Description

Method and automated device for applying, intervening and recording human psychological stress

Technical Field

The invention relates to the technical field of psychological stress instruments, in particular to a method and an automatic device for applying, intervening and recording human psychological stress.

Background

The mirror image (mirror image) experiment is a commonly used psychological experiment, initiated by the scotch (d.starch) in 1910. In the mirror drawing experiment, a person to be tested looks at a graph through a mirror, and draws the graph through a pen. Because the patterns seen by the testee in the mirror are inverted from top to bottom and are unchanged from left to right compared with the original patterns by the reflection of the mirror, the testee often has a drawing method with opposite vertical strokes during drawing, which brings certain difficulty and psychological stress to the testee who performs the mirror drawing experiment.

A mirror image (mirror image) instrument is a psychology usual instrument that analyzes a process of forming a motor skill. The existing instrument can record the time and failure times required for drawing the whole graph. In the microscopic examination, the time and the error number of the pattern of the human subject are generally used for representing the operation proficiency of the human subject, and the change of the migration ability of the human subject is represented by comparing experimental data.

At the same time, the microscopic examination is a standard stimulation procedure that can be used clinically to apply psychological stress to a subject. A great deal of evidence indicates that more than 1/3 of patients with coronary heart disease can develop myocardial ischemia in a state of psychological stress, which is called psychological stress myocardial ischemia (MSIMI). The national institute of physicians and related doctors, the national institute of general conference double heart (heart mental) study group, according to the current research progress, meta-analysis and foreign related guidelines, formulated "diagnosis and treatment expert consensus of myocardial ischemia for patients with coronary heart disease caused by psychological stress" (J. Of cardiovascular diseases, 2016, 44 (1): 12-18). The consensus indicates that: MSIMI, also known as mental stress induced myocardial ischemia, refers to myocardial ischemia induced by a patient under psychological stress, unlike myocardial ischemia induced by exercise and drug loading. Such psychological stress may be simulated by standard stimulation procedures for diagnosis, in addition to psychological, social, etc. factors. Psychological stress can be applied clinically using standard stimulation procedures to induce MSIMI, including mental arithmetic, public speech accompanied by anger recall, microscopic and disturbing color card testing, and the like.

As described above, the microscopic examination is a standard stimulation procedure that can be used clinically to apply psychological stress to a subject. But how effectively the magnitude of the difficulty and the degree of psychological stress experienced by the subject during the course of the experiment should be recorded and analyzed is an unresolved problem.

Clinically, standard stimulation procedures for applying psychological stress are typically accomplished using a microscopic instrument and manually assisted methods: when the patient operates the microscopic scanner, the patient is stimulated by making a sound manually, the response of the patient after the error is recorded by observation, the duration time, the frequency and the like of the error are recorded, and various indexes of the patient under stress states such as blood pressure, heart rate, respiration and the like are measured. At present, the accuracy and timeliness of data cannot be guaranteed by manual recording, and a great deal of time and energy are consumed by medical staff in a manual assistance mode. Currently, there is no automated means for applying, intervening, measuring and analyzing psychological stress states of a subject by means of a microscopic examination. At the same time, the display is used to display the data and curves of the measurement results, and the means for processing the algorithm and generating the response data index by the computer is not yet available.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Because of the difficulty and psychological stress faced by the subject in the microscopic experiments, the system can be expressed by quantifiable data such as the number and frequency of errors of the subject, the time duration of the errors, the error correction speed and the like in the microscopic process in a period of time. Therefore, the device of the invention records and analyzes the psychological stress state of the tested person by automatically measuring, recording and calculating the above quantitative data and calculating the related index through an algorithm.

In addition, on the basis that the mirror drawing experiment brings difficulty to the testee, besides the alarm sound of mirror drawing mistakes, the device increases various prompting sounds to prompt the testee to accelerate the mirror drawing speed and increase the tension of the testee. In this way, a stronger psychological stress and psychological stress is applied to the subject.

When the device is operated, various indexes such as blood pressure, heart rate, respiratory frequency, electrocardiogram, electroencephalogram, facial expression change and the like of a tested person can be selectively measured; converting the information into data and recording; the various data are calculated through an algorithm to obtain various numerical values and curves, and indexes such as the strength, the duration, the adjustment capacity and the like of psychological stress of the tested person during the microscopic drawing are represented and recorded in a quantified mode.

