Blood Pressure Monitor

The present invention relates to an electronic sphygmomanometer, and more particularly to an electronic sphygmomanometer capable of shortening the time required for blood pressure measurement.

With the development of human civilization, people pay more and more attention to health problems. Many people track their physical condition through various health checks. Among them, blood pressure measurement is indispensable in health checkup. In the project, many diseases can be seen by the level of blood pressure. Therefore, in order to accurately measure blood pressure, an electronic blood pressure monitor has emerged, which not only increases the accuracy of blood pressure measurement, but also because of its easy operation. The measurement of blood pressure is quickly popularized.

In general, the measurement method of the electronic sphygmomanometer is to measure the blood pressure value by Measuring While Drilling (MWD), and the downward measurement method is to press the pressure cuff sleeve to the maximum pressure once by using a pressurizing motor. The value is then released through a deflation valve at a fixed speed. At the same time as the pressure is released, the pressure sensor measures and collects a plurality of pressure point values in the cuff sleeve to calculate the pressure point. Systolic pressure and diastolic blood pressure.

However, in order to calculate the systolic pressure value and the diastolic pressure value more accurately, the pressure sensor must collect more pressure point values when the pressure changes, so the pressure of the pressure relief valve must be slowed down. The pressure sensor has more time to measure and collect the pressure point value, that is, if the pressure of the pressure relief valve is slower, the blood pressure value calculated by the electronic blood pressure monitor is more accurate, so that the length is not only elongated The time of the health check reduces the efficiency of the medical unit.

Therefore, is there an electronic sphygmomanometer that can shorten the time of blood pressure measurement, and It is able to maintain the accuracy of its measurement and thus improve the efficiency of medical consultation.

This creation relates to an electronic sphygmomanometer, particularly an electronic sphygmomanometer capable of shortening the time required for blood pressure measurement.

According to one aspect of the present invention, an electronic sphygmomanometer controls the pressure and pressure release rate of a piezoelectric driving unit according to a pressure change state by a control unit, so as to shorten the time for measuring blood pressure and improve the efficiency of measuring blood pressure. .

According to an embodiment of the present invention, the electronic sphygmomanometer comprises a pulse pulsing unit, a piezoelectric driving unit, a control unit and a pressure sensing unit. The cuff unit contacts the subject's body to measure the blood pressure value of the subject. The piezoelectric driving unit is connected to the pulsation unit for pressurizing and depressurizing the embossing unit.

Figure 1 is a schematic diagram of the electronic blood pressure monitor of the present invention.

Please refer to Figure 1, which is a schematic diagram of the electronic blood pressure monitor of the present invention. In one embodiment, the electronic sphygmomanometer measures at least one blood pressure value of a subject, and includes a vascular unit 10, a piezoelectric driving unit 12, a control unit 14, and a pressure sensing unit 16.

In this embodiment, the cuff unit 10 can be a measurement cuff and directly contact any pulse on the body of the subject to sense the pulse to perform the blood pressure value on at least one artery of the subject. The blood pressure value may be a systolic blood pressure value or a diastolic blood pressure value of the arterial blood vessel, and the vascular pressure unit 10 has an effect of decompressing by inflation or by exhausting the exhaust gas.

The piezoelectric driving unit 12 is connected to the cuff unit 10 for performing inflation and pressure and exhaust pressure relief on the cuff unit 10.

The control unit 14 is electrically connected to the piezoelectric driving unit 12 for controlling the pressure and pressure relief rate of the piezoelectric driving unit 12 according to a preset measurement rule, wherein the preset measurement rule further includes In addition to controlling the piezoelectric driving unit 12, the control unit 14 has a function of calculating and storing the blood pressure value, and further, the function of calculating and storing the blood pressure value. The control unit 14 can be a Micro Controller Unit (MCU).

The pressure sensing unit 16 is electrically connected to the vascular unit 10 and the control unit 14 , which collects a plurality of pressure point values by measuring a pressure change in the vascular unit 10 and transmits the pressure point values. To the control unit 14.

When the blood pressure meter measures the blood pressure, the control unit 14 first inflates and presses the cuff unit 10 through the piezoelectric driving unit 12, and presses the cuff unit 10 in the inflating to press the subject. The arterial blood vessels are completely occluded to the arterial blood vessels, that is, the arterial blood vessels are unable to circulate blood only by intravascular pressure.

