DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The nasal mucus suction device and the nasal mucus suction device equipped therewith according to the embodiment of the present invention will be described in detail below with reference to the drawings. The embodiment described below is a preferred specific example for carrying out the present invention, and therefore various technical limitations are imposed. However, the present invention is not limited to this embodiment unless otherwise specified in the following description to limit the invention. In addition, when there is a notation "~" indicating a range in the description, it includes an upper limit and a lower limit. In addition, the up-down direction and the left-right direction in the description correspond to the up-down direction and the left-right direction in FIG. 8 and FIG. 9.

[0017] As shown in Figures 1 to 9, the nasal mucus aspirator comprises a nasal mucus aspirator 1, a pump 2, an operating unit 21, a support unit 3, a connecting tube 4, a connecting tube locking unit 5, a nasal mucus aspirator locking unit 6, a cover 7, a first check valve V1, a second check valve V2, etc.

[0018] The nasal mucus suction device 1 is a member having an air hole 1a through which the air of the nasal mucus suction device 1 flows in and out, contacting the nose of the person to be suctioned and storing the nasal mucus, and further having a suction head 11 having a suction hole 1b for suctioning the nasal mucus of the person to be suctioned, and a suction container 12 having a first check valve V1 for passing the internal air when the inside of the nasal mucus suction device 1 is in a decompressed state and a second check valve V2 for discharging the air to the outside when the inside of the nasal mucus suction device 1 is in a pressurized state, and storing the suctioned nasal mucus. The nasal mucus suction device 1 can suck and store the nasal mucus of the person to be suctioned, and even if the suctioned nasal mucus flows to the first check valve V1 side, it contacts the first check valve V1 and is therefore less likely to flow from the nasal mucus suction device 1 to the connecting tube 4.

[0019] The suction head 11 is provided with a suction tube 111 that communicates with the suction hole 1b and extends to the lower side of the suction container 12. As shown in Figs. 2, 4, 5, 8, 9, etc., the tip side of the suction head 11 where the suction hole 1b is provided is tapered so that it can be easily inserted directly into the nostrils of the person to be suctioned. As shown in Figs. 5, 8, and 9, the suction tube 111 is bent in an approximately "L" shape so that the suctioned nasal mucus hits the inside of the suction tube 111 and suppresses the momentum during suction. Furthermore, since the suction head 11 is a member that directly contacts the nose of the person to be suctioned, it is preferable that the suction head 11 is made of elastic resin such as silicone resin, isoprene rubber, or butadiene rubber so that the person to be suctioned is not hurt during suction and is easy to clean after use. In this embodiment, the suction tube 111 is a straight tube that is bent halfway, but in other embodiments, it may be curved. In this embodiment, the suction head 11 is formed of one member, but in other embodiments, the suction head 11 may be formed of a plurality of detachable members at a location including the suction hole 1b.

[0020] The suction container 12 is provided with a vent pipe 121 that is connected to the vent hole 1a, extends to the upper side of the suction container 12, and has a first check valve V1 and a second check valve V2. As shown in Figs. 2, 5, 8, and 9, the vent pipe 121 has a shape that is approximately U-shaped and branches at the lower side. The first check valve V1 is fitted to the upper end of the vent pipe 121, the second check valve V2 is fitted to the end of the branch on the lower side of the vent pipe 121, and the lower end of the vent pipe 121 forms a vent hole 1a with no valve fitted thereto. The first check valve V1 is inserted and fitted to the upper end of the vent pipe 121 from the dome-shaped tip side having a crack that opens when the inside of the nasal mucus suction device 1 is in a reduced pressure state. The second check valve V2 is inserted and fitted at the end of the branch on the lower side of the ventilation pipe 121 so that its dome-shaped tip side having a slit that opens when the inside of the nasal mucus suction device 1 is pressurized is positioned outside the ventilation pipe 121. By providing the first check valve V1 and the second check valve V2 in this way on the ventilation pipe 121, when suctioning the nasal mucus of the person to be suctioned, the pump 2 is operated to exhaust air from the ventilation hole 1a and the inside of the nasal mucus suction device 1 is reduced in pressure, but the slit on the tip side of the first check valve V1 opens to connect the ventilation hole 1a and the suction hole 1b, and the slit on the tip side of the second check valve V2 does not open, so that the nasal mucus of the person to be suctioned can be suctioned. On the other hand, during the interval before the nasal mucus of the person to be aspirated is aspirated again, the pump 2 is operated to supply air from the ventilation hole 1a to pressurize the inside of the nasal mucus suction device 1, and the crack at the tip side of the first check valve V1 does not open, and the crack at the tip side of the second check valve V2 opens, so that the air can be discharged to the outside of the nasal mucus suction device 1 so that the nasal mucus and the like stored inside the nasal mucus suction device 1 does not flow back to the suction hole 1b. Furthermore, the first check valve V1 and the second check valve V2 are preferably formed of elastic resin such as silicone resin, isoprene rubber, butadiene rubber, so that the air inside the nasal mucus suction device 1 flows smoothly when the pump 2 is operated, and so that they are easy to clean after use. In this embodiment, the ventilation pipe 121 is a straight pipe that is not bent in the middle except for the branched part, but in other embodiments, it may be bent or curved in a straight line.

