[0009] A nasal aspirator according to one embodiment of the present invention will be described with reference to the drawings.

[0010] As shown in Figures 1 and 3, a nasal aspirator 10 according to an embodiment of the present invention comprises a suction unit 12 that generates suction force for aspirating nasal mucus, and a container unit 14 that accommodates and temporarily holds the aspirated nasal mucus. The container unit 14 is detachably connected to the suction unit 12 so that it can be removed from the suction unit 12 after use and easily washed. The container unit 14 and the suction unit 12 are connected via a connection tube 16 that has a predetermined rigidity and is not flexible.

[0011] Here, the total length of the connection tube 16 is preferably 30 mm or more and 60 mm or less. A more optimal range for the total length of the connection tube 16 is 40 mm or more and 50 mm or less. In addition, as an example, the total length of the connection tube 16 is 44 mm. In particular, if the length is 60 mm or more, it becomes difficult for the user to operate the nasal aspirator 10 with one hand, which is unsuitable. The reason why the connecting tube 16 has a predetermined rigidity but no flexibility is to prevent the container part 14, which is positioned on the nose of the person (such as a child) who is to have the nasal aspirator removed from the nose.

[0012] The connection tube 16 is made of FEP (Fluorinated Ethylene Propylene). FEP (Fluorinated Ethylene Propylene) is a type of fluororesin developed after PTFE. FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP), also known as tetrafluoroethylene-hexafluoropropylene copolymer. For example, it is manufactured by DuPont. This increases the rigidity of the connection tube 16, eliminating its flexibility, and enables the container portion 14 to be positioned relative to the suction portion 12. As a result, even if the user does not support the container portion 14 with one hand, the container portion 16 can be prevented from shifting from the nose of the person being suctioned.

[0013] The suction section 12 comprises a syringe 18 having a first opening (not shown) at one end and a second opening 20 at the other end, a piston 24 that moves within the syringe 18 in a direction away from the first opening when the handle 22 is pulled, and an elastic means 26 that biases the piston 24 toward the first opening.

[0014] The syringe 18 has a front wall 28 at one longitudinal end and a rear wall 30 at the other longitudinal end, and is formed into a generally cylindrical shape overall. A frame 32 that can be held by a user is attached to the rear wall 30 of the syringe 18. The first opening is formed in the front wall 28 of the syringe 18. The second opening 20 is formed in the rear wall 30 of the syringe 18.

[0015] The handle 22 and the piston 24 are connected by a shaft 34. An elastic means 26 is disposed around the shaft 34. The piston 24 and the elastic means 26 are housed inside the syringe 18. One longitudinal end of the elastic means 26 abuts against the piston 24, and the other longitudinal end of the elastic means 26 abuts against a rear wall 30 of the cylinder 18. A first opening is formed in the front wall 28 so as to penetrate along the thickness direction, and a second opening 20 is formed in the rear wall 30 so as to penetrate along the thickness direction. The rear wall 30 is detachably attached to the syringe 18.

[0016] One end of the connection tube 16 can be detachably connected to the first opening.

[0017] Although a coil spring is used as the elastic means 26, the present invention is not limited to this.

[0018] The shaft 26 is inserted into the second opening, and the handle 22 is located on the outside of the syringe 18. The handle 22 is composed of a short piece 22A that protrudes slightly from the shaft 34, and a long piece 22B that protrudes slightly from the shaft 34. The length of the handle 22 is formed to be longer than the diameter of the syringe 18. The handle 22 is located inside the frame 32.

[0019] When using the nasal aspirator 10, the user holds the device with the index finger of one hand hooked on the short piece 22A, the middle finger hooked on the long piece 22B, and the thumb hooked on the frame 32, which causes the piston 24 to move in a direction away from the first opening against the elastic force of the elastic means 26. By repeating this action, the container part 14 can suck the mucus from the nose of the person to be suctioned.

[0020] As shown in FIG. 2, the container 14 is generally cylindrical, with a rounded curved surface at one longitudinal end. Specifically, the container 14 is comprised of a rounded container tip 36 and a container body 38 connectable to the tip. A suction port 40 (see FIG. 1) is formed in the container tip 36, through which the mucus passes during suction. A cylindrical inlet tube 42 having a predetermined length is formed inside the container tip 36. The inlet tube 42 communicates with the suction port 40 and serves as a flow path for the aspirated mucus. A cylindrical connector 44 is formed on the outer periphery of the container tip 36. The other end of the connection tube 16 is detachably connected to the connector 44. The connector 44 serves as a flow path for air during suction.

[0021] The container body 38 is cylindrical overall and serves as the reservoir for the suctioned mucus. A male thread 46 is formed at the open end of the container body 38, which can be connected by threading it into a female thread 48 formed at the open end of the container tip 36. The container body 38 does not have a valve or partition, for example. This allows the container 14 to be manufactured at low cost.

[0022] The operation of the nasal aspirator 10 according to one embodiment of the present invention will be described.

[0023] 1 and 5, the connecting tube 16 is highly rigid but not flexible, and its longitudinal length is short, allowing the user to operate the nasal aspirator 10 with one hand. Even when the user is operating it with one hand, the container tip 36 of the container part 14 will not shift from the position of the nose of the person to be suctioned, allowing the mucus to be effectively suctioned from the nose of the person to be suctioned. As a result, when using the nasal aspirator 10, the user can operate the nasal aspirator 10 with one hand while supporting the head of the person to be suctioned with the other hand, making the nasal aspirator operation easier.

[0024] Next, a modified example of the nasal aspirator 10 according to one embodiment of the present invention will be described.

[0025] As shown in Figure 4, in addition to the connecting tube 16 of the nasal aspirator 10, a soft and flexible replacement tube 50 of a predetermined length or more may be prepared, and the connecting tube 16 may be replaced with the replacement tube 50 depending on the application.

[0026] The replacement tube 50 used has a length of, for example, 33 cm (330 mm). The replacement tube 50 is made of, for example, silicone rubber, and has a predetermined flexibility and pliability.

[0027] The replacement tube 50 can also be connected to the suction portion 12 and the container portion 14 in the same manner as the connecting tube 16 .

[0028] It should be noted that the above-described embodiments are merely examples embodying the technical concept of the present invention, and the present invention is not limited to these embodiments, but includes all aspects utilizing the technical concept of the present invention.
