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 (40)

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

a visual pulse indicator that is configured to be positioned on the patient near the puncture site, wherein said visual pulse indicator provides for displaying a plurality of indications that relate to a plurality of blood flow attributes, wherein said visual pulse indicator is a reflective foil that provides for moving up and down along with a pulse of said patient, said reflective foil having a first side and a second side, said first side configured to be placed facing the patient's skin near the puncture site; and

a pressure component configured to apply pressure to said puncture site, wherein said pressure component is a substantially transparent balloon, and wherein said pressure component is attached to one of said first side and said second side of said reflective foil;

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 reflective foil visually shows the moving up and down along with the pulse of the patient.

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

3. The apparatus of claim 1 , wherein said reflective foil is comprised of a polyester.

4. The apparatus of claim 1 , said apparatus further comprising a body component, 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.

5. The apparatus of claim 1 , said apparatus further comprising a timing component that provides for conveying a duration after which pressure on the puncture site is to be adjusted.

6. The apparatus of claim 1 , wherein said visual pulse indicator provides a visual indication of a physical pulsing motion of an artery near the puncture site.

7. The apparatus of claim 1 , wherein said visual pulse indicator is configured to be arranged at or downstream of the puncture site.

8. The apparatus of claim 1 , wherein said visual pulse indicator has a moire line pattern.

9. The apparatus of claim 1 , wherein said first side of said reflective foil is configured to be placed in direct contact with the patient's skin.

10. The apparatus of claim 1 , said apparatus further comprising a bottom surface coated with an anti-adhesion component.

11. The apparatus of claim 10 , wherein the anti-adhesion component is a silicone coating.

12. The apparatus of claim 1 , wherein said visual pulse indicator is integrated with said balloon.

13. The apparatus of claim 12 , wherein a surface of said balloon that is attached to said reflective foil is thicker at a center portion of said balloon than at a side portion of said balloon.

14. The apparatus of claim 12 , said apparatus further comprising a centering member positioned on a surface of said balloon that is attached to said reflective foil to enhance the sensitivity of said visual pulse indicator.

15. The apparatus of claim 12 , 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.

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

a visual pulse indicator that is configured to display a blood flow attribute relating to the puncture site, wherein said visual pulse indicator is a reflective foil that provides for moving up and down along with a pulse of said patient, said reflective foil having a first side and a second side, said first side configured to be placed facing the patient's skin near the puncture site,

wherein said reflective foil visually shows the moving up and down with the pulse of said patient:

a body component, wherein said visual pulse indicator is attached to said body component, the body component is configured to position the visual pulse indicator on the patient; and

a substantially transparent balloon, wherein said balloon is attached to said body component, wherein the inflation of said balloon provides for increasing a pressure on the puncture site, wherein said balloon is attached to one of said first side and said second side of said reflective foil.

17. The apparatus of claim 16 , 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.

18. The apparatus of claim 16 , 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.

19. The apparatus of claim 16 , 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.

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

a visual pulse indicator that is configured to display a blood flow attribute relating to the puncture site;

wherein said visual pulse indicator is a reflective foil that provides for moving up and down along with a pulse of said patient;

a body component, wherein said visual pulse indicator is attached to said body component, and said body component is configured to position said visual pulse indicator on the patient downstream from said puncture site; and

a balloon, wherein said balloon is attached to said body component and said visual pulse indicator, wherein the inflation of said balloon provides for increasing the pressure at the puncture site, wherein said visual pulse indicator is integrated with said balloon.

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

a visual pulse indicator that is configured to be positioned on the patient near the puncture site, wherein said visual pulse indicator provides for displaying a plurality of indications that relate to a plurality of blood flow attributes, wherein said visual pulse indicator is a reflective foil that provides for moving up and down along with a pulse of said patient, said reflective foil having a first side and a second side, said first side configured to be placed facing the patient's skin near the puncture site; and

a pressure component configured to apply pressure to said puncture site, wherein said pressure component is a substantially transparent balloon, and wherein said pressure component is attached to one of said first side and said second side of said reflective foil;

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 non-constricted blood flow;

wherein said first side of said reflective foil is configured to be placed in direct contact with the patient's skin.
