EMITTER AND TUBE FOR INFUSION IRRIGATION

摘要

PROBLEM TO BE SOLVED: To provide an emitter stably producible from two or more components, and to provide a tube for infusion irrigation having the same.SOLUTION: An emitter 120 controls the flow rate of an irrigation liquid to be discharged from a discharge opening 112 of a tube 110 so that the flow rate decreases as the pressure increases within a predetermined pressure range, according to the pressure of the irrigation liquid within the tube 110 which is given to a second membrane part 153. The emitter 120 is composed by fitting of a first member 130 having a bottom face in a shape along the inner wall surface of the tube 110, and a second member 150 fitting into the first member 130 comprising the second membrane portion 153.SELECTED DRAWING: Figure 1
