Abstract

In accordance with a first aspect, a noninvasive apparatus comprises a housing (42) having a grasping region (44), and a noninvasive extraction device (10) to noninvasively extract a sample from a hand of an end user at the grasping region (44). In accordance with a second aspect, a noninvasive apparatus comprises a card-shaped housing which supports the noninvasive extraction device 10. In accordance with a third aspect, a retaining member (22) retains a removable biosensor (16) proximate to at least a portion of the noninvasive extraction device (10).

Claims

1. An apparatus which cooperates with a removable biosensor, the apparatus comprising:

a noninvasive extraction device to noninvasively extract a biological sample;

a retaining member to retain the removable biosensor proximate to at least a portion of the noninvasive extraction device, the retaining member to cover a first portion of a surface of the removable biosensor while exposing a second portion of the surface of the removable biosensor for user contact, the removable biosensor to sense a characteristic of the biological sample;

a first set of at least two electrodes to couple to the removable biosensor near a first edge of the removable biosensor covered by the retaining member; and

a second set of at least two electrodes to couple to the removable biosensor near a second edge of the removable biosensor covered by the retaining member.

2. The apparatus of claim 1 wherein the first portion comprises a peripheral portion of the surface of the removable biosensor.

3. The apparatus of claim 2 wherein the second portion comprises a central portion of the surface of the removable biosensor.

4. The apparatus of claim 1 wherein the noninvasive extraction device includes an ultrasonic emitter.

5. The apparatus of claim 1 wherein the removable biosensor covers at least a portion of the noninvasive extraction device when retained by the retaining member.

6. The apparatus of claim 1 further comprising a third set of at least two electrodes to couple to the removable biosensor near a third edge of the removable biosensor covered by the retaining member.

7. The apparatus of claim 1 further comprising a card-shaped housing supporting the noninvasive extraction device and the retaining member.

8. The apparatus of claim 1 further comprising:

an interface; and

a processor to receive a program from an external device via the interface, the processor to direct the noninvasive extraction device and to process data from the biosensor in accordance with the program.

9. An apparatus which cooperates with a removable biosensor, the apparatus comprising:

a card-shaped housing having a length of about 85.6 mm and a width of about 54 mm;

a noninvasive extraction device supported by the card-shaped housing to noninvasively extract a biological sample;

a retaining member to retain the removable biosensor proximate to at least a portion of the noninvasive extraction device, the retaining member to cover a first portion of a surface of the removable biosensor while exposing a second portion of the surface of the removable biosensor for user contact, the removable biosensor to sense a characteristic of the biological sample;

a first set of at least two electrodes to couple to the removable biosensor near a first edge of the removable biosensor covered by the retaining member; and

a second set of at least two electrodes to couple to the removable biosensor near a second edge of the removable biosensor covered by the retaining member.
