[0012] In one embodiment, when the subject is in the step abnormal state, the pressure measured by the first pressure sensor is greater than 0, and / or the pressure measured by the second pressure sensor is less than a first preset pressure.
[0013] In one embodiment, the first preset pressure is a maximum value of the pressure measured by the second pressure sensor under a preset condition, and the preset condition is that the subject stands on the load area.
[0014] In one embodiment, the second sensor assembly has a detection portion configured to measure a number of leg lifting actions of the subject in a step test mode, and during the measurement of the number of leg lifting actions of the subject, the load area is located between the detection portion and the seating area along an arrangement direction of the detection portion and the seating area.
[0015] In one embodiment, the second sensor assembly comprises:
[0016] a support member, the assessment chair assembly having the support member arranged on opposite sides of the assessment chair assembly, and each of the support members being pivotally connected to the assessment chair assembly; and
[0017] a sensor body comprising a first sub-sensor and a second sub-sensor arranged oppositely, the first sub-sensor being connected to one of the support members, and the second sub-sensor being connected to the other support member, the sensor body triggering a counting signal when the subject is at least partially located between the first sub-sensor and the second sub-sensor.
[0018] In one embodiment, the support member comprises:
[0019] a first connecting rod pivotally connected to the assessment chair assembly; and
[0020] a second link pivotally coupled to the first link, an end of the second link coupled to the sensor body, the end of the second link distal to the sensor body movably disposed in the evaluation chair assembly.
[0021] In one embodiment, the evaluation chair assembly is formed with a guide, the second link on each side is provided with the guide, the guide is located at the bottom of the evaluation chair assembly, and the end of the second link distal to the sensor body is movably disposed in the guide.

The controller obtains the number of times the subject sits and stands during the sitting test and the time taken, thus enabling the subject to complete the sitting test. By monitoring the subject's sitting and standing state through the first sensor component, if an abnormal stepping state is detected, the stepping test mode is exited, and the second sensor component stops counting the number of leg lifts. This effectively prevents the subject from counting leg lifts while in an abnormal stepping state, resulting in a higher degree of objectivity in the stepping test results and reducing the likelihood of the subject performing the stepping test under abnormal conditions. Using the first sensor component for sitting test monitoring eliminates the need for additional monitoring devices, reducing costs and making the assessment chair assembly more compact. Using the first sensor component for sitting test reduces interference from human factors during the sitting test, resulting in more objective test results. Attached Figure Description

DETAILED DESCRIPTION
[0037] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation of the purpose of the present application, and should not be regarded as an improper limitation on the present application.
[0038] In the description of the embodiments of the present application, the terms "upper", "lower", "top", "bottom", orientation or position relationship are based on the orientation or position relationship shown in the drawings. Figure 2 In the embodiments of the present application, the up-down direction is the direction indicated by the arrow R2.It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Figure 2
[0039] In the description of the embodiments of the present application, please refer to Figure 2 and Figure 3 , the front-rear direction is the direction indicated by the arrow R1 in Figure 2 and Figure 3 .
[0040] In the description of the embodiments of the present application, please refer to Figure 3 , the left-right direction is the direction indicated by the arrow R3 in Figure 3 .
[0041] As part of the inventive concept of the present application, before describing the embodiments of the present application, the reasons why the existing test equipment in the related art is difficult to obtain relatively objective test results in the original running test process are analyzed, and the technical scheme of the embodiments of the present application is obtained through reasonable analysis.
[0042] In the related art, a test device includes a counting device, and a subject is usually required to measure the number of leg lifts of the subject within a certain time in a standing state to complete a step test, and the test device can only measure the number of leg lifts of the subject during the step test, but cannot monitor the test state of the subject. When the subject repeatedly lifts the leg while sitting on a seat, the test device can still count the number of leg lifts, but such a counting result cannot objectively reflect the true level of the step test of the subject, and the objectivity of the step test result is poor.
