Description

Nasal ventilation improvement equipment

The present invention relates to a nasal ventilation improving device worn on the nose in order to improve nasal ventilation.

Rhinitis symptoms such as nasal congestion may occur due to colds, hay fever, etc. An example of a method for improving rhinitis symptoms such as nasal congestion is the nasal peel-off mask disclosed in Patent Document 1. The nasal peel-off mask in Patent Document 1 is worn on the face and uses its heating element to heat the nasal cavity or sub-nasal cavity, thereby improving rhinitis symptoms.

However, the nasal peel-off mask of Patent Document 1 has a relatively wide wearing area, so some people may feel discomfort when wearing it.

In view of the above circumstances, a technical subject of the present invention is to reduce the wearing area of a nasal ventilation improvement tool worn on the nose for improving nasal ventilation.

The nasal ventilation improving device of the present invention created to solve the above problems is worn on the nose in order to improve nasal ventilation, and the characteristics of the nasal ventilation improving device It includes: a pair of storage parts to store a chemical heat-generating composition; and a connecting part to connect the pair of the storage parts; and the chemical heat-generating composition is a tablet molded body. Here, the so-called tableting molded body is one produced by tableting the raw material. In addition, tablet molding means pressing the raw material using a tablet press to form a tablet shape (the same applies below).

According to this configuration, the chemical heat-generating composition is a tablet molded body, so the volume of the chemical heat-generating composition can be reduced. Therefore, the housing part can be made compact while maintaining the heat generation temperature. Thereby, the wearing area of the nasal ventilation improvement device can be reduced.

In the above structure, the connecting portion may be provided with an elastic member that stretches the side wall of the nose outward when worn.

With this configuration, the nasal cavity can be expanded by the elastic member, thereby improving the effect of eliminating nasal congestion.

In this structure, the distance between the centers of a pair of receiving portions may be 55 mm to 90 mm.

With this configuration, the receiving portion can be placed on an acupuncture point called "Bitong" that is believed to be effective in relieving nasal congestion after stimulation. By doing this, the "nasal passage" can be warmed, thereby improving the effectiveness of eliminating nasal congestion. In addition, when an elastic member is provided at the connecting portion, if the receiving portion is located on the "nose passage", the elastic member can be disposed at a position suitable for stretching the side walls of the nose outward.

According to the present invention, the wearing area of the nasal ventilation improving tool worn on the nose to improve nasal ventilation can be reduced.

Hereinafter, embodiments of the present invention will be described based on the drawings.

1(A) and 1(B) are schematic diagrams showing a nasal ventilation improvement tool according to an embodiment of the present invention. FIG. 1(A) is a schematic plan view, and FIG. 1(B) is a diagram of FIG. 1(A) X-X line schematic cross-sectional view. The nasal ventilation improving tool 1 of this embodiment is worn on the nose in order to improve nasal ventilation, and includes a pair of receiving parts 2 and a connecting part 3 connecting the pair of receiving parts 2 . The pair of storage parts 2 respectively accommodates the chemical heat-generating composition 4 . In addition, the connecting portion 3 is provided with an elastic member 5 that stretches the side walls of the nose outward when worn.

In addition, the nasal ventilation improving tool 1 includes a front sheet member 6 , a back sheet member 7 , an adhesive layer 8 and a peeling member 9 .

The front sheet member 6 has protruding portions 6 a protruding toward the front side at both ends in the longitudinal direction, and the protruding portions 6 a and the back sheet member 7 constitute the accommodating portion 2 . In addition, the elastic member 5 is arranged between the front sheet member 6 and the back sheet member 7 . The front-side sheet member 6 and the back-side sheet member 7 are joined together by, for example, an adhesive (not shown).

The protruding portion 6 a has a circular shape in plan view, and the internal space of the accommodating portion 2 has a substantially cylindrical shape with a low height. Regarding the overall shape of the front sheet member 6, the back sheet member 7, the adhesive layer 8, and the peeling member 9 in plan view, the width gradually increases from the center position in the longitudinal direction to the center position of the accommodation portion 2 in the longitudinal direction. The central position of the receiving portion 2 in the direction is formed into a circular shape closer to the end side.

