Abstract

A carotid pulse measurement device provided for measuring carotid pulse of a user'"'"'s neck includes a band, an artery-pressing air cell, an inflating/deflating device, and a pressure detection unit. The band functions to surround the user'"'"'s neck. The air cell is arranged in the band and is fluidly connected to the inflating/deflating device for selectively inflating/deflating the air cell. The pressure detection unit detects variation of pressure inside the air cell. To use the measurement device, the band is put around the user'"'"'s neck with the air cell positioned exactly corresponding to the carotid artery of the neck so that the pressure detection device detects the pressure variation and generates a digital pulse signal, which is employed to calculate arteriosclerosis index of the user for evaluation the degree of arteriosclerosis of the user.

Claims

1. A carotid pulse measurement device adapted to measure pulse of carotid artery of a user, comprising:

a band adapted to surround a neck of the user, the band comprising an enclosing section and an effective pressing section;

an air cell arranged in the band at a location corresponding to the effective pressing section, and comprising a nozzle;

an inflating/deflating device fluidly connected to the nozzle of the air cell via an inflation tube for selectively inflating/deflating the air cell; and

a pressure detection unit arranged to detect pressure variation of the air cell and, in response thereto, to generate a pulse signal;

wherein to use the measurement device, the enclosing section of the band is put around the neck of the user to position the effective pressing section at a location corresponding to the carotid artery of the user'"'"'s neck.

2. The carotid pulse measurement device as claimed in claim 1, wherein the air cell comprises a plurality of inflation chambers, which are arranged inside the band in a stacked manner and are in fluid communication with each other and the nozzle.

3. The carotid pulse measurement device as claimed in claim 1, wherein the band has a skin-contact surface adapted to oppose skin of the user and forming an air-cell location indication zone at a location corresponding to the effective pressing section to allow ready recognition of the location of the air cell.

4. The carotid pulse measurement device as claimed in claim 1, wherein the pressure detection unit is fluidly connected to the air cell via the inflation tube of the inflating/deflating device so as to allow detection of pressure of the air cell and the inflation tube by the pressure detection unit.

5. The carotid pulse measurement device as claimed in claim 1, wherein the pressure detection unit is arranged between an air-contact surface of the band and the air cell to allow the pressure detection unit to detect the pressure variation of the air cell by means of reaction induced by the carotid pulse.

6. The carotid pulse measurement device as claimed in claim 1, wherein the band has two ends forming fastening sections on which fastener elements are mounted respectively for releasably securing the band around the user'"'"'s neck.

7. A carotid pulse measurement device adapted to measure pulse of carotid artery of a user, comprising:

a band adapted to surround a neck of the user, the band comprising an enclosing section, a first effective pressing section, and a second effective pressing section, the first and second effective pressing sections being spaced by a distance;

a first air cell arranged in the band at a location corresponding to the first effective pressing section, and comprising a nozzle;
