Description

[Technical field]

[0001] The present invention relates to a nasal mucus collector and a nasal mucus suction device that sucks and stores suctioned nasal mucus. [Background technology]

[0002] There is a nasal mucus aspirator for relieving stuffy noses in infants, sick people, etc. (see Patent Document 1). The nasal mucus aspirator includes a suction head, a nasal mucus reservoir, and a pump. The suction head is connected to the nasal mucus reservoir. The suction head is a part that is inserted into the nostrils to aspirate nasal mucus. The nasal mucus reservoir is a container that retains nasal mucus sucked by the suction head. The pump is connected to the nasal mucus reservoir via a tube. The pump creates negative pressure in the suction head through the nasal mucus reservoir. This causes nasal mucus to flow from the suction head into the nasal mucus reservoir, where it is then retained. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6959843 Summary of the Invention [Problem to be solved by the invention]

[0004] The nasal mucus reservoir is provided with an outflow suppression structure that suppresses the flow of stored nasal mucus into the pump. When nasal mucus is suctioned, the nasal mucus reservoir assumes various positions as the nasal mucus is suctioned. For example, the nasal mucus reservoir may tilt up, down, left, right, or even be inverted. In such cases, the direction in which the nasal mucus flows in the nasal mucus reservoir varies according to the inclination or position of the nasal mucus reservoir. As a result, there is a risk that some of the nasal mucus may pass through the outflow suppression structure and flow into the pump. [Means for solving the problem]

[0005] A nasal mucus collector that solves the above problems includes a case having an inflow section into which nasal mucus flows and a suction section for drawing the air. The case includes a storage section that stores the nasal mucus that flows in from the inflow section, a first passage that guides the air from a position in the storage section away from the inflow section in a first direction that is the direction of the inflow section, and a second passage that is connected to the first passage and extends in a second direction different from the first direction, and that guides the air from the first passage in the direction of the suction section.

[0006] In addition, a nasal mucus suction device that solves the above-mentioned problems includes the above-mentioned nasal mucus reservoir, a suction head that is connected to the inflow section and inserted into the nostril to suction nasal mucus and air, and a pump that is connected to the suction section and creates negative pressure inside the suction head.

[0007] According to the above configuration, the case is provided with a first passageway that guides air in a first direction and a second passageway that extends in a second direction different from the first direction. This allows the passageway to be long within the limited internal space of the case. Therefore, air and nasal mucus can be firmly separated from the inlet to the suction part, which makes it difficult for nasal mucus to enter the pump.

[0008] In the above nasal mucus reservoir, the first passage may include a first inlet and a first outlet, the first inlet facing the reservoir at a position closer to the suction section than the inflow section, the first passage extending from the first inlet in a direction approaching the inflow section, and the first outlet connected to the second passage. According to the above configuration, the first inlet of the first passage is provided at a position closer to the suction section than the inflow section, and the first passage is extended from there in a first direction approaching the inflow section, thereby making it possible to lengthen the first passage.

[0009] In the above nasal mucus collection device, the second passage may include a second inlet and a second outlet, the second inlet being provided at a position closer to the inflow portion than the suction portion, the second passage extending from the second inlet in a direction approaching the suction portion, and the second outlet being configured at a position closer to the suction portion than the inflow portion. According to the above configuration, the second inlet, which is also the first outlet of the first passage, is provided at a position closer to the inflow portion than the suction portion, and the second passage can be lengthened by extending the second passage from there in a second direction approaching the suction portion.

[0010] In the above nasal mucus storage device, the storage section is a primary storage section that stores the nasal mucus from the inflow section, and the case may be configured to further include a secondary storage section between the second passage and the suction section. According to the above configuration, by providing a secondary storage section just before the suction section in addition to the primary storage section, air and nasal mucus can be separated more reliably.

[0011] In the above nasal mucus storage device, the suction section may be configured to include a tubular portion that protrudes from the peripheral wall of the case into the secondary storage section. According to the above configuration, the tubular portion that is the inflow end from the secondary storage section to the tubular portion protrudes into the secondary storage section. Therefore, the nasal mucus stored in the secondary storage section is less likely to flow into the tubular portion. This allows the air and the nasal mucus to be separated more firmly.

[0012] The nasal mucus collector may be configured to include a partition member that divides the internal space of the case into a first space and a second space, the first space including the inflow section, the storage section, and the first passage, and the second space including the second passage and the suction section. According to the above configuration, the use of a partition member in forming the storage section, the first passage, and the second passage simplifies the shapes of the components. This allows each component to be shaped to be easily cleaned.

[0013] The nasal mucus reservoir may further include a barrier that faces the inflow section at a distance, and the first inlet may be configured on the suction section side separated from the inflow section by the barrier. With the above configuration, the force of the nasal mucus and air flowing from the inflow section to the reservoir can be weakened by colliding with the barrier.

[0014] In the nasal mucus collection device, the first passage and the second passage may be configured along the peripheral wall of the case. According to the above configuration, the first passage and the second passage are configured along the peripheral wall of the case within the limited internal space of the case, so that the passages can be made as long as possible. Effect of the Invention

[0015] The present invention can suppress the outflow of nasal mucus from the suction part. [Brief description of the drawings]

[0017] A nasal mucus suction device 1 to which the present invention is applied will be described below with reference to Figs. 1 to 13. In the following figures, the X direction is the longitudinal direction of the nasal mucus reservoir 3, the Y direction is the width direction of the nasal mucus reservoir 3, and the Z direction is the depth (thickness) direction of the nasal mucus reservoir 3. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0018] 〔overview〕 FIG. 1 is a perspective view showing a state in which a nasal mucus suction device 1 to which the present invention is applied is in use. The nasal mucus suction device 1 is used to remove nasal mucus. The purpose of removing nasal mucus is to make breathing easier and to prevent diseases such as otitis media and sinusitis caused by bacteria in nasal mucus. Infants, in particular, are prone to nasal congestion because they cannot blow their noses themselves, and the nasal mucus suction device 1 is effectively used to remove clogged nasal mucus. This embodiment is a nasal mucus suction device 1 suitable for use with infants. However, the nasal mucus suction device 1 is not limited to use with infants, and can also be used with adults.

