Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a continuous blood pressure measuring device for dialysis for repeatedly measuring the blood pressure value of a living body undergoing hemodialysis.

[0002]

[Prior art]

 According to the preset blood pressure measurement procedure, for example, pressurization of the cuff, gradual depressurization of the cuff, detection of pulse wave or Korotkoff sound generated during the gradual depressurization, change of pulse wave or Korotkoff sound 2. Description of the Related Art There is known an automatic blood pressure measuring device that automatically measures the blood pressure of a living body by sequentially determining the blood pressure value according to a predetermined blood pressure value determination algorithm based on the occurrence and disappearance and releasing the cuff when the blood pressure measurement is completed. A continuous automatic blood pressure measurement device of the type in which the automatic blood pressure measurement operation of such an automatic blood pressure measurement device is repeatedly activated at a preset activation cycle has also been proposed.

[0003]

[Issues to be solved by the device]

 By the way, in the hemodialysis of a living body, in order to monitor the blood pressure value during a dialysis period of about 4 to 5 hours, the continuous automatic blood pressure measuring device as described above is used. However, if a continuous automatic blood pressure measurement device is used, the blood pressure measurement cycle is constant, so the delay time from the sudden change in the blood pressure value of the living body to the time when it is known may be relatively long. It was difficult to carry out the procedure. That is, if the blood pressure measurement cycle is set to be short, the delay time from the sudden change in the blood pressure value of the living body until it is known is relatively shortened, while the blood pressure measurement is performed over the entire dialysis period of about 4 to 5 hours in that short cycle. If this is done, the frequency of compression of the living body by the cuff will increase and the burden on the living body will increase. Therefore, it is unavoidable to set the measurement cycle to about 20 to 30 minutes, for example.

As a result of various studies conducted by the present inventors against the above-mentioned circumstances, there is a phenomenon that blood pressure fluctuations in a living body within the hemodialysis period are concentrated at the beginning and end of the dialysis period. Since there is an intermediate stable period in which the blood pressure change is small and stable between the initial change period and the end change period, which have large fluctuations, and an intermediate period between them, the blood pressure measurement cycle in the initial change period and the end change period with large blood pressure changes is set short. By setting a relatively long blood pressure measurement period during the intermediate stable period in which the blood pressure fluctuation is small, it is possible to accurately know the sudden change in the blood pressure value of the living body during dialysis, and at the same time, reduce the burden on the living body. I was found to be done. The present invention was made based on such knowledge.

[0005]

[Means for Solving the Problems]

 That is, an object of the present invention is to provide a continuous dialysis automatic blood pressure measuring device for dialysis, which can accurately know a sudden change in the blood pressure value of the living body during dialysis, and which reduces the burden on the living body. In order to achieve such an object, the gist of the present invention is to provide a blood pressure measuring means for automatically measuring the blood pressure value of the living body, and to measure the blood pressure value of the living body undergoing hemodialysis at a predetermined starting cycle. A continuous blood pressure measuring device for dialysis for continuous measurement in (a) until the elapsed time from the start of continuous blood pressure measurement exceeds a preset first judgment reference value. The period and the elapsed time from the start of the continuous blood pressure measurement exceed the second judgment reference value and at least one of the end periods until the blood pressure measurement is completed, the first preset time is set. At the start-up cycle A short-cycle activation means for activating, and (b) the elapsed time from the start of the continuous blood pressure measurement exceeds the first determination reference value and is set to a value larger than the first determination reference value. The intermediate period until the second determination reference value is exceeded includes long cycle activation means for activating the blood pressure measurement means in the second activation cycle set longer than the first activation cycle. .

