Nose suction device and apparatus having a nose suction device

Abstract

The application relates to a nose suction device and an equipment with the same. The nose suction device comprises a suction port, a storage bottle, a cover and a partition plate. The storage bottle is used for storing nasal discharge. The cover is combined with the storage bottle to jointly define an internal space. A dip tube is arranged in the cover and extends into the internal space. One end of the dip tube is connected with the cover and is provided with a liquid inlet hole in communication with the outside. The other end of the dip tube extends away from the cover and is provided with a liquid outlet hole. A gas flow channel is defined between the suction port and the liquid outlet hole. The partition plate is arranged in the internal space and partially seals the gas flow channel on one side of the dip tube close to the suction port. The gas flow channel on the other side of the dip tube away from the suction port is not sealed by the partition plate, so as to define an open part for gas flow. Therefore, the nasal discharge in the bottle can be effectively prevented from flowing back into the suction tube.

Description

Technical Field

[0001] This application relates to devices for aspirating nasal mucus, and in particular to a nasal aspirator with an anti-backflow function and equipment having a nasal aspirator. Background Technology

[0002] Nasal aspirators are mainly used by people who have difficulty or are unable to blow their noses, such as infants and young children. They must be connected to a suction device to use the external force provided by the suction device to suck out the mucus from the person's nasal cavity and temporarily store it in a bottle.

[0003] While conventional nasal aspirators have the aforementioned functions, they are prone to causing mucus to flow back into the negative pressure inhalation tube because the channel inside the bottle is close to the negative pressure inhalation tube, a problem that has long been criticized.

[0004] Therefore, how to overcome the shortcomings of the aforementioned prior technologies is a major issue that the creator of this application urgently needs to address. Utility Model Content

[0100] The detailed description and technical content of this application are explained below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.

[0101] This application provides a nasal aspirator and a device with a nasal aspirator. The nasal aspirator is for use by people who have difficulty or are unable to blow their noses. It must be connected to a suction device to use the negative pressure provided by the suction device to suction out the mucus in the person's nasal cavity and temporarily store it in a bottle.

[0102] like Figure 1 and Figure 11 As shown, the device with a nasal aspiration device of this application includes: an air suction device and nasal aspiration devices 100a and 100b. The nasal aspiration devices 100a and 100b are connected to and communicate with the air suction device. The air suction device can aspirate nasal mucus by providing negative pressure to the nasal aspiration devices 100a and 100b.

[0103] like Figures 1 to 4 As shown, the first embodiment of the nasal suction device 100a of this application includes: a storage bottle 1, a cover 2a, and a partition 3.

[0104] The storage bottle 1 is used to temporarily store the suctioned nasal mucus and has a bottle mouth 111 at one end. The body of the storage bottle 1 may also have a necked section 11 at the bottle mouth 111.

[0105] The cover 2a is used to align with the neck 11 of the storage bottle 1. The assembled nasal aspirator 100a together encloses the internal space Z between the cover 2a and the storage bottle 1. The cover 2a has an air extraction port 251 and a hollow liquid suction tube 26 inside the cover 2a. The cover 2a has a liquid inlet 261, and one end of the liquid suction tube 26 is connected to the cover 2a corresponding to the liquid inlet 261. The liquid suction tube 26 extends integrally from its connection point into the internal space Z and passes through the air extraction port 251. The extended end (free end) of the liquid suction tube 26 forms a liquid outlet 262 away from the cover 2a. The air extraction port 251 and the liquid outlet 262 are interconnected and together define the gas flow channel 2135. When the suction device provides negative pressure to the nasal aspirator 100a, the negative pressure draws out the user's nasal mucus through the suction port 251, the liquid outlet 262 and the liquid inlet 261 of the liquid suction tube 26, and the nasal mucus is then guided into the storage bottle 1 for storage through the liquid suction tube 26.

[0106] It should be noted that, in this embodiment, the cover 2a includes a cover body 21 and a suction head 22 connected to each other, as described below.

[0107] The cover body 21 includes a surrounding plate 211 and a cover plate 213. The surrounding plate 211 has two openings opposite to each other. The cover plate 213 connects to and partially closes one of the openings of the surrounding plate 211 to define the opening. The cover plate 213 has an inner side 2131 and an outer side 2132 opposite to each other.

