IMPROVEMENTS IN OR RELATING TO ULTRASOUND DEVICES

摘要

The invention provides an ultrasound probe (5) for use in a Doppler ultrasound haemodynamic monitor having a host signal processor (7) and an interconnect cable (9). The probe (5) includes a memory device, preferably in the form of E<2>PROM (23) wich communicates with the host processor (7) 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.
