Abstract

A packaged medical device includes upper and lower flexible sheets, a lance body and a test strip. The lance body includes upper and lower surfaces, an opening that extends between the upper and lower surfaces and a dermal tissue penetration member that projects into the lance body opening. The test strip has an opening therethrough and is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening. The upper flexible sheet is attached to the lance body upper surface and covers the lance body opening, while the lower flexible sheet is detachably attached to the test strip and covers the test strip opening. The upper flexible sheet, lance body and test strip are configured such that, when the lower flexible sheet has been detached to uncover the test strip opening, the upper flexible sheet, lance body and test strip can be bent to deploy the dermal tissue penetration member from the lance body opening. A kit includes the packaged medical device described above and a deployment device for detaching the lower flexible sheet and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member. A method for deploying a dermal tissue penetration member of a packed medical device includes providing the packaged medical device described above, detaching the lower flexible sheet to uncover the test strip opening and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member.

Claims

1. A packaged medical device comprising:

an upper flexible sheet;

a lance body that includes;

a lance body upper surface;

a lance body lower surface;

a lance body opening extending from the lance body upper surface to the lance body lower surface; and

a dermal tissue penetration member projecting into the lance body opening;

a test strip with a test strip opening therethrough; and

a lower flexible sheet, wherein;

the upper flexible sheet is attached to the lance body upper surface covering the lance body opening;

the test strip is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening;

the lower flexible sheet is detachably attached to the test strip covering the test strip opening; and

the upper flexible sheet, lance body and test strip are configured such that, when the lower flexible sheet has been at least partially detached from the test strip, thereby uncovering the test strip opening, the upper flexible sheet, lance body and test strip can be bent to deploy the dermal tissue penetration member from the lance body opening.

2. The packaged medical device of claim 1, wherein the test strip is an electrochemical test strip.

3. The packaged medical device of claim 1, wherein the test strip is a colorimetric test strip.

4. The packaged medical device of claim 1, wherein the test strip is a glucose measurement test strip.

5. The packaged medical device of claim 1, wherein the upper flexible sheet, lance body and test strip can be bent through an arc in the range of approximately 90 degrees to approximately 100 degrees to deploy the dermal tissue penetration member.

6. The packaged medical device of claim 1, wherein the packaged medical device is formed using lamination techniques.

7. The packaged medical device of claim 1, wherein the test strip includes at least one electrode contact and the upper flexible sheet is attached to the lance body upper surface and the test strip is attached to the lance body lower surface such that the at least one electrode contact extends beyond the lance body and the upper flexible sheet.

8. A kit comprising:

a packaged medical device that includes;

an upper flexible sheet;

a lance body that includes;

a lance body upper surface;

a lance body lower surface;

a lance body opening extending from the lance body upper surface to the lance body lower surface; and

a dermal tissue penetration member projecting into the lance body opening;

a test strip with a test strip opening therethrough; and

a lower flexible sheet,

wherein;

the upper flexible sheet is attached to the lance body upper surface covering the lance body opening;

the test strip is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening;

the lower flexible sheet is detachable attached to the test strip covering the test strip opening; and

the upper flexible sheet, lance body, and test strip are configured such that, when the lower flexible sheet has been at least partially detached from the test strip, thereby uncovering the test strip opening, the upper flexible sheet, lance body and test strip-can be bent to deploy the dermal tissue penetration member from the lance body opening; and

a deploying device configured for at least partially detaching the lower flexible sheet from the test strip and bending of the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member from the lance body opening.

9. The kit of claim 8, wherein the deploying device includes:

a detaching block for at least partially detaching the lower flexible sheet from the test strip; and

a bending block for bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member.

10. The kit of claim 8, wherein the test strip is an electrochemical test strip.

11. The kit of claim 8, wherein the test strip is a colorimetric test strip.

12. The kit if claim 8, wherein the test strip is a glucose measurement test strip.

13. The kit of claim 8, wherein the packaged medical device is a laminated packaged medical device.

14. A method for deploying a dermal tissue penetration member of a packaged medical device, the method comprising:

providing a packaged medical device, wherein;

the packaged medical device includes

an upper flexible sheet;

a lance body that includes;

a lance body upper surface;

a lance body lower surface;

a lance body opening extending from the lance body upper surface to the lance body lower surface; and

a dermal tissue penetration member projecting into the lance body opening;

a test strip with a test strip opening therethrough; and

a lower flexible sheet,

wherein;

the upper flexible sheet is attached to the lance body upper surface covering the lance body opening;

the test strip is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening;

the lower flexible sheet is detachably attached to the test strip covering the test strip opening; and

the upper flexible sheet, lance body, and test strip are configured such that, when the lower flexible sheet has been at least partially detached from the test strip such the test strip opening is uncovered, the upper flexible sheet, lance body and test strip can be bent to deploy the dermal tissue penetration member from the lance body opening;

detaching, at least partially, the lower flexible sheet from the test strip to uncover the test strip opening using the deployment device; and

bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member from the lance body opening.

15. The method of claim 14, wherein the detaching and deploying steps are accomplished using a deployment device.

16. The method of claim 15, wherein the detaching and deploying steps are accomplished using a deployment device that includes a stripping block and a folding block.

17. The method of claim 14, wherein the detaching and deploying steps are accomplished manually by a user.