[0043] In view of this, the embodiment of the present application provides a health assessment chair assembly, please refer to Figures 1-4 , comprising an assessment chair assembly 1, a first sensor assembly 2, a second sensor assembly 3 and a controller. The first sensor assembly 2 is configured to monitor the sit-stand state of the subject. The second sensor assembly 3 is configured to measure the number of leg lifts of the subject in a step test mode. The controller is configured to obtain the number of sit-stand times of the subject during a sit-stand test and the time used in the sit-stand test according to the sit-stand state of the subject in a sit-stand test mode, and exit the step test mode when the controller determines that the subject is in an abnormal step state according to the sit-stand state of the subject in the step test mode. In this structure, the sit-stand state of the subject is monitored by the first sensor assembly 2, and the controller can obtain the number of sit-stand times during the sit-stand test and the time used in the sit-stand test according to the sit-stand state of the subject, so that the subject completes the sit-stand test. The sit-stand state of the subject is monitored by the first sensor assembly 2 used for the sit-stand test, and when it is detected that the subject is in an abnormal step state, the step test mode is exited, and the number of leg lifts of the subject is no longer counted by the second sensor assembly 3, so that the subject can be prevented to a certain extent from counting the number of leg lifts in an abnormal step state, the objectivity of the test result of the step test is high, a more objective test result of the step test can be obtained, and the possibility of the subject performing the step test in an abnormal step state can be reduced. The first sensor assembly 2 used for the sit-stand test is used for monitoring the abnormal step state, and no additional monitoring device is needed to monitor the abnormal step state of the subject, which reduces the cost and makes the structure of the assessment chair assembly more compact. The sit-stand test is performed by the first sensor assembly, which reduces the interference of human factors during the sit-stand test, and makes the sit-stand test result more objective.
[0044] It should be explained that the step test usually needs to be completed by the subject in a standing state, and when the subject sits on a seat, the subject is in an abnormal step state, and the measured number of leg lifts cannot objectively reflect the test level of the step test of the subject. The subject just contacts the assessment chair assembly 1 to the subject completely sitting on the assessment chair assembly 1 all belong to the abnormal step state.
[0045] It is to be explained that the sit-to-stand state includes the standing state and the sitting state. The subject can be in the standing state or the sitting state.
[0046] It is to be explained that the sit-to-stand times include the standing times and the sitting times. Exemplarily, five sit-to-stand times mean that both the standing times and the sitting times are five times.
[0047] In an embodiment, referring to Figure 4 , the first sensor assembly 2 is at least partially mounted on the assessment chair assembly 1, and the first sensor assembly 2 is configured to monitor the sit-to-stand state of the subject relative to the assessment chair assembly 1. In this structure, the sit-to-stand test is performed by using the assessment chair assembly 1, and the first sensor assembly 2 and the second sensor assembly 3 are both located near the assessment chair assembly 1, which facilitates the cooperation and joint action of the first sensor assembly 2 and the second sensor assembly 3, so as to reduce the possibility of the subject performing the leg lifting count in the abnormal stepping state, and the result of the in-place stepping test is more objective.
[0048] In an embodiment, the controller is connected with the first sensor assembly 2 and the second sensor assembly 3 respectively. In this way, the controller is connected with the first sensor assembly 2 to receive the sensing signal of the first sensor assembly 2, and the controller is connected with the second sensor assembly 3 to receive the signal triggered by the second sensor assembly 3 and count the leg lifting times of the subject according to the signal triggered by the second sensor assembly 3.
[0049] In an embodiment, when the stepping test mode is entered, the second sensor assembly 3 can count the leg lifting times of the subject.
[0050] In an embodiment, when the stepping test mode is exited, the counting of the leg lifting times of the subject by the second sensor assembly 3 is stopped.
[0051] In an embodiment, referring to Figures 1-4 , the assessment chair assembly 1 has a seating area 11 for the subject to sit down.
[0052] In an embodiment, referring to Figures 1-4 , the health assessment chair assembly further includes a bearing area 4 for bearing the feet of the subject, and the bearing area 4 is located below the seating area 11. In this way, the feet of the subject can be more conveniently stepped on the bearing area 4.
