Description

Technical Field

[0001] The present invention relates to a nasal catheter with a guide wall. More specifically, the nasal catheter with a guide wall has a guide wall portion formed on one side of the inner side of the front end portion of the tube body, thereby spraying a liquid medicine or a cleaning liquid in a direction parallel to the nasal passage to reduce the pressure on the nasal septum. Background Art

[0002] Usually, the nasal catheter is combined with a nasal washer, which is connected to one end of a shaft for spraying liquid medicine or cleaning liquid, and the purulent mucus or solidified secretions caused by inflammation inside the nose such as in the nasal cavity or paranasal cavity are cleaned, disinfected or sucked by suction.

[0003] The nasal cavity is the empty space inside the nose, and inside it is a mucous membrane formed by villi that vibrate only in one direction. The surface of the villi is coated with mucus for filtering harmful substances such as dust, viruses, and pollen in the air. And, since the substances filtered by the mucous membrane move from the nose through the throat to the stomach and intestines together with the mucus, only purified air is delivered to the lungs.

[0004] Currently, with the development of industry and urbanization, modern people are breathing polluted air containing industrial waste generated by automobile exhaust and industrial sites, harmful air containing indoor dust, mites, pollen, pet hair that cause allergies, and various viruses contained in the air, such as coronavirus, adenovirus, rhinovirus and influenza virus, which are the main causes of colds.

[0005] As described above, as the harmful air inhaled through breathing continuously irritates the mucous membrane in the nasal cavity, not only the function and normal defense ability of the mucous membrane are reduced, but also inflammatory rhinitis will be caused. Furthermore, in the case where the harmful air contains harmful viruses, respiratory diseases will be caused.

[0006] Therefore, in order to clean the nasal cavity and oral cavity with medicine and remove harmful substances attached to the mucous membrane, medical institutions that treat respiratory diseases use nasal washers and nasal aspirators connected to nasal catheters.

[0007] However, this prior art nasal catheter has a problem of causing bleeding due to pressure applied toward the nasal septum when inserted into the nasal cavity and spraying a liquid medicine or a cleaning solution.

[0010] Patent Document 1: Korean Patent No. 20-0481301 (granted on November 19, 2012) Summary of the invention

[0011] In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a nasal catheter with a guide wall of a novel structure. Since the guide wall portion is formed on one side of the inner portion of the front end portion of the tube body, a liquid medicine or a cleaning liquid can be sprayed in a direction parallel to the nasal passage to reduce the pressure on the nasal septum.

[0012] Furthermore, another object of the present invention is to provide a nasal catheter having a guide wall formed therein, which can reduce the pressure on the nasal septum even when the front end portion of the tube body is located in the sine (Sin) direction based on the nasal septum.

[0013] Furthermore, another object of the present invention is to provide a nasal catheter having a guide wall formed therein, wherein an identification portion is formed to determine the position of a guide wall portion formed inside a front end portion of a tube body.

[0014] Furthermore, another object of the present invention is to provide a nasal catheter having a guide wall formed thereon, which can reduce the pressure on the nasal septum when connected to a nasal aspirator to perform suction by negative pressure.

[0015] In order to achieve the above-mentioned purpose, the nasal catheter with a guide wall provided by the present invention comprises: a tube body connected to one end of the shaft of a device for spraying a liquid medicine or a cleaning liquid and inserted into the nasal cavity; and a guide wall portion, which is inclined at one side inside the front end portion of the tube body so that the liquid medicine or the cleaning liquid is sprayed in an eccentric direction.

[0016] According to the nasal catheter formed with a guide wall in an embodiment of the present invention, when the tube body is located in a sinusoidal direction based on the nasal septum, the guide wall portion can allow the drug solution or cleaning solution to be sprayed in a direction parallel to the nasal passage.

[0017] According to the nasal catheter with a guide wall formed in an embodiment of the present invention, the cross-section of the guide wall portion can be formed into one of a triangle with a slope increasing toward the front end of the tube body, a triangle with a concave side, a triangle with a convex side, and a quadrilateral.

[0018] The nasal catheter with a guide wall according to an embodiment of the present invention may include an identification portion formed on the outer peripheral surface of the rear end portion of the tube body in a manner corresponding to a straight line in a direction facing the guide wall portion, so as to determine the position of the guide wall portion.

