Embodiments of the present invention relate to systems for collecting urine specimens and methods of using such systems.
Urine analysis is required in a variety of situations and settings, such as during doctor's visits or as a term of employment (e.g., random drug testing). Regardless of the reason or the setting, providing a urine sample can be a messy process, particularly for women. For woman, providing a urine sample typically requires the user to suspend a specimen cup within the toilet at the location they believe the urine flow will be directed. Rarely is that location accurate. Rather, more often than not women end up urinating on their hand(s) as they scramble to adjust the location of the cup.
Specimen cup holders have been developed that effectively remove the hand from the situation. More specifically, the holders include a handle and a cup holder provided on a distal end of the handle. An aperture is provided within the cup holder for receiving a specimen cup. In use, the cup is positioned within the aperture and the user suspends the cup within the toilet using the handle. However, such prior holders have overwhelmingly been made of a non-absorbent material, such as plastic. Thus, if urine impacts the holder, it drips from the holder. Moreover, the design of these prior holders does not render them suitable for widespread dispensing and use in a restroom setting. More specifically, the geometry of prior holders makes it difficult (if not impossible) to provide multiple holders in a compact fashion. Overall, there is a need for an improved urine collection system that results in a more sanitary urine collection process.
The terms “invention,” “the invention,” “this invention” and “the present invention” used in this patent are intended to refer broadly to all of the subject matter of this patent and the patent claims below. Statements containing these terms should be understood not to limit the subject matter described herein or to limit the meaning or scope of the patent claims below. Embodiments of the invention covered by this patent are defined by the claims below, not this summary. This summary is a high-level overview of various aspects of the invention and introduces some of the concepts that are further described in the Detailed Description section below. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used in isolation to determine the scope of the claimed subject matter. The subject matter should be understood by reference to appropriate portions of the entire specification of this patent, any or all drawings and each claim.
Some embodiments are directed to a cup support having a top and a bottom. The cup support also includes a head portion defining an aperture having an aperture opening adapted to receive a specimen cup for the collection of a liquid, the aperture opening including a continuously curved, circular profile and a diameter configured to receive the specimen cup in a direction from the top to the bottom of the cup support. The cup support also includes a handle portion extending from the head portion. The head portion and the handle portion can be integrally formed, and the cup support is adapted to absorb liquid that impinges on it during use.
Other embodiments include a cup support having a top and a bottom and a head portion that includes a base wall having an outer perimeter and an inner wall that extends upwardly from the base wall in a direction away from the bottom of the cup support. The inner wall at least partially defines, and extends at least partially around, an aperture including an aperture opening adapted to receive a specimen cup for the collection of a liquid, the aperture opening including a continuously curved, circular profile and a diameter configured to receive the specimen cup in a direction from the top to the bottom of the cup support. The cup support also includes a handle portion extending from the head portion and including a base wall having an outer perimeter. An outer wall extends upwardly from, and around at least a portion of the outer perimeter of, at least one of the base wall of the head portion or the base wall of the handle portion in a direction away from the bottom of the cup support. In some embodiments, the head portion and the handle portion are integrally formed from a liquid absorbent material. A trough having a base may be defined between the outer wall and the inner wall on the head portion such that the base of the trough is located more proximate the bottom of the cup support than the aperture opening.
Other embodiments are directed to a stack of nested cup supports. Each cup support includes a head in which is defined an aperture having a diameter configured to receive, in a direction from the top to the bottom of the cup support, a specimen cup for the collection of a liquid, where the head includes an outer wall that extends around at least a portion of a perimeter of the head and upwardly in a direction away from the bottom of the cup support. The cup supports also include a handle extending from, and integrally formed with, the head. When nested, the head of an upper cup support in the stack of cup supports is at least partially received within the outer wall of the head of a cup support located immediately below the upper cup support in the stack of cup supports.
Illustrative embodiments of the present invention are described in detail below with reference to the following photographs:
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
Embodiments of the present invention include a specimen collection system that includes a cup support having a handle and head extending from one end of the handle. An aperture is provided within the head for receiving a specimen cup. In use, the specimen cup is positioned within the aperture so as to be supported by the head of the cup support, and the user suspends the cup within the toilet using the handle. In this way, the user's hand is remote from the situation and thus less likely to get soiled during use. Note that while this disclosure describes the invention with respect to urine collection, it is not so limited. Rather, it may be applied to other circumstances where collection of a liquid is desired. Moreover, it should be noted that the users of the cup supports disclosed herein may be the person providing the sample, but may also be a third party overseeing the urine sample collection process.
