[0003] Medical examination equipment is used for examination of physical functions. Such medical examination equipment includes nystagmus, electromyograph, respiratory function measuring device (hereinafter referred to as “spy mouth meter”) and the like.

[0004] The spy meter is a measuring device that measures the respiratory flow rate (respiration flow rate) of a subject and measures the vital capacity from the respiratory flow rate, and updates the display of changes in the respiratory flow rate with a recording curve called a spirogram. I will do it.

[0005] As an example of a spy meter, a flow meter for gas measurement that measures a flow rate based on a differential pressure before and after a laminar flow resistor in a passage through which a gas flows using a pneumotach sensor (for example, Patent Document 1) Or a rotating body provided between a pair of deflecting members provided in the middle of the flow path and having eddy current or inspiration, and based on the rotational speed and direction of rotation of the rotating body by the vortex, A respiratory flow measurement device (for example, see Patent Document 2) that measures a flow velocity is known.

[0006] A respiratory function test (spirometry) using a snoirometer is a test that is always performed in the case of chronic respiratory diseases such as emphysema, bronchial asthma, and bronchiectasis. In recent years, the importance of spirometry has been recognized again as a test necessary for the diagnosis of chronic obstructive pulmonary disease (COPD), which is said to have millions of potential patients. ing. On the other hand, in daily medical checks such as training gyms, vital capacity, tidal volume, 1-second rate, residual volume, etc. are measured using a spirometer. [0007] When examining a subject's physical function, he / she is accompanied by a doctor / clinical laboratory technician / nurse! / Healthy medical staff, and the next action to be taken by the subject according to the test status and test result And give guidance. In response to this, the subject moves on to the next action according to the instructions and guidance of the staff.

[0008] For example, in the forced vital capacity test, first, the medical staff force the patient to perform at least three or more rest breaths, and after confirming a stable expiratory position with a snorogram, the rest expiratory position force is also the maximum inspiratory position. Inhale until. Then ask the patient to call at once, and ask the patient to continue the call effort for at least 6 seconds while monitoring the snorogram. Then, when the spirogram force plateau (the state in which the respiratory volume is unchanged and the curve is horizontal) is confirmed, the test is terminated. After that, the medical staff checks the validity and reproducibility of the spirogram, and if the test result is good, adopts the test result, and if it is not good, performs the test again.

FIG. 1 is a diagram showing an example of a schematic configuration of the spy meter 100, and FIG. 2 is a block diagram showing an example of a functional configuration of the spy meter 100. As shown in FIGS. 1 and 2, the spy meter 100 includes a respiratory flow meter 10 and a recording device 20.

The respiratory flow meter 10 is a functional unit that measures the respiratory flow rate of the user (subject), and includes a tubular body 11 and a holder unit 12 as shown in FIG. The tubular body 11 has a mouthpiece portion 13 that can be intubated into the oral cavity of the subject, and is formed of a cylindrical transparent resin, thereby forming a flow path through which the subject's breathing air flows.

The holder portion 12 is detachably formed on the tube body 11 and is provided with a flow meter for measuring the flow of respiratory air flowing through the tube body 11. The flow meter converts the measured airflow into an electrical signal and outputs it to the recording device 20. As the flow meter, a known technique can be adopted as appropriate, for example, a pneumo tachograph or a hot wire flow meter. The pneumo-tachograph is a flow meter that measures the air flow by measuring the pressure difference from the inlet to the outlet of the tube 11, and the hot-wire flow meter changes the resistance value of the hot wire according to the temperature change caused by the air flow. This is a flow meter that measures airflow using In the present embodiment, a so-called airflow type flow meter may be adopted. A flow type flow meter such as a Benedict loss type or a bellows type may be adopted.

[0040] The test subject (hereinafter referred to as "patient" as appropriate) includes the mouthpiece part 13 of the respiratory flow meter 10, and performs rest breathing, inhalation to the maximum inspiratory position, exhalation to the maximum expiratory position, etc. Examination of respiratory function by taking appropriate behavior. The respiratory function test result is displayed as a snorogram on the display unit 23 of the recording device 20. A spirogram is a curve that records changes over time in respiratory volume (lung volume), and a respiratory function test is performed while monitoring this snoogram.