[0006]

[Action]

 In this way, the start time until the continuous blood pressure measurement is started until the time exceeds the preset first judgment reference value and the elapsed time after the continuous blood pressure measurement is started. Is above the second judgment reference value and at least one of the end periods until the blood pressure measurement is completed, the short-cycle activation means activates the blood pressure measurement means at a preset first activation cycle. , The intermediate time until the elapsed time from the start of the continuous blood pressure measurement exceeds the first judgment reference value and exceeds the second judgment reference value set to a value larger than the first judgment reference value. In the period, the long-cycle activation means activates the blood pressure measurement means in the second activation cycle that is set longer than the first activation cycle.

[0007]

[Effect of device]

 According to the present invention, the first judgment reference value is set between the initial fluctuation period and the intermediate stable period during dialysis, and the second judgment reference value is set between the intermediate stable period and the terminal fluctuation period. As a result, the blood pressure measurement is repeated with a relatively long activation period during the intermediate stable period, but during the initial fluctuation period and the terminal fluctuation period, the blood pressure measurement is performed with a shorter activation period than the intermediate stable period. In at least one of the initial fluctuation period and the terminal fluctuation period, in which the blood pressure occurs intensively, the blood pressure fluctuation of the living body can be quickly detected by measuring the short activation period, while the comparison is made in the intermediate stable period where the time ratio is relatively large. The load on the living body can be greatly reduced by measuring the long activation period. Therefore, during dialysis, a sudden change in the blood pressure value of the living body can be accurately known, and the burden on the living body can be reduced.

[0008]

[Other aspects of the invention]

 Here, the short cycle starting means sets the first starting cycle set in advance in the starting period until the elapsed time from the start of the continuous blood pressure measurement exceeds the first judgment reference value set in advance. Activates the blood pressure measuring means. Alternatively, the short-cycle activation means sets a preset first time during an end period until the time elapsed from the start of continuous blood pressure measurement exceeds the second determination reference value and the blood pressure measurement ends. The blood pressure measuring means is activated in the activation cycle. In this way, during the initial fluctuation period or terminal fluctuation period during which blood pressure fluctuations concentrate during the hemodialysis period, it is possible to quickly know the blood pressure fluctuations in the living body by measuring the short activation cycle, but at a relatively long time. In the middle stable period where the ratio is high, the burden on the living body can be greatly reduced by measuring a relatively long activation period.

Further, the short-cycle activating means starts the continuous blood pressure measurement and the start period until the elapsed time from the start of the continuous blood pressure measurement exceeds a preset first judgment reference value. The blood pressure measuring means is activated at the preset first activation period during the end period until the elapsed time after the measurement exceeds the second judgment reference value and the blood pressure measurement is terminated. By doing so, during the initial fluctuation period and the terminal fluctuation period during which the blood pressure fluctuations occur intensively during the hemodialysis period, it is possible to quickly know the blood pressure fluctuations in the living body by measuring the short activation cycle, but at a comparatively long time rate. In the middle stable period with a large value, the load on the living body can be greatly reduced by measuring a relatively long activation period.

[0012] Preferably, a display unit for displaying the blood pressure value repeatedly measured by the blood pressure measurement unit and the current time along a common time axis is further included. With this configuration, the display unit displays the blood pressure value repeatedly measured by the blood pressure measurement unit and the current time along a common time axis. Therefore, the blood pressure measurement value and its change during dialysis can be easily known, and the position of the current time during the dialysis period can be easily known, which facilitates the management during the dialysis by the medical staff. At the same time, it is possible to eliminate the anxiety of the living body itself.

【Example】

 Hereinafter, a continuous blood pressure measuring device for dialysis, which is an embodiment of the present invention, will be described in detail with reference to the drawings.

FIG. 1 is a block diagram illustrating the configuration of a continuous blood pressure measuring device for dialysis. In FIG. 1, a cuff 10 wrapped around an upper arm of a living body is compressed and accommodated in a non-stretchable arm band 10b of an inflatable bag 10a made of an elastic film such as a rubber sheet or a vinyl sheet. It is configured by The inflation bag 10a of the cuff 10 is connected to the pressure sensor 12, the air pump 14, the pressure control valve 16 and the air pipe 18.

