  • the apparatus of the present invention can stop the blood pressure measurement by pressing the emergency switch in the middle of measuring the blood pressure.
  • FIG. 9 is a flowchart for explaining the operation of the emergency switch in the two-arm blood pressure measuring apparatus of the present invention.
  • the two-arm blood pressure measuring device proceeds to step S71 and always monitors whether the emergency switch is pressed and turned on during operation.
  • the flow advances to step S73 to stop the air pump in operation to stop pressurization on the bladder.
  • the flow proceeds to step S74 to control the quick exhaust valve driving circuit 305 to open the quick exhaust valve 306 to exhaust air from the bladder.
  • the emergency switch is particularly useful in the process of measuring left and right bilateral blood pressure.
  • the emergency switch may be a foot switch 182 that operates with a foot, or may be in the form of a bar switch 184 that can be held by a hand in the form of a bar.
  • the air pump includes a left air pump 313 for pressurizing air to the left bladder 117, and a right air pump for pressurizing air to the right bladder 217. It is separated from 413.
  • the bladder 117 constituting the left cuff unit 110 is connected to the left air supply pipe 309 from the left air pump 313, and the left bladder pressure valve 333 is connected to the left air supply pipe 309.
  • the left bladder exhaust valve 353 and the quick exhaust valve 363 are attached.
  • the left air pump 313 is driven according to the drive signal of the left air pump drive circuit 311, and the left bladder exhaust valve 353 is driven according to the drive signal of the left bladder exhaust valve drive circuit 351.
  • the left quick exhaust valve 363 attached to the left air supply pipe 309 is driven in accordance with the drive signal of the left quick exhaust valve drive circuit 361.
  • the bladder 217 constituting the right cuff unit 210 is connected to the right air supply pipe 409 from the right air pump 413, and the right bladder pressure valve 433 and the right side are connected to the right air supply pipe 409.
  • the bladder exhaust valve 453 and the quick exhaust valve 463 are attached.
  • the right air pump 413 is driven according to the drive signal of the right air pump drive circuit 411, and the right bladder exhaust valve 453 is driven according to the drive signal of the right bladder exhaust valve drive circuit 451.
  • the right quick exhaust valve 463 attached to the right air supply pipe 409 is driven in accordance with the drive signal of the right quick exhaust valve drive circuit 461.
  • This apparatus of FIG. 10 is also operated by the flowcharts of FIGS.
  • the present invention can measure both arm blood pressure simultaneously without removing both arms in a safe, stable position.
  • FIG. 12 is a view showing a state in which the measurement results of the blood pressure of the left and right arms are displayed on the screen as the highest blood pressure, the lowest blood pressure, and the difference.
  • the left side of the screen displays the highest and lowest blood pressures of the left arm and their averages and pulses
  • the right side of the screen displays the highest and lowest blood pressures of the right arm and their averages and pulses. Shown below is the difference in the peak and bottom pressures of the left and right arms.
  • the present invention relates to an apparatus for measuring both arms blood pressure through simultaneous automatic measurement of both arms blood pressure.
