  FIG. 3 is a cross-sectional view for explaining a state in which the nasal cavity device is used. For example, a water absorbent 1 that has absorbed a liquid such as physiological saline is inserted into the nasal cavity 3. The position where the water absorbing body 1 is disposed may be any position within the nasal cavity 3 and may be changed according to the use. The water absorbing body 1 may be arranged so that the water absorbing body is in contact with the deep part of the nasal cavity, for example, the upper nasal passage, the middle nasal passage, and the lower nasal passage, or the portion in front of the nasal cavity, for example, called the nasal vestibule You may arrange the water absorption body 1 in a part. For example, in order to avoid irritation to the nasal mucosa by the water absorbing body 1, it is preferable to arrange the water absorbing body 1 in the nasal vestibule. In addition, in the state which inserted the water absorbing body 1 in the nasal cavity 3, it is preferable to adjust arrangement | positioning of the tubular member 21 so that the tubular member 21 may become a position which does not contact the nasal cavity 3. FIG. This is because it is considered that when the tubular member 21 contacts the nasal cavity 3, nasal discharge discharged from the nasal cavity 3 flows out along the outside of the tubular member 21. In addition, if the water absorbing body 1 is arrange | positioned in a nasal vestibule, it is preferable that the thickness of the water absorbing body 1 is the range from 9 mm to 15 mm, for example, when the thickest part is for adults. If so, the maximum diameter is preferably in the range of 5 mm to 9 mm. The height of the portion excluding the lead-out portion 11 of the water absorbent body 1 is preferably in the range of 10 mm or 25 mm for adults, for example, and in the range of 7 mm to 10 mm for children. It is preferable that

  First, when inserting the water absorbing body 1 of the nasal cavity device into the nasal cavity, the water absorbing body 1 is pushed by the nasal cavity or the like, so that the water absorbing body 1 cannot hold all the liquid absorbed by the water absorbing body 1, and the liquid absorbs water. Try to overflow from body 1. The liquid that has overflowed from the water absorbent body 1 is not discharged from the water absorbent body 1 in the nasal cavity 3, but permeates the lead-out portion 11 having a water absorption equivalent to or higher than that of the water absorbent body 1, so that the inside of the tubular member 21 To be derived. Then, in the tubular member 21, the liquid is discharged to the liquid receiving portion 24 through the inner surface of the tubular member 21 of the liquid discharging structure 2 and the rod-shaped member 22 and is stored in the liquid receiving portion 24.

Similarly, when time passes with the water absorbing body 1 of the nasal cavity device inserted into the nasal cavity 3, nasal discharge or the like is generated, and the liquid tends to overflow from the water absorbing body 1. The liquid is discharged by the liquid discharge structure 2 and stored in the liquid receiving portion 24.
The liquid stored in the liquid receiving part 24 can be easily discharged to the outside by extending the bellows part 241 of the liquid receiving part 24.

  As described above, in the present embodiment, the liquid of the water absorbent body 1 is led out into the tubular member 21 of the liquid discharge structure 2 by the lead-out portion 11 of the water absorbent body 1, and the liquid thus derived is supplied to the tubular member 21. Since the liquid is discharged through the inside, it is possible to prevent the liquid of the water absorbent body 1 from flowing out of the nasal cavity 3 to the skin under the nose. As a result, the liquid discharged from the nasal cavity to the outside can be discharged without touching the skin, and the liquid can be maintained in the nasal cavity hygienically.

  Further, by allowing the water absorbing body 1 to absorb the liquid, the liquid can be held in the nasal cavity 3 and the nasal discharge discharged into the nasal cavity 3 can be discharged from the liquid discharging structure 2. Is possible.

  Therefore, for example, in order to relieve rhinitis, it is conceivable to keep the inside of the nasal cavity 3 in a moist environment. However, when a cotton ball or the like that has absorbed physiological saline is simply inserted into the nasal cavity 3, the time passes. When a large amount of nasal discharge, which is one of the symptoms of rhinitis, occurs, the nasal discharge overflows from the cotton balls and flows along the skin under the nose. For this reason, it is necessary to frequently change the cotton ball or to wipe off the liquid flowing out from the nose, which is difficult to use for a long time or while performing other work.

