ABSTRACT:
A non-invasive intracorporeal movement transducer for translating intracorporeal movement into a detectable pressure signal is described. The movement transducer includes a fluid-filled bubble with a rigid rear portion, and a semi-rigid, flexible forward portion which is placed against a patient's skin above the organ to be monitored. The rear portion of the bubble has a fluid duct which provides fluid communication to the interior, and tubing is connected between the duct and a pressure sensor which detects the pressure of fluid within the bubble. Self-adhering attachment means is associated with the rear portion of the bubble for affixing the bubble against the patient's skin. In one embodiment, the attachment means is a foam backing larger than the bubble, with adhesive on one side for adhering to the patient's skin and to the rear portion of the bubble. The backing holds the rigid rear plate substantially fixed in approximately parallel relation to the patient's skin surrounding the area covered by the bubble.
