In the embodiment of the present application, the micro pump and the pneumatic pressure sensor are disposed in the watch body 302, and the airbag 305 is connected to the watch body 302. The micro pump and the air pressure sensor are integrated in the watch body 302, so that the structure of the air bag 305 is simplified, and a user can wear the blood pressure measuring watch comfortably for a long time. The positions of the micro pump and the air pressure sensor are not limited, and the micro pump and the air pressure sensor can be respectively communicated with the air passage of the air bag 305. In some embodiments, the micro-pump is disposed within the watch body 302 and the air pressure sensor is disposed on the air bag 305. In some embodiments, the micro-pump and the pressure sensor are integrated on the balloon 305.

In addition, in this embodiment, the watchband includes first watchband 301 and second watchband 303 that are located the opposite both ends of table body 302, first watchband 301 and second watchband 303 rotate with table body 302 respectively and are connected, gasbag 305 is located on first watchband 301 or second watchband 303, the tip of first watchband 301 and the tip of second watchband 303 that keep away from table body 302 are equipped with fixing device 304, when the user wears the blood pressure measurement wrist-watch, with table body 302 and user's wrist contact, first watchband 301 and second watchband 303 are crooked and pass through fixing device 304 fixed connection, so that wear the blood pressure measurement wrist-watch in user's wrist. The binding tightness degree of the watchband is adjusted by adjusting the connecting positions of the first watchband 301, the second watchband 303 and the fixing device 304.

The specific structure of the fixing device 304 is not limited, and includes a folding buckle, a pin buckle, a butterfly hidden buckle, and the like that can connect the end of the first band 301 and the end of the second band 303 that are away from the watch body 302.

In the present application, the air bag 305 is detachably mounted on the watchband by the connecting means 306, specifically in the present embodiment, the air bag 305 is detachably mounted on the first watchband 301 by the connecting means 306; in some embodiments, bladder 305 is removably attached to second wristband 303 via attachment device 306. In the embodiment of the present application, taking the case where the air bag 305 is mounted on the first band 301 as an example, the connecting device 306 can limit the relative movement between the air bag 305 and the first band 301 along a transverse direction (shown by an X direction in fig. 3), which is a width direction of the first band 301; when the blood pressure measuring wristwatch is worn, the connecting device 306 allows the end of the air bag 305 away from the watch body 302 and the wristband to be displaced relative to each other in the longitudinal direction of the wristband (indicated by the Y direction in fig. 1) due to the fact that the bending radius of the first band 301 and the bending radius of the air bag 305 do not match.

Since the connecting means 306 is located between the airbag 305 and the first band 301, the blood pressure measuring wristwatch looks beautiful when the user wears the blood pressure measuring wristwatch. The air bag 305 is detachably mounted on the first watchband 301 through the connecting device 306, the connecting device 306 is equivalent to a binding device, when a user wears the blood pressure measuring watch, the air bag 305 is in contact with the wrist of the user, the first watchband 301 and the air bag 305 are bent, the length direction of the first watchband 301 can also be understood as the length direction of the wrist, people around different wrists cause the bending radius of the first watchband 301 and the bending radius of the air bag 305 to be inconsistent, and the connecting device 306 allows the end of the air bag 305 far away from the watch body 302 and the first watchband 301 to generate relative displacement through sliding along the length direction of the first watchband 301.

That is, the air bag 305 and the first band 301 can slide relatively along the direction of the wrist circumference, so that the blood pressure measuring device can be adapted to people around different wrists, and the blood pressure measuring range is wide. In the process that the air bag 305 and the first watchband 301 generate relative movement along the length direction, the micro pump is communicated with the air bag 305 through an air path, and the air pressure sensor is communicated with the air bag 305 through the air path.

Then, after the user wears the blood pressure measuring watch, in the process of measuring the blood pressure, the connecting device 306 restricts the relative movement of the air bag 305 and the first watchband 301 along the transverse direction, i.e. the connecting device 306 restricts the transverse movement (along the arm length direction) of the air bag 305, so as to ensure that the air bag 305 and the first watchband 301 are relatively static along the transverse direction and do not have obvious deviation; when the micro pump is controlled to inflate the inner cavity of the air bag 305, it is ensured that the first watchband 301 can completely restrain the air bag 305 from expanding outwards in the inflating process of the air bag 305, so that the expanding pressure of the air bag 305 completely acts on the wrist inwards, the air bag 305 compresses the blood vessel of the wrist of the user to block the blood flow in the blood vessel, then the blood in the blood vessel flows again when the micro pump deflates the inner cavity of the air bag 305, the vibration change caused by the blood in the process can reflect the blood pressure change in the blood vessel, and the pressure signal of the inner cavity of the air bag 305 detected by the air pressure sensor can be used for measuring the blood pressure. Therefore, the blood pressure measurement precision is effectively ensured.

The relationship between the widths of first band 301 and bladder 305 is not limited, and in some embodiments, the width of bladder 305 is greater than the width of first band 301. In some embodiments, the sum of the thickness of the wristband, the connecting device 306, and the bladder 305 does not exceed the thickness of the watch body 302, and the blood pressure measuring watch is aesthetically pleasing.
