Description

Technical Field

[0001] This invention belongs to the field of nasogastric tube technology, specifically relating to a nasogastric tube fixing and adjustment device for nursing care. Background Technology

[0002] Nasogastric feeding is a procedure performed under special circumstances where a feeding tube is inserted into the esophagus through the nasal cavity. The food is first ground into a paste using a grinder. A large syringe is then connected to the large feeding port at the bottom of the feeding tube connector. After a secure connection, the piston is manually pressurized to inject water and food into the patient's stomach. This helps patients who cannot swallow independently by providing them with water and food to maintain metabolism, weight, and nutrition. Nasogastric feeding can irritate the nasopharynx and cause discomfort to the patient. Furthermore, in some patients, confusion or agitation can cause the feeding tube to dislodge.

[0003] Patent CN218923274U discloses a nasogastric tube fixing patch, comprising an upper fixing area and a lower fixing band. The lower fixing band is connected below the upper fixing area. The upper fixing area includes a nasal fixing area, and face fixing areas are provided on both sides of the nasal fixing area. Ventilation holes are evenly distributed on the nasal fixing area and the face fixing area. An oil-absorbing pad is provided at the junction of the face fixing area and the nasal fixing area. The face fixing area is unfolded and pasted onto the cheeks on both sides of the nose. After the upper fixing area is fixed, the lower fixing band is wrapped around the two nasogastric tubes respectively, with the wrapping area of ​​the lower fixing band responsible for wrapping around the lower fixing band. However, the nasogastric tubes are wrapped tightly with the lower fixing band, making it difficult to define and adjust the position of the nasogastric tubes. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-7 This invention provides a technical solution for a nasogastric tube fixing and adjustment device for nursing care.

[0039] A nursing nasogastric tube fixing and adjustment device includes:

[0040] Nose strip 1, one side of nose strip 1 has an adhesive layer, and the other side is fixed with a support member 2, and a fixing shaft 3 is fixed on the support member 2;

[0041] The connecting rod 4 has a first through hole 5 and a second through hole 6 distributed at both ends. The fixed shaft 3 is inserted into the first through hole 5 and can rotate relative to the first through hole 5.

[0042] Adjustment shaft 7 passes through the first through hole 5 and can move up and down and rotate relative to the first through hole 5. The lower end of adjustment shaft 7 is fixed to the nasogastric tube.

[0043] The limiting device is used to limit the relative position of the connecting rod 4 and the fixed shaft 3, and also to limit the relative position of the adjusting shaft 7 and the connecting rod 4.

[0044] When the nasogastric tube fixing and adjusting device is needed to fix the nasogastric tube, first attach the nasal strip 1 to the nose through the adhesive layer, then fit the first through hole 5 of the connecting rod 4 onto the fixing shaft 3, then rotate the connecting rod 4 to a suitable angle, then pass the adjusting shaft 7 through the second through hole 6 on the connecting rod 4, and fix the lower end of the adjusting shaft 7 to the nasogastric tube, then adjust the up and down position and angle of the adjusting shaft 7 until the nasogastric tube is adjusted to a suitable position, and then use the limiting device to limit the relative position of the connecting rod 4 and the fixing shaft 3, and at the same time limit the relative position of the adjusting shaft 7 and the connecting rod 4, thereby adjusting the nasogastric tube to a suitable position.

[0045] By setting multiple adjustments, the vertical position and angle of the nasogastric tube can be adjusted, making it easy to guide the tube out of the nostril sideways without the tube hanging in front of the mouth. Then, the extended part of the nasogastric tube is fixed to the face, while preventing the tube from shaking randomly.

[0046] The limiting device includes:

[0047] The pressing rod 8 and the connecting rod 4 are provided with a receiving cavity 9. The receiving cavity 9 has pressing holes 10 on both sides opposite to each other. The pressing rod 8 passes through the two pressing holes 10 in sequence. A fixing ring 12 is fixed on the pressing rod 8.

[0048] The first hinge rod 13 has one end hinged to the fixed ring 12 and the other end hinged to the first limiting rod 14. The connecting rod 4 has a first connecting groove 15 inside, which connects the first through hole 5 and the receiving cavity 9. The first limiting rod 14 is inserted into the first connecting groove 15. The end of the first limiting rod 14 away from the first hinge rod 13 is set as the first limiting end 16. The fixed shaft 3 has a plurality of first limiting grooves 17, which are evenly distributed around the axis of the fixed shaft 3. When the first limiting end 16 is inserted into any one of the first limiting grooves 17, the position between the connecting rod 4 and the fixed shaft 3 is restricted.

