Description
Technical Field
The invention relates to the field of medical instruments, in particular to a human body function state evaluation device.
Background
With the acceleration of life rhythm, the psychological impatience, tension and depression can easily influence the distribution of human blood in various positions of human body. The difference in the upper and lower temperature of the human body is called as the constitution of upper-heat, lower-cold or upper-cold, lower-heat in traditional Chinese medicine. The long-term mental depression of a human body easily causes dysfunction of cerebral cortex, causes a series of pathological changes, relates to vegetative nerves, causes the excitation of vagus nerve function, inhibits the conduction system of the heart, and leads both the myocardial contractility and the conduction speed to be inhibited and interfered. Due to the limitation of the sensitivity of the current sensor, the arrhythmia, the speed and the weakness, the force and the like of the heart cannot be directly observed on the electrocardiogram. The pulse wave is formed by the propagation of the pulsation (vibration) of the heart along the arterial blood vessel and the blood flow to the periphery. The pulse wave can reflect the distribution condition of heart blood in the information of the intensity, the conduction speed and the like of the pulse wave in the human carotid artery, the wrist radial artery and the instep and tibialis anterior artery, and the pulse wave has certain attenuation when being transmitted to the human carotid artery, the wrist radial artery and the instep and tibialis anterior artery, and can reflect the rhythm condition of the heart. The pulse rate and the heart rate have certain difference when pulse waves are transmitted to carotid arteries, radial arteries of wrists and anterior tibial arteries of a human body. When there are some problems in human body functions, for example, there may be some pathological features of asthma, wheezing, shortness of breath, thick breath, and tiny breath in human respiration. At present, western medicine mainly utilizes an electrocardiograph to measure fluctuation information of the heart of a human body, utilizes a stethoscope to sense the change of respiration, and traditional Chinese medicine utilizes a pulse diagnosis instrument to detect wrist radial artery information, and the two methods lack overall understanding of the functional state of the human body, so that a device for overall evaluation of the functional state of the human body is needed in the market.

And a signal processing unit 120 for preprocessing the pressure signal at each fluctuation point. And the evaluation unit 130 is used for evaluating the human body function state according to the processed pressure signal.
It should be noted that the pressure signals in this embodiment include actual static pressure signals and dynamic pressure signals, as shown in fig. 2, the pressure signal acquisition probe in the present invention acquires pressure signals at fluctuation points of different static pressures of a human body in a parallel acquisition manner, that is, the actual static pressure signals and the dynamic pressure signals at the fluctuation points are acquired.

The acquisition method has high pressurization precision, can simultaneously acquire pulse wave signals of 'cun', 'guan' and 'chi' of the wrist of a human body, wherein 12 fluctuation points can be under the same static pressure, then the static pressure at the 12 fluctuation points is integrally and simultaneously changed, or each fluctuation point is respectively under different static pressures, namely the static pressure applied by each bandage corresponding to the 12 fluctuation points can be the same or different, thus more pulse wave detail characteristics are synchronously acquired, pulse condition information of users under different static pressures and dynamic pressures can be effectively and completely given out, the analysis of relevant characteristics of pulse waves under different positions can be realized, and the more comprehensive evaluation of the functional state of the human body can be realized by analyzing the pressure information of each fluctuation point under different static pressures.
It should be further noted that the invention adopts a parallel mode (FPGA) to synchronously acquire the actual static pressure signal and the dynamic pressure signal at the fluctuation point of the human body under different static pressures, so as to realize interaction with a plurality of data, a plurality of dynamic areas designed in the FPGA are independent and parallel to each other, and one dynamic area can realize different acquisition functions, thus realizing synchronous acquisition of a plurality of fluctuation point data, reducing the data acquisition cost and obviously improving the acquisition efficiency. Of course, the acquisition mode is not limited to the parallel acquisition mode, and a serial and serial-parallel mixed acquisition mode may also be adopted, which is not specifically limited herein.
Specifically, as shown in fig. 3, the apparatus further includes a pressurizing unit 140, and the pressurizing unit 140 is configured to apply pressure to the wrist bands 150 at the fluctuation points before or during the pressure signal acquisition of the sensor array 110 to maintain the pressure of each wrist band 150 at a predetermined value. In this embodiment, the pressing unit 140 adopts a band contraction type pressing manner, that is, a band is disposed on the wrist band 150, and the band is tightened or relaxed to press the human body. Compared with the prior art, the pressurizing device does not need to be provided with a related air pressure device such as an air bag and the like, and can achieve the pressurizing effect only by tightening or relaxing the bandage. Of course, it is obvious to those skilled in the art that the mechanical pressing mode, the manual pressing mode or the non-pressing mode may be selected according to actual needs, and is not limited specifically, that is, the pressing unit in this embodiment may also be removed to perform the function of evaluating the function of the human body.
Optionally, as shown in fig. 3, the pressurizing unit 140 in this embodiment includes a pressure sensor 141, a comparing module 142, and a micro motor 143, wherein an output end of the pressure sensor 141 is connected to an input end of the comparing module 142, an output end of the comparing module 142 is connected to an input end of the micro motor 143, and both the pressure sensor 141 and the micro motor 143 are connected to the wristband 150.
It should be noted that, as shown in fig. 3, the pressure sensor 141 in this embodiment may adopt a static pressure sensor, and the specific operation principle is as follows: the micromotor 143 applies pressure to the bandage 150 to tighten the bandage, so as to realize pressurization on the skin surface of the human body through the wrist strap 150, the pressure sensor 141 senses the static pressure applied to the skin surface of the human body through the wrist strap 150, the comparison module 142 compares the pressure signal with the standard pressure stored in advance according to the pressure signal, and realizes feedback control on the micromotor 143 according to the comparison result, and the micromotor 143 rotates to adjust the actual static pressure and the dynamic pressure, so as to realize synchronous acquisition of 12-point fluctuation point signals under different static pressures.
It should be further noted that, as shown in fig. 3, the pressure sensor 141 in this embodiment detects actual static pressure and dynamic pressure, and compares the detected pressure signal with the standard pressure through the comparison module 142, and when the detected pressure signal is smaller than the standard pressure, the detected pressure signal is fed back to the micro motor 143 to rotate to tighten the bandage and apply pressure to the bandage; when the comparison module 142 compares the actual static pressure with the dynamic pressure greater than the standard pressure, it feeds back to the micro-motor 143 for further operation to relax the bandage. That is, the pressure sensor 141 in this embodiment can ensure that the static pressure applied to the skin by the wrist band 150 during the gradient compression process is kept stable, and the tightness of the bandage disposed on the wrist band 150 is maintained by the micro motor 143 to keep the actual static pressure and the dynamic pressure stable.

