[0025] Embodiment 1:

[0026] As Figure 1 shown, this embodiment provides a full-time blood pressure detection device, including a photoplethysmogram device and a pressure pulse wave device. The photoplethysmogram device is a wearable device such as a ring, bracelet, or watch with a photoplethysmogram sensor. In this embodiment, a ring is taken as an example for detailed analysis. When the user wears the ring 1 on the finger, the blood pressure measurement value at the user's finger can be collected through the photoplethysmogram sensor; the pressure pulse wave device is a cuff blood pressure monitor 2, and the blood pressure measurement value of the user's brachial artery can be collected through the cuff blood pressure monitor 2;

[0027] In this embodiment, in order to facilitate the coordinated use of the ring 1 and the cuff blood pressure monitor 2, the ring 1 and the cuff blood pressure monitor 2 are combined by magnetic attraction. Specifically, a magnetic attraction element 3 is provided on the ring. The magnetic attraction element can be a magnet or a magnetic ring, etc., and the ring is fixed on the cuff blood pressure monitor 2 through the magnetic attraction element.

[0028] In another implementation of the present application, a first magnet 301 is provided on the ring 1, and a second magnet 302 is provided on the cuff blood pressure monitor 2. Magnetic attraction elements are provided on both the ring 1 and the cuff blood pressure monitor 2. Therefore, the ring 1 and the cuff blood pressure monitor 2 can be well fixed. In order to make the ring 1 better fixed on the cuff blood pressure monitor 2, an installation groove for accommodating the ring 1 can be provided on the cuff blood pressure monitor 2, and the ring 1 is placed in the installation groove by magnetic attraction, and the fixing effect is better.

[0029] As Figures 2 - 3As shown, in order to achieve the charging and communication connection between the cuff blood pressure monitor 2 and the ring 1, in this embodiment, a metal probe 201 is provided on the cuff blood pressure monitor, and a metal contact 101 electrically connected to the metal probe 201 is provided on the ring 1. During use, the metal probe 201 can contact the metal contact 101 to achieve electrical connection. The metal probe 201 and the metal contact 101 belong to a contact connection.

[0030] A wireless charging module is provided on the cuff blood pressure monitor 2. The wireless charging module includes a wireless charging transmitting coil and a circuit board for power conversion. The ring 1 further includes a receiving coil and an overvoltage protection element. The battery in the ring 1 can be charged through the wireless charging module. Specifically, when the ring 1 is close to the cuff blood pressure monitor 2 until the receiving coil on the ring 1 is in the changing magnetic field generated by the wireless charging transmitting coil of the cuff blood pressure monitor 2, an induced electromotive force is generated in the receiving coil by the changing magnetic field, and the induced electromotive force drives the current to flow, thereby achieving charging for the ring 1.

[0031] As Figure 4 As shown, in the block diagram of the photoplethysmograph device for measuring blood pressure according to an exemplary embodiment, various modules for performing various functions of obtaining blood pressure measurement values and the connection relationships are configured in the photoplethysmograph device 1. Taking the ring as an example, it includes a PPG (photoplethysmography) signal acquisition module, a photoplethysmography microcontroller unit, a photoplethysmography signal processing module, a power module, a photoplethysmography charging module, a photoplethysmography transmission module, and a photoplethysmography storage module. Among them, the PPG signal acquisition module is used to acquire the blood pressure measurement signal at the user's finger. By emitting a light beam from an LED to irradiate the finger and using a photodetector to measure the intensity of the light passing through or reflected from the skin, the blood pressure measurement signal can be obtained. The photoplethysmography microcontroller unit is used to control each module and process and calculate the data. The power module is responsible for supplying power to the entire system. The photoplethysmography storage module is used to store the blood pressure calibration value of the brachial artery transmitted by the pressure pulse device. The photoplethysmography charging module can be connected to the cuff blood pressure monitor through metal contacts and metal probes to charge the photoplethysmograph device. The photoplethysmography signal processing module is used to convert, analyze, and process the acquired blood pressure measurement signal at the finger to calculate the current blood pressure measurement value.

[0032] As Figure 5As shown, a block diagram of a cuff blood pressure monitor according to an exemplary embodiment, various modules for performing various functions of obtaining the blood pressure value of the brachial artery and the connection relationships are configured in the cuff blood pressure monitor. In this embodiment, the cuff blood pressure monitor can collect pressure pulse signals. The cuff blood pressure monitor includes: a pressure pulse wave microcontroller unit, a pressure pulse wave signal processing module, a pressure pulse wave signal acquisition module, a pressure pulse wave inflation module, a pressure pulse wave deflation module, a pressure pulse wave display module, a pressure pulse wave storage module, a pressure pulse wave button module, and a pressure pulse wave data transmission module. Among them, the pressure pulse wave microcontroller unit is used to control each peripheral module and perform arithmetic processing. The pressure pulse wave inflation module is used to start the air pump to inflate and pressurize the cuff. The pressure pulse wave deflation module is used to enter the measurement stage to deflate the cuff after the pressurization ends. The pressure pulse wave signal processing module is used to collect the pressure signal in the cuff. The pressure pulse wave signal processing module is used to process the collected pressure signal in the cuff, extract the pulse signal therein, and analyze and process the pulse signal to obtain the blood pressure calibration value of the user's brachial artery. The pressure pulse wave display module is used for the display during the measurement process, the display of the measurement results, and the display of setting time parameters, etc. The pressure pulse wave storage module is used to store the blood pressure calibration value of the user's brachial artery and the set measurement parameters. The button module is used to operate the start and stop of the cuff blood pressure monitor, read the memory value, set user information and parameters, etc. The pressure pulse wave data transmission module is used to be electrically connected to the photoplethysmogram device through metal probes and metal contacts.

[0033] Embodiment 2:

[0034] In this embodiment, this embodiment takes a ring as an example for detailed analysis. When the user wears the ring on the wrist, the blood pressure measurement value at the user's finger can be collected through the photoplethysmography sensor. The difference from Embodiment 1 is that in order to ensure the stability of the installation of the ring and the cuff blood pressure monitor, a buckle and a engaging part that can be buckled are respectively provided on the bracelet and the cuff blood pressure monitor. For example, a buckle structure is provided on the ring, and an engaging part is provided on the cuff blood pressure monitor. The engaging part can be a card slot. In the assembled state of the ring and the cuff blood pressure monitor, the buckle on the ring is engaged in the engaging part on the cuff blood pressure monitor. In another embodiment of the present application, the engaging part is two oppositely arranged buckles. When the ring 1 is placed in the engaging part, the two oppositely arranged buckles can be stuck in the inner ring of the ring 1 to realize the assembly of the ring 1 and the cuff blood pressure monitor.
