Definitions

  • This invention relates generally to a method and equipment for reducing the physical damage to a person when that person is using a toilet to make a bowel movement, and, more specifically, to a foot support or elevation system which places the human body into an improved physiological position when the person is using a toilet to make bowel movement.
  • Many people experience constipation. When that happens, they frequently find themselves trying to force bowel movements in a process called "straining at stools”. This process of forcing the bowel movement, when the person is in a normal sitting toilet position, is often very damaging to the person's internal organs, muscles, cartiledge, and ligaments. In particular, it has been associated with damage to the colon and rectal area.
  • the toilet is designed with foot platforms or positions on each side of the toilet and at the level of the toilet seat, so that the user can actually support their entire body weight on these foot platforms and assume a true squatting position over the toilet. This is essentially achieved without any necessity for non-foot contact with the toilet itself.
  • this approach appears to allow an improved physiological position, it does create a very unstable position for the user and very significantly increases the risk of accidental falling and attendant injury.
  • a second category involves providing a non-unitary device which sits in front of the toilet or around the front of the toilet and which provides a surface upon which the user's feet can be elevated into the appropriate position.
  • One group of designs which adopt this approach are simply specially-shaped stools which either sit in front of the toilet or wrap around the front of the toilet. Because the floor of most bathrooms is fairly slippery, these free standing stool-type structures can be quite unstable and can slip forward and away from the toilet leaving the user in a very unstable position or causing undue stress.
  • Another approach involves including a super structure of elements that extend upward from the free standing stool and which allow the user to hold the stool in place and possibly rest the upper body on the super structure.
  • a further object of the present invention is the provision of a foot elevator for use by a sitting toilet user which device is stable and will not slide away from the toilet when the user is using the device to elevate the user's feet. This is accomplished by non-skid devices on the bottoms of the feet of all of the legs. In addition, the feet of the device are shaped so that movement is even more difficult and so that the effectiveness of the non-skid devices on the bottom is greatly increased..
  • a still further object of the present invention is the provision of a foot elevator for use by a person sitting on the toilet, which can be easily connected or disconnected to the toilet so that the device can not be removed by children and yet can be easily removed for cleaning or other purposes.
  • the foot elevator system be height adjustable by means of adjustable legs which makes the system ergonomically and physiologically correct .
  • This invention is a stool designed to sit in front of and wrap slightly around the front base of a toilet to elevate the feet of a sitting toilet user about nine inches (six to twelve inches, depending on the height of the user) above the normal position of the foot to decrease the angle between the user's upper legs and the user's torso and thereby to allow more effective use of the toilet for bowel movements.
  • the device may have adjustable legs to allow users of varying heights to raise their legs to the correct level to achieve a more appropriate in ara-angle for the bowel.
  • the device may have a system for keeping the device from moving away from the toilet and, more specifically, the device may have strap which passes around the back of the toilet to keep the device from moving away from the toilet when the user has the user's feet on the device.
  • the strap makes it more difficult for a small child to move the stool from the toilet to another location where the stool might allow undesired access for the child.
  • the bottoms of the legs of the system may have friction enhancing floor contact surfaces that discourage system from unintentionally sliding along the floor.
  • the device is ergonomically shaped to allow for the most comfortable, defecation-enhancing position of the feet.

DETAILED DESCRIPTION OF THE INVENTION [0043] As best shown in FIG. 1, the foot elevation system, generally indicated by the reference numeral 10, is shown positioned in front of and attached to a toilet and bearing and elevating the feet of a user sitting on the toilet.
  • FIG. 2 the foot elevation system is shown attached to the toilet.
  • the nons d surface 12 on the top surface 11 of the system is shown and allows the user to place the user's feet in the most comfortable position.
  • FIG. 3 shows a top view of the system with the toilet sectioned so that the preferred manner of attaching the system to the base of the toilet is shown.
  • a strap 13 extends from each side of the system and extends around the back with the base of the toilet to lock the device into position at the front base of the toilet. The strap can be unfastened so that the device can be easily removed from the toilet if desired.
  • the length of the strap can be adjustable and it can be elastic so that it will universally adapt to the various geometries of toilet and still provide a stable connection between the system and the toilet.
  • FIG. 4 shows, in a schematic view, the anal region of a person sitting on a toilet in the normal sitting position. This illustration shows the sacrum sa, the coccyx bone cb, the purburectal muscle pm, the rectum re, and the anus an.
  • ara-angle alpha It has been observed by radiological examination during the movement of the bowels that the anorectal-angle, well known in the special language as ara-angle and hereinafter referred to as ara-angle alpha ( ) is extremely important.
  • ara-angle alpha it may be determined that the anus-channel ac is in a straight line with the rectum re and, therefore, reduces resistance to the movement of the bowels, or, if the anus-channel ac is bent out of line with the rectum re, resistance to material flow occurs, and complicates the movement of the bowels.
  • this ara-angle alpha is measured between the tangential elongation, between the beginning of the anus an and the back partition of the rectalampulera and the central axis ca of the anus an. In the normal sitting posture, the size of the ara-angle alpha is about 90 degrees. During defecation, this ara-angle alpha increases to 110 degrees due to the relaxing of the anus-muscle or puborectal muscle pm.
  • An ara-angle alpha of 90 degrees in the sitting posture and of 110 degrees during the defecation indicates that the anus-channel ac is out of line and bent against the rectum re and, therefore, creates a mechanical obstacle which restricts the movement of the bowels during defecation. Therefore, it may be understood that the posture on common toilets is not optimal for defecation.
  • a straightening of the anus-channel may be achieved by adopting a squatting posture during defecation. This natural posture is still found in use in less developed countries. However, in most of the industrialized countries, a sitting posture is preferred, which generally allows a more dignified, albeit not necessarily more healthy, execution of the defecation.
  • FIG. 5 shows a diagrammatic view of the anus region of a person in a squatting posture.
  • the anus-channel ac is more or less in a straight line with the rectum re.
  • the value of the ara-angle alpha is approximately 118 degrees.
  • This ara-angle alpha increases to approximately 135 degrees during defecation. Therefore, if the ara-angle alpha reaches approximately 120 degrees, an optimal posture for defecation is reached, because of the approximate alignment of the anus channel ac with the rectum re.
  • an ara-angle alpha of 120 degrees will be reached if the angle between the thighs and the torso is approximately 30 degrees. This angle is measured between the femur and a straight line which leads from the sacral segment si to the back of the neck.
  • FIG. 6 shows the top view of the system of the present invention.
  • a planar top surface consists completely of a large slip resistant area appropriate for placing the person's feet on the top surface of the device in the position most comfortable for the user.
  • a strap is provided on the back of the device to fix the device to the toilet and fastening elements are included on each side of the device for holding the strap to the device.
  • An inset portion on the back of the device allows the device to surround the front and some of each of the sides of the toilet base.
  • the drawings show a design with seven legs; one on each of the four rear comers, two spaced-apart and centered on the front edge, and one on the rear edge of the forward portion, adjacent the toilet base.
  • An alternative design replaces the two front legs with a single leg centered on the front edge.
  • FIG. 7 shows a bottom view of the device including seven legs, one at each rear comer, two on the front edge and one on the rear edge of the forward portion.
  • FIG. 8 shows a front view of the device including the fastening elements on each end and the front two legs. It should be understood that the two front legs could be combined into a single front centered leg.
  • FIG. 9 shows a rear view of the device including the strap, the fastening devices on each side, the two rear legs 15, and the inset portion which allows the device to surround the front and sides of the toilet base.