The device can record the time point and the error duration of psychological stress errors of a tester in a certain time period, represent the test result in a curve form, and calculate and represent related indexes.

As shown in fig. 1, an automated apparatus of the present invention for applying, intervening and recording human psychological stress comprises:

and the calculating and displaying module is used for calculating each item of data to obtain the total stress rate, the stress rate per minute and/or the stress adjustment capability curve of the tested person in the test duration so as to quantitatively represent and record the strength, the duration and the adjustment capability index of the psychological stress of the tested person in the microscopic examination period.

The mirror comprises a main control board 1, a mirror 2, a base 3, a test board 4 and a side board 5;

The test board 4 is installed on the main control board 1, and main control board 1 is installed on base 3, and base 3 is connected with the one end of curb plate 5 through folding hinge 6, and curb plate 5 has draw-in groove 7, mirror 2 through the buckle 8 embedding of both sides in order to fix on curb plate 5.

Further, the applying and intervening module further comprises a top plate 9 and a shielding plate 10, wherein one end of the top plate 9 is connected with the other end of the side plate 5 through a support hinge 11, and the shielding plate 10 is connected with the other end of the top plate 9 through a folding hinge 12.

The mirror 2 in the present invention is a flat mirror for forming an image of a test pattern.

Preferably, the application and intervention module may further comprise a stiffening plate mounted behind the mirror 2 for further stiffening the mirror against too thin, shattering of the mirror.

The upper surface of the test board 4 has a test pattern 13 for the tester to trace. The conductive insulation of the test board and the test pattern in the present application are opposite. I.e. the test pattern is an insulating pattern when the test board is a conductive board and the test pattern is a conductive pattern when the test board is an insulating board.

The main control board 1 is also provided with a touch pen jack 14 for connecting the touch pen with the main control board in a wired manner.

The main control board of the invention comprises: the system comprises a singlechip module, a voice module, a low-level buzzer, a Bluetooth and wifi module and a power module, wherein the voice module, the low-level buzzer, the Bluetooth and wifi module and the power module are respectively connected with the singlechip module.

As shown in fig. 2, the automation device for applying, intervening and recording the psychological stress of the human being can be matched with a touch display screen (for example, a mobile phone or a PAD), a touch pen (which can be in the form of a conductive pen), a cloud storage server (not shown), APP software and the like for use.

The method for measuring and recording psychological stress and psychological stress state comprises the following steps:

The testee observes the graph to be drawn through the mirror surface (as shown in figure 3, the drawing graph (black strip line) of an irregular hexagonal insulating strip with the line width of about 5mm on the test board (the diagonal shading is the test board)), and draws the insulating strip graph by using the conductive pen as quickly and accurately as possible in a clockwise or anticlockwise manner, and the testee can feel inadaptation in the drawing process due to the fact that the mirror surface image is opposite to the actual image, the conductive pen always deviates from the graph, alarm sound can be generated once the conductive pen falls outside the insulating strip of the graph (the mirror drawing is wrong), and meanwhile, the testee can hear continuous electronic voice prompt to make his action faster, and psychological stress can be applied to the testee by the double stimulus, so that psychological stress is generated to the testee.

The invention describes and records the duration and time point of psychological stress caused by the microscopic errors applied to the testee by the experiment by recording the duration and time point of the microscopic errors.

The specific method comprises the following steps: the conductive pen falls on the test board outside the insulating strip pattern, which can lead to the connection of related circuits, further trigger an alarm in the circuit to give out alarm sound, and meanwhile, a control unit on the main control board of the system records the state of whether the related circuits are connected or not, namely the state of whether the tested person is in error or not at regular intervals (such as 1 second).

For example: we divide the total time tested by the testee, such as 5 minutes, into several time periods equally, which we call recording time period points, and the time of each recording time period point is fixed. Examples: if 1 second is taken as one recording period point, the total test time is 5 minutes, for example, and can be divided into 300 recording period points. The state (whether the state is communicated) of each recording time interval point is identified and stored through a singlechip and a memory on the main control board, the state is transmitted to a server (computer) specially processing and analyzing data through communication means such as Bluetooth, wifi and the like, and a matched software program is used at the server end to calculate a curve related to psychological stress through an algorithm.

