Abstract

A blood glucose test device with viewing lens seal includes a meter body rigid portion of a first polymeric material and an opening. A resilient portion of a second polymeric material more compressible than the first polymeric material integrally connected to the rigid portion defines a rigid portion outer covering. A resilient portion edge extends beyond the rigid portion and partially into the opening about a perimeter of the opening. A transparent polymeric material lens has an outer perimeter surface in contact with the resilient portion edge. Multiple flexible arms extending from the lens each have a hook member. Each hook member engages a receiving member positioned in a meter body and is retained by multiple backup ribs. Hook member engagement at a locking position pulls the lens toward the edge partially compressing the second polymeric material and creating a fluid seal between the perimeter surface and edge.

Claims

1. A blood glucose test device having a viewing lens seal, comprising:

a blood glucose test meter body, having;

a rigid portion of a first polymeric material and having an opening;

a resilient portion of a second polymeric material more compressible than the first polymeric material, the resilient portion integrally connected to the rigid portion and defining an outer covering of the rigid portion; and

an edge of the resilient portion extending beyond the rigid portion and partially into the opening about substantially all of a perimeter of the opening;

a lens of a transparent polymeric material having an outer perimeter surface in contact with the edge of the resilient portion; and

multiple flexible arms integrally connected to the lens, each arm having a hook member, the hook member engaging a receiving member positioned in each of multiple receiving apertures created in the meter body, engagement of each hook member with one of the receiving members at a locking position operating to pull the lens toward the edge partially compressing the second polymeric material and thereby creating a fluid seal between the perimeter surface and the edge.

2. The blood glucose test device having a viewing lens seal of claim 1, wherein the edge includes an angular surface defining a complementary angle with an angle of the perimeter surface of the lens.

3. The blood glucose test device having a viewing lens seal of claim 1, wherein the lens includes an aperture receiving a data display screen of the medical test meter when the second polymeric material is partially compressed.

4. The blood glucose test device having a viewing lens seal of claim 1, wherein the resilient portion further defines an outer perimeter surface of the meter body.

5. The blood glucose test device having a viewing lens seal of claim 1, further including a data display board providing a digital display of the results of a test conducted by a processor, the data display board being visible through a data display section of the lens.

6. The blood glucose test device having a viewing lens seal of claim 1, wherein the lens includes a front facing area of the meter body defining a function selection section separated from a data display section of the meter body.

7. The blood glucose test device having a viewing lens seal of claim 1, wherein the resilient portion includes a web integrally extending from the edge of the resilient portion which deflects when in contact with the outer perimeter surface of the lens.

8. The blood glucose test device having a viewing lens seal of claim 1, wherein each of the flexible arms includes a beam elastically deflected in an outward deflection direction during installation of the lens onto the edge.

9. The blood glucose test device having a viewing lens seal of claim 1, further including:

a processor connected to a circuit board, the circuit board connected to the rigid portion;

a data display providing a digital display of the results of a test conducted by the processor; and

a frame, the frame connected to the data display and sandwiching the rigid portion.

10. The blood glucose test device having a viewing lens seal of claim 9, further including:

a second body portion connected to the rigid portion having the circuit board positioned between the second body portion and the rigid portion; and

a battery powering the glucose test meter connected to the second body portion.

11. A blood glucose test device having a viewing lens seal, comprising:

a blood glucose test meter including;

a meter body having;

a first body portion of a first substantially rigid polymeric material having an opening;

a second body portion connected to the first body portion;

a circuit board having a processor and a test strip receiving member mounted thereto, the circuit board positioned between the first body portion and the second body portion;

a resilient body portion of a second polymeric material more compressible than the first polymeric material integrally connected to the first body portion and defining an outer perimeter covering for the first body portion; and

an edge of the resilient body portion extending beyond the first body portion and partially into the opening;

a lens of a transparent polymeric material positioned at the opening of the meter body, the lens having an outer perimeter surface in direct contact with the edge resilient body portion edge such that the lens substantially covers the opening; and

multiple flexible arms integrally connected to the lens each having a hook member, the hook member engaging a receiving member in each of multiple receiving apertures created in the meter body, engagement of each hook member with one of the receiving members at a locking position operating to partially compress the second polymeric material at the edge thereby creating a fluid seal between the perimeter surface and the edge.

12. The blood glucose test device having a viewing lens seal of claim 11, wherein each of the flexible arms includes a flexible beam displaced into one of the receiving apertures in an installation direction.

13. The blood glucose test device having a viewing lens seal of claim 12, wherein the hook member is connected to the flexible arm, the hook contacting a tapered surface created on an outer wing of a panel portion of the first body portion to thereby deflect the flexible arm.

14. The blood glucose test device having a viewing lens seal of claim 13, wherein the hook member slides along the tapered surface to elastically deflect the flexible arm in an outward deflection direction until the hook member extends past a maximum extension point of the outer wing, the hook member thereafter rebounding in a return direction.

15. The blood glucose test device having a viewing lens seal of claim 13, further including a backup rib integrally connected to the first body portion and directed toward the hook member, wherein after rebounding in the return direction, a coupling surface of the hook member contacts an engagement surface of the outer wing and the backup rib is positioned proximate to the hook member opposite to the coupling surface preventing release of the lens.

16. The blood glucose test device having a viewing lens seal of claim 11, further including a web integrally extending from the edge of the resilient portion, the web deflected when contacted by the outer perimeter surface of the lens.

17. The blood glucose test device having a viewing lens seal of claim 11, wherein the lens has a continuous curving convex shaped outer surface.

18. The blood glucose test device having a viewing lens seal of claim 11, wherein substantially all of the perimeter surface of the lens directly contacts the edge of the resilient portion and partially compresses the resilient material of the resilient body portion to create the fluid seal.

19. The blood glucose test device having a viewing lens seal of claim 11, wherein a portion of the perimeter surface of the lens directly contacts the edge of the resilient body portion and partially compresses the resilient material of the resilient body portion to create the fluid seal.

20. The blood glucose test device having a viewing lens seal of claim 11, wherein the lens includes a concave area providing access to an inlet port of the meter body aligned with the test strip receiving member to slidably receive the test strip.
