Description

Technical field:

[0002] A sphygmomanometer, also known as a blood pressure monitor, is, as the name suggests, an instrument used to measure blood pressure. Existing sphygmomanometers include mercury sphygmomanometers and electronic sphygmomanometers, of which home electronic sphygmomanometers are mostly upper-arm type electronic sphygmomanometers, which include a main unit, a trachea, an arm cuff and other structures. The main unit can be powered by batteries or household AC power. Generally, a battery compartment is provided at the bottom of the main unit, which contains four battery mounting slots arranged side by side. When installing batteries, the positive and negative electrodes of adjacent batteries need to be distributed, otherwise power will not be supplied. For some older people, it is easy to be unable to start the machine and measure blood pressure due to installing the wrong battery. Moreover, when replacing the battery, it is necessary to press the positive terminal of the battery to cause the positive terminal of the battery to separate from the electrode sheet before the battery compartment can be removed. The operation is inconvenient, especially for people with short fingernails. Therefore, it is necessary to provide a structure on the sphygmomanometer that is convenient for battery installation and replacement. Utility model content:
