Abstract: Method and apparatus for injecting fluids into patients at a controlled rate from an ampule containing the injecting fluid with a sliding piston therein to force the fluid from the ampule into the patient using a drice system which incrementally and successively advances the piston in the ampule to meter the fluid into the patient.

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

Abstract: Method and apparatus for injecting fluids into patients at a controlled rate from an ampule with a tubular side wall closed at one end with a penetrable plug and a sliding piston in the side wall to force the fluid through an opening in the penetrable member using either a long duration injector with an expelling means to move the ampule piston, drive means for operating the expelling means, and control means for incrementally and successively connecting and disconnecting the drive means to the expelling means or a short duration injector with a spring drive or a fluid pressure drive to move the ampule piston and meter the fluid through a metering device.

Abstract: Method and apparatus for injecting fluids into patients at a controlled rate from an ampule with a tubular side wall closed at one end with a penetrable plug and a sliding piston in the side wall to force the fluid through an opening in the penetrable member using either a long duration injector with an expelling means to move the ampule piston, drive means for operating the expelling means, and control means for incrementally and successively connecting and disconnecting the drive means to the expelling means or a short duration injector with a spring drive or a fluid pressure drive to move the ampule piston and meter the fluid through a metering device.

Abstract: A subcutaneous injection system for injecting fluids in the subcutaneous fat layer of a patient including an injection needle having a sharpened end thereon for penetrating the subcutaneous fat layer of the patient and a locator pad carrying the needle with the locator pad having a locating surface to lie against the patient's skin from which the sharpened end of the needle projects a prescribed distance while oriented generally normal to the locating surface to positively control the depth of penetration of the sharpened end of the injection needle into the subcutaneous fat layer of the patient.
