With
the UM-101 you record blood pressure just like a
Mercury column using a stethoscope and listening
for Korotkoff sounds.
The A&D UM-101 Mercury-Free Manual
Sphygmomanometer recently passed a full clinical
validation study according to the
European Society of Hypertension International
Protocol and is suitable for use within a
clinical environment.

The story and development of the
UM-101 took place over a period of almost 2
years. From an early stage and following
feedback from healthcare professionals it was
decided that the function of the unit should be
identical (with some subtle improvements) to the
existing mercury sphygmomanometer so that a user
did not have to alter his/her working habits.
By
talking to Nurses and Doctors it became clear
that when
they use their sphygmomanometers listening for
Korotokov sounds means more than simply
measuring blood pressure. It can be a means of
communication between a nurse or doctor and
his/her patient.
The development of the UM-101 also allowed A&D
to implement improvements over existing
sphygmomanometers. For instance, the existing
mercury column is slow to respond to pumping and
there is a time lapse between the pump and the
pressure indication on the scale because of the
mass of the mercury. This can lead to pumping up
to unnecessarily high pressure levels.
There was also room for aesthetic improvement to
make the new product lighter and ergonomically
more modern in appearance.
Technical challenges and the need for an
innovative design faced the A&D R&D team. They
knew that conventional LCD’s or liquid crystal
displays are too slow to show changes in
pressurization in real time but managed to
overcome this and other technical difficulties.
2006 was the 101st year of the discovery of
Korotkov sounds and we hope that the UM-101 will
contribute to Korotkov’s discovery and establish
itself as a vital instrument in the
environmentally conscious world of the 21st
century.

MHRA
guidance, Ref.
MDA/2005/069, states that
“Calibrated non-mercury devices, which
do not rely on oscillometry, should be
made available in all clinical areas” it
also states that “In those clinical
conditions where oscillometry is
inappropriate (e.g. arrhythmias, pre-eclampsia
and certain vascular diseases) an
alternative method of pressure
measurement (auscultation, arterial
cannulation) should be used”. The UM-101
meets this requirement.
