Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biological information measuring device for measuring biological information such as blood pressure, electrocardiogram, pulse rate, oxygen saturation, etc. in addition to the respiratory function of a subject. The present invention relates to a biological information measuring device including a respiratory function measuring device such as a sleep apnea measuring device for measuring an apnea state, and a memory card used for the same.

[0002]

2. Description of the Related Art Heretofore, it has been known that when a relatively long apnea condition frequently occurs during sleep, oxygen in arterial blood is remarkably decreased, or abnormal heart rate is accompanied. The sleep apnea condition causes sleep to be shallow, and there is a problem that the subject falls into a drowsiness during the day. Such a sleep apnea syndrome test was performed by using sleep polysomnography to measure sleep apnea (such as apnea frequency), EEG, eye movements, and oxygen saturation. . As described above, since a large number of tests are performed, the subject must be hospitalized and tested, which is costly and time-consuming for the subject, and is usually performed due to the abnormal sleep environment of the hospital facility. There is a problem that it is difficult to obtain correct sleep test results in many cases in which sleep cannot be obtained. In recent years, there has been proposed a respiratory function measuring device capable of easily examining symptoms of sleep apnea in a more natural state without conducting an in-patient examination (Japanese Patent Application Laid-Open No. 63-158040).
No.).

Before returning this kind of respiratory function measuring device to home and sleeping, a thermistor for detecting a temperature change in the respiratory flow from the nose and a microphone for detecting a respiratory sound in the throat are provided on the body of the subject. Attach electrodes for heart rate detection, and convert the detected data of the thermistor, microphone and electrodes to respiratory rate, respiratory stop time and respiratory stop time information in the signal processing unit while sleeping, and convert this conversion information to the memory unit. Is stored as information over time.

[0004] In this way, the information relating to the respiratory rate, the respiratory stop time and the respiratory stop time are measured and stored in the memory of the respiratory function measuring apparatus, and the data processing computer connected to the respiratory function measuring apparatus measures the information. Since the storage data is received from the memory unit and analyzed based on the analysis program, it is possible to easily diagnose whether or not the patient has sleep apnea syndrome.

[0005] Further, there has been an apparatus which can perform an analysis process only with a measuring apparatus without using a separate computer.

[0006]

However, the above-mentioned conventional respiratory function measuring apparatus requires a separate computer, and if a general-purpose personal computer is used as the computer, the analysis program can be changed relatively easily. However, the analysis process could not be performed only by the apparatus itself.

In the case of an apparatus that performs analysis processing only with a measuring device without using a separate computer, it is necessary to use a uniform analysis program for the analysis processing. In order to change or add to the analysis, it is necessary to rewrite the analysis program stored in the ROM, and there is a problem that it is not easy to change or add the analysis contents.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a respiratory function measuring apparatus capable of easily changing or adding analysis contents in a main body of the apparatus and a memory card used for the apparatus. And

Analysis processing is performed by an analysis program read by the reading unit. Further, the memory card of the present invention is used by being loaded into the loading port of the biological information measuring device according to the first aspect, and at least an analysis program for data analysis is recorded.

[0010] With this configuration, an analysis program for analyzing desired data is recorded for each memory card, and the biological information is analyzed and processed based on the analysis program read from the memory card by the information reading unit, and parameters relating to the biological information are set. Therefore, even if a new analysis method is proposed or the required analysis method differs for each subject's symptoms, a new analysis method or change of the desired analysis program according to the subject to a memory card is required. And easy to add.

Preferably, the biological information measuring device of the present invention has a display unit for displaying analysis result data obtained by the analysis processing.

With this configuration, it is possible to diagnose the symptoms by displaying the analysis result data obtained by the analysis processing on the display unit.

Further, preferably, the biological information measuring device of the present invention has a data output unit capable of outputting analysis result data by the analysis processing.

With this configuration, it is possible to take out the analysis result data from the analysis processing from the data output unit.

Further, preferably, the biological information and / or the memory card in the biological information measuring device of the present invention are stored in the memory card.
Alternatively, a storage control unit for storing personal data of the subject is provided.

With this configuration, if the biometric information of the subject is stored in the memory card, it is not necessary to connect to a computer for performing more complicated data analysis.
It is possible to carry out the data analysis efficiently together with the data analysis of another subject at another place while carrying the memory card, and it is possible to easily manage the biological information of each subject with the memory card. If the personal data of the subject is stored in the memory card, the biological information of each subject can be easily managed in correspondence with the personal data of the subject.

