BREASTLIGHT-ENLIGHTENED BREAST CANCER AWARENESS
BREASTLIGHT-ENLIGHTENED BREAST CANCER AWARENESS
2.Light wavelength & absorption: It shines bright red light through the breast tissue and is very effective at illuminating the inside of the breast.The red light at ~620nm is transmitted relatively well by the breast tissue and is strongly absorbed by Hemoglobin in the blood. When used in a dark environment the user can clearly view some of the internal structure of their breast including their own blood vessels. If there is a breast abnormality such as a blood filled cyst or breast cancer the device can allow the user to see a darker shadow associated with the absorption of the red light of the blood associated with the abnormality. The product is intended to be used after a woman has performed her normal breast self examination as a further check of the breast using a visual means as well as by tactile means. The device is not intended to be used as a diagnostic tool for breast self-examination but as an aid to women to be used to support the breast self-examination process.
Breastlight complete box = 740 grams
Volumetric weight = 600 gram
Breastlight unit only = 300 gram
Breastlight has dual power supply options
1.5V, 4 x 1500 mAh AA NiMH rechargeable battery.
Low discharge NiMH battery has been used in Breastlight. Battery is capable of holding 500 full charges.Charging time from fully discharged to fully charge is about four hours. There is no provision for forced ventilation required to reduce this time.
2.Charger -DC power supply,9V DC with Minimum 0.6 Amps load
Frequency range: 50-60Hz, Input voltage range 110 – 240V.
The device can be used while the mains lead is plugged in for recharging. Recharging is temporarily halted while the unit is powered on. Jack should resist accidental removal while device is being used. The DC jack socket and main PCB are to be protected from damage resulting from a sideways pull on the power cable. A 2m cable length is required to ensure that a standing user has unimpeded use of the device when plugged into a low level socket.
Peak output Charger Rechargeable Battery
Tension (V) 9 volts 4.8 volts
Current (A) 600 mAmps 1500 mAh
Power (W) 5.4 watts 5.4 watts
Electric Requirement 110 – 240 volts, 50 / 60 MHZ Frequency
Maintenance: Breastlight is designed to be maintenance free.
Little heat is produced due to 3 LED’s so being on safer side heat sink is installed in unit for thermal management. Ideally the breast tissue should feel no heat sensation at all, i.e. temperature of housing stabilizes at approximately 40C. Maximum temperature of external surface of housing before thermal cut-out is triggered is 45C.