In some embodiments, all of the features of the cup support disclosed herein are formed integrally of a single material. It is preferable, but not required, that the cup support be formed from recycled and/or renewable materials. In some embodiments, the cup support is formed from one or more biodegradable materials. The cup support can be formed of any material, such as, but not limited to, cellulose materials, polymeric materials, ceramics, metallic materials (e.g., stainless steel, etc.), and silicon/silicone materials. While embodiments of the cup support may be designed for multiple uses (e.g., used once and sterilized for subsequent use), in some embodiments the cup support is formed of a material designed for a single use, such as cellulose (e.g., pulp/paper) or thin plastic. In some embodiments, the cup support is adapted to absorb liquid that impinges upon the cup support. For example, in some embodiments the cup support is formed of a material that is naturally absorbent to liquids or that has been adapted to be absorbent to liquids, such as cellulose fibers and more specifically pulp fibers. This is in contrast to prior designs which have primarily been formed of naturally non-absorbent materials or materials that have been rendered non-absorbent (e.g., coated with a water/liquid resistant material). If urine impacts such non-absorbent holders, it is apt to drip from the cup support.
In other embodiments, the handle and the head may be formed separately (of the same or different materials) and subsequently attached or connected to each other for use. For example, the handle could be formed of a material that permits its reuse, while the head could be formed of a material designed for single use.
The cup support can be formed via any of a variety of methods, including, but not limited to, compression molding, transfer molding, injection molding, thermo-forming, vacuum-forming, etc.
Any diameter of aperture 18 may be provided, but the diameter of the aperture 18 is preferably selected such that a variety of different-sized specimen cups may be dropped into and retained within the aperture 18 without falling through the aperture 18. For example, larger diameter cups would simply not extend as far within the aperture 18 as smaller-diameter cups. In this way, the cup support 10 can be used universally with a variety of different specimen cups. Aperture diameters of between one and six inches, inclusive; between one and five inches, inclusive; between one and four inches, inclusive; between one and three inches inclusive; between one and two inches inclusive; between two and five inches inclusive; between two and four inches, inclusive; between two and three inches, inclusive; between three and six inches, inclusive; between three and five inches, inclusive; and between three and four inches, inclusive will typically be suitable for most specimen cups.
In some embodiments, the base wall 16 is planar and/or extends radially outwardly from the aperture so as to extend co-planar with the aperture 18 (i.e., approximately 90° relative to the aperture axis y). However, in other embodiments, the base wall 16 can angle upwardly or downwardly from the aperture 18, such as at a non-zero angle that is greater than 0° but less than 90° when measured upwardly or downwardly from the aperture axis y (e.g., extending at an angle equal to or greater than 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85° but less than 90° when measured upwardly or downwardly from the aperture axis y).
The handle portion 12 can be of any length L but is preferably of a length that sufficiently distances the hand of the user from the urine stream during use. In some embodiments, the handle portion 14 has a length L between one and ten inches, inclusive; between one and eight inches, inclusive; between one and six inches, inclusive; between two and five inches, inclusive; between two and four inches, inclusive; between one and four inches, inclusive; between one and three inches, inclusive; between two and three inches, inclusive; between three and six inches, inclusive; or between three and five inches, inclusive. In some embodiments, the handle length L will be at least 1 inch, at least 1.5 inches, at least 2 inches, at least 3 inches, or at least 4 inches, but less than 10 inches, less than 8 inches, less than 7 inches, less than 6 inches, or less than 5 inches.