It should be noted that the multi-channel AD conversion and control circuit 122/123 includes an AD conversion circuit group 122 and an FPGA123, that is, the FPGA123 corresponds to a control circuit, and synchronously recognizes and controls the AD converted signals. That is to say, each analog signal converts the analog signal into a digital signal in an AD conversion manner, the analog signal is subjected to acquisition control and data buffering by the AD conversion circuit group 122 and the FPGA123 and is connected to the ethernet chip in a GMII interface manner, and the ethernet chip is used as a transmission bridge between the sensor array 110 and the evaluation unit 130, so that the two signals can be well matched, synchronous acquisition and storage of 12 point signals can be realized, the number of pins can be reduced, the chip area can be reduced, and the like, and a simpler, faster, more stable and safer ethernet access scheme is provided for the circuit chip.
It should be noted that the sensor array 110 transmits each pulse wave signal to the preamplifier circuit 121, the pressure sensor 141 transmits the pressure signal in the wrist strap 150 to the preamplifier circuit 121, and then the sensor array 110 signal and the wrist strap 150 pressure signal are amplified. The preamplifier circuit 121 includes a first-stage amplifier circuit and a second-stage amplifier circuit, the first-stage amplifier circuit includes a piezoelectric amplifier for amplifying signals of the pressure sensor 141, and a subtractor for amplifying the acquired pressure signals of the 12 fluctuation points and signals of the static sensor of the wristband 150, and the second-stage amplifier circuit is used for adjusting level signals.
Specifically, as shown in fig. 5, the output terminal of the power supply module 127 is connected to the input terminal of the isolation power supply 128, and the output terminal of the isolation power supply 128 is connected to the pre-amplifier circuit 121 and the multi-channel AD conversion and control circuit 122/123. The input end of the optoelectronic isolation driving circuit 125 is connected to the output end of the multi-channel AD conversion and control circuit 122/123, the output end of the optoelectronic isolation driving circuit 125 is connected to the input end of the voltage-applying circuit 126, the output end of the voltage-applying circuit 126 is connected to the voltage-applying unit 140, the input ends of the circuit isolation driving circuit and the ethernet chip 124 are connected to the output end of the multi-channel AD conversion and control circuit 122/123, and the output ends of the circuit isolation driving circuit and the ethernet chip 124 are connected to the input end of the evaluation unit 130. As can be seen from the above connection relationship, the pre-amplifier circuit 121 and the multi-channel AD conversion and control circuit 122/123 are both powered by the isolated power supply 128.
Specifically, as shown in fig. 6, the evaluation unit 130 includes an input module 131, a control module 132, a display module 133, and a storage module 134. The input module 131 is configured to receive a signal acquisition request, where the signal acquisition request is configured with user basic information. The control module 132 is configured to control the sensor array 110 to acquire actual static pressure and dynamic pressure at each fluctuation point of different static pressures of the human body according to the signal acquisition request; and the control module is also used for converting the processed pressure signals into characteristic parameters, matching corresponding models according to the characteristic parameters and evaluating the functional state of the human body according to the models. The display module 133 is configured to display the human body state evaluation result, and the storage module 134 is configured to store the human body state evaluation result. That is, firstly, the input module 131 performs input acquisition of basic information of a user, then the control module 132 controls the sensor array 110 to perform synchronous acquisition of signals of human body fluctuation points according to the information acquisition signals, and then the signal processing unit 120 processes the signals of the fluctuation points, and the display module 133 and the storage module 134 in the evaluation unit 130 display and store the evaluation results of the processed actual static pressure and dynamic pressure of the fluctuation points.
As shown in fig. 6, the user basic information input by the input module 131 includes basic information such as the name, sex, and collection time of the person to be collected, wherein the year, month, and day of the collection time are automatically generated. After the acquisition is started, the acquisition equipment sends data to the port to perform synchronous acquisition on 12 fluctuation point signals. When the automatic pressurization mode is adopted for collection, if the collected object feels that the pressure is too large and the body feels uncomfortable, the operator can stand immediately to stop and store the data, and the data is automatically stored.
It should be further noted that, after the evaluation unit 130 collects the result of the human body state, the pulse wave waveform and the static pressure value of each composite sensor are displayed and stored in real time, and at this point, the signal collection process is finished. The evaluation unit 130 may calculate a corresponding pulse wave conduction velocity according to the synchronously acquired human body data, construct morphological characteristics of a pulse wave by using an orthogonal polynomial, calculate the number of beats of a respiratory pulse wave according to a pulse rate and a respiratory rate, and evaluate a functional state of a human body according to a pattern recognition algorithm such as a neural network.
Optionally, after the functional status of the human body is evaluated, the wristband 150 is unfastened to observe whether the data of the collected person meets the requirements.
