Definitions

  • the present subject matter relates to a toilet arrangement for supporting a user in a squatting position.
  • a typical toilet arrangement includes a toilet bowl with an oval seat section.
  • a user may be supported by placing buttocks on a periphery of the oval seat section and foots on ground, and thereby perform defecation.
  • the upright sitting posture of the user is similar to a sitting posture, when the user sits on a chair.
  • Such toilet arrangements promises good sanitary conditions, however, such toilet arrangements fail to facilitate easy and complete defecation. Particularly, as shown in FIG.
  • an indigenous toilet arrangement may be used with a foot rest provided on top of the toilet arrangement.
  • indigenous toilet arrangement the user is supported by placing the feet on the foot rests, to provide substantial natural squatting position for defecation.
  • the anal canal [206] of the user is vertically aligned with the rectum [204] of the user, due to relaxation of the puborectalis muscle [202]
  • indigenous toilet arrangements may fail to provide good sanitation conditions.
  • the feet of the user are only supported (which has to bear the total body weight), causing a discomfort to the user.
  • European patent EP0413063A1 discloses a toilet bowl with an upper rim and footrest means for supporting a user above ground level.
  • the disclosed toilet bowl is structured, such that the upper rim and the foot rest means combine in use of the toilet bowl, to enable persons to sit on the toilet bowl and be supported in a natural squatting position.
  • this patent discloses support of the person in natural squatting position.
  • the positon is still not completely full squat, as the appropriate angular inclination of the torso of the person relative to thighs is not focused in this article.

  • this document discloses the appropriate angular positioning of the footrest areas, and the bend of torso relative to the thighs of the user, however, the user is supported on a flat seat means causing a pointed normal force on one portion of the buttocks of the user. This causes a relatively larger pointed normal pressure on certain muscles (particularly muscles surrounding the anal canal [206]), thereby constricting the anal canal [206] and resulting in difficulty in defecation. Therefore, the whole purpose of the defecation is lost, due to constriction of the anal canal [206] of the user.
  • An object of the present subject matter is to provide a toilet arrangement that supports a user in a natural squatting position for enabling complete defecation.
  • Another object of the present subject matter is to support the user with torso bent at 22.5 degrees relative to the thighs, feet inclined at an angle of 30 degrees and positioned 3.5 inches below the buttocks, and the buttocks being supported to experience push away force (angled force causing expansion of the buttocks).

Abstract

L'invention concerne une installation de toilettes [100] permettant de supporter un utilisateur en position accroupie. L'agencement de toilettes [100] comprend une cuvette de toilettes [102] ayant une partie de siège arrière [114], deux repose-pieds [104] de chaque côté de la cuvette de toilettes [102], et un support lombaire [106], pour supporter un utilisateur en position accroupie naturelle. Dans la position accroupie naturelle, le support lombaire courbe la région lombaire à 22,5 degrés par rapport aux cuisses de l'utilisateur, les repose-pieds [104] supportent le pied pour permettre une flexion de hanche de 45 degrés, et la partie de siège arrière [114] supporte les fesses pour fournir une force de poussée sur les fesses de l'utilisateur. Avec une telle installation, le canal anal [206] est aligné tout à fait verticalement avec le rectum [204] de l'utilisateur.
