Pressure relief devices

Abstract

In one representative embodiment, a pressure relief device comprises a flexible, radially inelastic band having first and second end portions and a groove, wherein the groove is configured to interlock the first and second end portions of the band in a closed-loop configuration.

I claim: 
     
         1 . A pressure relief device, comprising a flexible, radially inelastic band having first and second end portions and a groove, wherein the groove is configured to interlock the first and second end portions of the band in a closed-loop configuration. 
     
     
         2 . The pressure relief device of  claim 1 , wherein the band comprises an inner core covered in a self-adherent fabric or material configured to retain the first and second end portions of the band in the closed-loop configuration when the first and second end portions radially overlap each other. 
     
     
         3 . The pressure relief device of  claim 1 , wherein the band comprises an attachment mechanism coupled to the band, and the attachment mechanism is configured to retain the first and second end portions of the band in the closed-loop configuration when the first and second end portions radially overlap each other. 
     
     
         4 . The pressure relief device of  claim 1 , wherein the band is configured to be worn on the outside of a compression garment. 
     
     
         5 . A garment retention device, comprising a flexible, radially inelastic band having first and second end portions and a groove, wherein the groove is configured to interlock the first and second end portions of the band in a closed-loop configuration.
