Description

[Technical Field]

[0001] The present invention relates to an instrument for suctioning mucus, and more particularly to a nasal suction device with a function to prevent backflow of mucus and an apparatus having the nasal suction device. [Background technology]

[0002] Nasal suction devices for suctioning mucus are primarily used by people who have difficulty or are unable to blow their noses, such as infants. When in use, they must be connected to an air extraction device, which uses external force to suck out mucus from the nasal cavity and temporarily store it in a bottle. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional nasal suction devices have the above-mentioned functions, but because the flow path inside the bottle is close to the negative pressure suction tube, it has long been a problem that the mucus inside the bottle flows back into the negative pressure suction tube.

[0004] Therefore, the present inventors believed that the above drawbacks could be improved, and after extensive research, they came up with the present invention, which effectively improves the above issues through rational design.

[0005] The present invention has been made in consideration of these circumstances, and its purpose is to provide a nasal suction device that has a function to prevent backflow of nasal mucus inside the bottle, and an apparatus that has a nasal suction device. [Means for solving the problem]

[0006] In order to solve the above problems, the nasal suction device of the present invention adopts the following measures. a liquid extraction tube having a gas flow path and a liquid extraction tube disposed within the cover, the liquid extraction tube being inserted into the internal space and having one end forming a liquid inlet in the cover, the liquid extraction tube penetrating the gas flow path and having the other end formed with a liquid outlet spaced apart from the cover, the gas flow path being located between the air extraction part and the liquid outlet; and a partition section disposed within the internal space and partially sealing the gas flow path, the partially sealed portion of the gas flow path being adjacent to the air extraction part and the remaining unsealed portion of the gas flow path being distant from the air extraction part, the air extraction part being in communication with the liquid outlet space via the remaining unsealed portion of the gas flow path.

[0007] In order to solve the above-mentioned problems and achieve the above-mentioned objects, another aspect of the present invention is an apparatus having a nasal suction device, which comprises an air extraction device and the above-mentioned nasal suction device, the air extraction part of which is connected so as to be in communication with the air extraction device. [Effects of the Invention]

[0008] The present invention is configured as described above and therefore has the following advantages. The additional partition partially blocks the gas flow path, and the only gas flow path that connects the cover inside the nasal suction device to the storage bottle can be blocked or separated by the partition so that direct communication is not possible, which has the effect of reliably preventing the mucus in the bottle from flowing back out of the suction tube.

[0009] At least the following points will become clear from the description and drawings to be described later. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the invention according to the scope of the utility model claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0012] The nasal suction device and the device with the nasal suction device of the present invention are used by people who have difficulty or are unable to blow their noses by themselves. When used, the nasal suction device must be connected to an air extraction device, and the negative pressure provided by the air extraction device will suck out the mucus from the nasal cavity and temporarily store it in a bottle.

[0013] The nasal suction device of the present invention includes a nasal suction device 100a and a nasal suction device 100b, which are connected to an air extraction device so as to communicate with each other. The nasal suction device 100a and the nasal suction device 100b suck mucus by the negative pressure provided by the air extraction device (see Figures 1 and 11).

[0014] The first embodiment of the nasal cavity suction device 100a according to the present invention comprises a storage bottle 1, a cover 2a, and a partition part 3 (see Figs. 1 to 4). Each of these will be described below.

[0015] The storage bottle 1 is used to temporarily store the aspirated snot, and has a mouth 111 at one end. The bottle body of the storage bottle 1 may further have a narrowed portion 11 formed at the mouth 111.

[0016] The cover 2a is fitted to the narrowed portion 11 of the storage bottle 1 to correspond to the opening 111, and the fitted nasal suction device 100a has an internal space Z between the cover 2a and the storage bottle 1. An air extraction port 251 is formed in the cover 2a, and a hollow liquid extraction tube 26 is provided within the cover 2a. The cover 2a has a liquid inlet 261, and one end of the liquid extraction tube 26 is connected to the cover 2a to correspond to the liquid inlet 261. The liquid extraction tube 26 extends from the connected portion toward the internal space Z and extends beyond the air extraction port 251. A liquid outlet 262 spaced from the cover 2a is formed at the extending end (free end) of the liquid extraction tube 26. The air extraction port 251 and the liquid outlet 262 are connected to each other and jointly define the gas flow path 2135. When the air extraction device provides negative pressure to the nasal suction device 100a, the negative pressure causes the user's mucus to be sucked through the air extraction part 251, the liquid outlet 262 of the liquid extraction tube 26, and the liquid inlet 261, and the mucus is introduced into the storage bottle 1 by the liquid extraction tube 26 and stored therein.

