Description

Technical Field

[0001] The present application relates to the technical field of neurobehavioral ability devices, and in particular to a neurobehavioral ability testing device. Background Art

[0002] Neurobehavioral ability is one of the key indicators for assessing the work performance of occupational groups. Whether employed in civilian or military positions, the neurobehavioral ability of workers determines the efficiency and effectiveness of task completion. Different occupations have specific requirements for workers' neurobehavioral abilities. Testing, evaluating, and screening human neurobehavioral abilities are crucial for improving the work efficiency of workers in specific positions. Existing neurobehavioral ability testing technologies have been continuously updated with the rapid development of computer technology (such as the NES-C3 computerized neurobehavioral evaluation system, currently the most widely used in this field). The test items designed are becoming increasingly diverse, the test indicators are becoming increasingly refined, the operation procedures are becoming increasingly complex, the calculations are becoming increasingly complex, and the testing time is increasing. This technology has made significant progress in the intelligent, personalized, information-based, and refined testing of human neurobehavioral abilities and has been widely used.

[0003] However, after more than a decade of conducting extensive research on neurobehavioral assessments using this technology, we have discovered the following significant deficiencies:

[0004] (1) It is not suitable for batch screening of neurobehavioral abilities of large sample groups. In actual application at the grassroots level, the problem is not how to conduct comprehensive, accurate, systematic, and in-depth testing and evaluation of a small number of target individuals, but how to quickly conduct preliminary screening of neurobehavioral abilities of large groups of people. Therefore, testing schemes with more sophisticated operations, more complex processes, and longer time consumption are not suitable for the above-mentioned groups.

[0005] (2) The basic ability requirements for the subjects are too high. Existing technologies have high requirements for the subjects' education level, computer operation proficiency, comprehension ability, and sobriety. Otherwise, it is very easy for experimental bias to occur, resulting in errors or even mistakes in the test results. For example, in the applicant's previous research, it has been found many times that many subjects in grassroots units are not proficient in computer operation, have low education level, and have limited comprehension ability, which leads to erroneous test results or even inability to complete the test.

[0006] (3) The calculation of test results is complex. The prior art uses the NAI value (neurobehavioral ability index) to reflect the final neurobehavioral ability of the test subjects in different test items. This NAI value is comprehensively calculated by a computer based on multiple process parameters such as the average test time, the number of correct tests, the number of incorrect tests, the average dispersion of the number of correct tests, and the average dispersion of the test time of the test subjects and the standard reference population. The calculation process is very complex and cumbersome.

[0007] (4) The on-site test operation and organization are time-consuming and laborious. Before implementing the above technology in the population, it is necessary to conduct a pre-test on each test subject to familiarize the test subject with the test method and avoid test bias caused by unskilled operation during the formal test. At the same time, due to the variety of test items developed by this technology, the time required for each test subject to complete a test during the on-site formal test is 25-30 minutes, and the test results cannot be immediately displayed (requiring background processing and calculation), resulting in a very high difficulty in on-site organization and implementation, and the compliance of the test subjects is not high.

[0008] In summary, in view of the above deficiencies of the prior art, developing a simple device for large-scale and rapid measurement of neurobehavioral ability has important value and urgent need for the preliminary screening of the neurobehavioral ability of occupational post operators in grass-roots units.

[0040] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0041] "Neurobehavioral ability" generally refers to the ability of an individual's nervous system to regulate and control their own behavior. Neurobehavioral ability tests are a series of methods and tools used to evaluate an individual's nervous system function and behavioral performance. Neuroreflex tests are one type of neurobehavioral ability test, mainly detecting the speed and accuracy of neuroreflexes.

[0042] Existing neurobehavioral ability test devices have problems such as being unsuitable for batch screening of the neurobehavioral abilities of a large sample size population, having too high basic ability requirements for the test subjects, complex calculation of test results, and time-consuming and laborious on-site test operation and organization.

