IMPROVEMENTS IN OR RELATING TO ULTRASOUND DEVICES

摘要

The invention provides an ultrasound probe for use in a Doppler ultrasound haemodynamic monitor having a host signal processor and an interconnect cable. The probe includes a memory device, preferable in the form of E <2>PROM which communicates with the host processor to limit the life of the probe and to render the probe inoperable in the event an attempt is made to use the probe in conjunction with more than one patient.
