Aesthetic
work stations use dynamic pulse control technology to deliver a range of safe
and professional applications for the growing aesthetic and anti-aging markets.
Thermoelectric skin cooling, precise optical filtering, and unique energy
pulsing offers high treatment efficacy while maximizing patient safety and
comfort. The operator uses a handheld instrument, which is wire connected to
the work station and locked with a bayonet quick connector. The quick connector
allows the user to switch the handheld instrument within seconds. In that way,
one work station can be used with different handheld instruments, offering
different functions, which include the following:
·
Hair
removal & hair reduction
·
Removal
of benign pigmented epidermal & cutaneous lesions
·
Removal
of vascular & pigmented lesions
·
Inflammatory
acne removal
The bayonet
quick connector allows for a quick and comfortable change of the handheld
instrument (with different functions for the above described treatments)
without specific tooling and training for the operator.
To ensure the
connection and disconnection can be processed easily, the tolerances of the
male and female component of the bayonet connector are manufactured with a
loose fit.
This loose fit, however, causes the connection to become relatively
‘shaky’, which decreases precise handling of the handheld. In addition to the
‘shaky’ connection problem, it makes the product look cheap in quality.
To
remove axial and radial play between the male and female component, a rubber
O-ring was assembled. During the locking process, the rubber O-ring compresses,
enabling the male and female component to become pre-loaded against each other.
However, there is a major problem that emerges: after several changes of the
handheld, it causes a decrease in load and permanent deformation of the O-ring.
Because of
that, the rubber O-ring was replaced by a RotorClip TruWave single turn, flat wire, wave spring, which delivers an
accurate force after every change of the handheld. The TruWave wave spring
provides a force, which allows all operators to change the handhelds without
too much expenditure of energy and without tooling. In comparison to the rubber
O-ring, the TruWave wave spring does not lose its force because of deformation
after a specific time.
