DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a medical examination device that is used for medical examinations and includes an input device and an arithmetic processing device.

(Prior art and its problems) Generally, data regarding the health of a patient is obtained from data regarding lifestyle habits such as smoking and drinking through questionnaires and the like.

However, the data obtained from questionnaire surveys is crude and inaccurate, making it impossible to accurately assess health levels or provide appropriate guidance.

In addition, urine collection and auscultation are sometimes used, but in any case, comprehensive judgment and guidance cannot be made, and auscultation in particular takes time.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the present invention provides a blood A property detection means, a power detection means for detecting a light load power and a heavy load power by performing light load exercise and heavy load exercise until the patient's pulse reaches a set pulse rate, and detecting a resting blood pressure and a stress blood pressure. an input device comprising: a blood pressure detection means for detecting a light load; The degree of fatigue is calculated based on the maximum workload and the maximum workload under heavy load, and the blood properties, resting blood pressure, stress blood pressure, and fatigue level are calculated and compared with the data of a standard healthy person of the same sex and age as the examinee. , and an arithmetic processing device that arithmetic-processes a health index of a patient from these calculated values.

(Function) Therefore, when performing a medical examination using the medical examination device of the present invention, first, the blood property is detected by the blood property detection means, and then heavy load exercise and light load exercise are performed. The light load power and the heavy load power are detected, and the blood pressure detection means detects the resting blood pressure and the load blood pressure, and these data are input to the arithmetic processing device.

Then, the processing unit calculates the light load maximum workload and heavy load maximum workload based on the light load work rate and heavy load power, and further calculates the degree of fatigue based on the light load and heavy load maximum workload. Then, the blood properties, resting blood pressure, stress blood pressure, and fatigue level are compared with the data of a standard healthy person of the same sex and age as the patient, and a health index is calculated from these calculated values as a comparison index with the standard. Let's do it.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained.

As shown in FIG. 1, the health examination apparatus of this embodiment includes an input device 20 and a microcomputer 30.
and a display device 40 are the main components.

The input device 20 includes a keyboard 21, a sphygmomanometer 22 that detects the patient's pulse and blood pressure, an ergometer 23 that detects the work rate by performing gradual load exercise, and a blood property detector that detects blood properties. It is equipped with 24 and.

A recording device 50 is connected to the blood pressure monitor 22 and the ergometer 23, respectively.
2. When measuring with the ergometer 23, the recording device 50
When the IC card 60 is set in the
Data is now being entered.

The ergometer 23 used here is
It is a bicycle-type load training device that can apply a quantitative load, and is a gradual load type in which a constant load gradually increases over time regardless of the rotational speed of the pedals. Further, the initial load amount can be set arbitrarily.

This ergometer 23 has a built-in arithmetic circuit that calculates the power from the exercise time and the amount of work (load x travel distance), and the power is input to the IC card 60 as data.

The display device 40 is connected to the microcomputer 3
It displays data output from 0, and includes a screen display device 41 for displaying the data on a screen, and a printer 42 for printing out data.

Next, the body image diagnosis performed using the health examination device of this embodiment will be explained step by step (Second
(see figure).

Before making a diagnosis, prepare one IC card for each patient.

In addition, the IC card described below is the same as the IC card 6 above.
It indicates the same thing as 0, but the IC cards below have the code 60 because the input data is not the same.
Add a to i.

First, the patient's gender and age are entered into the IC card 60 using the keyboard 20 (Step 1).

Next, blood is collected (Step 2), and the lipids (total cholesterol, HDL cholesterol), nitrogen components (BUN), enzymes (GOT,
GPT, ALP, LDH), hemoglobin, glycated hemoglobin, and total bilirubin are measured using the blood property detector 24 (Step 3). The blood property detector 24 performs the following measurements during the blood property test.

Next, use the sphygmomanometer 22 to detect the maximum blood pressure and minimum blood pressure while at rest, as well as the pulse at rest, and record the data.
Data is input into the IC card 60a (Step 4).

Next, the ergometer 23 performs a gradually increasing load exercise until the set pulse is reached, and the blood pressure monitor 22
Detect load blood pressure and pulse (Step 5~
Step9).

This exercise is performed in two types, light load exercise and heavy load exercise, by changing the amount of load set at the start of exercise and the load that is gradually increased.

Then, the power when the set pulse rate is reached is detected in the case of light load exercise and in the case of heavy load exercise, and the light load power and heavy load power are detected by the IC card 60c,
Input data to 60e (Step 6, Step 8).

In addition, heavy-load exercise should be performed a certain period of time, for example, 10 minutes after the end of light-load exercise, and blood pressure measurement should be performed after light-load exercise and after heavy-load exercise (Step 7,
Step9).

Pulse measurement is carried out from before the start of the light load exercise to after the end of the heavy load exercise, and the pulses before the start of the light load exercise and before the heavy load exercise are input into the IC cards 60b and 60d (Step 5, Step 7).