[0017] In this embodiment, the cover 2a has a lid body 21 and a suction head 22 that are in communication with each other (details will be described later).

[0018] The lid body 21 includes an annular portion 211 and a cover plate 213. The annular portion 211 has two openings facing each other, and the cover plate 213 is connected to one opening of the annular portion 211 and is defined so as to form an outlet by partially closing it. The cover plate 213 has an inner surface 2131 and an outer surface 2132 facing each other.

[0019] The suction head 22 is connected to the cover plate 213 so that a position corresponding to the gas flow path 2135 corresponds to the outlet from the outer surface 2132. As shown in the figure, the suction head 22 has a three-dimensional cone shape and a surrounding inner wall 222, and the air extraction port 251 is opened on one side of the suction head 22. A center C is defined in the cover 21, and the outlet and the center C are installed with a gap between them. The suction head 22 is connected to the cover plate 213 so as to be offset from the center C, and the suction head 22 is installed so as to be offset relative to the cover 21 (see Figures 2, 4, and 5).

[0020] Furthermore, the suction head 22 may further include a suction tube 25, which is connected to the suction head 22 so as to correspond to the air extraction portion 251. It should be noted here that the suction head 22 is connected to the cover plate 213 so as to be deflected, and the suction tube 25 is installed so as to overlap the outer surface 2132 of the cover plate 213, so that the suction tube 25 is supported by the cover body 21, which has the effect of making it less likely to break even when subjected to external forces such as a collision (see FIG. 2).

[0021] It should be noted that in this embodiment, the partition 3 is not limited to being provided inside the cover 2a, but may also be selectively provided inside the storage bottle 1 as long as it is located within the internal space Z. The partition 3 according to this embodiment will be described taking an example in which it is provided inside the cover 2a.

[0022] In this embodiment, the suction head 22 is connected to the cover plate 213 in a deflectable manner, and therefore, a connecting portion other than the gas flow path 2135 is formed on the inner surface 2131 of the cover plate 213 (not shown), as shown in Figures 3 to 5. In this manner, the partition 3 can be connected to the connecting portion on the inner surface 2131 of the cover plate 213, and the connecting method can be adhesively bonded to each other (for example, one surface of the partition 3 is attached and adhesively bonded to the connecting portion on the inner surface 2131), or they can be detachably engaged with each other. Of course, the partition 3 can also be attached to the cover plate 213 by utilizing the size design between the annular portion 211 and the partition 3 depending on the manufacturing technology design.

[0023] As shown in FIGS. 6 and 7, a locking structure S is added between the partition 3 and the cover plate 213 to detachably engage them. The locking structure S includes an engaging member S1 and a recess S2 that can be engaged with each other to secure them together. The recess S2 is a recessed groove or may be a through-opening. The recess S2 is recessed from the inner surface 2131 of the cover plate 213 toward the outer surface 2132, and the engaging member S1 is protruded from one surface of the partition 3 to correspond to the recess S2 (see FIG. 6). As shown in FIG. 7, contrary to what is shown in FIG. 6, the recess S2 is recessed from one surface of the partition 3 toward the other surface (or is recessed until it penetrates), and the engaging member S1 is protruded from the inner surface 2131 of the cover plate 213 to correspond to the recess S2.

[0024] 8, the suction tube 25 of the nasal suction device 100a of the present invention is connected to the air extraction device (for example, the manual air pump 800 shown in the figure) via the connecting tube 5. When suctioning nasal mucus, the position of the liquid inlet 261 of the suction head 22 is aligned with the nasal cavity, and then the air extraction device is operated to extract air so as to create negative pressure through the suction tube 25. The nasal suction device 100a will then suck the nasal mucus from the nasal cavity through the suction tube 25, the opening of the gas flow path 2135, and the liquid extraction tube 26. The nasal mucus will then flow out from the liquid outlet 262 and be temporarily stored in the storage bottle 1.