[0021] As shown in Figures 5, 8 and 9, by configuring the suction head 11 and the suction container 12 in this way, the lower end of the suction tube 111 and the upper end of the ventilation tube 121 are relatively far apart in the nasal mucus aspirator 1, so that aspirated nasal mucus, etc., are less likely to flow from the nasal mucus aspirator 1 to the connecting tube 4. In addition, it is preferable that the suction head 11 and the suction container 12 are detachable. Specifically, it is preferable that the suction head 11 and the suction container 12 are detachably fitted together, and with this configuration, the nasal mucus aspirator 1 can be easily washed after use.

[0022] The pump 2 is a member having a piston 22 with an operating part 21, and a pump container 23 with the piston 22 disposed therein and having an intake and exhaust hole 23a. The inside of the nasal mucus suction device 1 can be manually depressurized or pressurized by the pump 2 through the communicating tube 4, thereby aspirating the nasal mucus of the person to be aspirated.

[0023] The operation unit 21 is a member with which the user places his / her finger to move the piston 22 up and down, and in this embodiment, it is formed in an elliptical ring shape via a rod-shaped member on the upper part of the piston 22. The user inserts his / her finger into the ring-shaped operation unit 21 to move the piston 22 up and down. Note that, although the operation unit 21 is ring-shaped in this embodiment, in other embodiments, it may be rod-shaped or curved in a substantially arc shape as long as the user can place his / her finger on it.

[0024] The piston 22 can move up and down inside the pump container 23 by the operating unit 21, thereby making the inside of the nasal mucus suction device 1 in a decompressed state or a pressurized state through the communication tube 4. Specifically, the inside of the nasal mucus suction device 1 can be made in a decompressed state by the piston 22 moving to the upper part of the pump container 23, and the inside of the nasal mucus suction device 1 can be made in a pressurized state by the piston 22 moving to the lower part of the pump container 23. In addition, as shown in Figs. 8 and 9, a piston ring 221 made of an elastic member is preferably provided on the outer periphery of the piston 22 in order to improve the sealing by sliding against the inner wall of the pump container 23. In this embodiment, the piston 22 is substantially disc-shaped, but it can also be substantially elliptical or rectangular in shape to match the circumferential shape of the inner wall of the pump container 23.

[0025] In addition, an elastic spring S is provided between the upper surface of the piston 22 and the upper part of the pump container 23 so that a rod-shaped member is inserted into the upper part of the piston 22. Since the elastic spring S has an urging force in a direction in which the upper surface of the piston 22 and the upper part of the pump container 23 are separated, when a user operates the operation part 21 with a finger against the urging force of the elastic spring S to pull the piston 22 up to the upper part of the pump 2 and then releases the finger from the operation part 21, the urging force of the elastic spring S pushes the piston 22 having the operation part 21 down to the lower part of the pump 2. In this embodiment, the elastic spring S is a coil spring, but in other embodiments, a plate-shaped leaf spring or the like can be used as long as it has an urging force in a direction in which the upper surface of the piston 22 and the upper part of the pump container 23 are separated from each other.