[0108] The suction head 22, corresponding to the gas flow channel 2135, is connected to the cover plate 213 from the outer side 2132 corresponding to the opening. The suction head 22 can be a three-dimensional cone shape as shown in the figure, with a surrounding inner peripheral wall 222. The aforementioned air extraction port 251 is opened on one side of the suction head 22. Figure 2 , Figure 4 and Figure 5 As shown, the cover body 21 has a central portion C, the opening is spaced apart from the central portion C, and the suction head 22 is connected to the cover plate 213 in a manner offset from the aforementioned central portion C, so that the suction head 22 is eccentrically positioned relative to the cover body 21.

[0109] Furthermore, the suction head 22 may also include a suction tube 25, which is connected to the suction head 22 corresponding to the suction port 251. It should be noted that, because the suction head 22 is eccentrically connected to the cover plate 213, the outer surface 2132 of the cover plate 213 can... Figure 2 The suction pipe 25 shown is stacked on the outer side 2132, so that the suction pipe 25 is supported by the cover body 21, which has the effect of not being easily broken by external forces such as impact.

[0110] It should be noted that the partition 3 can be disposed inside or outside the cover 2a, or it can be disposed inside the storage bottle 1, as long as it is located within the internal space Z. This application does not limit this. In this embodiment, the partition 3 will be described with the example of being disposed inside the cover 2a.

[0111] In this embodiment, because the suction head 22 is eccentrically connected to the cover plate 213, the inner surface 2131 of the cover plate 213 can be... Figures 3 to 5 The diagram shows a connection point (not indicated) other than the gas flow channel 2135. In this way, the partition 3 can be attached to the connection point on the inner side 2131 of the cover plate 213. The connection method can be to stick them together (for example, to attach one side of the partition 3 to the connection point on the inner side 2131) or to snap them together. Of course, through the design of the manufacturing process, the partition 3 can also be attached to the cover plate 213 by using the size design between the enclosure plate 211 and the partition 3.

[0112] like Figure 6 and Figure 7 As shown, to allow the partition 3 and the cover plate 213 to be detachably and securely fastened together, a fastening structure S can be added between them. The fastening structure S includes a locking member S1 that can be locked together and a recessed portion S2. The recessed portion S2 can be a groove or a through opening. Figure 6 As shown, the recessed portion S2 is recessed from the inner side 2131 of the cover plate 213 towards the outer side 2132, and the engaging member S1 protrudes from one side of the partition plate 3 corresponding to the recessed portion S2; as Figure 7 As shown, then with Figure 6 Conversely, the recessed portion S2 is recessed from one side of the partition plate 3 toward the other side (or recessed to the point of penetration), while the engaging member S1 protrudes from the inner side 2131 of the cover plate 213 corresponding to the recessed portion S2.

[0113] See also Figure 8 The suction tube 25 of the nasal aspirator 100a of this application is connected to the aforementioned suction device (for example, a manual suction machine 800 as shown in the figure) via the connecting tube 5. When you want to aspirate nasal mucus, align the suction head 22 with its liquid inlet 261 with the nostril, and then operate the suction device to start drawing air through the suction tube 25 to provide negative pressure. This allows the nasal aspirator 100a to aspirate nasal mucus through the suction tube 25, the opening of the gas flow channel 2135, and the liquid suction tube 26, and the nasal mucus to flow out through the liquid outlet 262 and be temporarily stored in the storage bottle 1.

[0114] Therefore, after the partition 3 is installed inside the cover 2a, it will partially seal off the gas flow channel 2135, especially as... Figure 8As illustrated in the cross-sectional view, the gas flow channel 2135 on the side of the liquid suction tube 26 corresponding to the air extraction port 251 is closed, while the other side of the liquid suction tube 26 relative to the air extraction port 251 is formed as an open part. In this way, the air extraction path of the gas flow channel 2135 is blocked. When the storage bottle 1 contains nasal mucus, the nasal mucus will be attracted by negative pressure and will be prevented from flowing back into the air extraction port 251 and causing contamination due to the long air extraction path.

