Description

TECHNICAL FIELD & BACKGROUND

The present invention generally related to toilet seat, and in particular, to an improved toilet seat.
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine. The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein.
Following filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibres that propel urine towards the urinary bladder, where it is stored and subsequently expelled from the body by urination. The female and male urinary system are very similar, differing only in the length of the urethra. Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the tubes made of smooth muscles around the bladder to the outside of the body.
Therefore, relaxing the muscles around the bladder will make it easier to empty the bladder. Similarly, during the motion of the digestive system to force waste matters out of the bowels into the rectum, the muscles of the rectum are induced to make a reactive contracting and the muscle of the anus is relaxed. Thus, relaxing the muscles of the anus will also make it easier to apply a pressure to the rectum to force waste matters out of the anus.
However, when the user sits on a regular toilet seat, the muscles of the bladder are in a contracted status, and the user is difficult to apply a pressure to the muscles of the bladder to squeeze urine out of the bladder. Because such regular toilet seat is kept in horizontal, the user would have difficulty applying a pressure to the muscles of the bladder.
A solution is to change the user's position in a half-squatting position such that the muscles of the bladder are relaxed, and the user can easily apply a pressure to the muscles of the bladder. Similarly, such half-squatting position also enables the user to easily apply a pressure to the rectum to force waster matter out of the anus by relaxing the muscles of the abdomen and the anus. However, the regular toilet seat cannot support such half-squatting position because the regular toilet seat is kept in horizontal. Thus, it would be desirable to provide an improved toilet seat that can support such half-squatting position to let the user easily apply a pressure to the muscles of the bladder to squeeze urine out of the bladder.
