Wrist strap type physiological information monitoring device

Abstract

The invention provides a wrist strap type physiological information monitoring device which comprises a device body and a wrist strap enabling the device body to be fixed on the wrist portion of a user. A circumferential adjusting mechanism is arranged on the wrist strap, and the circumferential adjusting mechanism is used for adjusting the position of a physiological signal monitoring unit in the length direction of the wrist strap to enable the physiological signal monitoring unit to be opposite to the radial artery of the wrist of the user when the user wears the wrist strap type physiological signal monitoring device on the wrist to conduct physiological signal monitoring. According to the wrist strap type physiological information monitoring device, the physiological signal monitoring unit can align with the radial artery of the wrist of the user, and the fitting degree of the physiological signal monitoring unit and the radial artery of the wrist of the user can further be improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a wristband type physiological information monitoring device. Background technique [0002] The wristband-type physiological information monitoring device is a watch-type physiological monitor. By wearing it on the wrist, the user can not only keep time, but also monitor human physiological parameters such as heart rate fluctuations and blood oxygen in daily activities. Monitor your own health status, so as to take timely first aid measures in case of sudden illness. [0003] For example, if figure 1 As shown, the Chinese utility model patent with the authorized announcement number CN 202171725U discloses a schematic diagram of the appearance of a watch capable of measuring pulse conditions. A wrist watch capable of measuring pulse conditions includes a dial 1 and a strap 2 . A timing unit, a pulse signal processing unit, a video signal processing unit an...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned wristwatch that can measure the pulse condition can both time and monitor the heart rate of the user, since the position of the PVDF piezoelectric film on the back of the dial 1 or the strap 2 is fixed, when the user wears the wristwatch on the wrist , the PVDF piezoelectric film cannot be moved along the length and radial direction of the wrist, so it cannot be solved that the PVDF piezoelectric film cannot be aligned with the radial artery of the user's wrist and the PVDF piezoelectric film cannot be in contact with the skin at the radial artery of the user's wrist fit problem

[0005] For example, if the position on the user's wrist that is convenient for checking the time (generally located in the middle of the user's wrist on the same side as the back of the hand) and the radial artery (generally located on the opposite side of the user's wrist and the back of the hand, and the position that is biased towards the thumb) When the distance between them is different from the distance between the dial 1 and the PVDF piezoelectric film on the watch, when the user wears the watch on the wrist, it will inevitably cause the following problems, that is: if the user sets the dial 1 on the wrist If the user puts the PVDF piezoelectric film on the radial artery of the user’s wrist, the dial 1 cannot be placed on the user’s wrist. A convenient location to check the time

Therefore, the PVDF piezoelectric film cannot be moved along the length of the wrist, not only the PVDF piezoelectric film may not be aligned with the radial artery of the user's wrist, thereby reducing the detection accuracy of the PVDF piezoelectric film, but also reducing the user's use convenience and comfort

[0006] For another example, if the length of the watch strap 2 does not match the size of the user's wrist and the softness of the material of the watch strap 2 is relatively poor, then it is easy for the watch strap 2 to rotate relative to the wrist and the PVDF piezoelectric film to contact the user's wrist. The skin does not fit at the radial artery

Therefore, the PVDF piezoelectric film cannot be moved in the radial direction of the wrist, which reduces the fit between the PVDF piezoelectric film detection and the radial artery of the user's wrist, thereby reducing the accuracy of the PVDF piezoelectric film detection
