Description

Technical Field

[0001] The utility model relates to the technical field of sphygmomanometers, in particular to a portable sphygmomanometer. Background Art

[0002] Sphygmomanometers mainly include auscultatory sphygmomanometers and oscillometric sphygmomanometers. The oscillometric method, also known as the oscillation method, is a relatively advanced electronic measurement method. First, tie the cuff to the arm, automatically inflate the cuff, stop pressurizing after reaching a certain pressure, and start to deflate. When the air pressure reaches a certain level, blood can flow through the blood vessels, and there is a certain oscillation wave. The oscillation wave is transmitted to the pressure sensor through the trachea. The pressure sensor can detect the pressure and fluctuations in the measured cuff in real time. Gradually deflate, the oscillation wave becomes larger and larger. When the cuff is deflated again, the contact between the cuff and the arm becomes looser, so the pressure and fluctuations detected by the pressure sensor become smaller and smaller. Select the moment of the largest fluctuation as the reference point. Based on this point, look forward for the fluctuation point with a peak value of 0.45, which is the systolic pressure, and look backward for the fluctuation point with a peak value of 0.75. The pressure corresponding to this point is the diastolic pressure, and the pressure corresponding to the point with the highest fluctuation is the average pressure.

[0003] However, the cuffs of existing electronic blood pressure monitors are mostly connected by Velcro. Since the arm needs to be put into a strap, it is inconvenient to tighten and fit the arm with the other hand. Complicated operation steps are required, and one-handed operation is not convenient enough. The strap is not easy to store when not in use, and the long cuff is easy to be repeatedly wrapped and adhered, resulting in poor use effect. Based on this, the utility model designs a portable blood pressure monitor to solve the above problems. Utility Model Content
