摘要:
A portable medical analyzer comprising a sampling module with a sample port for receiving body fluid, an assay sensor module for analysis of the body fluid, an analytical detector module with detection of information from the assay, and a communications module for transferring the information to a remote location via a wired or wireless network.
摘要:
These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes an electrically powered drive force generator. A penetrating member is operatively coupled to the force generator. The force generator moves the member along a path out of a housing having a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. An analyte detecting member is positioned to receive fluid from a wound created by the penetrating member. The detection member is configured to determine a concentration of an analyte in the fluid using a sample of less than 1 mL of the fluid. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
摘要:
A body fluid sampling system for use on a tissue site has a housing and a penetrating member driver at least partially within the housing. At least one disposable is within the housing. The disposable includes an analyte sensor in a sample chamber that is configured to receive body fluid from a wound in tissue created by a penetrating member. A penetrating member is associated with the sample chamber. Each penetrating member and its associated sample chamber have a combined occupied volume of no more than about 5.0 cm3.

A skin penetrating system has a housing member and a plurality of penetrating members positioned in the housing member. A tissue stabilizing device is coupled to the housing member. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
摘要:
A body fluid sampling system is provided for use on a tissue site. In one embodiment, the system comprises a cartridge; a penetrating member driver; a plurality of penetrating members arranged in a radial configuration on the cartridge wherein sharpened distal tips of the penetrating members point radially outward; wherein an active one of the penetrating members may be operatively coupled to the penetrating member driver, the penetrating member driver moving the active one along a path out of a housing having a penetrating member exit, into the tissue site, stopping in the tissue site, and withdrawing out of the tissue site; and a plurality of analyte detecting members, wherein at least one of the analyte detecting members is positioned to receive fluid from a wound created by the active one of the penetrating members, wherein the detecting members are not pierced by the active one of the penetrating members.
摘要:
A method of controlling a penetrating member is provided. The method comprises providing a lancing device comprising a penetrating member driver having a position sensor and a processor that can determine the relative position and velocity of the penetrating member based on measuring relative position of the penetrating member with respect to time; providing a predetermined velocity control trajectory based on a model of the driver and a model of tissue to be contacted. In some embodiments, a feedforward control to maintain penetrating member velocity along said trajectory.
