introduction to Laser Blood Perforator
Laser Perforator is based upon the use of pulse of
laser light, of which the wavelength is 2.94μm and
the instant temperature would reach around 1K℃
with extremely short time (no more than 500μs), that
ablates (melts) and boil off the cuticle to form a
tiny hole, and then realize the collection of blood
sample. The laser beam is absorbed by water in the
skin resulting in a small puncture in the finger
without immediate or lingering pain. The blood and
skin not in the laser beam path are not affected by
the laser energy. Many users of the device report
feeling less pain resulting from the use of the Laser
With the use of Laser Perforator, any possibility of
infectious disease transmission while drawing blood
samples is completely eliminated. It goes without
saying that the non contact penetration is a
revolutionary breakthrough in clinical medicine.
Europe Countries, America and Russia have already
adopted Laser Perforator successfully in clinical
In today's world where blood infectious disease
plagues, the Laser Perforator enjoys great popularity
Characteristics of laser pulse (wavelength=2.94μm):
1)Near water's absorption peak, it can be absorbed
easily by water.
at near-infrared band, its instant temperature is
extremely high (1K℃).
Making use of the above two advantages, Laser
Perforator controls the amount of output energy,
making the operation safe and reliable.
1)No cross infection
acus-pricking blood collection may have many
possibilities to lead cross infection, while using
Laser Perforator, the non-contact blood collection,
there is no worry
about infection. In particular, the instant high
temperature of laser beam will effectively kill the
epidermal germs and performs sterilization of skin
surface. What's more, the one-off shield isolates the
vaporizing material of skin protein, thus completely
cutting off the cross-infection channel.
2)No pain & No psychological stress
Laser Perforator collects blood sample by penetrating
skin surface in a limited time. The released energy
could only penetrate epidermal tissue while keeping
away from nerve. That is why the pain effect is
minimized. Without lancet, patients' psychological
stress is greatly reduced. This is especially good
news for infant and children.
3)High-purity sample blood
Laser Perforator output an extremely high-temperatured
laser beam, making the pore form protein denaturation
(Gel Status) so as to avoid impurity to mix into blood
sample. And thereby the high quality blood sample
ensures the accuracy of detection.
4)Easier collection process
Unlike traditional lancet which requires personnel
having proficient skills, Laser Perforation can be
finished just by pressing a button.
