Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The exercise support device according to the first embodiment can support the exercise performed by the patient during the blood purification treatment, and as shown in FIG. 1, the blood dialysis device 1 for performing the blood purification treatment (dialysis treatment). The blood volume meter 2 and the sphygmomanometer 3 arranged in the above, the exercise means S, the input means 4, the determination means 5, the notification means 6, and the monitoring means 7 are provided.

As shown in FIGS. 2 and 3, the hemodialysis apparatus 1 applied to the present embodiment has a blood circuit 8 for circulating the patient's blood extracorporeally and is connected to the blood circuit 8 to perform a hemodialysis treatment. The dialyzer 9 is mainly composed of a dialyzer main body 12 which is connected to the dialyzer 9 and removes water while supplying dialysate. As shown in the figure, the blood circuit 8 is mainly composed of an arterial blood circuit 8a and a venous blood circuit 8b made of a flexible tube, and the arterial blood circuit 8a and the venous blood circuit 8a. A dialyzer 9 is connected between 8b.

An arterial puncture needle a is connected to the tip of the arterial blood circuit 8a, and an ironing type blood pump 10 and a hematocrit sensor 15 are arranged in the middle of the arterial blood circuit 8a. On the other hand, the venous side blood circuit 8b is connected to the venous side puncture needle b at the tip thereof, and the air trap chamber 11 for defoaming is connected in the middle. In the present specification, the side of the puncture needle for removing blood (collecting blood) is referred to as "arterial side", and the side of the puncture needle for returning blood is referred to as "venous side". "And" venous side "does not mean that the blood vessel to be punctured is defined by either an artery or a vein.

Then, when the blood pump 10 is driven with the arterial puncture needle a and the venous puncture needle b punctured by the patient, the patient's blood reaches the dialyzer 9 through the arterial blood circuit 8a and reaches the dialyzer 9. The blood is purified by the blood trap chamber 11 and returned to the patient's body through the venous blood circuit 8b while being defoamed. In this way, the patient's blood is circulated extracorporeally in the blood circuit 8 and purified by the dialyzer 9.

The dialyzer 9 is formed with a blood introduction port 9a, a blood outlet port 9b, a dialysate introduction port 9c, and a dialysate outlet port 9d in its housing, and the blood introduction port 9a has an arterial blood circuit 8a. The proximal end of the venous blood circuit 8b is connected to the blood outlet port 9b. Further, the dialysate introduction port 9c and the dialysate outlet port 9d are connected to the dialysate introduction line L1 and the dialysate discharge line L2 extending from the dialyzer main body 12, respectively.

A plurality of hollow fibers are housed in the dialyzer 9, and the inside of the hollow fibers serves as a blood flow path, and the dialysate flows between the outer peripheral surface of the hollow fibers and the inner peripheral surface of the housing portion. It is said to be a road. A large number of minute holes (pores) penetrating the outer peripheral surface and the inner peripheral surface of the hollow fiber are formed in the hollow fiber to form a hollow fiber membrane, and impurities and the like in blood are introduced into the dialysate through the membrane. It is configured to be transparent to.

On the other hand, as shown in FIG. 3, the dialyzer main body 12 bypasses the double pump P formed across the dialysate introduction line L1 and the dialysate discharge line L2 and the double pump P in the dialysate discharge line L2. It is mainly composed of a connected bypass line L3 and a water removal pump 14 connected to the bypass line L3. Then, by driving the double pump P, the dialysate supplied from the dialysate supply device 13 reaches the dialyzer 9 through the dialysate introduction line L1, and then passes through the dialysate discharge line L2 and the bypass line L3. It is designed to be discharged to the outside of the device.

The water removal pump 14 is for removing water from the patient's blood flowing through the dialyzer 9 to remove water. When the water removal pump 14 is driven, the volume of the liquid discharged from the dialysate discharge line L2 becomes larger than the amount of dialysate introduced from the dialysate introduction line L1, and the amount of water discharged from the blood is increased by the large volume. It will be removed. In addition, instead of the compound pump P, a so-called balancing chamber type may be used.

