[0076] In other embodiments, the stethoscope may alternatively be wirelessly connected to the smartphone. For example, the pulse sound signal is transmitted to the smartphone by using Bluetooth.

[0077] Functions such as storage, processing, operation, and displaying of the terminal device in the embodiments may all be implemented by an application (APP) installed in the terminal device.

[0078] A process of using the blood pressure measuring equipment in the embodiments is as follows:

[0079] First, the headphone plug of the stethoscope is plugged into the smartphone during use. A measuring process of the sphygmomanometer is the same as that of an ordinary sphygmomanometer. The sphygmomanometer controls inflation and deflation. The stethoscope is fixed inside the cuff bladder of the sphygmomanometer and is closely attached to a brachial artery to collect an auscultatory sound (a pulse sound). The APP in the smartphone is started. An operating interface of the APP is shown in FIG. 8. The camera on the smartphone is aligned with a display screen of the electronic sphygmomanometer and starts recording an image on the display screen of the sphygmomanometer and a sound in the stethoscope during blood pressure measurement. The APP in the smartphone processes image data and sound data, for example, displays the amplitude of the strength of the sound, obtains a pressure reading according to image identification, and further determines the blood pressure.

[0080] The APP in the smartphone may further perform further data analysis: displaying the sound data and the pressure image signal on a same timeline. As shown in FIG. 8, a vertical line 14 on the left of the figure marks a time point that corresponds to a systolic pressure and is determined according to an auscultatory method. A vertical line 15 on the right of the figure marks a time point corresponding to a diastolic pressure. Therefore, images that can correspond to the time point and pressure values displayed on the images are the systolic pressure and the diastolic pressure. When the data is played back, a vertical line 16 in the middle moves with a playing progress of the sound. An amplitude curve of the strength of the sound that the vertical line 16 passes through helps the user more accurately determine the sound heard by ears.

[0081] A graphical audio signal of the APP may be in a time domain, or in a frequency domain, or both. The graph is not limited to a line graph, and may be a bar graph or the like. It may be further set that operations such as pausing, continuing, and setting of loop playback between two time points can be performed at any time in a playback process of the sound.

[0082] In addition, the user may manually determine, based on a result that the APP graphically displays the pulse sound data and the pressure image signal on a same timeline, the blood pressure value by using the auscultatory method. The APP may alternatively calculate, according to the pressure data, the blood pressure value by using the oscillometric method. Parameters (for example, C1 and C2 in an amplitude parameter method) used in the oscillometric method may be directly adjusted by using an operating interface (not shown). For ordinary users, it may be set, for measurement at a time, to input a blood pressure value determined to be accurate (for example, the blood pressure value manually determined by using the auscultatory method). An exclusive APP is used to compare the input blood pressure value with a blood pressure value determined by using the oscillometric method and adjust the parameters according to a comparison result, so that the parameters can be simply adjusted without professionals. Alternatively, parameters (for example, C1 and C2) used in the oscillometric method may be automatically calibrated based on the blood pressure value determined by using the auscultatory method. This calibration may be set to be periodic, for example, set to automatic calibration after a time period or times. Parameter modification is calibration for an individual situation, so that the measurement precision is generally higher than a direct reading on an ordinary electronic sphygmomanometer. In addition, after the calibration, a relatively accurate blood pressure value can be obtained without using the stethoscope (the auscultatory method is not used to determine the blood pressure value).

[0083] Implementations of the foregoing interface functions all fall within the scope that can be implemented in the prior art. In the premise of data sources, manners of data processing and displaying, for example, data correlation analysis, and addition of dynamic elements into images are various, and design or improvement can be further performed according to actual requirements.

[0084] During use, the blood pressure measuring equipment in the embodiments is the same as the ordinary electronic sphygmomanometer. Only one click is required to start. The sphygmomanometer automatically performs inflation and deflation to the cuff bladder and synchronously records measured data. After measurement, a blood pressure value determined by using the oscillometric method and/or the auscultatory method is automatically displayed. Alternatively, the recorded pressure image signal (or the pressure data) and sound data may be played back on the terminal device (for example, the smartphone in the embodiments), to manually determine the blood pressure value by using the auscultatory method.

[0085] The foregoing describes the preferred specific embodiments of the present invention in detail. It should be understood that a person of ordinary skill in the art can make many modifications and changes according to the concepts of the present invention without creative efforts. Therefore, any technical solution obtained by a person skilled in the art through logical analysis, reasoning, or limited experiments based on the prior art and according to the concepts of the present invention shall all fall within the protection scope determined in the claims.
