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.
Claims30
A tissue compression device comprising:
- a base comprising a major surface configured to engage a dorsal surface of a hand of a patient, the hand being connected to an arm of the patient, the base comprising:
- a first lip extending from the major surface and configured to engage an ulnar border of the hand when the dorsal surface of the hand is engaged with the base;
- and
- a second lip extending from the major surface and configured to engage a radial border of the hand when the dorsal surface of the hand is engaged with the base:
- a flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand and at least one of a wrist or a forearm of the arm when the dorsal surface of the hand is engaged with the base, the wrist being proximal to the hand and the forearm being proximal to the wrist;
- and
- an expandable member mechanically connected to the flexible backing, wherein the expandable member is configured to be positioned over an ulnar region of the patient when the palmar surface of the hand and the at least one of the wrist or the forearm are engaged with the flexible backing and the dorsal surface of the hand is engaged with the base, the ulnar region being proximal to the hand, and wherein the expandable member is configured to apply pressure to the ulnar region.

A tissue compression device comprising:
- a rigid base comprising:
- a major surface configured to engage a dorsal surface of a hand of a patient;
- a radial lip extending from the major surface and configured to engage a radial border of the hand when the dorsal surface of the hand is engaged with the base;
- and
- an ulnar lip extending from the major surface and configured to engage an ulnar border of the hand when the dorsal surface of the hand is engaged with the base;
- an inextensible flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand to urge the dorsal surface of the hand toward the major surface of the base;
- and
- an expandable member mechanically connected to the flexible backing, wherein 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, and wherein the expandable member is configured to inflate to increase a volume of the expandable member.

A method comprising:
- mechanically connecting a flexible backing of a tissue compression device to a first base attachment structure of a plurality of base attachment structures defined by or extending from a major surface of a base of the tissue compression device, wherein the major surface is configured to engage a dorsal surface of a hand of a patient;
- and
- mechanically connecting the flexible backing to a second base attachment structure of the plurality of base attachment structures,
- wherein the flexible backing is configured to be adjustably mechanically connected to the base, wherein the tissue compression device further comprises an expandable member mechanically connected to the flexible backing, wherein the expandable member is configured to be positioned over an ulnar region of the patient when the dorsal surface of the hand is engaged with the major surface of the base, wherein the expandable member is configured to apply pressure to tissue near an ulnar artery of the patient, and wherein the base comprises:
- a first lip extending from the major surface and configured to engage an ulnar border of the hand when the dorsal surface of the hand is engaged with the base;
- and
- a second lip extending from the major surface and configured to engage a radial border of the hand when the dorsal surface of the hand is engaged with the base.
