Description

[Technical Field]

[0001] This invention relates to a pad, and more particularly to a pad for use on the human body. [Background technology]

[0002] In addition to pregnancy, childbirth, and menopause, the congenital structure of the urinary tract is a contributing factor to urinary incontinence in women.

[0003] Women who experience urinary incontinence often use sanitary pads to prevent their underwear from getting wet.

[0004] For example, Patent Document 1 discloses an absorbent article comprising a surface sheet material, a back sheet material, and an absorbent body disposed between the surface sheet material and the back sheet material. The center area and side area of ​​the surface sheet material both have a grid-like pattern of recesses and protrusions. While this absorbent article can absorb leaked urine, the problem of urinary incontinence still causes inconvenience in daily life.

[0005] On the other hand, men frequently experience problems related to benign prostatic hyperplasia (BPH) due to age-related tissue proliferation.

[0006] Furthermore, modern people tend to develop hemorrhoids due to excessive sitting and constipation, which can lead to congestion of blood vessels around the anus, reduced venous return, and an increased risk of developing hemorrhoids.

[0007] Furthermore, patients who are bedridden for extended periods may develop bedsores due to pressure on the skin and poor blood circulation.

[0008] These symptoms can cause patients long-term suffering and negatively impact their daily lives.

[0009] These conditions are caused by poor blood circulation or muscle relaxation in the tissues surrounding the pelvic cavity, and alleviating the discomfort caused by these conditions is a problem that needs to be addressed. [Prior art documents]

Modes for Carrying Out the Invention

[0016] First, please understand that the reference of any prior art document in this specification does not imply, in Taiwan or any other country, that the content of such prior art document constitutes general knowledge in the art to which the present invention pertains.

[0017] Unless otherwise defined, all technical and scientific terms used herein have meanings that are generally understood by those skilled in the art. Those skilled in the art will recognize and utilize many methods and materials similar or equivalent to those described herein in the practice of this invention. Indeed, this invention is by no means limited to the methods and materials described herein.

[0018] The present invention relates to a pad for use on the human body, and includes a sheet body 1 as shown in Figures 1 to 3.

[0019] The pad of the present invention is mainly used around the pelvic cavity of the human body, or placed inside underwear pants, thereby allowing the sheet body 1 to be in close contact with the skin.

[0020] The sheet body 1 includes a first surface 101 and a second surface 102 which is the opposite side of the first surface 101, and has a plurality of fibers 11. That is, the first surface 101 and the second surface 102 are on opposite sides of each other.

[0021] In this embodiment, the sheet body 1 is a knitted fabric obtained by spinning and knitting a plurality of fibers 11.

[0022] In another embodiment, the sheet 1 may be a nonwoven fabric formed by directly bonding multiple fibers 11 under high pressure without spinning them. In the case of a nonwoven fabric, the multiple fibers 11 are arranged irregularly.

[0023] The shape, size, and thickness of the sheet 1 can be selected according to the part of the human body or the size of the wound used; therefore, the present invention does not limit the shape, size, and thickness of the sheet 1.

[0024] Each fiber 11 comprises a polymer substrate 111, a plurality of pyroelectric materials 112 distributed on the polymer substrate 111, and a plurality of coupling agents (not shown) distributed on the polymer substrate 111.

[0025] In this embodiment, the polymer substrate 111 is an aliphatic polyamide, and the aliphatic polyamide is polar nylon 6 (polycaprolactam).

[0026] In this embodiment, polymerized nylon 6 solid particles and powdered pyroelectric material 112 are uniformly mixed in a solid state, and then multiple fibers 11 are produced by melt spinning in a screw spinning machine 9.

[0027] Assuming the weight of each fiber 11 is 100 wt%, the content of the pyroelectric material 112 in each fiber 11 is in the range of 1 wt% to 3 wt%.

[0028] The pyroelectric material 112 in each fiber 11 contains kaolin, forsterite (whose main component is Mg2SiO4), and maifan stone.

[0029] In this embodiment, with the weight of each fiber 11 being 100 wt%, the content of the pyroelectric material 112 in each fiber 11 is 1.8 wt%, and the pyroelectric material 112 in each fiber 11 contains kaolin, forsterite, maifan stone, montmorillonite, and tourmaline, with the total weight of the pyroelectric material 112 in each fiber 11 being 100 wt%, the kaolin content is 50 wt%, the forsterite content is 20 wt%, the maifan stone content is 10 wt%, the montmorillonite content is 10 wt%, and the tourmaline content is 10 wt%.

[0030] Each pyroelectric material 112 may be a powder, a fine flake, or fine particles. The average surface width or average particle diameter of each pyroelectric material 112 is 1 μm.

[0031] In this embodiment, the polymer substrate 111 and the plurality of pyroelectric materials 112 are originally polar and are further polarized by the high-voltage field 91.