[0115] Special note: The air extraction device can be used for, for example... Figure 1 and Figure 8 The manual vacuum pump 800 shown can also be used as follows: Figure 9 As shown in the example of the electric vacuum pump M, this application does not limit it.

[0116] See also Figure 1 and Figure 8 The manual vacuum pump 800 includes a pump 8 and an operating handle 9. The pump 8 comprises a cylinder 81 and a cap 83 assembled together. The cylinder 81 has a vacuum pipe 812, and the cap 83 has an integrally extended handle 832. The operating handle 9 is telescopically inserted into the pump 8 and connected to a piston 91. A return spring 92 elastically supports the piston 91 between the cap 83 and the piston 91. In operation, the user pulls the operating handle 9 to move the piston 91 within the pump 8. Simultaneously, the piston 91 is elastically compressed, creating negative pressure by drawing air through the vacuum pipe 812. Releasing the force applied to the operating handle 9 allows the piston 91 to return to its original position using the return spring 92.

[0117] It should be noted that, as Figure 3 and Figure 4 As shown, the partition 3 is correspondingly disposed inside the cover body 21 and flatly covers the inner side 2131 of the cover plate 213, partially sealing the gas flow channel 2135, thus defining the unsealed portion of the gas flow channel 2135 as an open portion 31. The open portion 31 is located on the other side of the liquid suction pipe 26 and away from the air extraction port 251. It should be noted that the open portion 31 can be formed by an opening 311 formed on the partition 3, or it can be formed by an unsealed portion of the partition 3 with a semi-circular outline. This application does not impose any limitations on the shape or form of the open portion 31, as long as it allows the air extraction port 251 to communicate with the liquid suction pipe 26.

[0118] In addition, to further enhance the anti-reflux effect of nasal mucus in the bottle, such as Figures 3 to 5As shown, the length of the suction tube 26 extending into the storage bottle 1 can be increased, thereby increasing the distance between the outlet hole 262 of the suction tube 26 and the air extraction port 251 and extending the air extraction path, thus enhancing the effect of preventing nasal backflow. The cover body 21 of the cap 2a has a cap opening 214, with an opening 31 located adjacent to the cap opening 214. The suction tube 26 protrudes a certain distance from the cap opening 214 and extends into the storage bottle 1. The cap 2a can be assembled with its cap opening 214 corresponding to the aforementioned bottle opening 111 at the necked portion 11 of the storage bottle 1.

[0119] like Figures 3 to 5 As shown, to avoid the liquid suction pipe 26, the partition 3 may be provided with a clearance portion 32, which allows the liquid suction pipe 26 to be avoided. Specifically, the clearance portion 32 may be a C-shaped notch as shown in the figure, which communicates with the open portion 31, or it may be a perforation that is not shown in the figure but is arranged in a surrounding shape. In this way, the liquid suction pipe 26, which is located at the center of the suction head 22 and the gas flow channel 2135, can be accommodated in the notch or perforation and thus avoided.

[0120] It should be noted that, because the suction head 22 is eccentrically connected to the cover plate 213, therefore, as Figure 5 As shown, the suction tube 26 connected to the suction head 22 is also offset from the center C of the cap body 21. Correspondingly, the partition 3 must also be eccentrically set so that the opening portion 31 and the clearance portion 32 of the partition 3 are also offset from the center C of the cap body 21. In this way, it is not easy for the user to install the partition 3 in the wrong direction, because if the direction is wrong, the suction tube 26 and the clearance portion 32 will be misaligned, making it impossible to install the partition 3. In other words, the eccentrically set partition 3 becomes a foolproof measure in this embodiment.

