## Background
BACKGROUND
Analyte meters are typically used for the measurement of an analyte in a sample. More particularly they are often used for the detection of the concentration of glucose within blood. For example, a diabetic may be required to use a glucose meter several times a day times a day in order to monitor the glucose levels within their blood. The diabetic user is often required to carry the meter, a lancet device for effecting a wound large enough to sample blood from, as well as diagnostic test strips on their person as they perform their daily routines to ensure that they can perform a blood glucose measurement at any given time. In order to facilitate the ease of carrying these items it is desirable to make them small, so that they can fit in an enclosure that is easily maneuverable (such as a purse). Further the devices should be user-friendly and easy to use.

In another embodiment of the present invention, the analyte measurement device has an overall pen-shape. For example, as illustrated in FIG. 2, the housing 203 of the device 201 is generally annular and terminates at a first end 215 and at a second end 217 opposite the first end 215 of the housing 203. The generally annular housing 203 also has a central axis 202 extending through both the first 215 and second ends of the housing 203. The axis of rotation of the user interface is not limited and for example it may be at an oblique angle with respect to a central axis of the housing.
In FIG. 2, the rotatable user interface 211 is rotatably connected to the housing 203 at the first end 215 of the housing 203 and the test strip opening 209 is disposed at the second end 217 of the housing 203. The axis of rotation of the rotatable user interface 211 is along the central axis 202 of the housing 203.
In another embodiment, as depicted in FIG. 3, the rotatable user interface 311 is rotatably connected to the housing 303 between the first 315 and second 317 ends of the housing 303 and the test strip opening 309 is disposed at the second end 317 of the housing 303. As shown in FIG. 3, the axis of rotation 313 of the rotatable user interface 311 is perpendicular to the central axis 302 of the housing 303.
The rotatable user interface may be rotated completely around the axis of rotation or it may be restrained from moving completely around the axis of rotation. In one embodiment the rotatable user interface is throttled so that as it is turned further away from an original position the information or options displayed on the screen is scrolled through at a faster pace.
The analyte meter is integrated into the housing and includes a display, a test strip interface, and a processor programmed to calculate and to store in the hierarchy of information the concentration of an analyte, preferably glucose, in a blood sample applied to a test strip received in the test strip interface. The housing has an opening for receiving the meter display as well as an opening for receiving a diagnostic test strip inserted into the test strip interface of the analyte monitoring meter. The analyte meter of the present invention is not limited and is preferably that described in US patent publication number US 2005/0265094, herein incorporated by reference.
The processor of the meter is also programmed to display a hierarchy of information or options having a plurality of levels to a user. As shown in FIG. 4, each level (402, 403, 404, 405) of the plurality of levels of the hierarchy 401 comprises information or options selected from the group consisting of: a selectable lower level (406, 407, 408, 409, 410, 411, 412, 413), a selectable upper level (414, 415, 416), a selectable subroutine performable by the processor (417, 418, 420, 421), and a selectable parameter (422, 423, 424). As a user rotates the rotatable user interface around the axis of rotation, the display scrolls through selectable information or options contained in the open level. For example if the first level is open the user may scroll through selectable information or options comprising: Information A 406, Information B 407, Subroutine A 417, and Subroutine B 418. When a user translates the rotatable user interface along its axis of rotation one of the selectable information levels or options therein contained 406, 407, 417, 418 is selected.
FIG. 5A illustrates an exemplary configuration of the hierarchy 501 of a meter in accordance with the present invention. In a first level, the hierarchy has selectable lower levels comprising selectable alarm options, selectable past test data, and selectable meter option information. The first level also has a selectable “perform-test” subroutine, and a selectable “turn-meter-off” subroutine. Each of these selectable lower levels and selectable subroutines options will be discussed below.
Selectable Alarm Information:
If a user selects this lower level from the first level in the hierarchy (i.e. by scrolling to the selectable alarm information option and translating the rotatable user interface along the axis of rotation) a second level of information or options is displayed. The second level comprises three options including an open a higher level option and two open lower level options. The open a higher level option, if selected, will open the first level. The two selectable lower levels comprise options for the user to set a time alarm or to set a measured glucose level alarm.
If a user selects the set a time alarm yet another lower level of selectable information or options will be displayed that comprises selectable parameters options for the user to select a time, or times, of the day that the alarm will sound. Such an alarm could be used to alert a user that a time has come for the user to test a sample.
If a user selects the set a glucose level alarm another lower level of selectable information or options will be display comprising selectable parameter options for the user to select a glucose level at which an alarm will sound if the level is exceeded in a subsequent diagnostic test. Such an alarm could be used to alert a user that the analyte measured in a sample has exceeded a preset value. For example, in the event that the analyte measured is glucose, the alarm could alert a user if a hypo/hyper glycemic level has been reached or if such a level is about to be reached.
Selectable Past Test Data Information:
If a user selects this option from the first level a second level of information or options appears on the display. In FIG. 5A, the second level comprises three options including an open a higher level option and three open lower level options. The open a higher level option, if selected, will open the first level as described above. The three lower levels comprise options for the user to select how the previous test data will be displayed (i.e. past 24 hours, past 48 hours, past week, and past month). Depending on what the user selects, the data will be displayed accordingly. An optional subroutine is provided in the test data under the past 24 hour results that illustrates that the processor may be programmed to display results in graphical format.
Selectable Meter Options Information:
If a user selects this option from the first level of information or options, a second level of information or options appears on the display. In FIG. 5A, the second level comprises various meter settings that a user is able to change, a meter calibration subroutine, and a go back to the first level option. Examples of changeable meter setting options are global date and time settings and optional hierarchy of information settings that allows a user to change what information is contained and displayed in the hierarchy.
Selectable “Perform-Test” Subroutine:
If a user selects this option from the first level, the processor will perform, and store data related to, a diagnostic test on a sample applied to a test strip received within the housing to determine the concentration of an analyte therein contained.
Selectable “Turn-Meter-Off” Subroutine:
If a user selects this option from the first level, the processor is programmed to and will shut the meter off.
FIG. 5B illustrates yet another exemplary configuration of the hierarchy of information or options 5001 of a meter in accordance with the present invention. In a first level of information or options, the hierarchy has selectable lower levels of information or options comprising (1) a view the most recent test result selection, (2) a review meal time averages selection, (3) a review weekly averages selection, (4) a projected result selection, (5) a set time selection, (6) a set date selection, (7) a set an alarm selection, (8) a set the meter volume selection, and (9) a test a sample selection. As illustrated by the vertical lines in FIG. 5B, a user may scroll through the selectable lower levels of information (1) through (9), contained in the first level of information by rotating the user interface. After user selects one of the selectable lower levels of information or options the user may scroll through that level by again rotating the user interface.
