摘要:
A device and method for measuring clotting times in a fluid, typically blood, within a microchannel, with the onset of clotting being determined by measurement of the rate of change, or the value, of capacitance or impedance between two electrodes situated on either side of the microchannel. The device includes an upper support member and a lower support member with a microchannel formed therein. The device also includes electrodes situated along the length of the microchannel.

An improved disposable glucose test strip for use in a test meter of the type which receives a disposable test strip and a sample of blood from a patient and performs an electrochemical analysis is made using a non-conductive integrated reagent/blood separation layer containing a filler, an enzyme effective to oxidize glucose, e.g., glucose oxidase, and a mediator effective to transfer electrons from the enzyme. The integrated layer formulation is printed over a conductive carbon element to form a working electrode. The filler, for example a silica filler, is selected to have a balance of hydrophobicity and hydrophilicty such that one drying it forms a two-dimensional network on the surface of the conductive element. The response of this test strip is essentially temperature independent over relevant temperature ranges and is substantially insensitive to the hematocrit of the patient.

A method for determining an analyte concentration in blood is described that reduces the effects of hematocrit using a test strip attached to a test meter. The test strip includes a working electrode and a reference electrode. The test meter applies a test voltage between the working electrode and the reference electrode. After a user applies a blood sample containing an analyte onto the test strip, the test meter measures a plurality of test currents for a test time interval.

An actuation system for a bodily fluid extraction device includes a detector cap, at least one vibration sensor connected to the detector cap, and at least one signal processing unit in communication with the vibration sensor. In addition, the signal processing unit is configured to receive an output signal from the vibration sensor, analyse the received output signal, and to send an actuation signal to the bodily fluid extraction device based on the analysis of the received output signal.

A lancing device includes a housing, a lancing mechanism disposed at least partially within the housing and configured to lance a target site with a lancet, and an integrated light source. The integrated light source, in combination with the housing, produces an intense beam of light for illumination and a diffuse light that provides a user with spatial awareness.

A device for promoting the expression of bodily fluid from a target site on a user's body includes a base and a pressure application mechanism. The pressure application mechanism is attached to the base and urges bodily fluid toward the target site. The pressure application mechanism configured for urging the bodily fluid by sequentially increasing an area of contact and applied pressure between the pressure application mechanism and the user's body in the vicinity of the target site. Moreover, the area of contact and applied pressure sequentially increases in a direction toward the target site.

A lancing kit includes a lancing device and a lancing device cap. The cap for the lancing device includes a cap body and at least one sensor. In addition, the cap body includes a distal end with a target site contact surface, a proximal end for attachment to a lancing device and an opening through the cap body from the distal end to the proximal end. Furthermore, at least a portion of the target site contact surface is moveable between a first position and a second position upon application of a predetermined pressure to that portion of the distal end contact surface, and the sensor is configured to detect movement of the portion of the distal end contact surface into the second position and communicate such detection to the lancing device.
