Definitions

  • the present invention relates to a device for delivering a medicament or a diagnostic agent to the skin or mucosa of an animal such as a human being, wherein a cham- ber filled with the medicament or the diagnostic agent is separate from the housing with a rod capable of transferring the medicament or the diagnostic agent to the animal.
  • the invention relates to a device for delivering allergens in allergy tests.
  • allergies are diagnosed by manually applying a number of different allergen solutions on the palm side of the patient's forearm. After this, an injection needle is pricked through the individual drops and about 1 mm into the skin so that a cavity is formed for absorbing some of the solution.
  • the skin will after 10 to 15 minutes become red and swollen around the injection spot to an extent that depends on the quantity or the concentration of the solution that can be absorbed by the cavity.
  • the degree of the allergic reaction can be given as a function of the extent of the swel- ling.
  • the degree of the allergic reaction can therefore not be estimated with the wanted accuracy and reproducibility.
  • U.S. Pat. No. 5,099,857 discloses a construction with a movable injection needle and a sealed capsule containing an allergen solution. At injection, the needle will rupture the capsule, and the solution will therefore run out and form a drop on the skin, after which the needle via the drop will penetrate the skin in the same way as mentioned above. Also in this case, the estimate of the possible skin reaction will be inaccurate. Thus, there is a need for improvements in such devices.
