Powerful Motor Speed Inside Battery Dr Pen

Certified medical pen

The Essenlite pen is the new generation medical grate pen with newest research and technology , which is more effective and better than the old type. And certified by ISO13485, IEC60601-1 ,meeting all standards for medical-grade equipment in manufacturing, materials, sterile packaging and more.

Safest technology and design

Water proof and dust proof :IP22

PCBA board with moisture proof, anti-static, anti corrosion design,ensure the pen works in different environment situation. Besides, the PCBA board is designed to error automatic identification, when situation such as overload or malfunction happens, it will stop to protect the pen.

The Essenlite pen passed the type of current leakage tests:

Touch (leakage) current-NC

Touch (leakage) current -SFC

Patient leakage-NC ( DC current)

Patient leakage -SFC ( DC current)

Patient leakage -NC ( AC current)

Patient leakage -SFC ( AC current)

Patient leakage with mains on AP (Type BF)

Pen passed the type of high voltage insulation tests.

All tests ensure the Essenlite pen is safe enough as Class II medical device,meets the CE / FDA/ INMETRO demands.

Fastest and powerful motor on the market

The Motor speed designed from 6000 rpm to 8000 rpm, and controlled with 5 speed levels. The above motor design can safely guide the needles penetrate the skin at 3mm or glide over the skin at shorter length without scratching or tearing the skin tissues.This can decrease the epidermal damage and risk of infection,specially used together with the new generation Needle Cartridges.

The above speed, torque, together with the new generation needle cartridges, help reduce the treatment pain feeling, make the treatment much more effectively, and total noise less than 50dB.

The safest and powerful battery

Battery with overload guard plate to protect itself during charging and discharging. Most poor quality pens on market with the Li-polymer, capacity less than 500mah, in real working situation, working time less than one hour, and easy to emit heat during charging or discharging, tests show the during discharging ( within 20 minutes), surface temperature rise quickly up to 60℃-70℃, same test condition, our battery performs stable at 40℃-45℃. This performance can ensure the pen continue working , without temperature rise effects cause the halt or board malfunction.

Optimized compact design technology

  Adaptor- PCBA - Battery - Motor, all risk analysis control centre on the PCBA board. The board is designed to supply power as separate two ways, condition one: without adaptor, the pen will be drive by battery only; condition two: during batter charging, the board will drive the motor at same time to charge the battery, which means even the battery is out of life, the pen still can work with adaptor.

Often during the battery discharging process, the speed will be slow as the battery capacity decrease, but the Essenlite pen board is designed to supply stable voltage to ensure the stable speed level, till the designed end of discharging program.

More, the optimized design ensure the total pen ECM radiation meet CE IEC 60601 demands,more details,please refer the manual ECM part.

After sales service

The battery warranty life is 300 times circle life, others parts for the pen three years warranty ( then pen designed lifetime is five years), during the warranty, will fix free or send new ones to replace. All the pens before delivery will be tested as the ISO13485 lists,such as the functional testing list.

Needle length penetration control

When say the needle length, it means the length that penetrates deep into the skin length. The length from 0.25mm-2.5mm is designed with tolerance +0.25mm, which is longer than the dial.

First, there is gap between skin and the needle cartridge, second, years working will cause abrasion for the transmission.So, the tolerance is necessary, even consider the five years design life time. Other pens on market design the needles as the length high than the base, which is not reasonable.

Easy to use design

The pen with USB type line, able to connect adapter with output 5V/ 1A~3A, no need the appropriative adapter, if you have a USB cellphone adapter with output 5V/ 1A~3A.
