Abstract

A multiple-use blotting device for blotting blood from a fingertip includes a substrate, and a blood absorbing pad secured to the substrate. The blood absorbing pad has a plurality of blood absorbing sections that are evenly spaced from one another. The blotting device includes a protective cover overlying the blood absorbing pad, the protective cover having a window formed therein for exposing the blood absorbing pad. The cover is coupled with the substrate and is adapted to rotate relative to the substrate and the blood absorbing pad for sequentially aligning the window of the cover with each of the blood absorbing sections for exposing, one at a time, each of the blood absorbing sections. After one section of the pad has been used to blot blood, the cover is rotated for exposing a clean, unused section of the pad, while covering the used, blood-soaked section of the pad.

Claims

1. A multiple-use blotting device for blotting blood from a fingertip comprising:

a substrate;

a blood absorbing pad secured atop said substrate, said blood absorbing pad having a plurality of blood absorbing sections, wherein said substrate comprises a top surface and said blood absorbing pad is secured to the top surface of said substrate;

a cover overlying said blood absorbing pad, said cover having at least one window formed therein for exposing one of said blood absorbing sections, wherein said cover is moveable relative to said blood absorbing pad for exposing a fresh section of said blood absorbing pad through said at least one window while covering a previously used section of said blood absorbing pad.

2. The multiple-use blotting device as claimed in claim 1, wherein said at least one window comprises a single window formed in said cover for exposing one of said blood absorbing sections, wherein said cover is rotatable relative to said blood absorbing pad for exposing only one of said blood absorbing sections at a time while covering the remaining blood absorbing sections of said blood absorbing pad.

3. The multiple-use blotting device as claimed in claim 2, wherein said blood absorbing sections are spaced from one another on said blood absorbing pad.

4. The multiple-use blotting device as claimed in claim 3, wherein said blood absorbing sections are evenly spaced from one another around a perimeter of said blood absorbing pad.

5. The multiple-use blotting device as claimed in claim 2, wherein said cover has a circular shape, and wherein said window extends between a center of said cover and an outer perimeter of said cover.

6. The multiple-use blotting device as claimed in claim 2, wherein said cover comprises:

a shell having said window formed therein; and

a knob provided on a top surface of said shell, wherein said knob is engageable for rotating said shell for sequentially aligning said window with each of said blood absorbing sections.

7. The multiple-use device as claimed in claim 6, further comprising a shaft extending through said blood absorbing pad, said shaft having an upper end coupled with said shell and a lower end coupled with said substrate.

8. The multiple-use device as claimed in claim 7, wherein said cover, said knob and said shaft rotate simultaneously with one another, and wherein said cover, said knob and said shaft are rotated relative to said blood absorbing pad and said substrate.

9. The multiple-use device as claimed in claim 1, wherein said cover and said substrate comprise polymer materials and said blood absorbing pad comprises cotton or fiber.

10. The multiple-use blotting device as claimed in claim 1, wherein said blood absorbing pad has a top surface accessible through said at least one window of said cover.

11. The multiple-use blotting device as claimed in claim 1, wherein said blood absorbing pad has a porous cover.

12. The multiple-use blotting device as claimed in claim 1, wherein said blood absorbing pad comprises an antibacterial agent, a germicidal agent, a disinfectant, or a moisturizer.

13. The multiple-use blotting device as claimed in claim 2, wherein said substrate has a side wall that extends around a perimeter of said substrate and a plurality of projections that extend outwardly from said side wall, and wherein said cover has an inner surface having at least one projection adapted to engage said side wall projections of said substrate for generating an audible sound when said cover projection passes over one of said substrate projections.

14. A multiple-use blotting device for blotting blood from a fingertip comprising:

a substrate having a top surface;

a blood absorbing pad secured over the top surface of said substrate, said blood absorbing pad having a plurality of blood absorbing sections that are spaced from one another on said blood absorbing pad;

a protective cover overlying said blood absorbing pad, said protective cover having a plurality of windows formed therein that are associated with said plurality of blood absorbing sections of said blood absorbing pad, wherein said cover is coupled with said substrate and is adapted to move relative to said substrate and said blood absorbing pad for selectively aligning said windows with each of said blood absorbing sections, and wherein said protective cover comprises a shell having a knob provided at a top surface of said shell, and wherein said device further comprises a shaft used for forming a moveable connection between said shell and said substrate, said shaft having an upper end coupled with said shell and a lower end coupled with said substrate.

15. The multiple-use blotting device as claimed in claim 14, wherein said blood absorbing pad and said protective cover have circular shapes, wherein said protective cover is rotatable relative to said blood absorbing pad, and wherein said windows are located between a center of said protective cover and an outer perimeter of said protective cover.

16. The multiple-use blotting device as claimed in claim 14, wherein said protective cover includes a first inner window overlying an interior region of said blood absorbing pad, and a second intermediate window covering an intermediate region of said blood absorbing pad, and wherein said protective cover is rotatable in clockwise and counterclockwise directions for exposing, one at a time, each of said blood absorbing sections through said windows.

17. The multiple-use blotting device as claimed in claim 14, wherein said device has a diameter of about 3-5 inches and a thickness of about 0.10-1.00 inches.

18. A multiple-use blotting device for blotting blood from a fingertip comprising:

a substrate having a top surface;

a blood absorbing pad secured over the top surface of said substrate, said blood absorbing pad having a plurality of blood absorbing sections that are spaced from one another on said blood absorbing pad;

a protective cover overlying said blood absorbing pad, said protective cover having a plurality of windows formed therein that are associated with said plurality of blood absorbing sections of said blood absorbing pad;

at least one sliding element disposed between said protective cover and said blood absorbing pad, wherein said sliding element is retractable from a first position to a second position for exposing at least one of said blood absorbing sections through at least one of said windows, and wherein said sliding element is moveable from the second position back to the first position for recovering the at least one of said blood absorbing sections exposed through the at least one of said windows.