[0019] The nasal mucus suction device 1 includes a suction head 2, a nasal mucus reservoir 3, and a pump 4. The nasal mucus reservoir 3 and the pump 4 are connected by a tube 5, which is a flexible tubular body. As shown in FIG. 2, the suction head 2 is a member that is inserted into the nostrils of the nose to suck up nasal mucus. The suction head 2 is a molded body made of a resin material that is flexible as a whole so that it can engage with the nostrils and adhere closely to the inner surface of the nostrils. The suction head 2 is a molded body made of, for example, silicone rubber. The suction head 2 has an insertion part 2a that is inserted into the nostrils and a nose pad part 2b that abuts around the nostrils. The tip of the insertion part 2a has a suction opening 2c for sucking nasal mucus and air. This suction opening 2c communicates with the nasal mucus reservoir 3. The nose pad part 2b is configured to be spread out like an umbrella so that the suction head 2 is not inserted too far into the nostrils. Such a suction head 2 is attached to the inlet part 14 of the nasal mucus reservoir 3.

[0020] The pump 4 is an electric pump that generates negative pressure in the nasal mucus reservoir 3 and the suction head 2 through the tube 5. The pump 4 generates negative pressure by sucking in the air in the nasal mucus reservoir 3 through the tube 5. This negative pressure acts as a suction force to suck in the nasal mucus. In addition, the pump is equipped with a power supply unit, an operation unit, a control unit, etc. The pump 4 supplies power to the drive unit, etc. through a power source such as a commercial power source or a battery. The operation unit is composed of push buttons, dials, etc. for starting and stopping the pump and adjusting the strength of suction, etc. The control unit drives the pump according to input from the operation unit.

[0021] [First embodiment] [Nasal mucus collector 3] As shown in Fig. 2, the nasal mucus collection device 3 includes a case 11 whose overall shape is a rectangular parallelepiped or ellipsoid. In the case 11, the longitudinal direction is the X direction, the width direction is the Y direction, and the depth (thickness) direction is the Z direction. The case 11 includes a lid 12 and a case body 13. The lid 12 and the case body 13 are each molded from a translucent resin material such as acrylic, polycarbonate, ABS, etc. In the first embodiment, the lid 12 and the case body 13 are each molded from a transparent polycarbonate resin.

[0022] The case 11 includes an inflow section 14 and a suction section 15. The suction head 2 is attached to the inflow section 14. The inflow section 14 is provided on the lid 12. The suction section 15 is provided on the case body 13. The suction section 15 is connected to the tube 5. A partition member 16 is disposed inside the case 11. The internal space of the case 11 is divided into a first space 17 and a second space 18 by the partition member 16 (see FIG. 5). The first space 17 is an upper space divided between the lid 12 and the partition member 16. The second space 18 is a lower space divided between the case body 13 and the partition member 16. The first space 17 includes the inflow section 14. The second space 18 includes the suction section 15.

[0023] The inlet section 14 and the suction section 15 are provided, for example, at opposing ends in the X direction. In addition, in the Y direction, the inlet section 14 and the suction section 15 are provided, for example, at the center. Furthermore, in the Z direction, the inlet section 14 is provided on the lid 12 side (upper side), and the suction section 15 is provided on the case body 13 side (lower side). The case 11 is provided, between the inlet section 14 and the suction section 15, with a storage section that stores nasal mucus, and an outflow suppression structure that suppresses the nasal mucus from the storage section from flowing into the suction section 15. The storage section is, for example, a primary storage section 34 described later, and the outflow suppression structure is, for example, a first passage 36, a second passage 37, and a secondary storage section 35, which will be described in detail later.

[0024] [Lid 12] As shown in FIG. 3, the lid 12 includes a lid bottom wall 21 and a lid outer peripheral wall 22. The lid bottom wall 21 is rectangular or elliptical and flat. The lid outer peripheral wall 22 is a wall constituting an upper portion of the outer peripheral wall of the case 11, and is an annular wall provided around the lid bottom wall 21. The lid outer peripheral wall 22 includes a pair of opposing linear lid outer straight walls 22a extending in the X direction, and a pair of opposing first lid outer arc walls 22b and second lid outer arc walls 22c connecting both ends of the pair of lid outer straight walls 22a. The lid outer peripheral wall 22 is formed of a gentle curved surface. An engagement portion 20 is provided around the inner surface of the lid bottom wall 21. The engagement portion 20 is, for example, an annular step portion. Furthermore, a finger hook portion 19 is provided in the middle of the pair of lid outer straight walls 22a in the X direction. Finger hook portion 19 protrudes outward and is a portion on which fingers can be hooked when removing lid 12 from case body 13.

[0025] The first lid outer arc wall 22b has an inflow section 14. The inflow section 14 is provided at the center (top) of the first lid outer arc wall 22b in the Y direction. The inflow section 14 has an inflow side connection tube section 14a protruding outward from the first lid outer arc wall 22b, and an inflow side tube section 14b protruding inward from the first lid outer arc wall 22b. The inflow side tube section 14b is integrally provided to the lid bottom wall 21 by a lid side support base 14c integral with the inflow side tube section 14b. The wall surface of the lid side support base 14c is a surface without unevenness. The lid side support base 14c simplifies the structure by preventing a gap from being formed between the inflow side tube section 14b and the lid bottom wall 21. This makes it easy to clean the lid 12 down to the smallest detail. The inflow side tube section 14b is located away from the lid bottom wall 21.

[0026] A barrier 23 extending in the Y direction is erected in the middle of the lid bottom wall 21 in the X direction. The barrier 23 is a vertical wall perpendicular to the lid bottom wall 21 and faces the inflow side tube portion 14b with a gap therebetween. The barrier 23 is the wall against which the nasal mucus and air flowing in from the inflow side tube portion 14b first collide. The nasal mucus that collide with the barrier 23 then drips. The air flows in the direction of a first passage 36 described below. The tip of the barrier 23 does not contact the outer bottom wall 26 of the case body 13 but is separated therefrom to ensure an air flow path. In addition, the tip of the lid outer peripheral wall 22 is provided with a fitting outer wall 24 that fits with the outer peripheral wall 27 of the case body 13.