The reason why the pulse rate is detected after the detection of the resting venous pulse and before the start of light-load exercise is to read subtle changes in the pulse rate if any work is performed during this period and obtain accurate data.

Then, the blood data measured by the blood property detector 24 is transferred to the IC card 60g using the keyboard 21.
Enter data into (Step 10).

Next, the input data of the IC card 60h is inputted to the microcomputer 30, arithmetic processing is performed based on each input data, and the calculated value is sent to the IC card 60h.
Input data to 0h (Step 11).

Next, after processing the input data and arithmetic processing results input to the IC card 60i based on the display program, the microcomputer 30
The data is output to the screen display device 41 and displayed on the screen (Step 12).

Displaying the arithmetic processing results on the screen display device 41 in this way makes it possible to consult with an advisor on the spot.

Furthermore, the input data of the IC card 60i and the arithmetic processing results may be output to the printer 42 and printed out on a suitable paper to create the health checkup card 43 (Step 13).

After the medical examination is completed, the IC card 60i is kept.

By storing data from several past health checkups in the IC card 60, it is possible to easily compare the current data with past data. In this case, by displaying current data and past data simultaneously at the screen display or printout stage, as in the medical examination card 43 shown in Figure 3, changes over time can be seen at a glance. You can also.

You can also delete the oldest data each time you enter new data.

The outline of the calculation process shown in FIG. 4 will be explained below.

Among the input data input to the IC card 60h, the maximum pulse rate is first estimated from standard data based on the sex and age (chronological age) of the patient (Step 111). Then, from this maximum pulse, the set pulse, the light load and heavy load power inputted from the ergometer 23 when the set pulse is reached, and the light load maximum work from the pulse before starting light and heavy load exercise inputted from the blood pressure monitor 22. and heavy load maximum workload are calculated (Step 112, Step 113), and the degree of fatigue (stamina) is further calculated from these light load and heavy load maximum workload (Step 114).

Next, the resting maximum blood pressure, stress blood pressure, fatigue level, and blood properties are compared with data of a standard healthy person of the same sex and age as the examinee, and a score is evaluated (Steps 115 to 118).

Finally, a healthy age is calculated from the resting systolic blood pressure evaluation score, stress blood pressure evaluation score, fatigue evaluation score, blood property evaluation score, and chronological age calculated by the score evaluation (Step 119).

Next, the content of the calculation process will be explained in detail.

The degree of fatigue is calculated as follows.

First, from the light load (heavy load) pre-exercise pulse H ₀ , the set pulse H ₁ , the maximum pulse Hmax, the light load (heavy load) power L ₁ , and the light load (heavy load) maximum power Lmax (reaching the maximum pulse) (see Figure 5).

Furthermore, the light load (heavy load) maximum work time (exercise time required to reach the maximum pulse rate) is calculated by adding the power at the start of exercise and the gradual increase in power due to the gradual increase in load to this light load (heavy load) maximum power. The light load (heavy load) maximum workload is calculated from the light load (heavy load) maximum work time and the light load (heavy load) maximum work rate.

Here, if the maximum workload for light loads is w ₁ , the maximum workload for heavy loads is w ₂ , the maximum workload for light loads is t ₁ , and the maximum workload for heavy loads is t ₂ , then the maximum workload w and the maximum workload t are As shown in Figure _{6 , the} relationship _between
It is expressed as

The degree of fatigue is expressed by the area surrounded by w=n+mt, w=n, and t=tm (predetermined work time).

In addition, in FIG. 6, the degree of fatigue in the case where t=tm and the exercise with the maximum amount of work is performed with a light load is shown by the sloped portion.

Furthermore, the slope m of the straight line w=n+mt indicates aerobic power, or endurance, and the intercept n indicates anerobic power, or muscle strength.

The score evaluation of resting maximum blood pressure, load blood pressure, degree of fatigue, and blood properties is performed based on comparative data using a standard value of 0 as shown in FIG. Regarding blood properties, total cholesterol, HDL cholesterol, BUN, GOT, GPT, ALP,
The evaluation score for each measurement value of LDH, hemoglobin, glycated hemoglobin, and total bilirubin is calculated, and the total score is used as the blood property evaluation score.

Note that the comparison data is stored in advance in the microcomputer for each gender. FIG. 7 is HLD cholesterol comparative data table 31.

Finally, the healthy age indicates what age the examinee's health level corresponds to in a standard healthy person, and is calculated based on the following formula.

Healthy age = chronological age + resting systolic blood pressure evaluation score + stress blood pressure evaluation score + fatigue evaluation score + blood property evaluation score x blood property evaluation index Note that the blood property evaluation index is age-balanced with respect to the blood property evaluation score. It is calculated based on age.

Furthermore, we can predict hyperlipidemia from resting blood pressure and stress blood pressure, and predict arteriosclerosis, heart disease, anemia, hypertension, diabetes, obesity, kidney disease, etc. from blood characteristics.
It is also possible to predict diseases such as hepatitis.

