Pulse dynamic image information detecting device

Abstract

The invention provides a pulse dynamic image information detecting device, aiming at synchronously detecting the pulse information of the cun part, the guan part and the chi part during pulsing under the different pulse-taking pressures at the cun part, the guan part and the chi part. A slide block (18) is arranged at the upper part of a vertical axis (19), a Z-axis coarse-tuning knob (16) is arranged on a ring (27) at the lower part of the slide block (18), a Y-axis tuning knob (17) is arranged in the middle of the slide block (18), and one end of an X-axis tuning slide block (6) is arranged on the slide block (18) which is opposite to the Z-axis coarse-tuning knob (16) by a Z-axis fine-tuning knob (20); the other end of the X-axis tuning slide block (6) is in parallel with the horizontal plane and is provided with a groove, one end of an elastic bridge arm (7) is respectively arranged in the groove by a pulse-taking pressure tuning knob (5), and the other end of the elastic bridge arm (7) is respectably provided with a detecting contact head (9); one end of a sensor bracket (4) is arranged on the X-axis tuning slide block (6), and the other end of the sensor bracket (4) is provided with a CCD (charge coupled device) sensor (3); and the detecting contact head (9) is a cylindrical component with a seal cavity (21), a cylindrical wall of the detecting contact head (9) is provided with an air inlet (10), the upper end of the detecting contact head (9) is sealed by a photo-permeable glass piece (8), the lower end of the detecting contact head (9) is sealed by a silica gel film (14) with grid texture, a light source (11) is arranged in the middle of the cylindrical wall of the detecting contact head (9), the seal cavity (21) is connected with an air pressure cushion cavity (26) by an air pipe (24), the air pressure cushion cavity (26) is connected with a pressure gauge (23) by the air pipe.

Description

technical field [0001] The invention relates to a detecting device for pulse information of traditional Chinese medicine. Background technique [0002] At present, the detection devices for pulse information mainly include single-part, double-part, three-part and multi-point types. Single pulse information detection device is the most common. It only detects one of the three parts of inch, guan, and ruler. Most of the sensors used are pressure sensors, and the pulse information obtained is limited and one-dimensional. The double-part type can only detect the information of two of the three parts of inch, guan, and chi, and it is also one-dimensional information, and the amount of information is also limited. The three-part pulse detection system developed by Shanghai University of Traditional Chinese Medicine can extract the pulse signals of Cun, Guan and Chi, but it uses the strain-pressure sensing probe. In order to collect more comprehensive pulse information, Professor...

Problems solved by technology

Due to the limitations of the type of sensors and the number of detection parts of these detection devices, it is difficult for the collected information to fully and accurately reflect the constituent elements of the pulse condition, which is quite
