Definitions

  • THIS INVENTION relates to a test kit for administering prick skin tests for detecting allergen hypersensitivity.
  • the current method of administering prick skin tests for detecting allergen hypersensitivity is to apply a drop of allergen extract to a marked spot on the volvar surface of the extended forearm, and to just break the skin surface with a sterile needle, thus administering a minute amount of extract into the dermal layer.
  • the extract then binds to IgE antibody attached to the surface of mast cells and induces histamine release manifested by a wheel and flare reaction in the skin if the subject has produced, afore- hand, IgE antibodies with specificity for that particular allergen i.e. he/she has been sensitized.
  • a positive reaction is taken to mean that the individual is allergic to that allergen.
  • Subcutaneous skin tests are performed by administering via hyperdermic syringe approximately 50 ul of allergen ex ⁇ tract beneath the dermal layers.
  • Subcutaneous skin tests employ in general more dilute allergen extracts than do prick skin tests. Positive reactions are read as for prick skin tests and the magnitude of the reaction in both instances is measured by the diameter in mm of the wheal produced.
  • the object of the present invention is to provide a sim ⁇ plified precedure for accurate, safer administration of prick skin tests under conditions of high reproductivity yet sufficiently simple to be operable with no additional reagents, e.g. pollen extracts, syringe, needles and the like.
  • the invention resides in a skin test kit comprising a number of pre-packaged sachets of sterile allergens which can be clipped together end to end to provide a chain of selected allergens, aligners adapted to be connected to each end of the sachet chain incorporating means for marking the skin, a solid strip having a plura ⁇ lity of projecting needles spaced to correspond to the spacing of the sachets, and means for applying pressure to the needle strip to force each of the needles through the bubble of the corresponding sachet and into the skin.

  • the allergen sachets contain a small quantity of sterile allergen sealed as a bubble 49 in sealed soft plastic sachets 50 (see Fig. * 1).
  • the allergen is preferably made viscous by the addition of a suitable solvent such as glycerine to ensure that the allergen will adhere to the needle and to prevent the allergen spreading over the surface of the skin.
  • a suitable solvent such as glycerine
  • Each sachet 50 carries on one edge a male plastic clip 51 and on the opposite edge a female plastic clip 52 (see Fig. 1) to allow sachets containing different allergen extracts to be clipped together to form a continuous allergen sachet chain. They also contain a small female plastic clip 53 on adjacent sides to the chain connectors which are used to attachment oC a needle strip. These small clips are located on the same axis as the allergen bubble.
  • Aligners Aligners 54 (see Fig. 2) are attached to each end of the sachet chain. These aligners 6 carry on adhesive surface covered by a removable tear-off backing 55.
  • One set of aligners to attach to the head of the sachet chain, carries connectors 56 in the form of female plastic clips, and the adhesive surface contains an alcohol soluble green dye.
  • roller The stainless steel, or good quality plas ⁇ tic, roller 61 is mounted into the frame 62 via a spring loaded axle 63.
  • the bracket of the frame carries a wide runner 64 to ensure that the roller can only be applied at a fixed maximum pressure (Fig. 4).
  • Step 1 The operator selects from the various allergen sachets those deemed by case history to be appropriate for the given patient.
  • the sachets are clipped together as illustrated (Fig. 5) and it is preferable to include both a histamine and solvent control sachet.
  • the order of in ⁇ dividual allergen sachets forming the chain is irrelevant as each sachet is clearly identifiable.
  • Aligners are then clipped to the ends of the sachet chain to provide the green aligner at the head and the red aligner at the tail of the sachet chain.
  • the allergen sachet chain is then sterilized by wiping with a sterile swab.
  • Step 2 The appropriate length of the needle strip is prepared, the tear off sterile cover removed, and the needle strip is then clipped on to the allergen sachet chain via the small plastic clips 53 and 59. It should be noted that this attachment must not puncture the allergen sachets.
  • Step 3 Wipe the surface of the skin with a sterile swab. Tear off the backing strips covering the adhesive surface and attach the sachet chains (with attached needle strip) to the cleaned volvar surface of the arm pressing firmly over the area of the adhesive surfaces of the aligners.
  • Step 4 Apply the roller to the head of the sachet chain, exert the maximum pressure and run the roller down the entire length of the sachet chain. This action will force the sterile needle points through the allergen sachet and to the required depth in the skin surface transferring in so doing, a fixed and predetermined amount of allergen, adhering to the needle surface through its viscosity, into the skin.
  • Step 5 Remove the sachet strip from the forearm and confirm that the green and red dyes have marked the skin. Pull off needle strip and discard, but do not dismantle allergen sachet chain which is temporarily attached to the patient's file.
  • Step 6 After 15-20 minutes, realign allergen sachet chain with the green and red dye marks on the arm and read the magnitude of the skin reactions, including that of the histamine and solvent controls, for each coded allergen.
  • Step 7 Record data in patient's chart, remove coloured dye with alcohol swab and discard sachet chain.
  • allergen sachet chain If more than one allergen sachet chain is to be applied to the patient's forearm, identify each chain with a numeral, applied with a marker pen to the top surface of the green aligner and to the corresponding point of attachment to the skin.
  • the sachet com ⁇ prises a lower layer 11 of heat deformable plastic in which a semispherical bubble 12 has been formed.
  • an upper layer 10 of the plastic is placed over the lower layer and the two layers heat sealed together over the area designated 13 in the drawings.
  • the layers are cut so that the upper layer has an extension flap 14 at one end of the sachet and the lower layer has an extension flap 15 at the opposite end of the sachet.
  • the extension flaps are coated with a pressure sensitive adhesive so that a number of sachets can be linked together in a chain.
  • the sachets at each end of the chain be provided with a longer flap provided with an opening through which it is possible to mark the skin of the patient being tested with a marking pen or the like.
  • a nurse or the like it is possible for a nurse or the like to make up strings of sachets containing the most appropriate allergens and/or control substances for each patient.
  • the needle assembly comprises a strip of plastic 16 having a series of hydro- dermic needles 17 projecting from one thereof.
  • the nee ⁇ dles are very fine and project approximately 2 -3 mms from the plastic strip.
  • a cover strip 18 having a slot 19 is provided to protect the needles during transport or storage.
  • the aligner or guide comprises a strip of plastic 20 corresponding approxima ⁇ tely to the length of the chain and provided with a longi ⁇ tudinal slot 21 and transverse slots 22 and 23 at each end to align with one of the slots in the extended flap on each of the each sachets in the chain.
  • the chain of sachets is placed in position on the patients arm with the bubbles uppermost and the aligner or guide positioned with its transverse slots aligned with the slots in each sachets. If desired the aligner may be held in position with adhesive tape or adhesive applied to each end of the aligner.
  • the needle assembly is then posi ⁇ tioned in the slot 21 with the needles facing towards the patients skin.
  • a roller is then run along the upper surface of the aligner so that the needles pierce the bubble and enter the patients skin carrying sufficient allergen to produce a reaction.
