Description

  The present invention relates to a health care patch sheet using a functional element that emits infrared rays and charged particles, and more particularly to a health care patch sheet using nanodiamond semiconductor particles.

Conventionally, as a medical device, one using magnetic field lines, infrared rays, and charged particles has been proposed.
Here, as the magnetic field lines, those using ferrite, R-Co magnets, or the like having a magnetic force of 400 G or more are known as having a blood flow enhancement effect.
Infrared rays are known to have a thermal effect, using germanium (Ge) having a wavelength of 4 to 10 μm, black quartz, tourmaline, or the like.
Further, charged particles that use tourmaline and germanium particles are known as those that generate a bioelectric current and have a blood flow enhancement effect.

Among these, tourmaline and germanium are widely used, but have various problems.
For example, tourmaline emits an infrared wavelength having a wavelength of 4 to 10 μm, which has a large thermal effect. However, since it is an insulator, the number of excited carriers (charged particles) that radiate infrared rays is small in thermal excitation at a body temperature. A sufficient amount cannot be secured.

  In addition, charged particles generated by the piezoelectric pyroelectric effect of tourmaline, which is an insulator, are observed when the tourmaline is heated by the body temperature and the crystal body is distorted, or the temperature difference between the body temperature and the health care device continues to change. It occurs when crystals are distorted. Therefore, when used in a health care device, etc., when the entire temperature becomes steady after being attached to the human body, the piezoelectric pyroelectric material electrically belongs to the insulator, so that the amount of emitted charge is drastically reduced and charged. The effect of the particles can no longer be expected.

  On the other hand, germanium has a large charged particle radioactivity because it is a semiconductor, but since the wavelength of infrared rays emitted from an activation energy level of 0.01 eV due to the semiconductor band structure is as large as 100 μm, the thermal effect of infrared rays is small. For this reason, the charge penetration effect in the composite magnet type using conventional infrared rays and charged particles is hardly expected.

  Germanium releases charged particles by heating at about body temperature, but if the semiconductor is in a bulk state, the electromotive force due to the Seebeck effect generated by the temperature difference of germanium crystals due to body temperature heating is about 1 mV at the maximum. On the other hand, since the impedance of the human body is as large as several hundred Ω, the effect of the charged particles penetrating into the human body is small. For this reason, the effect as a health care device cannot be expected.

JP 05-347206 A

  The present invention has been made in order to solve such problems of the prior art, and the object of the present invention is to efficiently generate excited charged particles of nanodiamond semiconductor particles by a low temperature heating of about a body temperature with a large generated potential. An object of the present invention is to provide a health care patch sheet that can penetrate into the human body for a long time and obtain a synergistic effect with the infrared radiation from the nanodiamond semiconductor particles.

The present invention made to achieve the above object has a sheet substrate and a charged particle generation layer made of a composite material provided on the sheet substrate and having nanodiamond semiconductor particles dispersed in a polymer resin. The charged particle generating layer is a health care patch sheet provided in a pattern on the surface of the sheet base material.
In the present invention, the charged particle generation layer is provided on one surface of the sheet base material, and the other surface of the sheet base material is provided with a mounting surface for mounting the sheet on an object to be pasted. It is also effective when it is.
In the present invention, the sheet base material is also effective when a pattern support layer is provided on one surface and a mounting surface is provided on the other surface.
In the present invention, it is also effective when the charged particle generation layer is composed of a plurality of stripe patterns.
In the present invention, it is also effective when the charged particle generation layer has a lattice pattern.
In the present invention, the charged particle generation layer is also effective when it is composed of a plurality of concentric patterns.
In the present invention, it is also effective when the charged particle generation layer has a continuous spiral pattern.
Further, the present invention provides a sheet base material provided with a pattern support layer on one surface, and a composite material in which nanodiamond semiconductor particles are blended in a polymer resin, on the sheet base material, It is a method for manufacturing a health care medical patch sheet having a step of providing a charged particle generation layer made of a composite material.
In this invention, it is effective also when it has the process of providing the said charged particle generation layer on the said sheet | seat base material by a screen printing method.

