After the use of the medical device 500, an operation log as work record data is transmitted to the examination ticket 81 and written by a method described later.

Next, the format of the examination ticket 81 will be described with reference to FIGS.
The symbol CA in FIG. 5 is an IC card before formatting with a built-in non-contact IC tag, and is a blank card before data storage. When this card is also used as a medical examination ticket, only a portion corresponding to the medical care management information is preformatted by the reader / writer 42 connected to the reception terminal 41a of FIG. Then, the recording area for each medical device is used as an examination ticket 81 formatted for each medical device by the reader / writer 46 which is a card issuing device. In the case where it is not used as an examination ticket, the recording area of most of the user area of the IC card is formatted for each medical device by the reader / writer 46 which is a card issuing device. In this case, it becomes an IC card as a portable recording medium in which prescription data is written for each patient other than the examination ticket and work record data (operation log) from the medical device is recorded.
In the following, since the functions and effects of the portable recording medium are the same, a description will be given of an aspect of formatting and recording an IC card that also serves as a medical examination ticket that is more convenient for the patient.

In FIG. 5, the card CA with a built-in non-contact IC tag before formatting can also be used as a medical examination ticket, and is indicated by reference numeral 81-1. As shown in the drawing, the examination ticket 81-1 has a storage area (memory) that is used for the operation of the medical device management system 40 of FIG. 1 or the management apparatus 90 of FIG. (RFID = Radio Frequency Identification) such as a user area 26 which is an information recording area used for a patient individual or used for a patient individual, and a program used for card use such as a communication protocol between an examination ticket 81 and each reader / writer, A card information area 27 for recording information on the format contents, which will be described later, and an apparatus data area 28, which is an information recording area for writing prescription data for medical devices and work records from medical devices. .
Only the device data area 28 is formatted by the reader / writer 46 which is a card issuing device.
Note that the reader / writer existing in various places in the medical device management system in FIG. 1 communicates with the examination ticket 81 as to what information in which area of the recorded information of the examination ticket 81 can be read or written. The authority only for the accessor is determined in advance according to the ID authenticated by. That is, the ID of the person who operates each terminal is confirmed, and only permitted information can be read out. Moreover, even if the record of the user area 26 is read, personal information that should be protected by law is prevented from being read by an unauthorized person.

The examination tickets 81-2, 81-3, 81-4 shown in FIG. 5 respectively show format patterns by the card issuing device. As shown in FIG. Selected by diagnosis of what type of medical device is required. That is, it is determined according to the diagnosis content by the medical staff operating the medical terminal 47 of FIGS.
The prescription data and work record data (operation log) recorded on the card differ depending on the type of equipment. For this reason, the required capacity prepared on the card is determined according to the type of device. This information is held in the device data 93 of the management apparatus 90 in FIG.
In the case shown in the figure, when the total capacity of the device data area 28 allocated for the device in the examination ticket 81-1 is 100. In the format example of the examination ticket 81-2, since the patient uses the medical device X and the medical device Y, the format is set so that the recording capacity is 80 for the medical device X and 20 for the medical device Y.
Similarly, in the format example of the examination ticket 81-3, since the patient uses the medical device X, the medical device Y, and the medical device Z, 60 for the medical device X, 30 for the medical device Y, and for the medical device Z. It is formatted to have 10 recording capacities.
In the format example of the examination ticket 81-4, since the patient only needs to use the medical device Z, it is formatted so that the total capacity 100 of the device data area becomes the recording capacity for the medical device Z.
The contents of these formats are written in the card information area 27 of each examination ticket.

Furthermore, when an increase or decrease occurs in the medical device used by the patient, it is necessary to reformat the card that is the examination ticket 81. During formatting, the data recorded on the storage card is erased.
It is possible to copy the data of the card that is the examination ticket 81 inside the medical terminal 47. Prompt to copy before formatting.
Even using the copied data, it is possible to analyze a prescription result and an operation log which is work record data described later.
However, since the format may be different, copy data cannot be written to the storage card.
After formatting the examination ticket 81, the excess part for each medical device can be arranged and the format can be changed without destroying the current data. Since there is a surplus part, it is premised that the allocation can be adjusted in a direction of increasing the allocation from the current level, so the current data is not destroyed. However, in order to ensure the reliability of data, changes are made according to instructions from the operator.
Since the card issuing system has information on the data structure and variable method of the corresponding device for analyzing the card data, a recommended format can be created so as not to leave a surplus in the allocation area.
In this case, the operator creates a recommended format by selecting the following priority items.
Number of recording days All medical devices shall be allocated so that they can be recorded for the same number of days.
It is thought that waste (residue) often occurs in the data area.
B Set priority medical device data in order Secure the minimum required capacity of the selected device. If the total capacity is exceeded at this point,
Cannot format. In addition to the minimum required capacity, ensure standard recording capacity from high priority medical devices.