The handle portion 12 includes a handle base wall 22. The handle base wall 22 can laterally curve upwardly or downwardly across the handle portion 12 (in a direction perpendicular to the axis x of the handle portion 12). In other embodiments, the handle base wall 22 extends substantially in a plane. In some embodiments, the handle base wall 22 and the head base wall 16 extend coplanar (see
An outer upstanding portion or wall 30 may be, but does not have to be, provided around a portion or all of the outer perimeter of the cup support 10. More specifically, an outer upstanding wall 30 may extend upwardly from one or both of the head base wall 16 or handle base wall 22. By “upwardly” it is meant that the wall extends in a direction that would be towards the user during use. The outer upstanding wall 30 may be continuous around the perimeter of the cup support 10 or multiple wall segments may be used. The outer upstanding wall 30 may extend directly upwardly from one or both of the head base wall 16 and/or handle base wall 22 (e.g., at approximately 90° relative to the plane of the head base wall 16 or handle base wall 22) or may angle inwardly or outwardly relative to the head portion 14 and/or handle portion 12. In some embodiments, the outer upstanding wall 30 angles outwardly at an angle B measured downwardly from the aperture axis y, such as but not limited to at an angle B (i) greater than 5°, greater than 10°, greater than 15°, greater than 20°, greater than 25°, greater than 30°, greater than 35°, greater than 40°, greater than 45°, greater than 50°, greater than 55°, greater than 60°, greater than 65°, greater than 70°, greater than 75°, greater than 80°, or greater than 85, but (ii) less than 90°. The outer upstanding wall 30 serves to impart structural rigidity to the cup support 10 and render the cup support 10 better able to support the weight of a filled specimen cup. Moreover, it also helps to contain errant urine streams on the cup support 10 to prevent any dripping from the edges of the cup support 10, as described below. However, not all embodiments of the cup supports described herein will include an outer upstanding wall 30. Moreover, such an outer upstanding wall 30 need not be provided around the entire perimeter of the cup support. Rather, in some embodiments, it may be provided around all or a portion of the perimeter of the head portion 14 but not along the perimeter of the handle portion 12 (or vice versa).
The height H of the outer upstanding wall 30 (which can be measured from the head base wall 16 or handle base wall 22) can be consistent or vary along the perimeter of the cup support 10. In some embodiments, the upstanding wall has a height H of at least 1 millimeter (“mm”), at least 2 mm, at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm or at least 10 mm, but less than 80 mm, less than 70 mm, less than 60 mm, less than 50 mm, less than 40 mm, less than 30 mm, less than 20 mm, or less than 10 mm. A height H between 2 mm to 30 mm, inclusive; 2 mm to 25 mm, inclusive; 2 mm to 20 mm, inclusive; 2 mm to 15 mm, inclusive; 2 mm to 10 mm, inclusive; 2 mm to 8 mm inclusive; 2 mm to 5 mm inclusive; or 5 mm to 10 mm, inclusive, will be suitable for most applications. The height H of the outer upstanding wall 30 may be consistent or vary around the perimeter of the cup support 10. In some embodiments, the distal edge(s) of the outer upstanding wall 30 terminate in a single plane. By way only of example, in embodiments where the handle portion 12 extends in a plane above the head portion 14, the height H of the upstanding wall portion(s) 30 extending along the perimeter of the head portion 14 may be greater than the height H of the upstanding wall portion(s) 30 extending along the perimeter of the handle portion 12 such that the outer upstanding wall 30 terminates in the same plane.
In some embodiments, a rim 34 extends outwardly from the distal end of the entire, or portions of, the outer upstanding wall 30. Such a rim 34 further imparts structural rigidity to the cup support 10 but also facilitates removal of a cup support 10 from a stack of nested cup supports, as discussed in further detail below.
In some embodiments, the outer upstanding wall 30 is formed by the perimeter edge of the head base wall 16 curving, bending, and/or flaring upwardly, inwardly, and/or outwardly to define the outer upstanding wall 30 (see, e.g.,
In some embodiments, the head portion 14 does not include a head base wall 16. Rather, the aperture 18 can be defined directly by the outer upstanding wall 30 or the inner upstanding wall 40. For example, the head portion 14 may include an outer upstanding wall 30 that extends downwardly, and the aperture 18 is defined by the lower edge of the outer upstanding wall 30. Or, alternatively, the upper edge of the inner upstanding wall 40 may define the upper aperture opening. In some embodiments, the outer upstanding wall 30 and inner upstanding wall 40 meet at a V-shaped intersection such that no head base wall 16 is present. In some embodiments, the inner upstanding wall 40 and the outer upstanding wall 30 (along with the head base wall 16 if provided) form a trough 44 that extends at least partially around the perimeter of the aperture 18. In some embodiments, the base 46 of the trough 44 is recessed below the upper aperture opening that receives the specimen cup. As described further below, in use the inner upstanding wall 40 directs errant urine away from the joint between the cup support 100, 200 and the specimen cup and into the trough 44.
