  • Fail-safe mechanical drive for syringe
    Patent number: 4676122
    Abstract: A mechanical drive system for driving a syringe, or other fluid infusion system, over extended period of times, which drive system also provides manual advance and quick release features. Manual advance and quick release is selectively provided by mechanically decoupling the gear train from the syringe drive mechanism.

  • Fail-safe mechanical drive for syringe
    Patent number: 4602700
    Abstract: A high reliability drive arrangement produces a rate-controlled output displacement and is particularly suited for driving a medical infusion apparatus. Energy for producing the output displacement is derived from a wound spring which, in a preferred embodiment, is coupled to an output shaft by a redundant gearing system. First and second drive gears, and their associated pinions on the output shaft, are rotationally displaced with respect to one another to prevent alignment of potentially defective gear teeth and to align the teeth on one gear with the inter-tooth spacings on the other. The output shaft additionally engages a rate-control arrangement which governs the rate of rotation, and consequently, the rate of the displacement. The possibility of uncontrolled rotation is reduced by providing a safety arrangement having a safety gear plate which has fewer teeth than its associated drive gear.

  • Fluid infusion apparatus
    Patent number: 4044764
    Abstract: A portable, automatic fluid infusion apparatus is presented for the administration to an ambulatory patient of a predetermined amount of fluid at an adjustable, predetermined rate over an extended time period. A feature of the invention is a soft plastic bag from which the predetermined amount of fluid is dispensed.

  • Fluid infusion apparatus
    Patent number: 3993065
    Abstract: An improved fluid infusion apparatus is presented of the type having a power means and a syringe connected therewith. The syringe is comprised, in part, of a piston and a cylindrical body. The improvement comprises a flexible connecting member for connecting the piston of the syringe to the power means, thereby permitting the syringe to be responsive to the power means, even when the two are not coaxially aligned, for the administration of a predetermined amount of fluid at a predetermined rate.