  Nanodiamond semiconductor particles used in the present invention are easily converted into n-type or p-type semiconductors by actively doping nitrogen (N), boron (B), or the like during synthesis. Since the solid band structure is disturbed due to the influence of strain and the like, it has an activation energy level of 0.3 to 0.5 eV, and the number of excited carriers is overwhelmingly larger than that of an insulator such as tourmaline.

As a result, such a nanodiamond semiconductor particle has a large rate of change in conductance (reciprocal of resistance) in the temperature region near body temperature, that is, a rate of change in electrical resistance, as shown in FIG. high.
Here, nanodiamond semiconductor particles doped with boron (B) and having an activation energy level of 0.36 eV.

FIG. 2 shows the infrared spectral radiation characteristics of nanodiamond semiconductor particles and tourmaline. In this case, 10% by weight of nanodiamond semiconductor particles and 50% by weight of tourmaline are blended in polypropylene (PP) as the polymer matrix resin. The measurement temperature is 40 ° C.
As shown in FIG. 2, the nanodiamond semiconductor particle is a bio-infrared ray radiated from an activation energy level of 0.3 to 0.5 eV even though the compounding ratio of the particle in the composite is 1/5 of tourmaline. Infrared radiation ability in a wavelength band (4-15 micrometers) is large.

As can be understood from FIGS. 1 and 2, nanodiamond semiconductor particles have a larger biological temperature effect than conventional techniques because charged particle radioactivity near body temperature and radioactivity in the bioinfrared wavelength band are larger than tourmaline. Can do.
In the case of the present invention using such nanodiamond semiconductor particles, since the charged particle generating layer containing nanodiamond semiconductor particles is provided on the sheet base material, the health care patch sheet is long, for example, on the point of the human body. Can paste time.

As described above, the nanodiamond semiconductor particles used in the present invention have an overwhelmingly large number of excited carriers when heated at a low temperature of about 36 ° C. by body temperature as compared with an insulator such as tourmaline. A large thermoelectromotive force is generated due to (Seebeck effect).
Therefore, according to the present invention, the charged particles excited from the nanodiamond semiconductor particles can be efficiently penetrated into the human body as compared with the case where conventional tourmaline or germanium is used, and a large bioelectric current is generated to increase blood flow. Can be made.

  Further, according to the present invention, due to the heating effect due to body temperature and the cooling effect due to the outside air, a temperature difference occurs between the nanodiamond semiconductor particles, and charged particle emission and infrared radiation continue while being applied to the human body. For example, compared to the case where nanodiamond semiconductor particles are woven into clothing or the like and worn on the human body, the biological temperature effect can be efficiently generated over a long period of time.

  In the present invention, the charged particle generation layer is provided on one surface of the sheet base material, and the other surface of the sheet base material is provided with a mounting surface for mounting the sheet on an object to be pasted. In this case, the temperature difference between the charged particle generation layer containing the nanodiamond semiconductor particles and the surface of the human body is large at the beginning of the contact by fixing the mounting surface of the sheet base material in contact with the surface of the human body. Because the heat from the surface of the human body is transferred to the charged particle generation layer through the sheet base material, the amount of heat generated due to the thermoelectric effect compared to when the top surface of the charged particle generation layer is in contact with the surface of the human body Can be bigger.

  On the other hand, in order to produce a health care patch sheet according to the present invention, a sheet base material in which a pattern support layer is provided on one surface, and a composite material in which nanodiamond semiconductor particles are blended in a polymer resin are prepared. The charged particle generation layer made of the composite material may be provided on the sheet base material by a printing method, for example, and a complicated process is not required.

  According to the present invention, the generated potential is large, and the excited charged particles of the nanodiamond semiconductor particles by low temperature heating at about body temperature can efficiently penetrate into the human body for a long time, and a synergistic effect with the infrared radiation from the nanodiamond semiconductor particles can be obtained. Therefore, the living body temperature effect can be efficiently generated over a long time.