  However, in the present embodiment, it is possible to keep the inside of the nasal cavity 3 in a moist environment by allowing the water absorbing body 1 of the nasal cavity device to absorb physiological saline and placing it in the nasal cavity 3. By discharging from the liquid discharge structure 2, the nasal discharge does not flow out from the nasal cavity 3, and it is possible to suppress the dirt of the skin due to the nasal discharge, which can be used for a long time or while performing other work. It becomes.

  In the present embodiment, the liquid receiving part of the nasal cavity device may be a liquid receiving part having a tubular structure bent multiple times. For example, the liquid receiving portion of the nasal cavity device may be a liquid receiving portion 41 formed by bending a plurality of vinyl tubes or the like as shown in FIG. By bending the liquid receiving portion in this manner, the overall length of the nasal cavity device can be reduced and handling can be facilitated. The same applies to other embodiments.

  In the present embodiment, the liquid receiving parts of the nasal cavity devices for the left and right nasal cavities may be combined into one container. For example, as shown in FIG. 5, the nasal cavity device may have a structure in which the tubular members 21 of the nasal cavity devices for the left and right nasal cavities are inserted into the two insertion ports 52 of the liquid receiving portion 51. Alternatively, the nasal device may be connected to the tubular member 21 of the nasal device for the left and right nasal cavities, and the combined portion may be used as a liquid receiving portion to store liquid, or the tubular member of the nasal device. They may be coupled to each other by a Y-shaped vinyl tube or the like and coupled to one liquid receiving portion. The same applies to other embodiments.

  In the present embodiment, the nasal cavity device may include a mouth or a mask that covers the mouth and the nose, and the entire or part of the nasal cavity device may be attached to the inside of the mask. For example, as shown in FIG. 6, the entire nasal cavity device may be attached to the inside of a mask 61 that covers the mouth and nose. By configuring the nasal cavity device as shown in FIG. 6, it is possible to prevent the nasal cavity device from being known to others in the nasal cavity. The same applies to other embodiments.

  In the present embodiment, the water absorbent body of the nasal cavity device may be a water absorbent body having a shape in which the lead-out portion and a portion other than the lead-out portion have a step. For example, as shown in FIG. 7, the water absorbing body 70 having a cross-sectional shape in which the lead-out portion 71 and a portion other than the lead-out portion 71 have a step may be used. As an example, the water absorbing body 70 is formed by winding gauze around the rod-shaped member 22. The same applies to other embodiments.

  Moreover, in this Embodiment, the water absorption body of the nasal cavity instrument may have a strip | belt shape of a predetermined width. For example, as shown in FIG. 19, the water absorbing body 1901 may have a belt-like belt-like portion 1902. The water absorbing body 1901 can be realized by, for example, forming a band-shaped gauze around the rod-shaped member 22 and forming a band-shaped portion 1902 without winding a part of the gauze around the rod-shaped member 22. By setting it as such a structure, it is possible to insert the strip | belt-shaped member 1902 of the water absorption body 1901 in the back in a nasal cavity. The belt-like member 1901 may be single or plural. In addition, the material of the belt-shaped member 1901 may be any material as long as it is a material that can be used for the water absorber 1901. The same applies to other embodiments.

  In the present embodiment, a member in place of the tubular member may be used as long as the liquid of the water absorbent body can be discharged without touching the skin or the like. For example, a bowl-shaped member 81 as shown in FIG. 8 may be used. However, in this case, when the nasal cavity device is used, the member 81 needs to be in a position where the liquid led out from the lead-out portion 11 can be received. The same applies to other embodiments.

  Moreover, in this Embodiment, as shown in FIG. 9, you may make it use the water absorbing body 91 which does not have a derivation | leading-out part. In this case, the liquid overflowing from the water absorbing body 91 flows through the rod-shaped member 22 and flows into the tubular member 21. However, in the present embodiment described above, the liquid of the water absorbent body 1 is led out to the tubular member 21 by utilizing the water absorption of the lead-out portion 11 so that the liquid of the water absorbent body 1 does not spill into the tubular member 21. Although it is possible to flow in, when the lead-out portion is not provided as shown in FIG. 9, the liquid in the water absorbing body 91 is formed into water droplets at the time of contact with the rod-shaped member 22 with low water absorption, and the tubular member 21 It is conceivable that some parts will spill before flowing. For this reason, the nasal cavity device having the structure provided with the lead-out portion can obtain a more excellent effect in discharging the liquid of the water absorbing body. The same applies to other embodiments.

