Description

The present invention, the biological information measurement device, the operation information acquisition device, and relates to home oxygen therapy management support method, and home oxygen therapy management support program in the biological information measuring device.

Home oxygen therapy (HOT) is a treatment for improving the value of arterial oxygen saturation in a patient. Arterial oxygen saturation (SpO ₂ : hereinafter abbreviated as “oxygen saturation”) is a biological parameter that represents the ratio of oxyhemoglobin to total hemoglobin in arterial blood.

  In home oxygen therapy, an oxygen supply device is used. An oxygen concentrator, which is a type of oxygen supply device, compresses indoor air taken in through a filter and intake tank with a compressor and passes the compressed air through a sheave bed while repeating switching between pressure and pressure, and then high-concentration oxygen from the compressed air. And supply high concentration oxygen to the patient through the nasal cannula.

  The patient installs an oxygen concentrator at home, and inhales high-concentration oxygen from the oxygen concentrator according to a doctor's prescription at home. When going out, the patient uses a portable oxygen cylinder as needed, and inhales high-concentration oxygen from the oxygen cylinder.

  The doctor who decides the prescription of oxygen flow rate etc. for the patient will follow the home oxygen therapy and improve the numerical value of oxygen saturation by reviewing the prescription etc. as appropriate, and eventually the patient's QOL (Quality of Life) ). In order to achieve this, doctors not only examine the patient's condition during follow-up, but also the accuracy of the prescription determined by the patient or the patient's prescription compliance status (hereinafter referred to as “the course of home oxygen therapy”). Confirmation is also required.

  Here, since home oxygen therapy is performed in an environment away from a doctor, means for obtaining a judgment material for performing the confirmation are limited. In general, information that can be used as a judgment material is often acquired by interrogating a patient or reading a diary or the like written by the patient. In addition, data on oxygen saturation measured and recorded by a pulse oximeter (for example, see Patent Document 1) may be used as a judgment material.

  A pulse oximeter is a device for non-invasively measuring a patient's arterial oxygen saturation in daily life. The pulse oximeter acquires a biological signal using light from a predetermined part such as a fingertip, and processes and acquires the arterial blood oxygen saturation by processing the acquired biological signal. In recent years, a small and light pulse oximeter that can be worn on a fingertip has been put into practical use.

  Interviews and diaries are often based on patient subjectivity. On the other hand, since the measurement information obtained by using the pulse oximeter is numerical information, the use of the pulse oximeter is advantageous in that objective information is obtained. Moreover, among medical professionals, daily use of pulse oximeters is widely considered effective for patient self-management.

Japanese Patent Application Laid-Open No. 7-1000012

  However, there is no clear evidence on how to evaluate and continue self-management based on the obtained measurement information.

  In addition, the value of oxygen saturation spot-measured by a pulse oximeter has a large individual difference between the average value and normal value depending on the degree and type of disease. It is not easy to check the course of therapy correctly.

  Therefore, it is conceivable to use log data of the instrument operation of the oxygen concentrator. That is, when confirming the progress of home oxygen therapy, measurement information that can be acquired from the pulse oximeter and operation information (set flow rate, operation time, etc.) of the oxygen concentrator that can be acquired from the oxygen concentrator. It is possible to use it together.

  However, the operation information of the oxygen concentrator and the measured value of the pulse oximeter are generally managed separately as different information. For this reason, these are centrally managed and prescriptions for home oxygen therapy are used. There have not been many proposals for use in confirming accuracy.

  In many cases, a trend graph based on continuous measurement results of a pulse oximeter is used for diagnosis of hypoxemia. However, this trend graph generally shows continuous measurement results for 24 hours, and is therefore not necessarily suitable for applications that evaluate changes in measured values over a period of several weeks, months, or longer. I can't say.

An object of the present invention, it is possible to perform observation of home oxygen therapy more accurately, the biological information measurement device, the operation information acquisition device, and home oxygen therapy management support method in a biological information measurement device and a home oxygen therapy management support program Is to provide

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

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration of a home oxygen therapy management system according to Embodiment 1 of the present invention. A home oxygen therapy management system 100 shown in FIG. 1 is generally installed at a patient's home and used by the patient, a pulse oximeter (biological information measuring device) 120 carried by the patient, The home oxygen therapy management apparatus 130, the display apparatus 140, and the printer apparatus 150 which are usually installed in a medical facility and used by a doctor are included.

  The home oxygen therapy management system 100 is a system comprising a combination of the oxygen concentrator 110, the pulse oximeter 120, the home oxygen therapy management device 130 and the display device 140 or the printer device 150. Therefore, in FIG. Is shown connected to the. However, in particular, the connection between the oxygen concentrator 110 and the pulse oximeter 120 and the connection between the pulse oximeter 120 and the home oxygen therapy management device 130 do not mean a connection that allows continuous communication. This means that the devices are connected so that they can communicate with each other only when data exchange between these devices is necessary.

  In addition, when the structure which can transmit / receive the data acquired by these apparatuses mutually using a removable medium is taken, the structure which connects these apparatuses so that communication is possible is not necessarily required.

  The oxygen concentrator 110 includes an oxygen supply control unit 111, an instrument operation log acquisition unit 112, a clock / calendar function unit 113, and a data transfer processing unit 114. In addition, as described above, the oxygen concentrator 110 compresses the air taken from the room, generates high-concentration oxygen from the compressed air, and supplies the high-concentration oxygen into the patient body via the nasal cannula ( (This is similar to a conventional oxygen concentrator, and detailed description thereof is omitted for the sake of brevity.)

  The oxygen supply control unit 111 controls the supply of high-concentration oxygen from the oxygen concentrator 110 to the patient by an operator (usually the patient himself / herself but may be the patient's family). Control is performed according to an oxygen flow rate value (hereinafter referred to as “set flow rate value”) set by operating a unit (not shown). Normally, the operator sets the oxygen flow rate value according to a prescription flow rate value determined in advance by a doctor (for example, 1.00 L / min at rest, 2.00 L / min at work, 1.50 L / min at bedtime, etc.). Set. However, it is functionally possible to set a non-prescription oxygen flow rate value by the operator's operation and control the supply of high-concentration oxygen according to the set flow rate value.

