This invention relates to apparatus for collecting personal samples. Some embodiments provide holders for collecting personal samples (e.g. urine and/or stool). This invention may particularly have applications in the self-collection of personal samples.
The collection of personal samples, such as urine and/or stool, can be required for a wide variety of reasons. By way of non-limiting example, the collection of personal samples is sometimes required to conduct some types of medical tests. Currently, the self-collection of personal samples typically involves strategically placing the appropriate collection vessel to receive urine and/or stool. This may prove to be challenging due to the required position of the collection vessel combined with one or both of reaching such positions and maintaining such positions during collection.
There is a general need and desire for apparatus for the collection of personal samples that aid in, ease and simplify the process of collecting personal samples.
This invention has a number of aspects. These include, without limitation:
Apparatus for the collection of personal samples; and
Methods for the collection of personal samples.
One aspect of the invention provides a personal sample holder apparatus for aiding in the collection of personal samples. The personal sample holder apparatus comprises: first and second elongated arms pivotally coupled to one another by a pivot joint to permit relative pivotal movement between the first and second arms about a pivot axis; a sample collection vessel holder located at a sample-collection location of the second arm, the sample-collection location spaced apart from the pivot joint; wherein the pivot joint is lockable at a plurality of discrete locking configurations to prevent relative pivotal movement between the first and second arms under application of forces associated with personal sample collection and each of the plurality of discrete locking configurations is at a corresponding relative angular orientation between the first and second arms.
The pivot joint may be configured to facilitate relative pivotal movement between locking configurations upon the application, to one or both of the first and second arms, of a force sufficient to deform one or both of the first and second arms.

The pivot axis may extend through a cross-sectional center of the cylindrical bearing surface. The first play may comprise one or more connecting protrusions located at locations radially spaced apart from the pivot axis and angularly spaced apart around the pivot axis. The connecting protrusions may extend from the cylindrical bearing surface in directions that have at least a directional component that is parallel with the pivot axis.
The first plate may form a snap-together fitting with the second plate.
The first plate may comprises one or more resting protrusions located at locations radially spaced apart from the pivot axis, angularly spaced apart around the pivot axis and between pairs of connecting protrusions. The resting protrusions may extend from the cylindrical bearing surface in directions that have at least a directional component that is parallel with the pivot axis. The resting protrusions may extend, from the cylindrical bearing surface, for a shorter distance than the connecting protrusions.
The connecting protrusions may be integrally formed with the cylindrical bearing surface.
Distal ends of the connecting protrusions may be widened relative to shaft portions of the connecting protrusions.
The connecting protrusions may extend through openings on the second plate to secure the first plate to the second plate.
The openings may be radially spaced apart from the pivot axis and angularly spaced apart from one another around the pivot axis.
The second arm may comprise a bore-defining surface.
The cylindrical bearing surface may bear against the bore-defining surface to facilitate relative pivotal motion between the first and second arms about the pivot axis.
The first plate may be integrally formed with the first arm.

The accompanying drawings illustrate non-limiting example embodiments of the invention.
Throughout the following description, specific details are set forth in order to provide a more thorough understanding of the invention. However, the invention may be practiced without these particulars. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the invention. Accordingly, the specification and drawings are to be regarded in an illustrative, rather than a restrictive sense.
One aspect of the invention provides a bodily substance collection apparatus to be used, for example, to aid in the self-collection of urine or stool. The apparatus may comprise a first arm and a second arm. The second arm may be pivotally coupled to the first arm at a pivot joint for relative pivotal motion between the first and second arms about a pivot axis. The apparatus may further comprise a sample collection vessel holder located at, or attached to, an end of one of the first and second arms.
The pivot joint may comprise first and/or second plates positioned at the ends of the first and second arms. The first and second plates may each comprise teeth on a face of the plate, which may interact with (e.g. contact) the second and first arms to maintain the relative angular orientation between the first and second arms and, in the absence of sufficient external force, prevent relative pivotal motion between the first and second arms during personal sample collection.
The first and the second arms may each comprise a sidewall that extends transversely from the first or second arm. The sidewalls of the arms may engage with the teeth of the pivot joint plates.