The adhesive layer 8 is formed on the back surface of the back side sheet member 7 . The peeling member 9 is attached to the back surface of the adhesive layer 8 in a releasable state with respect to the adhesive layer 8 . Furthermore, in this embodiment, the adhesive layer 8 is formed on the entire area of the back surface of the back side sheet member 7, but it may be formed on only a part of the area.

The chemical heating composition 4 is a heating composition used in so-called disposable heating patches (chemical heating patches). This chemical heating composition 4 utilizes the oxidation heat of metal. It generally contains metal powders such as iron powder, metal halides such as salt, water, activated carbon powder and water-retaining materials. In addition, the chemical heat-generating composition 4 may further contain a temperature control agent that controls the maximum heat generation temperature (for example, refer to Japanese Patent No. 6273481).

The chemical heat-generating composition 4 is a tablet-molded body produced by tablet-molding raw materials. The shape of the tablet molded body is a low-height substantially cylindrical shape (circular shape in plan view) that is combined with the shape of the internal space of the accommodating portion 2 . However, the shape of the tablet molded body is not limited to this, and may be, for example, a prism shape.

The area of the chemical heating composition 4 in plan view is, for example, 200mm ² to 500mm ² , more preferably 250mm ² to 450mm ² , and most preferably 300mm ² to 400mm ² . When the area of the chemical heating composition 4 in plan view is less than 200 mm ² , the nasal congestion eliminating effect may not be sufficiently obtained. When the area of the chemical heat-generating composition 4 in plan view exceeds 500 mm ² , a large amount of the chemical heat-generating composition 4 is required and the manufacturing cost may increase.

The front sheet member 6 and the back sheet member 7 are made of a breathable material, such as nonwoven fabric using polyethylene, polypropylene, or the like. In this embodiment, the front side sheet member 6 and the back side sheet member 7 are made of the same material, but may be made of different materials.

The moisture permeability of the front and back sheet members 6 and 7 is, for example, 600g/(m ² .24h)~20000g/(m ² .24h), more preferably 1000g/(m ² .24h)~10000g/(m ² .24h), the best is 2000g/(m ² .24h)~8000g/(m ² .24h). Here, the definition of water vapor transmission rate (water vapor transmission rate) is based on Japanese Industrial Standards (JIS) K 7129 (the same applies below).

When the moisture permeability is less than 600g/(m ² .24h), the chemical heating composition 4 may not be able to heat up quickly and may not be able to quickly eliminate nasal congestion. When the moisture permeability exceeds 20000g/(m ² .24h), the exothermic reaction of the chemical exothermic composition 4 may proceed excessively and the exothermic time may be shortened.

Characteristics related to the heat generation temperature (temperature on the skin side) include rise time (in this embodiment, the time from 31.5°C to 39.9°C), maximum temperature, and duration (in this embodiment, the time until it reaches 40°C or above). period of time). Here, the measurement method of the heating temperature is the "normal method" in accordance with JIS S 4100 (the same applies below).

For example, the rise time is preferably within 60 seconds, more preferably within 50 seconds, and most preferably within 40 seconds. If the rising time exceeds 60 seconds, it may be difficult to quickly eliminate nasal congestion after wearing the nasal ventilation improvement device 1.

The maximum temperature is, for example, preferably 43°C to 65°C, more preferably 43°C to 60°C, and most preferably 43°C to 55°C. When the maximum temperature is less than 43°C, approximately 43°C required for good blood flow cannot be reached. When the maximum temperature exceeds 65°C, there is a possibility of low-temperature burns and the heating time may be shortened.

For example, the duration is preferably 10 minutes to 3 hours, more preferably 10 minutes to 2 hours, and most preferably 10 minutes to 1 hour. If the duration is less than 10 minutes, the nasal congestion relief effect may not be fully obtained. If the duration exceeds 3 hours, there is a possibility of low-temperature burns, and a large amount of the chemical heating composition 4 is required, which may increase the manufacturing cost.

