Abstract

The present disclosure relates to a test strip handling device (100) that includes a housing (110) having an interior compartment (112) in which the test strips are received and stored. The device (100) facilitates sanitary handling and disposal of the test strips.

Claims

1. A test strip handling device, comprising:

a housing having an external opening;

an interior compartment disposed within the housing, the interior compartment having a space configured to store at least one test strip, the at least one test strip including a reagent adapted to react with an analyte in a fluid sample and to produce a reaction indicative of the concentration of the analyte in the fluid sample;

first and second members positioned adjacent one another within the housing, and

an energy storage device including a third member frictionally engaged with one of the first and second members and configured to rotate in a first direction to store energy and to bias the first and second members to move relative to one another upon release of the stored energy,

wherein the first and second members are constructed and arranged to receive the at least one test strip there between and to guide the at least one test strip from the opening into the space of the interior compartment.

2. The device of claim 1, wherein when the at least one test strip is stored within the interior compartment, the first and second members inhibit removal of the at least one test strip through the opening.

3. The device of claim 1, wherein the first member is a first roller and the second member is a second roller.

4. The device of claim 3, wherein the first roller has a generally cylindrical configuration and has a first axis extending lengthwise and the second roller has a generally cylindrical configuration and has a second axis extending lengthwise, the first axis and the second axis being generally parallel with respect to each other.

5. The device of claim 3, wherein the first and second rollers are rotatable relative to one another, and wherein the first and second rollers are configured to cause translation of the at least one test strip when the at least one test strip is positioned between the first and second rollers.

6. The device of claim 5, wherein the first roller is in contact with the second roller.

7. The device of claim 5, wherein the first roller and the second roller are spaced apart from one another, such that a gap is created there between, the gap sized to receive a test strip therein.

8. The device of claim 5, wherein counter-clockwise rotation of the first roller and clockwise rotation of the second roller causes translation of the at least one test strip in a direction toward the space of the inner compartment when the at least one test strip is positioned between the first and second rollers.

9. The device of claim 3, wherein the energy storage device is configured to bias the first and second rollers to rotate relative to one another.

10. The device of claim 9, wherein the third member is a third roller and the energy storage device further includes:

a spring; and

a locking mechanism transitionable between a locked state and an unlocked state,

wherein rotation of the third roller in the first direction causes the spring to wind and store potential energy, and

wherein when the locking mechanism is in the locked state, the spring is prevented from unwinding, and when the locking mechanism is in the unlocked state, the spring unwinds to convert the potential energy to kinetic energy which causes the first and second rollers to rotate relative to one another.

11. The device of claim 10, wherein the locking mechanism includes a pinion operatively coupled to at least one of the first and second rollers, and a rack configured to engage the pinion when in the locked state and to be disengaged from the pinion when in the unlocked state.

12. The device of claim 3, further comprising:

an actuator configured to cause rotation of the first and second rollers relative to one another.

13. The device of claim 1, further comprising:

a guide channel configured to receive the at least one test strip therethrough in a direction toward the space of the interior compartment.

14. A test strip handling device, comprising:

a housing;

an interior compartment disposed within the housing, the interior compartment having a space configured to store at least one test strip, the at least one test strip including a reagent adapted to react with an analyte in a fluid sample and to produce a reaction indicative of the concentration of the analyte in the fluid sample; and

first and second rollers positioned adjacent one another within the housing and capable of rotating relative to one another,

an energy storage device including a third roller frictionally engaged with one of the first and second rollers and configured to rotate in a first direction to store energy and to bias the first and second rollers to rotate relative to one another upon release of the stored energy,

wherein when the at least one test strip is positioned adjacent the first and second rollers, counter-clockwise rotation of the first roller and clockwise rotation of the second roller causes translation of the at least one test strip in a direction toward the space of the interior compartment.

15. The device of claim 14, wherein the first roller has a generally cylindrical configuration and has a first axis extending lengthwise and the second roller has a generally cylindrical configuration and has a second axis extending lengthwise, the first axis and the second axis being generally parallel with respect to each other.

16. The device of claim 15, wherein the first roller is in contact with the second roller.

17. The device of claim 15, wherein the first roller and the second roller are spaced apart from one another, such that a gap is created there between, the gap sized to receive the test strip therein.

18. The device of claim 15, wherein the energy storage device further includes:

a spring; and

a locking mechanism transitionable between a locked state and an unlocked state,

wherein rotation of the third roller in the first direction causes the spring to wind and store potential energy, and

wherein when the locking mechanism is in the locked state, the spring is prevented from unwinding, and when the locking mechanism is in the unlocked state, the spring unwinds to convert the potential energy to kinetic energy which causes the first and second rollers to rotate relative to one another.

19. A method of storing a test strip, comprising:

placing an end of the test strip into an opening of a test strip handling device, the test strip including a reagent adapted to react with an analyte in a fluid sample and to produce a reaction indicative of the concentration of analyte in the fluid sample;

positioning the test strip at the junction between first and second rollers housed within the test strip handling device, such that the test strip is positioned adjacent the first and second rollers;

rotating a third roller to store energy to be used to cause the first and second rollers to rotate upon actuation;

actuating the first roller to rotate in a first direction and the second roller to rotate in a second direction, wherein the second direction is opposite the first direction; and

drawing the test strip into an interior compartment of the test strip handling device while the first and second rollers are rotating.

20. The method of claim 19, wherein the step of rotating occurs before the step of placing.