FIG. 11 shows items of data that the automatic peritoneal dialysis apparatus 70 writes as work record data on the examination ticket 81.
That is, in the leftmost column of the table of FIG. 11, items of data to be recorded in order from the top are described, and these are recorded in the device memory in the automatic peritoneal dialysis device 70. Data corresponding to each of these items is written in the examination ticket 81 as described in FIG.

The contents of a part of each item of work record data written in the examination ticket 81 are shown in FIGS.
FIG. 12 shows details of “treatment setting history” among the recording items in FIG. FIG. 13 shows details of “treatment result history 1” among the recorded items in FIG. FIG. 14 shows details of “treatment result history 2” among the recorded items in FIG. FIG. 15 shows the details of the “error history” among the recording items in FIG.
In filling all these records, the writing control unit 506 (see FIG. 2) of the medical device makes the following determination regarding the device data area assigned to each medical device of the examination ticket 81.
The device data area has a data capacity that is not substantially excessive or deficient, that is, a storage capacity of information content that is generally required by medical devices, which is a first predetermined capacity, a standard capacity, B capacity (1 to 1 1.2 times). Here, predetermined items (see FIGS. 12, 13, and 14) are stored for a first predetermined number of days (for example, 31 days as one month). The second predetermined capacity, which is larger than the B capacity, is the A capacity (1.2 times or more). Here, the predetermined item (see FIGS. 12, 13, and 14) is the second predetermined number of days. Minutes (for example, 31 days or more as one month or more) are stored. The storage capacity corresponding to the recording of the information content necessary for the medical device to manage the data, for example, the capacity that cannot completely record the recording items or the detailed data included therein is the third predetermined capacity. In this case, a predetermined item (see FIGS. 12, 13, and 14) is stored for a third predetermined number of days (for example, from 15 months to 31 days from 31 months to 1 month). .
The capacity allocated to the medical device (in this case, the automatic peritoneal dialysis device 70) in the device data area of the examination ticket 81 is determined as described above, and whether or not work record data is described is selected. For example, as shown in the flowchart of FIG.

The examination ticket 81-2 in FIG. 6 is an examination ticket prepared for the medical devices X and Y.
In FIG. 7, when the medical device X is operated (ST1) and the examination ticket 81-2 is brought close to the communication range with the medical device X, the medical device X reads the information in the card information area 27 of the examination ticket 81. Therefore, it is confirmed whether it is for the medical device X (or the automatic peritoneal dialysis device 70 in the case where it is the automatic peritoneal dialysis device 70 of FIG. 1) (ST2). If it is determined by the information that it is not, the medical device X does nothing (ST16).

If an affirmative determination is made in step 2, the capacity of the device data area of the examination ticket 81-2 is read (ST3).
Next, whether or not the current capacity of the device data area for the medical device X of the read examination ticket 81-2 satisfies the minimum capacity necessary for writing work record data, for example, corresponds to the above-described C capacity If there is only a capacity that is equal to or less than a predetermined threshold value, “capacity shortage” is determined and the process proceeds to step 15. In this case, the remaining capacity is written (ST15), and the process ends (ST9). Later, the medical terminal looks at the capacity and determines whether the capacity is a surplus capacity that does not reach the writable level.

If it is determined at least in step 4 that “write is possible” (ST4), it is determined whether or not the current capacity of the device data area for the medical device X of the examination ticket 81-2 is the A capacity (ST5). ). When it is determined that the capacity is A, since the medical device X has enough data capacity to be recorded, the write control unit 506 of the medical device 500 in FIG. 2 records the recording contents of the corresponding work record data (operation log). Calculate
For example, the daily required amount of data that can be changed is treatment setting history + treatment result history with 19 cycles + 16 error histories.
The recordable days in which data can be recorded is an integer part of (storable capacity−capacity of a fixed part) / daily required amount of variable data).
Therefore, since the capacity required for recording is (fixed part) + (variable data), recording of apparatus setting + treatment parameter 1 + treatment parameter 2 + treatment setting + treatment setting history + treatment result history with 19 cycles + error history) This is the number of possible days (see FIGS. 11 to 15).
However, the error history will be 500 or more in 16 cases per day. Further, for example, the upper limit of the recordable days is 366 days (error history is 5856) (ST12).