[0053] In an embodiment, the first sensor assembly 2 comprises a first pressure sensor 21 for measuring the pressure applied by the subject to the seating area 11 and a second pressure sensor 22 for measuring the pressure applied by the subject to the load bearing area 4; the controller is configured to determine the number of sit-to-stand movements of the subject during the sit-to-stand test and the time taken for the sit-to-stand test based on the pressure measured by the first pressure sensor 21 and / or the pressure measured by the second pressure sensor 22 in the sit-to-stand test mode, and to exit the step test mode when the controller determines that the subject is in the step abnormal state based on the pressure measured by the first pressure sensor 21 and / or the pressure measured by the second pressure sensor 22 in the step test mode. In this way, the pressure applied by the subject to the seating area 11 is measured by the first pressure sensor 21 and the pressure applied by the subject to the load bearing area 4 is measured by the second pressure sensor 22, the seating area 11 is for the subject to sit down and the load bearing area 4 is for the subject to place his feet, both of which are related to the sit-to-stand state of the subject, and the controller can more accurately monitor the sit-to-stand state of the subject through the first pressure sensor 21 and the second pressure sensor 22, so that the number of sit-to-stand movements of the subject measured in the sit-to-stand test and the time taken for the sit-to-stand test are more accurate, and since the pressure measured by the first pressure sensor and the pressure measured by the second pressure sensor can more accurately monitor the sit-to-stand state of the subject, the controller can more accurately determine whether the subject is in the step abnormal state.
[0054] In an embodiment, when the subject is in the step abnormal state, the pressure measured by the first pressure sensor 21 is greater than 0, and / or the pressure measured by the second pressure sensor 22 is less than a first preset pressure. The first preset pressure is the maximum value of the pressure measured by the second pressure sensor 22 under a preset condition, and the preset condition is that the subject stands on the load bearing area 4. In this way, by comparing the corresponding pressure value with the measured pressure value, all states of the subject from contacting the evaluation chair assembly 1 to sitting down to the evaluation chair assembly 1 are included in the monitoring of the step abnormal state, most possible step abnormal states can be monitored, and the objectivity of the step test is avoided by the subject repeatedly lifting his legs while sitting on the evaluation chair assembly 1.
[0055] It needs to be explained that when the pressure measured by the first pressure sensor 21 is greater than 0, the subject is most likely to contact the seating area 11 and not in a standing state, which is not the state of the subject in the step test, and can be determined as a step abnormal state. The first preset pressure is the maximum value of the pressure indicated by the second pressure sensor 22 when the subject stands on the load bearing area 4, and the pressure measured by the second pressure sensor 22 is less than the first preset pressure, which means that the subject is most likely to support the force with other parts and not in a standing state, which is not the state of the subject in the step test, and can be determined as a step abnormal state.
[0056] It is to be explained that, during the switching process from the sitting state to the standing state of the subject, the pressure measured by the second pressure sensor 22 gradually increases, the pressure indicated by the second pressure sensor 22 reaches a maximum value, and the subject is completely standing on the load area 4.
[0057] In an embodiment, referring to Figures 1-4 , the controller is a data acquisition and analysis module 6, which can be used to collect signals of the first sensor assembly 2 and the second sensor assembly 3.
[0058] In an embodiment, the evaluator can input the basic information of the subject, such as name and age, through the data acquisition and analysis module 6.
[0059] In an embodiment, the first pressure sensor 21 and the second pressure sensor 22 are both flexible pressure sensors.
[0060] In an embodiment, referring to Figure 3 , the first pressure sensor 21 is installed on the seating area 11, and the second pressure sensor 22 is installed on the load area 4. In this way, the first pressure sensor and the second pressure sensor can directly measure the corresponding areas.