As shown in FIGS. 3A and 3B, the health care patch sheet 1A of the present embodiment is laminated on, for example, a base 2 made of a sheet-like base material and one surface of the base 2. A sheet base material 5 including the pattern support layer 3 is provided, and a charged particle generation layer 4 </ b> A is provided on the pattern support layer 3 of the sheet base material 5.

Here, as the base 2, it is preferable to use a stretch film, a nonwoven fabric, or a fabric.
In the present invention, the material of the base 2 is not particularly limited, and for example, a polyester resin such as PET, a polyurethane resin, an elastomer, or the like can be suitably used.
In particular, it is preferable to use a composite film having PET (polyethylene terephthalate) as the base 2 from the viewpoint of safety to the human body and easy availability.

The thickness of the base 2 is not particularly limited, but is preferably set to 30 to 100 μm from the viewpoint of reliably supporting the pattern support layer 3 and the charged particle generation layer 4A.
As the shape of the base 2, various shapes can be employed.
For example, a rectangle (triangle, quadrangle, polygon), circle, ellipse, and the like can be given.

In addition, as shown to Fig.3 (a), when the shape of the base 2 is a rectangle (quadrangle), from the viewpoint of making it hard to peel from the human body which is a to-be-adhered body, the corner | angular parts 2a-2d are rounded (curved). More preferably, it is formed into a shape.
Moreover, the magnitude | size of the base 2 is not specifically limited as long as it can affix on the surface of a human body.

The pattern support layer 3 is preferably provided on the entire surface of one side of the base 2.
The polymer resin that is the material of the pattern support layer 3 is not particularly limited, but from the viewpoint of ensuring adhesion with the charged particle generation layer 4A, an ethylene-vinyl acetate copolymer (EVA) is used. More preferably, it is used.
The thickness of the pattern support layer 3 is not particularly limited, but is preferably 30 to 50 μm from the viewpoint of reliably supporting the charged particle generation layer 4A.
In addition, the film with which the pattern support layer 3 was formed on the base 2 used for this invention is marketed variously, and can be obtained easily.

In the present invention, the charged particle generation layer 4A is composed of a charged particle generator described below.
The charged particle generator used in the present invention is made of a composite material in which nanodiamond semiconductor particles are mixed with a binder made of an electrically insulating polymer resin.
Examples of the polymer resin used in the matrix of the charged particle generator in the present invention include polyester-based, acrylic-based, and urethane-based polymer materials.

Among these, it is more preferable to use a polyester-based polymer resin material from the viewpoint of ensuring adhesion with the pattern support layer 3 and being suitable for the screen printing method.
An elastomer such as a synthetic rubber can also be used as the matrix of the charged particle generator.

As the nanodiamond semiconductor particles used in the present invention, semiconductor carbon particles having SP ³ and SP ² composite structures synthesized by shock waves such as CB explosives can be suitably used.
Specific examples of a method for obtaining semiconductor composite carbon particles having SP ³ and SP ² structures synthesized by shock waves include the following two methods.

(1) A method of synthesizing semiconductor carbon particles having a composite structure by exploding high-performance CB explosives in a closed container and instantaneously generating temperatures of 2 million atmospheres and several thousand degrees (Eiji Osawa Japan Nanonet Bulletin 108 2006 .03.08), (2) As an indirect method, for example, a raw material in which a boron compound and graphite are mixed is used, and iron is ejected by the power of explosives and collided with this raw material, and a shock wave generated at that time is used for synthesis. However, the indirect method (2) is more preferable because it is less susceptible to explosives, and nanodiamond semiconductor particles having a high compounding ratio between the boron compound and graphite can be obtained.

In addition, the nanodiamond semiconductor particles used in the present invention can be produced by actively doping nitrogen (N), boron (B) or the like during production.
The size (average particle size) of the nanodiamond semiconductor particles used in the present invention is preferably in the range of 3 nm to 1 μm.
When the size of the nanodiamond semiconductor particles is less than 3 nm, the band structure as a semiconductor is disturbed. On the other hand, when the size exceeds 1 μm, the repulsive action between the excited charged particles in the nanodiamond semiconductor particles becomes strong, and the charged particles are one-dimensional. The potential difference in the semiconductor particles is reduced.

