Abstract

An apparatus for storing and dispensing a test strip includes a container configured to store a stack of test strips. The container maintains appropriate environmental conditions, such as humidity, for storing the test strips. An engaging member is disposed in the container and is adapted to contact one test strip of the stack of test strips. An actuator actuates the engaging member to dispense the one test strip from the container. Since one test strip is dispensed at a time, the remaining test strips are not handled by the user. Accordingly, the unused test strips remain free of contaminants such as naturally occurring oils on the user'"'"'s hand.

Claims

1. An apparatus for storing and dispensing test strips, comprising:

a container configured to store a stack of test strips;

a spring disposed in the container, the spring adapted to contact one test strip of the stack of test strips;

an actuator for actuating the spring to dispense the one test strip from the container, wherein the actuator comprises a lever arm that pivots about a pivot point, a first end of the lever being exposed outside the container for direct manipulation by a user, and a second end of the lever arm being directly connected to the spring to drive the spring so that pivoting of the lever causes the spring to dispense the contacted test; and

a cartridge, insertable into the container, and to which the lever arm is pivotably connected, wherein the pivot point is disposed on the cartridge.

2. The apparatus of claim 1, further comprising a lid hingedly connected to the container to selectively open and close the container.

3. The apparatus of claim 1, wherein the cartridge comprises a guide track that slidably guides movement of the spring.

4. The apparatus of claim 1, further comprising a biasing element for urging the stack of test strips into a position such that the spring contacts an edge of one test strip of the stack of test strips.

5. The apparatus of claim 3, further comprising a biasing element for urging the stack of test strips into a position against a wall of the cartridge such that the spring contacts and edge of one test strip of the stack of test strips.

10. The apparatus of claim 3, wherein the guide track has a curved portion corresponding to a path of an end of the lever arm.

11. The apparatus of claim 3, wherein the guide track has a curved portion along which an end of the lever arm travels.

6. An apparatus for storing and dispensing test strips, comprising:

a container for storing a stack of test strips;

a spring for contacting one test strip of the stack of test strips, the spring contacting an edge of one test strip of the stack of test strips;

an actuator for actuating the spring to dispense the contacted test strip, wherein the actuator comprises a lever arm that pivots about a pivot point, a first end of the lever being exposed outside the container for direct manipulation by a user, and a second end of the lever arm being directly connected to the spring to drive the spring so that pivoting of the lever causes the spring to dispense the contacted test strip; and

cartridge, insertable into the container, and to which the lever arm is pivotably connected, the cartridge comprising a guide track that slidably guides movement of the spring, wherein the guide track has a curved portion along which an end of the lever arm travels.

7. The apparatus of claim 6, further comprising a lid hingedly connected to the container to selectively open and close the container.

8. The apparatus of claim 6, further comprising a biasing element for urging the stack of test strips into a position such that the spring contacts one test strip of the stack of test strips.

9. The apparatus of claim 6, further comprising a biasing element for urging the stack of test strips into a position against a wall of the cartridge such that the spring contacts one test strip of the stack of test strips.

12. The apparatus of claim 6, further comprising a cartridge, insertable into the container, and to which the lever arm is pivotably connected, wherein the pivot point is disposed on the cartridge.
