Pressure sensor and blood pressure measurement device

Abstract

The invention relates to a pressure sensor and a blood pressure measurement device. The invention discloses a pressure sensor and a blood pressure measurement device with the pressure sensor. The pressure sensor includes a case and a pressure sensing element. Two opposite sides of the case have a concave portion and a convex portion, respectively. A recessed space is formed in the concave portion.The pressure sensing element is disposed on the case. When the convex portion pushes the pressure sensing element, the pressure sensing element is deformed and protruded toward the recessed space. The pressure sensor has a higher detection sensibility.

Description

【Technical field】 [0001] The invention relates to a pressure sensor and a blood pressure measuring device. 【Background technique】 [0002] Blood pressure is one of the important indicators to observe an individual's health status. Abnormal blood pressure, whether it is too high or too low, implies a problem with the individual's physiological condition, especially cardiovascular diseases that are generally difficult to detect from the outside. Due to the aging of the body function of the elderly, the risk of suffering from cardiovascular disease is high, so in the past, it was very important to measure the blood pressure of the elderly regularly for early detection and early treatment. However, modern people are under a lot of pressure in life, and the three meals a day are not normal, so the age of the group that needs to be monitored regularly has a downward trend in age. [0003] It is generally known that a desktop sphygmomanometer includes a cuff, a host and a rubber h...

Problems solved by technology

[0004] However, it is well known that the sphygmomanometer easily makes the subject feel uncomfortable during the process of increasing and decreasing the pressure, and the measurement takes too long, which reduces the willingness of the subject to measure, which is not conducive to long-term use

In addition, in terms of carrying around, the volume of the main unit and the cuff are too large, which is not conducive to monitoring blood pressure at any time

In addition, in terms of measurement accuracy and sensitivity, if the cuff is not properly installed or properly fixed at the measurement position, it may not be possible to accurately measure the blood vessel pulse signal or the sensitivity of the sensor will deteriorate , which will lead to inaccurate blood pressure measurement values, and even doubts about measurement failure