[0121] like Figures 3 to 5 As shown, the partition 3 and the cover body 21 are designed with dimensions such that the partition 3 can only be joined and separated from the cover body 21 in a single direction, either vertically or linearly. Since the partition 3 is located inside the cover body 21, and the clearance portion 32 of the partition 3 is also attached to the outer wall of the liquid-drawing tube 26, when the partition 3 is to be removed for cleaning the cover 2a, if the partition 3 cannot be pulled out linearly along the liquid-drawing tube 26, i.e., if the withdrawal angle is slightly off, the clearance portion 32 of the partition 3 will interfere with the outer wall of the liquid-drawing tube 26, making it difficult to remove the partition 3 from the cover 2a. Therefore, a pull rod 34 can be protruding from the partition 3, with the pull rod 34 and the liquid-drawing tube 26 spaced apart and arranged side-by-side (e.g., parallel to each other). In this way, the user can simply grab the pull rod 34 and pull it straight back to remove the partition 3 from the cover 2a along the liquid-drawing tube 26. Specifically, the partition 3 has a first plate surface 36a, and the pull rod 34 extends integrally from the first plate surface 36a. Preferably, as follows... Figure 5The hand lever 34 shown is located between the clearance part 32 and the outer periphery of the partition 3. Because its position is close to the center of the first plate surface 36a, it has a more labor-saving effect. It is preferable that the clearance part 32, the hand lever 34 and the air extraction port 251 are all arranged on the same straight plane.

[0122] For example Figure 10 As shown, the partition 3 in this embodiment can also be disposed inside the storage bottle 1. For example, a support structure 12 can be provided around the inner wall of the storage bottle 1 so that the partition 3 can be positioned by being supported by the support structure 12 inside the storage bottle 1.

[0123] like Figures 11 to 12 As shown, this is the second embodiment of the nasal suction device 100b of this application. The second embodiment is largely the same as the first embodiment described above, except that the cover 2b is different from the cover 2a of the first embodiment.

[0124] In this embodiment, the cover body 21 and the suction head 22 of the cover 2b are coaxially arranged, that is, the centers of the cover body 21 and the suction head 22 are aligned with each other, and the cover body 21 has only a surrounding plate 211. The surrounding plate 211 has two openings opposite to each other and two upper and lower plate edges. The suction head 22 is connected to one of the openings and one of the plate edges and protrudes integrally in one direction. The suction head 22 has a surrounding inner peripheral wall 222.

[0125] Furthermore, in order to integrate the partition 3, a support 255 is formed within the suction head 22. The suction pipe 25 has an outer section 256 that is exposed outside the cover 2b. The support 255 protrudes within the suction head 22, as shown in the figure, extending a certain length from the inner peripheral wall 222. In this way, the partition 3 can be integrated into the support 255 using the integration method disclosed in this application.

[0126] Furthermore, since the cover body 21 and the suction head 22 are coaxially arranged, and the liquid suction tube 26 and the clearance portion 33 of the partition 3 are coaxially arranged and located at the aforementioned central portion C of the cover body 21, the partition 3 will rotate relative to the cover 2b. In order to prevent the partition 3 from rotating relative to the cover 2b, a limiting body 27 and a limited portion 35 can be provided at the adjacent positions between the partition 3 and the cover body 21, so that the limiting body 27 and the limited portion 35 can be mutually limited by corresponding engagement, thereby preventing the partition 3 from rotating relative to the cover 2b; furthermore, it also has a foolproof effect, because the opening portion 31 of the partition 3 must be kept away from the air extraction port 251.

[0127] Specifically, the limiting body 27 can be a protrusion protruding from the cover body 21, and the limited part 35 can be a cut edge opened on the partition 3 and corresponding to the limiting body 27, so that the cut edge (limited part 35) forms a corresponding recess relative to the shape of the protrusion (limiting body 27) relative to the outer periphery 37 of the partition 3.

[0128] In addition, such as Figure 11 As shown, a screw-in structure T may also be provided between the cover 2b and the storage bottle 1, so that the cover 2b can be detachably screwed to the storage bottle 1. It should be noted that in the first embodiment of the nasal suction device 100a of this application, its cover 2a can also be detachably screwed to the storage bottle 1.

[0129] like Figures 13 to 14 As shown, this is the third embodiment of the nasal aspiration device 100b of this application. The third embodiment is largely the same as the aforementioned second embodiment, except that the structure of part of the cover 2b and part of the partition 3 are different from those in the second embodiment. It should be noted that, within the scope of the various embodiments disclosed in this application, the suction port 251 and the suction tube 25 can also be modified to be located on one side of the storage bottle 1, as long as the distance between the suction port 251 and the liquid outlet 262 can be maintained to form a gas flow channel 2135, all of which fall within the scope of this application.

