Abstract
A tonometric blood pressure monitoring system is disclosed having a variable extension sensor assembly. The sensor assembly is connected to a central control unit through separable pod elements. Within the pod elements are a master cylinder and drive system for varying the extension of blood pressure sensor from the sensor assembly. The blood pressure sensor is mounted at the end of an sensor piston, the movement of which is guided on a central rod. The sensor assembly also includes a rolling bellows arrangement for providing a variable hold-down pressure between a cavity block and the sensor assembly housing. The blood pressure sensor is moved laterally, in one embodiment, to provide optimum lateral placement of the sensor with respect to a target source of blood pressure information such as the radial artery of the subject.