[0043] The neurobehavioral ability test device provided by this application has the advantages of simple structure, low cost, simple operation, easy to master, intuitive results, and efficient evaluation.

[0044] The following will detail the specific structure of the neurobehavioral ability test device provided by this application in conjunction with the accompanying drawings.

[0045] Refer to Figures 1-6 As shown, the embodiments of this application provide a neurobehavioral ability test device, including a dropping rod 1 and a release member 2 provided on the dropping rod 1;

[0046] The dropping rod 1 can be a cylindrical rod, can be made of rubber, or can be a wooden stick with a smooth outer surface. The release member 2 can be a hand-held member, such as a handle, a cord, a grip, etc. The dropping rod 1 is provided with a ring-grip area and a scale area from bottom to top. There is a scale mark 11 on the scale area of the dropping rod 1; the extending direction of the scale mark 11 is the same as the extending direction of the dropping rod 1. The minimum scale of the scale mark 11 is the zero scale, and the zero scale is located at the bottom end of the scale area. The maximum scale of the scale mark 11 is located at the top end of the scale area;

[0047] The release area is used for the tester to release the device and start the test; the ring-grip area can be a 10 - 15 cm non-scale area for the starting positioning of the habitual hand of the test subject before the test; the scale area can be a 40 - 60 cm area marked with scale lines and readings for the test subject to read and display the test results. The accuracy of the scale mark 11 can be in centimeters, and its length matches the scale area or is less than the scale area. The scale mark 11 can be 0 - 40 cm.

[0048] A neurobehavioral ability test device provided by an embodiment of the present application. Before the test, the tester holds the release member 2 in the release area, and the subject holds the ring grip area with their habitual hand in a ring grip without contacting the device; when the test starts, while the tester sends a start signal, the release member 2 is released to release the test device; after receiving the start signal, the subject tries to hold the tester as quickly as possible; the horizontal scale reading corresponding to the upper edge of the habitual hand of the subject holding the test device is read as the test result. The test result is the height of the device's fall. Since the height of the device's fall is proportional to the square of the reaction time, this reading can accurately reflect the subject's reaction time, thereby reflecting their neurobehavioral ability.

[0049] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the dropping rod 1 includes a housing 12. The housing 12 can be a cylindrical housing. A groove 13 is provided on the scale area of the housing 12. The groove 13 is a rectangular groove with a certain length. A connecting plate 14 is provided on the groove 13. The connecting plate 14 can be a rectangular plate body and is matched with the groove 13. The scale mark 11 is set on the outer surface of the connecting plate 14.

[0050] Referring to Figures 3-5 As shown, in some embodiments, in order to be applicable to different populations, a diameter adjustment component 15 is provided on the dropping rod 1. The diameter adjustment component 15 is used to sleeve the diameter of the dropping rod 1, so as to facilitate testing and grasping by people with different palm sizes. The diameter adjustment component 15 includes an airbag 151 and an air valve 152;

[0051] The airbag 151 is tubular, can be made of rubber, has good elasticity and wear resistance. The airbag 151 sleeves the scale area of the housing 12. Both the upper and lower ends of the airbag 151 are connected to the outer wall of the housing 12 to achieve sealing;

[0052] In order to facilitate viewing the scale mark, an avoidance groove is provided on the airbag 151. The avoidance groove is matched with the connecting plate 14. The edge part of the avoidance groove is connected to the edge part of the connecting plate 14, so as to ensure the sealing while exposing the scale mark;

[0053] The housing 12 has an inner cavity 16. The air valve 152 is provided on the housing 12 and is connected to the inner cavity 16 of the housing 12. The air valve 152 can be provided at the upper end of the housing 12. An air hole 17 connecting the inner cavity 16 and the airbag 151 is provided on the housing 12. By inserting an air needle into the air valve 152, the airbag 151 can be inflated or deflated, so as to adjust the outer diameter of the dropping rod 1, and further facilitate testing and grasping by people with different palm sizes.

