    摘要: A device for sampling blood from the skin of a patient by puncture. The device includes one or more lancets for lancing the skin and a fluid-conducting plate unit for transporting blood from the lancing wound. The plate unit has one or more channels for conducting fluid to one or more target locations. Preferably there is a first channel for conducting away a first portion of fluid that contains more of a fluid that is emitted initially (initial fluid) from the puncture wound and a second channel for conducting a second portion of fluid that contains less of the initial fluid from the puncture wound. Blood is drawn into the channels by capillary force. The device can be used to lance the skin and obtain a representative sample of blood with relatively simple procedures.

    摘要: A device for puncturing the skin of a patient. The device includes first and second protrusions, each protrusion puncturing the skin when pressed against the skin. The first and second protrusions are arranged such that the first protrusion punctures the skin at a location less than a predetermined distance from the second protrusion. The distance is chosen to be less than the discriminatable distance between distinct pain perception points in the patient, such that the patient perceives a single puncture when the first and second protrusions puncture the skin. In one embodiment of the invention, the device includes a base lip that applies a lateral force to the skin when the base lip is pressed against the skin. In this embodiment, the protrusions are pressed into the skin as the base lip is pressed against the skin.