The hematocrit sensor 15 can detect the concentration (blood concentration) of blood circulating extracorporeally in the blood circuit 8 in a time series in the dialysis treatment process, and includes, for example, a light emitting element such as an LED and a light receiving element such as a photodiode. A hematocrit that indicates the concentration of blood in a patient that flows through the blood circuit 8 and circulates extracorporeally by irradiating blood with light of a predetermined wavelength from a light emitting element and receiving the transmitted or reflected light with a light receiving element. It measures the value. The hematocrit value is an index showing the concentration of blood, and specifically, it is expressed by the volume ratio of red blood cells in the whole blood.

The blood device main body 12 is provided with a blood volume meter 2 as a sensor capable of detecting the rate of change in circulating blood volume (ΔBV) and a sphygmomanometer 3 as a sensor capable of detecting the blood pressure of a patient. The blood volume meter 2 is electrically connected to the hematocrit sensor 15 and can detect the circulating blood volume change rate (ΔBV) based on the hematocrit value (blood concentration) transmitted from the hematocrit sensor 15. Specifically, assuming that the hematocrit value obtained by the hematocrit sensor 15 is Ht, the circulating blood volume change rate ΔBV is (Ht at the start of dialysis-Ht at the time of measurement) / Ht × 100 at the time of measurement. Can be obtained from. As a result, the rate of change in circulating blood volume (ΔBV) of the patient can be detected in real time with the passage of the dialysis treatment time.

In the present embodiment, the rate of change in circulating blood volume (ΔBV) is determined based on the measured hematocrit value, but instead of this, the change in circulating blood volume is based on, for example, hemoglobin concentration or total serum protein concentration. The rate (ΔBV) may be used. Further, in measuring the parameter for obtaining the circulating blood volume change rate (ΔBV), various forms such as optical or ultrasonic waves can be used.

The exercise means S comprises means for the patient to exercise during blood purification treatment (during dialysis treatment in this embodiment), for example, a lower limb ergometer fixed to a bed, a foot pedal fixed to a bed, and strength training. It consists of a dialysis band or a balance ball. If the patient can exercise during the blood purification treatment (during the dialysis treatment in the present embodiment), it is not necessary to equip a specific device or the like, and the exercise may be performed by stretching or gymnastics.

Here, the exercise support device according to the present embodiment includes an input means 4 electrically connected to the blood volume meter 2 and the sphygmomanometer 3, a determination means 5, a notification means 6, and a monitoring means 7. It is composed of. The input means 4 can input a parameter indicating the circulatory dynamics of the patient after the start of the blood purification treatment (hemodialysis treatment). In the present embodiment, the change in the circulating blood volume of the patient measured by the blood volume meter 2 The rate (ΔBV) (parameter related to changes in circulating blood volume) and the patient's blood pressure (parameter related to vital sign) measured by the sphygmomanometer 3 are input.

The determination means 5 determines that the parameter (circulating blood volume change rate (ΔBV) or blood pressure) input by the input means 4 is stable. Specifically, the determination means 5 determines that the parameter input to the input means 4 or the rate of change of the parameter continuously changes within a predetermined range, and determines that the parameter is stable, and the notification means 6 It is possible to notify the exercise start timing with.

For example, when the parameter indicating the circulatory dynamics of the patient input to the input means 4 is the circulating blood volume change rate (ΔBV), the change rate α of the circulating blood volume change rate (ΔBV) continues as shown in FIG. It can be determined that the rate of change in circulating blood volume (ΔBV) is stable, provided that the blood volume has remained within the predetermined range D. On the other hand, as shown in FIG. 5, when the change rate α of the circulating blood volume change rate (ΔBV) does not continuously change within the predetermined range D, it is determined that the circulating blood volume change rate (ΔBV) is not stable. can do.

The notification means 6 can notify the exercise start timing for each individual blood purification treatment according to the patient's condition or the treatment state, and in the present embodiment, the exercise start timing is determined based on the determination by the determination means 5. It is configured to be notified. That is, the notification means 6 notifies that the exercise may be started on the condition that the parameters input by the input means 4 are stable in the determination means 5. The notification means 6 may be in any form such as a display means for displaying the exercise start timing or a notification means for notifying the exercise start timing by voice.

