摘要

Automatic alarm for a medical drip comprises a clamp (10) which fits around a metering tube (52) through which liquid from the drip bag flows before reaching the patient. One arm of the clamp contains a signal generating device (21) and the other arm contains a receptor (22). A float (40) is positioned on the surface of the liquid in the metering tube and interrupts the signal when the liquid level drops below a predetermined level, generating a warning signal from an alarm (30).
