Problems solved by technology

Most of the existing measurement equipment is relatively large in size, not portable, and needs to be connected to the subject through a specific cable, so that it cannot be monitored in real time, and can only be measured once, which cannot meet the monitoring needs anytime and anywhere. The equipment has the problem of limited monitoring sensitivity

Embodiment Construction

[0015] see figure 1 , figure 1 It is a cross-sectional view of the wearable ultrasonic sensing device 1 in a preferred embodiment of the present invention. The wearable ultrasonic sensing device 1 is small in size and can be worn on a person's wrist, arm, etc. to monitor the user's body index information anytime and anywhere, such as blood flow rate, blood pressure, heart rate, etc. The wearable ultrasonic sensing device 1 includes a first protective layer 11, an ultrasonic receiving unit 12, a first adhesive layer 13, a circuit substrate 14, a second adhesive layer 15, an ultrasonic emitting unit 16 and a second protection layer 17 . In use, the first protective layer 11 is usually in direct contact with the human skin surface 10 . The ultrasonic receiving unit 12 is bonded to the circuit substrate 14 through the first adhesive layer 13 , and the ultrasonic transmitting unit 16 is bonded to the circuit substrate 14 through the second adhesive layer 15 . The ultrasonic tra...

Abstract

A wearable ultrasonic sensing device comprises a first protection layer, an ultrasonic receiving unit, a circuit board, an ultrasonic emitting unit and a second protection layer which are stacked sequentially. The ultrasonic emitting unit comprises a first electrode layer, a first piezoelectric layer and a second electrode layer which are stacked sequentially. The first electrode layer comprises a plurality of electrode units which are arrayed at intervals. The first piezoelectric layer comprises a plurality of piezoelectric units which are arranged between the electrode units and the second electrode layer respectively. One electrode unit, the second electrode layer and the piezoelectric units arranged between the electrode unit and the the second electrode layer form a piezoelectric sensing and detecting unit.

Description

technical field [0001] The invention relates to the research field of medical monitoring equipment, in particular to a wearable ultrasonic sensing device. Background technique [0002] Blood flow velocity and blood pressure are important monitoring indicators of cardiovascular diseases. Abnormalities of the cardiovascular system are often reflected by blood flow velocity and blood pressure. Therefore, real-time monitoring of blood flow velocity and blood pressure is of great significance for the prevention and treatment of cardiovascular system diseases. Most of the existing measurement equipment is relatively large, not portable, and needs to be connected to the subject through a specific cable, so that it cannot be monitored in real time, and can only be measured once, which cannot meet the monitoring needs anytime and anywhere. The equipment has the problem of limited monitoring sensitivity. Contents of the invention [0003] In view of the above, it is necessary to pr...