Specifically, this operation unit is preferably rotatable in one direction and in the opposite direction so as to sequentially display the display contents of the display unit, and is operable in the pressing direction to select at least the display contents of the display unit. Configuration.

According to this configuration, since the operation unit combining the rotation direction operation and the pressing operation is used, the operability is good, and the space for the operation unit is reduced, so that the main body can be downsized. Further, since the display content of the display unit is sequentially displayed by operating the rotation direction of the operation unit, the display screen size of the display unit may be small, and the main body unit on which the display screen is provided can be downsized.

The arithmetic unit 87 has an arithmetic storage function of calculating the oxygen saturation, pulse rate, and the like at predetermined time intervals (for example, every 5 seconds) based on each oxygen saturation signal.
Each oxygen saturation signal waveform (pulse wave signal waveform) from the oxygen saturation finger sensor 2, a respiratory effort signal waveform from the chest belt 3,
A tracheal sound / snoring sound signal waveform from the microphone 4 and a respiratory temperature signal waveform from the flow sensor 5 are sequentially stored in the memory 89 as time measurement data as respective measurement data.

In the memory card 92, a desired analysis program can be registered. Simply by changing the memory card 92 and attaching it to the memory card connector 88, analysis processing is performed with analysis contents and analysis procedures based on different desired analysis programs. Like that. For example, in the analysis of sleep apnea syndrome, a new analysis method is proposed or a necessary analysis method is different for each symptom of the subject, so that it is indispensable that the analysis program can be rewritten. Examples of the analysis method for each subject include, for example, a case where the subject wants to inherit an analysis method used before using the present apparatus, or a case where the subject wants to delete an analysis item that the subject considers unnecessary (for example, an embodiment described later). 2 and the like in the first embodiment in which the position detection item is removed).

Detailed analysis data obtained from each sensor is required.
For example, the information obtained from the flow sensor includes the number of apnea every hour from the start of the measurement, the average value and the maximum value of the length of the apnea, the low apnea that does not lead to the apnea (change in the respiration temperature signal). Is not zero, but decreases), and analysis data for each body position in the second embodiment described later.

The three operations by the user can be detected, and the space of the operation unit can be reduced and the operability can be improved without impairing the convenience of the user. That is, the key switch 93

Although not shown here, a belt for mounting the apparatus main body 8 is provided on the wrist of the subject, and a belt loop is provided at one end of the belt for fixing the belt through the other end. At the same time, the fixing of the apparatus main body 8 to the wrist is performed by using a magic tape. The apparatus main body 8 is provided with a connector to which the relay cable 10 and the connection cable 11 can be freely connected. Reference numeral 103 denotes a power switch for starting measurement.

The interface unit 9 of the apparatus body 8
The setting to 4 is performed by placing the apparatus main body 8 on the concave portion 95 of the data output interface unit 94 as shown in FIG. In this case, a light emitting element (light emitting diode) 96 disposed on the bottom surface of the device main body 8 and a light receiving element (photodiode) 9 disposed on the concave portion 95 are provided.

The data is transferred to the printer and printed out.

The operation of the above configuration will be described below. FIG. 9 is a flowchart showing a measurement processing procedure of the respiratory function measurement device of FIG. As shown in FIG. 9, before the subject goes to bed, first, in step # 1, the oxygen saturation finger sensor 2 is fixed between the fingertips, and oxygen is applied to the wrist on the side to which the oxygen saturation finger sensor 2 is mounted. After attaching the belt of the saturation finger sensor 2 with a hook-and-loop fastener, the connection cable 11 of the oxygen saturation finger sensor 2 is connected to a predetermined position of the apparatus main body 8 by a connector. In addition, the chest belt 3 to which the relay box 7 is fixed is wrapped around the chest, the microphone 4 is stuck to the throat, the flow sensor 5 is stuck below the nose, and the connection cables 41 and 51 are connected to the predetermined positions of the relay box 7. At the same time, the relay cable 10 of the relay box 7 is connected to the predetermined position of the apparatus main body 8 with the connector.
As described above, the respiratory function measuring device 1 is worn on the body of the subject.

Next, in step # 2, the power switch 103 of the apparatus body 8 is operated to turn on the power, and in step # 3, the measurement of the respiratory function is started.

