This invention relates to urinary funnels, and more particularly to a urinary funnel with a biological test indicator.
Urinary funnels for allowing women to urinate in a standing position are known in the art, and generally provide for a convenient and clean method for women to urinate without contacting toilet seats that may be unsanitary, particularly in public restrooms.
Biological indicator tests, such as drug or pregnancy tests, typically include an indicator strip that is to be placed within the urine stream to activate the biological indicator. Such devices, for both men and women, often require the strip to be held so close to the urine stream that some urine inevitably splashes onto the user's hands, which is unsanitary and may result in the user not adequately soaking the test strip with the urine.
U.S. Pat. No. 5,605,161 to Cross on Feb. 25, 1997 teaches a urinary funnel that includes a detachable urinalysis reagent strip. While such a device does provide a funnel structure for allowing a person to urinate in a standing position, the detachable urinalysis ring, once soaked in urine, is not easily handled without contacting the urine. Further, such a device, while collapsible in an axial direction with an accordion-type pleated arrangement, does not collapse down to a size suitable for carrying in a standard folded wallet.
Therefore, there is a need for a funnel device that allows both men and women to urinate in a standing position and to expose a urinalysis test or test strip to the urine stream produced thereby. Such a needed device would be collapsible to an extent readily transportable in a standard folded wallet, and would provide a means by which the test strip is detachable from the disposable funnel device and may be cleanly handled and transported. Such a needed device would be relatively inexpensive to manufacture and intuitive to use. The present invention accomplishes these objectives.
The present device is a urinary funnel comprising a collapsible funnel structure having a proximal opening and a distal opening. The funnel structure has an inner surface and an outer surface, and is made from preferably a resilient web scored to define two side panels foldable at a lower fold line that attach mutually together at a top flap. The funnel is collapsible so as to be carried in a wallet or purse.
At least one biological indicator is fixed with the inner surface of the funnel structure proximate the distal opening. A legend or indicia may be printed on the outer surface of the funnel structure to indicate how to read the results of the biological indicator after exposure to the urine. An aperture through the funnel structure may be included through which the at least one biological invocator may be viewed. A transparent material may cover the aperture to prevent fluid from spilling through the aperture.
In use, when urine flows between the proximal opening to the distal opening, the at least one biological indicator is activated by the urine to indicate a biological condition. For example, the biological indicator may be a visual indicator for detecting the use of illicit or prescription drugs by the user as evidenced by the presence of drug-related metabolites in the urine, such drugs being, for example, cannabis, alcohol, nicotine, cocaine, opiates, or the like. In one preferred embodiment the biological indicator detects the presence of pregnancy-indicating hormones in the urine.
In one embodiment, the web further includes a transverse slot proximate the lower fold line that is adapted to receive a biological indicator test strip therethrough. The biological indicator is applied to the biological indicator test strip that is in turn positioned through the transverse slot to rest against the inner surface of the funnel structure within the stream of urine flowing from the proximal opening to the distal opening. In such an embodiment, a liquid-absorbing material covers the transverse slot and a portion of the inner surface of the web, thereby defining a test strip pocket adapted to receive the biological indicator test strip therein.
In one embodiment the biological indicator test strip is partially enclosed in a test strip cartridge with an exposed portion of the test strip projecting away therefrom and adapted to be inserted into the transverse slot. In such an embodiment the outside surface of the funnel structure further includes a test strip cartridge attachment mechanism for selectively and temporarily securing the test strip cartridge to the funnel structure. A cartridge cap may be included and adapted for covering the exposed portion of the test strip when the test strip cartridge is removed from the funnel structure.
The present invention is a funnel device that allows both men and women to urinate in a standing position and to expose a urinalysis test or test strip to the urine stream produced thereby. The present device is collapsible so as to be readily carried in a standard folded wallet, and provides a means by which the test strip is detachable from the disposable funnel device and may be cleanly handled and transported. The present invention is relatively inexpensive to manufacture and intuitive to use. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word “each” is used to refer to an element that was previously introduced as being at least one in number, the word “each” does not necessarily imply a plurality of the elements, but can also mean a singular element.
Preferably the funnel structure 11 comprises a resilient web 20 (
In one embodiment the resilient web 20 further includes a proximal flap 100 (
Preferably the resilient web 20 further includes a pair of score lines 130 (
At least one biological indicator 90 is fixed with the inner surface 21 of the funnel structure 11 proximate the distal opening 80. The hydrophobic coating 200 is not included in the area of the biological indicator so that the urine 15 may fully contact the at least one biological indicator 90. In one embodiment the at least one biological indicator 90 is positioned on the funnel structure 11 so as to be visible through the distal opening 80 (
In use, when urine 15 flows between the proximal opening 70 to the distal opening 80, the at least one biological indicator 90 is activated by the urine 15 to indicate a biological condition. For example, the biological indicator 90 may be a visual indicator for detecting the use of illicit or prescription drugs by the user as evidenced by the presence of drug-related metabolites in the urine 15, such drugs being, for example, cannabis, alcohol, nicotine, cocaine, opiates, or the like. In one preferred embodiment the biological indicator 90 detects the presence of pregnancy-indicating hormones in the urine 15.
In one embodiment the resilient web 20 further includes a test strip 170 extending past the distal opening 80 (
In one embodiment, the web 20 further includes a transverse slot 210 proximate the lower fold line 40 that is adapted to receive a biological indicator test strip 220 therethrough. The biological indicator 90 is applied to the biological indicator test strip 220 that is in turn positioned through the transverse slot 210 to rest against the inner surface 21 of the funnel structure 11 within the stream of urine 15 flowing from the proximal opening 70 to the distal opening 80. As such, a non-exposed portion of the test strip 220 may be pulled to remove the test strip 220 from the funnel structure 11 after urinating, with the funnel structure 11 thereafter being disposed of.
In such an embodiment, a liquid-absorbing material 230 (
In one embodiment the biological indicator test strip 220 is partially enclosed in a test strip cartridge 270 (