  Subsequently, the record data based on the calculation result is written in the examination ticket 81-2 (ST13). Next, it is determined whether or not there is a capacity for further recording in the recording area (ST14), and if there is no capacity, the process ends (ST9). If it is determined in step 14 that there is a remaining capacity, the process proceeds to step 15. In this case, the remaining capacity is written (ST15), and the process ends (ST9).

If the current capacity of the device data area for the medical device X of the examination ticket 81-2 is not determined as the above-described A capacity in Step 5, the current capacity of the device data area for the medical device X is as described above. It is determined whether the capacity is B (ST6).
If it is determined that the capacity is B, the medical device X has a sufficient amount of data that can be recorded, and therefore calculates the recording content of the corresponding work recording data (operation log) (ST10).
However, since the B capacity is a predetermined standard storage capacity, data recording in the case of the B capacity is performed as shown in FIGS. 11 to 15 (ST11). Thereafter, the process proceeds to step 14 described above.

If the current capacity of the device data area for the medical device X of the examination ticket 81-2 is not determined as the above-described B capacity in step 6, the current capacity of the device data area for the medical device X is Since the capacity is C, the writing control unit 506 of the medical device 500 in FIG. 2 performs calculation related to the reduction of the recording data (ST7).
For example, the daily required recording amount of variable data is treatment setting history + treatment result history with 8 or 19 cycles.
The recordable days is an integer part of (storable capacity−capacity of fixed part) / daily required amount of variable data).
Therefore, the capacity required for recording is (fixed part) + (variable data) part and the number of days that can be recorded (apparatus setting + treatment parameter 1 + treatment parameter 2 + treatment setting + 500 error history) and (treatment setting) This is the number of days that can be recorded (history + history of treatment results with 8 or 19 cycles) (see FIGS. 11 to 15).
Next, the recording data based on the calculation result is written in the examination ticket 81-2 (ST8), and the process ends (ST9).

As described in the above work flow, recording is performed as shown in FIG.
That is, after the patient has undergone the prescribed treatment, the medical device X writes the work record data in the device data area 28-1. In this case, items and contents to be written for each device are determined as described later. Therefore, it is determined whether or not the operation log, which is the work record data, can be recorded within the capacity confirmed in the device data area 28-1. If the capacity of the device data area 28-1 is insufficient to record all the work record data, the medical device X changes to data content that can be written with a smaller capacity than previously determined or less data prepared in advance. The amount information is selected and written in the device data area 28-1.
In this case, even the smallest amount of data that can be selected or adjusted by the medical device X cannot be written when the capacity of the device data area 28-1 of the examination ticket 81-2 is insufficient or when the remaining capacity is zero.

Similarly, when the medical device Y is operated and the examination ticket 81-2 is brought close to a communication range with the medical device Y, the medical device Y reads the information in the card information area 27 of the examination ticket 81, It is read that the capacity of the device data area for the medical device Y is 20.
Then, after the patient has received the prescribed treatment, the medical device Y writes the work record data in the device data area 28-2. Also in this case, the medical device Y determines whether or not the operation log that is the work record data can be recorded within the capacity confirmed in the device data area 28-2. If the capacity of the device data area 28-2 is not enough to record all the work record data, the medical device Y is changed to data content that can be written with a smaller capacity than previously determined or data that is less than prepared. The amount information is selected and written in the device data area 28-2.

In this case, the smallest data amount that can be selected or adjusted by the medical device Y cannot be written if the capacity of the device data area 28-2 of the examination ticket 81-2 is insufficient or the remaining capacity is zero.
However, if the medical device Z is operated and the examination ticket 81-2 is brought close to the communication range with the medical device Z, the medical device Z reads the information in the card information area 27 of the examination ticket 81, It is read that the capacity of the device data area for the medical device Z is zero.
Therefore, the medical device Z cannot be used by the examination ticket 81-2.