According to FIG. 2, the recording device 20 includes a CPU (Central Processing Unit) 21, an operation unit 22, a display unit 23, an audio output unit 24, a data input unit 25, a ROM (Read Only Memory) 26, a RAM ( Random Access Memory) 27 and storage unit 28 are provided. The recording device 20 may be configured by a general personal computer, or may be formed integrally with the respiratory flow meter 10.

The CPU 21 that is the guiding means and the guiding function is a functional unit that inputs and outputs instructions and data to each functional unit constituting the recording device 20. More specifically, the CPU 21 reads a program stored in the ROM 26 and the storage unit 28 in accordance with an operation signal input from the operation unit 22, and executes processing according to the program. Then, display data for displaying the processing result is output to the display unit 23, and a screen according to the display data is displayed on the display unit 23. Further, the CPU 21 outputs the audio data of the processing result to the audio output unit 24 and causes the audio output unit 24 to output the processing result as audio.

[0043] The operation unit 22 includes a key group necessary for character input such as numbers, kana, and alphabets, function selection, and the like, and a pointing device such as a mouse. The position information etc. is output to CPU21.

[0044] The display unit 23, which is a display guiding means, is an LCD (Liquid Crystal Display) or CRT (Cathode

A display panel such as a ray tube) is configured, and various screens based on display data input from the CPU 21 are displayed on the display panel.

[0045] The audio output unit 24, which is an audio guiding means, is configured to include a DZA converter, a speaker amplifier, and a speech force. The audio output unit 24 performs DZA conversion on the audio data (digital) output from the CPU 21 to generate an audio signal (analog), and amplifies the audio signal. Then, the amplified audio signal is output to a speaker, and the audio is output from the speaker.

The data input unit 25 includes a DZA converter, and DZA converts the respiratory flow electrical signal input from the respiratory flow meter 10 and outputs it to the CPU 21.

The ROM 26 is composed of a nonvolatile semiconductor memory, and stores an initial program for performing various initial settings, hardware inspections, loading of necessary programs, and the like. The RAM 27 is composed of rewritable semiconductor elements, and temporarily holds various programs executed by the CPU 21 and data related to the execution of these programs.

FIG. 3A shows an example of the data configuration of the RAM 27. According to the figure, RAM2 7 stores patient information 270 and examination data 272 having respiratory flow data 274 and respiratory volume data 276.

[0049] Patient information 270 is data such as a subject's name, ID number, age, sex, height, weight, and disease name, and is input by a user (subject). The respiratory flow data 274 is a series of continuous data obtained by accumulating the respiratory flow measured by the respiratory flow meter 10. The CPU 21 functioning as an examination unit calculates the respiratory volume by integrating the respiratory flow data 274 and stores it in the RAM 27 as the respiratory volume data 276. The snorogram is displayed by plotting the respiratory volume data 276 on the display unit 23 as needed.

[0050] The storage unit 28 is a functional unit that reads / writes data from / to a magnetic or optical storage medium, and includes a HDD (Hard Disk Drive) or the like. FIG. 3B is a diagram showing an example of the data configuration of the storage unit 28. According to the figure, the storage unit 28 stores a forced vital capacity test guidance program 280, a test history database (hereinafter referred to as “DB”) 284, and reference data 282 having a stratified test result DB2 86. ing.

[0051] The forced vital capacity test guidance program 280 is a program for realizing a forced vital capacity test guidance process (see FIG. 4). When the CPU 21 detects that an instruction to start the forced vital capacity test is input from the operation unit 22, the CPU 21 reads the forced vital capacity test guidance program 280 from the storage unit 28, and starts the forced vital capacity test guidance process. The forced spirometry test guidance program 280 can be downloaded via a flexible storage medium (for example, a CD-ROM) or a public network (including the Internet).

