Drip Monitoring Device
The Drip Alert? device is a supplementary intravenous drip monitoring system for the drip rate of fluids being administered, using an intravenous administration set.
The Drip Alert™ device is a supplementary intravenous drip monitoring system for the drip rate of fluids being administered, using an intravenous administration set.
If the drip rate of fluid passing through a drip-chamber falls outside the acceptable rate of variation, an alarm will sound. The device is for use in either hospital or home healthcare settings. Drip Alert™ is a passive device that does not control the drip rate of fluids passing through a drip chamber; it acts solely as a monitoring tool, the company says.
The device uses a microprocessor, a standard infrared drop sensor unit, and a power source in the housing that is capable of being attached to the drip-chamber of an intravenous administration set. The drop-sensing unit has one infrared emitter and two infrared receivers.
The housing is made of flexible plastic and has a U-shaped arm capable of attaching to both macro and micro drip-chambers of intravenous administration sets and has a smaller arm for attaching to the IV tubing so that the device is securely attached to the administration set. Two AAA alkaline batteries power the device, which has an on/off switch. When the switch is in the on position, battery power is provided to the microprocessor. The microprocessor contains a 32768Hz crystal clock that achieves a very high precision clock ratio. All electronic components within the device are low voltage. Using an algorithm, a drip-rate calculation is created.
The signal is used to indicate four functionalities: When the device is initially turned on, when calculating the initial drip rate, when deviation from an acceptable drip rate occurs and when the battery power is low. Different signals represent each of the conditions so that the user readily recognizes them, the company says.
The microprocessor also monitors the battery power source and will produce a constant audible sound if the battery power source is low.
