[0002] In traditional pulse diagnosis, doctors diagnose diseases by touching the patient's pulse. This method relies on the doctor's experience and subjective judgment, and there are certain errors and uncertainties. With the development of science and technology, in order to improve the accuracy and objectivity of pulse diagnosis, researchers have combined modern electronic technology with traditional Chinese medicine pulse diagnosis and developed a pulse diagnosis instrument. This instrument can objectively and quantitatively analyze pulse signals, providing doctors with more accurate diagnosis and treatment basis.

[0037] When using the detection device of the pulse diagnosis instrument to perform factory inspection on the pulse diagnosis instrument, the tracheal interface of the pulse diagnosis instrument is connected to the pressurized airbag of the pulse diagnosis instrument, and the detection device is connected to the pulse diagnosis instrument for communication, so that the pulse diagnosis instrument can be easily inspected, which greatly improves the detection efficiency and the factory efficiency of the pulse diagnosis instrument.

[0038] Refer to the following Figure 1 and Figure 2 The detection device of the pulse diagnosis instrument of the present invention is introduced. Figure 1 It is a structural schematic diagram of a detection device of a pulse diagnosis instrument according to an embodiment of the present invention; Figure 2 The present invention is a schematic diagram of the connection structure between the detection device of the pulse diagnosis instrument and the pulse diagnosis instrument according to an embodiment of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the detection device 1 of the pulse diagnosis instrument of the present invention includes a housing 11, on which are arranged a pulse diagnosis instrument tracheal interface 111, a barometer tracheal interface 112, a computer communication interface 113, and a display screen 114 and a button 115 used as a human-computer interaction component. A first air pump 12, a first pressure relief solenoid valve 13, an air pressure sensor 14, and a circuit board 15 as a microcontroller are arranged in the housing 11. The exhaust port of the first air pump 12 is connected to the inner end of the pulse diagnosis instrument tracheal interface 111 through a first pipeline 161, the air intake port of the first air pump 12 is connected to the atmospheric environment, the first pressure relief solenoid valve 13 is connected to the first pipeline 161 through a second pipeline 162, the inner end of the barometer tracheal interface 112 is connected to the first pipeline 161 through a third pipeline, and the air pressure sensor 14 is arranged in the first pipeline 161.

[0040] like Figure 2 As shown, the pulse diagnosis instrument 2 includes an annular housing 21, an annular pressurized airbag 22, a pressure sensor 23, a second air pump 24, a second pressure relief solenoid valve 26, a one-way conduction interface 27, a display device (not shown in the figure) and a microcontroller (not shown in the figure). The outer ring of the pressurized airbag 22 is connected to the inner wall of the housing 21, the pressure sensor 23 is connected to the inner ring surface of the pressurized airbag 22, the pressurized airbag 22 is connected to the exhaust port of the second air pump 24 through the sixth pipeline 25, the air intake port of the second air pump 24 is connected to the atmospheric environment, the second pressure relief solenoid valve 26 is connected to the sixth pipeline 25 through a pipeline, the outlet end of the one-way conduction interface 27 is connected to the sixth pipeline 25 through a pipeline, and the one-way conduction interface 27 can only be conducted from its inlet end to the outlet end. The pressure sensor 23, the second air pump 24, the second pressure relief solenoid valve 26 and the display device are connected to the microcontroller through cable communication.

[0041] When the detection device 1 is used to detect the pulse diagnosis instrument 2, the outer end of the pulse diagnosis instrument tracheal interface 111 of the detection device 1 is connected to the inlet end of the unidirectional conduction interface 27 of the pulse diagnosis instrument 2 through the fourth pipeline 164, the outer end of the barometer tracheal interface 112 is connected to the standard barometer 3 through the fifth pipeline 165, and the outer end of the computer communication interface 113 is connected to the computer 4 through a cable. The computer 4 is connected to the microcontroller of the pulse diagnosis instrument 2, so that the detection device 1 is indirectly connected to the microcontroller of the pulse diagnosis instrument 2. The computer 4 can be a desktop computer, a laptop computer, a tablet computer, an industrial computer, etc.