[0130] The partition 3 is correspondingly disposed inside the cover 2b and partially encloses the gas flow channel 2221 of the cover 2b, so as to form a space between the inner peripheral wall 222 and the outer peripheral edge 37 within the cover 2b. Figure 13 The unclosed portion N shown is the open portion 31 described in the aforementioned embodiment. Specifically, the partition 3 is semi-circular and has a notch 321 at the position corresponding to the liquid suction pipe 26, and a groove bottom surface 3211 is formed at the position of the notch 321. The limiting cut edge 38 of the partition 3 is opposite to the groove bottom surface 3211. It should be noted that in the third embodiment, the partition 3 also has a first plate surface 36a and a second plate surface 36b that are opposite to each other, and the first plate surface 36a is also the same as in the second embodiment, with a handle 34 integrally protruding.

[0131] The inner peripheral wall 222 of the cover 2b, which is in a surrounding shape, is provided with a first support portion P1, a second support portion P2, and a third support portion P3, which are three points coplanar with each other; the inner peripheral wall 222 is also provided with a limiting protrusion 28, which corresponds to the aforementioned limiting cut edge 38. Among them, the third support portion P3 and the limiting protrusion 28 are both configured to correspond to the air extraction port 251.

[0132] The user inserts the partition 3 into the cover 2b by holding the lever 34. The partition 3 is then stably supported by the first support P1, the second support P2, and the third support P3 on its second surface 36b. Furthermore, the limiting edge 38 and the limiting protrusion 28 are in mutual contact, preventing the partition 3 from rotating relative to the cover 2b and achieving a limiting effect. It should be noted that the liquid suction tube 26 is housed within the notch 321 at this time.

[0133] In addition to corresponding to the interior of half of the cover 2b, the shape of the partition 3 can also be slightly larger than the corresponding part of the inner peripheral wall 222, so that it can interfere with the inner peripheral wall 222 when it is inserted or removed. Therefore, after the partition 3 is inserted into the cover 2b, it will not fall off unless an external force is applied. Preferably, the first support P1 and the second support P2 are each integrally extended to form ramp blocks I, and these two ramp blocks I are linearly opposite each other. When the partition 3 is inserted, the outer periphery 37 is guided by the two ramp blocks I, thereby causing the two ramp blocks I to abut against two corresponding parts of the outer periphery 37. The two ramp blocks I are symmetrically arranged.

[0134] It should be noted that the aforementioned notch 321 and the limiting edge 38 are located at two opposite positions of the partition 3, which are directly opposite each other. Therefore, the partition 3 can abut against the liquid-drawing pipe 26 with its bottom surface 3211 and against the limiting protrusion 28 with its limiting edge 38. Thus, the partition 3 will not have the problem of flipping relative to the cover 2b. Furthermore, the two ramp blocks I are also directly opposite each other, and the lines opposite to the notch 321 and the limiting edge 38 intersect the lines opposite to the two ramp blocks I in a cross shape. Therefore, the partition 3 will be more stably assembled in the cover 2b because its four parts are abutted by the liquid-drawing pipe 26, the limiting protrusion 28 and the two ramp blocks I from four sides. In other words, the partition 3 in the third embodiment does not need to be provided with the aforementioned locking structure S. Therefore, this application also has the effect of facilitating disassembly and cleaning.

[0135] It should also be noted that, as Figure 13 As shown, the first support P1 and the second support P2 are located at two positions on the inner peripheral wall 222 that are directly opposite each other and face to face. The third support P3 is located between the first support P1 and the second support P2. The first support P1, the second support P2, and the third support P3 together form a triangular arrangement to ensure that the first support P1, the second support P2, and the third support P3 can be three points coplanar with each other as described above. In addition, as Figure 14 As shown, the thickness of each ramp block I protruding relative to the inner peripheral wall 222 gradually decreases from the liquid inlet hole 261 toward the liquid outlet hole 262 (from top to bottom), and the thickest parts of the two ramp blocks I are adjacent to the first support part P1 and the second support part P2, respectively.

[0136] In conclusion, the nasal aspiration device and the equipment having the nasal aspiration device of this application can indeed achieve the intended use purpose and effect, and can solve the shortcomings of the prior art. Therefore, this patent application is filed.