  Further, the oxygen supply control unit 111 detects a flow value of high-concentration oxygen actually sent from the oxygen concentrator 110 under the control of the set flow value by a flow sensor (not shown). Hereinafter, the detected flow rate value is referred to as “measured flow rate value”.

  The instrument operation log acquisition unit 112 acquires all the operations and events occurring in the oxygen concentrator 110 as instrument operation logs in association with the generation dates and times, and stores the acquired instrument operation logs in an internal storage device (not shown). Store. For example, when a failure or abnormality occurs in the oxygen concentrator 110, the event and the date and time of occurrence thereof are recorded as alarm information, and the period during which the oxygen concentrator 110 is turned on includes the date and time. The set flow rate value set at the time is recorded as operation information. Note that the actual flow rate value detected at each time point may be recorded in addition to the set flow rate value while the oxygen concentrator 110 is powered on.

  The instrument operation log acquisition unit 112 acquires information about the date and time from the clock / calendar function unit 113.

  In addition, “hour” of “date and time” is time, and “day” is date, but the date includes the day of the week in addition to the date. A “day” in a “measurement date” described later is also a date, which means that the day of the week is included in addition to the year, month, and day.

  The data transfer processing unit 114 has a connector (not shown) for connecting the oxygen concentrator 110 and the pulse oximeter 120 so that they can communicate with each other. When the pulse oximeter 120 is connected to the oxygen concentrator 110 via this connector, the data transfer processing unit 114 transmits at least part of the instrument operation log stored in the instrument operation log acquisition unit 112, particularly oxygen The operation information of the concentrator 110 is transferred to the pulse oximeter 120.

  The pulse oximeter 120 includes an oxygen saturation measurement unit 121 (measurement unit) having an oxygen saturation sensor (not shown) and an oxygen saturation measurement circuit (not shown), a data integration unit 122 (measurement information generation unit, Motion information acquisition means), a clock / calendar function section 123, a data transfer processing section 124 (transmission means), and a data storage section 125. The oxygen saturation measuring unit 121 emits red light or infrared light with an oxygen saturation sensor and transmits the red light or infrared light to a specific part of the patient (for example, fingertip, toe, etc.) and detects the transmitted light. Get a signal. Then, the oxygen saturation measuring unit 121 uses the oxygen saturation measurement circuit to obtain the ratio of oxyhemoglobin to the total hemoglobin of arterial blood using the detection signal, and detects a change in absorbance synchronized with the pulse of arterial blood. Thus, the oxygen saturation and the pulse rate (that is, the pulse wave measurement value) are measured. Furthermore, the oxygen saturation measuring unit 121 acquires the oxygen saturation measurement value and the pulse measurement value by converting the measurement result into digital data.

  The data integration unit 122 acquires the oxygen saturation measurement value and the pulse measurement value acquired by the oxygen saturation measurement unit 121 from the oxygen saturation measurement unit 121, and associates the acquired measurement information with the measurement date and time to measure the pulse oximeter. The measurement information 120 is stored in a data storage unit 125 described later. The data integration unit 122 acquires information about the date and time from the clock / calendar function unit 123.

  In addition, the data integration unit 122 acquires the operation information of the oxygen concentrator 110 received from the oxygen concentrator 110 by the data transfer processing unit 124. And the data integration part 122 produces | generates the integrated information which can manage the information about home oxygen therapy centrally by integrating the acquired operation information with the measurement information already stored in the data storage part 125 Then, the generated integrated information is stored in the data storage unit 125.

  The data transfer processing unit 124 includes a connector (not shown) for connecting the pulse oximeter 120 and the oxygen concentrator 110 so that they can communicate with each other. Then, when the pulse oximeter 120 is communicably connected to the oxygen concentrator 110 via this connector, the data transfer processing unit 124 displays at least a part of the instrument operation log, particularly the operation information of the oxygen concentrator 110. , Received from the oxygen concentrator 110.

  Further, the data transfer processing unit 124 transfers the integrated information stored in the data storage unit 125 to the home oxygen therapy management device 130 when the pulse oximeter 120 is connected to the home oxygen therapy management device 130.

  The data storage unit 125 holds the operation information and the integrated information stored by the data integration unit 122. In this embodiment, the data storage unit 125 is built in the pulse oximeter 120, but may be a removable storage medium such as a removable medium.

  The home oxygen therapy management device 130 is typically a device realized by a personal computer, and includes a data transfer processing unit 131, a storage unit 132, and a data analysis unit 133.

  The data transfer processing unit 131 has a connector (not shown) for connecting the pulse oximeter 120 and the home oxygen therapy management device 130 so that they can communicate with each other. Then, when the pulse oximeter 120 is connected to the home oxygen therapy management device 130 via this connector, the data transfer processing unit 131 receives the integrated information from the pulse oximeter 120. The received integrated information is stored in the storage unit 132.

  When the pulse oximeter 120 is configured to store integrated information in a removable medium, the data transfer processing unit 131 has a connector for connecting the removable medium, and the removable device connected to this connector. The integrated information stored in the medium is read, and the read integrated information is stored in the storage unit 132.

  In addition to the integrated information, the storage unit 132 includes patient information (for example, basic patient information, vital information, prescription flow rate information, and the like) that is input by a doctor or other medical staff operating an input unit (not shown). Is stored). Further, the storage unit 132 stores a home oxygen therapy management program for analyzing home oxygen therapy based on the integrated information.

  The data analysis unit 133 serving as an acquisition unit and a generation unit includes a calculation device (not shown) such as a CPU (Central Processing Unit), and the storage unit 132 by executing a home oxygen therapy management program using the calculation device. An acquisition function for acquiring integrated information stored in the computer, analysis of home oxygen therapy based on the acquired integrated information, and display of analysis information as a result of the analysis on the screen of the display device 140 (for example, a liquid crystal display) Or a creation function for creating analysis information by causing the printer device 150 (for example, a laser printer) to print on paper.