Note that nanodiamond semiconductor particles having an SP ³ structure synthesized by shock waves have a basic particle size of 3 to 10 nm, and have an advantage that a pulverization step after molding is unnecessary.
The charged particle generator used in the present invention, for example, mixes one or two or more polymer resins as a matrix and nanodiamond semiconductor particles and then dissolves them using an organic solvent to obtain a printing ink. And using this printing ink, the charged particle generation layer 4A of the pattern shape mentioned later is provided on the pattern support layer 3 of a base material.

Confirmed by the inventor. In this case, the present inventors have also confirmed that the aggregated particle aggregate is exposed from the surface of the pattern support layer 3.

In the case of the present invention, the blending amount of the nanodiamond semiconductor particles in the charged particle generator is not particularly limited, and the thermoelectric effect increases as the blending amount increases, but it may be 20 wt% or more and 50 wt% or less. preferable.
When the blended amount of the nanodiamond semiconductor particles in the charged particle generator is less than 20% by weight, it is difficult to obtain the required thermoelectric effect. On the other hand, when it exceeds 50% by weight, the charged particle generator tends to become brittle. Become.

Further, the pitch between the patterns 40 of the charged particle generation layer 4A (the distance between the central portions of the adjacent patterns 40) is set in consideration of the width of the pattern 40 of the charged particle generation layer 4A. The thickness is preferably from 0.5 mm to 3.0 mm, and more preferably from 1.0 mm to 2.0 mm.
When the pitch between the patterns 40 of the charged particle generation layer 4A is less than 0.5 mm, the cost is high. On the other hand, when the pitch exceeds 3.0 mm, the thermoelectric effect may not be generated.

On the other hand, the height of the pattern 40 of the charged particle generation layer 4A is preferably 5 μm or more and 20 μm or less, and more preferably 10 μm or more and 15 μm or less.

Since the charged particles can be efficiently penetrated into the human body, a large bioelectric current can be generated and blood flow can be enhanced.

  In addition, according to the present embodiment, a temperature difference occurs between the nanodiamond semiconductor particles due to the heating effect due to body temperature and the cooling effect due to outside air, and charged particle emission and infrared radiation while being applied to the surface 10 of the human body. Therefore, the living body temperature effect can be efficiently generated over a long period of time compared to, for example, the case where nanodiamond semiconductor particles are woven into clothing or the like and worn on the human body.

  Further, as shown in FIG. 5C, when the back surface of the base 2 of the sheet base material 5 is brought into contact with the surface 10 of the human body, the charged particle generation layer 4A containing the nanodiamond semiconductor particles and the human body at the beginning of the contact. And the heat from the human body surface 10 is transferred to the charged particle generation layer 4A through the base 2 and the pattern support layer 3 of the sheet base material 5, and thus the charged particle generation layer 4A Since the temperature rise time is longer than that when the charged particle generation layer 4A of the sheet base material 5 is brought into contact with the human body, and the charged particle generation layer 4A is continuously cooled by the atmosphere, FIG. Compared with the case where the top surface of the charged particle generation layer 4A of the health care patch sheet 1A is in contact with the surface 10 of the human body, the amount of heat generated due to the thermoelectric effect can be increased.

EXAMPLES Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to these Examples.
First, a polyester resin is used as a polymer resin, and nanodiamond semiconductor particles (trade name SCM Nanodiameter manufactured by Sumiishi Materials Co., Ltd .: basic particle size 3-8 nm) manufactured by the above indirect method are used as semiconductor particles. A sample of charged particle generator was prepared.

In this case, first, 43% by weight of the above-mentioned nanodiamond semiconductor particles were added to the polyester resin for ink, and xylene was used as a solvent, and the polyester resin was dissolved at room temperature to prepare an ink for screen printing.
A 270-mesh screen was used as the screen plate, and a charged particle generation layer having a predetermined pattern was formed on the sheet substrate using the ink described above.
In addition, when a 270 mesh screen plate is used, the present inventors have confirmed that only nanodiamond semiconductor particles (aggregates) of about 6 μm or less are used for pattern formation.

