Patent ID: 7204809

Claim:
A pressurizing method for adjusting to an optimal pressurizing rate according to a cuff of various lengths, the method comprising the steps of: starting a pump for a pressurizing rate at a first stage and obtaining a measured pressurizing rate at the first stage by measuring pressures at two checkpoints; performing a control adjustment routine to control an adjustment of the pressurizing rate according the measured pressurizing rate, when the measured pressurizing rate R is larger than a second control condition R 2 , rapidly reducing the pressurizing rate to a preset value and then keeping pressurizing rate at the preset value, when the measured pressurizing rate R is smaller than a first control condition R 1 , increasing the pressurizing rate to the preset value and then keeping pressurizing rate at the preset value, when the measured pressurizing rate R is within the first control condition R 1 and the second control condition R 2 , keeping the pump to operate at the measured pressurizing rate R; pressurizing the pump according to the adjustment of the pressurizing rate, measuring a diastolic pressure value, keeping the pressurizing of the pump and then measuring a systolic pressure value and then stopping the pressurizing.
