| titleOfInvention | FLOW CONTROL ARRANGEMENT FOR THE INTRAVENOUS ADMINISTRATION OF LIQUIDS. |
| abstract | An apparatus and system for controlling and metering the administration of IV fluids. A rotatable valve body (502) is positioned within the valve chamber (505) and a valve passageway (509) of variable cross-sectional area is provided either in the chamber or on the valve member. The effective area and length of the flow passageway interposed between the inlet (506) and outlet (508) to the valve is adjustable to regulate flow by moving the valve body relative to the valve member. Various accessories can be selectively attached to the valve body including a backplate (510) which facilitates single-handed operation and an optional cover plate (550) which may be secured to the backplate to provide security from patient tampering. In the preferred embodiment the valve housing and internal valve members are fabricated from dissimilar plastic materials of different hardness to improve the sealing therebetween. In another embodiment, the flow passage has two circumferential portions (850, 860) interconnected by a bridge (855) to provide flow regulation over substantially 360 DEG range of rotation. |
