It usually consists of a pressure measuring device, a cuff, and a display or recording component. When working, the cuff is inflated and pressurized to block the blood flow in the artery, and then slowly deflated. The sensor senses the pressure changes in the blood vessels and converts them into readable values ​​or signals. Whether it is in medical institutions assisting doctors in diagnosing diseases or in daily health monitoring at home, it plays an extremely critical role, helping people to understand their blood pressure status in a timely manner, so as to effectively prevent and manage cardiovascular diseases such as hypertension.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example, using Figure 1-6 A blood pressure meter module according to one embodiment of the present invention is described as follows.

[0018] like Figure 1-5 As shown in the figure, a blood pressure meter module of the present invention includes an air pump motor, the outer surface of the air pump motor 1 is fixedly connected to a base 3, and the outer surface of the base 3 is threadedly connected to a motor screw 2. A PCB component unit 14 is fixedly connected to the top of the base 3, a solenoid valve skeleton 4 is placed on the base 3, and a solenoid valve coil 5 is sleeved on the outer surface of the solenoid valve skeleton 4. An eccentric wheel 6 is fixedly connected to the output end of the air pump motor, and a rocker 7 is hingedly connected to the end of the eccentric wheel 6 away from the air pump motor 1. A leather wrist bracket 8 is fixedly connected to the outer surface of the rocker 7, and a leather wrist 9 is placed on the inner wall of the leather wrist bracket 8. A valve pressure plate 10 is fixedly connected to the outer surface of the leather wrist bracket 8, and a rubber valve sheet 11 is inserted into the inner wall of the valve pressure plate 10. The side of the valve pressure plate 10 away from the leather cup bracket is fixedly connected to the pump head cover 12, and the outer surface of the pump head cover 12 is connected to the pump body screw 13.

[0019] When measuring blood pressure, there are processes of inflation, pressure maintenance and deflation. When inflating, when the sphygmomanometer starts to measure blood pressure, the air pump motor 1 is stably mounted on the base 3 and starts to operate under the fixation of the motor screw 2. The rotation of the motor drives the eccentric wheel 6 to rotate, and the eccentric wheel 6 pushes the rocker 7 to do reciprocating motion.

[0020] In the pump body, the pump head cover 12 and the pump body screws 13 fit tightly together to form a relatively closed space. As the rocker 7 reciprocates, the gas is sucked in and compressed. At the same time, the solenoid valve coil 5 controls the valve on the solenoid valve frame 4 to open, and the gas passes through the rubber valve sheet 11 and the valve pressure plate 10 and flows to the leather wrist 9 through the five-way 143. The leather wrist bracket 8 is used to support the leather wrist 9 to ensure that the leather wrist 9 can expand normally during the inflation process. Among them, the motor assembly 141 in the PCB assembly controls the operation of the air pump motor 1, adjusts the speed and amount of inflation, and gradually increases the pressure in the leather wrist 9 until it is sufficient to block the arterial blood flow.

[0021] During the process of maintaining the pressure, the pressure in the leather wrist 9 is monitored in real time by the sensor 145. When the pressure reaches a level that can block the blood flow in the artery, the sensor 145 transmits a signal to the control unit of the PCB assembly. At this time, the air pump motor 1 may adjust the speed or stop working according to the feedback signal to maintain the pressure in the leather wrist 9 stable.

[0022] During the pressure stabilization stage, the sensor 145 starts to accurately measure the blood pressure. The pressure changes caused by the blood flow on the blood vessel wall are transmitted to the sensor 145 through the wristband 9. The sensor 145 converts the pressure signal into an electrical signal, which is then processed and analyzed by the PCB assembly to obtain the blood pressure value and related data, such as systolic pressure and diastolic pressure.

[0023] Finally, when the blood pressure measurement is completed, the deflation valve assembly 142 in the PCB assembly starts to work. The deflation valve assembly 142 controls the solenoid valve coil 5 to change the state of the valve on the solenoid valve frame 4, so that the gas in the wristband 9 is discharged through the five-way 143 and the deflation valve assembly 142.

[0024] During the deflation process, the leakage valve assembly 144 plays a role in controlling the speed of gas discharge so that the pressure in the wristband 9 drops steadily. The sensor 145 continuously monitors the data changes during the pressure drop process, and can also obtain more information about the elasticity of the blood vessels. The entire deflation process proceeds in an orderly manner until the wristband 9 returns to its initial state and is ready for the next measurement.

[0025] The solenoid valve skeleton 4 can be embedded into the inner wall of the base 3 through the top of the base 3, the air pump motor 1 is fixed to the base 3 through the motor screws 2, and the pump head cover 12, the valve pressure plate 10 and the leather wrist bracket 8 are fixed to each other through the pump body screws 13.

[0026] like Figure 6 As shown, the PCB component unit 14 includes a top plate 146, the top plate 146 is fixedly connected to a sensor 145, the outer surface of the sensor 145 is fixedly connected to a five-way valve assembly 143, a side of the five-way valve 143 close to the sensor 145 is fixedly connected to a leakage valve assembly 144, the outer surface of the five-way valve 143 is fixedly connected to an air release valve assembly 142, and one end of the five-way valve 143 close to the air release valve assembly 142 is fixedly connected to a motor assembly 141.

[0027] The bottom of the top plate 146 is fixedly connected to the top of the base 3 .

[0028] The sensor 145 , the air relief valve assembly 142 , and the leakage rate valve assembly 144 are all fixedly connected to the five-way valve 143 through an air pipe.

[0029] The specific workflow is as follows: During operation, blood pressure measurement is divided into inflation maintenance and deflation states. After the sphygmomanometer is started, the air pump motor 1 starts to operate under the fixation of the motor screw 2. The motor drives the eccentric wheel 6 to rotate, and the eccentric wheel 6 makes the rocker 7 reciprocate. In the pump body part, the pump head cover 12 and the pump body screw 13 seal the pump body space. As the rocker 7 moves, the gas is sucked in and compressed. At the same time, the solenoid valve coil 5 controls the solenoid valve skeleton 4 to open the valve. The gas passes through the rubber valve sheet 11 and the valve pressure plate 10, and enters the leather wrist 9 through the five-way 143. The leather wrist bracket 8 supports the leather wrist 9. In this process, the motor assembly 141 in the PCB assembly controls the air pump motor 1 to adjust the inflation speed and amount, so that the pressure in the leather wrist 9 rises. After the pressure in the leather wrist 9 rises to a level that can block the arterial blood flow, the pressure is monitored by the sensor 145. The sensor 145 transmits a signal to the PCB assembly, and the air pump motor 1 may adjust the speed or pause to maintain the pressure in the leather wrist 9 stable. At this time, the pressure change caused by the blood flow is transmitted to the sensor 145 through the wristband 9. The sensor 145 converts the pressure signal into an electrical signal, which is processed and analyzed by the PCB component to obtain the blood pressure value. After the measurement is completed, the air release valve component 142 in the PCB component works to control the solenoid valve coil 5 to change the valve state of the solenoid valve frame 4. The gas in the wristband 9 is discharged through the five-way 143 and the air release valve component 142. During the discharge process, the leakage valve component 144 controls the gas discharge speed to allow the pressure in the wristband 9 to drop steadily until it returns to the initial state and is ready for the next measurement.
