Flow control device for administration of intravenous fluids
First Claim
1. In combination with an IV valve of the type for maintaining predetermined flow rates in an IV system having a source of fluid connected to an administration needle by means of flexible tubing, the IV valve to be interposed in the tubing line and having a body with generally longitudinally opposed ports connectable to the tubing to provide an inlet and outlet to the valve and having a dial operatively connected to a metering member movable to regulate flow through the said valve, a valve guard comprising:
- (a) a backplate defining a recess for receiving the body of said valve in a position with the dial accessible, said backplate extending longitudinally opposite said recess providing a gripping surface to allow the valve to be manually adjustable at said dial when said valve is held in the hand.

Abstract
A metering apparatus and system for controlling the administration of IV fluids having a valve housing with a valving chamber therein. A rotatable valve body member is positioned within the valve chamber and a valve passageway of variable cross-sectional area is provided at either the chamber or on the valve member. The effective area and length of the valve passageway interposed between the inlet and outlet 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 basic valve configuration including a backplate which facilitates single-handed operation and an optional cover plate 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.