[0061] In an embodiment, the step of performing the sit-to-stand test by the first pressure sensor 21 and the second pressure sensor 22 includes:
[0062] When the subject sits on the evaluation chair assembly 1, the subject alternately stands and sits to perform the sit-to-stand test. During the sit-to-stand test, when the pressure indicated by the first pressure sensor 21 is less than the second preset pressure, the timing starts. After the timing starts, when the condition for stopping the sit-to-stand test is triggered, the sit-to-stand test is stopped, and the number of times that the pressure measured by the first pressure sensor 21 reaches the second preset pressure, the number of times that the pressure indicated by the second pressure sensor 22 reaches the first preset pressure, and the time length from the timing start time to the timing end time are output. The second preset pressure is the maximum value of the pressure indicated by the first pressure sensor 21 in the state that the subject sits on the evaluation chair assembly 1. The timing end time is determined according to the condition for stopping the sit-to-stand test that is triggered.
[0063] In this way, by comparing the pressure indicated by the first pressure sensor 21 with the second preset pressure and comparing the pressure indicated by the second pressure sensor 22 with the first preset pressure, the number of times of sitting and standing of the subject during the sit-to-stand test and the time length used for the sit-to-stand test are obtained.
[0064] It is to be explained that the number of times of sitting and standing is the number of times that the subject alternately stands and sits. When the pressure indicated by the first pressure sensor 21 reaches the second preset pressure once, the subject sits down once. When the pressure indicated by the second pressure sensor 22 reaches the first preset pressure once, the subject stands up once.
[0065] It is to be explained that when the subject switches from the standing state to the sitting state, the pressure indicated by the first pressure sensor 21 gradually increases to the second preset pressure; when the subject switches from the sitting state to the standing state, the pressure indicated by the second pressure sensor 22 gradually increases to the first preset pressure.
[0066] In an embodiment, the condition for stopping the sit-to-stand test is at least one of the following conditions:
[0067] The number of times that the pressure indicated by the first pressure sensor 21 reaches the second preset pressure and the number of times that the pressure indicated by the second pressure sensor 22 reaches the first preset pressure both reach a preset number of times after the timing starts; and
[0068] The stop sit-to-stand test signal is received after the timing starts.
[0069] It is to be explained that at the timing start moment, the pressure indicated by the first pressure sensor 21 is already less than the second preset pressure, and the number of times that the pressure indicated by the first pressure sensor 21 reaches the second preset pressure is not counted before the timing start moment. Exemplarily, before the sit-to-stand test starts, the subject sits on the assessment chair assembly 1, and the pressure indicated by the first pressure sensor 21 reaches the second preset pressure, which is not counted in the number of times that the pressure indicated by the first pressure sensor 21 reaches the second preset pressure. Specifically, after the subject stands up and sits down again after the timing starts, the pressure indicated by the first pressure sensor 21 reaches the second preset pressure for the first time.
[0070] In an embodiment, the preset number of times is five, when the number of times that the pressure indicated by the first pressure sensor 21 reaches the second preset pressure reaches five and the number of times that the pressure indicated by the second pressure sensor 22 reaches the first preset pressure reaches five, the subject has completed five standing and five sitting, and the sit-to-stand test ends. The timing end moment is the moment when the pressure indicated by the first pressure sensor 21 reaches the second preset pressure for the fifth time.
[0071] In an embodiment, the subject cannot complete the test due to other reasons (for example, the subject is unwell), the stop sit-to-stand test signal is triggered, the controller receives the stop sit-to-stand test signal, and the sit-to-stand test ends. The moment when the pressure indicated by the first pressure sensor 21 reaches the second preset pressure for the last time is the first moment, and the moment when the pressure indicated by the second pressure sensor 22 reaches the second preset pressure for the last time is the second moment. When the first moment is earlier than the second moment, the end moment is the second moment, and when the second moment is earlier than the first moment, the end moment is the first moment.
[0072] In an embodiment, the assessment chair assembly 1 has a stop button, and the stop sit-to-stand test signal can be triggered by the subject pressing the stop button.
[0073] In one embodiment, the evaluator actively triggers the stop sit-to-stand test signal through the data collection analysis module 6 according to the actual situation of the subject.
