Tissue compression device with tension limiting strap retainer
First Claim
1. A tissue compression device comprising:
- a pressure apparatus attached to a base, the pressure apparatus configured to apply pressure to selected tissue at a selected location located beneath the compression device;
a strap comprising a first end attached to a first side of the base and a second end distal from the first end;
an elastic member having first and second ends, the first end of the elastic member is attached to a second side of the base opposite from the first side of the base;
a strap retainer attached to the second end of the elastic member, such that the elastic member extends between the second side of the base and the strap retainer, wherein the elastic member is configured to be extensible in response to tension forces while the elastic member draws the strap retainer towards the second side of the base, and wherein the strap retainer is configured to retain the second end of the strap such that the strap and strap retainer retain the base and the pressure apparatus over the selected location when the second end of the strap is retained by the strap retainer;
a tension indicator comprising an inextensible member extending between the base and the strap retainer, wherein the tension indicator is configured to provide visual indication of a tension force supplied between the strap retainer and the base by the elastic member;
wherein the tension indicator is configured to limit a travel distance to a selected travel distance between the strap retainer and the second side of the base when the strap is tightened to retain the base and the pressure apparatus over the selected location.

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.