[0049] The second hinge rod 18 has one end hinged to the fixed ring 12 and the other end hinged to the second limiting rod 19. The connecting rod 4 has a second connecting groove 20 inside, which connects the second through hole 6 and the receiving cavity 9. The second limiting rod 19 is inserted into the second connecting groove 20. The end of the second limiting rod 19 away from the second hinge rod 18 is set as the second limiting end 21. The adjusting shaft 7 has a set of second limiting grooves 22. The set of second limiting grooves 22 includes several second limiting grooves 22 distributed around the circumference of the adjusting shaft 7. When the second limiting end 21 is inserted into any second limiting groove 22, the position between the connecting rod 4 and the adjusting shaft 7 is restricted. Several sets of second limiting grooves 22 are provided, and several sets of second limiting grooves 22 are arranged sequentially along the axial direction of the adjusting shaft 7.

[0050] Pressing the pressing lever 8 moves the first limiting lever 14 and the second limiting lever 19, thus controlling whether the connecting rod 4 and the adjusting shaft 7 are limited. A single pressing lever 8 can move the first limiting lever 14 and the second limiting lever 19, which is very convenient and results in a simpler and more compact structure.

[0051] To prevent the pressing rod 8 from moving arbitrarily, the limiting device also includes a limiting spring 23. The limiting spring 23 is sleeved on the pressing rod 8 and is located between the fixing ring 12 and the inner wall of the receiving cavity 9. When the limiting spring 23 is in its original length state, the first limiting end 16 is inserted into the first limiting groove 17, and at the same time, the second limiting end 21 is inserted into the second limiting groove 22. Thus, when it is necessary to adjust the position of the connecting rod 4 or the adjusting shaft 7, pressing the pressing rod 8 requires overcoming the rebound force of the limiting spring 23, and requires active adjustment to prevent the pressing rod 8 from moving arbitrarily.

[0052] One end of the pressing rod 8 is designated as a pressing end 24, which is located outside the connecting rod 4. The pressing end 24 includes a first state, a second state, and a third state.

[0053] In the first state, the limit spring 23 is in its original length.

[0054] In the second state, the second limiting end 21 leaves the second limiting groove 22, while the first limiting end 16 remains inserted into the first limiting groove 17.

[0055] In the third state, the second limiting end 21 leaves the second limiting groove 22, and the first limiting end 16 leaves the first limiting groove 17.

[0056] The advantage of the above three state settings is that the connecting rod 4 and the adjusting shaft 7 can be adjusted independently. For example, when installing the connecting rod 4, first press the pressing end 24 of the pressing rod 8. The pressing end 24 is in the third state. Put the first through hole 5 of the connecting rod 4 onto the fixed shaft 3. Then rotate the connecting rod 4 to a suitable angle. Then reduce the force applied to the pressing end 24. The limit spring 23 rebounds and the pressing end 24 is in the second state. At this time, the first limit end 16 is inserted into the corresponding second limit. Then the adjusting shaft 7 can be inserted into the second through hole 6 to adjust the height and angle of the adjusting shaft 7. After adjusting to a suitable position, release the pressing end 24. The pressing end 24 is in the third state due to the rebound force of the limit spring 23. At this time, the second limit end 21 is inserted into the corresponding second limit groove 22 to limit the position of the adjusting shaft 7.

[0057] By setting three states, the positions of the connecting rod 4 and the adjusting shaft 7 can be adjusted individually, making installation more convenient.

[0058] The following is one method of fixing the nasogastric tube. The adjusting shaft 7 is provided with an adjusting groove 25, and an adjusting rod 26 is inserted into the adjusting groove 25. An adjusting half-ring 27 is fixed at the lower end of the adjusting rod 26. A fixing bracket 28 is also provided on the outer wall of the adjusting shaft 7. A fixing half-ring 29 is fixed on the fixing bracket 28. The fixing half-ring 29 is located below the adjusting half-ring 27. The nasogastric tube is located between the fixing half-ring 29 and the adjusting half-ring 27.

[0059] When the nasogastric tube needs to be fixed, first move the adjusting half-ring 27 upward, then move the nasogastric tube between the adjusting half-ring 27 and the fixed half-ring 29, and then move the adjusting half-ring 27 downward to restrict the nasogastric tube between the adjusting half-ring 27 and the fixed half-ring 29.

[0060] To further secure the nasogastric tube, the fixing and adjusting device also includes a tightening strap 30. One end of the tightening strap 30 is fixedly connected to one end of the adjusting half-ring 27, and the other end passes around the fixing half-ring 29 and is fixed to the other end of the adjusting half-ring 27. The tightening strap 30 connects the adjusting half-ring 27 and the fixing half-ring 29 together, thereby better restricting the position of the nasogastric tube. The tightening strap 30 is provided with a tightening adhesive layer, and the tightening strap 30 is fixed to the adjusting half-ring 27 and the fixing half-ring 29 by the tightening adhesive layer.

[0061] The inner wall of the adjusting half-ring 27 is fixed with an adjusting adhesive layer 31, and the inner wall of the fixing half-ring 29 is fixed with a fixing adhesive layer 32. The adjusting adhesive layer 31 and the fixing adhesive layer 32 can adhere to the nasogastric tube and better fix the nasogastric tube.

[0062] Two support pieces 2 are fixed on the nasal strip 1, which can limit the two nasal feeding tubes, or select one at a time.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