[0074] In one embodiment, the step of performing the sit-to-stand test through the first pressure sensor 21 and the second pressure sensor 22 further comprises performing a pre-test step before the timing starts, the pre-test step comprising:
[0075] causing the subject to stand up once and sit down once;
[0076] when the subject completes standing up once and sitting down once, the subject starts the sit-to-stand test and measures the number of times the subject sits down and stands up, and when the subject does not complete standing up once and sitting down once, the sit-to-stand test is stopped and an output of "failed test" is output.
[0077] It can be understood that the specific structure of the first sensor assembly 2 is not limited to including a first pressure sensor and a second pressure sensor.
[0078] In one embodiment, the first sensor assembly can be a displacement sensor, which senses whether the subject sits down and stands up through displacement changes.
[0079] In one embodiment, the first sensor assembly can be a camera, which acquires images through the camera to determine whether the subject sits down and stands up.
[0080] In one embodiment, please refer to Figures 1-4 , the second sensor assembly 3 has a detection portion 31 configured to measure the number of times the subject lifts the leg in the step test mode, and during the measurement of the number of times the subject lifts the leg, the bearing area 4 is located between the detection portion 31 and the seating area 11 along the arrangement direction of the detection portion 31 and the seating area 11. In this way, when the subject's foot is supported on the bearing area 4, the subject faces the detection portion 31, and the subject alternately stands up and sits back to complete the sit-to-stand test, and the subject stands up and lifts the leg forward to complete the step test, and the step test and the sit-to-stand test can share the bearing area 4 for bearing the subject's foot to stand up, on the one hand, the space of the evaluation chair assembly is fully utilized, the overall structure is relatively compact, and the occupied space is saved, on the other hand, the subject can more conveniently perform the step test and the sit-to-stand test.
[0081] It should be noted that the step test is usually a two-minute step test, that is, the number of times the subject lifts the leg during the two-minute step test is measured.
[0082] In one embodiment, please refer to Figures 1-4The second sensor assembly 3 comprises a support component 32 and a sensor body 33. The support component 32 is pivotally connected to the assessment chair assembly 1. The sensor body 33 comprises a first sub-sensor 331 and a second sub-sensor 332 arranged oppositely. The first sub-sensor 331 is connected to one of the support components 32, and the second sub-sensor 332 is connected to the other support component 32. When the subject is at least partially positioned between the first sub-sensor 331 and the second sub-sensor 332, the sensor body 33 triggers a counting signal. In this way, the sensor body 33 is installed on the support component 32 at a suitable height position. Each time the subject lifts a leg to the first sub-sensor 331 and the second sub-sensor 332, the counting is performed once, thereby completing the measurement of the number of leg lifts in the step test.
[0083] In an embodiment, referring to Figures 1-4 The first sub-sensor 331 and the second sub-sensor 332 each have a detection portion 31.

One end of the second connecting rod 322 is connected to the sensor body 33, and the other end of the second connecting rod 322 is movably arranged in the assessment chair assembly 1. In this way, the height of the sensor body 33 connected to the second connecting rod 322 can be adjusted by rotating the first connecting rod 321, thereby being suitable for different subjects to measure the number of leg lifts to complete the step test.
[0085] In an embodiment, referring to Figures 1-4 The assessment chair assembly 1 is formed with a guide device 12. Each of the second connecting rods 322 is provided with the guide device 12. The guide device 12 is located at the bottom of the assessment chair assembly 1, and the other end of the second connecting rod 322 is movably arranged in the guide device 12. In this way, the guide device 12 has a certain guiding effect on the second connecting rod 322, preventing the second connecting rod 322 from deviating during movement.

[0090] In one embodiment, the second locking mechanism can be a motor with a self-locking mechanism, the motor drives the first link 321 to rotate, when the sensor body 33 is adjusted to the corresponding required height, the motor stops driving, the first link 321 stops rotating, and the sensor body 33 is maintained at the corresponding required height. Exemplarily, the motor can be a worm gear deceleration motor.