[0042] When detecting the pulse rate accuracy of the pulse diagnosis instrument 2, a support member is arranged in the middle cavity of the pulse diagnosis instrument 2 so that the pressure sensor 23 is pressed against the support member after the pressurized airbag 22 is inflated. The operator sets the frequency setting value through the button 115, and the display screen 114 synchronously displays the frequency setting value. When the chip on the circuit board 15 obtains the set frequency setting value, it controls the first air pump 12 and the first pressure relief solenoid valve 13 to inflate and exhaust the pressurized airbag 22 according to the frequency setting value, so as to simulate the beating of the pulse. In this process, the air pressure sensor 14 detects the air pressure value at the location in real time, the chip on the circuit board 15 obtains the real-time detection value of the air pressure sensor 14 and processes the real-time detection value of the air pressure sensor 14 to obtain the air pressure change frequency, and the chip on the circuit board 15 sends the air pressure change frequency to the computer 4; the pressure sensor 23 of the pulse diagnosis instrument 2 detects the pressure value in real time and sends it to the microcontroller of the pulse diagnosis instrument 2, the microcontroller of the pulse diagnosis instrument 2 processes the detection value of the pressure sensor 23 to obtain the pulse frequency measurement value, and the microcontroller of the pulse diagnosis instrument 2 sends the pulse frequency measurement value to the computer 4; the computer 4 displays the pulse frequency measurement value and the air pressure change frequency through its display, so that the operator can judge the pulse rate accuracy of the pulse diagnosis instrument 2 accordingly. Specifically, when the difference between the pulse frequency measurement value and the air pressure change frequency does not exceed the required range (for example, ±3 times / min), it means that the pulse rate accuracy of the pulse diagnosis instrument 2 meets the requirements, otherwise it means that the pulse rate accuracy of the pulse diagnosis instrument 2 does not meet the requirements.

[0043] When testing the accuracy of pulse pressure, a support is provided in the middle cavity of the pulse diagnosis instrument 2, so that the pressure sensor 23 is pressed against the support after the pressurized airbag 22 is inflated. The operator sets the pressure setting value through the button 115, and the display screen 114 synchronously displays the pressure setting value. When the chip on the circuit board 15 obtains the set pressure setting value, it controls the first air pump 12 to inflate the pressurized airbag 22, or the chip on the circuit board 15 sends an inflation instruction to the microcontroller of the pulse diagnosis instrument 2 through the computer 4 so that the microcontroller of the pulse diagnosis instrument 2 controls the second air pump 24 to inflate the pressurized airbag 22. In the process of inflating the pressurized airbag 22, the chip on the circuit board 15 controls the air pressure sensor 14 to detect the air pressure value at the location in real time; when the detection value of the air pressure sensor 14 reaches the pressure setting value, the inflation of the pressurized airbag 22 is stopped. At this time, the chip on the circuit board 15 sends an instruction to the computer 4 to obtain the detection value of the pressure sensor 23, and the computer 4 obtains the detection value of the pressure sensor 23 of the pulse diagnosis instrument 2 at this time and displays the detection value of the pressure sensor 23 on its display. The computer 4 can also obtain the pressure setting value from the circuit board 15 and display the pressure setting value on its display. The operator can judge the pulse pressure accuracy of the pulse diagnosis instrument 2 by comparing the pressure setting value with the detection value of the pressure sensor 23.

[0044] When performing the accuracy detection of the applied mechanical quantity, the operator sets the external pressure setting value through the button 115, and the display screen 114 synchronously displays the external pressure setting value. When the chip on the circuit board 15 obtains the set external pressure setting value, the computer 4 sends the instruction of "generating external force according to the external pressure setting value" to the microcontroller of the pulse diagnosis instrument 2 so that the microcontroller of the pulse diagnosis instrument 2 controls the second air pump 24 to inflate the pressurized airbag 22. When the second air pump 24 completes the inflation operation of the pressurized airbag 22, the microcontroller of the pulse diagnosis instrument 2 controls the second air pump to stop inflating. At this time, the chip on the circuit board 15 controls the air pressure sensor 14 to detect the air pressure value at the location. The computer 4 obtains the external pressure setting value and the detection value of the air pressure sensor 14 from the circuit board 15 and displays them on its display. The operator can judge the accuracy of the applied mechanical quantity of the pulse diagnosis instrument 2 by comparing the external pressure setting value with the detection value of the air pressure sensor 14.

[0045] By using the detection device 1 to perform factory inspection on the pulse diagnosis instrument 2, the pulse diagnosis instrument 2 can be easily inspected, which greatly improves the inspection efficiency and the factory delivery efficiency of the pulse diagnosis instrument 2.

