Abstract

In some examples, a tissue compression device includes a base including a major surface configured to engage a dorsal surface of a hand of a patient, a flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand when the dorsal surface of the hand is engaged with the base, and an expandable member mechanically connected to the flexible backing. The expandable member is configured to be positioned over an ulnar region of the patient when the palmar surface of the hand is engaged with the flexible backing and the dorsal surface of the hand is engaged with the base, such that inflation of the expandable member may apply pressure to tissue near the ulnar artery of the patient.

First claim

What is claimed is:

1. A tissue compression device comprising:
a band configured to engage a wrist of a patient, the band comprising:
a base comprising at least one base attachment structure and a major surface configured to engage a first portion of the wrist of the patient; and
a flexible backing comprising at least one backing attachment structure and configured to engage a second portion of the wrist of the patient,
wherein the at least one backing attachment structure is configured to adjustably mechanically connect the flexible backing to the at least one base attachment structure;

a first expandable member directly mechanically connected to the flexible backing, wherein the first expandable member is configured to be positioned over an ulnar region of the patient when the band is engaged with the wrist of the patient, the first expandable member being configured to apply pressure to the ulnar region; and
a second expandable member directly mechanically connected to the flexible backing, wherein the second expandable member is configured to be positioned over a radial region of the patient when the band is engaged with the wrist of the patient, the second expandable member being configured to apply pressure to the radial region, and wherein the first expandable member and the second expandable member are connected to the same flexible backing.

2. The tissue compression device of claim 1 , wherein the first expandable member comprises a first bladder configured to inflate to at least a pressure to cause compression of tissue near an ulnar artery of the patient, and wherein the second expandable member comprises a second bladder configured to inflate to at least a pressure to cause patent hemostasis of a vascular access site at a radial artery of the patient.

3. The tissue compression device of claim 1 , wherein at least one of the first expandable member or the second expandable member is removably mechanically connected to the band.

4. The tissue compression device of claim 1 , wherein at least one of the first expandable member or the second expandable member is integrally formed with the band.

5. The tissue compression device of claim 1 , wherein the at least one backing attachment structure is configured to adjust a tension of the flexible backing to urge at least one of the first expandable member or the second expandable member toward the wrist of the patient when the wrist of the patient is engaged with the band.

6. The tissue compression device of claim 1 , wherein the base comprises a substantially rigid thermoplastic or a substantially rigid material and the flexible backing comprises a substantially inextensible material.

7. The tissue compression device of claim 1 , wherein the first portion of the wrist is different from the second portion of the wrist, and wherein the first portion and the second portion define an outer perimeter of the wrist.

8. The tissue compression device of claim 1 , wherein the base extends circumferentially from a first end to a second end, and wherein the flexible backing extends circumferentially from the first end of the base to the second end of the base.

9. The tissue compression device of claim 1 , wherein the at least one backing attachment structure is disposed at one end of the flexible backing and is separate from the first expandable member and the second expandable member along the length of the flexible backing.
