ABSTRACT:
Described is a lancet cartridge for drawing blood samples from the finger of a patient which includes a first housing for receiving a lancet disk having a plurality of radially extending lancets, each lancet having a tooth projecting from the end thereof, and a second housing engageable with the first housing, the housings being rotatable with respect to each other, the one housing includes a ramp for receiving the end of the lancets whereby the lancet is elevated when the cartridge housing is rotated. A platform is positioned in one of the housings to receive the lancet as it is elevated by the ramp to thereby place the lancet in a cocked position. The second housing member includes at least one opening through which the end of the lancets can project to pierce the patient's finger. A trigger is positioned to be activated when a finger is placed in the opening to release the cocked lancet from the platform and pierce the patient's finger. As the housing is rotated the lancets are successively positioned on the platform so that the lancet device can be used to take multiple blood samples. If desired, the device can be disposable.
