Abstract
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 2PROM 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.
Claims17
An ultrasound probe for use in conjunction with a host processor to monitor physiological behaviour of a human subject, said probe including an electronic memory able to communicate with said host processor when said probe is in use, said electronic memory being configured and operable to store information relating to the accumulated time of use of said probe together with one or more patient physical details selected from the group consisting of weight, height and age.
An ultrasound probe for use in conjunction with a host processor to monitor physiological behaviour of a human subject, said probe including an electronic memory capable of communicating with said host processor when said probe is in use, said electronic memory including a plurality of time counters capable of communicating with a host counter in said host processor one of said time counters in said electronic memory indicating the lowest remaining time of use, said one of said time counters initiating the communication of said host counter with said plurality of time counters, the permissible time of use of said plurality of time counters being updated from said host processor alternatively between said plurality of time counters.
