Abstract

In some examples, a tissue compression device configured to apply pressure at the snuffbox includes a flexible backing adjustably mechanically connected to a base, and an expandable member mechanically connected to the flexible backing. The base includes a major surface configured to engage a palmar surface of a hand of a patient, for example, to position the hand of the patient in a predetermined configuration, and a plurality of base attachment structures extending from the major surface. The flexible backing is adjustably mechanically connected to the base via the plurality of base attachment structures. The expandable member is configured to be positioned over the snuffbox of the hand of the patient and apply pressure to tissue at the snuffbox when the palmar surface of the hand is engaged with the major surface of the base.

First claim

What is claimed is:

1. A tissue compression device comprising:
a base comprising:
a major surface configured to engage a palmar surface of a hand of a patient; and
a plurality of base attachment structures extending from the major surface;

a flexible backing adjustably mechanically connected to the plurality of base attachment structures; and
an expandable member mechanically connected to the flexible backing, wherein the expandable member is configured to be positioned over a snuffbox of the hand of the patient when the palmar surface of the hand is engaged with the major surface of the base, and wherein the expandable member is configured to apply pressure to tissue at the snuffbox.

2. The tissue compression device of claim 1 , wherein the expandable member comprises a bladder configured to inflate to at least a pressure to cause patent hemostasis of a vascular access site at the snuffbox.

3. The tissue compression device of claim 1 , wherein the expandable member comprises a transparent polymer.

4. The tissue compression device of claim 1 , wherein the flexible backing comprises a plurality of backing attachment structures, and wherein each respective backing attachment structure of the plurality of backing attachment structures is configured to adjustably secure the flexible backing to a respective base attachment structure of the plurality of base attachment structures.

5. The tissue compression device of claim 1 , wherein at least one base attachment structure of the plurality of base attachment structures is continuous with the major surface.

6. The tissue compression device of claim 1 , wherein at least one base attachment structure of the plurality of base attachment structures is physically separate from and attached to the major surface.

7. The tissue compression device of claim 1 , wherein at least one base attachment structure of the plurality of base attachment structures extends away from the major surface in a direction parallel to or transverse to the major surface.

8. The tissue compression device of claim 1 , wherein the flexible backing comprises a substantially inextensible material.

9. The tissue compression device of claim 1 , wherein at least one of the base or the flexible backing is configured to engage a left hand of the patient, a right hand of the patient, or both the left hand and right hand of the patient.

10. The tissue compression device of claim 1 , wherein the base comprises a substantially rigid thermoplastic or a substantially rigid thermoset plastic.

11. The tissue compression device of claim 1 , wherein the base comprises one or more support structures configured to reduce a range of motion of a digit of the hand or a portion of a wrist of the patient when the palmar surface of the hand is engaged with the major surface of the base.

12. The tissue compression device of claim 1 , wherein the base is configured to position the hand of the patient in a predetermined configuration when the palmar surface of the hand is engaged with the major surface of the base.

13. The tissue compression device of claim 12 , wherein the predetermined configuration is a grasped position.

14. The tissue compression device of claim 1 , wherein the base comprises a pad configured to engage the palmar surface of the hand of the patient to position the hand of the patient in a predetermined configuration when the palmar surface of the hand is engaged with the major surface.

15. The tissue compression device of claim 1 , wherein the expandable member is configured to be detached and subsequently reattached to the flexible backing.

16. A tissue compression device comprising:
a base comprising a substantially rigid material, wherein the base comprises:
a major surface configured to engage a palmar surface of a hand of a patient to position the hand of the patient in a predetermined configuration; and
a plurality of base attachment structures extending from the major surface; a flexible backing comprising a substantially inextensible material, the flexible backing being adjustably mechanically connected to the base via the plurality of base attachment structures; and
an expandable member mechanically connected to the flexible backing, wherein the expandable member is configured to be positioned over a snuffbox of a hand of a patient when the palmar surface of the hand is engaged with the major surface of the base, and wherein the expandable member is configured to inflate to apply pressure to selected tissue at the snuffbox.

17. The tissue compression device of claim 16 , wherein, when the palmar surface of the hand is engaged with the major surface of the base, the predetermined configuration is a grasped position.

18. The tissue compression device of claim 16 , wherein the expandable member is configured to be detached and subsequently reattached to the flexible backing.

19. 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 extending from a major surface of a base of the tissue compression device, wherein the major surface is configured to engage a palmar 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 a snuffbox of the hand of the patient when the palmar surface of the hand is engaged with the major surface of the base, and wherein the expandable member is configured to apply pressure to selected tissue at the snuffbox.

20. The method of claim 19 , further comprising positioning the palmar surface of the hand of the patient on the major surface of the base.

21. The method of claim 20 , further comprising, after positioning the palmar surface of the hand of the patient on the major surface of the base, inflating the expandable member to cause patent hemostasis of a vascular access site at the snuffbox.

22. The method of claim 20 , further comprising, after positioning the palmar surface of the hand of the patient on the major surface of the base, adjusting a position of the expandable member relative to the hand of the patient.

23. The method of claim 19 , wherein the flexible backing comprises a plurality of backing attachment structures, wherein mechanically connecting the flexible backing to the first base attachment structure comprises adjustably mechanically connecting a first backing attachment structure of the plurality of backing attachment structures to the first base attachment structure of the plurality of base attachment structures, and wherein mechanically connecting the flexible backing to the second base attachment structure comprises adjustably mechanically connecting a second backing attachment structure of the plurality of backing attachment structures to the second base attachment structure of the plurality of base attachment structures.