The pressure sensor 12 includes, for example, a semiconductor pressure detecting element, detects the pressure in the cuff 10, and supplies a pressure signal SP representing the pressure to the low pass filter 20 and the band pass filter 22. . The low-pass filter 20 discriminates the DC component contained in the pressure signal SP 1 to take out the pressure (static pressure) P _C of the cuff 10, and outputs it to the A / D converter 24 as a cuff pressure signal SK. Further, the bandpass filter 22 discriminates a frequency component of, for example, 1 to 10 Hz included in the pressure signal SP, extracts a pulse wave component, and outputs it as a pulse wave signal SM1 to the A / D converter 24. In the cuff 10 wrapped around the upper arm of the living body, pressure fluctuations synchronized with the heartbeat are generated based on the pulsation of the artery.

The bandpass filter 22 is a pressure wave generated in the cuff 10 in synchronization with the heartbeat during the gradual pressure change (2 to 3 mmHg / sec) of the pressure of the cuff 10 for blood pressure measurement, that is, a pulse wave. It has a narrow frequency characteristic for extracting the amplitude without the influence of noise such as motion artifact noise. The A / D converter 24 includes a multiplexer that time-divisions the two types of input signals, and has a function of A / D converting the two types of input signals in parallel. There is.

The arithmetic and control unit 26 is a so-called microcomputer including a CPU 28, a RAM 30, a ROM 32, an output interface 34, and a display interface 36. The CPU 28 receives the signal input from the A / D converter 24 from the RAM 30. While utilizing the temporary storage function of the device, processing is performed according to a program stored in advance in the ROM 32, the air pump 14 and the pressure control valve 16 are driven and controlled through the output interface 34, and the display interface 36 is used for display. Drive control of 38. The display 38 is provided with an image display plate for displaying the blood pressure measurement value and the current time by a large number of pixels, and is also equipped with a numerical display element capable of displaying the blood pressure measurement value and the current time in numbers, if necessary. To be FIG. 2 shows an example of image display by the display 38.

The manual automatic selection switch 39 is operated to manually activate the blood pressure measurement or automatically activate the blood pressure measurement. The mode switch 40 is operated to switch between the normal measurement mode and the dialysis measurement mode, and selectively supplies a signal instructing the normal measurement mode or the dialysis measurement mode to the CPU 28. The dialysis program setter 42 is operated to select a dialysis program when the mode is switched to the dialysis measurement mode. The A program (3 hours), B program (4 hours), C program. A signal for instructing any one of (5 hours) is selectively supplied to the CPU 28. The measurement cycle setter 44 is operated to set the measurement cycle when it is normally switched to the measurement mode, and selectively supplies a signal instructing the measurement cycle to the CPU 28. The start / stop switch 46 supplies the CPU 28 with a signal for alternately instructing the start and stop of continuous blood pressure measurement for each operation.

FIG. 3 is a functional block diagram for explaining a main part of the control function of the arithmetic and control unit 26. The elapsed time counting means 48 counts clock pulses output from, for example, a clock circuit (not shown) after the dialysis measurement mode is selected by the mode switch 40 and the start of continuous blood pressure measurement is operated by the start / stop switch 46. It is composed of a counter (not shown), etc., and measures the elapsed time ET after the dialysis measurement mode is selected and the operation of continuous blood pressure measurement is operated. The blood pressure measuring means 50 executes the preset blood pressure measurement program in sequence, and based on the heartbeat synchronizing signal generated from the living body in the process of changing the compression pressure of the cuff 10 wrapped around a part of the living body. Automatically measure the blood pressure value of the living body. For example, the blood pressure measuring means 50 determines the cuff pressure at the time of occurrence and disappearance of Korotkoff sound generated from the artery compressed in the process of gradually changing the compression pressure of the cuff 10 as the maximum blood pressure value and the minimum blood pressure value. To do. Alternatively, the blood pressure measuring means 50 determines the cuff pressure at the time when the pulse wave, which is the pressure oscillation of the cuff 10 that is generated during the process of gently changing the compression pressure of the cuff 10, abruptly changes to the maximum blood pressure value and the minimum blood pressure value. To do.

