Abstract

The invention provides a superficial vascular tissue pulsation displacement detection device and belongs to the field of biomedical engineering detection. The device is composed of a columnar device shell (2), three telescopic stand bars (11) arranged at the bottom of the device shell (2), a bottom plate (10) arranged between the bottom of the shell (2) and the stand bars (11), a direct current motor (9) embedded into one edge (12) of the bottom plate (10) and used for controlling the bottom plate (10) to turn over upwards around the edge (12), a first containing table (5), a second containing table (8), an array (7), a battery jar (3) and a signal processing circuit board (4). The first containing table (5) and the second containing table (8) are arranged in the device shell (2). The array (7) is arranged on the containing table (8) and formed by multiple laser ranging sensors. The battery jar (3) and the signal processing circuit board (4) are arranged on the containing table (5). A ranging work switch (1) is embedded into the top of the device shell (2). A display screen (6) is embedded into the surface of the device shell (2). The device has the advantages of being simple in structure, convenient to operate, small in error, large in dynamic range and visual in detection result display.

Description

Technical field: [0001] The invention relates to a device for detecting pulsation displacement of superficial blood vessel tissue, which belongs to the field of biomedical engineering detection. Background technique: [0002] The pulsation displacement of vascular tissue can be used to estimate parameters of vascular wall stiffness, such as vascular pulsation dilatation, Young's modulus of elasticity, pulse wave velocity, etc., which is of great significance in the diagnosis of cardiovascular and cerebrovascular diseases. The "contact" method is a common method for measuring the movement displacement of superficial vascular tissue, that is, the pulsation displacement is obtained by applying a sensor (such as an ultrasonic transducer, a piezoelectric sensor) to the surface tissue of the detection site. However, the external force applied to the tissue will introduce additional interference to the pulsation of blood vessels and surrounding tissues, which will increase the dete...