In this embodiment, the chemical heat-generating composition 4 passes through the front side of the accommodating part 2 The protruding portion 6a of the sheet member 6 comes into contact with the air, and therefore the protruding portion 6a serves as a ventilation portion for bringing the chemical heat-generating composition 4 into contact with the air.

The shape or material of the elastic member 5 is not particularly limited as long as it can stretch the side walls of the nose outward when worn. In the illustration examples of FIGS. 1(A) and 1(B) , the elastic member 5 has a long plate shape and is rectangular in plan view. In addition, as the material of the elastic member 5, for example, synthetic resin such as polyester can be used.

The distance d between the centers of the pair of receiving portions 2 (chemical heating compositions 4) in plan view is, for example, 55 mm to 90 mm, more preferably 60 mm to 85 mm, most preferably 65 mm to 80 mm. Regardless of whether the distance d is less than 55 mm or exceeds 90 mm, it may be difficult to place the receiving part on an acupuncture point called "Natong" that is thought to be effective in stimulating nasal congestion.

The nasal ventilation improving tool 1 is placed inside a bag (not shown) made of non-breathable material before use, and is sealed and stored. When using the nasal ventilation improving tool 1, take the nasal ventilation improving tool 1 out of the bag, peel off the peeling member 9 on the back side, and wear it by attaching the adhesive layer 8 to the nose as shown in Figure 2 . In the illustrated example, the center of a pair of receiving portions 2 (chemical heating compositions 4) is placed on an acupuncture point called "nasitong".

In the nasal ventilation improving tool 1 of the present embodiment configured as described above, the chemical heating composition 4 is a tablet molded body, so the volume of the chemical heating composition 4 can be reduced. Therefore, the housing part 2 can be made compact while maintaining the heat generation temperature. Thereby, the wearing area of the nasal ventilation improvement tool 1 can be reduced.

The present invention is not limited to the above-described embodiments and can be made within the scope of its technical ideas. various transformations within the perimeter. For example, in the above embodiment, the chemical heat-generating composition 4 is accommodated between the protruding portion 6a of the front sheet member 6 and the back sheet member 7. However, as shown in FIG. 3(A), the chemical heat-generating composition 4 may be accommodated in advance. The breathable bag member 10 of the heat-generating composition 4 is accommodated between the protruding portion 6 a of the front sheet member 6 and the back sheet member 7 . In this case, the bag member 10 , the protruding portion 6 a and the back sheet member 7 serve as a storage portion for accommodating the chemical heat-generating composition 4 , and the bag member 10 and the protruding portion 6 a serve as a vent for bringing the chemical heat-generating composition 4 into contact with the air. department.

In addition, as shown in FIG. 3(B) , the breathable bag member 10 containing the chemical heating composition 4 in advance may be attached to the front sheet member 6 using the adhesive layer 11 on the back side and fixed thereto. In this case, the bag member 10 serves as a storage portion for accommodating the chemical heat-generating composition 4, and the bag member 10 serves as a ventilation portion for bringing the chemical heat-generating composition 4 into contact with air. In addition, in this case, the front sheet member 6 and the back sheet member 7 may be made of a non-breathable material.

Furthermore, in this case, before using the nasal ventilation improving tool 1, a peeling member (not shown) is attached to the adhesive layer 11 of the bag member 10, and the bag member 10 is put into a bag made of non-breathable material (not shown). (shown in the figure) and sealed for storage. When using the nasal ventilation improvement tool 1, the bag member 10 can be taken out from the bag body, peeled off the peeling member, and attached to the front side sheet member 6 and fixed.

[Example 1]

The inventor of this application evaluated the heating temperature of the chemical heating composition 4 associated with the nasal ventilation improving tool 1 of the present invention.

Sample S used in the evaluation and the above-mentioned embodiment (refer to Fig. 1(A), 1(B)), as shown in FIGS. 4(A) and 4(B), it is provided with a storage part 2 that houses the chemical heat-generating composition 4, and does not include the connecting part 3 and the elastic member 5. In other respects, since they are the same as those in the above-mentioned embodiment, the same components are denoted by the same reference numerals, and detailed descriptions are omitted. Furthermore, during evaluation, the peeling member 9 is peeled off, and the sample S is placed on the measuring device with the adhesive layer 8 interposed therebetween.