[0116] In an embodiment, the health evaluation chair assembly further comprises a stop button arranged on the armrest 14 and used for triggering a stop sitting test signal.
[0117] The health evaluation chair assembly of the embodiment of the present application will be described in further detail in combination with a specific application example.
[0118] The five sitting test processes please refer to Figure 6 , which include:
[0119] Step 501, inputting the identity information of the subject.
[0120] The evaluator inputs the identity information of the subject in the data acquisition and analysis module 6.
[0121] Step 502, pre-testing the subject to make the subject try to stand up and sit down.
[0122] The evaluator selects the five sitting test test items. The voice prompt is “Please place your hands in front of your abdomen, straighten your back, and place your feet apart with a shoulder width. You can also place them slightly forward and backward to facilitate standing up. When standing up, the knee joint should be straight. Please try to stand up once and sit down once. You cannot use your hands for help. If you cannot complete the initial test or need help, please press the stop button on the left armrest 14 of the chair”. Those who cannot complete the initial test or need help will terminate the test once the “stop” button is pressed. This is a pre-test before the formal test. Whether the subject has sat down or stood up can be monitored through the first pressure sensor 21.
[0123] Step 503, judge whether the subject completes the pre-test, i.e. whether completes once standing and once sitting. If the subject does not complete the pre-test of once standing and once sitting, execute step 504. If the subject completes the pre-test of once standing and once sitting, execute step 505.
[0124] Step 504, output failure to perform the test.
[0125] Step 505, the formal test begins, the pressure measured by the first pressure sensor decreases from the second preset pressure, and the timing and counting begin.
[0126] The voice prompt is "please do so 5 times of standing and sitting, and try to be as fast and continuous as possible, and do not rely on the help of hands." At this time, the stopwatch is timed, and the number of times of standing and the number of times of sitting of the subject are recorded.
[0127] Step 506, when the sit-stand test stops, judge whether the five times of sitting and the five times of standing are completed. If yes, execute step 507; if no, execute step 508.
[0128] Step 507, the first pressure sensor stops timing and counting, and outputs the time used for the five times of sit-stand test, i.e. the total time of the five times of sitting and the five times of standing.
[0129] From the first time the buttocks of the subject leaves the seat body 131 to the fifth time the buttocks sits on the seat body 131, this time is recorded as the time used for the five times of sit-stand test.
[0130] Successfully complete five times of sit-stand: from the first time the buttocks of the subject leaves the seat body 131, the "first pressure sensor 21 (flexible pressure sensor)" is triggered, and the timing begins, when the pressure measured by the first pressure sensor is less than the second preset pressure, the timing begins. The test sequence of the five times of sit-stand is: sit-stand, stand-sit, stand-sit, stand-sit, stand-sit. When the buttocks of the subject sits on the seat body 131 for the fifth time, the "first pressure sensor 21 (flexible pressure sensor)" counts 5 times, and the timing range is from the beginning of the formal test to the time when the pressure value of the "first pressure sensor 21 (flexible pressure sensor)" is less than the second preset pressure for the first time, and the timing end is the time when the pressure value of the "first pressure sensor 21 (flexible pressure sensor)" reaches the second preset pressure for the fifth time.
[0131] Step 508, output the number of times of sitting and the number of times of standing and the time used for the sit-stand test.
