Pressure sensor and blood pressure measurement device

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. 本发明涉及压力传感器及血压测量装置。本发明公开了种压力传感器及具有该压力传感器的血压测量装置。压力传感器包括壳体以及压力感测组件。壳体的两个相对侧分别具有凹部与凸部，其中凹陷空间形成在凹部。压力感测组件设置于壳体，且配置来受凸部挤压而朝凹陷空间形变。本发明的压力传感器可具有较高的感测灵敏度。