The noise sensor 15 and the noise sensor detection circuit unit 61 are provided. The two microphones 13 and 14 are electrically connected to the control system 56 via the K sound detection circuit unit 60.

  The two microphones 13 and 14 detect the blood flow sound (blood vessel information) of the measurer, and the K sound detection circuit unit 60 detects the K sound from the blood flow sound and transmits the K sound signal to the control system 56. The control system 56 detects the Korotkoff sound, the generation point and the disappearance point of the Korotkoff sound from the input K sound signal. The noise sensor 15 detects vibration noise that enters the microphones 13 and 14 from the outside, and sends a noise signal to the control system 56 via the noise sensor detection circuit unit 61. Thereby, the control system 56 improves the accuracy of the K sound detection signal by removing noise from the K sound signal.

In the electronic sphygmomanometer 100, the cuff in the armband is pressurized by the pumps 44 and 45, and then the pressure of the cuff in the armband is detected by using the pressure sensor 64 while exhausting and depressurizing at a low speed, and at the same time, the microphone. Is used to detect the Korotkoff sound (K sound). The electronic sphygmomanometer 100 detects the K sound signal, the generation point and the disappearance point of the K sound signal, thereby calculating the maximum blood pressure value and the minimum blood pressure value, and the calculated maximum blood pressure value and the minimum blood pressure value. Can be displayed on the display unit 31.

  Next, the exhaust system 52 will be described. The exhaust system 52 includes two drive units 66 and 67, an exhaust valve (forced exhaust unit), and a control valve (decompression control unit). The exhaust valve and the control valve are arranged in the middle of the piping part 63.

The oxygen concentrator 120 shown in FIG. 17 uses, for example, a compressed aerodynamic fluctuation adsorption method (PSA: positive pressure fluctuation adsorption method) using compressed air as an oxygen generation principle.
In the positive pressure fluctuation adsorption method using only compressed air, only compressed air is sent into the adsorption cylinder to adsorb nitrogen. The positive pressure fluctuation adsorption method has an advantage that the compressor can be made smaller and lighter than the positive and negative pressure fluctuation adsorption method (VPSA) using compressed air and reduced pressure air.

A double line shown in FIG. 17 indicates a pipe serving as a flow path for raw material air, oxygen, and nitrogen gas. A thin solid line indicates power supply or electric signal wiring. The main casing 2 of the oxygen concentrator 1 shown in FIG. 17 is indicated by a broken line, and the main casing 2 is a sealed container that seals the elements arranged inside. The main housing 2 is an injection-molded resin product, for example, and is made of a thermoplastic resin having impact resistance.
The main housing 2 shown in FIG. 17 has an intake port 2c for introducing raw material air, which is outside air, and an exhaust port 2b for exhausting. A filter 3 for removing impurities such as dust in the air is disposed at the intake port 2c. When the compressor 10 is operated, the raw material air passes through the filter 3 of the intake port 2c along the F direction. Is introduced into the compressor 10 through the pipe 4.

  The raw air is introduced into the compressor 10 via the pipe 4 and compressed to become compressed air, but heat is generated when the raw air is compressed. For this reason, the compressed air discharged from the compressor 10 is cooled by the rotation of the blower fan 5. By cooling the compressed air in this way, the temperature rise of the zeolite, which is an adsorbent that declines in function at high temperatures, can be suppressed, so that it functions sufficiently as an adsorbent for generating oxygen by adsorption of nitrogen. As a result, oxygen can be concentrated to about 90% or more.

  The first adsorption cylinder 108a and the second adsorption cylinder 108b are examples of adsorption members, and are arranged in parallel in the vertical direction. Three-way switching valves 109a and 109b as switching valves are connected to the first adsorption cylinder body 108a and the second adsorption cylinder body 108b, respectively. Of these switching valves, one end of the three-way switching valve 109 a is connected to the pipe 6. Further, the three-way switching valve 109 a and the three-way switching valve 109 b are connected to each other, and one end of the three-way switching valve 109 b is connected to the pipe 7.

