Lightmeter / 4meter

The 4meter is used for the determination of the actual level of sources required for effective medical therapy. The tool is useful for both hospital technicians and doctors who want to verify whether the medical equipment can deliver all the functions as designed.
The primary light meter function provides precise measurement of the intensity of the blue light spectrum that is necessary to treat jaundice in infants. This measurement allows health professionals to ensure phototherapy units are working correctly and determine when a phototherapy device or its bulbs need to be replaced.
The device can be used for any phototherapy unit with LEDs, fluorescent bulbs or compact bulbs. When measuring a single-sided phototherapy machine, it will measure the light using the front sensor. When measuring a double-sided phototherapy, the device reads the intensity from both sides, using the sensors on the front and back of the device. It then displays the sum of the values from each side.

TECHNICAL SPECIFICATIONS

ORDERING AND SERVICING

Quality

By measuring the wavelength spectrum from 400 to 520 nanometers, the light sensor gives a reliable irradiance measurement and helps to comply with the American Academy of Pediatrics Guidelines.

Innovation

The light sensor provides a quick and accurate measurement of therapeutic light intensity from any kind of phototherapy device to make sure that the patient is receiving the most effective amount of light.

Care

The device can also be used as a tool for clinical decision making, allowing the care giver to determine how to position the baby, maximize light exposure, and provide the strongest phototherapy.

Key Functions
1. Blue light irradiance measurement:
– verify irradiance of photo therapy devices during preventive maintenance and normal use
2. O2 measurement:
– verify purity of O2 sources (tank, generator, wall) during preventive maintenance
– verify mechanical blender and other blender during preventive maintenance
– leak search inside device and along external tubes during repair and equipment inspection
3. Pressure measurement:
– verify pressure at Y connector during use
4. Flow measurement:
– verify flow output of CPAP, Hi-flow and ventilators during preventive maintenance
5. High pressure measurement:
– verify hospital gas sources and check them for uctuations
6. Temperature and humidity measurement:
– verify the temperature uniformity of the radiant warmers
– check temperature and humidity inside the incubators

Light Irradiance Sensor
– spectral response chosen to match wavelength used for Jaundice treatment
– two sided measurement for convenient measurement of double-sided phototherapy devices such as MTTS Firefly.

Displays/Indicators
– touch screen liquid-crystal display (LCD)
– low battery
– 5 second result display time
– system failure
– out of measurement

Battery
– long battery life.
– standard AAA alkaline batteries are easy to replace

Easy To Use

The 4meter features a large, clear display that makes it easy to read under all lighting conditions.

Compact

The 4meter is lightweight and portable. It can be carried around easily and helps health professionals to feel confident in the therapy they provide to their patients.

Flexible

The 4meter can be used to measure the intensity of any type of phototherapy as well as the true level of flow, pressure and oxygen level of the gas sources.