[0054] In some embodiments, the diameter adjustment component 15 further includes a connecting rod 153 and an elastic tendon 154;

[0055] The connecting rod 153 is a conventional rod body. The connecting rod 153 is disposed in the inner cavity 16 of the housing 12. The connecting rod 153 is coaxial with the housing 12, and the length of the connecting rod 153 matches the length of the airbag 151.

[0056] A plurality of air holes 17 are evenly provided on the housing 12. The plurality of air holes 17 are evenly distributed around the circumferential surface of the housing 12, and multiple circles of air holes 17 are evenly distributed along the axial direction of the housing 12. The elastic ribs 154 are elastic rib strips. The plurality of elastic ribs 154 correspond to the plurality of air holes 17 one by one. The inner ends of the plurality of elastic ribs 154 are fixedly provided on the outer wall of the connecting rod 153, and the outer ends of the plurality of elastic ribs 154 all penetrate through the corresponding air holes 17 and are connected to the inner wall of the airbag 151. The elastic ribs 154 are in clearance fit with the air holes 17 to avoid affecting inflation and deflation.

[0057] As Figure 4 shown, it is a schematic diagram of the state where the airbag 151 is not inflated. At this time, the airbag 151 fits against the outer wall of the housing 12 under its own elastic force, and the elastic ribs 154 are in a straightened state; as Figure 5 shown, it is a schematic diagram of the state where the airbag 151 is inflated. The airbag 151 inflates and expands to wrap the housing 12, and the plurality of elastic ribs 154 are all in a stretched state. The plurality of elastic ribs 154 apply an inward pulling force to the airbag 151, causing the airbag 151 to expand evenly, making the airbag 151 as a whole cylindrical and facilitating the tester to grip.

[0058] In some embodiments, the outer wall of the airbag 151 is provided with anti-slip patterns. The anti-slip patterns are annularly arranged around the circumferential surface of the airbag 151, and multiple anti-slip patterns are evenly distributed along the length direction of the airbag 151.

[0059] Referring to Figure 6 shown, in some embodiments, in order to prevent the dropping rod 1 from falling and being damaged when not caught, a buffer component 18 is provided at the bottom end of the dropping rod 1. The buffer component 18 reduces the impact force. The buffer component 18 includes a head 181, a telescopic member 182, and a spring 183.

[0060] A connecting cavity 19 is provided at the bottom end of the housing 12. The connecting cavity 19 can be a circular cavity. The inner wall of the lower part of the connecting cavity 19 is provided with an internal thread. The upper outer wall of the head 181 is screwed to the inner wall of the bottom end of the housing 12. A through hole is provided in the middle of the head 181, and the through hole can be a round hole.

[0061] The telescopic member 182 is disposed in the head 181. The telescopic member 182 can be a T-shaped member. The telescopic member 182 includes a clamping portion and a connecting portion. The clamping portion can be a circular chuck, and the connecting portion can be a connecting rod. The connecting portion is fixedly provided at the bottom end of the clamping portion, and the two can be an integral structure. The clamping portion is clamped to the inner wall of the top end of the head 181, and the bottom end of the connecting portion penetrates through the through hole of the head 181.

[0062] The spring 183 is disposed within the connection cavity 19 of the housing 12. Both ends of the spring 183 respectively abut against the top end of the connection cavity 19 and the top end of the telescopic member 182;

[0063] The spring 183 is always in a compressed state. The bottom end of the telescopic member 182 extends out of the end head 181. When the dropping rod 1 drops and contacts the ground, the bottom end of the telescopic member 182 first contacts the ground, causing the spring 183 to be further compressed, achieving a buffering effect, thereby reducing the impact force and preventing the dropping rod 1 from being damaged.

