    摘要: A reusable ceramic skin-piercing device. The skin-piercing device is capable of piercing the skin so as to make a sample of biological fluid available for an assay. In one embodiment, the skin-piercing device includes a skin-piercing element which is heated prior to use to a sufficiently high temperature to kill or deactivate pathogenic microorganisms. The device is heat-sterilized, being heated by passing an electrical current through a resistive element in thermal contact with the heat-conducting ceramic piercer. In another embodiment, the skin-piercing device includes a sleeve of elastomeric material with a sterilizing agent disposed in contact with the skin-piercing element. The sterilizing agent sterilizes the skin-piercing element after use. The skin-piercing element is made of a hard refractory ceramic material. The ceramic material is optionally a composite, for example, a composite of a ceramic material and a metal, or multiple ceramic materials.