Because the arterial blood vessel is compressed by the cuff unit 10 during continuous inflation and pressure, the pressure of the arterial blood vessel is pressed by the pressure of the cuff unit 10 to generate a change in pressure, and the pressure sensing unit 16 collects each The pressure point value is transmitted to the control unit 14 , and the control unit 14 correspondingly records the pressure value of the pulse driving unit 10 by the piezoelectric driving unit 12 The value of the pressure point, and when the value of the pressure point in the arterial blood vessel begins to increase sharply, the control unit 14 will increase rapidly at the pressure. In the interval, a systolic pressure reference value is calculated according to the value of each pressure point. Conversely, when the value of the pressure point in the arterial blood vessel begins to decrease sharply, the control unit 14 also according to each of the intervals in which the pressure is sharply reduced. The pressure point value calculates a diastolic pressure reference value.

However, because the process speed of the continuous inflation and pressurization is fast, the pressure sensing unit 16 cannot directly measure the correct systolic pressure value and the diastolic pressure value, resulting in the systolic pressure reference value and the diastolic pressure reference value. There is usually an error of plus or minus 10 percentage (%) between the actual systolic pressure value and the diastolic pressure value. Therefore, the control unit 14 calculates and defines the systolic pressure reference value by 10 according to the systolic pressure reference value. The error range of % and 10% reduction is a systolic pressure measurement area to indicate that the correct systolic pressure value will be within the systolic pressure measurement area, and the systolic pressure reference is calculated and defined according to the diastolic pressure reference value. The error range of 10% increase and 10% decrease is a diastolic pressure measurement area to perform more accurate blood pressure measurement on the systolic pressure measurement area and the diastolic pressure measurement area.

Wherein, the value of the systolic pressure reference value increased by 10% is an upper limit value of the systolic blood pressure measurement area, and the value of the systolic pressure reference value increased by 10% is the lower limit value of the systolic pressure measurement area; The value of the diastolic pressure reference value increased by 10% is an upper limit value of the diastolic blood pressure measurement area, and the value of the diastolic reference value increased by 10% is the lower limit value of the diastolic blood pressure measurement area.

It is noted that the continuous boosting of the preset measurement rule is when the piezoelectric driving unit 12 inflates and pressurizes the cuff unit 10 until the artery of the subject is completely blocked. The control unit 14 instructs the piezoelectric driving unit 12 to continue to inflate and pressurize to the cuff unit 10 with a boost value, wherein the boost value is when the cuff unit 10 is completely closed. A fixed percentage of the pressure value.

After the pressurization is completed, the control unit 14 instructs the piezoelectric driving unit 12 to quickly depressurize the cuff unit 10 to rapidly reduce the pressure value of the cuff unit 10 to the upper limit value of the systolic pressure measurement area. When the pressure value of the venous pressure unit 10 drops to the upper limit value of the systolic pressure measurement area, that is, the pressure value in the vascular pressure unit 10 has entered the systolic pressure measurement area, The control unit 14 controls the piezoelectric driving unit 12 to slow down the pressure release speed of the pressure pulse unit 10 according to the damping pressure of the preset measurement rule, so that the pressure in the pressure pulse unit 10 is slowly decreased. The pressure sensing unit 16 is capable of accurately measuring the values of each of the pressure points.

When the pressure in the venous unit 10 drops to the lower limit of the systolic pressure measurement area, that is, when the pressure in the vascular unit 10 will leave the systolic pressure measurement area, the control unit 14 will The increased pressure relief of the preset measurement rule controls the piezoelectric driving unit 12 to quickly relieve pressure to the cuff unit 10 until the pressure value of the cuff unit 10 drops to the diastolic pressure measurement area. The upper limit value, that is, when the pressure value of the vascular unit 10 enters the diastolic pressure measurement area, the control unit 14 again instructs the piezoelectric drive unit 12 according to the mitigation pressure of the preset measurement rule. The speed of the pressure relief is again slowed down so that the pressure within the vascular unit 10 can be slowly lowered for the pressure sensing unit 16 to measure and collect the pressure point values.

When the pressure in the cuff unit 10 drops to the lower limit of the diastolic pressure measurement area, that is, when the pressure value of the cuff unit 10 will leave the diastolic pressure measurement area, the control unit 14 is again The increased pressure relief of the preset measurement rule controls the piezoelectric driving unit 12 to quickly relieve the pressure of the cuff unit 10 to the end of the measurement.

In summary, the electronic sphygmomanometer of the present invention has different pressure relief speeds in different blood pressure change intervals, so that the pressure sensing unit 16 can accurately collect and provide the control unit 14 to calculate the systolic pressure value and The value of each pressure point of the diastolic pressure value and the effect of shortening the detection time.

Therefore, compared with the conventional electronic sphygmomanometer, the creation of the control unit can shorten the time required for measuring blood pressure during the health check, thereby improving the efficiency of the medical unit.

However, the above descriptions are only preferred embodiments of the present invention. When it is not possible to limit the scope of implementation of this creation, any changes and modifications that are apparent to those skilled in the art will be considered as not Deviate from the essence of this creation.
