ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device can be to be used for conducting away urine and excreta by a person relieving him or herself, said device assembled from a sheets of web material to form funnel shaped hose structure having cop and bottom portions with inlet and discharge openings thereat, respectively.
The present invention was devised to serve persons who for whichever reason wish to urinate while standing up or to empty a device such as a stomal collection bag (stoma bag) as discrietly as possible. Due to the free fall height and the dispersion angle, which is difficult to control, the substance to be evacuated often sprays and splashes about in the form of droplets that end up outside the toilet bowl or on the user's clothes.
2. Background Art
DE 43 43 789 C2 discloses a urine discharge device comprising a flexible hose member having openings at both ends and made of a material which dissolves in water at least partly and with some delay. This urine discharge device in hose form has a funnel shaped inlet, manual holding means at the top as well as a discharge opening in its bottom portion.
DE 44 43 182 C2 discloses a device for accepting and discharging urine from a person particularly a human male relieving himself. This prior device comprises a flexible hose element made of a sheet of a web material such as paper folded to form two superimposed layers and having a manual holding portion, an inlet portion and a discharge portion. A multitude of said layers are integrally connected together in a longitudinal channel at their common front edge in a quasi endless succession,
U.S. Pat. 4,608,046 discloses a device for evacuating urine from women which comprises a tube to be introduced in the labia. This tube is flexible in order to con form to the individual user's physical features.
All these above described prior devices present a major problem when the inlet is to be opened. With the device collapsed and flat, the device is space saving and inexpensive to transport and simple to store; in contrast, spreading it to open the inlet is complicated as the user usually has only one free hand to accomplish the task.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a device for reducing the fall height of and conducting body excreta of which the inlet opening is easy to open.
This object is achieved by a coat of an adhesive substance applied to the surface of the web material in the general region of the inlet opening
The aforesaid adhesive substance is provided in the top area adjacent the inlet opening. It extends horizontally and circumferentially in an adhesion area on the surface, whereby the user can rub his or her thumb and index finger against each other to exert on the folded together or collapsed device a force sufficient to form an opening in the inlet area.
Beings and particularly humans whose ureter or lower intestine is made by surgery to open at an unnatural location on the body surface often experience major problems when they attempt to dispose their excreta in a controlled and discrete manner. These individuals have had sections of their lower intestine removed by surgery to remove an intestinal cancer. In the process, the intestinal or urethral orifice is artificially relocated on the abdomen and provided with a discharge valve to which a catheter may be connected when needed. This arrangement greatly impedes a dosed discharge of the excreta.
The problem can be solved by means of a device consisting of a sheet material which dissolves in water at least partly and with some delay, the device forming a flexible hose with a top portion having an inlet therein and a bottom portion having a discharge opening therein and being used for conducting excrera away from a being's artificial intestinal or urethral orifice.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
