Abstract

The invention consists of a diaper adapted to keep genitalia far from the body and exposed to the ambient temperature (to a certain degree), thereby allowing the genitalia to be cooled by ambient air and/or by PCM. It is postulated that this may have beneficial effects on the future sexual and gender development of infants and on the present reproductive health and function of adults in both sexes. This a new configuration is attended to prevent or to minimized human organism from fecal bacterial contamination.

Claims (14)

  1. 1. A diaper for both sexes consisting of: a. an inner section of material shaped to surround a person’s waist, having openings for the legs, provided with a front hole for the genitalia (penis and scrotum of a male, or vulva of a female) to project therethrough, said inner section having anterior and posterior portions; b. a pad on the inner side of said inner section adjacent to and just anterior to said front hole, adapted to prevent the leakage of urine and feces to genital area and said posterior section of said diaper and avoid contact of the urine with the skin. c. an outer section of material attached to said inner section optionally having a front hole for the scrotum or vulva to project through, said hole being covered by a thin air-permeable layer, whereby the scrotum or vulva is substantially exposed to free convection of ambient air and attend to prevented from contacting urine or feces.
  2. 2. The diaper of claim 1 wherein said inner anterior portion comprises hydrophobic materials adapted to repel moisture, and wherein said inner posterior portion of said inner section comprises internal hygroscopic materials adapted to absorb moisture and liquid from stool, and external hydrophobic materials adapted to prevent moisture and liquids urine diffusion from said outer section.
  3. 3. The diaper of claim 1 wherein said outer section of material comprises hygroscopic materials adapted to absorb fluids including urine and prevented their contact with skin.
  4. 4. The diaper of claim 1 wherein said inner and outer sections are composed of materials selected from the group consisting of: cotton, hemp, bamboo, microfiber, plastic fibers, such as polylactic acid or polyurethane, polyethylene or other, superabsorbent polymers, hygroscopic materials, and water repellent materials.
  5. 5. The diaper of claim 1 wherein the inner side of said innermost layer comprises either hygroscopic or water-repelling materials.
  6. 6. The diaper of claim 1 wherein the external side of said innermost layer comprises either hygroscopic or water-repelling material.
  7. 7. The diaper of claim 1 wherein said outer section comprises hygroscopic materials.
  8. 8. The diaper of claim 7, wherein said hygroscopic materials are disposed within a circle.
  9. 9. The diaper of claim 1 wherein said outer front section is further provided with a flap or pouch adapted to cover the scrotum/vulva.
  10. 10. The diaper of claim 1 further comprising phase-change material (PCM) stabilizing the temperature of said diaper.
  11. 11. The diaper of claim 1 wherein said innermost layer of inner back section is further provided with pockets on the interior back side, so located and adapted as to entrap and hold feces.
  12. 12. The diaper of claim 1 wherein said innermost layer of inner section is further provided with a raised area (between back and front sections), which prevents travel of feces from the posterior section of said diaper to the anterior section of said diaper.
  13. 13. A diaper having a substantially high-water absorbing capacity and substantially high gas and water permeability in areas of said diaper that are in proximity to a male scrotum or a female vulva.
  14. 14. The diaper of claim 1 adapted for increasing air convection near said genitalia, by allowing ambient air to circulate through said front hole.

Description

Smart Diaper for fertility and gender orientation Field of the Invention The present invention relates generally to the field of diapers, and more specifically application of new configured patented Smart Diaper for babies and adults. Background of the Invention The plastic (and usually waterproof) outer layers of a modem disposable diaper are impermeable and insulating with regards to heat and vapor exchange and are fitted tight to the body. These diapers therefore retain the body heat generated by the wearer, as well as the heat released by bodily fluids excreted. In addition to heat generated inside the diaper, bodily excretions induce inflammatory processes and infections due to fecal bacterial flora contamination through penetration into the genital tract in both sexes. This may have immediate negative effects on the health of babies and adults (including geriatric patients). In babies who have worn such diapers, effects upon the reproductive potential of the individual may occur after puberty, due to the damage from prolonged heating of the scrotum and acute or chronic inflammatory damages in the developing reproductive tissues (testicles, ovaries, oviduct and endometrium). In the natural situation, the scrotum temperature is certainly nearly 3-4 degrees lower than that of the body’s core, and this lower temperature is obligatory for normal sperm cell production after puberty, and possibly, for normal development (proliferation and differentiation) of fertility capacity (germ cells at different stages of development) at the period of neonates, infancy and toddlers. There is scientific evidence that suggests that increased temperature of the scrotum during neonate period and infancy may cause permanent damage to male fertility in adult age (Hadziselimovic and Herzog, The importance of both an early orchidopexy and germ cell maturation for fertility. Lancet 2001; 358:1156-1157). Possible results of this situation may include cryptorchidism and further reduced fertility due to the prolonged inner heat of testicles. In the female, it is speculated that heat exchange is also relevant for normal ovarian function (shown in bovine model; Morita et al., Establishment of long-term chronic recording technique of in vivo ovarian parenchymal temperature in Japanese Black cows. J. Reprod. Develop. 2020; 66:271-275). Another aspect of a novel configuration of diaper (Smart Diaper) is not only to protect reproductive potential and function of babies after puberty, but also to save normal development of baby’s brain. It is a well known phenomenon that the brain is develops all the time from birth (or rather from embryo period) until its maturation at puberty that leads to the beginning of start of fertility. The newborn brain weight is 0.35 kg, which is doubles to 0.7 kg (100%) at age of 6 months, then elevates to 1 kg (additional 30%) at age of 1 year old, then elevates to 1.2 kg (additional 20%) at age 2 years old and to 1.3 kg (additional 9%) at age 3 years old, without any additional weight elevation until puberty and adulthood. At this early stage of brain development, at the first year of life, the brain is veiy sensitive to hormonal influence in processes of sexual orientation. The brain develops as male brain in boys and female brain in girls under influence of the sex-hormonal surge at the first half of life year named mini puberty (Backer and Hesse, Mini puberty: why does it happen? Horm. Res. Paediatr. 2020; 93:76-84). This sex-hormonal surge starts immediately after delivery and disappears after the first 6 months of life until a new surge at puberty. In fact, the brain’s first sexual orientation (both for male and female) starts at embiyo stage, then the second one at first 6 months of life and the last one at puberty. It is postulated that humans have a critical period of early post-natal development during which over- or underexposure to sex hormones either masculinizes or feminizes the brain. The wearing of conventional diapers (elevated genital temperature) during this critical time for the development of the brain may have long term consequences for normal or abnormal hormonal secretion and sex-orientation of the brain. Summary of the Invention Normal modem diapers are generally made using air- and moisture-tight construction that prevents free passage of fluids between the body and the ambient. Such diapers are often worn nearly non-stop, during day and night, only being removed for diaper changes. It has been measured that such diapers maintain the infant genitalia at temperatures at least several degrees higher than those found in infants not using such diapers. We introduce a novel type of diaper, a “Smart Diaper” that facilitates more natural conditions for neonate and infant development. These improved conditions are postulated to be conducive to natural processes of development such as hormonal secretion, sex-orientation of developing brain and further reproductive health during this extre