[0052] The examination history DB 284 is a DB that stores respiration volume data (past data) examined in the past so as to be searchable in association with the name or ID number of the subject. The CPU 21 searches the examination history DB 284 for past data associated with the name or ID number of the patient information 270. If the test history DB 284 stores past data of the subject, the breath volume data is read out and displayed on the display unit 23 as a reference snorogram RSG shown in FIG. Means are realized.

[0053] Results of stratified examination DB286 is based on respiratory volume data (standard data) pre-statistically classified by age, sex, and body type, such as early 30s, male, height 175-180cm, weight 65-75Kg. ) Is stored and stored in a searchable manner. CPU21 detects past data of subjects. 查 History Respiration volume data corresponding to gender, height, and weight of patient information 270 is read from the stratified test result DB286 when the force is not stored in the DB284, and the reference spirogram RSG is displayed on the display unit 23. By displaying, a statistical data display means is realized.

[0054] When displaying the respiratory volume data read from the examination history DB 284 or the stratified examination result DB 286, the CPU 21 displays a resting respiratory range R1 that is displaced with a constant amplitude in the respiratory volume data. Following this rest breathing range R1, the maximum inspiratory range R3 that is displaced to the maximum value MAX in the respiratory flow data and the maximum expiratory range R5 that is displaced from the maximum value MAX to the minimum value Ml N in the respiratory flow data are analyzed, Lines RL1 to RL9 are displayed so as to delimit these ranges.

[0055] And between the shoreline RL1 to RL3 (rest breathing range R1), "normal breathing", between the shoreline RL3 to RL5 (maximum inspiration range R3), to the shoreline RL5 to RL7 A series of test steps (test steps) to be performed by the subject, such as “exhale” and “normal breathing” between the shore lines RL7 to RL9. Display it.

Next, referring to the display examples of FIGS. 5 to 7, the content of the forced vital capacity test guidance process of the snoirometer 100 will be described using the flowchart of FIG. In the following, an example of application when the spirometer 100 is used for a forced vital capacity test will be described, but it may be applied to other respiratory function tests such as a vital capacity test.

First, the CPU 21 stores the name, ID number, age, sex, height, weight, disease name, and the like input by the user in the RAM 27 as patient information 270 (step Sl). Then, based on the name or ID number of the patient information 270, the past data of the same patient is searched from the examination history DB 284 (step S3).

When the past data of the same patient is stored in the examination history DB 284 (step S5; YES), the CPU 21 reads the past data and displays it on the display unit 23 (step S7). If past data of the same patient has not been stored (step S5; NO), respiratory volume data based on gender, height, weight, etc. of patient information 270 is read out from the stratified examination result DB286 and displayed. Display on part 23 (step S9). [0059] The CPU 21 displays the reference spirogram RSG of the respiratory volume data read in steps S5 and S9 and the prior instructions A1 to A7 as shown in FIG. In this way, by displaying the reference spirogram RSG and prior instructions A1 to A7, the subject (patient) can confirm the invocation and inhalation guideline and the inspection process in advance. it can.

[0060] Then, the CPU 21 induces the start of rest breathing by displaying the instruction message MS1 “Release power and breathe slowly” as shown in FIG. 5 on the display unit 23 (step Sl l ). Then, the acquisition of the respiratory flow data 274 output from the respiratory flow meter 10 is started (step S13), and the respiratory volume data 276 calculated from the respiratory flow data 274 is plotted and displayed on the display unit 23 so as to be superimposed. The CPU 21 of the means superimposes the reference spirogram RSG on the spirogram SG as shown in FIG. (Step S15).

[0061] In addition, by displaying the marker C in the latest respiratory volume data 276 calculated from the respiratory flow data 274, it is clearly indicated which process is in the entire process. This allows the subject to know in advance what kind of breathing should be performed next, so that the tension and anxiety about the subject's examination can be eased.

