Description

Technical Field

[0001] The invention relates to the field of otolaryngology nursing, in particular to a nasal medicine nursing device for otolaryngology patients. Background Art

[0002] In the clinical care of otolaryngology, the administration of intranasal drugs usually relies on simple spray devices or manual drops. Although these traditional methods can achieve nasal drug delivery to a certain extent, they have the following problems: The liquid medicine of traditional spray devices is usually sprayed into the nasal cavity in a straight line. However, the inner wall of the nasal cavity is not a smooth straight line, but has complex folds and curved areas. Such a structure makes it difficult for the spray to cover the entire nasal cavity, especially the deep nasal concha. This limitation will directly affect the therapeutic effect of the drug, and it is impossible to ensure that the liquid medicine can evenly contact the inner wall of the nasal cavity; In addition, in existing drop or spray devices, the direction of the drug flow is almost uncontrollable and can only rely on natural gravity or a simple spray direction. The shape of the patient's nasal cavity varies from person to person. This fixed direction method causes the drug to easily accumulate in certain areas during delivery, and it cannot effectively reach the lesion site or completely cover the nasal cavity. The lack of targeting makes the treatment inefficient; At the same time, because the spray direction is single, a large amount of liquid medicine may not be effectively absorbed by the nasal mucosa, but directly flows out of the nasal cavity, causing waste. This not only affects the economic efficiency of drug use, but also increases the burden on patients. This is particularly inconvenient for patients who need precise medication. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a nasal medication care device for ENT patients, which solves the problems of limited coverage of the medicine solution, uncontrollable flow direction, insufficient treatment targeting and waste of medicine solution in the prior art.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments.

[0021] Please see attached Figure 1 -Attached Figure 8An embodiment of the present invention provides a nasal medication care device for otolaryngology patients, comprising: a plug rod 1, inside which is installed a folded tube 2, which guides liquid to flow out into the nasal cavity after the plug rod 1 enters the nasal cavity; an adjusting mechanism 4, which is installed at the bottom of the plug rod 1 and is used to drive the folded tube 2 so that the end of the folded tube 2 rotates along the middle of the folded tube 2 as a rotation axis; a bottom tube 21, which is installed at the bottom of the plug rod 1 and is movably connected to the other end of the folded tube 2, and is used to guide liquid into the folded tube 2.

[0022] When in use, the bottom tube 21 is connected to the injection, and then the plug rod 1 is inserted into the patient's nasal cavity. At this time, the syringe is pushed to push the medicine along the bottom tube 21 into the folded tube 2, and finally discharged from the end of the folded tube 2. At this time, the patient's nasal cavity can be medicated, and the folded tube 2 can be driven to rotate by the adjustment mechanism 4, so that the folded tube 2 can rotate 360° in the nasal cavity, thereby achieving the spraying of the medicine on the inner wall of the patient's nasal cavity, thereby increasing the coverage of the medicine in the nasal cavity, ensuring that the medicine can fully contact the folds of the inner wall of the nasal cavity and the surface of the nasal concha, and enhancing the therapeutic effect of the medicine.

[0023] Please refer to the attached Figure 2 -Attached Figure 8 The adjustment mechanism 4 includes a support rod 41, one end of the support rod 41 is fixedly connected to a gear 42, and the other end is fixedly connected to a paddle 43. A gear ring 44 is fixedly connected to the bottom of the outer wall of the folding tube 2, and the gear ring 44 is meshed with the gear 42. The gear ring 44, the gear 42 and the support rod 41 are all installed at the inner bottom of the plug rod 1. The diameter of the gear 42 is twice that of the gear ring 44. A clamping ring 22 is fixedly connected to the bottom of the folding tube 2, and a convex ring 23 is fixedly connected to the top of the bottom tube 21. The convex ring 23 is rotatably connected to the inside of the clamping ring 22. A limit ring 7 is fixedly connected to the top of the outer wall of the folding tube 2, and the limit ring 7 is rotatably connected to the top of the plug rod 1.