The specific algorithm comprises the following steps:

total stress rate in test duration = effective stress duration/total duration tested

Note that: effective excitation duration = total length of mirror error, total length of test = total length of mirror error + total length of mirror correct.

Stress rate per minute = effective stress duration per minute/1 minute duration, wherein effective stress duration per minute = total duration of mirror errors per minute, 1 minute duration = total duration of mirror errors within 1 minute + total duration of mirror correctness.

The principle can also be extended by this:

The method for drawing the stress rate curve per minute in five minutes comprises the following steps: the stress rate per minute is calculated during the test, the time is taken as an X axis, the stress rate per minute is taken as a Y axis, and a change curve of the stress rate per minute is drawn.

Generating a stress regulation capacity curve of a tested person: calculating the average time length (average return time length) from each mirror drawing error to the first return correct mirror drawing position (the shorter the error return correct time length is=the stronger the adjustment capability) in each minute, and drawing a change curve of the average return time length in each minute by taking the time as an X axis and the average return time length in each minute as a Y axis.

The invention can be matched with other human body index detection equipment such as blood pressure, electrocardio, electroencephalogram and the like, and solves the problems of synchronous butt joint and parallel detection of multiple equipment.

The invention needs to be matched with other devices such as blood pressure, electrocardio, electroencephalogram and the like to finish synchronous detection and analysis of various indexes of human bodies in the early, middle and later stages of the test, and the specific method is as follows:

the invention can preset the rest time of the tested person before and after the test, and the tested person keeps the rest state in the rest time without carrying out the mirror drawing stress test (the rest time before and after the test and the test time length are the same, for example, five minutes). The device also provides synchronous detection equipment for blood pressure, electrocardio, electroencephalogram and the like, and is convenient for measuring various indexes of human body which is at rest before and after the test, and meanwhile, the software system reserves synchronous integration interfaces of various human body measurement data, so that synchronous calibration of each measurement equipment and an Internet clock can be realized, and various data comparison of human bodies on the same time axis can be realized.

The clock calibration method comprises the following steps: the invention designs a device start clock synchronization code, which adopts a time. Nist.gov (NIST Internet time service) synchronous clock. When the device is tested, the sent test start instruction is confirmed and recorded by the server, and the time of the server is corrected by NIST Internet time service. Similarly, the measuring equipment for blood pressure, electrocardio and electroencephalogram has the advantages that the time for beginning to measure is corrected through NIST Internet time service, and the clocks are consistent, so that the time synchronization of the testing process is ensured, and the change of various indexes of a tested person before and during the test can be accurately reflected.

The device of the invention improves the strength of psychological stress intervention by combining automatic voice with alarm promotion; in the process of the test of the testee, the testee can hear the prompting and reminding of the automatic voices with different tone, color and speech speed and the alarm (artificial voices or computer synthesized voices) to increase the urgency of the test of the testee, so as to improve the strength of psychological stress intervention. The method specifically comprises the following steps: after the tester does not make an error for more than 7 seconds, playing: "fast Point, then fast Point-! "(2 seconds long). Such as errors: when the touch pen is separated from the insulation route and touches the test board, the buzzer warning sound is continuously sounded. Wherein 'fast point, fast point again' can be adjusted to a plurality of natural human voices with different versions and languages, and the natural human voices are played in sequence, for example, the 'fast point o' is too slow-! "," fast, accelerate-! "quick again, quicken-! The time of the process is shorter, then quickly-! You are too slow-! "," o kuai, kuai-! "You are so slow-! "," Quickly Quickly-! "," Too slow, hurry up-! "

The device can be matched with other instruments to realize the comparison test of the same tester under the condition of psychological stress and non-psychological stress. (contrast measurement of blood pressure, heart rate, respiration, electrocardiography, electroencephalogram, etc.).

Considering that a plurality of users use the instrument continuously, each user uses at least 15-20 minutes, under the condition of no network, the device needs to store the detection record information of each user, and the detection record information is uploaded to a server when the network exists.

The invention can export and generate pictures or pdf files from related data, curves and other information, and store or send the pictures or pdf files to corresponding servers locally on the intelligent terminal.

The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
