Blood pressure monitoring system

A system for monitoring the blood pressure of the patient, said system comprising:

• a. transducer means adapted to be directly coupled to the vascular system of the patient for providing an output indicative of the patient's blood pressure;
• b. filter means having a variable limit set in accordance with the patient's heart beat for removing a high proportion of the undesired frequency component from the output of said transducer means, the set limit of said filter means being high with respect to the patient's heart rate, said filter means passing a high portion of the signal components of a frequency corresponding to the patient's heart rate;
• c. systolic detector means responsive to the output of said transducer means for providing a first output indicative of the maximum magnitude of the patient's blood pressure;
• d. diastolic detector means responsive to the output of said transducer means for providing a second output indicative of the minimum magnitude of the patient's blood pressure;
• e. display means for displaying an indication of the patient's blood pressure;
• f. switch means for selecting one of the first and second outputs to be displayed by said displaying means;
• and
• g. processing means responsive to the magnitude of the selected output as derived from said switch means, for providing an output indicative thereof for a selected period of time to said display means.
