Abstract:
An adjustable flow syringe is provided that comprises a slidable plunger within a barrel. The barrel has a flow discharge end wherein a neck is located. The neck has a conduit extending therethrough which has an outlet and an inlet such that the conduit is in fluid communication with the barrel. The adjustable flow syringe includes either a valve insert or a porous insert in the conduit which is configured to adjust the flow rate of a fluid leaving the syringe such that a low amount of manually applied force delivers the fluid in drops. The valve insert is formed from a resilient material and conforms to the contours of the conduit. The valve insert has a portion that extends across the conduit outlet with an opening formed therethrough. The porous insert is formed from a porous material and is configured with a shape corresponding to the shape of the conduit so that fluid passes through the conduit primarily via the pores of the porous insert.
