  • a user When using self monitoring blood glucose meters it is convenient for many users to be sitting at a table, for example. It is particularly desirable for a user to be able to apply a sample of blood to a strip 10 with the meter 2 on a tabletop or similar flat surface. Also, even when not at a table it is important that the fill indicator window on the strip be visible at the same time as the result on the display. It is therefore of importance that a strip 10 be presented in a "flat" position with the first major surface of strip 10 substantially parallel with the first major surface of meter 2. A user may thus be able to view fill indicator window 22 at the same time as visual display 6. During the process of sample application a user may thus be able to follow any "on screen" instructions while applying blood from a finger.

  • the casing 4 of meter 2 when compared with a prior art meter e.g. OneTouch® Ultra, will have enlarged external and internal dimensions in order to accommodate the stack of strips or the cassette or vial used to contain the stack of strips 24.
  • one of the most compact strip orientations to use in a meter to keep the meter size small is a stack.
  • a stack is typically elongate and rectangular and this can dictate the shape of the meter. Nevertheless on dispensing of a strip 10 from a stack of strips 24, the uppermost strip 10 exits the rectangular meter 2 on one of the minor elongate sides of the meter 2.
  • the display 18 is on one of the major sides of the meter 2 and it can therefore be difficult for a user to orientate the meter 2 appropriately to apply a sample of blood from a finger.

Thereby facilitating a user of such a device to make a measurement of blood glucose with an associated strip or test sensor 10, with minimum inconvenience.
  • a stack of strips 24 is provided within outer casing 4, dispensing a strip 10 through delivery port 8 from stack 24 would present the strip with its first major surface perpendicular to first major surface of outer casing 4.

  • Cam track 1014 has a gradient profile between cam follower test stop 1043 and cam follower end stop 1045 that causes a net axial movement of approximately 3 mm of slide block assembly 1008 within rotary barrel 1004.
  • a used test sensor 1040 is expelled from rotatable PC 1001 when slide block assembly 1008 is driven forward towards test sensor port 1003.
  • the movement of cam follower 1010 along cam track 1014 between cam follower test stop 1043 towards cam follower end stop 1045 causes slide block assembly 1008 to move within rotary barrel 1004.

  • First drive cog 1044 and second drive cog 1060 rotate within first drive cog mount 1066 and second drive cog mount 1068 respectively.
  • Second drive cog 1060 comprises two gears with a major and minor diameter. The major diameter interacts with drive shaft 1056 and the minor diameter interacts with first drive cog 1044.
  • First drive cog 1044 interacts with rear cover 1018.

  • a series of conductive tracks extend from elongate portion 1028 and terminate at a series of vias 1024 within flexible circuit assembly 1020.
  • the ends of signal terminals 1006 extend beyond rear cover 1018, protruding through separate vias 1024.
  • Electrical connections are formed between separate conductive tracks (not shown) on flexible circuit assembly 1020 and the ends of signal terminals 1006 at the junction with separate vias 1024.
  • positional nails 1016 protrude through separate vias 1024 in flexible circuit assembly 1020.
  • Electrical connections are also formed between positional nails 1016 with separate conductive tracks (not shown) on flexible circuit assembly 1024.
  • Elongate member thus provides a means to bridge the main circuits of the meter 2 with signal terminals 1006 and positional nails 1016.
  • elongate member 1028 is provided to overcome the fact that rear cover 1018 rotates through an arc of about 135 degrees when rotary barrel 1004 is driven from "load” position, past “test” position, to “eject” position.
  • the flexibility of elongate portion 1028 thus maintains the integrity of the electrical connections between a test sensor 1040 and the meter circuits during the process of making a test measurement.