[0062] The CPU 21 as a determination means waits until the amplitude of the respiratory volume data 276 continues to stabilize three times, and when the amplitude stabilizes three times, the rest breathing in the examination process is performed three times. If it is determined that it has been performed (step S17; YES), and according to the determination result, as shown in Fig. 6, the instruction message MS3 is displayed on the display unit 23. Inspiratory induction is performed in real time in accordance with rest breathing (step S 19

) o

[0063] Then, the maximum value MAX in the reference data 282 (past data or standard data) read in step S7 or S9 is extracted, and the ratio of the current respiratory volume data 276 to the maximum value M AX is calculated. . Then, the display of the ratio calculated as the reaching condition and the further inhalation instruction display are performed by the instruction message MS5, for example, “95% of the previous time. S23). In this way, a means for inducing reaching conditions is realized.

[0064] Subsequently, the process waits until the current respiratory flow rate data 274 is "0". The CPU 21 indicates that the respiratory flow data 274 has become “0”, that is, the subject's inhalation reaches the maximum inspiratory level. If it is determined that it has reached (step S25; YES), the instruction message MS5, such as “Next will exhale!”, Is displayed in real time in accordance with the subject's inhalation. (Step S27).

[0065] Then, for example, after displaying an instruction to start an effort exhalation with the instruction message MS9, "Please vomit!" (Step S29), the reference data 282 read in Step S7 or S9 (Past data or standard) The minimum value MIN in the data) is extracted, and the ratio of the current respiratory volume data 276 to the minimum value MIN is calculated. The calculated ratio is displayed as a breathing level by the indicator IDC as shown in FIG. 8 (step S3 Do)

[0066] Next, after a further call is guided by the instruction message MS11 such as "Let's do a little more! Good luck!" (Step S33), the process waits until the current respiratory flow data 274 becomes "0". If it is determined that the respiratory flow data 274 has become “0”, that is, that the call of the subject has reached the maximum expiratory position (step S35; YES), the apparatus waits for 3 seconds (step S37). Note that this waiting time can be changed as appropriate. For example, it may be set shorter depending on the disease name in the patient information 270! /.

[0067] The CPU 21 calculates the difference between the maximum value and the minimum value in the respiratory volume data 276 as the forced vital capacity, displays the test result on the display unit 23, and then ends the forced vital capacity test guidance process. In the display of the test result, if the CPU 21 determines that there is past data in step S5, the result of comparison with both the past data and the standard data is, for example, “64% of the normal standard. Test results such as “114% improved by 14%” Displayed on the display unit 23 as S13. If past data is weak, display the result compared with the standard data effort vital capacity.

[0068] Further, the CPU 21 which is the validity judgment means, the comparison judgment means, and the validity judgment time guidance means judges the validity of the inspection result according to the following judgment criteria and displays it on the display unit 23.

(1) Whether the slope of the respiratory flow data 274 at the time of maximum inspiration and forced expiration is greater than or equal to the default value (2) If noise occurs in the entire respiratory flow data 274! (3) Is the forced vital capacity of the respiratory volume data 276 below the forced vital capacity of the reference data 282 by a predetermined value or more?

If the criteria (1) and (2) are satisfied, the CPU 21 has the maximum inspiration, the start of the call is good, the peak is obtained early in the forced expiration, and the maximum call It is determined that a reasonable test result has been obtained as a result of the effort of the mood and the occurrence of archfeet due to coughing and vocalization. Depending on the result of the decision, for example, “The best test result was obtained. I did my best.”, “When I cried out, I felt cough or voice.” “When I cried out, momentum. “Let ’s try to do a little more,” he said.

[0069] Also, if the criterion (3) is satisfied, it is assumed that the test result has a reasonable force. For example, "Check the test method and perform the test again!" Display a message.

[0070] Further, at the time of the maximum expiratory position in the respiratory volume data 276, a sufficient call can be made based on a judgment criterion of whether or not there is a plateau of 2 seconds or longer (period in which the value of the respiratory volume data 276 is constant). When the appropriateness of whether or not it is possible is judged and V is not able to call enough without the plateau, for example, “Think, cut out! ”Let's continue” is displayed.