The short cycle starting means 51 comprises a first short cycle starting means 52 and a second short cycle starting means 56. The first short cycle activating means 52 has a first judgment reference value T for which an elapsed time ET from the start of continuous blood pressure measurement in the dialysis measurement mode is preset.₁Start period D until exceeds₁In, the first start-up cycle I set in advance₁The blood pressure measuring means 50 is activated with. The long cycle starting means 54 determines that the elapsed time ET from the start of continuous blood pressure measurement in the dialysis measurement mode is the first determination reference value T.₁And the first judgment reference value T₁The second judgment reference value T set to a value larger than₂ Second period D before exceeding₂Is the first activation cycle I₁Second activation cycle I set to be longer than₁Activates blood pressure measuring means 50. The second short cycle activating means 56 determines that the elapsed time ET from the start of continuous blood pressure measurement in the dialysis measurement mode is the second judgment reference value T.₂End period D until the blood pressure measurement in dialysis measurement mode is completed₃At the second start cycle I₂The third activation cycle I set to be shorter than ₃ Activates blood pressure measuring means 50.

The display means 58 corresponds to the dialysis program set by the dialysis program setting device 42, that is, any one of the A program (3 hours), the B program (4 hours), and the C program (5 hours). The time axis 60 of the length is displayed on the screen of the display 38, and the blood pressure value repeatedly measured by the blood pressure measuring means 50 during the dialysis period and the current time are displayed along the common time axis 60 on the screen. To display.

FIG. 4 and FIG. 5 are flow charts for explaining a main part of the control operation of the arithmetic and control unit 26. FIG. 4 shows a blood pressure measurement routine by the oscillometric method, and FIG. 5 shows an activation control routine for automatically starting execution of the blood pressure measurement routine. This startup control routine is executed only when automatic is selected by the manual automatic selection switch 39.

In step SA1 in FIG. 4 (hereinafter omitted), it is determined whether or not the activation determination (activation output) in FIG. 5 has been made. If the determination of SA1 is denied, this routine is ended, but if the determination is affirmative, the air pump 14 is started and the pressure control valve 16 is set to the pressure increasing side in SA2 for blood pressure measurement. The pressurization of the cuff 10 is started. In the subsequent SA3, the pressure P of the cuff 10 _C Is a preset reference value P₁It is determined whether or not the above is reached. This judgment reference value P₁Is set to a fixed value higher than the systolic blood pressure value of the subject, for example, a value of about 180 mmHg, or a predetermined value higher than the systolic blood pressure value measured last time.

When the determination in SA3 is negative, the pressure P _{C of the} cuff 10 is kept on standby until it reaches the determination reference value P ₁ or more, but when the determination is affirmative, the air pump 14 is stopped in SA4. After the pressurization of the cuff 10 is stopped by this, the pressure control valve 16 is set to the slow exhaust side in SA5, so that the pressure of the cuff at the pressure reducing rate for measuring the blood pressure, for example, 2 to 3 mmHg / sec. The compression pressure of 10 is gradually reduced.

Next, at SA6, it is determined whether or not a pulse wave, which is pressure oscillation generated in synchronization with the pulse, is generated in the cuff 10, that is, whether or not the pulse wave signal SM1 is input. When the determination of SA6 is negative, the above SA5 and subsequent steps are repeatedly executed, but when the determination is affirmative, the blood pressure determination routine of SA7 is executed. In this blood pressure determination routine, a well-known oscillometric blood pressure determination algorithm is executed, for example, the inflection point in the curve showing the cuff pressure and the magnitude of the pulse wave amplitude, that is, the difference between the pulse wave amplitudes is the maximum value. Is determined as the systolic blood pressure value and the diastolic blood pressure value, and the cuff pressure at the point where the pulse wave amplitude has the maximum value is determined as the mean blood pressure value.