[0046] Preferably, when the pulse pressure accuracy is detected, when the air pressure sensor 14 detects the air pressure value at the location in real time, the standard barometer 3 synchronously detects the air pressure value at the location; if there is a large difference between the detection value of the standard barometer 3 and the air pressure sensor 14 (for example, the difference is greater than 0.5pa), the computer 4 obtains the difference and sends the difference to the chip on the circuit board 15, and the chip on the circuit board 15 corrects the real-time detection value of the air pressure sensor 14. "When the detection value of the air pressure sensor 14 reaches the pressure setting value, stop inflating the pressurized airbag 22" specifically means: when the corrected detection value of the air pressure sensor 14 reaches the pressure setting value, stop inflating the pressurized airbag 22. "The computer 4 obtains the detection value of the pressure sensor 23 of the pulse diagnosis instrument 2 at this time and displays the detection value of the pressure sensor 23 on its display" specifically means: the computer 4 obtains the corrected detection value of the pressure sensor 23 of the pulse diagnosis instrument 2 at this time and displays the corrected detection value of the pressure sensor 23 on its display. “The operator can determine the accuracy of the pulse pressure of the pulse diagnosis instrument 2 by comparing the pressure setting value with the detection value of the pressure sensor 23” specifically means: the operator can determine the accuracy of the pulse pressure of the pulse diagnosis instrument 2 by comparing the pressure setting value with the corrected detection value of the pressure sensor 23.

[0047] In this way, the accuracy of the detection device 1 in detecting the pulse pressure accuracy of the pulse diagnosis instrument 2 is further improved.

[0048] It should be noted that the display screen 114 and the button 115 are used as human-computer interaction components, which is only a specific setting method, and can be adjusted in actual applications. For example, the human-computer interaction component can also be a voice broadcast device and a button 115 arranged on the housing 11, or a touch display screen arranged on the housing 11. In addition, the air pressure sensor 14 is arranged in the first pipeline 161, which is also a specific setting method, and can be adjusted in actual applications. For example, the air pressure sensor 14 can be arranged in the second pipeline 162, or in the third pipeline 163, or in two or three of the first pipeline 161, the second pipeline 162, and the third pipeline 163. In addition, the first pressure relief solenoid valve 13 and the second pressure relief solenoid valve 26 can also be replaced by other electrically controlled valves, such as valves driven to open and close by a motor.

[0049] It should also be noted that the computer 4 is communicatively connected with the microcontroller of the pulse diagnosis instrument 2, so that the detection device 1 is indirectly communicatively connected with the microcontroller of the pulse diagnosis instrument 2. This is also a specific setting method, which can be adjusted in actual applications. For example, a pulse diagnosis instrument communication interface can be set on the shell 11, and the inner end of the pulse diagnosis instrument communication interface is communicatively connected with the circuit board 15 of the detection device 1. When the detection device 1 is used to detect the pulse diagnosis instrument 2, the outer end of the pulse diagnosis instrument communication interface is communicatively connected with the microcontroller of the pulse diagnosis instrument 2, so that the detection device 1 is directly communicatively connected with the microcontroller of the pulse diagnosis instrument 2. In addition, a barometer air pipe interface 112 is provided on the shell 11, and the inner end of the barometer air pipe interface 112 is connected to the first pipe 161 through the third pipe. When the detection device 1 is used to detect the pulse diagnosis instrument 2, the outer end of the barometer air pipe interface 112 is connected to the standard barometer 3 through the fifth pipe 165, so as to check the accuracy of the air pressure sensor 14 through the standard barometer 3. This is only a more preferred setting method, which can be adjusted in actual application. For example, in a feasible embodiment, the barometer air pipe interface 112 is not provided on the shell 11.

[0050] In another feasible embodiment, the detection device 1 may further include the standard barometer 3 in the above embodiment.

[0051] In another feasible embodiment, the detection device 1 may also include the computer 4 in the above embodiment, and the computer 4 and the circuit board 15 constitute the controller of the detection device 1. When the computer 4 is configured with a display and an input device, the display and input device of the computer 4 serve as part of the human-computer interaction component of the detection device 1.

[0052] In addition, the present invention also provides a control method for a detection device of a pulse diagnosis instrument. The detection device includes an air pump, a pressure relief electric control valve, an air pressure sensor, a controller, a human-computer interaction component, and an air tube interface of the pulse diagnosis instrument; the exhaust port of the air pump is connected to the inner end of the air tube interface of the pulse diagnosis instrument through a first pipeline, and the outer end of the air tube interface of the pulse diagnosis instrument is used to communicate with the pressurized air bag of the pulse diagnosis instrument, the pressure relief electric control valve is connected to the first pipeline through a second pipeline, and an air pressure sensor is arranged in the first pipeline and / or the second pipeline, and the air pressure sensor, the air pump, the pressure relief electric control valve, and the human-computer interaction component are all connected to the controller in communication, and the detection device can be connected to the pulse diagnosis instrument in communication; when detecting the pulse rate accuracy of the pulse diagnosis instrument, the air pump and the pressure relief electric control valve are used to inflate and exhaust the pressurized air bag respectively to simulate the beating of the pulse.