[0024] The lever 41 is driven to rotate by toggling the paddle 43, and the gear 42 is driven to rotate by the lever 41. At this time, the gear 42 can drive the gear ring 44 to rotate, and then drive the folding tube 2 to rotate through the gear ring 44, so the purpose of rotating the folding tube 2 is achieved. The diameter of the gear 42 is twice that of the gear ring 44. Therefore, a half-turn of the gear 42 can drive the gear 42 and the gear ring 44 to rotate one circle, thereby reducing the rotation range of the paddle 43 and improving the convenience of operation. At the same time, the top of the folding tube 2 can be limited by the limit ring 7, and the convex ring 23 is installed inside the clamping ring 22. When the folding tube 2 rotates, the clamping ring 22 will be driven to rotate on the outer wall of the convex ring 23. Therefore, the connection between the bottom tube 21 and the folding tube 2 can be achieved while maintaining the freedom of the folding tube 2, and the bottom of the folding tube 2 can also be limited, thereby improving the stability of the folding tube 2 when it rotates.

[0025] Please refer to the attached Figure 5 -Attached Figure 8The outer wall of the support rod 41 is fixedly connected with a card plate 8, a plurality of protrusions 81 are arranged inside the card plate 8, a spring 82 is arranged on one side of the protrusion 81, a card groove 83 is opened on one side of the inner bottom of the plug rod 1, a plurality of recessed parts are arranged on the side wall inside the card groove 83, and the protrusion 81 is pushed by the elastic force of the spring 82 to contact the recessed part.

[0026] By installing the protrusion 81 in the card plate 8, the card plate 8 is connected to the support rod 41. At the same time, a plurality of recesses are set on the inner wall of the slot 83. Therefore, when the card plate 8 rotates with the support rod 41, the protrusion 81 will enter another recess from one recess, and when the protrusion 81 moves out of one recess, the spring 82 will be compressed. When the protrusion 81 enters another recess, the spring 82 pushes the protrusion 81 out so that the protrusion 81 contacts the inner wall of the other recess. At this time, the folding tube 2 can be locked, thereby avoiding the phenomenon of the folding tube 2 rotating independently, thereby improving safety during use.

[0027] Please see attached Figure 1 , Figure 2 and attached Figure 5 An adjusting ring 11 is threadedly connected to the middle of the outer wall of the plug rod 1, a retaining ring 12 is fixedly connected to the top of the outer wall of the adjusting ring 11, and the cross-section of the combination of the adjusting ring 11 and the retaining ring 12 is set to be concave.

[0028] By installing the adjusting ring 11 on the outer wall of the plug rod 1, when the plug rod 1 enters the patient's nasal cavity, the diameter of the adjusting ring 11 is larger than the diameter of the plug rod 1, so the adjusting ring 11 will be stuck in the patient's nostril, thereby preventing the plug rod 1 from continuing to enter the patient's nasal cavity. Therefore, it can be prevented that the plug rod 1 enters the patient's nasal cavity too much and causes discomfort to the patient. After rotating the adjusting ring 11, the position of the adjusting ring 11 on the outer wall of the plug rod 1 can be adjusted, and then the length of the plug rod 1 exposed from the top of the adjusting ring 11 can be adjusted, so as to adjust the length of the plug rod 1 entering the patient's nasal cavity, thereby improving the applicability of the device.

[0029] Please see attached Figure 1 -Attached Figure 7 The inner top of the plug rod 1 is provided with a cavity 5, and the top surface of the outer wall of the plug rod 1 is provided with a through hole 6, which is connected to the cavity 5. A connecting pipe 3 is installed on one side of the inside of the plug rod 1, and the top of the connecting pipe 3 is connected to the cavity 5.

[0030] By connecting the connecting tube 3 with the syringe, the syringe can be pushed to push the medicine into the cavity 5 along the connecting tube 3, and finally spray it out from the through hole 6. At this time, the purpose of applying the medicine can be achieved. When the cleaning agent is pushed into the cavity 5, the purpose of cleaning the nasal cavity can be achieved. Since the connecting tube 3 and the folding tube 2 are two independent pipes, contamination between the two can be avoided. When cleaning the nasal cavity, the waste liquid can be collected through the area formed by the retaining ring 12 and the enclosure between the adjusting ring 11 and the plug rod 1, so that the device can maintain sanitary conditions when in use.

