The connecting seat 12 and the base 1 are screwed together through the threaded hole 13 and the external thread, and the stability of the device is improved through the base 1.

[0025] The bottom of the base 1 is provided with anti-slip grooves.

[0026] The calibration mechanism includes a calibration motor 6, an eccentric wheel 9, a swing rod 10, and a balance wheel 11. The calibration motor 6 is installed in the installation box 4. The eccentric wheel 9 is installed on the lower side of the output shaft of the calibration motor 6. The housing 3 is fixedly connected with a swing rod 10. The upper side of the swing rod 10 passes through the housing 3 and extends into the installation box 4. The upper side of the swing rod 10 is sleeved with a balance wheel 11, and the balance wheel 11 is located on the side of the eccentric wheel 9. A controller 8 is installed in the installation box 4. A display 5 for outputting the corresponding blood pressure value is installed on the outer wall of the housing 3. The controller 8 is electrically connected to the display 5 and the calibration motor 6. The housing 3 is simulated as an arm and measured by a sphygmomanometer. When the sphygmomanometer starts to deflate, the controller 8 controls the calibration motor 6 to rotate slowly, and a collision occurs between the eccentric wheel 9 and the balance wheel 11, causing the swing rod 10 to Driven by the collision, it makes a sound or generates vibration, simulating the sound and vibration generated when the blood vessels are just opened and blood flows through the blood vessels. The controller 8 controls the calibration motor 6 to gradually increase its speed, and then gradually slows down to stop, which is equivalent to the gradual opening of the blood vessels, the gradual flow of blood, and finally the process of stable flow.

In this way, it can well simulate the process of blood flowing through the blood vessels. The speed of the calibration motor 6 corresponds to the corresponding blood pressure, which is displayed on the display 5. If the measured value exceeds the error with the determined value, it means that the sphygmomanometer needs to be calibrated at this time, and the difference between the two values ​​can be used as the basis for adjustment.

[0027] The shell 3 is made of bionic silica gel and is filled with bionic silica gel. The pendulum rod 10 is made of elastic silica gel.
