A body fluid sampling device for use on a patient includes at least one penetrating member positioned in the cartridge and a sample port for receiving a body fluid. A channel is coupled to the sample port and the sample chamber. At least a portion of the channel is a capillary channel positioned adjacent to the sample chamber. A mesh membrane is and provides that the body fluid contacts the channel regardless of an orientation of body fluid sampling device.

Method and apparatus for improving fluidic flow and sample capture

A body fluid sampling device is provided. A mesh () may be used to guide blood or fluid to travel directly form the wound to an analyte detecting port on the cartridge (). Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member () for measurement.

Method and apparatus for an improved sample capture device

A system and method is provided for the capture of bodily fluid upon lancing of a patient. In one embodiment, the fluid sample capture aperture mesh () ring is placed in the pathway of a finger penetrating member (). The aperture mesh ring has a center clearance area that allows the penetrating member to pierce the skin unobstructed. The aperture mesh ring may contain a series of fluid sampling meshes as to allow the release bodily fluid to 'wick' into the fluid sampling meshes for transport to the respective sensor. The invention may also relate to a method of improving the fluidic flow through a membrane mesh structure for the transportation of bodily fluids from a point of sampling to a point of measurement.

A method and apparatus () for obtaining a sample of blood. An embodiment includes an apparatus () which integrates lancing (), 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 ().

A method and apparatus () for obtaining a sample of blood. An embodiment includes of an apparatus () which integrates lancing (), 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 ().

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.

A method and apparatus for obtaining a sample of blood. An embodiment consists of an apparatus which integrates lancing, 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.

Method and apparatus for lancet launching device intergrated onto a blood-sampling cartridge

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 miniatuized and/or disposable.

Method and apparatus for improving success rate of blood yield from a fingerstick

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.

Blood sampling apparatus and method

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.

Cassette of lancet cartridges for sampling blood

An apparatus and method for pumping and optionally mixing of small quantities of biological fluid wherein the pumping mechanism is segregated from the biological fluid being pumped. The micro-pump pushes the biological fluid by compressing a cartridge housing the blood and reagents with collapsible walls with a roller or ball bearing, synchronized perpendicular plungers, or an acutely-angled member to push the biological fluid by collapsing the walls of the cartridge in the direction of flow.

Fluidically isolated pumping and metered fluid delivery system and methods

An apparatus and method for making a microscopic paddle wheel coupled inductively by an external electromagnet and used for valving and active pumping so that the actual pumping mechanism is completely isolated from the electromagnetic driver. The paddle wheel is inexpensive to manufacture and disposable. A cartridge having a network of conduits and reservoirs contains several of such paddle wheels to transport blood and reagents. A point-of-care device houses the electromagnetic driving mechanism and is reused with successive cartridges since the paddle wheels are contained by the cartridge and do not contaminate the driving mechanism.

Micro paddle wheel pump for precise pumping, mixing, dispensing, and valving of blood and reagents

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.