[0027] [Case body 13] The case body 13 includes an outer bottom wall 26 and an outer peripheral wall 27. The outer bottom wall 26 is rectangular or elliptical and flat. The outer peripheral wall 27 is a wall constituting the lower part of the peripheral wall of the case 11, and is an annular wall erected around the outer bottom wall 26. The outer peripheral wall 27 includes a pair of opposing outer straight walls 27a extending in the X direction, and a pair of opposing first outer arc walls 27b and second outer arc walls 27c connecting both ends of the pair of outer straight walls 27a. The pair of outer straight walls 27a correspond to the pair of lid outer straight walls 22a, the first outer arc walls 27b correspond to the first lid outer arc walls 22b, and the second outer arc walls 27c correspond to the second lid outer arc walls 22c. The outer peripheral wall 27 is formed of a gently curved surface. Furthermore, the first outer arc wall 27b is provided with a positioning protrusion 30a at the top thereof so as to protrude inward. The positioning protrusion 30a engages with a positioning recess 30b of the partition member 16 for positioning. The second outer arc wall 27c is provided with a suction portion 15.

[0028] The suction section 15 is located on the opposite side to the inlet section 14 in the X direction. The suction section 15 is provided at the center (top) of the second outer arc wall 27c in the Y direction. The suction section 15 includes a suction side connection tube portion 15a protruding outward from the second outer arc wall 27c, and a suction side tube portion 15b protruding inward from the second outer arc wall 27c. The suction side tube portion 15b is provided integrally with the outer bottom wall 26 by a support base 15c integral with the suction side tube portion 15b. The wall surface of the support base 15c is a surface without unevenness. The support base 15c simplifies the structure by preventing a gap from being formed between the suction side tube portion 15b and the outer bottom wall 26. This makes it easy to clean the case body 13 even in small details. The suction side tube portion 15b is located away from the outer bottom wall 26.

[0029] The tip of the outer peripheral wall 27 is provided with an engaging inner wall 28 that engages with the lid outer peripheral wall 22 of the lid 12. The inner surface of the outer peripheral wall 27 is provided with an engaging step portion 29 that engages with the peripheral edge of the partition member 16. A packing 25 is disposed on the outer periphery of the engaging inner wall 28 to ensure watertightness. The packing 25 is, for example, an elastic ring-shaped packing.

[0030] [Partition member 16] As shown in Figs. 3 and 4, the partition member 16 includes an inner bottom wall 31, an inner peripheral wall 32, and a flange 33. As shown in Fig. 5, the partition member 16 defines a first space 17 between the partition member 16 and the lid 12, and defines a second space between the partition member 16 and the case body 13. The first space 17 includes a primary storage section 34 as a storage section that first stores the nasal mucus that flows in from the inflow section 14. The second space 18 includes a secondary storage section 35 that stores the nasal mucus that flows out of the primary storage section 34 and immediately before it flows out of the suction section 15. The first space 17 also includes a first passage 36 through which air and the like flows from the primary storage section 34 toward the secondary storage section 35. The second space 18 includes a second passage 37 that is connected to the first passage 36 and through which nasal mucus and the like flows toward the secondary storage section 35 (see Figs. 6 to 8).

[0031] The inner bottom wall 31 includes a first inner bottom portion 31a, a second inner bottom portion 31b, and a connecting wall portion 31c, which are different in height. The first inner bottom portion 31a forms a deep bottom when viewed from the lid 12, and the second inner bottom portion 31b forms a shallow bottom when viewed from the lid 12. When the partition member 16 is placed in the case body 13, the first inner bottom portion 31a abuts against the inner surface of the outer bottom wall 26 of the case body 13. The second inner bottom portion 31b is spaced apart from the inner surface of the outer bottom wall 26. The first inner bottom portion 31a and the second inner bottom portion 31b are connected by the connecting wall portion 31c. The connecting wall portion 31c is a vertical wall perpendicular to the first inner bottom portion 31a and the second inner bottom portion 31b. Alternatively, when viewed from the lid 12 side, the connecting wall 31c is an inclined wall that forms an obtuse angle with the first inner bottom 31a. The connecting wall 31c is positioned closer to the second outer arc wall 27c than to the first outer arc wall 27b in the X direction. The space between the lid 12 and the first inner bottom 31a and second inner bottom 31b is a primary storage section 34. The space between the second inner bottom 31b and the outer bottom wall 26 is a secondary storage section 35.

[0032] The primary storage section 34 is a main storage section where nasal mucus is mainly stored, and is therefore configured as a larger space than the secondary storage section 35 which is a sub-storage section. Furthermore, within the primary storage section 34, the first portion of the first inner bottom section 31a is a space where the inflow side tubular section 14b and the barrier 23 are located, and where nasal mucus is mainly stored. The second portion of the second inner bottom section 31b is a space where some of the stored nasal mucus flows from the first portion of the first inner bottom section 31a along the connecting wall section 31c as the attitude of the case 11 changes. Since the barrier 23 is located in the first portion of the deep bottom, the second portion is configured so that nasal mucus scattered from the inflow side tubular section 14b is less likely to reach it directly.

[0033] The inner peripheral wall 32 is an annular wall. The inner peripheral wall 32 is located inside and spaced apart from the lid outer peripheral wall 22 and the outer peripheral wall 27. In the first space 17, the inner space surrounded by the inner peripheral wall 32 defines a primary storage section 34. The inner peripheral wall 32 includes a pair of opposing inner linear walls 32a extending in the X direction, and a pair of opposing first inner arc walls 32b and second inner arc walls 32c connecting both ends of the pair of inner linear walls 32a. The first inner arc wall 32b includes a recess 38a that allows clearance for the inflow side cylinder portion 14b and the lid side support base 14c. When the opening of the case body 13 is closed by the lid 12, the inflow side cylinder portion 14b enters and engages with the recess 38a.

[0034] Lid-side end 32d of inner peripheral wall 32 on the lid 12 side is configured to be uniform in height. When partition member 16 is placed in case body 13 and lid 12 is placed, lid-side end 32d engages with engaging portion 20 on the inner surface of lid bottom wall 21. This makes primary storage portion 34 a substantially sealed space except for inflow portion 14. A first passage 36 is defined outside primary storage portion 34.

