Description

An Excrement Apparatus for Maintaining Personal Hygiene

FIELD OF THE INVENTION

[0001] The present invention relates to the area of excrement collection devices, such as bedpans. In particular, the present invention relates to excrement collection apparatus which allows the user to use water for cleaning their private parts after the process of excretion.

BACKGROUND OF THE INVENTION

[0002] Waste elimination is one of an essential fundamental function of the human body. Different groups of people in various regions of the world have devised different ways to clean oneself after performing the process of excretion. People from some areas of the world prefer using toilet paper while some groups of individuals prefer cleaning the private parts with water. People in many countries prefer to wash oneself thoroughly with water before performing any religious duties. From the health perspective, the use of soap and water are necessities in preventing infection

[0003] Individuals with limited mobility or the bed-ridden individuals typically employ the usage of the conventional bedpans to take care of the excretory requirements. However, the traditional bedpans have no way of providing water to these individuals to clean themselves. In the absence of water, these people have to resort to the usage of wet wipes or wet cotton balls. These are not the most economical alternatives. Also, long-term usage of these cleaning agents can cause infections. Further, the disease could worsen when a patient with limited mobility has developed bed sores. Bedsore wounds result when an individual lies on the pressure point of their sacral area for extended periods of time. The restricted movement ends in the insufficient blood supply to the sacral region. In many cases, the use of adult diapers had made patients with limited mobility to lie on their back for an extended period due to the function of its absorbent material. Furthermore, it takes a minimum of two individuals to help a patient with limited mobility to move in bed safely.

[0004] Bedpans have been developed in the art for the persons with limited mobility. For example, US5394571 discloses an inflatable bedpan assembly with an inflatable horseshoe-shaped seat and a detachable waste collection bag which is sealed with a drawstring. The bedpan is almost flat in a deflated condition and has a shape of a thick toilet seat when inflated. A waste accumulating bag substitutes for the bowl in a regular toilet. The bag is inserted before use, then is pulled out through a gap in the front of the seat. The bag closes and seals when it is pulled out. The collection bag is attached to the bedpan using a sleeve which is around the opening of the pocket and contains a drawstring. The sleeve including the drawstring is wedged into a groove or channel formed around an inner circumference of the seat directly below the top surface. After use, the drawstring and sleeve, with the suspended collection bag, are drawn out of the groove in the horseshoe and removed by the front gap.

[0005] EP0207730A1 discloses an inflatable receptacle for use as a bidet, lavatory, or for other toilet purposes comprises an inflatable wall surrounding a base, and a seat portion around the upper peripheral edge of the wall. US6000078A discloses a disposable bedpan for use with a patient underlayment that has a cavity in registry with buttocks of a supine patient lying thereon, wherein the bedpan is supported in the cavity by a laterally-collapsible hoop-like support. The hoop-like support has fulcrum extensions to give support for a horizontal support upon which the underlayment rest and markings on the removable bedpan present a tool to measure the quantity of waste from the patient. A padded plug that fills the area between the hoop-like support and top of underlayment provides relief for the patient while the bedpan is installed but not in use.

[0006] However, a few disadvantages associated with the aforementioned prior art documents is that none of the systems described in the prior art disclose a means or a method which allows the individuals with limited mobility to clean themselves with water after the process of excretion, as is the custom in many of the Asian countries.