[0053] like Figure 3 As shown, the control method of the detection device includes:

[0054] Step S100, in the pulse rate accuracy detection mode, obtaining a frequency setting value;

[0055] Step S200: When the frequency setting value is obtained, the air pump and the pressure relief electric control valve are controlled to work alternately, so that the detection value detected by the air pressure sensor changes according to the frequency setting value;

[0056] Step S300, in the process of the air pump and the pressure relief electric control valve working alternately, the pulse rate detection value of the pulse diagnosis instrument is obtained in real time;

[0058] Through such a control method, the pulse rate accuracy of the pulse diagnosis instrument can be conveniently detected, thereby greatly improving the detection efficiency.

[0059] Furthermore, the control method further includes:

[0062] Obtain the detection value of the pressure sensor of the pulse diagnosis instrument;

[0063] The human-computer interaction component is controlled to output the detection value and pressure setting value of the pressure sensor of the pulse diagnosis instrument.

[0064] Through such a control method, the pulse pressure accuracy of the pulse diagnosis instrument can be conveniently detected, which greatly improves the detection efficiency and can avoid the situation where inaccurate inflation pressure leads to inaccurate detection results of the detection device, thereby improving the detection accuracy and reliability of the detection device.

[0065] Preferably, the control method also includes: calculating a frequency error value based on the frequency setting value and the pulse rate detection value and controlling the human-computer interaction component to output the frequency error value; and / or calculating a pressure error value based on the detection value of the pressure sensor of the pulse diagnosis instrument and the pressure setting value and controlling the human-computer interaction component to output the pressure error value.

[0066] Through such a setting, the operator can more intuitively know the accuracy of the pulse diagnosis instrument. It is understandable that the control method may not include "step S400, controlling the human-computer interaction component to output the frequency setting value and the pulse rate detection value" and "controlling the human-computer interaction component to output the detection value of the pressure sensor of the pulse diagnosis instrument and the pressure setting value". Instead, the frequency error value is calculated according to the frequency setting value and the pulse rate detection value and the human-computer interaction component is controlled to output the frequency error value; and / or the pressure error value is calculated according to the detection value of the pressure sensor of the pulse diagnosis instrument and the pressure setting value and the human-computer interaction component is controlled to output the pressure error value.

[0067] Furthermore, the control method further includes:

[0068] In the external mechanical quantity accuracy detection mode, obtain the external pressure setting value;

[0069] When the external pressure setting value is obtained, a command of "generating external pressure according to the external pressure setting value" is sent to the pulse diagnosis instrument;

[0070] After the air pump of the pulse diagnosis instrument completes pressurizing the pressurized air bag of the pulse diagnosis instrument according to the instruction, obtaining the detection value of the air pressure sensor;

[0071] Control the human-computer interaction component to output the detection value of the air pressure sensor and the pressure setting value.

[0072] Through such a setting, the accuracy of the external mechanical quantity of the pulse diagnosis instrument can be easily detected, which greatly improves the detection efficiency and can avoid the situation where the detection result of the detection device is inaccurate due to the error in the pressure sensor when judging the accuracy of the external mechanical quantity by comparing the detection value of the pressure sensor of the pulse diagnosis instrument with the pressure setting value, thereby improving the detection accuracy and reliability of the detection device.

[0073] Preferably, the first pipeline and / or the second pipeline is connected to a standard barometer, and the control method further comprises:

[0074] When the detection value of the air pressure sensor is obtained, the detection value of the standard barometer is obtained;

[0075] The difference between the detection value of the air pressure sensor and the detection value of the standard barometer is calculated and the detection value of the air pressure sensor is corrected accordingly.

[0076] With such an arrangement, in the process of using the detection device to detect the pulse diagnosis instrument, while obtaining the detection value of the air pressure sensor in the detection device, the detection device can synchronously obtain the detection value of the standard barometer at this time. For example, when the standard barometer and the detection device are not communicatively connected, the user is prompted to read and input the detection value of the standard barometer through the human-computer interaction component, or the detection value of the standard barometer is directly read when the standard barometer and the detection device are communicatively connected, and then the difference between the detection value of the air pressure sensor and the detection value of the standard barometer is calculated and the detection value of the air pressure sensor is corrected, so as to obtain a more accurate detection result, thereby improving the detection accuracy of the detection device.

[0077] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
