Embodiment Construction

[0090] 1. The first embodiment

[0091] 1-1. Configuration of the pulse detection device of the first embodiment

[0092] First, as shown in FIG. 1 , a pulse detection device 1 according to a first embodiment of the present invention includes a stand 2 placed on the ground, and three pulse detection units 3 of the same type supported by the stand 2 . The bracket 2 is provided with a shaft 2a erected upright, an arm 2b attached to the shaft 2a, and a tension plate 4 is disposed at the front end of the arm 2b.

[0093] The installation height of the base end of the support arm 2b of the shaft 2a can be adjusted, and the support arm 2b can rotate around the rotating shaft 2a, and its position in the direction of rotation can be adjusted. In addition, the support arm 2b can rotate along the vertical plane, and its position in the direction of rotation can be adjusted. And these adjusting mechanisms are known, and its description is omitted. By adjusting the bracket 2, the posit...

Abstract

A pulse wave measuring device is provided with a plurality of pulse wave measuring units. Each pulse wave measuring unit has a supporting member to which a beam of a pressure measuring device is attached. Contact portions at the distal end of the beam is in contact with the patient's arm, so that piezoelectric elements mounted on the beam measures the stress variation according to pulsation of the patient's radial artery. The supporting meter has two pressing legs between which the contact portions of the beam are situated. The distal ends of the pressing legs are also pressed against the patient's arm. The pressing legs are harder than the radial artery. The interval between the pressing legs can be altered by handling a micrometer head. The contact portions are situated back from the distal ends of the pressing legs.

Description

technical field [0001] The invention relates to a pulse detection device, a pulse detection device and a pressure detection device. Background technique [0002] Accompanied by the beating of the heart, the pressure wave propagating in the blood vessel or the vibration of the blood vessel wall is generated, which is generally called the pulse. From the pulse, various medical information such as the state of heart movement can be obtained, so it has been used as a diagnostic method for palpation of the pulse in Eastern medicine for a long time. [0003] In Oriental medicine, the situation of palpation of the pulse is: the measurer presses the wrist of the subject with his fingers, and then measures the pulse of the radial artery by the sense of touch (finger sense). The magnitude of the pulse felt changes according to the pressing force at this time, but in the field of oriental medicine, the change of the pulse width (pulse amplitude) accompanying the pressure change of the...