The chemical heating composition 4 uses a cylindrical tablet molded body. The weight of the tableting molded body is 1g, the diameter is 15mm, and the height is 5mm. The chemical heating composition 4 consists of 30% to 40% iron powder, 1% to 5% salt, 20% to 30% water, 1% to 5% activated carbon powder, 10% to 20% by weight of water-retaining material, 10% to 20% by weight of temperature control agent.

The moisture permeability of the front side sheet member 6 and the back side sheet member 7 is 8000g/(m ² .24h).

Using the temperature measurement sensor ST-22E-005-TS3-WT4 (manufactured by Adachi Keiki Co., Ltd.) and the graphic recorder KR2S2P-NOA (manufactured by CHINO Co., Ltd.), the heating temperature (skin side) of 10 samples S was measured. temperature). As the heat generation characteristics, the rise time (in this example, the time from 31.5°C to 39.9°C), the maximum temperature, and the duration (the time until the temperature reaches 40°C or higher) were measured. The results are shown in the table below. In addition, FIG. 5 shows the heating temperature with respect to time as an average value of 10 samples S.

According to the above table, the rise time of any sample S is within 40 seconds. In addition, it can be seen from Figure 5 that the time until reaching the maximum temperature is within 5 minutes. Compared with ordinary chemical heating patches, this time is very short. The reason for this result is considered to be that the moisture permeability of the nonwoven fabric constituting the bag is as high as 8000 g/(m ² .24 h), so the chemical heat-generating composition quickly comes into contact with the air and the temperature of the chemical heat-generating composition rises rapidly.

[Example 2]

In addition, the inventor of the present application conducted a functional test related to the nasal ventilation improving tool 1 of the present invention.

In this functional test, the same sample S as used in Example 1 was used. The subjects were 15 people who had symptoms of nasal congestion while sleeping.

The test method is as follows. Sample S was worn on the "Breathe Right" on the subject's face, and a commercially available product ("Breathe Right" (registered trademark/Glaxo SmithKline Consumer Healthcare Japan) (manufactured by Co., Ltd.) was worn on the nose of the subject. That is, the sample S and the commercial product are equivalent to the embodiments of the present invention. For comparison, the sample S was not worn and the commercial product was worn on the nose of the subject. The above situation is also tested.

Set the state of completely no nasal congestion to 0.00, and set the state of completely blocked nose to The status was set to 1.00, and the subject was asked to numerically quantify the degree of nasal congestion through the "Visual Analogue Scale (VAS)".

The degree of nasal congestion was quantified immediately before wearing, after 5 minutes, and after 10 minutes for breathing through both nostrils, breathing through the left nostril only, and breathing through the right nostril only. However, when only one nostril is used for breathing, one nostril is distinguished based on the difference between the nostril with the stronger nasal congestion and the nostril with the weaker nasal congestion, not the difference between the left and right nostrils.

The test results are processed as follows. The value indicating the degree of improvement of nasal congestion was calculated by subtracting the value immediately before wearing the product from the value after 5 minutes and 10 minutes. This calculated value is negative, and the larger its absolute value is, the more the nasal congestion is improved. Graphs of the average values of the calculated values are shown in FIGS. 6 to 8 . Figure 6 shows a case where two nostrils are used for breathing, Figure 7 shows a case where only one nostril with stronger nasal congestion is used for breathing, and Figure 8 shows a case where only one nostril with weak nasal congestion is used for breathing. In addition, in any figure, a solid line shows the case where sample S and a commercial product are used together, and a dotted line shows the case where only a commercial product is used.

From Figures 6 to 8, it can be seen that in any case of breathing through both nostrils, breathing through only one nostril with stronger nasal congestion, or breathing through only one nostril with weak nasal congestion, at the same time When using sample S and the commercial product, nasal congestion was improved. In particular, as shown in FIG. 7 , when only one nostril with stronger nasal congestion is used for breathing, the nasal congestion is significantly improved compared to the case of using only a commercial product.
