Abstract:
A recirculating micro ball bearing slide providing the frictionless mechanism for a movable block ( called a â€œkneeâ€  that is bolted to the ball bearing slide) and linear guide, providing the support and guide structure and housing for the knee and a stationary micro syringe holder and clamp; knee has a machined tapped hole in it for receiving a threaded rod; knee converts rotary motion of the turning threaded rod into its own linear motion along the guide rail; machined key slots on the knee receive and hold the plunger heads of two bilaterally arranged micro syringes; micro syringe clamp holds the barrels of the micro syringes stationary while the moving knee depresses the plungers in linear fashion causing extrusion of fluid from the micro syringes and into and through capillary tubing attached to the micro syringes for delivery of fluids into the freely behaving animal.
