Problems solved by technology
At present, the blood pressure measuring instruments used by most medical institutions have not been included in the compulsory inspection, which has caused many hospitals to generally not pay attention to their measurement verification. There are many faults and hidden dangers in the phenomenon of uneven inflation and deflation of the air pump, which seriously affects medical treatment.

Description
technical field [0001] The invention relates to the technical field of medical measurement. Specifically, it is a non-invasive sphygmomanometer dynamic calibrator. Background technique [0002] Blood pressure measuring instruments mainly refer to cuff-type blood pressure measuring equipment such as semi / automatic electronic blood pressure monitors, blood pressure monitors (boxes), multi-parameter monitors (including non-invasive blood pressure detection systems). At present, there is no verification device and value transmission system for blood pressure measuring instruments in China. The research of the present invention has following important significances. [0003] ①Requirements for scientific research tasks: During the process of astronaut selection, astronaut training, astronaut daily inspection, spaceflight and other manned space missions, blood pressure is one of the important technical indicators to ensure the astronauts' health and judge the physiological indica...