[0035] As shown in FIG. 4, the second inner arc wall 32c has a large cutout 38b at the second inner bottom 31b. When the partition member 16 is disposed in the case body 13, the suction side cylinder portion 15b enters and engages with the cutout 38b. The cutout 38b is a large opening relative to the suction side cylinder portion 15b. The second inner arc wall 32c is flush with the first inner bottom 31a, and contacts the outer bottom wall 26 when the partition member 16 is disposed in the case body 13. This forms a secondary storage portion 35 on the inside of the second inner arc wall 32c.

[0036] The flange 33 is a piece that protrudes outward in an annular shape from the inner peripheral wall 32. The tip of the flange 33 is engaged and supported by an engaging step 29 provided on the outer peripheral wall 27. The position of the flange 33 is the boundary between the first space 17 and the second space 18. The flange 33 is at the same height as the second inner bottom 31b in the Z direction. The flange 33 is provided with a positioning recess 30b that engages with the positioning protrusion 30a at a position corresponding to the first inner arc wall 32b. The partition member 16 is positioned when placed in the case body 13 by the positioning protrusion 30a engaging with the positioning recess 30b.

[0037] The flange 33 constitutes a first passage 36 and a second passage 37. The first passage 36 and the second passage 37 are provided between the outer peripheral wall 27 and the lid outer peripheral wall 22 and the inner peripheral wall 32. The first passage 36 is located on the lid 12 side, which is the first space 17, and the second passage 37 is located on the case body 13 side, which is the second space 18, at the boundary of the flange 33. Each of the first passage 36 and the second passage 37 is an annular passage located on the outer peripheral portion of the case 11. The first passage 36 and the second passage 37 are arranged vertically (see FIG. 9). The first passage 36 and the second passage 37 are flow paths through which the nasal mucus and air sucked into the pump 4 flow. The first passage 36 is the primary storage section 34, and is a flow path that guides the nasal mucus and air that have reached the suction section 15 side to the first direction of the inflow section 14. Second passage 37 is connected to first passage 36, and is a flow path that guides nasal mucus and air from a position closer to inflow portion 14 than suction portion 15 in a second direction to secondary reservoir 35 where suction portion 15 is located.

[0038] Of the fluid containing nasal mucus and air that flows in from inlet portion 14, most of the nasal mucus is stored in primary storage portion 34. Then, a small amount of nasal mucus flows into first passage 36 together with the air, or due to the inclination of nasal mucus storage device 3. Second passage 37 is located downstream of first passage 36. Therefore, an even smaller amount of nasal mucus flows into second passage 37 together with air than in first passage 36. Then, an even smaller amount of nasal mucus reaches secondary storage portion 35, located downstream of second passage 37, together with air, than in second passage 37.

[0039] Specifically, the first passage 36 is a passage surrounded by the flange 33 of the partition member 16, the inner circumferential wall 32 on the lid 12 side of the flange 33, and the peripheral wall of the case 11. The second passage 37 is a passage surrounded by the flange 33 of the partition member 16, the inner circumferential wall 32 on the case body 13 side of the flange 33, and the peripheral wall of the case 11.

[0040] A through hole penetrating the second inner arc wall 32c from the inside to the outside is provided at a corner between the second inner arc wall 32c and the second inner bottom 31b of the primary storage section 34. This through hole is a first inlet 36a of the first passage 36. The first inlet 36a is provided at a position away from the inlet section 14. For example, the first inlet 36a is provided at a position closer to the suction section 15 than the inlet section 14, that is, at a position adjacent to the suction section 15 in this embodiment.

[0041] The flange 33 is provided with a through hole penetrating vertically. This through hole is the first outlet 36b of the first passage 36. This through hole is a U-shaped through hole with the tip of the flange 33 as the open end. This through hole is large enough for a fingertip such as an index finger to engage with, and is configured to be easy to clean due to its gentle curved shape. The first outlet 36b is also the second inlet 37a of the second passage 37. The first outlet 36b and the second inlet 37a are provided at a position closer to the inlet 14 than the suction section 15, in this embodiment, around the boundary between the first inner arc wall 32b and the pair of inner straight walls 32a.

[0042] The end of the second inner arc wall 32c constituting the cutout portion 38b is largely separated from the suction side cylinder portion 15b and the support stand 15c, and this portion serves as a second outlet 37b to the secondary storage portion 35 in the second passage 37. The second outlet 37b is provided at a position closer to the suction portion 15 than the inlet portion 14.

[0043] [Assembling method] The nasal mucus collector 3 can be disassembled into the case 11, the cover 12, the case body 13, and the partition member 16. The nasal mucus collector 3 is cleaned in a disassembled state. Then, the partition member 16 is placed in the case body 13 first. Specifically, the first outer arc wall 27b and the first inner arc wall 32b are aligned, and the second outer arc wall 27c and the second inner arc wall 32c are aligned. Then, the suction side cylinder portion 15b and the support base 15c are inserted into the notch portion 38b, and the positioning protrusion 30a and the positioning recess 30b are engaged.

[0044] When the partition member 16 is not correctly disposed in the case body 13, the inner peripheral wall 32 hits the suction side cylinder portion 15b, the support base 15c, or the positioning protrusion 30a, and the partition member 16 does not fit into the case body 13.

[0045] Next, the lid 12 is placed on the partition member 16 of the case body 13. Specifically, the first outer arc wall 27b is aligned with the first lid outer arc wall 22b, and the second outer arc wall 27c is aligned with the second lid outer arc wall 22c. Then, the inflow side cylinder portion 14b and the lid side support base 14c are engaged with the recess 38a. As a result, the fitting outer wall 24 is fitted into the fitting inner wall 28. Then, the barrier 23 is positioned within the primary storage portion 34. Note that when the lid 12 is not correctly placed in the case body 13, the inflow side cylinder portion 14b and the lid side support base 14c come into contact with the second inner arc wall 32c, and are not closed.

[0046] In the nasal mucus reservoir 3 configured as above, the first space 17 and the second space 18 are partitioned in the internal space of the case 11. The first space 17 is configured with the inflow side cylinder portion 14b, the primary reservoir portion 34, and the first passage 36. The inflow side cylinder portion 14b is located in a first portion of the first inner bottom portion 31a of the primary reservoir portion 34. The first passage 36 is configured on the lid 12 side around the primary reservoir portion 34 via the inner peripheral wall 32. Furthermore, the barrier 23 is located in the primary reservoir portion 34 in a state where it is spaced apart from and faces the inflow side cylinder portion 14b. The second space 18 is configured with the second passage 37, the secondary reservoir portion 35, and the suction side cylinder portion 15b. The second passage 37 is configured below the first passage 36 around the primary reservoir portion 34. The secondary reservoir portion 35 is located inside the second passage 37. The suction side cylinder portion 15b is positioned in the secondary reservoir portion .