When the determination means 5 determines that the parameter (for example, the rate of change in circulating blood volume (ΔBV)) input by the input means 4 is not stable, the monitoring means 7 monitors the patient's condition or other parameters (for example,). It is for monitoring blood pressure, etc.). As a result, it is possible to monitor changes in the patient's condition when the parameters input by the input means 4 are not stable, and it is possible to ensure safety.

Next, the control contents in this embodiment will be described.
As shown in FIG. 6, first, in S1, it is determined by the determination means 5 whether or not the change rate of the circulating blood volume change rate (ΔBV) is stable. For example, in the case of the transition as shown in FIG. It is determined that the parameter is stable, and the process proceeds to S2 to notify the exercise start timing by the notification means 6. The determination that the parameter according to S1 is stable may be made on the condition that the rate of change in circulating blood volume (ΔBV) is below a preset threshold value.

On the other hand, regarding the rate of change in the circulating blood volume change rate (ΔBV) or the circulating blood volume change rate (ΔBV) in S1, for example, in the case of a transition as shown in FIG. 5, the determination means 5 determines that the parameter is not stable. It is determined that the monitoring means 7 monitors the patient's condition (monitors the patient's condition or monitors other parameters) and does not notify the exercise start timing in S4.

Further, when the parameter indicating the circulatory dynamics of the patient input to the input means 4 is blood pressure, the control as shown in FIG. 7 is performed. In this case, it is determined whether or not the blood pressure (including systolic blood pressure, diastolic blood pressure, mean blood pressure, pulse, etc.) measured by the sphygmomanometer 3 in S1 is lower than the blood pressure measured before the start of treatment, and is lowered. If it is determined that the blood pressure has been reduced, it is determined in S2 whether or not the degree of decrease in blood pressure is within the stable range.

When it is determined in S2 that the degree of decrease in blood pressure is within the stable range, the process proceeds to S3 to notify the exercise start timing by the notification means 6, and in S2, the degree of decrease in blood pressure is within the stable range. If it is determined that the condition is not (for example, a decrease of 100 mmHg or more from the resting state), it is determined that the exercise start timing is not notified in S5. On the other hand, if it is determined that the blood pressure measured by the sphygmomanometer 3 in S1 is not lower than the blood pressure measured before the start of treatment, proceed to S4 and monitor by the monitoring means 7 (monitoring the patient's condition). Alternatively, monitoring of other parameters) is performed, and it is determined that the exercise start timing is not notified in S5.

However, in the present embodiment, among the parameters indicating the circulatory dynamics of the patient input to the input means 4, the circulatory blood volume change rate (ΔBV) is used as a parameter related to the change in the circulating blood volume of the patient, and the vital sign of the patient is used. Although blood pressure is used as a parameter related to, other parameters may be used for each.

Further, in the present embodiment, the input means 4, the determination means 5, the notification means 6, and the monitoring means 7 are arranged outside the hemodialysis device 1, but specific ones or all of these are arranged in the hemodialysis device. It may be arranged inside 1. In that case, the notification means 6 may use the display means, the voice output means, or the like provided in the hemodialysis device 1.

Next, a second embodiment according to the present invention will be described.
Similar to the first embodiment, the exercise support device according to the present embodiment can support the exercise performed by the patient during the blood purification treatment, and as shown in FIG. 8, the exercise means S and the input means 4 A determination means 5, a notification means 6, a monitoring means 7, and a detection means E composed of an electrocardiograph 16, a pulse oximeter 17, a blood flow meter 18, and a body composition meter 19. It is configured. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The detection means E is for detecting parameters related to the vital signs of the patient in the exercise performed during the blood purification treatment. Among them, the electrocardiograph 16 is for detecting the action potential or action current of the myocardium accompanying the beating of the heart. The pulse oximeter 17 is for attaching a probe to a fingertip, an ear, or the like to detect a pulse rate and a percutaneous arterial oxygen saturation (SpO ₂ ). The blood flow meter 18 is for detecting the speed and amount of blood flow. The body composition meter 19 measures various values related to body composition such as body fat, basal metabolic rate, and muscle mass. For example, a weak current is passed through the patient's body to measure electrical resistance to estimate values related to body composition. It is possible.

