Visual inflation pressure indication and surgical tube including indicator

摘要

"VISUAL INFLATION PRESSURE INDICATION AND SURGICAL TUBE INCLUDING INDICATOR". The present invention provides an indicator for visually indicating a pressure level of a fluid at a pressure source. The indicator comprises an inflatable body having a notched section with opposite end portions that are separated by a gap when the inflatable body is in an uninflated condition. The inflatable body further includes an orifice for connecting the inflatable body to the pressure source, where upon inflating the inflatable body there is a relative movement of the opposing end portions in one direction to decrease the gap and indicate that a predetermined pressure has been reached at the pressure source. The indicator is particularly for indicating whether a predetermined pressure has been reached at an inflation cuff of an endotracheal tube.