In the subsequent SA8, it is determined whether or not all blood pressure values, that is, the maximum blood pressure value, the average blood pressure value, and the minimum blood pressure value have been determined by executing the blood pressure determination routine. If the determination in SA8 is negative, the above SA5 and subsequent steps are repeatedly executed, but if the determination is affirmative, in SA9, for example, as shown in FIG. 2, the blood pressure value determined by the execution of the above blood pressure determination routine. And the current time is displayed on the display 38. In FIG. 2, a bar-shaped blood pressure display line 64 indicating a blood pressure value corresponds to the blood pressure measurement time on the time axis 60 in the two-dimensional coordinates including the time axis 60 that is the horizontal axis and the blood pressure value axis 62 that is the vertical axis. The length is determined so that it is displayed at the position and the upper and lower ends indicate the systolic blood pressure value and the diastolic blood pressure value, respectively. In addition, in the two-dimensional coordinates, a broken line time display line 66 indicating the current time is displayed at a position corresponding to the blood pressure measurement time on the time axis 60 based on the elapsed time ET. Further, one of the time axes 60 constituting the above two-dimensional coordinates corresponds to one of the programs set by the dialysis program setting unit 42, and its time display span corresponds to the dialysis time. The time axis 60 in FIG. 2 shows the state in which the B program is set, and the time display span is from 0 to 4 hours. In the present embodiment, SA1 to SA8 correspond to the blood pressure measuring means 50, and SA9 corresponds to the display means 58.

In the startup control routine of FIG. 5 executed in series or in parallel with the blood pressure measurement routine of FIG. 4, whether the dialysis measurement mode is selected in SB1 depends on the operation state of the mode switch 40. It is judged based on. If the determination at SB1 is negative, the normal measurement mode is selected, so at SB2, this routine is executed after the start output is performed at the set cycle set by the measurement cycle setting device 44. Can be terminated. As a result, the blood pressure measurement is continuously executed at each set cycle.

However, if the determination in SB1 is affirmative, in SB3, the first determination in which the dialysis measurement mode is selected and the elapsed time ET after the activation operation is performed by the activation stop switch 46 is preset is made. It is determined whether or not the reference value T _{1 is} exceeded. The first judgment reference value T ₁ is set in advance to, for example, about 60 minutes so as to be between the initial fluctuation period and the intermediate stable period during dialysis of the living body.

If the determination in SB3 is negative, it is considered that the initial fluctuation period is still in effect, so that in SB4 corresponding to the first short cycle activation means 52, the blood pressure fluctuation is large in the initial fluctuation period. In order to start the blood pressure measurement routine of FIG. 4, the first start cycle I _{1 is} set to be relatively short so that the blood pressure measurement routine of FIG. 4 is started in the start cycle of about 10 to 15 minutes. The output is repeated.

[0028] If the determination in SB3 is affirmative, it is unclear whether it is within the intermediate stable period or the end-fluctuation period although it has passed the initial fluctuation period during dialysis of the living body, and therefore SB5 At, it is determined whether the elapsed time ET has become equal to or greater than the preset second determination reference value T ₂ . The second judgment reference value T ₂ is preset to, for example, about 120 minutes so as to be between the intermediate stable period and the terminal fluctuation period during dialysis of the living body.

If the determination at SB5 is negative, it is considered that the period is still within the intermediate stable period. Therefore, at SB6 corresponding to the long cycle starting means 54, within the intermediate stable period during which the blood pressure fluctuation is stable. In the second activation cycle I ₂ which is set comparatively long, for example, to reduce the burden on the living body due to the compression of the cuff 10 as much as possible within a range in which the blood pressure fluctuation of the living body can be known to be necessary and sufficient, The activation output for activating the blood pressure measurement routine of FIG. 4 is repeatedly performed at an activation cycle of about 60 minutes.

