Abstract

This disclosure provides equipment and processes for blood glucose management. Embodiments may comprise a lancet device that includes a base that supports a lancet and a cover. The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position. In another aspect, a biological test kit may include a reusable module and a disposable module. The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.

Claims

1. A biological test kit comprising:

(a) a reusable module comprising (i) a reusable module housing with top, bottom, front, back, and lateral surfaces, (ii) measuring equipment supported by the reusable module housing and configured to measure a property of a biological sample, and (iii) a reusable module connector supported by at least one of the front, back, or lateral surfaces of the reusable module housing; and

(b) a disposable module comprising (i) a disposable module housing with top, bottom, front, back, and lateral surfaces, (ii) first and second lancet stations each having a base that is supported by the bottom surface of the disposable module housing and comprising a lancet supported by and stationary with respect to the base and extending toward the top surface of the disposable module housing at an angle of approximately 90°

relative to the bottom surface of the disposable module housing, along with a lancet cover that is movable between an un-depressed position in which the lancet cover covers the lancet and a depressed position in which the lancet protrudes through an aperture in the lancet cover, the first lancet station being configured to facilitate generation of a first biological sample, and the second lancet station being configured to facilitate generation of a second biological sample, (iii) first and second strip stations each supported by the disposable module housing, the first strip station and including a first biological strip configured to receive the first biological sample and to provide the first biological sample to the measuring equipment for measurement of the property, and the second strip station including a second biological strip configured to receive the second biological sample and to provide the second biological sample to the measuring equipment for measurement of the property, and (iv) a disposable module connector supported by at least one of the front, back, or lateral surfaces of the disposable module housing and being modularly connectible to the reusable module connector.

2. The biological test kit of claim 1, wherein the disposable module housing comprises (A) a first sub-module housing that supports the first lancet station and includes a first sub-module connector and (B) a second sub-module housing that supports the first strip station and includes a second sub-module connector that is modularly connectible to the first sub-module connector.

3. The biological test kit of claim 1, wherein the disposable module connector and the reusable module connector together comprise an interlocking fastener.

4. The biological test kit of claim 1, wherein the first strip station includes a slot in the disposable module housing and a strip container positioned in the slot, the strip container being configured to slide into and out of the slot between a closed position and an open position and being adapted to provide access to the first biological strip when in the open position.

5. The biological test kit of claim 1, wherein the first strip station comprises:

a recess defined in the disposable module housing configured to hold the first biological strip, and

a strip station cover removably connected to the disposable module housing, the strip station cover being configured to cover the recess and prevent access to the first biological strip when in a covered position and to permit access to the first biological strip when in an uncovered position.

6. The biological test kit of claim 1,

wherein the measuring equipment comprises a correlation mechanism configured to identify a measured biological sample as having originated from the first strip station or the second strip station.

7. The biological test kit of claim 6, wherein the measuring equipment is configured to provide whether the measured biological sample originated from the first strip station or the second strip station to the display monitor for display.

8. The biological test kit of claim 1, wherein the biological test kit has an overall thickness of less than one centimeter.

9. The biological test kit of claim 1, wherein the reusable module further comprises (iv) a display monitor supported by the reusable module housing and configured to display the measured property.

10. The biological test kit of claim 1, wherein the reusable module further comprises (iv) a wireless transmitter supported by the reusable module housing and configured to transmit a signal representative of the measured property to a separate device for display.

11. The biological test kit of claim 1, wherein the reusable module further comprises (iv) a mobile device case connector supported by the reusable module housing and configured to detachably connect the reusable module to a mobile device case.

12. The biological test kit of claim 1, wherein the disposable module further comprises (iv) an insulin delivery device connector supported by the disposable module and configured to detachably connect the disposable module to an insulin delivery device.

13. The biological test kit of claim 1, wherein the biological test kit has a rectangular shape.