[0025] As a result, after the partition 3 is installed inside the cover 2a, the gas flow path 2135 is partially blocked. In particular, as shown in the cross-sectional view of Figure 8, by blocking the gas flow path 2135 corresponding to one side of the liquid extraction tube 26 facing the air extraction portion 251, an opening is formed on the other side of the liquid extraction tube 26 facing the air extraction portion 251. In this way, when snot is stored in the storage bottle 1, the snot is sucked by negative pressure through the air extraction path of the gas flow path 2135 and moves away from the air extraction path, preventing backflow into the air extraction portion 251 and preventing contamination.

[0026] It should be noted that the air extraction device may be a manual air pump 800 as shown in FIGS. 1 and 8, or an electric air pump M as shown in FIG. 9, but the present invention is not limited thereto.

[0027] 1 and 8, manual air pump 800 includes pump 8 and operating handle 9. Pump 8 includes a cylinder 81 and a cover 83 that are assembled together. Cylinder 81 has an air vent line 812, and cover 83 has a handle 832 that extends integrally therefrom. Operating handle 9 is inserted into pump 8 so as to be extendable and retractable, and is connected to piston 91 and return spring 92 that elastically supports the piston 91 and cover 83. In operation, a user pulls operating handle 9 to drive piston 91 to move within pump 8. As the piston 91 moves, it elastically compresses return spring 92, causing air to be extracted by creating negative pressure through air vent line 812. After releasing the external force acting on operating handle 9, piston 91 can be returned to its original position by return spring 92.

[0028] 3 and 4, the partition 3 is disposed inside the cover 21, is attached to the inner surface 2131 of the cover plate 213, and partially blocks the gas flow path 2135. The portion not blocked by the partition 3 defines an opening 31. The opening 31 is located on the other side of the liquid extraction tube 26 and is spaced apart from the air extraction port 251. The opening 31 may be an outlet 311 formed in the partition 3, or may be formed in the unblocked portion of the partition 3 that has a semicircular outer contour. The present invention does not limit the shape or configuration of the opening 31, as long as the air extraction port 251 and the liquid extraction tube 26 are in communication with each other.

[0029] 3 to 5, to further enhance the effect of preventing backflow of mucus within the bottle, the length of the liquid extraction tube 26 inserted into the storage bottle 1 may be extended, and the distance between the liquid outlet 262 of the liquid extraction tube 26 and the air extraction portion 251 may be increased to extend the air extraction path, thereby strengthening the effect of preventing backflow of mucus. The lid 21 of the cover 2a has a cap mouth 214, and the opening 31 is located close to the cap mouth 214. The liquid extraction tube 26 protrudes a certain distance from the cap mouth 214 and is inserted into the storage bottle 1. The cover 2a may be combined with the narrowed portion 11 of the storage bottle 1 by the cap mouth 214 to correspond to the mouth 111.

[0030] 3 to 5, the partition unit 3 is provided with a retraction section 32 for retracting the liquid extraction tube 26, and the retraction section 32 avoids the liquid extraction tube 26. Specifically, the retraction section 32 may be a C-shaped notch as shown in the figures, and may be connected to the opening 31, or may be a surrounding through-hole (not shown). In this way, the liquid extraction tube 26, which is positioned so as to correspond to the central positions of the suction head 22 and the gas flow path 2135, can be installed in the notch or through-hole so as to be retracted.

[0031] In this specification, since the suction head 22 is connected to the cover plate 213 in a biased manner, the liquid extraction tube 26 connected to the suction head 22 also follows and deviates from the center C of the cover 21, as shown in FIG. 5 . Relatively, the partition 3 must also be installed in a biased manner, and thus the opening 31 and the retracted portion 32 of the partition 3 also follow and deviate from the center C of the cover 21. This makes it less likely that the user will install the partition 3 in the wrong direction. If the installation direction is incorrect, the liquid extraction tube 26 and the retracted portion 32 will avoid each other, making it impossible to install the partition 3. In other words, the partition 3, which is installed in a biased manner, serves as a foolproof means in this embodiment.