In some embodiments, the cup supports are designed such that they can be nested within each other to permit stacking. More specifically, in some embodiments, at least part of the head portion 14 and/or handle portion 12 of a cup support located higher in the stack seats at least partially within the head portion 14 and/or handle portion 12 of the cup support located immediately below it in the stack. For example, in some embodiments, the head portion 14 and/or handle portion 12 of an upper cup support seats within the outer upstanding wall 30 of a lower cup support. Slightly outwardly flared or angled outer upstanding walls 30 can assist with such stacking, although they are not required. In embodiments provided with inner upstanding walls 40, the inner upstanding wall 40 of the cup support located lower in the stack can be at least partially received within the aperture of the cup support located immediately higher in the stack.
In some embodiments, the cup support is shaped such that the contour of the lower portion of the cup support forms an undercut 50 (see
If the cup supports are provided in a stack, in use the user lifts the cup support from the top of the stack. Rim 34 (if provided) may facilitate this process. The user then drops a specimen cup into the aperture. A single size aperture may accommodate specimen cups of varying diameters. In embodiments where the aperture 18 is smooth and continuous, cups are free to drop through the aperture to a point at which the outer diameter of the cup abuts the edge defining the aperture. This point will be different for cups of different diameters. Regardless, at that point the cup is fully encircled by the cup support such that substantially no gap exists between the cup and cup support. This helps to prevent liquid from seeping down through the joint between the cup and the cup support. Embodiments where tabs or retentions features are provided in the aperture may require the user to apply light pressure to insert the cup within the aperture.
Gripping the handle (typically between the user's thumb and forefinger), the user then positions the cup (supported by the head portion 14) in the anticipated location of the urine stream. The user can re-adjust positioning using the handle and based on the direction of the initial urine flow. One or more ribs 52 (see
If the user initially fails to position the cup opening directly in the “line of fire” of the urine stream, the outer upstanding wall 30 prevents errant urine from dripping off the sides of the cup support. In the embodiment of
In some embodiments, the cup support is adapted to absorb at least some of the liquid that impinges on it. For example, in some embodiments, the cup support is formed from a liquid absorbent material, such as compressed or molded cellulose fibers such as pulp fibers (e.g., raw pulp fibers), such as used to form some egg containers. The material should be of a suitable rigidity and thickness to bear the weight of a filled cup, even when the material gets wet during use. Suitable thicknesses of the material used to form the cup support include, but are not limited to, 1 millimeter to 10 millimeters, inclusive or 1 millimeter to 5 millimeters, inclusive. Thicknesses in the range of 1 millimeter to 4 millimeters will be suitable for most applications. If the cup is improperly aligned and urine impinges on a cup support formed of a liquid absorbent material, it will be absorbed by and into the cup support itself. Moreover, pulp fibers will be exposed in the exposed edges of the cup support, such as the edge defining the aperture 18 and/or the exposed edges of the inner or outer upstanding walls 40, 30 or rim 34. These exposed fibers are particularly effective at absorbing liquid.
During the urine collection process, not part of the cup support comes into contact with the urine that is deposited within the cup. Moreover, the design of embodiments of the present invention results in no urine reaching the user's hand or dripping from the cup or cup support after the specimen is deposited. Indeed, the bottom of the cup remains urine-free. Thus, upon completion, the user can set the cup support with associated cup down to redress without leaving urine of any surfaces. The user can then deposit both the cup support and the cup in the designated location for subsequent testing. It is contemplated that the handle portion may be scored, perforated, etc. such that it can be bent upwardly or downwardly to reduce the footprint of the assembly if necessary. In some embodiments, when the cup is set down, the cup support drops downwardly by virtue of gravity such that the cup and the cup support are automatically separated from each other. The nurse or other clinical personnel can then easily remove the cup for testing its contents and dispose of the cup support. In this way, the cup support is a hygienic, inexpensive, easy to use, single use product.
