Abstract

The apparatus and method for hemostasis that informs the provider as to whether the appropriate magnitude of pressure is being applied to a puncture site on a patient. A visual pulse indicator can visually convey whether or not there is proper blood flow at the puncture site based on the pulsing motion encountered by the visual pulse indicator on the puncture site. The visual pulse indicator can potentially factor in a variety of different input parameters in displaying information that is useful to providers.

Claims

1. A method of performing hemostasis on a puncture site on a patient, comprising:

positioning a visual pulse indicator relative to the puncture site of the patient;

viewing an indication from the visual pulse indicator, wherein the indication is associated with a blood flow attribute relating to the patient; and

selectively adjusting a pressure magnitude over the puncture site, wherein the selective adjustment is influenced by the blood flow attribute indicated by the visual pulse indicator.

2. The method of claim 1, wherein the hemostasis is performed as part of a transradial catheterization on the patient.

3. The method of claim 1, wherein the blood flow attribute detected by the visual pulse indicator is a pulsing motion on the puncture site.

4. The method of claim 3, wherein the visual pulse indicator is a reflective foil.

5. The method of claim 3, wherein the visual pulse indicator includes two Moiré

line patterns.

6. The method of claim 1, further comprising setting a timer component for signaling a future point in time in which the pressure magnitude is to be adjusted.

7. An apparatus for use over a puncture site for a patient during hemostasis, comprising:

a visual pulse indicator that provides for being positioned relative to the puncture site, wherein said visual pulse indicator provides for displaying a plurality of indications that relate to a plurality of blood flow attributes;

said plurality of indications including a first indication and a second indication;

said plurality of blood flow attributes including a constricted blood flow and a non-constricted blood flow;

wherein said first indication is displayed in conjunction with said constricted blood flow and wherein said second indication is displayed in conjunction with said non-constricted blood flow.

8. The apparatus of claim 7, wherein said visual pulse indicator is a reflective foil that provides for moving up and down along with the pulse of the patient, and wherein the hemostasis is performed as part of a transradial catheterization on the patient.

9. The apparatus of claim 8, wherein said reflective foil is comprised of a polyester.

10. The apparatus of claim 7, said apparatus further comprising a pressure component that provides for applying pressure to the puncture site and a body component, wherein said pressure component is a substantially transparent balloon attached to said visual pulse indicator, wherein said body component is a band, wherein said substantially transparent balloon is movable along said band, and wherein said substantially transparent balloon provides for being removed from said band.

11. The apparatus of claim 7, said apparatus further comprising a bottom surface coated with an anti-adhesion component.

12. The apparatus of claim 7, said apparatus further comprising a timing component that provides for conveying a duration after which pressure on the puncture site is to be adjusted.

13. The apparatus of claim 7, wherein said pressure component is a balloon, wherein said balloon is substantially transparent, wherein said visual pulse indicator is integrated with said balloon, and wherein said visual pulse indicator provides for being integral to a surface on said balloon that is in direct contact with the patient.

14. The apparatus of claim 13, wherein said bottom surface of said balloon is thicker at a center portion of said balloon than at a side portion of said balloon.

15. The apparatus of claim 13, said apparatus further comprising a centering member positioned on said bottom surface of said balloon to enhance the sensitivity of said visual pulse indicator.

16. The apparatus of claim 13, said apparatus further comprising a band, wherein said balloon provides for being temporarily secured to said band, and wherein said balloon includes a plurality of slide openings that provide for the movement of said balloon along said band.

17. An apparatus for use over a puncture site for a patient during hemostasis, comprising:

a visual pulse indicator that provides for the display of a blood flow attribute relating to the puncture site;

a body component, wherein said visual pulse indicator is attached to said body component; and

a balloon, wherein said balloon is attached to said body component, wherein the inflation of said balloon provides for increasing the pressure on the puncture site, wherein the hemostasis is performed as part of a transradial catheterization on the arm of the patient.

18. The apparatus of claim 17, further comprising at least one of:

(a) a timing component attached on said body component;

(b) an anti-adhesion component positioned on a bottom surface of said apparatus; and

(c) a center member on a bottom surface of said balloon for enhancing the sensitivity of said visual pulse indicator.

19. The apparatus of claim 17, wherein said balloon is substantially transparent, wherein said balloon provides for being permanently fixed to said body component, said apparatus further comprising a foam pad that is not permanently fixed to said body component.

20. The apparatus of claim 17, wherein said body component is a substantially transparent band, wherein said band includes a first end and a second end, said apparatus further comprising a fabric fastening tape comprised of a dense arrangement of tiny nylon hooks and an interlocking nylon pile, wherein said fabric fastening tape is attached to said first end and to said second end, said band including a timing component, said apparatus further including a non-stick coating on a bottom surface of said apparatus and a center member on said bottom surface of said apparatus.
