Embodiment 1

[0026] The structure of the radial artery pulse wave detection device in this embodiment is as follows: figure 1 As shown, it includes a base 1 , a gear seat 2 , a rotating arm 3 , a sensor connecting body 4 and a sensor 5 . The bottom of base 1 is provided with slide rail 7, and slide rail 7 is equipped with slide seat 6, and slide seat 6 can slide on slide rail 7, to adjust its position. The sliding seat 6 is provided with a button 8 to control the sliding and locking of the sliding position of the sliding seat 6 on the base 1 . The bottom surface of the button 8 is connected with a tooth surface, and the inner side of the corresponding slide rail 7 is also provided with a tooth surface. When the button 8 is pressed, the two tooth surfaces are separated, and the sliding seat 6 can slide on the base 1. When the button 8 is released, the two tooth surfaces Engagement, the slide seat 6 is locked. The base 1 is provided with a supporting surface 10, and the sliding seat 6 is p...

Embodiment 2

[0032] Such as Figure 6 and Figure 7 As shown, compared with Embodiment 1, the radial artery pulse wave detection device of this embodiment has a different structure of the sensor connecting body 4 used to fix the sensor 5, and the sensor connecting body 4 in this embodiment is provided with a pressure regulating mechanism. The movement of the sensor 5 in the D direction is added.

Abstract

The invention discloses a radial pulse wave detection device, comprising a base, a sliding seat, a tooth holder, a rocker arm, a sensor connector and a sensor; the sliding seat is arranged on the sliding rail at the bottom part of the base, the sliding seat and the base are both provided with a supporting face for supporting and fixing a wrist; the tooth holder is fixed on the upper part of the base; the rocker arm is installed on the tooth holder through a revolving shaft; the joint surface of the rocker arm and the tooth holder is meshed by a tooth face; the sensor connector is installed on the rocker arm in a slip manner; the sensor is installed on the sensor connector; and the output end of the sensor is connected with a signal collecting device; and the output signal is successively processed by a computer. The radial pulse wave detection device of invention fully exposes radial pulse, maintains the detected person to be at a natural state, and simultaneously realizes rapid and accurate noninvasive detection of radial pulse, thereby solving the problems that the detection point position and external applying force are difficult to be determined, and the position of the detection point is easily to be changed in radial pulse wave detection process,.

Description

technical field [0001] The invention relates to a device for detecting radial artery pulse wave, which belongs to the technical field of human body signal detection of biomedical engineering. Background technique [0002] In each cardiac cycle, due to the contraction and relaxation of the heart, the pressure and volume in the arteries also change periodically, resulting in pulsation of the vessel wall, which is called the arterial pulse. The radial artery is considered an ideal site for pulse detection because it is located on the exposed part of the body surface and is easy to detect. Since the radial artery is located at the end of the upper extremity artery, where the pulse wave originates from the heart and passes through the central artery and the aorta, it contains rich information on cardiovascular status. Pulse diagnosis in traditional Chinese medicine uses the physiological and pathological information contained in the radial artery pulse to make a diagnosis. In a...
