It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some embodiments, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present invention.

Referring to fig. 1, 2 and 8, fig. 1 is a schematic view of a main structure of a pulse feeling instrument according to an embodiment of the present invention; FIG. 2 is a schematic view of the pressurized bladder of FIG. 1; fig. 8 is a schematic diagram illustrating the connection between the pressurizing mechanism and the related components of the pulse feeling device according to an embodiment of the present invention.

As shown in fig. 1, 2 and 8 and according to the orientation of fig. 1, the pulse feeling instrument comprises a main body, such as a cylindrical housing (not shown in the figure), in which a pressurizing mechanism, a plurality of pressure sensors 12 connected with the pressurizing mechanism and a controller 6 in communication connection with the pressurizing mechanism and the pressure sensors 12 are arranged, the pressurizing mechanism comprises a pressurizing air bag 21 and an air pump assembly connected with the pressurizing air bag 21. Specifically, the mounting plate 13 is provided below the pressurizing bladder 21, the elastic layer 14 is provided below the mounting plate 13, the substrate 11 is provided below the elastic layer 14, and the plurality of pressure sensors 12 are provided in an array on the lower surface of the substrate 11. The pressurized air bag 21 comprises two opposite pressurized side walls 211 and a connecting side wall 212 connected with the two pressurized side walls 211, the pressurized side walls 211 and the connecting side wall 212 form a cavity for containing air, the pressurized side walls 211 and the connecting side wall 212 are made of the same material such as polyethylene plastic, nylon and the like, the thickness of the pressurized side walls 211 is larger than that of the connecting side wall 212, for example, the thickness of the pressurized side walls 211 takes any value of 1-3 mm, and the thickness of the connecting side wall 212 takes any value of 0.05-0.5 mm. An air inlet and outlet pipe 22 is provided on the upper pressure-receiving side wall 211, the air pump assembly includes an inflation air pump 51 and a vacuum pump 52, and the inflation air pump 51 and the vacuum pump 52 are connected to the air inlet and outlet pipe 22 through a three-way valve (not shown). An air pressure sensor 4 is provided in a pipe between the inflation pump 51 and the pressurizing airbag 21. The controller 6 is in communication with the pressure sensor 12, the air pressure sensor 4, the inflation pump 51, and the vacuum pump 52, respectively. Note that, for convenience of displaying the thicknesses of the pressure receiving side wall 211 and the connecting side wall 212, the end of the pressurizing balloon 21 is not closed by the connecting side wall 212, but this does not mean that the end of the pressurizing balloon in the pulse feeling instrument of the present invention is not closed.

During use, the controller 6 controls the inflation pump 51 to start inflating the pressurized airbag 21. In this process, the air pressure sensor 4 detects the air pressure value in the pipeline (equivalent to the air pressure value in the pressurizing air bag 21) in real time and feeds back the air pressure value to the controller 6 in real time. When the air pressure value in the pipeline reaches the set pressure value, the plurality of pressure sensors 12 abut against the skin layer 31 of the wrist at the set pressure, the controller 6 controls the inflation pump 51 to stop, and simultaneously controls the pressure sensors 12 to acquire pulse condition information of the positions corresponding to the cun, the guan and the chi of the radial artery 32 on the skin layer 31. After the pressure sensor 12 collects the pulse condition information, the controller 6 controls the vacuum pump 52 to pneumatically pump the pressurized air bag 21, so as to restore the pressurized air bag 21 to the initial state, such as the pressurized air bag 21 being in a vacuum state or a state where a small amount of gas is present in the pressurized air bag 21.

In the whole process of inflating the pressurizing airbag 21, because the thickness of the pressurizing side wall 211 is greater than that of the connecting side wall 212, the shape of the pressurizing side wall 211 does not change greatly along with the increase of the inflating amount, and the shape of the connecting side wall 212 changes greatly along with the increase of the inflating amount, so that the volume of the pressurizing airbag 21 is increased, and finally, under the extrusion of the lower pressurizing side wall 211, the plurality of pressure sensors 12 are pressed against the skin layer 31 of the wrist with approximately the same set pressure by the pressure transmitted by the substrate 11, so that the plurality of pressure sensors 12 can effectively acquire the pulse condition information of corresponding positions, and the accuracy of acquiring the pulse condition information is improved. Moreover, the wrist is stressed uniformly, and the comfort is improved.

In order to primarily deform the connecting side wall 212 during inflation while the pressure receiving side wall 211 substantially maintains its shape, the pressure receiving side wall 211 may be configured to have a rigidity greater than that of the connecting side wall 212, for example, the pressure receiving side wall 211 may be made of a material such as resin, the connecting side wall 212 may be made of a material such as rubber, and both of the two may have the same thickness, or the pressure receiving side wall 211 may be configured to have a rigidity and thickness greater than that of the connecting side wall 212, or other suitable configurations.

4. The pulse feeling instrument of claim 3, wherein the plurality of sub-balloons are arranged in an array on one annular face.

5. The pulse feeling instrument according to claim 1, wherein the pressurizing air cell comprises an elastic base body and a plurality of air chambers formed in the base body and communicating with each other so as to abut the plurality of pressure sensors against the surface of the wrist at substantially the same set pressure after inflation.

6. The pulse feeling instrument according to claim 5, wherein the pressurizing balloon maintains an initial state in which a shape of the pressurizing balloon matches a shape of a wrist in an uninflated state.

7. The pulse feeling instrument according to claim 1, wherein the pressurizing balloon includes two opposing pressure-receiving side walls and a connecting side wall connecting the two pressure-receiving side walls, the pressure-receiving side wall and the connecting side wall forming a cavity containing gas,

wherein the compression-side wall has a rigidity greater than that of the connection-side wall; and/or

The compression-side wall has a thickness greater than that of the connection-side wall.

8. The pulse feeling instrument according to claim 7, wherein the connecting side wall comprises a plurality of sub side walls connected to each other to form a folded structure, the folded structure being connected to the two pressure side walls, respectively.

9. The pulse feeling apparatus according to any one of claims 1 to 8, wherein the air pump assembly comprises an air pump for pumping out the gas in the pressurizing balloon.

10. The pulse feeling instrument according to claim 9, wherein a regulating valve is provided between the air pump assembly and the pressurizing balloon, the regulating valve being capable of regulating the flow rate of gas into and out of the pressurizing balloon.
