Title:
静脈内液体のための流量計
Document Type and Number:
Japanese Patent JP6721671
Kind Code:
B2
Abstract:
A flow meter for intravenous liquids comprising a vertical inlet passage (2), a parallel indicating chamber (9), a ‘U’ shaped flow-resistant liquid passage (6), and an exit chamber (11). Liquid to be dispensed enters the inlet passage (2) via inlet (5) and moves down the passage to a junction with both the ‘U’ shaped flow-resistant passage (6), and the indicator passage. From the junction, the liquid rises up the indicator passage to a height proportional to the flow rate set by an external flow meter, and also through the flow resistant passage, which has an outlet (8) that delivers the liquid to the exit chamber (11) and from there to a patient through an outlet (12). The meter may be formed by an assembly of two injection molded components, thus reducing manufacturing costs.