In the present embodiment, the parameters related to the vital signs of a specific patient obtained by the electrocardiograph 16, the pulse oximeter 17, the blood flow meter 18, or the body composition meter 19 are input means 4 as parameters indicating the patient's hemodynamics. It is possible to notify the exercise start timing by the notification means 6 on condition that the determination means 5 determines that the input parameter is stable.

For example, when the parameter indicating the circulatory dynamics of the patient input to the input means 4 is the heart rate (which may be the respiratory rate), the control as shown in FIG. 9 is performed. In this case, it is determined whether or not the heart rate is stable after the heart rate rises until a certain time elapses in S1, and if it is judged that the heart rate rises and then stabilizes until a certain time elapses, the process proceeds to S2. The notification means 6 notifies the exercise start timing. On the other hand, if it is determined in S1 that the heart rate does not increase until a certain period of time elapses, or after it increases until a certain period of time elapses, it is not stable, the process proceeds to S3.

Then, it is determined that the monitoring means 7 monitors the patient's condition (monitors the patient's condition or monitors other parameters) in S3, and does not notify the exercise start timing in S4. If the heart rate does not increase even after the start of water removal, other parameters may be used in combination to determine the exercise start timing. In addition, when the heart rate rises or falls significantly after a certain period of time, there are obvious ST-T changes (changes indicating myocardial ischemia, etc.), paroxysmal atrial fibrillation, frequent ventricular extrasystole, and RonT-type ventricular phase. When there is external contraction or the appearance of ventricular tachycardia, it is preferable to judge that the exercise start timing is not notified.

Further, for example, when the parameter indicating the circulatory dynamics of the patient input to the input means 4 is oxygen saturation (which may be the pulse wave amplitude considered to reflect the peripheral circulatory state), it is shown in FIG. Such control is performed. In this case, in S1, it is determined whether or not the oxygen saturation is stable after the oxygen saturation has increased until a certain period of time elapses, and if it is determined that the oxygen saturation has increased until a certain period of time has elapsed and then it is stable, the process is set to S2. The notification means 6 is willing to notify the exercise start timing.

On the other hand, if it is determined in S1 that the oxygen saturation does not increase until a certain time elapses, or the oxygen saturation increases until a certain time elapses, and then it is not stable, the process proceeds to S3. Then, it is determined that the monitoring means 7 monitors the patient's condition (monitors the patient's condition or monitors other parameters) in S3, and does not notify the exercise start timing in S4. Since the pulse wave amplitude tends to decrease by removing water, the exercise start timing may be notified when the pulse wave amplitude falls below a certain value.

Next, a third embodiment according to the present invention will be described.
The exercise support device according to the present embodiment can support the exercise performed by the patient during the blood purification treatment as in the first and second embodiments, and as shown in FIG. 11, the exercise means S and the input It has means 4, a determination means 5, a notification means 6, and a monitoring means 7, and the input means 4 is electrically connected to a dialysis amount monitor 20 arranged in the hemodialysis apparatus 1. ing. The same components as those in the first and second embodiments are designated by the same reference numerals, and detailed description thereof will be omitted.

The dialysate monitor 20 is arranged on the dialysate discharge line L2 (see FIG. 3) in the dialysis apparatus main body 12, and the concentration of the drainage from the dialyzer 9 discharged with the blood purification treatment (for example, in the drainage). By detecting the urea concentration), Kt / V (standardized dialysis dose) can be monitored. Kt / V is calculated by the following calculation formula.

Standardized dialysis dose (Kt / V) = -ln (C (e) / C (s) -0.008t) + (4-3.5 × C (e) / C (s)) × (V _UF / DW) )
However, C (s) is the urea nitrogen concentration (initial value) at the start of hemodialysis treatment, C (e) is the urea nitrogen concentration at the present time (at the time of monitoring), _VUF is the amount of water removed, DW is the patient's dry weight, and K. Is the clearance, t is the elapsed time of dialysis treatment, and V is the urea distribution volume.

