Definitions

  • the present invention relates to apparatus for use in collecting samples for analysis. More particularly it relates to apparatus for collecting samples to detect the presence of one or more drugs.
  • the apparatus of the present invention may be utilised for collecting a range of samples for analysis, for convenience it will be described in terms of apparatus used for detecting the presence of drugs.
  • drug and “drugs” will be used to refer to any material which has been added to a beverage without the consent of the consumer. As will be explained in more detail below, the term will include alcohol, prescription pharmaceuticals, over the counter pharmaceuticals, illegal substances and the like.
  • test strip which is particularly useful for the detection of gamma hydroxybutyrate or methylene dioxymethamphetamine.
  • the test strip may be replaced with a coaster having a plurality of testing means.
  • WO 03/021254 describes a test apparatus in which one or more solid, chemical colorimetric indicators are embedded in the surface of a porous substrate,
  • WO 2005/059541 describes a test kit for detecting the presence of one or more drugs in a beverage comprising a support having a plurality of detector strips permanently attached thereto wherein the support is sized such that when it is folded into two parts a first part is laid over the strips which are attached to the second part.
  • the strips may be releasably attached to the support,
  • a further problem is it is necessary to be certain that the liquid used to wet the swab could not have contained any drug which would lead to a false positive result as this would result in difficulties during any subsequent legal proceedings. It may also be desirable to control the amount of liquid applied to the swab to control the level of "wetness" of the swab. It has therefore been suggested that a measured amount of liquid can be supplied in the handle of the swab. Whilst this addresses the problems associated with cleanliness and volume of the liquid, it is a requirement that the device has to include means for enabling the liquid to come into contact with the swab and the operation of this can further complicate the operation.
  • test will generally be paper or the like impregnated with the appropriate reagent(s) which react when brought into contact with the drug being detected.
  • apparatus comprising a tube having at least two connecting sections:
  • the first section including a swab mounted at an end thereof;
  • the second section comprising a test
  • said first and second sections being arranged such that they are separable.
  • the tube may be of any suitable configuration, In one arrangement it may be of cylindrical configuration but tubes of other cross-sections such as triangular, square, pentagonal, hexagonal and the like may be used.
  • first and second sections may be connected via a frangible flange.
  • the flange may be broken by any suitable means. In one arrangement, it may be broken by the relative twisting of the two sections.
  • first and second sections may be configured such that one is a snap fit with the other.
  • one of the first and second sections may include a pin which slides into a corresponding channel on the second section and is retained therein.
  • the retention of the pin may be by means of a clip or the like or the channel may have an angled section such that in use once the pin is pushed down to the end of the first portion of the channel, one of the first and second sections can be twisted relative to the other such that the pin moves into the angled section of the channel thereby preventing the sections from being separated by pulling apart.
  • At least one of the first and second sections may include a vial comprising a liquid.
  • the vial may be caused to release the liquid as the first and second sections are separated.
  • the vial may be broken by any suitable means.
  • the vial may be punctured or otherwise caused to break.
  • the twisting action may cause the puncturing or breaking of the vial.
  • the vial may not be broken as the first and second sections are separated.
  • the section or sections containing the vial will include means to enable the user to choose if and when to break the vial. This may be achieved by any suitable means.
  • the vial may be broken by the user depressing a portion of the section. This pressure alone may be sufficient to break the vial.
  • the section may be constructed such that means such as pins, springs, and the like may be present such that they are activated when the user depresses a portion of the section.
  • the vial may be made of any suitable material, Suitable materials include glass and plastics.
  • the swab mounted at the end of the first section of the tube may extend across the width of the tube but generally it will be arranged such that it is mounted on an extension from the first section of the tube so that before the sections are separated, the swab is located within, and protected by the second section.
  • the swab may be made of any suitable material, Generally it will be made of an inert absorbent material such as cotton.
  • the apparatus may include the test material.
  • the test material may be located within the second section or may be located on a surface thereof. Generally it will be located at a suitable position within the second section such that once the swab has been contacted with the surfaces to be screened, the first and second sections are reassembled such that the swab and the test come into contact with each other.
  • the test may be located in the second section of the tube remote from the original position of the swab and accessible from the end of the tube remote from that from which the swab was removed.
  • the swab is contacted with the test by being applied to the end remote from that from which it was removed.
  • a cap may be provided to protect the test when not in use.
  • the test is preferably one which shows a result by means of a colour change and the user can then remove the swab to assess whether the required colour change has occurred.
  • the result of the test may be seen by viewing through the opening through which the first section has been removed or under the cap where present.
  • the section including the test, or a portion thereof may be formed from a transparent material such that the results can be readily viewed.
  • the section may be opaque and a portion of the section may be openable so that the results can be viewed.
  • the portion which openable can be hinged or in one other arrangement may be slidable. In another arrangement it may be completely removable.
  • the cover is openable, if a positive result is noted, it will generally be closed in preparation for evidence submission.
  • means for locking the openable portion in place may be provided to prevent unauthorised access to the test results. Any suitable means for locking the openable portion may be provided.
  • the test may not be visiable to the user but the apparatus may include means for detecting the result and then transmitting the result to a display provided on the surface of one of the sections.
  • test compartment is a schematic representation of the test compartment being exposed in one arrangement
  • the apparatus comprises a tube 1 having at least two sections, a first section 2 and a second section 3,
  • the second section 3 has a cap 4 Iocated at the end thereof remote from the first section. Twisting the first section 2 relative to the second section 3 will cause the seal 5 between the two sections to break allowing them to be separated.
  • a vial of liquid (not shown) is located within one of the sections and is punctured as the sections are separated,
  • Figure 2 which also shows the located of a swab 8.
  • the swab which will now be wetted by the correct amount of liquid can be used to swab surfaces.
  • the swab may be applied to a variety of surfaces including wood, metal, plastics, textiles and even human skin as illustrated in Figure 3,
  • the swab can then ready to be connected with the test,
  • the cap 4 can then be removed from the second section 3.
  • Figure 4a shows the test surface located under the hinge.
  • the swab can then be applied to the test surface as shown in Figure 5,
  • the results can then be assessed as shown in Figure 6.
  • the test is a colour change and so no colour change 8a indicates a negative result.
  • a colour change 8b indicates a positive result.
  • the apparatus comprises a tube 10 which comprises a first section 12 and a second section 13.
  • the first section 12 includes a fluid release pressure point 14. Depressing this point will cause the vial, not shown, to be broken,
  • the second section 13 includes the test which is located below the protection cover 15.
  • the first and second sections are pulled apart to release the swab 16 as illustrated in Figure 9.
  • the portion of the first section 12 remote from the swab 16 may be shaped such that the removed second section can be clip thereto while testing takes place.
  • the apparatus can be used directly as shown in Figure 1 1. If it is dry, the fluid pressure point 14 can be depressed to release fluid and thereby damp the swab.
  • the openabie section of the second section can then be opened to reveal the test. Once a positive test is obtained as shown in Figure 14, the first and second sections can be reconnected and the openabie section closed in preparation for evidence submission.
