Description

The utility model (hereinafter PM) relates to the field of occupational medicine and can be used for pre-shift and (or) periodic, during the working day, psychophysiological rapid control of the functional state of personnel working at hazardous production facilities, as well as for individual self-control by employees of their own conditions in working and resting conditions. The functional state of the body is a combination of characteristics of physiological functions and mental qualities that ensures the effectiveness of a person performing the required work operations (see: Zagryadsky V.P., Sulimo-Samuillo Z. Physical exercises of a modern person. - L.: “Science. Leningrad Dep. ”, 1982 - 96 p.).

The relevance of pre-shift and (or) periodic psychophysiological control of persons working at hazardous production facilities is due to the high importance of the human factor in emergency situations. This problem is of particular importance for objects with harmful and dangerous factors of the working environment (toxic components of the air, monotony, tension of operator activity, etc.), which can accelerate the body's fatigue and provoke functional state disorders that increase the likelihood of decreased attention, the occurrence of psychoemotional stress, erroneous actions and inappropriate reactions.

Currently, various hardware-software complexes (AIC) are known and used in practice for pre-shift inspection of personnel employed at hazardous production facilities, for example: ESMO system (registration of pressure, pulse, arrhythmia, body temperature, alcohol test, drug test) // Internet resource. - (appeal date 04/01/2016); Agro-industrial complex of psychophysiological control “KAP 8-01-operator” (indicators: heart rate variability, simple / complex visual-motor reactions, combined techniques) // Internet resource. - (date of treatment 04.01.2016). Also known complexes are "EKOZ-01" (Internet resource. -.), "Psychophysiologist-N" (Internet resource. - (accessed 01.01.2016) and "Forecast" (patent No. 2289297), providing indicators of blood pressure, heart rate contractions, heart rate variability, coordination, simple and complex visual-motor reactions, etc. There is also a device for determining the psychophysiological state of a person (patent for invention No. 2214166), implemented in industrial design No. 64701 in the form of a computer mouse.

A common drawback of these analogues is the time factor for the inspection of personnel. In the best case, the real time spent per person is at least 5 minutes. For production teams, even with a minimum number of personnel, for example, 20 people, the total inspection time at one agro-industrial complex will be an hour and a half, which is unacceptable for pre-shift control at the checkpoint of the enterprise. An increase in the number of parallel-working at the entrance APC for greater throughput inevitably requires an increase in the staff of the medical staff that controls the operation of the agro-industrial complex and the actions of subjects when performing tests that perform the application of sensors, cardio electrodes, etc.

The closest to the claimed PM technical solution can be a device for the Schulte-Platonov test, for example, which is part of the NS-Psychotest computer complex (Internet resource. - (access date 01/05/2016) and contains a block for presenting visual test images to the test employee) , a unit for generating test images, a measuring instrument for the reaction time of the test subject and a unit for evaluating indicators. As test images in this device, sets of numbers in the form of specially constructed tables are used. about allows you to evaluate the rate of perception of information and the speed of the orientational reaction.

The disadvantage of this known technical solution as well as the above analogues is the duration of the test, which is unacceptable for performing an express assessment (screening) of the functional state of workers under pre-shift control. In addition, the prototype device does not allow to evaluate the functions of memory and motor-motor response in a single testing algorithm with an assessment of the rate of perception of information and the speed of the approximate reaction. A frequent drawback of most analogs and prototypes, including the need for a test subject to use the computer mouse or a special button panel, which reduces the speed of the test, especially for people who do not use a computer.

The basis of this PM is the solution of the problem of psychophysiological rapid assessment (screening of no more than 1 min) of the functional state of personnel working at hazardous production facilities through the formation of a system of test tasks (images) allowing to obtain an assessment of cognitive functions in a single algorithm: memory, attention, indicative and hand-eye reactions.

The technical result is achieved by the fact that in the device for psychophysiological rapid control of the functional state of personnel working at hazardous production facilities, which contains a unit for presenting visual test images to the test employee, a test image forming unit, a test subject's reaction time meter, visual test images for presenting the test subject, the form of a touch panel display, the input of which is connected to the output of the block forming a set of test images containing the programmer of test images and the memory element of the set of algorithms for presenting test images, and ensuring their location on the touch panel of the display in a random order that changes after each action of the test person, in addition, the output of the unit for presenting the test image to the test person is connected to the input of the subject's reaction time meter at each of its actions , the output of which is in turn connected to the input of the indicator evaluation unit containing the memory element of individual reaction time norms for the entire test person la and analyzer provides comparison of the performance of the reaction time of each test area with its individual rules to issue commands to the resultant signal light.

The applicant has not identified technical solutions that are identical to the declared PM, which allows us to conclude that it meets the criterion of "novelty."

