Abstract

A medical treatment station which includes a medical treatment device such as a lithotripter including a liquid filled rotational ellipsoid as shockwave focussing chamber with a circular periphery and boundary and a liquid filled cushion e.g. bellows for coupling the treatment device to the body of a patient, the station further includes a rest or support for such a patient and structure for moving the treatment device and the rest in relation to each other, is improved by means a of safety device which includes a hollow, fluid-filled, elastic hose disposed along the periphery of the ellipsoid and inside the cushion; a pressure sensing transducer is coupled to the hose for sensing pressure therein including particularly any pressure increase if the periphery of the ellipsoid impacts upon another object such as said rest or support or the patient thereon so that the moving can safely be stopped.
