Abstract
Abstract The invention relates to a device for sampling and analyzing blood. It comprises an auto-pricker (1), a magazine (2) for strips, these strips comprising a reactive zone, and a reflectometer (6). Moreover, the magazine (2) is integral with the auto-pricker (1) and the device comprises means (7, 8) enabling the reflectometer (6) and the auto-pricker (1) to be made integral at rest.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
192 words
A device for sampling blood and evaluating desired concentrations of substances therein, comprising: an auto-pricker; a plurality of strips, said strips including a reactive area having a color which varies according to the concentration of the substance being evaluated; a reflectometer comprising: (a) reading system means for supplying information about said reactive area; (b) processing system means for receiving and processing said information supplied by said reading system means, said processing system means comprising microprocessor and read-only memory means for converting said information supplied by said reading system into the desired concentration; and (c) display system means for directly displaying the desired concentration; and magazine means for holding said strips, said magazine means being integral with said auto-pricker and having holder means for receiving one of said strips externally of said reflectometer before said one of said strips has received the sampled blood; said auto-pricker being separable from said reflectometer during pricking, and said auto-pricker and said reflectometer including first integration means for integrating said auto-pricker and said reflectometer when at rest and second integration means for integrating said auto-pricker and said reflectometer during reading of the color of said reactive area.
Claim 2
Independent Claim
192 words
A device for sampling blood and evaluating desired concentrations of substances therein, comprising: an auto-pricker; a plurality of strips, said strips including a reactive area having a color which varies according to the concentration of the substance being evaluated; a reflectometer comprising: (a) reading system means for supplying information about said reactive area; (b) processing system means for receiving and processing said information supplied by said reading system means, said processing system means comprising microprocessor and read-only memory means for converting said information supplied by said reading system into the desired concentration; and (c) display system means for directly displaying the desired concentration; and magazine means for holding said strips, said magazine means being integral with said auto-pricker and having holder means for receiving one of said strips externally of said reflectometer before said one of said strips has received the sampled blood; said auto-pricker being separable from said reflectometer during pricking, and said auto-pricker and said reflectometer including first integration means for integrating said auto-pricker and said reflectometer when at rest and second integration means for integrating said auto-pricker and said reflectometer during reading of the color of said reactive area.
Claim 3
Dependent Claim
29 words
The device of claim 1, wherein said second integration means comprises complementary means for nesting said auto-pricker in said reflectometer during reading of the color of said reactive area.
Claim 4
Dependent Claim
37 words
The device of claim 1, wherein said auto-pricker and said reflectometer include tensioning means for triggering said reflectometer only when said auto-pricker and said reflectometer are made integral during reading of the color of said reactive area.
Claim 5
Dependent Claim
23 words
The device of claim 1, wherein said magazine means includes a disposable plug incorporating desiccator means for absorbing moisture to conserve said strips.
Claim 6
Dependent Claim
86 words
The device of claim 1, wherein said magazine means comprises a disposable plug provided with first groove means for receiving one of said strips before said one of said strips has received the sampled blood, wherein said plug includes clip means for carrying said first groove means, and wherein said reflectometer includes second groove means for receiving said clip means and positioning said reactive area of said one of said strips relative to said reading system means of said reflectometer when said reflectometer is in use.
Claim 7
Dependent Claim
17 words
The device of claim 1, said reflectometer further comprising: (d) a stopwatch and (e) a sonic device.
Claim 8
Dependent Claim
29 words
The device of claim 4, wherein said plug includes planar face means for resting said device when said device is at rest and when said reflectometer is being used.
Claim 9
Independent Claim
176 words
A device for sampling blood and evaluating desired concentrations of substances therein, comprising: an auto-pricker; a plurality of strips, said strips including a reactive area having a color which varies according to the concentration of the substance being evaluated; a reflectometer comprising: (a) reading system means for supplying information about said reactive area; (b) processing system means for receiving and processing said information supplied by said reading system means, said processing system means comprising microprocessor and read-only memory means for converting said information supply by said reading system into the desired concentration; and (c) display system means for directly displaying the desired concentration; and magazine means for holding said strips, said magazine means being integral with said auto-pricker and including a disposable plug provided with groove means for receiving one of said strips externally of said reflectometer before said one of said strips has received the sampled blood; said auto-pricker and said reflectometer including integration means for integrating said auto-pricker and said reflectometer when at rest and during reading of the color of said reactive area.
Claim 10
Independent Claim
176 words
A device for sampling blood and evaluating desired concentrations of substances therein, comprising: an auto-pricker; a plurality of strips, said strips including a reactive area having a color which varies according to the concentration of the substance being evaluated; a reflectometer comprising: (a) reading system means for supplying information about said reactive area; (b) processing system means for receiving and processing said information supplied by said reading system means, said processing system means comprising microprocessor and read-only memory means for converting said information supply by said reading system into the desired concentration; and (c) display system means for directly displaying the desired concentration; and magazine means for holding said strips, said magazine means being integral with said auto-pricker and including a disposable plug provided with groove means for receiving one of said strips externally of said reflectometer before said one of said strips has received the sampled blood; said auto-pricker and said reflectometer including integration means for integrating said auto-pricker and said reflectometer when at rest and during reading of the color of said reactive area.