[0026] The piston container 23 has a piston 22 disposed therein, and an intake / exhaust hole 23a is formed at its lower portion. When the piston 22 moves up and down in the pump container 23, air is sucked in and exhausted through the intake / exhaust hole 23a. As shown in Figs. 8 and 9, a communication pipe 4 can be fitted to the outer periphery of the intake / exhaust hole 23a. In addition, a bottom cover 231 is provided at the bottom of the piston container 23, which can close the intake / exhaust hole 23a when not in use, so that foreign matter does not enter the intake / exhaust hole 23a. As shown in Figs. 1, 2, 3, 5, 6, 7, etc., the appearance of the pump container 23 is approximately cylindrical in this embodiment, but in other embodiments, it can be approximately elliptical, approximately rectangular, or approximately hemispherical while maintaining the shape of the cover body 7, and in this case, it can be stored with a neat and refined appearance as in this embodiment.

[0027] The support part 3 is a member that is erected on the upper surface, which is one surface of the pump 2, and can be supported by the user with his / her hand. The user can move the piston 22 up and down with one hand by operating the operation part 21 while placing the user's fingers on the operation part 21 and supporting the support part 3 with the wrist side part such as the ball of the thumb or the ball of the little finger. In order to easily move the piston 22 up and down with one hand, the support part 3 is preferably erected higher than the height of the operation part 21 exposed from the upper surface, which is one surface of the pump 2, from the upper surface of the pump 2. In this embodiment, the support part 3 has a substantially inverted "U" shape, but in other embodiments, it can be other shapes such as a substantially "T" shape, so long as it can be covered by the cover body 7 and does not interfere with the operation of the operation part 21. In this embodiment, the support part 3 is molded integrally with the pump 2, but in other embodiments, it may be molded separately from the pump 2, assembled, and erected on the upper surface, which is one surface of the pump 2.

[0028] The communicating tube 4 is a member that communicates between the intake and exhaust hole 23a of the pump 2 and the air hole 1a of the nasal mucus suction device 1. The communicating tube 4 has a tubular shape of a predetermined length, and acts to transmit the air flow caused by the operation of the pump 2 to the inside of the nasal mucus suction device 1. The communicating tube 4 has a tube hole portion 41 that serves as an air inlet and outlet at both ends, and a tube body portion 42 that characterizes the overall shape of the communicating tube 4. When not in use, that is, when the nasal mucus suction device 1 is not used to suction the nasal mucus of the person to be suctioned, the communicating tube 4 is engaged with the communicating tube engaging portion 5 described later, as shown in FIG. 3. In addition, the communicating tube 4 is preferably 10 cm to 100 cm, more preferably 20 cm to 70 cm, so that the nasal mucus suction device 1 and the pump 2 can be easily operated when in use. Furthermore, since the communicating tube 4 is a member that connects the nasal mucus suction device 1 and the pump 2, it is preferable that it is made of elastic resin such as silicone resin, isoprene rubber, butadiene rubber, etc., so that the nasal mucus suction device 1 can be freely moved. Note that, although the communicating tube 4 has an elongated cylindrical shape in this embodiment, in other embodiments, as long as it is tubular, it can also have a square tube shape with an outer or inner shape such as a square or hexagonal cross section, or a tube shape with an outer or inner shape such as a heart or star cross section.

[0029] The communicating pipe locking portion 5 is a member that is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3, or the inner surface of the cover 7, and locks the communicating pipe 4. The communicating pipe locking portion 5 is at least one selected from, for example, a protrusion that fits with the pipe hole portion 41 of the communicating pipe 4, a hole portion into which the pipe hole portion 41 of the communicating pipe 4 is inserted, or a notch that locks the pipe portion 42 of the communicating pipe 4. The communicating pipe locking portion 5 allows the communicating pipe 4 to be locked and stored when not in use, and prevents the communicating pipe 4 from being lost. Specifically, the protrusion serving as the communicating pipe locking portion 5 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3, or the inner surface of the cover 7 so as to be able to fit with the pipe hole portion 41 of the communicating pipe 4, the hole serving as the communicating pipe locking portion 5 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3, or the inner surface of the cover 7 so as to be able to fit the pipe hole portion 41 of the communicating pipe 4, and the notch serving as the communicating pipe locking portion 5 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3, or the inner surface of the cover 7 so as to be able to lock the communicating pipe 4. As shown in Figs. 3 and 7, in this embodiment, the communicating pipe locking portions 5 are notches provided in two places on the support portion 3, and can lock and store both end sides of the communicating pipe 4, thereby preventing the communicating pipe 4 from being lost.