Further, in step # 4, the arithmetic unit 87
The oxygen saturation and the pulse rate at predetermined time intervals are calculated at predetermined time intervals based on each oxygen saturation signal from the oxygen saturation finger sensor 2.

Further, in step # 5, a calculation result such as oxygen saturation and pulse rate is calculated by the calculation unit 87, and
A respiratory effort signal from the chest belt 3, a tracheal sound / snoring signal from the microphone 4, and a respiratory temperature signal from the flow sensor 5 are sequentially stored in the memory 89 as time measurement data in the memory 89. Thereafter, until the subject wakes up in step # 6 and turns off the power switch 103 of the respiratory function measuring device 1, the arithmetic processing and the storage processing at every predetermined time are continuously performed during the sleeping time of the subject.

The subject returns the respiratory function measuring device 1 to the hospital, and the doctor causes the main body 8 of the respiratory function measuring device 1 to execute an analysis process corresponding to the subject for each memory card 92. The doctor performs a sleep apnea diagnosis using the analysis data.

Here, the analysis processing procedure will be described in detail below. FIG. 10 is a flowchart showing the analysis processing procedure of the respiratory function measuring device of FIG. As shown in FIG. 10, first, in step # 11, a memory card 92 in which an analysis program of the analysis content according to the symptom of the subject is recorded is inserted into the memory card connector 88 of the apparatus main body 8.

Next, when the power is turned on by operating the power switch 103 of the apparatus main body 8 in step # 12, a file to be analyzed is stored in step # 13 (storage contents in the memory 89).
Are sequentially displayed on the display screen 90a by rotating the key switch 93. After the file displayed on the display screen 90a is selected by pressing the key switch 93, the analysis of the selected analysis file is performed in step # 14. Start.

Further, at step # 15, the arithmetic section 87 reads the analysis program from the memory card 92, and the desired analysis operation is executed at step # 16 according to the analysis program. In this case, each measurement data stored in the memory 89 is used as base data for an analysis calculation.
For example, oxygen saturation average value, oxygen saturation minimum value, number of times of oxygen saturation decrease per unit time, pulse rate average value, intensity of respiratory effort every predetermined time, number of stops of respiratory effort, apnea every predetermined time Analysis of analysis data such as the number of tracheal sounds stopped by snoring, the presence or absence of snoring, the number of breaths every predetermined time, the number of breaths stopped every predetermined time, the average number of breaths per unit time, the average number of apnea per unit time Perform the operation.

The data of this analysis result is stored in step # 17.
Is displayed on the display screen 90a, and a plurality of analysis data can be scrolled and displayed on the display screen 90a by operating the key switch 93 provided in the apparatus main body 8 in step # 18.

Further, in step # 19, the data output unit 9
By connecting a printer 98 as shown in FIG. 8 to one output terminal, the analysis data can be printed out by the printer 98. Thereafter, in step # 20, the power switch 103 of the respiratory function measurement device 1 is operated to turn off the power, and the analysis process is terminated.

Also, if the doctor confirms that the analysis data has been printed out and then realizes that there is necessary analysis data, the procedure returns to step # 11 to analyze the necessary analysis contents according to the symptoms of the subject. The memory card 92 on which the program is recorded may be inserted into the memory card connector 88 of the apparatus main body 8, and the above-described steps # 12 to # 20 may be repeated.

As described above, according to the first embodiment, an analysis program for desired data analysis is recorded for each memory card 92, and based on the analysis program read from the memory card 92 by the memory card connector 88. Because we analyzed respiratory data and obtained parameters related to respiratory data, new analysis methods were proposed,
Even when the necessary analysis method differs for each symptom of the subject, it is possible to easily change or add a new analysis method or a desired analysis program to the memory card according to the symptom of the subject.

Further, since the device main body 8 is mounted on the wrist of the subject, the length of the connection cable 11 from the device main body 8 to the oxygen saturation finger sensor 2 is short, so that the connection cable 11 is less likely to wrap around the body. has been connected cable 11 without cumbersome, subject also never such as to come off or deviated finger sensor 2 is pulled by the connecting cable 11 as moved by such rolling over. The connection from the relay box 7 attached to the chest to the apparatus main body 8 attached to the wrist, to which each of the respiratory sensors such as the chest belt 3, the microphone 4 and the flow sensor 5 are connected, is made by a single relay cable 10. Since the number of cables is small and integrated with the body, the cable is less entangled with the body, the cables are not bothersome, and various breathing is performed when the subject moves due to turning over etc. The sensor will not be pulled or dislodged or dislodged.

