Do not start a new monitoring session with low batteries.
It is strongly recommended to use freshly charged accumulators or new batteries
with each patient so that batteries do not run down during monitoring, even in case
of very high blood pressure values and/or a long monitoring session. After inserting
batteries in Meditech ambulatory blood pressure monitors, it is advised to check
their voltage before programming them. The typical voltage for fully charged
rechargeable batteries should be over 2,5V and for fresh alkaline batteries, over 3V.
Battery voltage check: Press the Start button for at least 5 seconds.
If measurements do not start in due time keep fresh batteries in the recorder
If a recorder is not used for a long period, the in-built backup cell, ensuring the
operation of the internal clock, may get discharged. In this case keep freshly
charged batteries in the recorder for at least one day; this will recharge the backup
cell. It is possible to use the recorder afterwards. If the backup cell is not properly
charged, the internal clock may work incorrectly, and the recorder may not start
measurements in due time. If the recharging of the cell is not successful, the backup
cell must be changed by the service personnel. This is an out of warranty act.
If the batteries run down, replace them even during a monitoring session
Should the batteries run down during a monitoring session, they can be replaced.
Monitoring will continue and data will not be lost.
Remove the batteries if the recorder is out of use
If you do not use the recorder, it is advisable to remove batteries since they may run
down due to the constant small power consumption of the integrated circuits of the
device. Data in the recorder are not lost even if batteries run down or are removed.
Safety Concerns
Electric shock hazard protection
Both ABPM-05 and BlueBP-05 recorder meet the relevant shock hazard protection
standards. The devices operate with two 1.5V AA batteries or two 1.2V AA
rechargeable batteries, which excludes all electric shock hazards, even in the
unlikely case of multiple device errors.
Many personal computers do not meet shock hazard protection standards or strict
safety regulations applicable to medical devices. Therefore, during the computer-
based use of Meditech recorders, keep at least a 2 meter distance between the
patient and the computer. This is the required minimum safety distance. ABPM-05
communicates via a plastic optical cable, the 3 m standard length of which allows
for the required safety distance. The plastic optical cable ensures perfect electric
separation and reduces the effects of external electric noise. It does not conduct
electricity. BlueBP-05 recorders communicate via radiofrequency transmission
(Bluetooth). This ensures the perfect electronic separation from the PC.
Biocompatibility
To avoid infection risks, and for general hygienic reasons, the device, cuff and
tubing should never contact the patient's skin directly. Cuff materials meet the
related biocompatibility requirements.
