Abstract: An automatic injection control device injects fluid at a rate directly related to the displacement rate of the device body from a held positioning member. The device has a syringe end, a gripping end, a syringe barrel coupled to the body and a refillable reservoir and at least one directional valve at the syringe end of the body. The directional valves permitting refilling of the refillable reservoir without removing the syringe barrel. Also, a transmission system is coupled to the body, as well as the positioning member, a syringe plunging member, and a gearing mechanism linking the positioning member to the syringe plunging member. The device is designed so that when the positioning member is held in a fixed extended position and the body is pulled by the gripping end, the transmission system provides a one-way motion of the syringe plunging member to precisely inject fluid from the device.

Abstract: A single hand operable injection control device (ICD) automatically injects material into a subject tissue at a rate controllably proportional to the rate of movement of the syringe. Squeezing the figure holds rotates a transmission/timing belt that is connected to a position reference member/guide that pushes against the subject tissue, causing the ICD body (containing the syringe) to push away from the subject tissue. The timing belt turns a worm gear that drives a syringe plunger into the syringe held by the ICD. The coordinated motions result in precise delivery of a unit volume/region of injectate into the subject. That is, a uniform “tube” of injectate is automatically laid in the cannula track.

Abstract: An injection control device (ICD) for a syringe, injects/extracts material into/from at a rate controllably proportional to the rate of movement of the syringe. A transmission reference member is extendable outward from the ICD body, being connected to a transmission system/clutch which has an engage/disengage trigger for independent movement of a plunger arm. The ICD, via the transmission translates motion from movement of the body, in relation to a fixed state of the transmission reference member, to action on the plunger of an accommodated syringe. The clutch also allows the transmission reference member to be positioned, without transferring power to the transmission system.

Abstract: An injection control device (ICD) for a syringe, injects/extracts material into/from at a rate controllably proportional to the rate of movement of the syringe. The device has body with a first and opposite second side, syringe holder, first aperture in the first side to accommodate a cannula of the accommodated syringe, second aperture in the first side, and third aperture in the second side. A positionable transmission reference member may be linearly extendable from the second aperture; a spooling rotating member with an axle is coupled to the body; a clutch is coupled to the rotating member; and a transmission system is interior to and coupled to the body which translates body motion, in relation to a fixed state of the reference member, to move the plunger of the syringe, causing injected/extracted of material into/from a subject as the syringe's cannula is traveling with the moving body.
