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.

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.

摘要:
An apparatus having a shaft that can sense the depth of penetration, for penetrating into an object (the substrate). The substrate being penetrated has impedance that varies according to the depth under a surface of the substrate. The shaft has a tip for penetration and has conductive ends near to the tip of the shaft. A change of impedance of material of the object between the conductive ends can be sensed to provide information on the depth of penetration. A processor can be provided external to the object being penetrated by the shaft to gather and process the impedance information to determine whether the desired depth has been achieved.
摘要:
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.
摘要:
A method and apparatus (2) for obtaining a sample of blood. An embodiment includes an apparatus (2) which integrates lancing (12), sample collection, and analysis. The presence of patients finger on the active sampling area can be sensed by monitoring the pressure applied by the finger on the device (2).

摘要:
Blood samples can be collected without substantial contamination from ambient air, such that the blood sample may be analyzed accurately for gaseous components such as oxygen and carbon dioxide. An embodiment of the device has integrated actuation, lancing, and sample acquisition components, which in some embodiments are miniaturized and/or disposable.