[0019] The nasal catheter with a guide wall of the present invention has the following advantages: since the guide wall is formed on one side of the inner side of the front end of the tube body, a medicine or a cleaning solution can be sprayed in a direction parallel to the nasal passage to reduce the pressure on the nasal septum, thereby preventing nasal septum bleeding.

[0020] Furthermore, even if the front end portion of the tube body is located in a sinusoidal direction based on the nasal septum due to the structure of the nasal cavity, the pressure exerted on the nasal septum by the drug solution or cleaning solution sprayed through the guide wall portion can be reduced.

[0021] Furthermore, the nasal catheter with a guide wall of the present invention has an identification portion formed on the outer periphery of the rear end portion of the tube body, so that the position of the guide wall portion formed on the inner side of the front end portion of the tube body can be determined, thereby reducing the tediousness of confirming the position of the guide wall portion when the tube body is inserted into the nasal cavity.

[0022] Furthermore, in addition to the spray, the nasal cannula formed with the guide wall of the present invention can reduce the pressure on the nasal septum even when connected to a nasal aspirator to aspirate snot by negative pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Hereinafter, a nasal catheter with a guide wall formed thereon according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0040] Figure 1 This is a perspective view showing the appearance of a nasal catheter with a guide wall formed thereon according to an embodiment of the present invention. Figure 2 FIG. 2 is a cross-sectional view showing a nasal catheter having a guide wall formed therein according to an embodiment of the present invention. Figure 3 This is a conceptual illustration of a nasal catheter having a guide wall formed therein according to an embodiment of the present invention. Figure 4 The figures are illustrative diagrams showing various shapes of the guide wall portion of the nasal catheter formed with the guide wall according to the embodiment of the present invention.

[0041] like Figure 1 As shown, the nasal catheter 10 with a guide wall according to the embodiment of the present invention includes a tube body 100 and a guide wall portion 200 .

[0042] In more detail, Figure 1 and Figure 2 As shown, the nasal catheter 10 with a guide wall according to an embodiment of the present invention comprises: a tube body 100, which is connected to one end of a shaft 11 of a device for spraying a liquid medicine or a cleaning liquid and is inserted into the nasal cavity; and a guide wall portion 200, which is inclined at one side of the inner portion of the front end portion of the tube body so that the liquid medicine or the cleaning liquid is sprayed in an eccentric direction.

[0043] Furthermore, the tube body 100 of the nasal catheter 10 with a guide wall formed in the embodiment of the present invention is connected to one end of the shaft of the nasal aspirator, and harmful substances, purulent mucus or solidified secretions caused by inflammation in the nasal cavity can be aspirated. Therefore, the nasal catheter 10 with a guide wall formed in the embodiment of the present invention can be separately or selectively connected to a device for spraying a liquid medicine or a cleaning liquid and a suction device for aspirating the inside of the nasal cavity.

[0044] Furthermore, for the sake of convenience in describing the technology of the present invention, the specific contents of the nasal aspirator suction are described with reference to the description of spraying through the nasal spray device. Moreover, in the drawings of the specification, since the suction principle is also applicable to the spraying principle, the description of this will be omitted.

[0045] Reference Figure 1 and Figure 2The tube body 100 is a conduit with both sides open, and has flexibility to be inserted into the nasal cavity. Moreover, it is connected to one end of the shaft 11, and the shaft 11 is connected to a device for spraying a liquid medicine or a cleaning solution.

[0046] The tube body 100 further includes a conical portion 110 and a passage 120 .

[0047] The diameter of the conical portion 110 gradually increases from the front end portion toward the rear end portion, and an extension portion connected to one end of the shaft 11 is formed.

[0048] That is, the diameter of the conical portion 110 is relatively small so that the front end can be inserted into the nasal cavity, and the diameter gradually increases toward the rear end to form a shape that prevents excessive insertion into the nasal cavity. Moreover, preferably, it can have a predetermined elastic force to maintain its shape inside the nasal cavity.

[0049] The passage 120 allows the front end and the rear end of the cone portion 110 and the extension portion to communicate with each other, so that the chemical liquid or the cleaning liquid moving from the shaft 11 is sprayed through the front end of the cone portion 110 .

[0050] Reference Figure 2 and Figure 3 The guide wall portion 200 is obliquely formed on one side of the inner portion of the front end portion of the tube body 100, so that the drug solution or the cleaning liquid can be sprayed in an eccentric direction.

