  • Patent number: 4392847
    Abstract: A system for injecting fluid into a patient and monitoring the blood pressure of the patient comprising an injector for incrementally injecting the fluid through a delivery tube into the vascular system of the patient at selected prescribed rates with display means and rate indicator means generating an output indicative of the rate of fluid injection connected to the display means for visually displaying the rate at which the fluid is being injected; a blood pressure monitor including transducer means communicating with the vascular system of the patient through the delivery tube on the injector for providing an output indicative of the patient's blood pressure and pressure detector means responsive to the output of the transducer means to generate an output indicative of the systolic and diastolic blood pressures of the patient; and mounting means for selectively mounting the blood pressure monitor on the injector and including connector means connecting the output of the pressure detector means in the bloo
