where no external force is applied to the metal guide 30, the insertion portion 31 of the metal guide 30 will be confined in the accommodating space S and cannot be separated from the slit 21 of the accommodating structure 20. In some embodiments of the present disclosure, when the insertion portion 31 of the metal guide 30 is too long, the insertion portion 31 of the metal guide 30 can be stopped by the closed end 23 of the accommodating structure 20 to prevent the metal guide 30 from easily detaching from the accommodating structure 20 when the insertion portion 31 of the metal guide 30 is inserted into the accommodating space S of the accommodating structure 20 due to the insertion portion 31 of the metal guide 30 passing through the closed end 23.

In addition, in at least one embodiment of the present disclosure, the overall width of the metal guide 30 is smaller than the cross-sectional diameter of the through-pipe 11 of the hollow tube body 10, so that the metal guide 30 can pass through the first opening 111 and the second opening 112 of the through-pipe 11 along the extension direction of the insertion portion 31, and then pass through the through-pipe 11.

As shown in FIG. 1 , in at least one embodiment, the nasogastric tube structure 1 of the present disclosure may further include a cover 40, which removably closes the first opening 111 of the through-tube 11 of the hollow tube 10. When the cover 40 closes the first opening 111, foreign matter can be prevented from entering the through-tube 11 through the first opening 111, or liquid food or liquid in the through-tube 11 can be prevented from overflowing from the first opening 111. In at least one embodiment of the present disclosure, the cover 40 includes a connector 41, and the cover 40 is connected to the first end 12 of the hollow tube 10 via the connector 41. Thus, in some embodiments of the present disclosure, when the cover 40 does not close the first opening 111, the cover 40 can still remain connected to the hollow tube 10, so that medical personnel can operate the cover 40 and close the first opening 111 at any time, and the cover 40 can be prevented from falling or being lost.

Please refer to FIG. 1 and FIG. 4A to FIG. 4E, wherein FIG. 4A to FIG. 4E are schematic diagrams of the operation steps for replacing the nasogastric tube structure disclosed herein. As shown in FIG. 4A, in a normal use state, the nasogastric tube structure 1 disclosed herein has been inserted into the patient's nasal cavity so that the second end 13 of the hollow tube body 10 is located in the patient's stomach. At this time, the first end 12 of the hollow tube body 10 and the open end 22 of the accommodating structure 20 are located outside the patient's nasal cavity, and the metal guide 30 (please refer to FIG. 4B to FIG. 4E) has been withdrawn from the accommodating space S of the accommodating structure 20. Therefore, medical personnel can inject liquid food, medicine or liquid through the first opening 111 of the through-conduit 11 of the hollow tube body 10.

In at least one embodiment of the present disclosure, when a patient needs to replace a nasogastric tube, a medical staff member may first insert a metal guide member 30 into the accommodation space S of the accommodation structure 20, and use the closed end 23 of the accommodation structure 20 to abut against the insertion portion 31 of the metal guide member 30, as shown in FIG4B. Then, the medical staff member may first apply an external force to the metal guide member 30, so that the insertion portion 31 of the metal guide member 30 moves toward the side wall of the accommodation structure 20, and then the metal guide member 30 may be separated from the accommodation space S of the accommodation structure 20 through the slit 21, as shown in FIG4C.

In at least one embodiment of the present disclosure, after the metal guide 30 is separated from the accommodating structure 20, the medical staff can only extract the hollow tube 10 of the nasogastric tube structure 1 of the present disclosure from the patient's body, while the insertion portion 31 of the metal guide 30 of the nasogastric tube structure 1 of the present disclosure remains in the patient's body, and the hook portion 32 of the metal guide 30 is still located outside the patient's nasal cavity.

In at least one embodiment of the present disclosure, medical personnel may prepare another set of new nasogastric tube structures 1a from which the metal guide piece has been pulled out. Before the new nasogastric tube structure 1a is inserted into the patient's nasal cavity, the metal guide piece 30 retained in the patient's body is first passed through the second opening 112a of the through-tube 11a and enters the through-tube 11a, and then passes out through the side hole 16a of the hollow tube 10a. Accordingly, the metal guide piece 30 retained in the patient's body provides a guiding effect when the new nasogastric tube structure 1a is gradually inserted, and the new nasogastric tube structure 1a is inserted to a designated position, as shown in FIG. 4D. In at least one embodiment of the present disclosure, after the insertion guidance is completed, the metal guide piece 30 can be pulled out of the patient's body, and the new nasogastric tube structure 1a is inserted into the patient's body, as shown in FIG. 4E.

In summary, the nasogastric tube structure disclosed herein can be designed to be separable from the metal guide and the accommodating structure, so that during the process of replacing the nasogastric tube structure disclosed herein, the metal guide can be placed in the patient's body, and only the hollow tube body of the old nasogastric tube structure can be withdrawn from the patient's body. When a new nasogastric tube structure is inserted, the metal guide retained in the patient's body can be used to provide an insertion guidance effect to ensure that the new nasogastric tube is not placed in a wrong position (for example, extending through the mouth or inserted into the trachea). In addition to reducing the difficulty of replacing the nasogastric tube and reducing the time required for replacing the nasogastric tube, thereby increasing the availability of medical staff's time, it can also increase the safety of the patient during the process of replacing the nasogastric tube and reduce the patient's discomfort.

In addition, the through-pipe of the hollow tube is often prone to narrowing or even blockage due to long-term feeding or medication. Therefore, compared with inserting the metal guide into the through-pipe of the hollow tube, the metal guide will be easier to place in the accommodating space of the accommodating structure and take out from the accommodating space, thereby greatly shortening the required length of the metal guide.

The above embodiments are essentially only for auxiliary explanation and are not intended to limit the embodiments of the subject matter of the application or the application or use of such embodiments. In addition, although at least one exemplary embodiment has been proposed in the aforementioned embodiments, it should be understood that there are still a large number of variations in the present disclosure.
