Abstract
Disclosed herein are compression bandages that include one or more fluid bladders (such as an air bladder) disposed in or on a bandage, such as an elastic bandage. In various embodiments, the one or more bladders may be adapted to apply focused pressure to a wound site, for example where direct pressure is required in order to stop or slow bleeding. In various embodiments, such a fluid bladder may permit sufficient pressure to be applied where needed, while also preventing the over-application of pressure to other tissues in proximity to the wound.
Claims20
A pneumatic compression bandage, comprising:
- a bandage;
- and
- a fluid bladder disposed on the bandage, wherein the fluid bladder comprises:
- an inflation mechanism for selectably inflating the fluid bladder;
- and
- a pressure indicator, wherein the pressure indicator provides an indication of the pressure within the fluid bladder.
A pneumatic compression bandage, comprising:
- a bandage;
- a fluid bladder disposed on the bandage;
- an inflation mechanism for selectably inflating the fluid bladder;
- and
- a non-slip material disposed on at least one side of the air bladder.
A pressure indicator, comprising an invertible dome, wherein the invertible dome undergoes a conformational change when the pressure in the invertible dome exceeds a predetermined threshold, and wherein the conformational change comprises a transition from a first conformation when the pressure is below the predetermined threshold to a second conformation when the pressure exceeds the predetermined threshold.