[0047] [Operation of the first embodiment] In the nasal mucus reservoir 3, the end of the tube 5 connected to the pump 4 is connected to the suction side connection tube portion 15a. Also, the suction head 2 connected to the inflow side connection tube portion 14a is engaged with the nostril. When the pump 4 is started, negative pressure is generated in the suction head 2 through the case 11, and suction of nasal mucus and air begins. Then, an air flow is formed in the direction from the suction head 2 to the pump 4.

[0048] As shown in Fig. 5, nasal mucus flows from the inflow side tube portion 14b into the primary storage portion 34 together with the airflow, as indicated by arrow D1. At this time, some of the nasal mucus drips from the inflow side tube portion 14b onto a first portion on the first inner bottom portion 31a in the primary storage portion 34. Some of the nasal mucus also becomes droplets, hits the barrier 23, and drips onto the first inner bottom portion 31a. Then, first, the nasal mucus is stored in the first portion of the deep first inner bottom portion 31a in the primary storage portion 34. In Fig. 5, the stored nasal mucus stored in the first portion of the first inner bottom portion 31a is indicated as "6".

[0049] The air flows in the direction of the shallow second inner bottom portion 31b, bypassing the barrier 23, as shown by the arrow D2. This air may also contain a small amount of nasal mucus. Next, as shown in FIG. 6, the air flows from the first inlet 36a to the first passage 36, as shown by the arrow D2. Then, as shown in FIG. 7, the air flows from the first outlet 36b and the second inlet 37a to the second passage 37, as shown by the arrow D2. Then, as shown in FIG. 8, the air flows to the secondary reservoir 35, as shown by the arrow D2. After that, the air flows in the direction of the pump 4 through the suction side tube portion 15b and the tube 5.

[0050] In this embodiment, the first direction is the direction from the periphery of the suction section 15 toward the inlet section 14. Specifically, the first direction is the direction in which air flows from the first inlet 36a to the first outlet 36b and the second inlet 37a. The second direction is the direction from the periphery of the inlet section 14 toward the suction section 15. Specifically, the second direction is the direction in which air flows from the first outlet 36b and the second inlet 37a to the second outlet 37b.

[0051] Here, the nasal mucus reservoir 3 may tilt up and down, left and right, or become inverted during use. As the posture changes irregularly in this way, a part of the nasal mucus stored in the primary reservoir 34 rides on the air flow in the direction of the arrow D2 and flows from the first part of the first inner bottom 31a to the second part of the second inner bottom 31b. Then, little by little, the nasal mucus rides on the air flow in the direction of the arrow D2 and flows through the first passage 36 and the second passage 37 to the secondary reservoir 35. The first passage 36 and the second passage 37 exist between the primary reservoir 34 and the secondary reservoir 35, and the passages are long. For this reason, the nasal mucus does not easily reach the secondary reservoir 35. Even if the nasal mucus is stored in the secondary reservoir 35, the suction side tube part 15b protrudes into the secondary reservoir 35 and is separated from the outer bottom wall 26 by the support stand 15c. Therefore, the nasal mucus in secondary reservoir 35 is less likely to be discharged from suction side cylinder portion 15b.

[0052] [Effects of the first embodiment] According to the nasal mucus suction device 1 described above, the following effects can be obtained. (1-1) Inside the case 11, there are provided a first passage 36 that guides air etc. in a first direction and a second passage 37 that guides air etc. in a second direction. This makes it possible to lengthen the passages formed within the limited internal space of the case 11. Therefore, air and nasal mucus can be firmly separated from the inlet portion 14 to the suction portion 15, and as a result, it is possible to make it difficult for nasal mucus to enter the pump 4.

[0053] (1-2) The first passage 36 can be made longer by providing the first inlet 36a of the first passage 36 at a position closer to the suction section 15 than the inlet section 14 and extending the first passage 36 from there in the first direction toward the inlet section 14.

[0054] (1-3) The second passage 37 can be made longer by providing the second inlet 37a, which is also the first outlet 36b of the first passage 36, at a position closer to the inlet section 14 than the suction section 15, and extending the second passage 37 from there in a second direction closer to the suction section 15.

[0055] (1-4) By providing secondary reservoir 35 immediately before suction unit 15 in addition to primary reservoir 34, air and nasal mucus can be separated more reliably. (1-5) Suction side tube portion 15b, which is the inflow end from secondary storage portion 35 to suction side tube portion 15b, protrudes into secondary storage portion 35. Therefore, nasal mucus stored in secondary storage portion 35 is less likely to flow into suction side tube portion 15b. This allows air and nasal mucus to be separated more reliably.

[0056] (1-6) The shapes of the components can be simplified by using the partition member 16 in configuring the primary storage section 34, the secondary storage section 35, the first passage 36, and the second passage 37. This allows each component to have a shape that is easy to clean.

[0057] (1-7) The force of the nasal mucus and air flowing from the inflow portion 14 to the primary storage portion 34 can be weakened by colliding with the barrier 23. The nasal mucus from the inflow portion 14 can be prevented from flowing directly into the first passage 36.

[0058] Second Embodiment In the snot reservoir 3 of the first embodiment, the primary reservoir 34 and the secondary reservoir 35 are arranged in the X direction in the internal space of the case 11, the first passage 36 is partitioned around the primary reservoir 34, and the first passage 36 and the second passage 37 are arranged in the Z direction. As shown in Figs. 10 and 11, the snot reservoir 40 of the second embodiment is bottle-shaped as a whole, and the primary reservoir 47, the first passage 48, and the second passage 49 are arranged in the radial direction. That is, the snot reservoir 40 includes a bottle-shaped case 41. The case 41 includes a lid 42 and a case body 43. The lid 42 has a hemispherical shape. The case body 43 has a bottomed cylindrical shape as a whole. In addition, a partition member 46 is arranged in the internal space of the case 41.

