  • This disclosure describes a garment, embodiment attached to the garment and/or sensor device that may manage, control, treat and/or provide early indication of vaginal health related infections but not limited to bacterial vaginosis and vaginal candidiasis.
  • An example embodiment may be comprised of a specialized construction that enhances breathability and improves air circulation/channelling/retention/permeability around a genital area to mitigate the growth of bad bacteria while maintaining the ideal microbiome or micro flora to promote the growth of good bacterial (such as Lactobacillus) and hence maintain an optimum vaginal pH level.
  • An example embodiment is designed for the purpose of absorbing bodily fluids, and retaining and trapping the bodily fluids within the top layer of the embodiment.
  • Bodily fluid can be vaginal discharges, secretions caused by different enzymatic reaction and thick/viscous fluids from vagina.
  • an example embodiment may be treated with probiotic treatment and/or anti odour finishes to promote vaginal health.
  • Probiotic treatment as disclosed herein may be comprised of any chemistry that can create a layer of good functional bacteria along with the prebiotics which are the nutrients for the probiotics and native good microorganisms.
  • strains of the bacillus family may include bacillus subtilis, bacillus pumilus and/or bacillus megaterium.
  • prebiotics may be selected to boost the bacillus strains. For example, increase of lactobacillus may be accomplished via competitive exclusion, which may include the process of ‘quorum sensing’.
  • control the growth of other bacteria may be accomplished by sending one or more signals, for example via the process of bacteria sensing the presence of other bacterial colonies and restricting development when another colony is dominant
  • Probiotic treatment may comprise any textile related finish that enhance the growth of good bacteria (Lactobacillus). This may contain specific strains/spores to address the optimum balance between good and bad bacteria by creating beneficial environment for the growth of good bacteria and hence maintain ideal vaginal pH.
  • the gusset panel probiotic treatment as disclosed herein may improve the growth of lactobacillus bacteria count. Different strains of bacteria may be used as probiotic treatment. Additionally, or alternatively, bacillus booster may be used as treatment, which is a prebiotic used to improve the lactobacillus.