In this example, as the sheet base material, a commercially available film (thickness: 100 μm, trade name: Thermal Lami Film manufactured by HEIKO Co., Ltd.) in which an EVA layer is laminated on PET is used, and on the EVA layer of the sheet base material, the thickness is A pattern having a predetermined shape of 10 μm was formed and dried.
9 to 12 show the shape of the pattern of the sample used in this example.

Here, FIG. 9 shows a pattern in which a striped pattern 40 is formed on the sheet substrate 5, and Sample 1-1 (5-1) has a width of 0.3 mm and a pitch (adjacent pattern 40 of each pattern 40). The distance between the central portions of each pattern 40 is 1 mm, the sample 1-2 (5-2) has a width of 0.5 mm for each pattern 40, the pitch 1 mm, and the sample 1-3 (5-3) has a width 1 for each pattern 40. 0.0 mm and pitch 2 mm.
The length of each pattern 40 in FIG. 9 was set to 27 mm.

FIG. 10 shows a lattice-shaped pattern 41 formed on a sheet base material 5. Sample 2-1 (6-1) has a width of 0.3 mm for each pattern 41 and a pitch (a central portion of adjacent patterns 41). (Distance between) is 1 mm, sample 2-2 (6-2) is 0.5 mm in width of each pattern 41, pitch is 1 mm, sample 2-3 (6-3) is 1.0 mm in width of each pattern 41, The pitch was set to 2 mm.
In addition, the length of the frame part of each pattern 41 of FIG. 10 was set to 30 mm.

  FIG. 11 shows a case in which a concentric pattern 43 is formed on the sheet substrate 5, and the sample 3-1 (7-1) has a width of 0.3 mm for each pattern 43 and a pitch (the central portion of the adjacent pattern 43). (Distance between) is 1 mm, sample 3-2 (7-2) is 0.5 mm in width of each pattern 43, pitch 1 mm, sample 3-3 (7-3) is 1.0 mm in width of each pattern 43, The pitch was set to 2 mm.

FIG. 12 shows a pattern in which a spiral pattern 44 is formed on a sheet base material 5. Sample 4-1 (8-1) has a width of 0.3 mm for each pattern 44 and sample 4-2 (8-2). The width of each pattern 44 was set to 0.5 mm, and the width of Sample 4-3 (8-3) was set to 1.0 mm.
Note that the pitch of each pattern 44 in FIG. 12 (the distance between the central portions of adjacent patterns 44) is set so as to decrease stepwise from the outer peripheral portion of the pattern 44 toward the inside. Specifically, , About 2 mm to about 1 mm.

Samples having the patterns shown in FIGS. 9 to 12 were respectively attached to the human arm using an adhesive tape, and the temperature change of the skin surface portion was measured.
Prior to this measurement, only the above-described sheet base material 5 was attached to the arm part of the human body, and the temperature change of the skin surface portion was measured, but no temperature change was observed.

Moreover, temperature measurement was performed at room temperature (about 25 degreeC), and the measurement part was cooled with cold water before mounting each sample on the arm part of a human body.
Furthermore, in the present embodiment, for example, as shown in FIG. 4C, when the charged particle generation layer 4A of the sheet substrate 5 is brought into contact with the surface 10 of the human body, for example, as shown in FIG. In addition, the measurement was performed separately when the charged particle generation layer 4A of the sheet base material 5 was not brought into contact with the surface 10 of the human body and the back surface of the base 2 of the sheet base material 5 was brought into contact with the human body surface 10.

On the other hand, for temperature measurement, a non-contact infrared radiation thermometer (trade name FSV-7000E, manufactured by Apiste) was used, and the skin surface temperature at the center of each pattern and the temperature of the skin surface around the sample were 10 Measured every second.
Then, the skin surface temperature at the center of each pattern and the temperature difference between the skin surfaces around each sample were calculated, and the maximum value of the temperature difference and the time to reach the maximum value were calculated. The results are shown in Tables 1 and 2.

  As is clear from Tables 1 and 2, in most of the samples described above, a temperature increase was observed at the central portion of the pattern of the sample attached to the arm. Thereby, it is understood that the biological current is increased by the mounting of the sample, and the biological temperature effect is obtained.