[0051] For example, during the process of the catheter entering the nasal cavity, the tube body 100 cannot be adjusted according to the shape of the tube body 100 because the structure of the nasal cavity is gradually narrowed. Figure 3 Enter as shown in part (a). So, Figure 3 As shown in part (b) of FIG. 1 , the conical portion 110 having a narrowed front end portion allows the pipe body 100 formed thereby to enter obliquely.

[0052] In this case, when the drug solution or the cleaning solution is sprayed, the suction direction and the spray direction of the catheter are usually toward the nasal septum 12. Therefore, when pressure is applied to the place where bleeding often occurs, the nasal septum 12 may cause nose bleeding.

[0053] In order to improve such a problem, the conical portion 110 of the present invention has a guide wall portion 200 formed inside the front end passage 120 .

[0054] Like this, Figure 2 and Figure 3 As shown in part (b) of the drawing, when the tube body 100 is located in a sinusoidal direction based on the nasal septum 12, the guide wall portion 200 allows the drug solution or cleaning solution to be sprayed in a direction parallel to the nasal passage.

[0055] For example, to clean the inside of the nose, the tube body 100 of the present invention can be inserted into the nasal cavity so as to be located in a sinusoidal direction based on the nasal septum 12. Then, the medicine or cleaning solution flows into the passage 120 through the shaft 11 and is ejected through the front end of the cone 110.

[0056] In this case, if Figure 3 As shown in part (b), since the liquid medicine or cleaning solution is discharged and sprayed in an eccentric direction through the guide wall portion 200, it moves in a parallel direction to the nasal passage forming the inside of the nasal cavity. As a result, as the pressure on the nasal septum 12 is reduced, tissue damage can be reduced, thereby preventing bleeding.

[0057] Furthermore, in addition to spraying liquid medicine or cleaning solution, when suctioning harmful substances that flow into the nasal cavity, purulent mucus or solidified secretions caused by inflammation, suction can be performed in a direction parallel to the nasal passage, thereby preventing the nasal septum 12 from being damaged.

[0058] And, if Figure 4 As shown, in the nasal catheter 10 with a guide wall formed in the embodiment of the present invention, the cross-section of the guide wall portion 200 is preferably a triangle with one side slope increasing toward the front end of the above-mentioned tube body 100, a triangle with one side concave, a triangle with one side convex, and a quadrilateral.

[0059] That is, when spraying through the front end of the cone 110, the guide wall 200 occupies the space of the radius in the inner diameter of the circle to discharge the liquid medicine or cleaning solution moving along the inside of the passage 120 in an eccentric direction. Thus, the pressure on the nasal septum 12 can be reduced by spraying the liquid medicine or cleaning solution in a direction parallel to the nasal passage.

[0060] On the other hand, Figure 1 and Figure 2 As shown, the nasal catheter 10 formed with a guide wall according to the embodiment of the present invention may include an identification portion 300 .

[0061] The identification portion 300 is formed on the outer peripheral surface of the rear end portion of the tube body 100 in a manner corresponding to a straight line in a direction facing the guide wall portion 200 , and can be used to determine the position of the guide wall portion 200 .

[0062] For example, when inserting the tube body 100 into the nasal cavity, there is a cumbersome problem that the portion where the guide wall portion 200 is formed must be confirmed in order to position the front end of the cone portion 100 where the guide wall portion 200 is formed at the nasal septum 12. In order to eliminate this cumbersome problem, the front end of the cone portion 100 can be inserted into the nasal cavity by confirming the identification portion 300.

[0063] In this case, preferably, the identification portion 300 is formed to protrude from the outer peripheral surface of the rear end portion of the cone portion 110, or may be expressed in a color different from the color of the cone portion 110. Moreover, more preferably, the identification portion 300 may also be formed on the outer peripheral surface of the extension portion constituted by the passage 120 extending from the rear end portion of the cone portion 110.

[0064] As described above, in the specific description of the present invention, although the preferred embodiment of the present invention is described, this is only an illustrative description of the preferred embodiment of the present invention and does not limit the present invention. Moreover, ordinary technicians in the technical field to which the present invention belongs can make various modifications and imitations without departing from the scope of the technical concept of the present invention.

[0065] Therefore, the protection scope of the present invention is not limited to the above-mentioned embodiments, and can be implemented by various embodiments within the scope of the invention. Moreover, all modifications made by ordinary technicians in the technical field to which the present invention belongs without departing from the main purpose of the present invention within the scope of the invention are within the scope of the invention.