[0064] In some embodiments, the buffer assembly 18 further includes a rubber head 184, and the rubber head 184 is a spherical head made of rubber;

[0065] The rubber head 184 is fixedly provided at the bottom end of the telescopic member 182. The bottom end of the rubber head 184 is spherical, and the bottom end of the rubber head 184 is snap-fitted with the bottom end of the end head 181.

[0066] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the release member 2 is a cord. The cord is fixedly provided at the top end of the dropping rod 1. Before the test, the tester holds the cord in the release area by hand. During the test, the tester releases the cord, causing the dropping rod 1 to fall freely, and the testee grasps the dropping rod 1.

[0067] As recorded by the above technical features, the working principle of the neurobehavioral ability test device provided by the present application in the actual application scenario is as follows:

[0068] The usage method is as follows: The tester holds the thin cord at the upper end of the measurement test device demonstration area and remains stationary. The testee's habitual hand makes a virtual grip (not in contact with the device) around the lower ring grip area of the test device. The upper edge of the habitual hand is flush with the "habit scale line" of the scale area, and the test preparation is completed. During the test, the tester emits a signal (the signal can be a visual or auditory signal), and at the same time releases the measurement device. At the same time, the testee grasps the measurement device as quickly as possible to prevent it from falling. The reading (S) of the horizontal scale line corresponding to the upper edge of the habitual hand when the testee holds the measurement device is the falling height (H) of the measurement device. According to the free fall motion formula H = 1 / 2gT 2 It can be deduced that T = (2H / g) 1 / 2 , and since H = S, it can be obtained that T = (2S / g) 1 / 2 , where g is the acceleration due to gravity and T is the reaction time. From this, we can know that the falling height S of the test device is proportional to the square of the reaction time T. Therefore, this reading can accurately reflect the reaction time of the testee, thereby reflecting his neurobehavioral ability.

[0069] For example, 8 male trainees aged 21 - 22 were selected to conduct a study on the influencing factors (reaction time) of neurobehavioral ability in a room at 26°C. The influencing factor was satiety. The reason for choosing this factor is that after eating, the parasympathetic nerve of a person becomes excited, the peristalsis of the digestive tract increases, blood supply increases, while the blood supply to the brain relatively decreases, making people more prone to drowsiness and a decline in reaction ability. The measurement method is as follows. Three hours after breakfast, the neurobehavioral ability of the trainees before meals was tested. When measuring the visual reaction time, the tester released the measuring device. After the tested person saw the measuring instrument fall, they were required to hold the measuring instrument as quickly as possible to stop its fall. The reading of the scale line held by them could reflect the reaction time of the tested person. The visual reaction time and auditory reaction time of each tested person were measured 5 times, and the average of the reaction times was taken. Forty minutes after lunch, the neurobehavioral ability of the trainees after meals was tested, and the testing method was the same as above. The measured data is as follows:

[0070] Test results (cm) of the visual simple reaction time neurobehavioral ability of 8 trainees before and after lunch:

[0071]

[0072] Paired t - test was performed on the measured data.

[0073] α = 0.05;

[0074] H0: μ1 - μ2 = μ = 0, the neurobehavioral ability before and after meals is the same;

[0075] H1: μ1 - μ2 = μ ≠ 0, the neurobehavioral ability before and after meals is different;

[0076]

[0077] v = n - 1;

[0078] n = 8, Σd = 63.6, d = 12.72, S d = 9.01, t = 3.99;

[0079] t > t 0.01 / 2,7 , P < 0.01, reject H0 at the α = 0.05 level, accept H1, and the difference is statistically significant.