  FIG. 2 is a flowchart for explaining the analysis information creation operation of the data analysis unit 133. When a medical worker operates an input unit (not shown) of the home oxygen therapy management device 130 to input an analysis information creation instruction to the data analysis unit 133, the data analysis unit 133 From the integrated information stored in the storage unit 132, the oxygen saturation measurement value, the pulse measurement value, the measurement date and time, the information about the set flow rate value of the oxygen concentrator 110 and the operation date and time are obtained by the acquisition function. Extract (step S100). Based on the extracted information, the data analysis unit 133 displays or prints the analysis information of the oxygen saturation measurement value and the pulse measurement value as analysis information of home oxygen therapy based on the extracted information (step S200).

  Hereinafter, analysis information created by the data analysis unit 133 will be described with reference to examples shown in FIGS. Here, a case where analysis information is displayed on the screen of the display device 140 will be described as an example. However, as described above, analysis information can also be created on a sheet by printing.

  FIG. 3 is a diagram illustrating an example of a distribution diagram of oxygen saturation measurement values for each pulse measurement value.

  When a medical worker performs identification information input to the identification information (ID) input field 142a in the window 141 and clicks the display button 142b while the oxygen operation status viewer window 141 is displayed on the screen. Then, an analysis information display instruction is input as an analysis information creation instruction to the data analysis unit 133, and the data analysis unit 133 displays the analysis information on the analysis information display unit 142c accordingly. When a click operation of the print button 142d is performed instead of the display button 142b, an analysis information print instruction is input to the data analysis unit 133 as an analysis information creation instruction, and the data analysis unit 133 analyzes the printer device 150. Print information.

  The analysis information to be displayed can be selected by an operation. In this example, the distribution map 143a of oxygen saturation measurement values for each pulse measurement value is displayed on the analysis information display unit 142c.

  In addition, patient information is displayed on the patient information display unit 142e. The patient information display unit 142e is a basic patient information display unit 142f that displays personal basic information such as a patient's name, a vital information display unit 142g that displays vital information such as a patient's height, and a prescription that displays prescription flow rate information of the patient. It has a flow rate information display part 142h. The patient information can be input using the patient information display unit 142e.

  The distribution map 143a is created based on the portion corresponding to the period (for example, one month) specified by the operation in the integrated information stored in the storage unit 132. That is, for example, when a period from July 24 to August 23 is designated, the result of the spot measurement performed during that period is displayed. In the case of the distribution diagram 143a of the oxygen saturation measurement value by pulse measurement value, the measurement value in each spot measurement is shown on a plane having the X axis as the pulse measurement value axis and the Y axis as the oxygen saturation measurement value axis. Marks 144a-144e are plotted.

  Each mark 144a-144e shows the pulse measurement value and oxygen saturation measurement value which were obtained in the spot measurement performed at a certain date and time. Accordingly, the different marks 144a to 144e indicate the pulse and oxygen saturation measured at different dates or times.

  The marks 144a to 144e are shown in a manner of visualizing the set flow rate value of the oxygen concentrator 110 at the measurement date and time of the pulse measurement value and the oxygen saturation measurement value indicated by the respective marks 144a to 144e.

  More specifically, the mark 144a indicating the oxygen saturation and the pulse measured when the set flow rate value is set to 1.00 L / min is indicated by a square (□ mark). In the illustrated example, the mark 144a is not shown in such a manner that the set flow rate value itself can be directly discriminated, but the prescription flow rate for resting at the time when the oxygen saturation and the pulse are measured. It is shown in such a manner that it can be directly discriminated that the value has been applied. In other words, it can be determined that the oxygen saturation measurement value and the pulse measurement value are measured when the oxygen flow rate value is set according to the prescription flow rate value for resting. In the illustrated example, referring to the prescription flow rate information display unit 142h, the prescription flow rate value for resting is 1.00 L / min. Therefore, it can be determined that the set flow rate value at the measurement date is 1.00 L / min. .

  Further, the mark 144b indicating the oxygen saturation and the pulse measured when the set flow rate value is set to 2.00 L / min is indicated by a round shape (◯ mark). In the illustrated example, the mark 144b is not shown in such a manner that the set flow rate value itself can be directly discriminated, but the prescription flow rate for working at the time when the oxygen saturation and the pulse are measured. It is shown in such a manner that it can be directly discriminated that the value has been applied. In other words, it can be determined that the oxygen saturation measurement value and the pulse measurement value are measured when the oxygen flow rate value is set according to the prescription flow value for working. In the illustrated example, referring to the prescription flow rate information display unit 142h, the prescription flow rate value for work is 2.00 L / min. Therefore, it can be determined that the set flow rate value at the measurement date is 2.00 L / min. .

  Further, a mark 144c indicating the oxygen saturation and the pulse measured when the set flow rate value is set to 1.50 L / min is indicated by a rhombus (（mark). In the illustrated example, the mark 144c is not shown in such a manner that the set flow rate value itself can be directly discriminated, but the prescription flow rate for sleeping at the time when the oxygen saturation and the pulse are measured. It is shown in such a manner that it can be directly discriminated that the value has been applied. In other words, it can be determined that the oxygen saturation measurement value and the pulse measurement value are measured when the oxygen flow rate value is set according to the prescription flow rate value for sleeping. In the illustrated example, referring to the prescription flow rate information display unit 142h, the prescription flow rate value for bedtime is 1.50 L / min. Therefore, it can be determined that the set flow rate value at the measurement date is 1.50 L / min. .

  A mark 144d indicating the oxygen saturation and the pulse measured when the set flow rate value is set to 3.00 L / min or 4.00 L / min is indicated by a triangle (Δ mark). In the illustrated example, the mark 144d is not shown in such a manner that the set flow rate value itself can be directly discriminated, and the power source of the oxygen concentrator 110 is measured at the time when the oxygen saturation and the pulse are measured. Is supplied and high-concentration oxygen is being supplied, but it is shown in such a manner that it can be directly determined that none of the predetermined prescription flow rate values are applied. In other words, it can be determined that the oxygen flow rate measurement value and the pulse measurement value are measured when an oxygen flow rate value different from the prescription flow rate value is set. In the illustrated example, referring to the prescription flow rate information display unit 142h and the flow rate value selection column 145a that can be selected, the flow rate values outside the prescription are 3.00 L / min and 4.00 L / min. It can be determined that the set flow rate value at is 3.00 L / min or 4.00 L / min.