[0059] The lid 42 has an inlet portion 44 at the top. The inlet portion 44 has an inlet side connection tube portion 14a to which the suction head 2 is connected. The partition member 46 has a tube portion 51 arranged at the center of the case body 43 and a partition plate 52. The partition plate 52 is a disk, and the tube portion 51 is provided at its center. The tube portion 51 forms a primary storage portion 47 that first stores nasal mucus on its inside. When the tube portion 51 is inserted into the case body 43, the center of the tube portion 51 extends from the bottom wall 56 of the case body 43 toward the lid 42. The tube end of the tube portion 51 is cut out and abuts against the bottom wall 56 to form a first inlet 48a. The outside of the tube portion 51 forms a first passage. The outer peripheral end of the partition plate 52 abuts against the inner surface of the lid 42 when the lid 42 is placed in the case body 43.

[0060] The case body 43 includes a bottom wall 56, an outer peripheral wall 57, and an inner peripheral wall 58. The outer peripheral wall 57 and the inner peripheral wall 58 are integrally provided with the bottom wall 56. The case body 43 also includes a suction section 45 near the bottom wall 56. The suction section 45 includes a suction side connection tube portion 45a. When the partition member 46 is inserted into the case body 43, a first passage 48 is formed between the tube portion 51 and the inner peripheral wall 58. A second passage 49 is formed between the outer peripheral wall 57 and the inner peripheral wall 58. The first passage 48 is an annular passage located on the outer periphery of the primary storage portion 47. The second passage 49 is an annular passage located on the outer periphery of the first passage 48. In the second passage 49, the suction section 45 is located near the bottom wall 56. The tube end of the tube portion 51 is cut out, and a first inlet 48a of the first passage 48 is formed. The tip of the inner circumferential wall 58 is a first outlet 48b of the first passage 48 between the tube portion 51. The tip of the inner circumferential wall 58 is a second inlet 49a of the second passage 49 between the outer circumferential wall 57. The lower side of the partition plate 52 is a connection space connecting the first outlet 48b and the second inlet 49a. In the second passage 49, the opening of the suction portion 45 is the second outlet 49b. In the second embodiment, the secondary storage portion 35 in the first embodiment is omitted.

[0061] [Effect] In the second embodiment, the end of the tube 5 connected to the pump 4 is also connected to the suction side connecting tube portion 45a. The suction head 2 connected to the inflow side connecting tube portion 44a is engaged with the nostril. When the pump 4 is started, negative pressure is generated in the suction head 2 through the case 41, and suction of nasal mucus and air begins. Then, an air flow is generated that flows from the suction head 2 toward the pump 4. As shown in FIG. 11, nasal mucus flows from the inflow portion 44 into the primary storage portion 47 together with the air flow, as indicated by the arrow D1. In FIG. 11, the stored nasal mucus stored in the primary storage portion 47 is indicated as "6".

[0062] As shown by arrow D2, air flows from near the bottom wall 56 of the primary reservoir 47 into the first passage 48 through the first inlet 48a. This air may contain some nasal mucus. The air flows through the first passage 48 and enters the second inlet 49a of the second passage 49 from the first outlet 48b. The air then flows through the second passage 49 toward the second outlet 49b. The air then flows from the suction section 45 through the tube 5 toward the pump 4.

[0063] In the second embodiment, the direction approaching the inlet portion 44 from the suction portion 45 side is the first direction. Specifically, the direction in which air flows from the first inlet 48a to the first outlet 48b is the first direction. Also, the direction in which air approaches the suction portion 45 from the inlet portion 44 side is the second direction. Specifically, the direction in which air flows from the second inlet 49a to the second outlet 49b is the second direction.

[0064] Here, the nasal mucus reservoir 40 changes its position irregularly while in use. During this, some of the nasal mucus stored in the primary reservoir 47 rides on the air flow in the direction of the arrow D2 and flows from the primary reservoir 47 to the first passage 48. Then, little by little, the nasal mucus rides on the air flow in the direction of the arrow D2 and flows through the first passage 48 and the second passage 49 to the suction section 65. In this regard, the first passage 48 and the second passage 49 exist between the primary reservoir 47 and the suction section 65, and the passages are long. For this reason, the nasal mucus is difficult to discharge from the suction section 45.

[0065] [Effects of the second embodiment] The above-described nasal mucus suction device provides the following effects. (2-1) Inside the case 41, there are provided a first passage 48 that guides air etc. in a first direction and a second passage 49 that guides air etc. in a second direction. This makes it possible to lengthen the passages formed within the limited internal space of the case 41. Therefore, air and nasal mucus can be firmly separated from the inlet portion 44 to the suction portion 45, and as a result, it is possible to make it difficult for nasal mucus to enter the pump 4.

[0066] (2-2) The first passage 48 can be lengthened by providing the first inlet 48a of the first passage 48 at a position closer to the suction section 45 than the inlet section 44 and extending the first passage 48 from there in a first direction approaching the inlet section 44. Also, the second passage 49 can be lengthened by providing the second inlet 49a at a position closer to the inlet section 44 than the suction section 45 and extending the second passage 49 from there in a second direction approaching the suction section 45.

[0067] Third Embodiment As shown in Fig. 12 and Fig. 13, the nasal mucus reservoir 60 in the third embodiment is configured with a first passage 68, a second passage 69, and a secondary reservoir 73 arranged below a primary reservoir 67. That is, the nasal mucus reservoir 60 has a rectangular parallelepiped case 61. The case 61 has a lid 62 and a case body 63. A partition member 66 is disposed in the internal space of the case 61. The lid 62 has an inflow section 64 on a side wall 62a. The inflow section 64 has an inflow side connection tube section 64a that protrudes outward from the side wall 63b of the case body 63 near the bottom wall 63a, and an inflow side tube section 64b that protrudes inward from the side wall 63b.

[0068] The case body 63 has a suction section 65 near the bottom wall 63a of the side wall 63b. The suction section 65 has a suction side connection tube portion 65a protruding outward from the side wall, and a suction side tube portion 65b protruding inward from the side wall. The case body 63 also has a partition plate 71 provided above the suction side tube portion 65b. The partition plate 71 is provided parallel to and spaced apart from the bottom wall of the case body 63.