[0080] Among them, α is common sense, the significance level of the test, which means the probability of wrongly rejecting H0 or the risk of accepting H1, and it is a pre - specified probability value that determines the standard of small - probability events;

[0081] H0 and H1 are a set of opposing hypotheses;

[0082] μ1 is the overall data of the neurobehavioral ability test results of the trainees before meals, μ2 is the overall data of the neurobehavioral ability test results of the trainees after meals, and μ is the difference between μ1 and μ2, that is, the difference in the neurobehavioral ability test results of the trainees before and after meals;

[0083] d is the difference in the neurobehavioral ability test results of the trainees before and after meals; Σd is the sum of d; is the mean of d; is the standard deviation of ; S d is the standard deviation of d; n is the sample size; v is the degrees of freedom;

[0084] t is a sample statistic used to measure whether there is a difference in the self-control of the sample before and after; t 0.01 / 2,7 is a standard value. As long as t > t 0.01 / 2,7 it can be deduced that P is less than 0.01;

[0085] P is the probability of wrongly rejecting H0. As long as P is less than α, it can be concluded that the hypothesis test rejects H0 at a certain level and accepts H1, indicating that the difference in the test result data is statistically significant.

[0086] To further prove that the neurobehavioral ability of the trainees after meals is significantly lower than that before meals. Similarly, we conduct a test on the neurobehavioral ability of a group of simple trainees before and after lunch in terms of simple reaction time: The test method is changed to that the tester emits a sound signal (such as "ah") while releasing the device. The tested person is always in a closed-eye state and tries to hold the measuring instrument as quickly as possible after hearing the signal to stop its falling. The reading of the scale line held can reflect the reaction time of the tested person; other contents are the same as above. The data is as follows:

[0087] Test results (cm) of the neurobehavioral ability of 8 trainees before and after lunch in terms of simple reaction time:

[0088]

[0089] Similarly, paired t-tests are performed on the measured data;

[0090] α = 0.05;

[0091] H0: μ1 - μ2 = μ = 0, the neurobehavioral abilities before and after meals are the same;

[0092] H1: μ1 - μ2 = μ ≠ 0, the neurobehavioral abilities before and after meals are different;

[0093]

[0094] ν = n - 1;

[0095] n = 8, Σd = 62.8, d = 12.72, Sd = 2.09, t = 10.6;

[0096] t > t 0.01 / 2,7 , P < 0.01. At the α = 0.05 level, H0 is rejected and H1 is accepted, and the difference is statistically significant.

[0097] Based on the above statistical results, it can be inferred that the neurobehavioral ability of the trainees after meals is significantly lower than before meals, that is, having a meal can lead to a decline in a person's neurobehavioral ability. This implementation case indicates that this design scheme can be used for the rapid evaluation and screening of a person's neurobehavioral ability.

[0098] The neurobehavioral ability testing device provided by this application has the following significant advantages compared with the existing rotating shaft:

[0099] 1. Simple structure and low cost. This design scheme can be made only with simple equipment such as bamboo poles and wooden sticks, can be mass-produced in a short time, and the cost is extremely low and can be ignored.

[0100] 2. Simple operation and easy to master. This design scheme does not require electric drive or computer control; the test operation is simple, and no professional personnel are required to conduct complex training on the subjects before the test. It is not affected by the subjects' comprehension ability and educational level, has a low implementation difficulty, and is easy to understand and master.

[0101] 3. Intuitive results and efficient evaluation. This design scheme directly uses the scale in the test area as the final test result, without the need for complex formula calculations, and can directly reflect the neurobehavioral ability of the tester; it only takes a few seconds to complete a test trial to display the test result in a timely manner, and the evaluation efficiency is much higher than the existing neurobehavioral evaluation technologies.

[0102] 4. Wide practicability and high promotion degree. This design scheme is widely applicable to the neurobehavioral ability evaluation of general occupational groups and military operation groups, can conduct batch large-scale tests on the target population in a short time, quickly screen out excellent objects with neurobehavioral ability suitable for specific positions, has high practicability, and is suitable for popularization and application in various occupational positions.

[0103] Based on the above statistical results, it can be inferred that the neurobehavioral ability of the trainees after meals is significantly lower than before meals, that is, having a meal can lead to a decline in a person's neurobehavioral ability. This implementation case indicates that this design scheme can be used for the rapid evaluation and screening of a person's neurobehavioral ability.