  A mark 144e indicating the oxygen saturation and pulse measured when high-concentration oxygen is not supplied (that is, when the flow rate value is 0.00 L / min) is indicated by a cross (+). Has been. In the illustrated example, the mark 144e is not shown in such a manner that the oxygen flow rate value itself can be directly discriminated, and the power source of the oxygen concentrator 110 is measured at the time when the oxygen saturation and the pulse are measured. Is shown in such a manner that it can be directly discriminated that no is inserted. In other words, if the power is not turned on, the oxygen concentrator 110 does not supply high-concentration oxygen, so that it can be determined that the oxygen flow rate value at the measurement date is 0.00 L / min.

  Here, the measurement date and time is the date and time indicated by the timepiece / calendar function unit 123 at the time when the oxygen saturation measurement unit 121 measures the oxygen saturation and the pulse in the pulse oximeter 120. However, if necessary (for example, when the difference from the standard time is large), the data analysis unit 133 sets a value obtained by correcting the date and time indicated by the clock / calendar function unit 123 at the time of measurement. It can also be a measurement date. Here, there may be a difference in the date and time (particularly the time) shown between the clock / calendar function unit 123 of the pulse oximeter 120 and the clock / calendar function unit 113 of the oxygen concentrator 110. In this case, it is desirable that the data integration unit 122 of the pulse oximeter 120 performs a process of including the difference itself in the integrated information.

  Specifically, for example, the data integration unit 122 includes information indicating the date and time (hereinafter referred to as “time information” as appropriate) included in the operation information by the oxygen concentrator 110 and the pulse oximeter 120 at the time when the operation information is received. Are associated with the time information indicated by the clock / calendar function unit 123 in the integrated information. Alternatively, the data integration unit 122 detects a difference between the time information included in the operation information by the oxygen concentrator 110 and the time information indicated by the clock / calendar function unit 123 of the pulse oximeter 120 at the time when the operation information is received. The detected difference is included in the integrated information. As a result, even if there is a difference in the clock / calendar function between the pulse oximeter 120 and the oxygen concentrator 110, the data analysis unit 133 corrects the difference, and the pulse measurement value and the oxygen saturation measurement value It is possible to accurately display the set flow rate value at the actual date and time when is measured.

  In the illustrated example, by plotting the marks 144a to 144e in different shapes for each oxygen flow rate value, the difference in oxygen flow rate value can be made obvious at a glance. However, if color display is possible, the marks 144a to 144e may be plotted in different colors for each oxygen flow rate value. Other display modes are also possible, and the display modes of the marks 144a to 144e can be changed as needed.

  In addition, by performing a selection operation in the prescription selection field 145b, a mark 144a indicating a measured value at the time of application of the oxygen flow rate value determined as a prescription flow value for rest, and determined as a prescription flow value for work A mark 144b indicating a measurement value at the time of application of the oxygen flow value, a mark 144c indicating a measurement value at the time of application of the oxygen flow value determined as a prescription flow value for sleeping, and a measurement at the time of application of an oxygen flow value outside the prescription It is also possible to selectively plot the mark 144d indicating the value or the mark 144e indicating the measured value when the power is turned off.

  In this way, by creating the distribution diagram 143a of the oxygen saturation measurement value for each pulse measurement value as shown in FIG. 3, the tendency of the oxygen saturation measurement value with respect to the pulse measurement value is supplied from the oxygen concentrator 110. It can be grasped in relation to the oxygen flow rate value. For example, not only can you see the tendency of the oxygen saturation measurement to decrease as the pulse measurement rises, but the oxygen saturation measurement for work is compared to the oxygen saturation measurement for rest It can also be seen that there is a tendency to decrease. Therefore, it is possible to consider reconsideration of prescriptions for exertion. Further, for example, it can be understood that the pulse measurement values when the power is turned off are dispersed in the oxygen saturation measurement values when the power is turned off. Therefore, since it is possible to recognize the possibility that the patient has gone out without carrying an oxygen cylinder, an inquiry about the possibility can be made.

  FIG. 4 is a diagram illustrating an example of a distribution diagram of oxygen saturation measurement values by measurement time.

  The distribution diagram 143b of the oxygen saturation measurement value by measurement time is based on the portion corresponding to the period specified by the operation in the integrated information stored in the storage unit 132, and the spot performed during that period. Created to display the result of the measurement. In the case of the distribution diagram 143b of the oxygen saturation measurement value by measurement time, the marks 144a to 144d indicate the measurement values in each spot measurement on a plane having the X axis as the time axis and the Y axis as the oxygen saturation measurement value axis. 144e is plotted.

  In addition, this distribution map 143b is different from the display of the measurement values in time series as in the trend graph, for example, even if the measurement dates of the plurality of oxygen saturation measurement values are different, the measurement time is the same. The X coordinates of a plurality of marks indicating them are the same. Therefore, it is possible to grasp the tendency of the overall measurement value in the daily life over a long period, not the tendency of the measurement value in a specific day.

  In this way, by creating the distribution diagram 143b of the oxygen saturation measurement value for each measurement time as shown in FIG. 4, the tendency of the oxygen saturation measurement value with respect to the measurement time is represented by the oxygen supplied from the oxygen concentrator 110. It can be grasped in relation to the flow rate value. For example, not only can you understand that the oxygen saturation is stable at high values in the morning and at night, but the oxygen saturation tends to decrease slightly in the daytime. It is possible to grasp that there is a tendency to decrease slightly regardless of the measurement time zone, and to review the prescription for working time. Further, for example, it can be understood that the oxygen concentrator 110 is not used much around 15:00. Therefore, the possibility that the patient is out on a daily basis during that time period can be recognized without depending on a diary or an inquiry.

  FIG. 5 is a diagram illustrating an example of a transition diagram of resting pulse measurement values.

  The transition diagram 143c of the pulse measurement value at rest is a part of the integrated information stored in the storage unit 132 corresponding to the period specified by the operation (in the past three months in this example) and the subsequent one month. Based on the result, the result of the spot measurement performed during the period is displayed. In the case of FIG. 143c, the measured pulse rate for resting (prescription flow rate value of 1.00 L / min in this example) is 143c. The X-axis is the axis of the number of days from the measurement date to the analysis date, and the Y-axis is A mark 144f indicating the pulse measurement value in each spot measurement is plotted on the plane.