[0031] Please refer to the attached Figure 1 , Figure 2 and Figure 7 The bottom of the bottom tube 21 and the connecting tube 3 are fixedly connected with a clamp ring 9, the outer wall of the clamp ring 9 is threadedly connected with a pressure ring 10, a plurality of openings are arranged at the bottom of the clamp ring 9, and the cross section of the clamp ring 9 is arranged to be trapezoidal.

[0032] By setting an opening at the bottom of the clamp ring 9, when the pressure ring 10 is rotated to move the bottom of the outer wall of the clamp ring 9, the cross-section of the clamp ring 9 is set to a trapezoid, that is, the length of the top of the clamp ring 9 is smaller than the diameter of the bottom of the clamp ring 9. Therefore, when the pressure ring 10 is at the bottom of the clamp ring 9, the opening size of the bottom of the clamp ring 9 will become smaller, thereby clamping the liquid outlet end of the syringe.

[0033] Working principle: When in use, first use the syringe to absorb the liquid medicine, then rotate the pressure ring 10 to move it to the top of the outer wall of the clamp ring 9. Since the bottom of the clamp ring 9 is provided with multiple openings, the bottom of the clamp ring 9 will form a structure of multiple clamping claws. When the pressure ring 10 is located at the top of the outer wall of the clamp ring 9, the multiple clamping claws will be far away from each other. At this time, the liquid outlet end of the syringe can be inserted into the bottom of the clamp ring 9, and then the pressure ring 10 is reversed to move it to the bottom of the outer wall of the clamp ring 9. At this time, the multiple clamp rings 9 will be close to each other, and then the liquid outlet end of the syringe will be clamped, thereby realizing the connection between the device and the syringe; When the syringe is connected with the folded tube 2 and the connecting tube 3, the device can be moved and the plug rod 1 can be inserted into the patient's nasal cavity, and the adjusting ring 11 and the retaining ring 12 are placed at the patient's nostrils. Then, the injection connected with the connecting tube 3 is pressed first, and the medicine can be pushed into the connecting tube 3, and then enter the cavity 5 and finally sprayed out from the through hole 6. At this time, the liquid medicine can be filled into the patient's nasal cavity, and after the injection absorbs the cleaning liquid, the purpose of cleaning the patient's nasal cavity can also be achieved. At the same time, the waste liquid after cleaning flows out along the nasal passage and finally flows into the area formed by the outer retaining between the retaining ring 12 and the adjusting ring 11 and the plug rod 1, thereby realizing the collection of the waste liquid; Then, the injection connected to the bottom tube 21 is pressed, and the liquid medicine inside the syringe can be pushed into the bottom tube 21, and then sprayed out from the top of the folded tube 2. The folded tube 2 is provided with a bend, so it can better adapt to the tortuous path of the nasal cavity. In addition, when the liquid medicine is pushed in and sprayed out from the folded tube 2, the paddle 43 can be turned, and the paddle 43 can be used to drive the support rod 41 to rotate. At this time, the support rod 41 will drive the gear 42 to rotate. When the gear 42 rotates, it can also drive the magnetic ring and the folded tube 2 to rotate. At this time, the bent part of the folded tube 2 can be rotated along the middle part of the folded tube 2. The diameter of the gear 42 is twice that of the gear ring 44. Therefore, after the paddle 43 rotates one circle, it will drive the gear 42 to rotate half a circle, and the gear ring 44 will rotate one circle, thereby driving the bent part of the folded tube 2 to rotate one circle, so that the purpose of using the folded tube 2 to spray the liquid medicine on the inner wall of the nasal cavity can be achieved. When the support rod 41 rotates, it will also drive the card plate 8 to rotate, and the card plate 8 will drive the protrusion 81 to rotate together. At this time, by setting the end of the protrusion 81 that contacts the inner wall of the slot 83 to be hemispherical, and the inner wall of the slot 83 is provided with a plurality of semi-arc-shaped recesses, when the paddle 43 is turned to drive the support rod 41 to rotate, when the protrusion 81 moves out of the recess of the slot 83, the protrusion 81 will enter the interior of the card plate 8 and compress the spring 82. When the protrusion 81 enters from one recess to another, the spring 82 will push the protrusion 81 out, so that it enters the other recess and contacts the inner wall of the other recess. At this time, the folding tube 2 can be locked, thereby avoiding the phenomenon of the folding tube 2 rotating independently, thereby improving the safety during use.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