Further, since the key switch 93 in which the rotation direction operation and the pressing operation are combined is used, the operability is good, and the space for the operation section is reduced, so that the main body can be downsized. In addition, since the display contents of the display screen 90a of the display device 90 are sequentially displayed using the key switch 93, the size of the display screen 90a may be small, and the apparatus body 8 provided with the display screen 90a can be downsized. Becomes

(Embodiment 2) Embodiment 2 is a case where a body position sensor as a biological information sensor is provided in addition to Embodiment 1 described above.

FIG. 11 is a block diagram showing an example of a control configuration different from that of the apparatus main body of FIG. 5. Members having the same functions and effects as those of FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted.
11, the respiratory function measuring device 12 has a position sensor 6 for detecting a position. The position sensor 6 is connected to a device main body 80 via a connection cable 63, a relay box 7, and a relay cable 10 shown in FIG. Posture signal processing unit 8
6 is connected. After the body position detection signal from the body position sensor 6 is subjected to waveform shaping processing by the body position signal processing unit 86, A
The data is input to the calculation unit 87 via the / D conversion unit 81. The arithmetic unit 87 detects the current position in accordance with the input position detection signal and stores the detected position in the memory 89.

The position sensor 6 is provided on a substrate 62 as shown in FIG. As shown in FIG. 13, a connector jack 64 is provided at a distal end of a connection cable 63 connected to each conductive pattern of the board portion 62 and pulled out from the body position sensor unit 61 as shown in FIG. 12. 64 can be connected to a predetermined connector socket of the relay box 7. In the second embodiment, the body position sensor 6 is provided in the body position sensor unit 61. However, the present invention is not limited to this, and the body position sensor 6 may be built in the relay box 7.

The position detection by the position sensor 6 is as follows.
As shown in FIG. 13, the orientation of the body during sleep, that is, the supine position (when sleeping upward), the left reclining position (when sleeping left side down), the right reclining position (right side downward) And sleeping) and standing.
That is, the body position sensor 6 is tilted low, for example, toward the front side, and has a metal sphere (not shown) for short-circuiting the terminal therein, and the terminals 65a, 65a of each conductive pattern according to the position of the metal sphere made of a conductor. Two terminals of 65b, 65c and 65d are connected. For example, when the subject is standing, the terminals 65a, 65b, 65c, 6
In the prone position, all the terminals of 5d are detected such that the open position detection signal is detected. In FIG. 12, the position sensor 6 is tilted so that the near side is downward.
Is short-circuited by a metal sphere and the position detection signal in which the terminals 65a and 65b are open is output. Also, for example, when the subject is in the supine position, the back side of the position sensor 6 in FIG. , 65b are short-circuited by metal spheres and the terminals 65c, 65d are open, a position detection signal is output. For example, when the subject is in the left recumbent position, FIG.
2, the right side toward the body position sensor 6 is downward, so that the terminals 65 b and 65 d are short-circuited by metal spheres, and
a, a position detection signal is output with 65c open, and
For example, when the subject is in the right recumbent position, the left side is facing down toward the body position sensor 6 in FIG.
5c is short-circuited by a metal sphere, and a position detection signal in which the terminals 65b and 65d are open is output.
With the position detection signal, it is possible to detect in what position the subject is sleeping or standing up.

As described above, according to the second embodiment, for example, since a necessary analysis method is different for each symptom of the subject, when it is necessary to make the analysis contents of sleep apnea syndrome more detailed, It can be easily rewritten or added to the analysis program including the detection of the position of the subject.

As described above, since the position of the subject at the time of measurement of the respiratory function or the like is known, the measurement data can be analyzed in more detail. For example, in the case of obstructive apnea syndrome, since the degree of appearance of symptoms varies depending on the position of the subject during sleep, it is preferable to detect the position. For example, when the subject is fat and is in a supine position (when sleeping upward), the trachea may be compressed by the weight of the flesh of the throat, and the trachea passage may be deteriorated. Therefore, in the diagnosis of obstructive apnea syndrome, the determination is basically made based on the presence or absence of respiratory effort, and the body position of the subject is an important parameter.
