Abstract
Described herein is a compartment pressure monitoring device that enables the continuous monitoring of pressure in a physiological compartment, such as those found in the hand, forearm, upper arm, abdomen, pericardium, thigh and leg. In various embodiments, the device includes a tube connected at a first end to a balloon, and at a second end to a pressure gauge. A trocar sleeve may also be connected to the tube at or near its first end, such that a compatible trocar may be used to facilitate the insertion and positioning of the device within the compartment. The pressure gauge includes an alarm device configured to sound or display an alarm when a predetermined pressure threshold on the balloon has been met or exceeded. Also described is a method of continuously monitoring compartment pressure, using the compartment pressure monitoring device of the invention.