  The pipe 7 and the pipe 6 are connected to each other. The pipe 7 is connected to the pipe 6 in order to perform a purification process for desorbing unnecessary gas in the first adsorption cylinder body 108a and the second adsorption cylinder body 108b. The three-way switching valves 109a and 109b are connected to the first adsorption cylinder 108a and the second adsorption cylinder 108b, respectively. The compressed air generated from the compressor 10 is alternately supplied to the first adsorption cylinder body 108a and the second adsorption cylinder body 108b via the pipe 6 and the three-way switching valves 109a and 109b.

Zeolite as a catalyst adsorbent is stored in the first adsorption cylinder 108a and the second adsorption cylinder 108b, respectively. This zeolite is, for example, an X-type zeolite having a Si ₂ O ₃ / Al ₂ O ₃ ratio of 2.0 to 3.0, and at least 88% or more of this Al ₂ O ₃ tetrahedral unit is composed of lithium cations. By using the bonded one, the adsorption amount of nitrogen per unit weight can be increased. This zeolite preferably has a granule measurement value of less than 1 mm, and at least 88% of tetrahedral units are fused with lithium cations. By using zeolite, it becomes possible to reduce the amount of raw material air used for generating oxygen compared to the case of using other adsorbents. As a result, the compressor 10 for generating compressed air can be reduced in size and weight, and the noise of the compressor 10 can be reduced.

  As shown in FIG. 17, an equal pressure valve 107 including a check valve, a throttle valve, and an on-off valve is connected to the outlet side of the first adsorption cylinder body 108a and the second adsorption cylinder body 108b. A pipe 8 to be joined is connected to the downstream side of the equal pressure valve 107, and a product tank 111 is connected to the pipe 8. The product tank 111 is a container for storing oxygen having a concentration of about 90% or more generated by separation in the first adsorption cylinder 108a and the second adsorption cylinder 108b.

  As shown in FIG. 17, a pressure regulator 112 is connected to the downstream side of the product tank 111, and the pressure regulator 112 is a regulator that automatically adjusts the oxygen pressure on the outlet side of the product tank 111 to be constant. . A zirconia-type or ultrasonic-type oxygen concentration sensor 114 is connected to the downstream side of the pressure regulator 112, and the oxygen concentration sensor 114 detects the oxygen concentration intermittently (every 10 to 30 minutes) or It is designed to be performed continuously.

As shown in FIG. 17, a proportional opening degree valve 115 is connected to the oxygen concentration sensor 114. This proportional opening valve 115 opens and closes in response to a setting button operation of the oxygen flow rate setting button 308 in accordance with a signal from the flow rate control unit 202 according to a command from the central control unit 200. An oxygen flow rate sensor 116 is connected to the proportional opening valve 115. A demand valve 117 is connected to the oxygen flow rate sensor 116 via a reduced pressure air circuit board for breathing synchronization control, and the demand valve 117 is connected to the oxygen outlet 9 of the oxygen concentrator 120 through a sterilization filter 119. ing.
The adapter 313 of the nasal cannula 314 is detachably connected to the oxygen outlet 9. Adapter 313 is connected to nasal cannula 314 via tube 315. The patient can inhale oxygen concentrated to about 90% or more through the nasal cannula 314, for example, at a maximum flow rate of 1 L / min. By controlling the demand valve 117 and performing respiratory synchronization control, generally considering that the IE ratio (ratio of inspiratory time (seconds) to expiratory time (seconds)) is 1: 2, by respiratory synchronous control, This is equivalent to the effect of supplying the patient with oxygen concentrated to 90% or more at a maximum rate of 3 L / min.

Next, the power supply system shown in FIG. 17 will be described.
17 is electrically connected to a switching regulator type AC adapter 419, and the AC adapter 419 rectifies the AC voltage of the commercial AC power source into a predetermined DC voltage.

  Accordingly, the central control unit 200 in FIG. 17 controls the power supply control circuit 226, so that the power supply control circuit 226 receives the power supply from the AC adapter 419 and the built-in battery 228. Automatically in one of a total of three power supply states: a second power supply state that operates by receiving power supply from the battery, and a third power supply state that operates by receiving power supply from the external battery 227 Can be used by switching. The built-in battery 228 and the external battery 227 are preferably lithium ion or lithium hydrogen ion secondary batteries that have little memory effect during charging and can be fully charged even during recharging, but may be conventional nickel cadmium batteries or nickel metal hydride batteries. Further, in preparation for an emergency, the external battery 227 may be configured as a box of, for example, an AA battery that can be obtained anywhere.