[0132] Incomplete five times of sitting due to other reasons: from the first assessment object buttocks off the seat body 131, trigger "first pressure sensor 21 (flexible pressure sensor)", timing starts, when the first pressure sensor 21 measured pressure is less than the second preset pressure, trigger timing starts. If the evaluation object (subject) can't continue due to other reasons (such as illness), tell the evaluator, the evaluator manually triggers the data acquisition and analysis module 6, stop sitting test. At this time, the data acquisition and analysis module 6 makes a judgment, stop the test, judge whether the last time is "first pressure sensor 21 (flexible pressure sensor)" or "second pressure sensor 22 (flexible pressure sensor)", when the first pressure sensor 21 measured pressure reaches the second preset pressure, the first pressure sensor 21 is triggered, when the second pressure sensor 22 measured pressure reaches the first preset pressure, the second pressure sensor 22 is triggered. If the last trigger is "first pressure sensor 21 (flexible pressure sensor)", output "first pressure sensor 21 (flexible pressure sensor)" and "second pressure sensor 22 (flexible pressure sensor)" trigger times, the number of times the first pressure sensor 21 is triggered is the number of times the subject sits down, the number of times the second pressure sensor 22 is triggered is the number of times the subject stands up, the starting point of timing is the first "first pressure sensor 21 (flexible pressure sensor)" pressure value changes (pressure value becomes smaller) starts, the ending point of timing is the last time "first pressure sensor 21 (flexible pressure sensor)" reaches the second preset pressure. If the last trigger is the second pressure sensor 22, output the first pressure sensor 21 and the second pressure sensor 22 trigger times, the starting point of timing is the first "first pressure sensor 21 (flexible pressure sensor)" pressure value changes (pressure value becomes smaller) starts, the ending point of timing is the last time the second pressure sensor 22 reaches the first preset pressure.
[0133] Count: record the number of stand-sit of the evaluation object (achieved by flexible pressure sensor), that is, record the number of times the subject stands up and sits down.
[0134] Complete 1 "sitting": that is, the "first pressure sensor 21 (flexible pressure sensor)" pressure value changes from 0 to the second preset pressure, and then changes from the second preset pressure to 0. The definition of the second preset pressure is shown in the foregoing content.
[0135] Complete 1 "stand": that is, the "second pressure sensor 22 (flexible pressure sensor)" pressure value changes from the minimum value to the first preset pressure, and then changes from the first preset pressure to the minimum value. The definition of the first preset pressure is shown in the foregoing content; the minimum pressure value is the pressure value felt by the second pressure sensor 22 when the evaluation object is in a resting state sitting on the chair.
[0136] In an embodiment, the subject's identity information is obtained during the grip strength measurement and heart rate measurement process, for example, the identity information (such as age, gender, disease condition, etc.) of the elderly (subject) is input in the grip strength test and heart rate monitoring "data collection and analysis module 6". The subject's safe heart rate range is obtained according to the subject's identity information, which can be calculated using the individualized maximum heart rate algorithm. Voice prompt: "Please keep your sitting posture, with your knees and hips bent at 90 degrees, your feet naturally flat on the ground, your forearms in a neutral position and your shoulders kept in a retracted position, with your elbows bent at 90 degrees. Limit the range of motion of your wrists to within 30 degrees, then squeeze the grip strength sensor 51 with maximum force. Please squeeze the grip strength sensor 51 with maximum force again. Please squeeze the grip strength sensor 51 with maximum force again". In the grip strength test mode, the grip strength sensor 51 measures the grip strength of the subject, and the heart rate sensor 52 measures the heart rate of the subject. The computer displays general information, grip strength, heart rate, grip strength level, etc. Based on the comparison of the heart rate value and the safe heart rate range, if the heart rate measured by the heart rate sensor 52 is greater than or equal to the maximum value of the safe heart rate range, the grip strength test mode is exited, the grip strength sensor 51 is temporarily "disabled", the grip strength test of the elderly is stopped and an alarm information is issued. Output value: ① Successful three times test: select the maximum grip strength of the three tests as the result output. Grip strength classification: according to the age, gender and grip strength of the evaluation object, the grip strength level (weak, medium, strong) is judged. ② Termination due to heart rate greater than or equal to the maximum heart rate value of the safe heart rate range: output the number of grip strength tests, and the corresponding grip strength and classification.
[0137] Heart rate during exercise: A person's maximum heart rate (maximum value of the safe heart rate range) is about 220 minus age, and the best effect is achieved when the maximum heart rate during exercise is 65%-85%, and the heart rate of people over 60 years old during exercise should be controlled at 104-135 times / minute, but if the person has heart disease, the heart rate during exercise should be controlled at 55%-75% of the maximum heart rate.