  In addition, a line 145 indicating the average value of the pulse measurement values in the designated past three months is displayed, and 120% of the average value of the pulse measurement values in the designated past three months is used as a reference for comparison. A line 146 indicating a value corresponding to is displayed. Thereby, the tendency of the pulse measurement value with respect to the same prescription flow value can be grasped.

  FIG. 6 is a diagram showing an example of an average value comparison chart of oxygen saturation measurement values by time period.

  The average value comparison diagram 143d of the oxygen saturation measurement values by time zone is performed during the period based on the portion corresponding to the period specified by the operation in the integrated information stored in the storage unit 132. It is created to display the result of spot measurement. In the case of FIG. 143d, the oxygen saturation measurement values by time zone are compared with each other on the plane having the X axis as the time zone axis and the Y axis as the oxygen saturation measurement value and measurement frequency axis. The average value of the saturation measurement values is displayed by a line graph, and the number of measurements for each time zone is displayed by a bar graph. The average value and the number of times for each time zone are calculated by the data analysis unit 133. The average value comparison chart 143d makes it possible to make the tendency of each time zone clear at a glance, and to simultaneously grasp the reliability of each average value. For example, it can be seen that the reliability of the average value of oxygen saturation measured in the daytime is relatively high because the number of measurements is relatively large in the daytime when the average value tends to decrease. On the other hand, since the number of measurements is relatively small at bedtime, it can be seen that the reliability is not necessarily high even if the average value is good.

  FIG. 7 is a diagram illustrating an example of an average value comparison chart of oxygen saturation measurement values for each oxygen flow rate value.

  The average value comparison chart 143e of the oxygen saturation measurement values for each oxygen flow rate value is based on the portion corresponding to the period specified by the operation in the integrated information stored in the storage unit 132. It is created so that the result of the measured spot measurement is displayed. In the case of the average value comparison diagram 143e of the oxygen saturation measurement value by oxygen flow rate value, the oxygen flow rate value on a plane having the X axis as the axis of the oxygen flow rate value and the Y axis as the axis of the oxygen saturation measurement value and the number of measurements. The average value of the oxygen saturation measurement values for each is displayed by a line graph, and the number of measurements for each oxygen flow rate value is displayed by a bar graph. Note that the average value and the number of times for each oxygen flow rate value are calculated by the data analysis unit 133. The average value comparison chart 143d makes it possible to clearly see the tendency for each oxygen flow rate value and to simultaneously grasp the reliability of each average value.

  FIG. 8 is a diagram showing an example of an average value comparison chart of oxygen saturation measurement values by day of the week.

  The average value comparison diagram 143f of the oxygen saturation measurement values by day of the week was performed during the period based on the portion corresponding to the period specified by the operation in the integrated information stored in the storage unit 132. It is created so that the result of the spot measurement is displayed. In the case of the average value comparison diagram 143f of the oxygen saturation measurement values for each day of the week, a line graph is displayed on a plane having the X axis as the day of the week axis and the Y axis as the oxygen saturation measurement value and pulse measurement value axes. Specifically, a line graph of the average value of the oxygen saturation measurement values for each day of the week is displayed for each measurement time zone, and the average value of the pulse measurement values for each day of the week is also displayed for each measurement time zone. The average value for each day of the week and each time zone is calculated by the data analysis unit 133. With this average value comparison chart 143f, the tendency for each day of the week can be made clear at a glance. For example, it can be seen that on Saturdays, the oxygen saturation tends to decrease and the pulse tends to increase. In addition, the line graph of the average value of a specific time slot | zone can also be selectively displayed by selection operation.

  As described above, according to the present embodiment, as the analysis information of the oxygen saturation measurement value and the pulse measurement value, the mark indicating the arterial oxygen saturation measurement value is the oxygen flow rate at the measurement date and time of the arterial oxygen saturation measurement value. A distribution chart in which values are discriminated is created. For this reason, the correlation between the distribution tendency of the oxygen saturation measurement value and the set flow rate value can be easily and clearly found, and the accuracy of the prescription can be accurately determined. It is also possible to obtain objective judgment material as to whether the patient is complying with the prescription from the distribution of measured oxygen saturation values. That is, detailed follow-up of home oxygen therapy can be performed by effectively utilizing the spot measurement result of the pulse oximeter 120. Furthermore, it is possible to grasp a more detailed home care life without depending on a subjective and limited amount of information from the patient, and contribute to improvement of the patient's QOL.

(Embodiment 2)
FIG. 9 is a block diagram showing a configuration of the home oxygen therapy management system according to the second embodiment of the present invention, and corresponds to FIG. 1 of the first embodiment. The same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

  As shown in FIG. 9, the home oxygen therapy management system 100a according to the present embodiment includes an oxygen concentrator 110a including an instrument operation log acquisition unit 112a that performs an operation different from that of the first embodiment, and the first embodiment. And a pulse oximeter 120a provided with a data integration unit 122a (measurement information generation means, measurement time system setting means) that performs different operations. The home oxygen therapy management system 100a according to the present embodiment includes a cradle (operation information acquisition device) 160a. In the present embodiment, the pulse oximeter 120a acquires the operation information of the oxygen concentrator 110a not from the oxygen concentrator 110a but from the cradle 160a. In the present embodiment, it is assumed that at least pulse oximeter 120a is capable of manual clock adjustment and clock adjustment from home oxygen therapy management device 130 after factory shipment.

  The instrument operation log acquisition unit 112a of the oxygen concentrator 110a transmits the acquired instrument operation log as event information to the cradle 160a via the data transfer processing unit 114 every time the instrument operation log is acquired. The event information includes, for example, alarm information such as the occurrence of a failure or abnormality, switching of a set flow rate value, starting and stopping of oxygen supply, and an actual flow rate value during oxygen supply. The event information does not necessarily include time information (hereinafter referred to as “concentrator time”) based on the time system (hereinafter referred to as “concentrator time system”) of the internal clock (clock / calendar function unit 113) of the oxygen concentrator 110a. Also good.

  The cradle 160a is an extension device of the pulse oximeter 120a, is fixed to the outer surface of the oxygen concentrator 110a, and is configured to be detachable from the pulse oximeter 120a. When the pulse oximeter 120a is mounted, the cradle 160a charges the pulse oximeter 120a using the power supply of the oxygen concentrator 110a.

