Injection Control Device for Proportional Injection, Extraction during the Syringe's Insertion, Retraction

A method of injecting/extracting material into/from a subject at a rate controllably proportional to the rate of movement of a syringe attached to an injection control device, the device comprising:

• an ICD body with a first side and an opposite second side, a syringe holder (fixing an accommodated syringe from movement in the body), a first aperture in the first side to accommodate protrusion from the body a cannula of the accommodated syringe, a second aperture in the first side, and a third aperture in the second side;
• a positionable transmission reference member linearly extendable outward from the second aperture in a direction of the cannula of the accommodated syringe, a portion of the reference member having an exposed hand or finger resting protrusion;
• a spooling rotating member with an axle coupled to the body and a spooled element coupled to the reference member;
• at least one of a directionally sensitive and lockable clutch coupled to the rotating member;
• and
• a transmission system interior to and coupled to the body, a reference member-directed section of the transmission being coupled to the clutch and a plunger-directed section of the transmission being coupled to a plunger of the accommodated syringe, the transmission system being configured to translate motion from movement of the body, in relation to a fixed state of the reference member, to action on a plunger of the accommodated syringe;
• placing the first side of the ICD with the accommodated syringe's cannula upon or into a subject's tissue;
• positioning the positionable transmission reference member;
• engaging the locking clutch;
• and
• pressing on the positionable transmission reference member from the opposite second side to cause the body of the ICD to move or manually withdrawing or advancing the body of the ICD,
• wherein the plunger action is proportional to the movement of the body, resulting in material being injected/extracted into/from the subject as the accommodated syringe's cannula is traveling with the body.
