The reason why the electronic sphygmomanometer can't inflate normally
1, the reason why the upper arm electronic sphygmomanometer can't pump air normally:
(1) There is air leakage in the armband or inflatable tube. When inflating, you can touch the trachea carefully to see where the air leaks. If the armband or inflatable tube leaks, a new inflatable armband can be replaced.
(2) The battery is insufficient. Check whether the battery model meets the sphygmomanometer. In addition, the battery has been used for too long and the power is insufficient. Just get a new battery.
(3) The inflatable tube and instrument are not plugged in;
(4) The arm moves in the process of pressurization. If the above points are normal, it is best to get a professional maintenance point for consultation and maintenance.
2, wrist electronic sphygmomanometer can't normal inflation:
(1) The battery capacity is insufficient, so use a battery model suitable for the instrument and replace it with a new battery;
(2) The airbag in the wrist cuff leaks air, which is the most likely failure of the wrist electronic sphygmomanometer. If you can buy the same model of cuff, you can open the instrument back cover and put on a new cuff, and then tighten the back cover properly. It is suggested that if you can't find the reason, you'd better take it to the maintenance point for consultation and maintenance, and don't disassemble the instrument yourself.
(3) The micro air pump is out of order. Generally speaking, micro air pumps are not easy to be damaged. If it is damaged, go directly to a professional maintenance point for maintenance.
