Ventilator voice coil motor in the field of medical equipment:
Ventilator:Voice coil motors can be used to control the active
high-frequency round-trip movement of the ventilator cylinder valve
to realize the functions of switching from inhalation to exhalation
by inflating the lungs, discharging alveolar air, and switching
from exhalation to inhalation, etc., which provide support for
respiratory failure, anesthesia respiratory management during major
surgeries, respiratory support diagnosis and treatment and
first-aid resuscitation.
Biochemical autoanalyzers:In biochemical autoanalyzers, voice coil
motors are used to control the delivery of samples, the addition of
reagents, and the movement of detection parts to improve the speed
and accuracy of analysis.
Laser medical equipment: For example, in laser myopia correction
surgery equipment, voice coil motors can precisely control the
angle and position of the laser emission to ensure the safety and
effectiveness of the surgery.
Lightweight motion coils for short response times.
High precision wear-resistant optical shaft and miniature ball
bearing system, flexible cable output.
Low hysteresis force, low friction, good reliability.
1.4 The mass of the moving coil is less than 15g, the response time
is less than 20ms, the friction force is less than 50mn and the
hysteresis force is less than 40mn.
