[0003] These appliances are used for the purpose of humidifying the intake air in an environment where the air is dry, such as in an airplane, for example. In addition, the air intake is cleaned by using a filter containing activated carbon or the like to prevent dust and poisoning. Is used as For example, the nasal-mouth outer filter disclosed in Japanese Utility Model Laid-Open No. 62-139548 is a tubular device having an exhaust valve, a heavy filter and an activated carbon layer. At the time of use, it is attached to the nostrils, exhaled from the exhaust valve, and inhaled through the filter, which is effective in dust and gas poisoning.

A humidifying mask disclosed in Japanese Patent Application Laid-Open No. 63-262161 has an inner mask half and an outer mask half each having a breathing hole, and the inner mask half and the outer mask half. And a water-retentive ventilation sheet is sandwiched between them. By using this humidifying mask, it is possible to breathe in a state where air is humidified and to protect the respiratory organ from a dry environment.

A humidifying mask for an aircraft disclosed in Japanese Patent Publication No. 4-52150 is a mask that holds a honeycomb-shaped hygroscopic member in front of the outer nose and has a small space inside the mask. . At the time of use, breathing is performed through the honeycomb-shaped moisture absorbing member. Thereby, the moisture contained in the breath is absorbed and held by the honeycomb moisture absorbing member at the time of expiration, while, at the time of inhalation, the moisture absorbed in the dry inhaled air which is sucked in as outside air is released and sucked back. Dry air could be absorbed.

[0006]

However, the conventional humidifying mask and humidifying mask cover both the nose and the mouth except for the case of Japanese Utility Model Application Laid-Open No. 62-139548. There is a problem such as not being able to eat and drink if left unattended, and feeling uncomfortable when talking. In addition, in the type that is attached to the outer mouth of the nose, there is no cover, so there is no hassle such as removing the mask at the time of eating and drinking, but since the filter is attached to the opening of the nostril, ventilation is not possible. Since it is not enough, there is a problem that the user feels somewhat stuffy when wearing.

Therefore, the nose covering of the present invention provides a nose covering capable of adding functions such as humidification, facilitating breathing, and adding a monitoring device capable of monitoring a respiratory condition. With the goal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments and examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional side view of a nasal covering device according to an embodiment of the present invention.

The nose covering 1 has a cover 3, which covers the entire nose, and is fitted with a mounting means, here a mounting band 15, and is preferably a lightweight one. In the present embodiment, a cylindrical plastic material having a circular bottom surface with a diameter of about 5 cm is used. The cylindrical cover 3 here comprises a main body 5 and a holding portion 7. The main body 5 and the holding portion 7 have a plurality of suction holes 9 on the bottom surface, and the total area of each hole is larger than the cross-sectional area of the nostril. Therefore, the intake can be performed without difficulty.

At the lower surface of the main body 5, two exhaust portions 11 having holes having a larger sectional area than the nostrils are provided at portions corresponding to the respective nostrils, and one end of an exhaust valve 13 is fixed to each of the exhaust portions. It is installed so that it can be opened one side. The exhaust valve uses a sheet thin enough to be easily turned by a nose breath, and for example, polyvinyl chloride and cellophane are suitable. At the time of exhalation, the exhaust valve can easily bend and exhaust, and at the time of inhalation, the exhaust valve closes the exhaust port to encourage intake through a functional ventilation sheet (to be described later).

Further, a ring-shaped mounting band 15 is provided at two places on the side surface of the main body 5. The wearing band 15 is made of elastic rubber in this case, and is worn on both ears like a conventionally used mask.

The holding portion 7 is used by being attached to the outside front of the main body 5. At this time, the functional ventilation sheet 17 is sandwiched between the main body 5 and the holding portion 7, and the moistened functional ventilation sheet 18 is held inside the stopper 6 and mounted inside the main body 5. In the embodiment shown in FIG. 1, the functional ventilation sheet 17 is used for dust prevention. At the time of inhalation, it is possible to clean the outside air that has been contaminated with the dust-proof functional ventilation sheet 17 and further humidify the clean air with the humidification functional ventilation sheet 18 inside the main body to take it into the body.