[0069] The partition member 66 is a plate member that is fitted into the case body 63. The partition member 66 includes a first horizontal plate portion 66a, a first vertical plate portion 66b, a second horizontal plate portion 66c, a second vertical plate portion 66d, and a third horizontal plate portion 66e. When the partition member 66 is fitted into the case body 63, it forms a primary storage portion 67 on the lid 62 side. In the primary storage portion 67, a deep first portion is formed in the second horizontal plate portion 66c, and a shallow second portion is formed in the third horizontal plate portion 66e. A notch is provided at the end of the third horizontal plate portion 66e to form a first inlet 68a of the first passage 68. The second vertical plate portion 66d is spaced apart from the tip of the partition plate 71 when arranged in the case body 63.

[0070] The lower side of the third horizontal plate portion 66e is formed with a first passage 68, a second passage 69, and a secondary storage portion 73. The first passage 68 is formed between the third horizontal plate portion 66e and the partition plate 71. The end of the third horizontal plate portion 66e is formed with a first inlet 68a of the first passage 68. The first outlet 68b is formed between the second vertical plate portion 66d and the tip of the partition plate 71. The first outlet 68b is a second inlet 69a of the second passage 69. The second passage 69 is formed between the partition plate 71 and the bottom wall 63a of the case body 63. A rib 72 serving as a weir is provided near the suction side cylinder portion 65b on the bottom wall of the case body 63. The second passage 69 is formed with a portion of the rib 72 as a second outlet 69b. The secondary storage portion 73 is formed between the rib 72 and the suction side cylinder portion 65b. The rib 72 is an obstacle that makes it difficult for the liquid to flow from the second passage 69 to the secondary storage section 73 through the second outlet 69b.

[0071] [Effect] In the third embodiment, the end of the tube 5 connected to the pump 4 is also connected to the suction side connecting tube portion 65a. The suction head 2 connected to the inflow side connecting tube portion 64a is engaged with the nostril. When the pump 4 is started, negative pressure is generated in the suction head 2 through the case 61, and suction of nasal mucus and air begins. Then, an air flow is generated that flows from the suction head 2 toward the pump 4. As shown in FIG. 12, nasal mucus flows from the inflow portion 64 into the primary storage portion 67 together with the air flow, as indicated by the arrow D1. In FIG. 13, the stored nasal mucus stored in the primary storage portion 67 is indicated as "6".

[0072] As shown by arrow D2, air flows from the second portion on the third horizontal plate portion 66e of the primary storage portion 67 into the first passage 68 through the first inlet 68a. This air may contain a small amount of nasal mucus. The air flows through the first passage 68, reaches the first outlet 68b, and flows into the second passage 69 through the second inlet 69a at the same position. The air then flows through the second passage 69 toward the second outlet 69b. The air then flows from the suction portion 65 through the secondary storage portion 73, through the tube 5, toward the pump 4.

[0073] In the third embodiment, the first direction is also the direction approaching the inlet 64 from the suction section 65 side. Specifically, the first direction is the direction in which air flows from the first inlet 68a to the first outlet 68b. Moreover, the second direction is the direction in which air approaches the suction section 65 from the inlet 64 side. Specifically, the second direction is the direction in which air flows from the second inlet 69a to the second outlet 69b.

[0074] Here, the nasal mucus reservoir 60 changes its position irregularly during use. During this, some of the nasal mucus stored in the primary reservoir 67 rides on the air flow in the direction of the arrow D2 and flows from the primary reservoir 67 to the first passage 68. Then, little by little, the nasal mucus rides on the air flow in the direction of the arrow D2 and flows through the first passage 68 and the second passage 69 to the secondary reservoir 73. In this regard, the first passage 68 and the second passage 69 exist between the primary reservoir 67 and the secondary reservoir 73, and the passages are long. For this reason, the nasal mucus in the secondary reservoir 73 is difficult to discharge from the suction section 65.

[0075] [Effects of the third embodiment] The above-described nasal mucus suction device provides the following effects. (3-1) Inside the case 61, there are provided a first passage 68 that guides air etc. in a first direction and a second passage 69 that guides air etc. in a second direction. This makes it possible to lengthen the passages formed within the limited internal space of the case 61. Therefore, air and nasal mucus can be firmly separated from the inlet portion 64 to the suction portion 65, and as a result, it is possible to make it difficult for nasal mucus to enter the pump 4.

[0076] (3-2) The first passage 68 can be lengthened by providing a first inlet 68a of the first passage 68 at a position closer to the suction section 65 than the inlet section 64 and extending the first passage 68 from there in a first direction closer to the inlet section 64. Also, the second passage 69 can be lengthened by providing a second inlet 69a at a position closer to the inlet section 64 than the suction section 65 and extending the second passage 69 from there in a second direction closer to the suction section 65.

[0077] (3-3) By providing secondary reservoir 73 immediately before suction unit 65 in addition to primary reservoir 67, air and nasal mucus can be separated more reliably. [Modifications] The nasal mucus suction device of the first to third embodiments can be further modified as follows. Each embodiment may be modified in the following manner, or may be a combination of at least two mutually compatible modified embodiments in addition to the above embodiment.

[0078] In the first embodiment, the first passage 36 does not have to be provided along the inside of the peripheral wall of the case 11. As an example, the first passage 36 may have a curved shape that enters toward the primary storage section 34, or a wavy shape. That is, the first passage 36 may meander along the way as long as it is a passage from the primary storage section 34 to the inflow section 14. In the first passage 36, the position of the first inlet 36a is not particularly limited as long as it is away from the inflow section 14.

[0079] The second passage 37 may also be curved toward the primary storage section 34 or wavy. That is, the second passage 37 may extend in a direction different from the first direction in which the first passage 36 extends. For example, the second passage 37 may extend so as to intersect with the first passage 36. The second passage 37 may also meander midway. The first passage 36 and / or the second passage 37 configured in this manner can be made even longer than when the passage is provided along the inside of the peripheral wall of the case 11.

