Abstract: In accordance with one embodiment, a vibratory transducer has an armature suspended in a magnetic field. The armature has a plurality of electrical conductive paths to provide electrical current flow in said armature to react with said magnetic field and cause movement in the armature controlled by variation in the electrical current flow. A contact surface is secured to the armature, with a surface area for frictionally coupling to a corresponding surface area of a patient for example. Movement of the vibratory transducer induces movement in the patient, and the transducer can produce movement in the contact surface in at least two dimensions simultaneously. In one embodiment the contact surface is flat, while in alternative embodiments the contact surface is incorporated in a toroidal structure so as to surround part of the patient. Medical application can include treatment of bone fractures, oedema, and in elastography, amongst other applications.

Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11). The microprocessor (16) controls a servo (19), that in turn controls the fan motor (20) and thus the pressure of air delivered by the blower (10). The blower (10) is coupled to a subject's mask (ii) by a conduit (12). The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

Abstract: An automatic portable ambulant miniaturized system for applying pneumatic pressure to a body limb including a portable ambulant hand-held fluid source unit, a conduit for delivering fluid generated by the unit, and a pressure sleeve coupled to the conduit and adapted to envelop a body limb. The pressure sleeve contains individually inflatable cells, each cell being subdivided into longitudinally extending confluent intra-cell compartments along the axis of the body limb. The intra-cell compartments are inflated and deflated essentially simultaneously by the portable fluid source unit. To increase the peak venous velocity generated by any kind of external compressive force on a limb with any kind of tempo-spatial regime, the venous phasic flow is monitored to determine so that the venous flow generated by the external compressive force can be synchronized with the in-phasic natural venous flow.