[0030] The nasal mucus suction device locking part 6 is a member that is provided on at least one of the operation part 21, the upper surface which is one surface of the pump 2, the support part 3, or the inner surface of the cover body 5, and locks the nasal mucus suction device 1. The nasal mucus suction device locking part 6 is at least one selected from, for example, a protrusion that fits with the nasal mucus suction device 1, a hole that fits the nasal mucus suction device 1, or a notch that locks the nasal mucus suction device 1. The nasal mucus suction device locking part 6 allows the nasal mucus suction device 1 to be locked and stored when not in use, and prevents the nasal mucus suction device 1 from being lost. Specifically, the protrusion portion which is the nasal mucus suction device locking portion 6 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3 or the inner surface of the cover body 5 so as to be able to fit into the vent hole 1a or the suction hole 1b of the nasal mucus suction device 1, the hole portion which is the nasal mucus suction device locking portion 6 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3 or the inner surface of the cover body 5 so as to be able to fit the nasal mucus suction device 1, and the notch portion which is the nasal mucus suction device locking portion 6 is provided on at least one of the operation portion 21, the upper surface which is one surface of the pump 2, the support portion 3 or the inner surface of the cover body 5 so as to be able to lock the nasal mucus suction device 1. As shown in FIG. 6, in this embodiment, the nasal mucus suction device locking portion 6 is a hole portion provided on the upper surface which is one surface of the pump 2, into which the lower part of the nasal mucus suction device 1 can be inserted for storage, thereby preventing the nasal mucus suction device 1 from being lost.

[0031] The cover 7 is a member that covers the nasal mucus suction device 1, the operation unit 21, the upper surface which is one surface of the pump 2, and the support unit 3. The cover 7 allows the nasal mucus suction device 1, the upper surface which is one surface of the pump 2, and the support unit 3 to be covered and stored when the nasal mucus suction device 1 is not in use, and prevents the nasal mucus suction device 1 and other components from being lost. As shown in FIG. 1, in this embodiment, the cover 7 has a bottomed cylindrical shape with rounded corners, so that the nasal mucus suction device 1, the operation unit 21, the upper surface which is one surface of the pump 2, and the support unit 3 can be covered. An engagement portion that engages with the upper surface which is one surface of the pump 2 can be provided on the edge of the cover 7 to prevent the cover 7 from falling off. In addition, in this embodiment, the cover 7 is cylindrical with a bottom, and when the cover 7 covers the nasal mucus suction device 1, the operation unit 21, the upper surface which is one surface of the pump 2, and the support unit 3 and is integrated with the pump container 23, the appearance becomes approximately cylindrical, but in other embodiments, the cover 7 may be hollow and open at one end so that the appearance becomes approximately elliptical, rectangular, or semispherical when integrated with the pump container 23 while maintaining the shape and integrity of the pump container 23, and in this case, the cover 7 can be stored with a neat and refined appearance as in this embodiment. In this embodiment, the cover 7 is not perforated so as to cover all of the nasal mucus suction device 1, the upper surface which is one surface of the pump 2, and the support unit 3 when the nasal mucus suction device 1 is not used, but in other embodiments, the cover 7 may have a through hole or be mesh-shaped so that the internal nasal mucus suction device 1, the communication tube 4, etc. can be confirmed.

[0032] The operation of the nasal mucus aspirator 1 of the present invention and a nasal mucus aspirator having the same will be described below.

[0033] As shown in Figures 8 and 9, when suctioning the nasal mucus of a person to be suctioned, the user first connects the nasal mucus suction device 1, the pump 2, and the communicating tube 4, hooks his / her fingers on the operating part 21, and supports the hand by placing the ball of the thumb or the ball of the little finger on the wrist side of the support part 3, and then lifts up the operating part 21. Then, the piston 22 is pulled upward in the pump container 23, and air flows into the pump container 23, and the inside of the nasal mucus suction device 1 is decompressed through the communicating tube 4, and the tip side crack of the first check valve V1 fitted to the upper end of the ventilation tube 121 opens, and the ventilation hole 1a and the suction hole 1b communicate with each other, so that the nasal mucus of the person to be suctioned can be sucked.