However, if the determination at SB5 is affirmative, it is considered that it is within the terminal fluctuation period, and therefore at SB7 corresponding to the second short cycle starting means 56, within the terminal fluctuation period where the blood pressure fluctuation is large. A third activation cycle I ₃ set to be relatively short so that the blood pressure fluctuation can be known relatively quickly, for example, an activation output for activating the blood pressure measurement routine of FIG. 4 at an activation cycle of about 10 to 15 minutes. Is repeated.

As described above, according to the present embodiment, in the dialysis measurement mode, the initial time until the elapsed time ET from the start of continuous blood pressure measurement exceeds the preset first determination reference value T _1. During the change period, the execution of SA1 to SA8 corresponding to the blood pressure measurement means 50 is activated by the SB4 corresponding to the first short cycle activation means 52 at the preset first activation cycle I ₁ , and the elapsed time ET is , The intermediate stable period until exceeding the first judgment reference value T ₁ and exceeding the second judgment reference value T ₂ set to a value larger than the first judgment reference value T ₁ corresponds to the long cycle starting means 54. SB6 causes the blood pressure measuring means 50 to be activated in the second activation cycle I ₂ which is set longer than the first activation period I ₁ , and the elapsed time ET exceeds the second determination reference value T ₂ and the blood pressure is exceeded. End change until measurement is completed Period, by SB7 corresponding to the second short period starting means 56, the blood pressure measuring means 50 is caused to start in the third activation period I ₃ which is the second set to be shorter than the activation cycle I _2. As a result, according to this example, the blood pressure measurement is repeated at a relatively long cycle during the intermediate stable period, but the blood pressure measurement is performed at a cycle shorter than the intermediate stable period during the initial fluctuation period and the terminal fluctuation period. In the initial fluctuation period and the terminal fluctuation period in which blood pressure fluctuations occur intensively, it is possible to quickly know the blood pressure fluctuations of the living body by measuring a short cycle, while in the intermediate stable period where the time ratio is relatively large, it is relatively long By measuring the cycle, the burden on the living body can be greatly reduced. Therefore, during dialysis, a sudden change in the blood pressure value of the living body can be accurately known and the burden on the living body is reduced.

Further, according to the present embodiment, the blood pressure display line 64 indicating the blood pressure value measured by executing SA1 to SA8 corresponding to the blood pressure measurement means 50 by the SA9 corresponding to the display means 58 and the current time. Is displayed along the common time axis 60, the blood pressure measurement value and its change during dialysis can be easily known, and the position of the current time in the dialysis period can be easily known. As a result, the medical staff can easily manage during dialysis, and at the same time, the anxiety of the living body can be eliminated.

Although one embodiment of the present invention has been described above with reference to the drawings, the present invention can be applied to other aspects.

For example, in the above-mentioned embodiment, the first short cycle starting means 52 and the second short cycle starting means 56 are provided, but even if either one is removed, a temporary effect can be obtained.

Further, in the above-described embodiment, the first activation period I ₁ and the third activation period I ₃ are set to about 10 to 15 minutes, and the second activation period I ₂ is about 50 to 60 minutes. It was set to, but is not necessarily limited to that number.

In the above-described embodiment, the blood pressure display line 64 is used to display the measured blood pressure value at the two-dimensional coordinates displayed on the display 38, and the time is displayed to display the current time. Although the display line 66 is used, other symbols such as ◯ mark, Δ mark, and X mark may be used.

Further, in the blood pressure measuring means 50 of the above-described embodiment, the blood pressure measurement is performed by the so-called oscillometric method, but it does not matter if the blood pressure measurement is performed by the Korotkoff sound method.

The above description is merely an embodiment of the present invention, and the present invention can be variously modified without departing from the gist thereof.