[0032] In this embodiment, the polymer substrate 111 and the plurality of pyroelectric materials 112 all have a pyroelectric effect, and therefore, when heated, a negative charge is released.

[0033] Multiple pyroelectric materials 112 exhibited a 1460 cm⁻¹ infrared spectrum. -1 , 1165cm -1 , 1090cm -1 , 968cm -1 and 720cm -1 It has an infrared absorption peak.

[0034] In this embodiment, the polymer substrate 111 is nylon 6 and belongs to the category of highly crystalline linear polymers, exhibiting an infrared spectrum of 720 cm⁻¹. -1 ~980cm -1 Since it has an infrared absorption peak within the range, nylon 6 has a CO-NH polar amide group in its molecular chain, and hydrogen bonds are formed between the molecular chains, giving it a dipole moment. When polarized by a high-voltage field 91, the intensity of the dipole moment can be increased.

[0035] In other embodiments, the polymer substrate 111 can be polyethylene terephthalate (PET) or polypropylene (PP).

[0036] Figure 4 shows the infrared spectrum of kaolin obtained by Fourier transform infrared spectroscopy (FTIR), Figure 5 shows the infrared spectrum of forsterite obtained by Fourier transform infrared spectroscopy, Figure 6 shows the infrared spectrum of maifanite obtained by Fourier transform infrared spectroscopy, Figure 7 shows the infrared spectrum of montmorillonite obtained by Fourier transform infrared spectroscopy, and Figure 8 shows the infrared spectrum of tourmaline obtained by Fourier transform infrared spectroscopy.

[0037] As shown in Figures 4 to 8, in the infrared spectrum, kaolin and maifanite are at 1460 cm⁻¹. -1 It has an infrared absorption peak of 1165 cm², and bakuhanseki is 1165 cm². -1 It has an infrared absorption peak of 1090 cm, and montmorillonite, maifanite, and tourmaline have the same peak. -1 It has an infrared absorption peak of 968 cm², and forsterite is 968 cm². -1 It has an infrared absorption peak of 720 cm, and the difference between maifan stone and tourmaline is 720 cm. -1 It has an infrared absorption peak.

[0038] The manufacturing process for the pad of the present invention will be described below.

[0039] First, the raw materials for the pyroelectric material 112 (i.e., a mixture of kaolin, forsterite, maifan stone, montmorillonite, and tourmaline) are crushed in a pulverizer to obtain several coarse powders with an average surface width of 5 μm. Then, they are magnetically separated using a magnetic separator at a magnetic flux density of 1.5 Tesla (T). The magnetically separated coarse powders are further finely crushed in a fine pulverizer to obtain several fine powders (i.e., pyroelectric material 112) with an average surface width or average particle diameter of 1 μm. Then, 1.2 × 10 8 The fine powder is polarized in a high-voltage field of V / m, then the polarized fine powder is washed with water, and finally dehydrated and dried.

[0040] That is, the multiple pyroelectric materials 112 distributed on the polymer substrate 111 are 1.2 × 10 8 It is polarized by a high-voltage field of V / m 91.

[0041] Then, the dried fine powder (i.e., pyroelectric material 112) and the polymerized nylon 6 particles (i.e., polymer base material 111) are uniformly mixed in a solid state while a coupling agent is added and mixed. Since the dried fine powder and the nylon 6 particles are mixed in a solid state, there is no influence from viscosity, and the uniformity of the mixing is improved.

[0042] Then, as shown in Figure 3, the mixed pyroelectric material 112 and polymer base material 111 are heated and melted in a screw spinning machine 9 and spun to produce multiple fibers 11, each containing multiple pyroelectric materials 112 and polymer base material 111.

[0043] As shown in Figure 3, 3.0 × 10⁻¹⁰ units are simultaneously produced during the spinning process. 6 V / m ~ 7.0 × 10 6 By polarizing the fibers with a high-voltage electric field 91 of V / m, the dipole moments of the multiple fibers 11 are regularly aligned parallel to the direction of the electric field, increasing the intensity of the dipole moments and obtaining a more pronounced hysteresis loop, thereby increasing the energy released from the charge. In this embodiment, the intensity of the high-voltage electric field 91 is 7.0 × 10⁻⁶. 6 It is V / m.

[0044] That is, multiple fibers 11 are melt-spun and 7.0 × 10 6 It is a mixture of a solid polymer substrate 111 and a solid pyroelectric material 112, which are polarized by a high-voltage electric field 91 of V / m.

[0045] Finally, after spinning multiple fibers 11 and weaving them into a cloth, a sheet body 1 can be cut from this cloth to create a pad that can be used directly on the human body.

[0046] In other embodiments, the sheet body 1 may be a nonwoven fabric containing a plurality of fibers 11, and at least one positioning member (not shown) may be placed on the first surface 101 of the sheet body 1, the positioning member being, for example, double-sided tape, which can improve the positioning effect when in use.
