Apparatus for effecting massages synchronously with the heart activity, and particularly with the interphases of this activity, and comprising, in combination, a visual indicator of electrical pulses provided with two independent input channels, both connected to respective sensors applicable to the individual; a discriminator parallel-connected to one of said visual pulse-indicator units, while the output thereof is fed to a signal generator which, in turn, is connected to at least one time marker, preferably electronic, which is connected on the one part to a third input of said visual indicator and, on the other, to a relay device linked with a power source and with at least a massaging assembly applicable to the desired area of the body of the patient.
A device is described for performing mechanical cardiopulmonary resuscitation. The device comprises a housing which in use is secured to the chest of a patient, the housing and securing means providing inelastic encirclement of the patient's chest. Pneumatically operated pressing means projects from the housing to bear on the patient's breast bone and suitable valving is contained in the housing to apply cyclic displacement of the pressing means.
A method and device to support blood circulation during ventilation of the lungs which include controlling the application of the respiratory gases to occur at a particular point in time in the heart activity, and applying a uniform pressure to resist expansion of the thorax cavity to increase pressure on the heart during the heart's systole. The device which applies a respiratory gas and the uniform pressure includes a control device which senses the heart's activity to determine the desired point in time of the heart cycle.