Here, blood properties will be explained for each measurement item.

(Total cholesterol) Cholesterol is mainly produced in the liver, and
Absorbed from animal foods ingested into the body. Too much cholesterol in the blood can cause obesity and arteriosclerosis.

Note that the standard value of cholesterol contained in blood is 130 to 250 mg/dl.

(HDL Cholesterol) HDL cholesterol is also called good cholesterol among cholesterols, and works to take in cholesterol from peripheral tissues such as blood vessels and transport it to the liver.When there is a lot of HDL cholesterol in the blood, it can lead to arteriosclerosis. In recent years, there has been a growing belief that this is difficult to achieve.

The standard value of HDL cholesterol contained in the blood is 30 to 80 mg/dl for men and 35 to 85 mg/dl for women.

(BUN) BUN (urea nitrogen) is a nitrogen compound (waste product) that is a metabolic product of protein, and is a test factor to determine whether the kidneys, which excrete nitrogen compounds as urine, are working normally.

The standard value of BUN contained in the blood is 8 to 23 mg/
It is dl.

(GOT) GOT (glutamate oxaloacetate transaminase) is contained in cells such as the heart, liver, and muscles, and is released into the blood when cells die and break down or when the cell membrane becomes permeable. It is a testing factor for infarction and acute hepatitis.

The standard value of GOT contained in blood is 5~
It is 40 units.

(GPT) GPT (glutamate pyruvate transaminase) is contained in liver cells and is a test factor for liver diseases.

The standard value of GPT contained in blood is 0~
It is 35 units.

(ALP) ALP (alkaline phosphatase) is contained in tissues throughout the body, but is particularly abundant in bones, liver, bile ducts, renal tubules, etc. When abnormalities occur in these cells, large amounts can be released into the blood. It flows out and is a test factor for diseases of the bones, liver, and biliary tract.

The standard value of ALP contained in blood is 3~
It has 11 units.

(LDH) LDH (lactate dehydrogenase) is widely distributed in tissues throughout the body and is a test factor for malignant tumors, blood diseases, heart diseases, and liver diseases.

The standard value of LDH contained in blood is 70~
It is 400 units.

(Hemoglobin) Hemoglobin is a substance that takes in oxygen from the air and is contained in red blood cells.When the amount of hemoglobin in the blood decreases, it causes anemia.

The standard value of hemoglobin in the blood for men is
13 to 18 g/dl, and 11 to 16 g/dl for women.

(Total bilirubin) A yellow pigment that is generated from hemoglobin in red blood cells and flows into the blood when red blood cells age and break down. If total bilirubin in the blood increases too much, jaundice results.

The standard value for total bilirubin in the blood is 0.1
~1.0mg/dl.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, an ergometer with a built-in arithmetic circuit for calculating the power was used as the power detection means, but the time data from the time detection device such as a stop switch that detects the time and the time data from the time detection device are used as the power detection means. An arithmetic device that takes this into account and converts it into a power may also be used.

Furthermore, a running belt type trade mill may be used instead of a bicycle type ergometer.

Further, in the embodiment, an IC card is used and a recording device is connected to input devices such as a blood pressure monitor and an ergometer, but data may be entered into the IC card using a keyboard without using a recording device. Alternatively, a floppy disk or cassette tape may be used instead of an IC card.

Furthermore, although the pulse is detected using a blood pressure monitor in the embodiment, it may be detected using other devices such as an electrocardiograph.

Moreover, the measurement items of blood properties are not limited to the examples.

In addition, in the examples, the health index is expressed as a healthy age, but it may be expressed as a value other than age. For example,
It may be expressed as a ratio of 100±α, where the standard health level is 100.

(Effects of the Invention) As explained above, since the medical examination device of the present invention is equipped with an arithmetic processing unit, error-free arithmetic processing results can be obtained in a short time. The health index calculated through arithmetic processing makes it possible to clearly understand numerically the health level of the patient based on the standard health level.

In addition, since it is equipped with blood property detection means,
Blood property data can be used to comprehensively and accurately determine the level of health, and furthermore, to predict diseases.

In addition, the processing unit calculates the maximum light-load workload and the maximum heavy-load workload based on the light-load power and heavy-load power obtained by performing light-load exercise and heavy-load exercise until the set pulse rate is reached. Therefore, it is not necessary to measure the maximum amount of work by exercising until the maximum pulse is reached, and the degree of fatigue can be detected in a short time.

In addition to the above-mentioned effects, in the example, since each data was recorded on the IC card,
It is not bulky and convenient to store, and can also record data from several health checkups.
Comparisons with past data can also be easily made.

Furthermore, in the embodiment, a recording device is connected to an input device such as a blood pressure monitor or an ergometer, and data detected by the input device is automatically read.
Because the data is entered into the IC card,
It is possible to shorten the time required for recording work.

Further, in the embodiment, since the load exercise is a gradually increasing load exercise, the degree of fatigue can be detected in a shorter time.
