发明名称 Skin allergy test device having step-shaped punctures
摘要 A skin allergy test device includes a skin allergy test bar and an antigen container. The skin allergy test bar includes a finger grip, an integral cover having a sealing plug portion, an elongated stem extending therefrom, and a plurality of step-shaped punctures, wherein each puncture has a flat step to act as a stop and an integral sharp tip projecting out from the flat step. Each sharp tip has a length shorter than the thickness of the epidermis layer of the skin of human beings such that each puncture will not penetrate the epidermis layer of the skin of human beings due to the flat step of the punctures acting as a stop during a skin allergy test. The container has an inner compartment for storing antigen solution, a top opening for receiving the sealing plug of the skin allergy test bar securely, and a middle opening intercommunicating the inner compartment and top opening. The middle opening has a diameter slightly greater than which of the elongated stem of the skin allergy test bar and is formed with an inner coarse surface for wiping off the antigen solution left on the surface of elongated stem.