  The cradle 160a receives event information from the oxygen concentrator 110a, and the received operation information includes time information (hereinafter referred to as “cradle time system”) based on the time system of the internal clock of the cradle 160a (hereinafter referred to as “cradle time system”). Information related to “cradle time”) is stored as operation information. The time from when the oxygen concentrator 110a operates until the cradle 160a receives event information is short. Therefore, the operation information of the present embodiment is the same as the operation information of the first embodiment except that the cradle time system is used as a reference instead of the concentrator time system.

  Further, the cradle 160a is connected to the pulse oximeter 120a, and the cradle time and the time system (measurement time system, hereinafter referred to as “oximeter time system”) of the internal clock (clock / calendar function unit 123) of the pulse oximeter 120a. ) With the clock.

  The cradle 160a includes a data management unit 162a (operation time system setting unit, detection unit, operation information generation unit), a clock / calendar function unit 163a, a data transfer processing unit 164a, and a data storage unit 165a.

  The data management unit 162a acquires the event information of the oxygen concentrator 110a received by the data transfer processing unit 164a from the oxygen concentrator 110a. Then, the data management unit 162a stores information obtained by associating the acquired event information with the cradle time acquired from the clock / calendar function unit 163a in the data storage unit 165a as operation information of the oxygen concentrator 110a.

  In addition, when the data management unit 162a is communicably connected to the pulse oximeter 120a via the data transfer processing unit 164a, the data management unit 162a is connected to the pulse oximeter 120a with a clock of an oximeter time system and a cradle time system. Align. More specifically, when the reliability of the oximeter time system is high, the data management unit 162a adjusts the clock / calendar function unit 163a to adjust the cradle time system to the oximeter time system.

  The data transfer processing unit 164a includes a connector (not shown) for connecting the cradle 160a, the oxygen concentrator 110a, and the pulse oximeter 120a so that they can communicate with each other. The data transfer processing unit 164a receives the event information sent from the oxygen concentrator 110a while being communicably connected to the oxygen concentrator 110a via this connector, and the received event information is converted into the data It passes to the management unit 162a.

  Further, the data transfer processing unit 164a transfers the operation information stored in the data storage unit 165a to the pulse oximeter 120a when connected to the pulse oximeter 120a via a connector so as to be communicable.

  The data storage unit 165a holds the operation information stored by the data management unit 162a. In this embodiment, the data storage unit 165a is built in the cradle 160a, but may be a removable storage medium such as a removable medium.

  As in the first embodiment, the data integration unit 122a of the pulse oximeter 120a integrates the measurement information in which the oxygen saturation measurement value and the pulse measurement value are associated with the oximeter time, and the operation information of the oxygen concentrator 110a. The integrated information is stored in the data storage unit 125.

  In addition, when the data integration unit 122a is communicably connected to the cradle 160a via the data transfer processing unit 124, the data integration unit 122a performs time adjustment of the cradle time system and the oximeter time system with the cradle 160a. More specifically, when the reliability of the oximeter time system is low, the data integration unit 122a adjusts the timepiece / calendar function unit 123 to adjust the oximeter time system to the cradle time system.

  Note that the data management unit 162a of the cradle 160a and the data integration unit 122a of the pulse oximeter 120a each have an arithmetic device (not shown) such as a CPU, for example, and perform functions by executing a program by the arithmetic device.

  The home oxygen therapy management system 100a having such a configuration can generate integrated information obtained by integrating the operation information of the oxygen concentrator 110a and the measurement information of the pulse oximeter 120a during charging of the pulse oximeter 120a. . In other words, the home oxygen therapy management system 100a can generate and transport the integrated information without making the patient aware of it and without particularly burdening it. Moreover, since the home oxygen therapy management system 100a performs the clock adjustment of the cradle time system and the oximeter time system, it is possible to generate integrated information with high accuracy.

  The reliability of the oximeter time system or the cradle time system decreases when a long time elapses from the clock setting or when the internal clock is initialized. It is easier for the pulse oximeter 120a carried by the patient to detect time system deviation and to adjust the clock than the cradle 160a fixed to the oxygen concentrator 110a installed at the patient's home. Therefore, normally, the accuracy of the oximeter time system is higher than the accuracy of the cradle time system, and the time adjustment should be performed based on the oximeter time system.

  However, the accuracy of the oximeter time system may be lower than the accuracy of the cradle time system when the patient performs the clock adjustment operation or when the internal clock is initialized and left as it is. is there. In such a case, the time should be set with reference to the cradle time system.

  Therefore, the home oxygen therapy management system 100a according to the present embodiment uses the oximeter time system as a reference when the reliability of the oximeter time system is high, and uses the cradle time system as a reference when the reliability of the oximeter time system is low. , Set the clock. Thereby, the home oxygen therapy management system 100a can generate integrated information with high reliability of time information. Therefore, for example, a doctor can use integrated information with higher accuracy when performing follow-up of a patient's home oxygen therapy using integrated information as in the first embodiment. Can be performed more accurately.

  Next, operations of pulse oximeter 120a and cradle 160a according to the present embodiment will be described.

  FIG. 10 is a flowchart for explaining the operation of the pulse oximeter 120a. Here, the description will be given focusing only on the operation relating to the integrated information. The pulse oximeter 120a uses the first flag and the second flag as flags indicating the reliability of the oximeter time system. The first flag indicates that time adjustment is performed when the value is 0 (regardless of whether the reliability is high or low), and indicates that time adjustment is not performed when the value is 1. When the value is 0, the second flag indicates that the reliability of the oximeter time system is low, and when the value is 1, the reliability of the oximeter time system is high.

  First, in steps S1010 to S1030, the data integration unit 122a sequentially determines whether the clock has been manually set, whether the home oxygen therapy management device 130 has set the clock, and whether the internal clock has been initialized. to decide. The internal clock is initialized when, for example, a protection circuit (not shown) of the pulse oximeter 120a is activated for some reason. Note that the data integration unit 122a may treat the case where the internal clock is in the initial state as the state where the internal clock is initialized.

