2.4 NIBP Measurement
104
The device has protection for the maximum pressure in the cuff (< 300
mmHg for adults and 150 mmHg for newborns).
The device has protection for the maximum pressure measurement time
(<180 s for adults and 90 s for newborns).
2.4.3. Check of the Cuff Tightness
Untightened cuff can be the reason of inaccurate BP measurement. Check the cuff as follows:
Connect the tested cuff with a pressure gauge and a hand pump ("bulb"). For that you can
use a normal serviceable medical device for manual measurement of blood pressure by
connecting the tested cuff to it instead of its standard cuff.
Place the tested cuff on a solid, non-wrinkling cylinder of a suitable diameter (for example, a
bottle or can).
Using a hand pump ("bulb"), pump the cuff up to 150 ... 200 mmHg and, by closing the
bleed valve, check the rate of pressure drop in the cuff on the pressure gauge, which shall
not exceed 5 mmHg in 10 sec. Take into account that many
“bulbs” can have their own leak,
therefore, during test it is recommended to pinch the hose that connects the bulb.
Note:
In the absence of a pressure gauge, it is possible to detect air leakage from the cuff con-
necting hose and the place of their joint, when the previously inflated cuff is immersed in water
and pressing on it. It is necessary to exclude the possibility of water getting into the hose by
tightly plugging its hole.
The untighten cuff must be replaced. If you use the untighten cuff, your BP measurements may
be distorted.
2.4.4. Cuff Disinfection
Disinfection of the cuff is carried out in accordance with the requirements of MU-287-113 by
wiping it with a 3% solution of hydrogen peroxide with the addition of 0.5% neutral detergent of
the "Lotos" type (it is allowed to use other disinfectants of different manufacturers, taking into
account the method of their use).
DO NOT allow liquid to enter the cuff or connecting hose!
IT IS STRICTLY FORBIDDEN to process the cuff and hose by immersing
them in liquid, because liquid can get into the pneumatic path of the device
and damage it. IN SUCH CASE THE WARRANTY REPAIR IS NOT PER-
FORMED.
To prevent accidental ingress of liquid into the cuff, if possible, remove the rubber chamber from
it before disinfection, and after disinfection put it back again. Make the following steps:
pulling on the hose, carefully remove the rubber chamber from the outer cover of the cuff
(see Fig. 2-22, a);
disinfect the cuff (if immersion in liquid was used, be sure to let the cuff cover dry complete-
ly!);
roll the chamber on both sides towards the hose (see Fig. 2-22, b) and, bringing the rolled-
up chamber to the cuff opening, push it inward, avoiding distortions and bending of the
chamber (see Fig. 2-22, c), and then straighten the chamber inside the cuff.

DO NOT use a cuff, if the liquid has entered inside, as it can damage the de-
vice, and its WARRANTY REPAIR IS NOT PERFORMED
