Patent ID: 8540681

Claim:
An injection control device (ICD), comprising: an external body having a distal and proximal end; a syringe supporting section coupled to the body; a transmission system coupled to the body, the transmission system containing a main gear, and a worm gear in contact with the main gear; a transmission system activating member housed within the external body, operably coupled and in contact with the main gear of the transmission system and linearly extendable from the distal end of the body beyond a distal end of the syringe supporting section; and a plunging member coupled to the transmission system, wherein the transmission system, activating member, and plunging member are configured so that a motion of the body of the ICD from a substantially fixed position of the activating member and the activating member's contact with the worm gear, causes the main gear to rotate, forcing a one-way motion of the plunging member to inject or aspirate material contained in the device, as the body of the ICD is moving, a rate of injection or aspiration being proportional to an amount of movement of the body of the ICD.