The essence of the PM is illustrated in the drawing.

In FIG. 1 shows a block diagram of the claimed technical solution.

In the drawing (Fig. 1) the following are indicated: 1 - unit for presenting visual test images to the test employee, 2 - test image formation unit, 3 - test image programmer, 4 - memory element of the set of test image presentation algorithms, 5 - test reaction meter, 6 - unit for evaluating indicators, 7 - memory element of individual norms, 8 - analyzer, 9 - signal indicator.

The device operates as follows.

Prior to the psychophysiological rapid control of the functional state of personnel employed in production using the inventive device in a constant mode, workers undergo a preliminary test examination in advance to determine individual corridors of the norm of indicators during a working day, week or month, depending on the specifics of the production process. These individual norms enter the device memory, forming a database. As surveys accumulate, the database expands and individual standards are refined.

During the psychophysiological express control of the functional state of the personnel, the operator conducting it previously using the touch panel of the visual test image presentation unit 1, block 2 and programmer 3 sets the type of test images and selects the algorithm of the subject's actions from the available set in the memory element 4. Thus, before the start of testing, the PM operator installed the necessary set of programs. Each subject begins testing by pressing the "Start" button and then dialing on the touch panel of unit 1 his identification number. After that, from the output of block 2 for forming test images (numbers, letters, simple arithmetic operations, images of most objects or animals known to others), the generated set of control test images is displayed on the touch panel of block 1. Their location on the touch panel is formed by block 2 in a random order and changed after each action of the test person. The test subject performs actions in accordance with a given algorithm. The time meter of the reactions of test 5 with each of its actions records the time spent. The signals from the test reaction time meter 5 are fed to the input of the indicator evaluation unit 6, in which the response time indicators are individually extracted from the memory element 7 using the identification number of the reaction time indicators with the individual zone of the test norm. Then, in the analyzer 8, the obtained reaction time indicators of the given subject are compared with his individual norm zone to issue the resulting command to the signal indicator 9. An example of the implementation of the utility model.

To implement the utility model as a block for presenting visual test images to a test subject made in the form of a touch panel of display 1, for example, a Samsung Galaxy Tab 7.0 tablet model SM-T 210 can be used. Block 2 of forming a set of test images and the order of their location on the touch panel can be made on the basis of the central processor of a tablet PC Samsung Galaxy Tab 7.0 model PX1986 using a video accelerator model Vivante GC1000. The test image programmer 3 included in this block and the memory element of the set of algorithms for presenting test images 4 can be represented as part of the MicroSDHC 4 Gb Class 4 Transcend memory block. Subject 5’s reaction time meter is based on the RAM of the Samsung Galaxy Tab 7.0 tablet SM-T 210. To form a score unit 6, including memory 7 and image analyzer 8, the central processor of the Samsung Galaxy Tab 7.0 tablet can also be used model PXI986, while the memory unit 7 is made in the form of a microSDHC 4 Gb Class 4 Transcend memory card. The signal indicator 9 can be performed, for example, according to the type of LED traffic light - “green” - norm, “yellow” - limit of the normal range (a second test or doctor’s control is possible), “red” - mandatory doctor’s control.

PM testing was performed on 7 volunteer operators. The first step of the test was to present the subject on the display panel with an image in the form of a conditional identification number of four single and double digits for a fixed period of 2 s. The subject was tasked with memorizing the digits of the identification number and reproducing them sequentially on the touch panel of the display. In this case, as a test image, a set of 10 digits was used, distributed on the touch panel of the display in a random and variable order after each action. The time spent by the subjects ranged from 9 s to 17 s; two subjects made one mistake in the set of test numbers.

This preliminary testing aimed at convincing the legitimacy of applying PM in the simplest version of the possible algorithms for its application. Indeed, in the PM there is a task that includes monitoring the RAM - remembering the identification number, approximate reaction, attention function and the speed of the hand-eye reaction - finding the right numbers on the field of the touch panel. The whole test took less than 20 seconds and nevertheless gave a generalized screening assessment of the psychophysiological functional capabilities of the examined contingent of subjects.

Thus, the above results confirm the possibility of achieving its purpose with the help of the claimed PM, namely, solving the psychophysiological rapid assessment task (screening lasting no more than 1 min) of the functional state of personnel working at hazardous production facilities in conditions of work and leisure.

Given the entry of computer technology into all areas of modern life and the prevalence of tablet PC options, the claimed PM can be widely used in occupational medicine. This ensures that the claimed PM meets the condition of patentability "industrial applicability".

The effectiveness of the claimed PM lies in the fact that, with ease of implementation, it provides, with minimal time, rapid control or screening assessment of the functional state of personnel working at hazardous production facilities.