Personal sample holder apparatus 10 comprises a handle arm 11A and a sample-collection arm 11B (referred to collectively as arms 11 or generally individually as an arm 11). Arms 11 are pivotally coupled to one another at pivot joint 12. Arms 11 may pivot relative to one another around pivot axis 12A.
In the particular case of the illustrated embodiment, pivot joint 12 comprises a first plate 13A and a second plate 13B (collectively plates 13). First and second plates 13A, 13B of the illustrated embodiment are respectively located at or near the ends of handle and sample-collection arms 11A, 11B and portions of plates 13 may extend radially away from pivot axis 12A. In some embodiments, plates 13 may surround pivot axis 12A.
As will be explained in more detail below, in the case of the illustrated embodiment, first plate 13A is integrally formed with (i.e. is a part of) handle arm 11A and second plate 13B is separately embodied. In some embodiments, second plate 13B is integrally formed with (i.e. is a part of) sample-collection arm 11B and first plate 13A is separately embodied. In some embodiments, first and second plates 13A, 13B are integrally formed with handle and sample-collection arms 11A, 11B. In some embodiments, both of plates 13 may be separate parts from arms 11. In some embodiments, both of plates 13 may form a part of handle arm 11A, in which case both of plates 13 may interact with sample-collection arm 11B. In some embodiments, both of plates 13 may form part of sample-collection arm 11B.
Cylindrical bearing surface 23 and/or protrusions 21 may interact (e.g. connect) with one or both of sample-collection arm 11B and second plate 13B to connect handle arm 11A to sample-collection arm 11B and/or second plate 13B. Connecting protrusions 21A may comprise barbs or widened portions 24 at or near their distal ends to facilitate this interaction. Connecting protrusions 21A may also comprise shafts 25.
Second plate 13B may be shaped to define notches 35 which are located at locations that are radially spaced apart from pivot axis 12A and angularly spaced apart from one another around pivot axis 12A. Connecting protrusions 21A of handle arm 11A (
In the illustrated embodiments, first plate 13A (best seen in
The number of indents 15 and/or teeth 14 may vary between embodiments. In some embodiments, the number of teeth 14A and the number of teeth 14B may be between 3-10. In some embodiments, the number of indents 15A and the number of indents 15B may be between 3-10. The angular extension of teeth 14 and indents 15 around pivot axis 12A may vary between embodiments. In some embodiments, the combined angular extension of teeth 14A and indents 15A and/or teeth 14B and indents 15B around pivot axis 12A may be in a range of 0°-270°. In some embodiments, the combined angular extension of teeth 14A and indents 15A and/or teeth 14B and indents 15B around pivot axis 12A may be in a range of 90°-270°.
As shown best in
Sidewalls 16 may remain within indents 15 unless or until a sufficient force (which is greater than that normally associated with personal sample collection) is applied to one or both of arms 11. In this way, indents 15 may maintain the relative angular orientation of arms 11 during personal sample collection. When a sufficient force is applied to an arm 11, such arm 11 may pivot relative to pivot axis 12A. The application of such a force may result in the elastic deformation of various components of apparatus 10 (e.g. arms 11, plates 13, sidewalls 16, teeth 14, protrusions 21A and/or the like). The elastic deformation may allow relative pivotal motion between handle and sample-collection arms 11A, 11B about pivot joint 12 (pivot axis 12A). When external force ceases to be applied to an arm 11, restorative forces may cause the corresponding sidewall 16 to project into a nearest indent 15, thereby locking the relative angular orientation of arms 11 relative to other another again.
A force may be considered to be sufficient if it is above a suitable threshold. The threshold may be equal to or greater than a force that may generally be applied to an arm 11 during the collection of a personal sample. Setting a threshold in this manner may ensure arms 11 maintain their positions within indents 15 (and that the relative angular orientation of arms 11 about pivot joint 12 is locked) during the collection of a personal sample. The threshold may vary at different relative angular orientations of arms 11. For example, the threshold may be relatively large when apparatus 10 is in a typical sample collection configuration and may be relatively low when apparatus 10 is in a storage configuration. The threshold may vary between embodiments. These thresholds may be designed by suitable sizing of one or both of one or more sidewalls 16 and one or more teeth 14 (or, correspondingly, the depth of one or more indents 15) and/or the materials from which personal sample holder apparatus 10 is constructed.
