ABSTRACT:
A flow regulator for drip infusion, comprising a rigid main body in which a rigid flow path is integrally formed. The flow path is substantially omega-shaped, and has a V-shaped cross section in its middle section, of which the upper side is open and closed by a flexible disc which has a ridge extending perpendicular to the flow path and can be pressed to change the effective size of an orifice formed between the ridge and the V-shaped flow path, thereby allowing for a stable control of the flow rate.