[0032] As shown in Figures 3 to 5, the partition 3 and the cover 21 are designed to fit the partition 3 in only one direction—vertically or linearly—to the cover 21. Because the partition 3 is installed inside the cover 21 and the retraction portion 32 of the partition 3 is bonded to the outer wall of the liquid extraction tube 26, if the partition 3 cannot be retracted linearly along the liquid extraction tube 26 to remove the cover 2a and clean it, if the retraction portion 32 of the partition 3 interferes with the outer wall of the liquid extraction tube 26, making it difficult to remove the partition 3 from the cover 2a. Therefore, by extending the pull rod 34 from the partition 3 and aligning the pull rod 34 and the liquid extraction tube 26 in parallel with each other (e.g., parallel to each other), the user can simply grasp the pull rod 34 and pull it linearly backward to remove the partition 3 from the cover 2a along the liquid extraction tube 26. Specifically, the partition 3 has a first plate 36a, and the pull rod 34 protrudes integrally from the first plate 36a. Preferably, as shown in Fig. 5, the pull rod 34 is located between the retracted portion 32 and the outer peripheral edge of the partition 3, so that the position is close to the center of the first plate 36a, thereby achieving a labor-saving effect, and it is also preferable that the retracted portion 32, the pull rod 34, and the air extraction portion 251 are all arranged in a straight line on the same plane.

[0033] 10 , the divider 3 according to this embodiment is provided inside the storage bottle 1. For example, a support structure 12 is provided around the inner wall of the storage bottle 1, and the divider 3 is placed inside the storage bottle 1 so as to be positioned relative to the support structure 12.

[0034] 11 and 12 show a second embodiment of a nasal suction device 100b according to the present invention, which is substantially the same as the first embodiment, except that a cover 2b is different from the cover 2a of the first embodiment.

[0035] In this embodiment, the lid body 21 and suction head 22 of the cover 2b are arranged coaxially, the centers of the lid body 21 and suction head 22 are aligned with each other, and the lid body 21 has only an annular portion 211. The annular portion 211 has two openings facing each other and two horizontal bars, one above the other. The suction head 22 is connected to one horizontal bar corresponding to one of the openings and protrudes integrally in one direction. The suction head 22 has a surrounding inner wall 222.

[0036] In addition, a support part 255 is formed in the suction head 22 to connect the partition part 3, and the suction tube 25 has an outer part 256 that is exposed to the outside of the cover 2b. The support part 255 is protruded into the suction head 22, and as shown in Figure 11, the support part 255 protrudes a certain length from the inner wall 222. In this way, the partition part 3 can be connected to the support part 255 by the connecting method according to the present invention.

[0037] Furthermore, since the cover 21 and the suction head 22 are arranged coaxially, the liquid extraction tube 26 and the retraction section 33 of the partition 3 are located coaxially at the center C of the cover 21, allowing the partition 3 to rotate relative to the cover 2b. To prevent the partition 3 from rotating relative to the cover 2b, a stop 27 and a limiting section 35 are provided at adjacent positions between the partition 3 and the cover 21, respectively. The stop 27 and the limiting section 35 are coupled to each other so as to limit their positions, preventing the partition 3 from rotating relative to the cover 2b. To further achieve a foolproof effect, the opening 31 of the partition 3 needs to be separated from the air extraction section 251.

[0038] Specifically, the stop portion 27 may be a bump that is protruded from the lid body 21, and the limiting portion 35 may be a scrap edge that is opened in the partition portion 3 and corresponds to the stop portion 27, with the scrap edge (limiting portion 35) being formed in a concave shape relative to the outer peripheral edge 37 of the partition portion 3 so as to correspond to the shape of the bump (stop portion 27).

[0039] 11, a screw structure T may be further provided between the cover 2b and the storage bottle 1, so that the cover 2b can be removably screwed onto the storage bottle 1. It should be noted that in the first embodiment of the nasal suction device 100a of the present invention, the cover 2a can be removably screwed onto the storage bottle 1.

[0040] 13 and 14 show a third embodiment of the nasal suction device 100b according to the present invention, which is substantially the same as the second embodiment, except for the partial structure of the cover 2b and the partial structure of the partition 3. It should be noted that within the scope of the various embodiments of the present invention, the air extraction part 251 and the suction tube 25 may be modified to be installed on one side of the storage bottle 1, and as long as the distance between the air extraction part 251 and the liquid outlet 262 can be maintained and the gas flow path 2135 can be formed, all of these are within the scope of the present invention.