In the present embodiment, the drainage concentration obtained by the dialysate monitor 20 can be input to the input means 4 as a parameter indicating the state of treatment, and the determination means 5 determines that the input parameter is stable. The exercise start timing can be notified by the notification means 6 on condition that the determination is made. For example, as shown in FIG. 12, the drainage concentration measured by the dialysate monitor 20 continuously changes within the predetermined range D (in particular, in the present embodiment, the predetermined range is between the time T1 and the time T2). (Transition within D), the determination means 5 determines that the parameter is stable, and as shown in FIG. 13, the drainage concentration does not continuously change within the predetermined range D (particularly in the present embodiment). Does not change within a predetermined range between the time T1 and the time T2), the determination means 5 determines that the parameter is not stable.

According to the above embodiment, since the notification means 6 capable of notifying the exercise start timing for each blood purification treatment according to the patient's condition or the treatment condition is provided, blood is provided according to the patient's condition or the treatment condition. Exercise during purification treatment can be started at the right time. In particular, according to the first and second embodiments, the input means 4 capable of inputting the parameters indicating the circulatory dynamics of the patient after the start of the blood purification treatment and the parameters input by the input means 4 are stable. Since the notification means 6 can notify the exercise start timing based on the judgment by the determination means 5, the exercise can be started at a more appropriate timing.

Further, the determination means 5 according to the present embodiment determines that the parameter is stable on the condition that the parameter input to the input means 4 or the rate of change of the parameter continuously changes within a predetermined range, and notifies the determination means. Since the exercise start timing can be notified by the means 6, the exercise start timing can be accurately notified. Further, the parameters input to the input means 4 are parameters related to changes in the circulating blood volume of the patient (rate of change in circulating blood volume (ΔBV), etc.), parameters related to the vital signs of the patient (blood pressure, etc.), or blood purification treatment. Since it consists of parameters related to (drainage concentration, etc.), it is possible to more accurately notify the exercise start timing.

Furthermore, according to the first embodiment and the third embodiment, the parameters input to the input means 4 are sensors (blood volume meter 2, blood pressure) provided in the blood purification device for performing blood purification treatment. Since it is detected by a total of 3, dialysate monitor 20 and the like), it is possible to use a sensor for treatment to notify the exercise start timing. Further, according to the second embodiment, since the detection means E for detecting the parameters related to the vital signs of the patient is provided, it is possible to more accurately grasp the patient's condition when notifying the exercise start timing. it can.

The exercise support device according to the present embodiment has been described above, but the present invention is not limited to this. For example, in the first embodiment, the circulating blood volume is a parameter related to the change in the circulating blood volume of the patient. The rate of change is used, but instead or in conjunction with this, a plasma refilling rate (PRR) that is continuously measurable during blood purification treatment may be used. The plasma refilling rate (PRR) can be calculated by the following calculation formula using the blood volume meter 2 of the hemodialysis apparatus 1. However, it is calculated on the assumption that the circulating blood volume of the patient is 1/13 of the body weight before the treatment.

PRR = (water removal amount in measurement section + hypervolemia in measurement section) / time in measurement section Hypervolemia in measurement section = circulation blood volume x rate of change in ΔBV in measurement section Circulation blood volume = weight before treatment / 13

When this plasma refilling rate (PRR) is input to the input means 4 as a parameter related to the change in the circulating blood of the patient, it is determined by the determination means 5 that the input plasma refilling rate (PRR) is stable. On condition that this is the case, the notification means 6 notifies the exercise start timing.

Furthermore, as a condition for notifying the exercise start timing by the notification means 6, it is sufficient if the patient's condition or the treatment condition satisfies a predetermined condition, for example, an image of the patient's state taken by a camera or a thermometer is used for measurement. It may be a condition that the body temperature of the patient and the amount of sweating of the patient measured by the sensor satisfy the predetermined conditions. Although this embodiment is applied to the hemodialysis device 1 that performs hemodialysis treatment, it may be applied to another blood purification device that performs blood purification treatment.

If it is an exercise support device equipped with a notification means capable of notifying the exercise start timing for each blood purification treatment according to the patient's condition or the treatment condition, it should be applied to those with other functions added. Can be done.