And, compared with the case where the charged particle generation layer of the sheet base material is brought into contact with the human body, the case where the base back surface of the sheet base material is brought into contact with the human body is the pattern center portion of the sample attached to the arm portion. The temperature rise tends to increase.
In this case, when the charged particle generation layer of the sheet base material is brought into contact with the human body, the time to reach the maximum value of the skin surface temperature at the center portion of the pattern and the temperature difference between the skin surfaces around each sample, A short tendency is seen compared with the case where the base back surface of a sheet base material is made to contact a human body.

  In particular, in Sample 1-1 and Sample 1-2 among samples in which a striped pattern is formed on a sheet base material, when the charged particle generation layer of the sheet base material is brought into contact with a human arm, the skin Whereas the temperature rise of the surface was not observed, when the base of the sheet base material was brought into contact with the human arm for the same sample 1-1 and sample 1-2, the temperature of the skin surface of the arm was 2 It has risen by about ℃.

  In addition, when a concentric pattern is formed on the sheet base material, and even when the same spiral pattern is formed on the sheet base material, when the base of the sheet base material is brought into contact with the human body, Compared with the case where the charged particle generating layer of the sheet base material is brought into contact with the human body, the temperature rise in the central portion of the pattern of the sample attached to the arm portion tends to increase.

  For example, for a sample in which a concentric pattern is formed on a sheet substrate, when the charged particle generation layer of the sheet substrate is brought into contact with the human body, the skin surface temperature at the center of the pattern and the surroundings of each sample Whereas the maximum value of the temperature difference on the skin surface is 1.48 ° C. (Sample 3-3), when the back surface of the base of the sheet base material is brought into contact with the human body, the maximum value of the temperature difference is 1. The temperature rises to 80 ° C. (Sample 7-3).

  In addition, regarding a sample in which a spiral pattern is formed on a sheet substrate, when the charged particle generation layer of the sheet substrate is brought into contact with the human body, the skin surface temperature at the center of the pattern and the surroundings of each sample Whereas the maximum value of the temperature difference on the skin surface is 1.94 ° C. (Sample 4-2), when the back surface of the base of the sheet substrate is brought into contact with the human body, the maximum value of the temperature difference is 2. It has risen to 17 ° C. (Sample 8-1).

  This is because, when the back surface of the base of the sheet base material is brought into contact with the human body, the temperature difference between the charged particle generation layer containing the nanodiamond semiconductor particles and the human body surface is large at the beginning of the contact, and heat from the human body surface is Since it is transmitted to the charged particle generation layer through the base of the sheet base material and the pattern support layer, the temperature rise time of the charged particle generation layer is compared with the case where the charged particle generation layer of the sheet base material is in contact with the human body. Because the charged particle generation layer is continuously cooled by the atmosphere, the amount of heat generated by the thermoelectric effect (Seebeck effect) is higher than when the top surface of the particle generation layer is in contact with the surface of the human body. This is thought to be because it becomes larger.

  In Samples 2-1 to 2-3 and Samples 6-1 to 6-3 in which a lattice-shaped pattern is formed on a sheet base material, when the charged particle generation layer of the sheet base material is brought into contact with the human body, The maximum difference between the skin surface temperature at the center of the pattern and the skin surface around each sample exceeds 2 ° C when the back surface of the base of the sheet base material is in contact with the human body, and good results are obtained. It was.

On the other hand, there is no remarkable tendency regarding the width of the pattern of the charged particle generation layer formed on the sheet base material.
However, among the samples in which a stripe pattern is formed on the sheet base material, in Sample 1-1 (pattern width 0.3 mm) and Sample 1-2 (pattern width 0.5 mm), the charged particle generation layer of the sheet base material When the sample was brought into contact with the human body, no increase in the temperature of the surface of the human body was observed, whereas in Sample 1-3 where the pattern width was 1.0 mm, an increase in the temperature of the surface of the human body was observed. In consideration of changes in the pattern over time, the width of the pattern is preferably set to be larger than a predetermined value.