Teeth 14 and/or sidewalls 16 may comprise one or more beveled edges. Beveling may aid arms 11 pivot relative to pivot axis 12A. For example, beveling may reduce the force threshold required to be applied on an arm 11 for it to pivot relative to the other arm about pivot axis 12A. For example, beveling may aid guide sidewalls 16 into indents 15.
Indents 15 may be shaped and/or sized to maintain the angular position of a sidewall 16. To this effect, some or all of indents 15 may be sized to be approximately the thickness of a sidewall 16. In some embodiments, at least one indent 15 may be sized to fit two sidewalls 16 in which case the at least one indent 15 may be sized to be approximately the combined thickness of sidewalls 16.
Teeth 14 and indents 15 may define discrete relative angular positions (orientations) for arms 11 around pivot axis 12A. More specifically, in the case of the illustrated embodiment, the engagement of sidewalls 16B of second arm 11B with teeth 14A, 14B (projection of sidewalls 16B into indents 15A, 15B) defines discrete relative angular positions (orientations) for arms 11 about pivot axis 12A. The angular size and/or number of teeth 14 and indents 15 may define the relative angular spacing and/or number of discrete relative angular positions (orientations) for arms 11 about pivot axis 12A. The discrete relative angular positions for arms 11 may have regular angular intervals or these angular intervals may vary. For example, at least one angular dimension about pivot axis 12A may vary between two teeth 14 and/or two indents 15. For example, in an angular dimension about pivot axis 12A, as the angular dimension of a tooth 14 increases so does the angular interval between adjacent indents 15.
The relative angular range over which arms 11 may be pivoted may depend on the extension of teeth 14 and indents 15 around pivot axis 12A in handle arm 11A and/or second plate 13B. In some embodiments, this relative angular range may be in a range of 0°-270°. In some embodiments, this relative angular range may be in a range of 0°-180°.
As discussed above, connecting protrusions 21A (e.g. the surfaces of shafts 25 and/or barbs or widened portions 24) may be shaped such that restorative deformation forces associated with the “snap-together” connection between connecting protrusions 21A and notches 35 tend to pull second plate 13B toward first plate 13A (e.g. in directions parallel with pivot axis 12A). This same restorative deformation force may similarly force sidewalls 16 into engagement with teeth 14 (force sidewalls 16 to project into indents 15).
As discussed briefly above, handle arm 11A has an elongated and curved shape and comprises a handle 22 which is spaced apart from pivot joint 12. Handle 22 may provide a grip for personal sample holder apparatus 10. Handle 22 may advantageously improve the stability of personal sample holder apparatus 10 while in use by a user which in turn may make personal sample holder apparatus 10 easier to use.
As discussed briefly above, sample-collection arm 11B has an elongated and curved shape and comprises a holder 32 which is spaced apart from pivot joint 12. In some embodiments holder 32 may be attachable and detachable to sample-collection arm 11B. For example, holder 32 may be attached with suitable snap-together fittings located on one or both of holder 32 and sample-collection arm 11B. The ability to attach and detach holder 32 may allow various vessel holders to be substitutable as
holder 32, for example vessel holders that vary in size.
One or both of arms 11 may be curved. Curvature(s) in one or both of arms 11 may help position holder 32 and handle 22 in fixed positions from which it is easier to collect personal samples. Curvature(s) in one or both of arms 11 may aid in the storage of personal sample holder apparatus 10. For example, curvatures in arms 11 may help personal sample holder take up less space (see e.g.
The components of personal sample holder apparatus 10 may be injection molded, press molded or otherwise fabricated and may be made out of any suitable material, such as hard plastic, metal and/or the like. Personal sample holder apparatus 10 may be made with one or more moulds. For example by injection moulding or pressed moulding.
