  • Patent number: 7666149
    Abstract: A cassette containing cartridges for sampling blood from a patient. The cassette includes a container for storing a plurality of cartridges and at least one cartridge in the container. The cartridge includes a cartridge case and a lancet. The lancet has a tip and is housed in the cartridge case. The lancet can be driven to extend the tip outside the cartridge case for lancing the skin of the patient to yield blood. The container has a compartment that contains at least one cartridge. A cartridge from the compartment can be loaded onto a glucometer that drives the lancet in the cartridge to lance the skin of a patient.

  • Publication number: 20040019300
    Abstract: A microfluidic system isolates blood cells of a minute volume of a blood sample by using a passive-settlement approach or an active-flow approach, rather than an approach that requires centrifugation. In the passive-settlement approach, the microfluidic system yields a hematocrit measurement by detecting the volume of red blood cells that settle under the influence of gravitational force. According to the active-flow approach, blood cells are isolated at one or more porous regions having pores dimensioned which preferentially pass constituents of the blood sample.

  • Patent number: 6071294
    Abstract: A cartridge for sampling and analyzing blood from the skin of a patient. The cartridge has a cartridge case, a lancet, and associated with the cartridge case an analytical region for analyzing the property of blood. The lancet has a tip for lancing the skin and is housed in the cartridge case. The lancet is operatively connected to the cartridge case such that the lancet can be pushed to extend its tip outside the cartridge case for lancing the skin to yield blood. The blood from the lancing wound is transferred to the analytical region and be analyzed.

  • Patent number: 5971941
    Abstract: A blood sampling apparatus for sampling blood from the skin of a patient for analysis. The apparatus includes a cartridge and a housing with a driver. The cartridge has a cartridge case, lancet, and a compartment associated with the cartridge case for receiving blood. The lancet is housed in the cartridge case and operatively connected thereto such that it is drivable to extend outside the cartridge case through a lancing opening for lancing the skin to yield blood. The housing has a driver for urging the lancet to extend outside the cartridge case. During lancing, the cartridge is preferably detachably held in the housing such that the cartridge can be disassociated from the driver after sampling blood.

  • Patent number: 5871494
    Abstract: A blood analysis apparatus for obtaining blood for analysis from the skin of a patient with a controlled degree of lancing. The apparatus including a cartridge and a driver. The cartridge includes a cartridge case and a lancet. The lancet has a tip and is housed in the cartridge case. The lancet can be driven to extend the tip outside the cartridge case through an opening for lancing the skin of the patient to yield blood. The driver drives the lancet to move the tip distally to lance the skin. The driver is triggerable by the skin which is to be lanced exerting a force exceeding a preset amount against the triggering mechanism of the apparatus, to drive the lancet toward the skin.
