Abstract

A method for manufacturing a diagnostic test strip is disclosed according to one embodiment. The method includes the acts of providing an application sheet having a plurality of adhesive dots thereon, providing a first substrate layer having at least one feature located thereon, and providing a second substrate layer. The method further including the acts of transferring at least one of the plurality of adhesive dots located on the application sheet to the first substrate layer, aligning the first substrate layer with the second substrate layer, and attaching the first substrate layer and the second substrate layer using the transferred adhesive dots, wherein the attaching of the first and second substrate layers is performed without any additional alignment.

Claims

1. A method for manufacturing a test strip comprising the acts of providing an application sheet having a first surface;

printing a plurality of adhesive dots on the first surface of the application sheet;

providing a plurality of substrate layers having at least one face;

fashioning at least one feature onto a first of the plurality of substrate layers, applying the application sheet to the first substrate layer, the adhesive dots being located between the first surface of the application sheet and the first substrate layer;

transferring at least one adhesive dot by removing the application sheet from the first substrate layer;

aligning a second of the plurality of substrate layers with the first substrate layer; and

applying the second substrate layer to the first substrate layer, such that the transferred adhesive dots are in contact with both the first substrate layer and the second substrate layer.

2. The method of claim 1 further comprising the act of applying a silicon coating to the first surface of the application sheet prior to printing the plurality of adhesive dots on the first surface of the application sheet.

3. The method of claim 1, wherein the act of fashioning at least one feature is performed by punching the first substrate layer.

4. The method of claim 1, wherein the act of fashioning at least one feature is performed by embossing the first substrate layer.

5. The method of claim 1, wherein the act of printing a plurality of adhesive dots on the first surface of the application sheet occurs after the fashioning of at least one feature onto the first substrate layer.

6. The method of claim 1, wherein the plurality of adhesive dots is printed with glue.

7. The method of claim 1, wherein the manufactured test strip is an electrochemical test strip.

8. The method of claim 1, wherein the manufactured test strip is an optical test strip.

9. A method for manufacturing a test strip comprising the acts of providing an application sheet having a first surface;

applying an adhesive to a plurality of different areas on the first surface of the application sheet;

providing a plurality of substrate layers adapted to form the test strip, the plurality of substrate layers having at least one face;

fashioning at least one feature into a first of the plurality of substrate layers, wherein the at least one feature creates an uppermost surface and a lowermost surface on the face of the first substrate layer;

applying the application sheet to the first substrate layer, the adhesive being located between the first surface of the application sheet and the face of the first substrate layer, at least one of the plurality of different areas of the adhesive being in contact with the uppermost surface of the face of the first substrate layer;

transferring the adhesive by removing the application sheet from the first substrate layer after at least one of the plurality of different areas of the adhesive is in contact with the uppermost surface of the face of the first substrate layer, such that the adhesive in contact with the uppermost surface of the face of the first substrate layer remains;

aligning a second of the plurality of substrate layers with the first substrate layer; and

applying the second substrate layer to the first substrate layer, the adhesive remaining on the uppermost surface of the face of the first substrate layer being in contact with both the first substrate layer and the second substrate layer.

10. The method of claim 9, wherein the act of applying an adhesive to the plurality of different areas on the first surface of the application sheet is performed by printing the adhesive onto the first surface of the application sheet.

11. The method of claim 9 further comprising the act of applying a silicon coating to the first surface of the application sheet prior to applying the adhesive to the plurality of different areas on the first surface of the application sheet.

12. The method of claim 9, wherein the adhesive applied to the first surface of the application sheet is glue.