  If the clock is manually set (S1010: YES), the data integration unit 122a proceeds to step S1070 via step S1040, and if the clock is set from the home oxygen therapy management device 130 (S1020). : YES), the process proceeds to step S1070 via step S1050. In addition, when the clock is initialized (S1030: YES), the data integration unit 122a proceeds to step S1070 through step S1060, and when neither the clock adjustment nor the clock initialization is performed ( S1010: NO, S1020: NO, S1030: NO), the process proceeds to step S1070.

  In step S1040, the data integration unit 122a sets the first flag to 0 and sets the second flag to 0.

  In step S1050, the data integration unit 122a sets the first flag to 0 and sets the second flag to 1.

  In step S1060, the data integration unit 122a sets the first flag to 1 and sets the second flag to 1.

  In step S1070, the data integration unit 122a determines whether or not the first flag is 0. The data integration unit 122a proceeds to step S1080 when the first flag is 0 (S1070: YES), and proceeds to step S1090 when the first flag is 1 (S1070: NO).

  In step S1080, the data integration unit 122a generates measurement information in which the oximeter time by the clock / calendar function unit 123 is associated with the measurement value by the oxygen saturation measurement unit 121, and the generated measurement information is stored in the data storage unit 125. To store.

  In step S1100, the data integration unit 122a determines whether or not the pulse oximeter 120a is newly attached to the cradle 160a. If the pulse oximeter 120a is newly attached to the cradle 160a (S1100: YES), the data integration unit 122a proceeds to step S1110. Further, when the pulse oximeter 120a is not newly attached to the cradle 160a or the state where the pulse oximeter 120a is attached to the cradle 160a continues (S1100: NO), the data integration unit 122a proceeds to step S1130.

  In step S1110, the data integration unit 122a transmits the value of the first flag and the value of the second flag to the cradle 160a and exchanges the current time with the cradle 160a. That is, the data integration unit 122a transmits the current time based on the oximeter time system to the cradle 160a together with the flag value indicating the reliability, and receives the current time based on the cradle time system from the cradle 160a.

  In step S1120, the data integration unit 122a next determines whether the second flag is 0 or not. If the second flag is 0 (S1120: YES), the data integration unit 122a proceeds to step S1150 through step S1140. If the second flag is 1 (S1120: NO), the data integration unit 122a directly performs step S1150. Proceed to

  In step S1140, the data integration unit 122a adjusts the oximeter time system to the cradle time system. More specifically, the data integration unit 122a adjusts the clock / calendar function unit 123 so that the transmitted current time matches the current time received from the cradle 160a.

  In step S1150, when the operation information of the oxygen concentrator 110a is sent from the cradle 160a, the data integration unit 122a receives the operation information and stores the received operation information in the data storage unit 125. As described above, this operation information is integrated with measurement information to form integrated information.

  In step S1160, the data integration unit 122a determines whether to continue the process related to the integrated information. The data integration unit 122a returns to step S1010 when continuing the process regarding the integrated information (S1160: YES), and ends the series of processes when not continuing the process regarding the integrated information (S1160: NO). To do.

  On the other hand, in step S1130, the data integration unit 122a determines whether or not the pulse oximeter 120a is newly connected to the home oxygen therapy management device 130. If the pulse oximeter 120a is newly connected to the home oxygen therapy management device 130 (S1130: YES), the data integration unit 122a proceeds to step S1170. In addition, the data integration unit 122a, when the pulse oximeter 120a is not newly connected to the home oxygen therapy management device 130, or continues to be connected to the home oxygen therapy management device 130 (S1130: NO), the process proceeds to step S1160.

  In step S <b> 1170, the data integration unit 122 a determines whether the data storage unit 125 stores integrated information that has not been transmitted to the home oxygen therapy management device 130. When unsent integrated information is stored (S1170: YES), the data integration unit 122a proceeds to step S1180, and when unsent integrated information is not stored (S1170: NO). The process proceeds to step S1160.

  When the integrated information transmitted to the home oxygen therapy management device 130 remains, the data integration unit 122a may set a flag indicating whether or not the information has been transmitted for each unit of integrated information, for example. Further, when deleting the integrated information transmitted to the home oxygen therapy management device 130 from the data storage unit 125, the data integration unit 122a simply determines whether the integrated information is stored in the data storage unit 125. The above determination can be made.

  In step S1180, the data integration unit 122a transmits untransmitted integrated information to the home oxygen therapy management device 130, and proceeds to step S1160.

  In step S1090, the data integration unit 122a outputs an error message indicating that the clock has not been set and integrated information cannot be generated, and the process proceeds to step S1160. The error message is, for example, text or sound of a sentence “cannot perform measurement”.

  By such an operation, the pulse oximeter 120a receives the operation information of the unreceived oxygen concentrator 110a every time it is attached to the cradle 160a, and when the reliability of the oximeter time system is low, The clock can be adjusted with reference to. In addition, the pulse oximeter 120 a can transmit untransmitted integrated information to the home oxygen therapy management device 130 every time it is connected to the home oxygen therapy management device 130. Furthermore, the pulse oximeter 120a can output an error message without generating and transmitting the integrated information when the clock is not set.

  FIG. 11 is a flowchart for explaining the operation of the cradle 160a. Here, the description will be given focusing only on the operation related to the operation information.

  First, in step S2010, the data management unit 162a determines whether new event information has been received from the oxygen concentrator 110a. The data management unit 162a proceeds to step S2020 when new event information is received (S2010: YES), and proceeds to step S2030 when no new event information is received (S2010: NO).

  In step S2020, the data management unit 162a generates operation information in which the received event information (information indicating the start of oxygen supply and the set flow rate value at that time) is associated with the cradle time at the time of reception. The operation information is stored in the data storage unit 165a.

  In step S2040, the data management unit 162a determines whether or not to continue the process related to the operation information. The data management unit 162a returns to step S2010 when the process related to the operation information is continued (S2040: YES), and ends the series of processes when the process related to the operation information is not continued (S2040: NO). That is, every time the cradle 160a receives event information, the cradle 160a generates operation information using the reception time in the cradle time system.

