The present invention provides a containing means for receiving the transmission medium for use With an ultrasonic wave source of an extracorporeal HIFU therapeutic apparatus, wherein the containing means for transmission medium is a semispheric membrane with a seating arragnment on an upper open end thereof for sealing connecting the containing means to the ultrasonic wave source, so that the membrane closes the ultrasonic wave emitting surface. The membrane is made from a material with an acoustic impedance close to that of the water, lower ultrasound transmission loss, perfect heat conductivity and good elasticity, such as latex, natural rubber, silicon rubber etc. The containing means can be used in the case that the ultrasonic wave source is mounted above the bed surface. It is easy to make the ultrasonic wave source rotated and tilted so that the inclining angle of the ultrasonic wave source may be adjusted as required so as to adapt to the variety of treatment requirements.