The functional ventilation sheet 17 or 18 is for protecting, improving or treating internal functions by inhaling the air passing through the sheet, and various types of sheets or sheets according to demand. Various materials that can be formed into a shape can be used. For example, if activated carbon is used, the intake air can be cleaned and dust such as pollen and dust can be prevented from being taken in. Further, even if a fiber member or the like having a myriad of pores is used, pollen and dust can be prevented, which is effective in alleviating the symptoms of allergy. In addition, the use of moistened gauze or moistened fiber members can humidify the inhaled air, prevent the nose from drying, and protect the mucous membrane of the nose, which is prone to inflammation due to the drying. Further, it can be used by impregnating a drug. In this case, since the medicine can be naturally taken into the body by inhalation, it is possible to perform a treatment that is sustained without difficulty. In addition, the functional ventilation sheet may be used in two layers as shown in the embodiment of FIG. 1 if necessary, or only one of the layers may be used. For example, when used as a humidifier at bedtime, if the humidifying functional ventilation sheet 18 is attached to the inside of the main body as in the embodiment of FIG. 1, there is no fear of wetting the bedding.

In another embodiment, the shape of the cover 3 is as follows.
As shown in FIG. 2, it can be created in a nose shape. At this time, if the nostrils adhere to the exhaust part too much, the air from the functional ventilation sheet cannot be functionally performed. Therefore, the protruding part 8 is provided inside the main body under the nose. And FIG.
When the nose cover is worn, the protruding portion 8 is lightly brought into contact with the lower end of the nose, and the wearing band is put on the ear. For this reason, a space is formed between the nostrils and the exhaust portion 11, and the outside air that has passed through the functional ventilation sheet 17 can be taken in through the space. In the case of the shape of the nose covering 1 of FIG.
Since the end of the camera does not enter the field of view, it has a good feeling of wearing, and it is hard to feel a sense of incongruity in appearance.

Further, as another embodiment, as shown in FIG. 3, a structure in which the functional ventilation sheet 17 and the holding portion 7 are sandwiched from the inside of the main body can be used.

In the embodiment shown in FIG. 4, the cover 3 has a cylindrical shape and has a simpler structure. For example, when the functional ventilation sheet 17 is soaked with water or the like, the functional ventilation sheet itself has a certain weight, so that the functional ventilation sheet 17 can be inserted into the cover 3 without a holding portion.

Further, the functional ventilation sheet 17 can be formed into a shape having honeycomb-shaped pores, and can be used for dust and gas poisoning when used in a dry state, and when used in a wet state. Since the moisture can be sufficiently retained in the pores, the moisture retention is good and the humidifying effect can be long lasting.

The holding portion 7 and the main body 5 are mutually locked by a simple hooking or pushing structure, and can be easily removed. Can be replenished. In addition, since the nose covering device 1 has a simple structure and can be mass-produced at low cost, the functional ventilation sheet alone or the entire nose covering device 1 can be disposable as needed.

Further, the above-mentioned mounting means for mounting the cover on the nose can be realized by applying an adhesive to the contact portion of the cover main body with the face in addition to the mounting band. It is more convenient to wear at bedtime than a band.

Further, when humidification is performed by the nose covering device 1, several near-infrared light emitting diodes can be attached to a part of the outside of the cover 3 for use. In this case, the temperature inside the nose covering device 1 increases, and the humidification of the intake air can be more effectively performed by the thermal effect of the near-infrared light emitting diode.

FIG. 5 is a conceptual diagram showing another embodiment of the present invention in which a monitor for detecting the movement of a valve is added.
The monitor device 21 is a device that monitors the movement of breathing from the open / closed state of the exhaust valve 13 provided on the nose covering device 1.

The nose covering device 1 exemplified here has a very simple structure as shown in the embodiment of FIG. 4, and is located at the end of the exhaust valve 13 and the corresponding position of the nose covering device 1, respectively. Attach the contacts to form the sensor 23. Sensor 23
Use a very light and small one that does not hinder the movement of the exhaust valve. The sensor is connected to a discrimination counter by a lead wire, and the discrimination counter receives a second pulse from a clock circuit. The discrimination counter counts the second pulse and is reset by a signal from the sensor 23. If there are 5 second pulses before resetting, that is, if it is 5 seconds or less, it is regarded as normal, and it is not output to the next result counter. Is sent to each counter A or counter B, and the number of times of the signal is displayed on the display device.

The above-mentioned monitor device can monitor a condition called temporary apnea during sleep, which is called apnea syndrome. In this case, if the patient wears the nose covering device 1 before sleep and sets the monitor device, it is possible to know how many seconds and how many times the breathing stopped within a certain time during the overnight sleep. Can be. Further, the monitor device can be used not only for the apnea syndrome, but also for diagnosis of a disease or the like that needs to sense respiration.

[0032]

Since the present invention has the above-described structure, it can cover only the nose to facilitate breathing, and can add functions such as humidification by the functional ventilation sheet. Further, a monitor device for monitoring the movement of the exhaust valve can be added to observe the state of breathing.
