Background technique

Nowadays, with the further strengthening of our country's national strength, the international recognition of traditional Chinese medicine has been improved. Diagnosing the pulse is a traditional classic treatment method. By grasping the patient's pulse condition, the doctor can give an accurate judgment on the cause of the patient. The pulse signal contains a lot of physiological information, and pulse detection and information analysis are often carried out, which is convenient for early understanding of the changing trend of human physiological health status, so as to prevent and treat diseases early.

With the development of modern electronic science and technology, there have been instruments on the market that utilize circuits to signal the patient's pulse. Using such an instrument, when a doctor diagnoses a patient's condition, the doctor no longer needs to take the pulse himself. But various pulse number instruments on the market can only detect the patient's pulse strength or the patient's pulse frequency. That is to say, the detection amount of the existing pulse signal instrument is generally relatively single.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail. It can be understood that the specific embodiments described here are only used to explain the utility model, rather than limit the utility model. In addition, it should be noted that, for the convenience of description, only the part related to the present utility model is shown in the drawings but not the whole content.

first embodiment

This embodiment provides a technical solution for the control circuit of the pulse meter. Referring to Fig. 1, in this technical scheme, described pulsometer control circuit comprises: pulse sensor 11, pulse intensity detection module 12, pulse frequency detection module 13, camera scanning module 14, touch input module 15, micro control unit (Microcontrol unit, MCU) 16, output module 17.

The pulse sensor 11 is a pressure-sensitive sensor, which can sense the patient's pulse, and output an electrical signal representing the pulse, that is, a pulse signal, according to the pulse.

The pulse intensity detection module 12 is used to detect the intensity of the patient's pulse. Specifically, the pulse intensity detection module 12 detects the intensity of the patient's pulse by detecting the amplitude of the pulse signal. After the pulse intensity detection module 12 completes the amplitude detection of the pulse signal, it outputs the detection result signal to the connected MCU 16 .

The pulse rate detection module 13 is used to detect the pulse rate of the patient per unit time. In other words, the purpose of setting the pulse rate detection module 13 is to detect the patient's pulse rate. Preferably, an analog/digital conversion unit and a counter unit are built in the pulse count detection module 13 . Through the counter unit, the pulse frequency detection module 13 counts the pulse frequency represented by the pulse wave signal within a unit interval, and completes the detection of the patient's pulse frequency.

Similarly, after completing the detection of the patient's pulse rate per unit time, the pulse rate detection module 13 transmits the detection result of the pulse rate to the connected MCU 16 .

The camera scanning module 14 is used to collect facial images of patients. The camera scanning module 14 is respectively connected with a preset camera and the MCU 16 . After receiving the facial image of the patient through the camera connected thereto, the camera scanning module 14 transmits the received facial image to the MCU 16 also connected thereto.

The touch input module 15 is used to receive user's own comfort level input through touch operation through the touch screen. After the touch input module 15 receives the user's touch operation, it transmits the touch signal triggered by the touch operation to the connected MCU 16 .

The MCU 16 is respectively connected with the pulse intensity detection module 12 , the pulse rate detection module 13 , the camera scanning module 14 , the touch input module 15 and the output module 17 . Through the connection with the pulse intensity detection module 12 , the MCU 16 receives the pulse intensity detection result signal of the patient from the pulse intensity detection module 12 . At the same time, through the connection with the pulse intensity detection module 12 , the MCU 16 can send various operation control instructions to the pulse intensity detection module 12 to complete the operation control of the pulse intensity detection module 12 .

In addition, through the connection with the pulse rate detection module 13, the MCU 16 and the pulse rate detection module 13 receive the detection result signal of the patient's pulse rate per unit time. Moreover, the MCU 16 can also send various control instructions to the pulse detection module 13 through the connection with the pulse detection module 13, so as to complete the operation of the pulse detection module 13 control.

Through the intensity of the pulse signal received from the pulse intensity detection module 12, that is, the pulse intensity, and the pulse rate per unit time received from the pulse rate detection module 13, the MCU16 can be preset The program recognizes more than 20 kinds of conventional human pulses, such as floating pulse, sinking pulse, slow pulse, counting pulse, virtual pulse, etc., so as to further judge the user's current health status according to the recognized pulse. It should be noted that the judgments of the above-mentioned various pulse conditions are obtained through comprehensive recognition of the intensity and frequency of pulse signals continuous in time (that is, the number of pulse beats per unit time), so the recognition results are more accurate.

Further, the MCU 16 is also connected to the camera scanning module 14 and the touch input module 15 . Through the connection with the camera scanning module 14 , the MCU 16 can receive the facial image of the user collected by the camera scanning module 14 . The MCU 16 can further run an emotion recognition algorithm to recognize the user's current emotional state based on the facial image, and then provide another kind of reference information for more accurate judgment of the user's health status.

Through the connection with the touch input module 15, the MCU 16 can receive the comfort level characterization signal generated by the user's touch operation. Similarly, the comfort level characterization signal can also be used as a reference information for judging the user's health status.

Since the pulse signal control circuit includes the camera scanning module 14 and the touch input module 15, the MCU 16 can further obtain the user's facial image and the comfort level characterization signal input by the user himself, so that the pulse signal itself can The types of physical quantities to be detected are no longer single. And, thanks to the user's facial image, it is possible to recognize the user's emotional state when the pulse is signaled. Thanks to the comfort level characterization signal input by the user, it is possible to know the comfort level that the user feels when feeling the pulse. Therefore, the MCU 16 can make a more accurate judgment on the user's health status.

The output module 17 is connected to the MCU 16 . The function of the output module is to drive the input device connected to it to output the pulse rate and the intensity of the pulse signal to the user. The output module 17 may be a display module, or a voice prompt module. Moreover, further, the MCU 16 can also be simultaneously connected to two types of output modules 17 , the display module and the voice prompt module.

The display module is used to drive the display device of the pulse meter, so as to display the number of pulse beats and the intensity of the pulse signal to the user in the form of images. Typically, the display device connected to the display module may be a liquid crystal (Liquid crystal display, LCD) display device. The voice prompt module is used to drive the voice output device, so as to output the number of pulse beats and the intensity of the pulse signal to the user in the form of voice.

In this embodiment, a pulse intensity detection module and a pulse frequency detection module are respectively installed in the control circuit of the pulse measuring instrument, so as to realize the simultaneous measurement of the patient's pulse intensity and frequency, and overcome the disadvantages of the single detection amount commonly existing in the existing pulse measuring instruments .

Since the received pulse signal has been converted into a digital signal, the pulse strength detection module 23 and the pulse count detection module 24 are both digital circuit modules, without any analog circuit elements or components.

The memory 29 can be a volatile memory or a non-volatile memory. Whether it is a volatile memory or a non-volatile memory, the MCU 27 should be able to erase and rewrite the data stored in the memory 29 .

The memory 29 is used to store the pacing frequency and the intensity of the pulse signal of a normal person. In this embodiment, after the MCU 27 receives the intensity of the pulse signal detected by the pulse intensity detection module and the pacing times of the pulse signal detected by the pulse frequency detection module within a unit time, Compared with the normal person's pacing frequency and the strength of the pulse wave signal stored in the memory, the health status of the user is judged. For example, if after comparing and judging, it is found that the intensity of the patient's pulse signal exceeds the intensity range of the pulse signal of a normal person, then the MCU 27 can drive an output module such as a voice reminder module to prompt the user to inform the user that the Pay attention to your body in your daily life.

Other modules of this embodiment have the same or similar functions and structures as those of the above embodiments of the present invention, and will not be repeated here.
