[0079] First, refer to figure 1 A pulse detection device according to a first embodiment of the present invention will be described. figure 1 It is a front view showing the pulse detection device according to the first embodiment of the present invention.

[0080] Such as figure 1 As shown, the pulse detection device according to the first embodiment of the present invention includes a base (body base) G, a sensor (piezoelectric film sensor, not shown here), a side support portion (base fixing side) F, a connecting body (rotary Arm Connector) H, Rotary Arm D and Sensor Contact M. Among them, the sensor (piezoelectric film sensor) is used to detect the pulse of the object to be measured. The side support (base fixing side) F is fixed to the base (main body base) G. The connection body (rotary arm connection body) H is rotatably connected to the side support part (the fixed side of the base) F. One end of the rotating arm D is fixed on the connecting body (rotating arm conn...

[0098] Refer to the following Figure 3 to Figure 6 A second embodiment of the present invention will be described.

[0099] image 3 It is a plan view showing the elbow immobilization device of the pulse detection device according to the second embodiment of the present invention. Figure 4 to Figure 6 It is a cross-sectional view showing the height adjustment of the elbow immobilizer of the pulse detection device according to the second embodiment of the present invention.

[0100] Such as Figure 3 to Figure 6 As shown, the pulse detection device of the second embodiment further includes: an elbow fixing part (elbow pad) S, which fixes the elbow of the subject, and the elbow fixing part (elbow pad) S is relative to the base G of the pulse detection device. Adjustable distance and / or height difference.

[0101] Specifically, in order to immobilize the subject's elbow, the pulse detection device according to this embodiment includes an elbow immobilization device. The el...

[0111] Figure 7 It is a front view showing the pulse detection device according to the third embodiment of the present invention.

[0112] Such as Figure 7 As shown, the pulse detection device of this embodiment further includes: a wrist support part (hand rest) Q, which is mounted on the base (body base) G of the pulse detection device and has a shape conforming to the wrist of the subject.

[0113] Specifically, for example, based on the second embodiment of the present invention, in order to measure a stable pulse wave, this embodiment fixes both the elbow and the wrist.

[0114] On the side of the long side of the body base G, there is an adhesive sheet K2 near the end of the sensor contact M, which can be pasted with the adhesive sheet K1 on the side of the base R of the elbow fixed end, so that the elbow fixed end is fixed on one side of the body.

[0115] Further, a pad hand Q is newly added on the base G. The hand rest Q is a curved surface structure. In order to ...

Abstract

The invention provides a pulse detecting device and method. The pulse detecting device comprises a base (G), a sensor for detecting the pulse of a body to be detected, a lateral support member (F) fixed onto the base (G), a connector (H) rotatably connected to the lateral support member (F), a rotation arm (D) with one end fixed to the connector (H), and a sensor contactor (M) which is mounted at the other end of the rotation arm (D) and enables the sensor to be in contact with a part to be detected of the wrist of the body to be detected. The pulse detecting device can accurately exert pressure on the part to be detected when detecting the pulse of the body to be detected and accordingly obtain accurate detection signals. Besides, by arranging a plurality of sensors and a plurality of pressure sensors, which can be adjusted independently, the pulse detecting device can also achieve the pulse detection of cun-guan-chi and fu-zhong-chen in the TCM (traditional Chinese medicine) field and meanwhile achieve pressure quantification.

Description

technical field [0001] The invention relates to a pulse detection device and a pulse detection method, in particular to a pulse detection device and a pulse detection method used in the field of medicine, especially the field of traditional Chinese medicine. Background technique [0002] In the field of medicine, especially in the field of traditional Chinese medicine, it is often necessary to detect the pulse (usually the pulse of the wrist) of the measured body. When detecting the pulse of the wrist of the subject with the help of modern instruments, it is necessary to fix the wrist of the subject well and comfortably. [0003] Patent Document 1 discloses a radial artery pulse wave detection sensor fixing device. As described in Patent Document 1, how to accurately, quickly and conveniently fix the sensor at the detection point of the radial artery is an important content in the implementation of the detection of the radial artery pulse wave. The radial artery pulse wave...