[0071] In addition, the validity is determined from the respiratory volume data 276 according to a criterion for determining whether or not the external volume is less than 5% of the forced vital capacity or 150ml, whichever is greater. The extrapolated air volume is the expiratory volume at the start point of the expiratory breath, where the spirogram SG extends the straight line of the maximum slope during forced expiratory and intersects the maximum inspiratory position as the expiratory start point of the forced vital capacity. ! If the external air volume is less than 5% of the vital capacity or 150ml, which is one of the larger! / 吐 values, for example, “When you exhale, you did not excrete!” As shown, the inspection process in which the defect has occurred is displayed.

[0072] After displaying the result of judgment of validity in this way, if the test result has a reasonable force, “Let's test again”, “When you vomit, let's vomit a little more momentum. "Instructions for re-inspection and instructions for indicating which process should be improved and the like are displayed. As a result, the subject modified which process and how in the next inspection. You can know what to do.

Note that the criteria for determining validity are not limited to those described above, and can be changed as appropriate. For example, a criterion for determination may be provided based on the disease name in the patient information 270. More specifically, for example, in the case of a patient with obstructive arousal disorder, the determination of the presence or absence of the plateau described above is not performed, and if the call continues for 6 seconds or more, a sufficient call can be made. It is determined that This makes it possible to perform an appropriate respiratory function test according to the patient's illness and symptoms.

As described above, according to the present embodiment, when there is past data of a subject, the past data is displayed as the reference spirogram RSG, and the spy under examination is superimposed on the reference spirogram RSG. Program SG is displayed. For this reason, the subject can confirm in which process the current breathing is in a series of steps of the forced vital capacity test. In addition, since the spirogram SG under examination can be compared with the reference snogram RSG, the subject can breathe using the spirogram RSG for reference as a guide.

In addition, the spy mouth meter 100 determines the progress of the examination based on the respiratory volume data 276 and displays an instruction message in accordance with the determination result. For this reason, the subject can check the maximum inspiration and forced expiration to be performed in real time in accordance with the examination by the displayed instruction message, and can appropriately perform the breathing in the examination process. Thus, since the snoirometer 100 can appropriately guide the respiration of the subject, the medical staff does not have to accompany the subject for the respiratory function test, and the burden on the medical staff can be reduced.

[0076] Further, by displaying the ratio with respect to the reference data 282 at the time of the maximum exhalation or the maximum inspiration, it is possible to indicate to the subject how much respiration is necessary. For this reason, it is possible to prevent the subject from remaining breathing and stopping breathing, and an appropriate test result can be obtained.

[Modification]

In the above-described embodiment, the power to display the breathing volume of the subject as the spirogram SG. The display is not limited to the example of FIGS. 5 to 8. For example, the graphic display as shown below It is good also as implement | achieving by. Figures 9 and 10 are display examples when the change in respiratory volume is displayed by rocket launch. In this case, Spirome The processing operation of the controller 100 will be briefly described with reference to the flowchart of FIG.

[0077] First, the CPU 23 performs the processing of steps S1 to S9 in FIG. 4 in the same manner as in the present embodiment, and the minimum value MIN, that is, the maximum expiratory level is determined from the reference data 282 read in step S7 or S9. Extract respiratory volume data. Then, the minimum value MIN is displayed as the firing target TG as shown in Fig. 9 (a).

[0078] Then, at the start of rest breathing in step S11, display SB1 as shown in Fig. 9 (a) is displayed on the display unit 23, and then acquisition of 247 of respiratory flow data is started (step S13). The CPU 21 displays the display SB3 shown in FIG. 9 (b) when the respiratory volume data 276 is increased, that is, during inspiration, and the display SB5 shown in FIG. 9 (c) when the respiratory volume data 276 is decreased, that is, when called. By displaying it, a graphic display is made so that the rocket expands and contracts according to the subject's breathing (corresponding to step S15).