  Moreover, in this Embodiment, you may make it a nasal cavity instrument not have a rod-shaped member, as shown in FIG. In this case, a fixing portion 1002 having a shape that can be fitted into the tubular member 21, for example, a diameter that is approximately the same as the inner diameter of the tubular member 21, is provided in a part of the outlet portion 1001 of the water absorbent body 1000. Then, the position of the water absorbing body 1000 may be fixed by fitting the fixing portion 1002 into the tubular member 21. By adopting such a configuration, the rod-shaped member can be omitted and the configuration can be simplified. The same applies to other embodiments.

Thereby, the liquid can be held in the nasal cavity 3 for a long time.

  Further, in the present embodiment, the second lead-out portion 1112 of the water absorbent body 1101 leads the liquid of the water absorbent body 1101 from the opening 11223 at the top of the rod-like member 1122 to the inside of the rod-like member 1122 and is led out. Since the liquid is discharged through the inside of the rod-shaped member 1122, the liquid in the water absorbing body 1101 can be discharged more efficiently.

  Furthermore, in this embodiment, the rod-shaped member 1122 is hollow and has an opening 11223 that communicates with the upper opening of the water absorbent body 1101 and an opening 11224. It makes it easier to breathe through the nose.

  In the present embodiment, it is possible to supply or discharge a liquid such as a chemical solution into the nasal cavity through the rod-shaped member 1122. For example, as shown in FIG. 15, a syringe 1501 is attached to the lower opening portion 11224 of the rod-like member 1122, and by operating these, liquid is injected into the nasal cavity 3 from the opening portion 11224 through the inside of the rod-like member 1122. It is possible to remove the liquid in the nasal cavity 3. Instead of a syringe, a syringe, a pump inlet, or the like may be attached. Even in such a case, even if a large amount of liquid is injected into the nasal cavity 3, the overflowing liquid can be discharged outside the nasal cavity without contaminating the skin under the nose by the liquid discharge structure 1102. It is.

  Moreover, in this Embodiment, as shown in FIG. 16, the rod-shaped member 1122 may penetrate the water absorbing body 1101. With such a configuration, breathing through the nose is facilitated through the inside of the rod-shaped member 1122.

  Further, one or more slits 1701 may be provided on the side surface of the end portion of the rod-shaped member 1122 that is covered with the water absorbent 1101 as shown in the partially cutaway view of FIG. By providing such a slit 1701, the liquid of the water absorbing body 1101 can be discharged through the inside of the rod-shaped member 1122 through the slit 1701 more efficiently. Further, when a liquid is injected into the rod-shaped member 1122 as shown in FIG. 16, the liquid can be directly replenished to the water absorbing body 1101 through these slits 1701. Note that one or more holes may be provided on the side surface of the end of the rod-shaped member 1122 instead of the slit.

Moreover, in this Embodiment, as shown in FIG. 18, you may make it not provide the opening part 11012 in the upper part of a water absorption body. With this configuration, it is somewhat difficult to breathe through the nose through the inside of the rod-shaped member 1122. However, the water-absorbing body 1101 is replenished from the inside of the rod-shaped member 1122, or the liquid of the water-absorbing body 1101 Can be led out to the inside of the rod-shaped member 1122 by the second lead-out portion 1112, and the liquid in the water absorbent body 1101 can be discharged through the inside of the rod-shaped member 1122.
Further, the present invention is not limited to the above-described embodiment, and various modifications are possible, and it goes without saying that these are also included in the scope of the present invention.

The nasal cavity device according to the present invention is suitable as a nasal cavity device that is used by being inserted into the nasal cavity. In particular, the nasal cavity device is useful as a nasal cavity device that holds an electrolyte-containing liquid, a chemical solution, or the like in the nasal cavity.