  In step S2030, the data management unit 162a determines whether or not the pulse oximeter 120a is newly attached to the cradle 160a. If the pulse oximeter 120a is newly attached to the cradle 160a (S2030: YES), the data management unit 162a proceeds to step S2050. Further, if the pulse oximeter 120a is not newly attached to the cradle 160a or the state where the pulse oximeter 120a is attached to the cradle 160a continues (S2030: NO), the data management unit 162a proceeds to step S2040.

  In step S2050, the data management unit 162a receives the value of the first flag and the value of the second flag from the pulse oximeter 120a, and exchanges the current time with the pulse oximeter 120a. That is, the data management unit 162a receives the current time based on the oximeter time system from the pulse oximeter 120a together with the flag value indicating the reliability, and transmits the current time based on the cradle time system to the pulse oximeter 120a.

  In step S2060, the data management unit 162a determines whether the first flag of the pulse oximeter 120a is 0 or not. If the first flag is 0 (S2060: YES), the data management unit 162a proceeds to step S2070. If the first flag is 1 (S2060: NO), the data management unit 162a proceeds to step S2040.

  In step S2070, the data management unit 162a determines whether the second flag of the pulse oximeter 120a is zero. When the second flag is 0 (S2070: YES), the data management unit 162a proceeds to step S2090 as it is, and when the second flag is 1 (S2070: NO), the data management unit 162a goes through step S2080 to step S2090. Proceed to

  In step S2080, the data management unit 162a adjusts the cradle time system to the oximeter time system. More specifically, the data management unit 162a adjusts the clock / calendar function unit 163a so that the transmitted current time matches the current time received from the pulse oximeter 120a.

  In step S2090, the data management unit 162a determines whether unsent operation information is stored in the pulse oximeter 120a in the data storage unit 165a. If unsent operation information is stored (S2090: YES), the data management unit 162a proceeds to step S2100. If unsent operation information is not stored (2090: NO), the data management unit 162a proceeds to step S2100. Proceed to S2040.

  When leaving the operation information transmitted to the pulse oximeter 120a, the data storage unit 165a may set a flag indicating whether or not the information is transmitted for each unit of the operation information, for example. Further, when deleting the operation information transmitted to the pulse oximeter 120a from the data storage unit 165a, the data storage unit 165a simply determines whether or not the operation information is stored in the data storage unit 165a. It can be performed.

  In step S2100, the data management unit 162a transmits untransmitted operation information to the pulse oximeter 120a, and proceeds to step S2040.

  By such an operation, the cradle 160a can generate operation information based on the event information received from the oxygen concentrator 110a. In addition, the cradle 160a transmits the operation information of the untransmitted oxygen concentrator 110a every time the pulse oximeter 120a is mounted, and uses the oximeter time system as a reference when the reliability of the oximeter time system is high. The clock can be adjusted. Further, the cradle 160a can stop the transmission of the operation information when the time setting of the pulse oximeter 120a is not performed.

  As described above, the home oxygen therapy management system 100a according to the present embodiment performs the clock adjustment between the cradle 160a and the pulse oximeter 120a, and thus the operation information of the oxygen concentrator 110a and the measurement of the pulse oximeter 120a. The integrated information can be generated in a state where the time system is aligned with the information. In addition, the home oxygen therapy management system 100a detects and records how the clock is set and whether or not the clock is initialized, so that the reliability of the oximeter time system can be easily determined. can do. Moreover, since the home oxygen therapy management system 100a changes the time alignment reference according to the reliability of the oximeter time system, the accuracy of the time axis of the integrated information can be improved. In other words, it becomes possible to more accurately observe the patient's home oxygen therapy.

  The embodiments of the present invention have been described above. The above description is an illustration of a preferred embodiment of the present invention, and the scope of the present invention is not limited to these. That is, the description of the configuration of each device and the operation when using each device is an example, and it is obvious that various modifications and additions to these examples are possible within the scope of the present invention.

  For example, in the second embodiment, the operation information is generated in the cradle. However, similarly to the first embodiment, the operation information may be generated in the oxygen concentrator. In this case, the time adjustment between the concentrator time system and the oximeter time system may be performed between the oxygen concentrator and the pulse oximeter according to the reliability of the oximeter time system. . In this case, a cradle is not necessarily required between the oxygen concentrator and the pulse oximeter if the pulse oximeter can be charged separately. In addition, if the concentrator time system of the oxygen concentrator can be adjusted from the cradle, the cradle treats the event information associated with the concentrator time as operation information as it is, and the concentrator time system and the oximeter time system. You may set the clock in between. Further, a cradle for charging the pulse oximeter may be disposed between the pulse oximeter and the home oxygen therapy management device.

  In the second embodiment, the first flag may be included in the second flag, or the first flag may not be used. In this case, the home oxygen therapy management system may determine the clock adjustment reference based only on the value of the second flag. The means for notifying the cradle of the reliability of the oximeter time system is not limited to the transmission of the flag value. For example, the pulse oximeter transmits the current time according to the oximeter time system to the cradle only when the reliability of the oximeter time system is high. In this case, when the cradle receives the current time based on the oximeter time system, the cradle time system may be adjusted to the oximeter time system. Further, when the reliability of the oximeter time system is low, the pulse oximeter may stop processing without adjusting to the cradle time system.

In each of the above embodiments, one of the biological parameters measured by the pulse oximeter or one of the biological parameters analyzed by the home oxygen therapy management device is arterial oxygen saturation. In a modification, the biological parameter may be arterial oxygen partial pressure (PaO ₂ ). In a further modification of the above embodiment, the arterial oxygen saturation is measured with a pulse oximeter, and the measured value is converted into a value of arterial oxygen partial pressure with a home oxygen therapy management device. Analysis may be performed or vice versa.

  In each of the above embodiments, an oxygen concentrator, which is a type of oxygen supply device that compresses indoor air and generates high-concentration oxygen from the compressed air, is used. Modifications of the above embodiments Then, you may use the oxygen supply apparatus of the type which produces | generates high concentration oxygen from liquid oxygen.

  In each of the above embodiments, the device that conveys the operation information of the oxygen concentrator is a pulse oximeter. However, the present invention is not limited to this. As the device, various biological information measuring devices related to oxygen therapy for measuring other biological parameters such as electrocardiogram, blood pressure, number of steps, activity intensity measured by an acceleration sensor can be adopted.