[0080] In the first embodiment, the barrier 23 provided on the lid 12 may not be a vertical wall with respect to the lid bottom wall 21. For example, the barrier 23 may be an inclined wall inclined toward the inflow side tubular portion 14b, or may be an inclined wall inclined toward the connecting wall portion 31c. The barrier 23 may be an M-shaped or W-shaped wall in a plan view or bottom view. In this case, it is preferable that the valley portion of the M or W shape faces the inflow side tubular portion 14b. This can weaken the force of the runny nose in the D direction of the airflow from the inflow side tubular portion 14b. Furthermore, the barrier 23 may be multiple instead of one. For example, the multiple barriers may be configured to be arranged in a line in the Y direction with a gap between them, or may be displaced in the X direction with a gap between them. Furthermore, the barrier 23 may be provided on a pair of outer straight walls 27a of the case main body 13 and / or a pair of lid outer straight walls 22a of the lid 12 so as to face the inflow portion 14. The barrier 23 may be omitted. For example, the barrier 23 may be omitted, and the connection wall portion 31c may be configured as a standing wall facing the inlet side cylindrical portion 14b.

[0081] In the second embodiment, a barrier may be provided on the inner wall of the tube portion 51, facing the inflow portion 44. In the tube portion 51, the barrier may be provided with a gap through which nasal mucus can flow down. Also, a barrier such as a fence parallel to the bottom wall 56 and including lattice members (balusters) of a predetermined width that constitute the fence, arranged parallel to or intersecting each other, or a barrier such as a fence with cross-shaped lattice members may be provided on the inner wall of the tube portion 51. Furthermore, in the third embodiment, a barrier extending in the direction of the second horizontal plate portion 66c may be provided on the inner surface of the lid 62.

[0082] In the first embodiment, the partition member 16 may be omitted. In this case, the lid 12 and the case body 13 are configured so that the primary storage section 34, the first passage 36, the second passage 37, and the secondary storage section 35 are configured by combining the lid 12 and the case body 13.

[0083] In the second embodiment, the partition member 46 may be omitted. In this case, the lid 42 and the case body 43 are configured so that the primary storage section 47, the first passage 48, and the second passage 49 are formed by combining the lid 42 and the case body 43.

[0084] In the third embodiment, the partition member 66 may be omitted. In this case, the lid 62 and the case body 63 are configured so that the primary storage section 67, the first passage 68, the second passage 69, and the secondary storage section 73 are configured by combining the lid 62 and the case body 63.

[0085] In the first embodiment, the inflow section 14 may be configured to omit the inflow side tubular section 14b and have no protruding section on the primary storage section 34 side. This allows the configuration of the lid 12 to be simplified and the shape to be easy to clean. Also, the suction section 15 may be configured to omit the suction side tubular section 15b and have no protruding section on the secondary storage section 35 side. This allows the configuration of the case body 13 to be simplified and the shape to be easy to clean.

[0086] In the second embodiment, the inflow portion 44 may have an inflow side cylindrical portion protruding toward the primary storage portion 47, which is the inside of the lid 42. The suction portion 45 may also have an outflow protrusion protruding inward.

[0087] In the third embodiment, the inflow portion 64 may be configured so that the inflow side cylinder portion 64b is omitted and no protruding portion protrudes toward the primary storage portion 67 side. This allows the configuration of the lid 62 to be simplified and the shape to be easy to clean. Also, the suction portion 65 may be configured so that the suction side cylinder portion 65b is omitted and no protruding portion protrudes toward the secondary storage portion 73 side. This allows the configuration of the case main body 63 to be simplified and the shape to be easy to clean.

[0088] In the first embodiment, the secondary storage section 35 may be omitted. In this case, the inner circumferential wall 32 of the partition member 16 may be extended to the position of the suction side cylinder section 15b so that the second passage 37 extends to the position of the suction side cylinder section 15b. The second outlet 37b of the second passage 37 becomes an opening of the suction side cylinder section 15b. In the third embodiment, the rib 72 may be omitted, and the boundary between the second outlet 69b of the second passage 69 and the secondary storage section 73 may not be distinguished.

[0089] In the first embodiment, the positions of the through holes of the flange 33 constituting the first outlet 36b and the second inlet 37a may be provided at a position corresponding to the center (top) of the first inner arcuate wall 32b in the Y direction.

[0090] In the first embodiment, the inflow portion 14 may be provided at a position other than the center (top) of the first lid outer arc wall 22b in the Y direction. For example, the inflow portion 14 may be provided at any position of the pair of lid outer straight walls 22a or at any position of the lid bottom wall 21. Furthermore, the inflow portion 14 may be provided at any position of the first outer arc wall 27b of the case body 13 or at any position of the pair of outer straight walls 27a.

[0091] In the first embodiment, the suction portion 15 may be provided at a position other than the center (top) of the second outer arc wall 27c in the Y direction. For example, the suction portion 15 may be provided at any position of the pair of outer straight walls 27a or at any position of the outer bottom wall 26. Furthermore, the suction portion 15 may be provided at any position of the second lid outer arc wall 22c or at any position of the pair of lid outer straight walls 22a.

[0092] The overall shape of the nasal mucus reservoir 3, the lid 12 and the case body 13 may be a shape close to a rectangular parallelepiped as shown in Fig. 12, a shape close to an ellipsoid as shown in Fig. 2, or an intermediate shape that transitions from a rectangular parallelepiped shape to an ellipsoid shape. Furthermore, the nasal mucus reservoir 3 may be a diamond shape.

[0093] The nasal mucus reservoir 3 may further include a third passage, a fourth passage, etc., between the outlet of the second passage and the secondary reservoir or the suction portion. For example, the third passage extends in a third direction different from the second passage, and is configured to connect the second outlet of the second passage and the suction portion or the secondary reservoir. The fourth passage extends in a fourth direction different from the third passage, and is configured to connect the outlet of the third passage and the suction portion or the secondary reservoir. In this way, by providing more passages downstream of the second passage, the passage becomes longer, and the air and nasal mucus can be separated more firmly, and as a result, it is difficult for nasal mucus to enter the pump 4. The number of passages provided downstream of the second passage and between the suction portion or the secondary reservoir is not particularly limited.

[0094] The pump 4 does not have to be an electric type, but may be a type in which an operator such as a parent holds the tip of the tube 5 in their mouth and sucks, or a type that generates negative pressure using a manual dropper or pump.

[0095] The suction head 2 and the nasal mucus reservoir 3 may be connected by a tube. [Explanation of symbols]
