GENERAL INFORMATION

INDICATIONS FOR USE

WSK-1011 device is intended for measuring systolic and diastolic arterial pressure and for rating pulse in patients aged from 15 and elder
with a cuff wrapped around a wrist. The device is recommended for use in patients with unstable (nonpermanent) blood pressure or hyper-
tension at home as a supplement to medical surveillance. The cuff is suitable for a wrist with a circumference of about 12,5 - 22,5 cm. Blood
pressure is measured in the range from 40 to 250 mm Hg and heart rate, in the range from 40 to 160 heartbeats per minute.

OPERATION PRINCIPLES

The device uses the oscillometric method of measurement. Connect a cuff to an electronic unit and wrap it around your wrist. When you press the
START/STOP button, the device starts the automatic infl ation, which is followed by the blood pressure measurement. The sensor element of the
device detects slight pressure oscillations in the cuff produced by the expansion and contraction of the brachial artery in response to each heart-
beat. Rhythm and amplitude of the pressure waves are measured and displayed on the LC display as a numerical value in millimeters of mercury.
The device has an arrhythmia indicator, as well as two memories with 60 cells in each calculating the average value.
NISSEI New Technologies
Fuzzy Infl ation Algorithm – is an algorithm for automatic selection of the cuff infl ation pressure. Using this algorithm, the device by
itself determines the pressure level to which it is necessary to infl ate the cuff based on the patient's systolic pressure. Owing to the
Fuzzy Infl ation algorithm the device becomes easier to use, while the measurement gets more comfortable and more accurate.
Arrhythmia indicator is a special icon on the display that informs on the irregular heartbeat, while the measurement result is
correct.
Touch control – is control of the device by slight touching it.
Detection of interference noises – indicator informs on the occurrence of noises that can aff ect the measurement result.
Pulse pressure – along with the measurement result the device displays the pulse pressure value. Pulse pressure is a diff erence
between systolic and diastolic pressure.
M-Cuff series is a unique cuff unit designed and patented by NISSEI. M-shaped cuff can read pulse wave simultaneously from two
arteries.
