VISUAL INFLATION PRESSURE INDICATOR AND SURGICAL TUBE INCLUDING THE INDICATOR
摘要
The present invention provides an indicator (10) for visually indicating a pressure level of a fluid in a pressure source. The indicator (10) comprises an inflatable body (33) having a notched section (40) with opposing edge portion (42) that are separated by a gap when the inflatable body is in an uninflated condition. The inflatable body further includes a port (36) for connecting the inflatable body to the pressure source whereby upon inflation of the inflatable body, there is a relative movement of the opposing edge portions in a direction so as to decrease the size of the gap and thereby indicate that a predetermined pressure has been reached in the pressure source. The indicator is particularly for indicating whether a predetermined pressure has been reached in an inflation cuff of an endotracheal tube.