[0079] Then, after three rest breaths are detected, the indication of the maximum inspiration is displayed by the display body SB7 and the instruction message MS3 as shown in Fig. 9 (d) (step S19). Next, after displaying the ratio for the reference data 282 with the display SB9 as shown in Fig. 9 (e) and the indication of further intake with the display SB11 as shown in Fig. 9 (f) (step When it is detected that the respiratory flow data 274 has become “0” (S21 to S23), preparation for the start of forced expiration is made by the display body SB13 of FIG. 9 (g) (step S27).

[0080] After the process of step S27, the CPU 21 displays the instruction message MS21 of "Launch!" As shown in FIG. 10, thereby instructing the start of forced expiration (step S29). Then, the display is updated as the display bodies SB15, SB17, SB19, SB21, and SB23 3 according to the increase / decrease of the respiratory volume data 276, so that the graphic display is made so that the rocket rises in accordance with the call of the subject.

[0081] Further, instructions for further calling are given by the instruction messages MS23 and MS25 (step S33), and after 3 seconds when the respiratory flow data 274 becomes "0", the instruction message MS27 and the test as shown in FIG. Result MS29 is displayed.

[0082] Thus, by displaying the subject's breathing volume using a rocket-shaped display instead of the spirogram SG, the resistance to respiratory function tests in pediatric patients and the like can be reduced, and the mental load can be reduced. It is possible to improve the motivation for. Note that the guidance method of the respiratory function test is not limited to the above-described embodiment, and for example, the following guidance method may be adopted as appropriate.

[0084] First, weighting may be performed on the maximum value MAX of the reference data 282 to be compared with the ratio displayed in step S21, and the ratio with respect to the weighted maximum value MAX may be displayed. More specifically, the maximum value MAX is multiplied by a predetermined value (for example, 1.1 times), and the ratio to the maximum value MAX is displayed. In this way, it is possible to obtain better test results by intentionally increasing the maximum inspiratory position targeted by the subject. Note that the same effect can be obtained by displaying the ratio in step S31 by applying the same weighting (for example, the minimum value MIN is multiplied by 0.9).

[0085] Further, as a result of comparison with the reference data 282 in steps S21 and S31, if the respiratory volume data 276 exceeds the maximum value MAX and the minimum value MIN of the reference data 282, the ratio is 100%. If it exceeds, a message such as “New record! New record!” May be displayed. Thereby, the motivation for the test of the subject can be improved.

[0086] In addition, the subject's respiration is induced by display on the display unit 23 such as an LCD. 1S For example, an electric light indicator in which LEDs (Light Emitting Diodes) are arranged is provided as the display unit 23, and the electric light indicator It is good also as displaying the fluctuation | variation of a respiratory volume by. In this case, the maximum value of the lightning indicator is set to correspond to the value of the maximum expiratory level of the reference data 282, and the range of the lightning indicator is adjusted. By adopting such a lightning indicator, the spy meter 100 can be miniaturized.

In addition, the instruction message displayed on the display unit 23 may be output as voice via the voice output unit 24. As a result, breathing can be instructed by voice, and the examination can be guided more accurately.

[0088] Further, the applicable range of the medical examination guidance apparatus of the present invention is not limited to a spy mouth meter that examines a subject's respiratory function, but an nystagmus that examines nystagmus based on the eye movement of the subject, It can also be applied to medical examination devices such as electromyographs that examine the movement of motor nerves based on the muscle activity of the subject's arms and legs. For example, in the case of an nystagmus, the eyeball of the subject is irradiated with infrared rays, and the reflected light power also determines the movement of the eyeball. Guide the movement of the examiner's line of sight. It can also be applied as an imaging guidance device that guides X-ray imaging using barium. In this case, the posture of the subject at the time of imaging is determined by analyzing the image data taken with a CCD camera or the like. Then, in accordance with the determination result, the subject guides the posture to be taken next. Thus, the medical examination guidance apparatus of the present invention can induce examinations of various body functions.
