Definitions

  • This invention relates to collection of specimens. It relates particularly but not exclusively to apparatus for use with a specimen collection container for collecting urine, semen or the like.
  • Urine samples can also be used in preliminary testing for pregnancy and to detect traces of certain drugs in a person's system.
  • the present invention aims to provide a specimen collection apparatus which, in its various embodiments, provides a useful alternative for collecting a specimen.
  • guide apparatus for use with a container for collecting a specimen.
  • the apparatus includes a funnel portion, and a neck portion which is locatable inside an opening of the container.
  • Attachment means is provided for attaching the guide apparatus to the container and a region of weakness facilitates separation of the funnel portion from the neck portion.
  • the funnel portion of the guide apparatus can be separated from the neck portion at the region of weakness, after collection of the specimen.
  • the region of weakness may be provided in the form of a frangible line, perforations, a scored line or other line of weakness. Accordingly, the funnel portion may be separated from the neck portion by tearing along the weakness thus allowing closure of the container with a lid.
  • a second aspect of the invention provides guide apparatus for use with a container for collecting a specimen, the apparatus including a funnel portion, and a neck portion locatable inside an opening of the container.
  • Attachment means is provided for attaching the guide apparatus to the container and at least the funnel portion of the guide apparatus is separable from the container after collection of the specimen. Separation of the guide apparatus from the container enables closure of the container by application of a lid.
  • the attachment means includes adhesive to adhere the neck portion of the guide apparatus to an inner region of the container opening.
  • the adhesive may be in the form of an adhesive strip applied to the neck portion and activated by removal of a waxed paper or other backing.
  • the adhesive may be a gum activated by moistening with water or the like.
  • the adhesive may be activated by dipping the neck portion of the guide apparatus in water. It is to be understood, however, that any suitable attachment means may be used as an alternative.
  • the attachment means is sufficiently strong that in use, the container can be positioned for collection of a specimen by a user holding a portion of the guide apparatus without the container detaching from the funnel, even as the collected specimen increases the weight of the container.
  • the guide apparatus may be attached to a container well in advance of collection and prior to sterilisation of the container to ensure collection of an uncontaminated sample.
  • the guide apparatus may be attached to a container immediately prior to collection of a sample which may be convenient in some circumstances.
  • the funnel portion is expandable from a storage configuration in which the guide apparatus is attached to the container and retained therein, permitting closure of the container by application of a lid. When a sample is to be collected, the lid is removed and the funnel portion is gently pulled, causing it to expand to an in- use configuration where the funnel portion guides the specimen being collected into the container.

  • the split permits overlap of regions of the funnel portion thus enabling the funnel portion to assume and maintain the storage configuration. Preferably this is without crushing or otherwise mis-shaping the funnel portion.
  • the split also enables the funnel portion to be assembled from a blank.
  • a pair of tabs may be provided with one tab located either side of the split.
  • these tabs are designed in such a way that they slot together or interlock to form one easily operated tab.
  • the tabs are located on an outer rim of the funnel portion, either side of the split, and help to complete and maintain the shape of the funnel opening.
  • the tabs may be located along the split.
  • the funnel opening is elliptical in shape. This is particularly suitable for funnels used to collect urine samples from female subjects.

  • the flange may be an annular flange or consist of one or more flange sections.
  • the flange includes an internal threaded portion configured to engage with a thread on the container.
  • the one or more flange sections may attach the guide apparatus to the container by engaging or "clipping" under the threaded portion of the container.
  • the guide apparatus may be removed from the container by disengaging the flange from the thread around the container opening e.g. by unthreading the annular flange or deforming the flange sections to release the guide apparatus from the container.

Abstract

La présente invention concerne un appareil de guidage (200) destiné à une utilisation avec un récipient (101) pour prélever un échantillon, qui comprend une partie en entonnoir (201) et une partie de col (202) pouvant être situées dans une ouverture du récipient (101). Des moyens de fixation (203) sont prévus pour fixer l'appareil de guidage (200) au récipient (101) et une région de faiblesse (204) est également prévue pour faciliter la séparation de la partie en entonnoir (201) à partir de la partie de col (202) après le prélèvement de l'échantillon. La partie en entonnoir (202) peut ensuite être jetée, par exemple, dans les toilettes. Des languettes (205) peuvent également être formées sur l'appareil de guidage (200) pour être tenues par un utilisateur lors du prélèvement d'un échantillon, maintenant ainsi l'appareil de guidage (200) et le récipient (101) en position, sans que le récipient (101) se détache accidentellement de la partie d'entonnoir (201).
