Referring to FIG. 3 , the base 200 includes a base 210 and a panel 220 covering the base 210 . The base 210 is in an arc shape as a whole. After being fixed with the wristband 100 and worn behind the wrist, the base 210 can better fit the curved surface of the wrist. The base 210 has a chamber 211 inside, and a liquid crystal display 400 and a fixing seat 500 are disposed side by side in the chamber 211 , and the panel 220 is covered on the top of the chamber 211 . The panel 220 is provided with a window 221 corresponding to the liquid crystal display 400 for the liquid crystal display 400 to display on the window 221 . In this embodiment, the fixing seat 500 is disposed in the cavity 211 , and the sliding seat 600 is disposed in the fixing seat 500 , the sliding seat 600 can slide in the fixing seat 500 , and the pressure sensor 300 is disposed in the sliding seat 600 . Specifically, sliding slots 510 are respectively provided on the two side walls of the fixing seat 500 , and sliding blocks 610 that can slide in the sliding slots 510 are respectively provided at both ends of the sliding seat 600 . The two sliding grooves 510 are arc-shaped sliding grooves 510 . And one of the chute 510 is hollowed out. A connecting post 620 is provided on the outer side of the sliding block 610 corresponding to the hollow sliding slot 510 , and the connecting post 620 protrudes from the sliding slot 510 . In this embodiment, since the fixing seat 500 is provided, another sliding groove 212 corresponding to the slotted sliding groove 510 is provided on one side wall of the base 210 . Of course, the fixing seat 500 can also be omitted, and the two sliding grooves 510 are directly provided on the two side walls of the base 210 , so that the sliding seat 600 directly slides in the base 210 .

Referring to FIGS. 4 to 6 , the sliding seat 600 is provided with a transmission assembly 700 that can drive the pressure sensor 300 to move along a direction perpendicular to the wristband 100 . The transmission assembly 700 includes a rotating shaft 710 , a driving gear 720 , a screw 730 , a driven gear 740 on the top of the screw 730 , and a nut piece 750 . The rotating shaft 710 is arranged horizontally. When the sliding seat 600 is placed on the fixed seat 500, the rotating shaft 710 passes through the connecting column 620 and protrudes from another chute 510 on the side wall of the base 210, and the rotating shaft 710 A knob 760 is provided on the extension end. The driving gear 720 is located at one end of the rotating shaft 710 inside the sliding seat 600, the screw rod 730 is vertically placed, the driven gear 740 is placed on top of it, the driven gear 740 meshes with the driving gear 720, and the nut sheet 750 is provided with screw holes (not labeled in the figure), the screw rod 730 is passed through the screw hole, and the bottom end of the screw rod 730 is fixed on the slide seat 600 . The pressure sensor 300 is also in the shape of a seat, and the pressure sensor 300 and the nut piece 750 are fixedly connected by screws. And the pressure sensor 300 is fixed in the sliding seat 600 at the same time. In this way, when the knob 760 is rotated from the outside, the rotating shaft 710 will rotate, the driving gear 720 will drive the driven gear 740 to rotate, and the screw rod 730 will rotate accordingly. When the screw rod 730 rotates, it pushes the nut plate 750 and the pressure sensor 300 to move up or down along the screw rod 730 instead of rotating. At the same time, since the rotating shaft 710 passes through the connecting column 620, the protruding end of the rotating shaft 710 also functions as a shifting block. When the knob 760 is only moved to slide along the chute 510 instead of rotating the knob 760, the sliding seat 600 slides in the base 210, so that the pressure sensor 300 is facilitated to search and align the radial artery. Since the base 210 is designed in an arc shape, the pressure sensor 300 slides along the arc, so that the sensing plane of the pressure sensor 300 is parallel to the arc surface of the wrist, so that the detection data is more accurate.

In this embodiment, the pressure sensor 300 and the sliding seat 600 are clamped. Buckles 630 are respectively provided on the two side walls of the slide seat 600 , and the two side walls of the pressure sensor 300 are respectively provided with fastening holes 310 for the buckles 630 to be inserted into. The buckle 310 connection is adopted to facilitate assembly and disassembly.

Please refer to FIG. 1 and FIG. 3 again, the base 200 is further provided with a first indicator light 222 for prompting the pressure sensor 300 to move laterally under the drive of the sliding seat 600 . When the slide 600 is sliding, the first indicator light 222 is red, and when the slide 600 drives the pressure sensor 300 to search for the radial artery and is aligned with the radial artery, the first indicator light 222 turns red from red to green.

At the same time, the base 200 is also provided with a second indicator light 223 for prompting the pressure sensor 300 to move radially under the drive of the transmission assembly 700 . When the pressure sensor 300 starts to move under the drive of the transmission assembly 700, the second indicator light 223 is displayed in red; is green.

As an extension of the function of the hand-worn blood vessel hardness tester in this embodiment, an electrocardiogram detection conductive sheet 230 that can be attached to the hand is provided inside the base 200 for heart rate detection and ECG monitoring. The electrocardiographic detection conductive sheet 230 is arranged on the back of the liquid crystal display 400, that is, the inner side of the base 200, so that it can better contact with the human skin during use and facilitate more accurate detection.

As an extension of the functions of the hand-worn blood vessel hardness detector in this embodiment, a blood oxygen detection sensor 240 is also provided on the base 200 . The blood oxygen detection sensor 240 is arranged on the side wall of the base 200. When in use, the wristband 100 needs to be removed, and the blood oxygen detection sensor 240 is placed close to the skin for blood oxygen detection.

As an extension of the functions of the hand-worn blood vessel hardness tester in this embodiment, a 3D sensor for step counting (not shown in the figure) is also provided in the base 200 . In this way, when walking or exercising while wearing the blood vessel hardness tester, the blood vessel hardness tester can measure the number of steps, mileage, and calories consumed, thereby helping the user to analyze the exercise situation. Of course, other functions can also be extended to the hand-worn blood vessel hardness tester, such as sleepy eye monitoring, time display and so on.

In the present invention, the use process of the hand-worn blood vessel hardness tester is as follows: when in use, first wear the blood vessel hardness tester on the wrist, turn the knob 760 to drive the slide seat 600 to move in the fixed seat 500, and the first on the panel The indicator light 222 turns red, and the pressure sensor 300 at the bottom of the base 210 moves accordingly to automatically search for the radial artery at the wrist. When the pressure sensor 300 receives the pressure wave of the radial artery, the first indicator light 222 changes from red to green Then rotate the knob 760 so that the pressure sensor 300 is driven by the transmission assembly 700 to press the radial artery downward. When the radial artery is pressed to a specified strength, the second indicator light 223 changes from red to green. At this time, stop rotating the knob 760. Start to detect the hardness of the blood vessel. When the detection is completed, the detection result will be displayed on the liquid crystal display 400 . Turn the knob 760 in the opposite direction, and the pressure sensor 300 will be reset under the drive of the transmission assembly 700 . When the hand-worn blood hardness tester is realizing its extended functions, such as using the ECG detection conductive sheet 230 for heart rate detection and ECG monitoring, or using the blood oxygen detection sensor 240 for blood oxygen detection, or using the 3D sensor for step counting. When analyzing the exercise records, the results can be displayed on the liquid crystal display 400 .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
