Medical fluid monitor

The Ruth's sister Fluid Reminder Alarm clips onto an infusion tube and uses a smart sensor to detect liquid-level changes in real time. The compact ABS housing measures approximately 3.5 by 5.5 centimetres and adds minimal weight to the line. A built-in rechargeable battery supports more than one year of continuous operation or several years of intermittent use when kept dry. Green LED flashes confirm the detection state after power-on.

Suitable for clinical and home infusion

Nurses and carers managing IV medication, blood products or nutrient solutions gain an audible alert when fluid stops flowing. The device works with tubes of various materials and colours and is designed for one-handed attachment. It is not intended for non-medical liquid monitoring, pressure sensing or automated pump control. Buyers needing wireless connectivity or data logging should consider other equipment.

3.5 by 5.5 centimetre footprint

The alarm's 3.5x5.5cm size determines whether it fits alongside existing tubing fixtures and clothing clips without obstruction. Charge the unit before first use, then press the power button to start monitoring. A long press while off cycles through sound options. No certification is claimed by the manufacturer.

Questions about this item

Should I pick the 3.5x5.5cm or the 1.37x2.16in version?

Both figures describe the same unit; 3.5x5.5cm equals 1.37x2.16in, so there is only one size to choose.

How does the 3.5x5.5cm footprint affect bedside use?

The compact 3.5x5.5cm body clips onto an infusion tube without adding noticeable weight or bulk during monitoring.

What connection standard does the alarm use and what does it limit?

It clips mechanically to the tube and has no data or power port, so it does not impose any interface bandwidth limit.
