Abstract
An indicator for a cuffed medical device, attached to a cuffed medical device to indicate internal pressure in a cuff of the medical device. The indicator includes: an indicator main body which includes a check valve adapted to be connected to an injection means for injecting a fluid into the cuff, a connecting section formed integrally with the indicator main body for connecting to the cuffed medical device, the connecting section communicating with the inside of the cuff, and a communication path for making the check valve and the connecting section communicate with each other; and a balloon provided in the indicator main body. The inside of the balloon is made to communicate with the communication path and is inflatable and deflatable in accordance with the internal pressure in the cuff. The balloon includes an index body which is moved forward and backward in accordance with the degree of inflation and deflation of the balloon in order to make the degree of inflation and deflation of the balloon visually recognizable. With the indicator for a cuffed medical device, a reduction in internal pressure can be readily and precisely determined.
