[0002] Women are prone to urinary incontinence due to pregnancy, childbirth, menopause, and the inherent structure of their urinary tract. Men, on the other hand, often experience prostate enlargement as they age due to tissue hyperplasia. Furthermore, prolonged sitting and constipation often cause congestion in the blood vessels near the anus, reducing venous return and making hemorrhoids more likely to develop. Pressure on the skin and poor circulation in bedridden patients can lead to pressure ulcers. These conditions can be lingering and can even affect daily life.

[0025] See Figures 1 to 3 The embodiment of the protective pad for human body of the present invention comprises a sheet 1. The present invention is mainly used around the pelvic cavity of the human body, or used as a pad in underwear, whereby the sheet 1 can be directly adhered to the skin.

[0026] The sheet 1 comprises a plurality of fibers 11 and includes a first surface 101 and a second surface 102 opposite the first surface 101. In this embodiment, the sheet 1 is a woven fabric formed by spinning and weaving the fibers 11. However, in other variations, the sheet 1 may be a non-woven fabric formed by directly bonding the fibers 11 together using high pressure, without spinning. In this case, the fibers 11 are arranged in an irregular pattern. Since the shape, size, and thickness of the sheet 1 can be selected based on the intended human body part or wound size, the shape, size, and thickness of the sheet 1 are not limitations of the present invention.

[0027] Each fiber 11 comprises a polymer matrix 111, a plurality of pyroelectric materials 112 distributed within the matrix 111, and a plurality of coupling agents (not shown) distributed within the matrix 111. In this embodiment, the polymer matrix 111 is an aliphatic polyamide, which is polar nylon 6. In this embodiment, solid pellets of polymerized nylon 6 and finely powdered pyroelectric materials 112 are first mixed uniformly in a solid state, and then melt-spun using a screw spinning machine 9 to form the fibers 11.

[0028] The content of the pyroelectric material 112 in each fiber 11 is 1 wt% to 3 wt%, and the pyroelectric material 112 contains kaolin, forsterite (primarily composed of Mg2SiO4), and medical stone. In this embodiment, the total weight of each fiber 11 is 100 wt%, and the content of the pyroelectric material 112 is 1.8 wt%. Each pyroelectric material 112 contains kaolin, forsterite, medical stone, montmorillonite, and tourmaline. The total weight of each pyroelectric material 112 is 100 wt%, and the weight percentage of kaolin, forsterite, medical stone, montmorillonite, and tourmaline is 50 wt%, 20 wt%, 10 wt%, 10 wt%, and 10 wt% of tourmaline. The pyroelectric material 112 can be in the form of powder, flakes, or granules, and has an average surface width or average particle size of 1 μm.

[0029] The pyroelectric material 112 and the polymer substrate 111 of this embodiment are both polar and polarized by the high voltage electric field 91. Since the polymer substrate 111 and the pyroelectric material 112 of this embodiment have pyroelectric properties, they release negative charges when heated. In the infrared absorption spectrum measurement, the pyroelectric material 112 has a negative charge at 1460 cm -1 、1165cm -1 , 1090cm -1 、968cm -1 and 720cm -1 The polymer substrate 111 of this embodiment is nylon 6 and has an absorption at 720 cm in the infrared absorption spectrum measurement. -1 Up to 980cm -1 The polymer substrate 111 has absorption, and its molecular chain has polar amide groups of CO-NH, belonging to a highly crystalline linear polymer structure. Hydrogen bonds are formed between the molecular chains, and the polymer substrate 111 has a dipole moment, which can be enhanced by polarization with a high-voltage electric field. However, in other variations, the polymer substrate 111 can also be made of polyester fiber (PET) or polypropylene fiber (PP).

[0030] See Figures 4 to 8 In the infrared absorption spectrum, kaolin and medical stone have the highest -1 Medical stone absorbs at 1165cm -1 There is absorption at 1090cm. Montmorillonite, medical stone and tourmaline absorb at 1090cm -1 There is absorption at 968cm. -1 Medical stone and tourmaline absorb at 720cm -1 There is absorption everywhere.

[0031] The manufacturing process of the protective pad for human body of the present invention is described below:

[0032] First, the raw materials of the pyroelectric material (i.e., a mixture of kaolin, forsterite, medical stone, montmorillonite, and tourmaline) are pulverized in a pulverizer to obtain a plurality of coarse powders with an average surface width of 5 μm. Then, a magnetic separator is used to perform magnetic separation at a magnetic flux density of 1.5 Tesla (T). The coarse powder after magnetic separation is then finely ground in a grinder to obtain a plurality of fine powders with an average surface width or particle size of 1 μm. Then, a 1.2×10 8 The fine powder is polarized by a high voltage electric field of 800 V / m, and the polarized fine powder is added with water and washed and purified, and finally dehydrated and dried.

[0033] Next, the dried fine powder is added to the polymerized nylon 6 pellets, and the two are mixed evenly in a solid state. A coupling agent is then added and kneaded together to form a mixture. Since the fine powder and nylon 6 pellets are mixed in a solid state, there is no viscosity effect, which increases the uniformity of the mixture.

[0034] Then, the mixture is put into the screw spinning machine 9 for heating, melting and spinning to obtain the fiber 11. During the spinning process, 3.0-7.0×10 6 The high voltage electric field 91 of 7.0×10 / m is polarized to make the dipole moment of the fiber 11 regularly arranged parallel to the direction of the electric field, thereby increasing the strength of the dipole moment and obtaining a more obvious hysteresis curve, thereby increasing the energy of the released charge. 6 V / m.

[0035] Finally, the fibers 11 are spun and woven, and then cut into the sheet 1 for immediate use. In some variations, the sheet 1 may be made of non-woven fabric, or at least one positioning member (not shown), such as double-sided tape, may be provided on the first surface 101 of the sheet 1 to enhance positioning during use.