[0041] The partition 3 is disposed inside the cover 2b to correspond to the cover 2b, and partially blocks the gas flow path 2221 of the cover 2b. A non-sealed portion N is formed between the inner wall 222 and the outer peripheral edge 37 of the cover 2b, as shown in FIG. 13 . The non-sealed portion N corresponds to the opening 31 of the above-described embodiment. Specifically, the partition 3 has a semicircular shape and a notch 321 at a position corresponding to the liquid extraction tube 26. A groove bottom 3211 is formed at the notch 321. The limiting edge 38 and the groove bottom 3211 of the partition 3 face each other. It should be noted that in the third embodiment, the partition 3 has a first plate (plate) 36a and a second plate (another plate) 36b facing each other. Similar to the second embodiment, the first plate 36a also has a pull rod 34 integrally protruding therefrom.

[0042] The cover 2b has an enclosing inner wall 222, which is provided with a first support portion P1, a second support portion P2, and a third support portion P3, which have three coplanar surfaces. A protruding stopper 28 is further provided on the inner wall 222, and the protruding stopper 28 and the limiting edge 38 correspond to each other. The third support portion P3 and the protruding stopper 28 are both positioned to correspond to the air extraction portion 251.

[0043] When the user holds the pull rod 34 and inserts the partition 3 into the cover 2b, the first support P1, second support P2, and third support P3 can support the partition 3 smoothly through the second plate 36b, and the limiting edge 38 and the protruding stopper 28 can be adjacent to each other, which prevents the partition 3 from rotating relative to the cover 2b and achieves a positional limiting effect. At this time, the liquid extraction tube 26 is accommodated in the notch 321.

[0044] The shape of the partition 3 corresponds to the interior of half of the cover 2b, and the size of the partition 3 is slightly larger than the corresponding portion of the inner wall 222. This makes it more likely to interfere with the inner wall 222 when inserting or removing the partition 3. Therefore, once the partition 3 is inserted into the cover 2b, it will not fall off unless an external force is applied. Preferably, the first support portion P1 and the second support portion P2 are each integrally extended to further form a sloped portion I, and these two sloped portions I are linearly opposed to each other. When the partition 3 is inserted, the outer circumferential edge 37 is guided by the two sloped portions I and abuts against two corresponding portions of the outer circumferential edge 37 so that the two sloped portions I face each other. The two sloped portions I are arranged symmetrically to each other.

[0045] In this specification, the notch 321 and the limiting edge 38 are located at two linearly opposite positions on the partition 3. This prevents the partition 3 from being inverted relative to the cover 2b. The groove bottom 3211 of the partition 3 contacts the liquid extracting tube 26, and the limiting edge 38 contacts the protruding stopper 28. The two sloped sections I are also linearly opposite each other, and the opposing lines of the notch 321 and the limiting edge 38 cross each other with the opposing lines of the two sloped sections I. Thus, the partition 3 is more easily assembled within the cover 2b, with its four sections contacting the liquid extracting tube 26, the protruding stopper 28, and the two sloped sections I on all four sides. The partition 3 of the third embodiment does not require the locking structure S, which further facilitates removal for cleaning.

[0046] 13, the first support portion P1 and the second support portion P2 are located at two positions on the inner wall 222 that are linearly opposed to each other and face each other, and the third support portion P3 is located between the first support portion P1 and the second support portion P2, and the first support portion P1, the second support portion P2, and the third support portion P3 together form a triangular arrangement, ensuring that the three points of the first support portion P1, the second support portion P2, and the third support portion P3 are on the same plane as described above. Also, as shown in FIG. 14, the thickness of each gradient portion I protruding from the inner wall 222 gradually decreases from the liquid inlet 261 to the liquid outlet 262 (from top to bottom), and the thickest points of the two gradient portions I are adjacent to the first support portion P1 and the second support portion P2, respectively.

[0047] In summary, the nasal suction device and the equipment including the nasal suction device according to the present invention can reliably achieve the intended purpose and effect and overcome the drawbacks of the prior art.

[0048] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means devised in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
