This combination device consists primarily of a stem with a pointed float with plate means at one end, which is freely received in an opaque walled sensing chamber, that removably receives a sensing plug, which is attached to an alerting device, for indicating the ceasing of flow, of intra-venous fluid to a patient. The pointed float also serves as a means, for easy insertion of the flow-meter stylus of the assembly, during insertion, into a bottle of intra-venous fluid. The sensing plug includes a pair of prongs, one of which, has a light emitting diode therein, and the other prong includes a photo-sensitive transistor, and the plate end of the float stem, when lowered between the prongs by low fluid level, will activate the circuitry of an alerting device.

A combination intra-venous flow-meter and low level fluid mechanism, comprising, a hollow square housing of suitable material, a stylus tube fixedly secured at one end, over a central opening included in the top wall of said hollow square housing, and the opposite end of said stylus tube is removably received in the stopper of a bottle of intra-venous fluid, a stem freely and elevatably received in said stylus tube, a float fixedly secured at one end, to one end of said stem, for floatation on the intra-venous fluid level in its bottle, and a plate integral with the opposite end of said stem within said hollow square housing, in which the fluid travels, the bore of the stylus tube being the passageway means for fluid travel into said hollow square housing, and the end of said float is pointed, for easy insertion into the stopper of the bottle of intra-venous fluid.
