Abstract

Tissue compression devices having a tension limiting strap retainer and methods of using the same. The tissue compression devices described herein may include a strap retainer that is attached to a base by an elastic member that is configured to draw the strap retainer towards the base. The tissue compression devices described herein may also include a tension indicator that extends between the base of the tissue compression device and strap retainer. The tension indicator may be configured to limit the travel distance of the strap retainer away from the base in response to forces acting on the strap retainer. The tension indicator may also provide visual feedback to a user of the tension force in a strap to attach the tissue compression device to a patient.

First claim

What is claimed is:

1. A method of attaching a tissue compression device to a patient, the method comprising:
positioning a base of a tissue compression device such that a pressure apparatus attached to the base is located over selected tissue at a selected location, wherein the base comprises a first side and a strap retainer attached to a second side of the base, wherein the strap retainer is attached to the second side of the base by an elastic member, and wherein a tension indicator extends between the base and the strap retainer;
connecting a free end of a strap to the strap retainer, wherein a fixed end of the strap is attached to the base, and wherein the strap and the base are configured to encircle a limb when the free end of the strap is connected to the strap retainer;
stretching the elastic member by moving the strap retainer away from the base, wherein the stretching elongates the elastic member so that the strap retainer is moved from a retracted position to an extended position, and wherein the elastic member applies a tension force on the strap through the strap retainer when the strap retainer is in the extended position, wherein the tension indicator prevents movement of the strap retainer away from the base past a selected distance when stretching the elastic member by moving the strap retainer away from the base.

2. A method according to claim 1 , wherein the method comprises providing a visual indication of the tension force applied to the strap using the tension indicator extending between the base and the strap retainer.

3. A method according to claim 1 , wherein the elastic member provides a selected tension force when it is stretched so that the strap retainer is at the selected distance from the base.

4. A method according to claim 1 , wherein the tension indicator is attached to the strap retainer.

5. A method according to claim 4 , wherein the tension indicator comprises a structural stop that mechanically interferes with a slot in the base when the strap retainer reaches the selected distance.

6. A method of attaching a tissue compression device to a patient, the method comprising:
positioning a base of a tissue compression device such that a pressure apparatus attached to the base is located over selected tissue at a selected location, wherein the base comprises a first side and a strap retainer attached to a second side of the base, wherein the strap retainer is attached to the second side of the base by an elastic member, and wherein a tension indicator extends between the base and the strap retainer;
connecting a free end of a strap to the strap retainer, wherein a fixed end of the strap is attached to the base, and wherein the strap and the base are configured to encircle a limb when the free end of the strap is connected to the strap retainer;
moving the strap retainer away from the base, wherein the moving stretches the elastic member and wherein the tension indicator prevents movement of the strap retainer away from the base past a selected distance; and
providing a visual indication of a tension force applied to the strap using the tension indicator, wherein the tension indicator is separate and discrete from the elastic member.

7. The method of claim 6 , wherein the tension indicator comprises an inextensible member.

8. The method of claim 6 , wherein the moving the strap retainer away from the base comprises moving the strap retainer from a retracted position to an extended position.

9. The method of claim 8 , wherein the elastic member applies the tension force on the strap through the strap retainer when the strap retainer is fixed in the extended position.

10. A method according to claim 6 , wherein the elastic member provides a selected tension force to the strap when it is stretched so that the strap retainer is at the selected distance from the base.

11. A method according to claim 6 , wherein the tension indicator is attached to the strap retainer.

12. A method according to claim 11 , wherein the tension indicator comprises a structural stop that mechanically interferes with a slot in the base in which the tension indicator moves when moving the strap retainer away from the base.
