A portable neuromuscular blockade monitor having application for (i) determining the type and degree of blockade present in a patient, (ii) determining the correct time for administration of muscle-relaxant drug or antagonistic drug, or (iii) determining the amount of muscle-relaxant or antagonist to be administered, comprises a dry battery of greater than zero but up to 12V output, a transistorized oscillator circuit to convert the D.C. energy from the battery into a series of electrical pulses which are of two fixed frequencies, the first being in the range of 1 pulse per second to 1 pulse per 10 seconds and the second being in the range p 25 to 250 pulses per second, a switch means for enabling either of these frequencies to be selected and maintained, a step-up transformer and potential divider on the stepped up voltage side of the transformer and a pair of terminals to take the pulse output from the device via the potential divider.
