Patent ID: 8668656

Claim:
A body fluid sampling device for use on a patient, comprising: a cartridge; at least one penetrating member positioned in the cartridge; a controllable penetrating member driver configured to be coupled to the at least one penetrating member; a processor coupled to the controllable penetrating member and providing a controllable velocity of the at least one penetrating member; a sample port for receiving a body fluid in response to a puncturing event by the at least one penetrating member; a sample chamber; a channel coupled to the sample port and the sample chamber, at least a portion of the channel being a capillary channel with a hydrophilic surface positioned adjacent to the sample chamber; at least one electrode positioned in the sample chamber and configured to determine an amount of an analyte in the body fluid; and a mesh membrane positioned in the channel and at the sample port or adjacent to the sample port to guide a flow of the body fluid through at least a portion of the capillary channel with the mesh providing that the body fluid contacts the channel regardless of an orientation of body fluid sampling device, the mesh membrane and channel configured to provide a transport of the body fluid to the sample chamber and a measurement in less than 10 seconds.
