Detailed Description of the Invention

[0001]

The present invention relates to relates to setting apparatus water removal speed of patients in hemodialysis.

[0002]

2. Description of the Related Art Conventionally, in order to perform dialysis, the total amount of water removed during the dialysis time for each patient and the type of waste products to be removed are determined in advance according to the patient's condition before dialysis and removed from the blood. A dialysate is prepared according to the type of waste, the concentration thereof is determined, and the water removal rate at each time of the dialysis time is determined according to the total amount of water removed.

However, since the patient's symptom and weight change daily, it is not possible to directly use the target water removal amount at the previous dialysis, the dialysis time, etc., and it is necessary to flexibly change according to the situation of the day. Occurs. Therefore, the water removal rate and the like are not always constant even during the dialysis time, and it is necessary to change in accordance with the patient's symptoms every dialysis time.

Therefore, conventionally, there have been considered and used many methods and apparatuses for setting a water removal program, which can arbitrarily set the water removal rate and the like. JP-A-7
Japanese Unexamined Patent Publication (Kokai) No. 132141 discloses a method and a device capable of easily setting a water removal rate or the like for each patient.

[0005]

However, in the conventional method of setting the water removal rate and the like, the water removal pattern is set in advance and the pattern itself is stretched without changing the shape of the water removal pattern. The method of adjusting by compression was the mainstream. Therefore, it is necessary to select an appropriate water removal pattern from the water removal patterns set in advance for each patient.Therefore, it is possible to freely set the water removal rate, etc. according to the patient's symptoms. could not.

Further, although the water removal pattern can be expanded / compressed according to the dialysis time, the pattern shape itself does not change, so the degree of freedom in setting is small, and the fine setting can be made according to the patient's symptoms. I couldn't. Furthermore, since the water removal pattern itself is enlarged / reduced to set the water removal speed, etc., the water removal conditions are set until the water removal treatment for one pattern is completed, that is, while the water removal treatment is being performed. Etc. could not be changed.

For example, in the conventional method of setting the water removal speed, etc., since each step is recognized as a block of a constant time unit, only a predetermined step is expanded in time.
Could not be compressed. Specifically, if you want to incorporate a short time unit step into a standard step that is divided by a fixed time unit, just to incorporate this step, a large number of standard steps that originally do not require setting changes It was necessary to change the setting as a short time unit step. On the contrary, if you want to incorporate long time unit steps, all steps will be changed in the long time unit, so set only a coarser pattern than the water removal pattern set in the standard step. Since it cannot be performed, there is an inconvenience that fine adjustment cannot be performed.

On the other hand, since it is necessary to carefully select a pattern, there are many input items for conditions necessary for selecting a water removal pattern such as a symptom of a patient, and work for inputting initial conditions is complicated. For example, setting various conditions necessary for performing dialysis such as water removal rate for all conditions from one to all requires time and labor for the operator, which is an obstacle to promptly performing the operation.

The present invention eliminates the above-mentioned adverse effects and introduces the concept of the time axis, so that an appropriate water removal rate according to the symptom of a patient can be obtained without being restricted by a preset water removal pattern . and to provide a setting apparatus for water removal program having a user interface that can perform conditions set and change easily.

[0010]

Means for Solving the Problems] setting TeiSo location of water removal program according to the present invention in order to solve the above problems, an input means for a dewatering amount of a target entering the dialysis time, the dialysis input An initial water removal pattern forming means for forming an initial water removal pattern consisting of a plurality of steps set to a constant water removal rate obtained by dividing the target water removal amount by the dialysis time at dialysis time intervals equally divided into times. And a means for forming a second water removal pattern by changing the water removal rate and the dialysis time interval for each step of the initial water removal pattern.

With this configuration, it is possible to set an appropriate water removal rate according to the dialysis time without being restricted by the set water removal pattern, and to make fine settings according to the patient's symptoms. Is possible.

Further, in the programmed water removal setting method and apparatus according to the present invention, it is preferable that the steps evenly divided into fixed time intervals can be added to the second water removal pattern. At the same time, it is preferable that the program water removal setting method and apparatus according to the present invention can delete the steps evenly divided into a predetermined time interval from the second water removal pattern. This is because it is possible to flexibly change the water removal program such as adding a step of removing water at a certain water removal rate or omitting the next step according to the patient's symptoms.

Next, the programmed water removal setting method and apparatus according to the present invention has an input means for inputting a target water removal amount and dialysis time in setting a water removal program in hemodialysis. It is characterized by setting the temporal change of the water removal rate from.

With this configuration, it is possible to set an appropriate water removal rate according to the dialysis time without being restricted by the set water removal pattern, and to make fine settings according to the patient's symptoms. Is possible.

Further, according to the program water removal setting method of the present invention, during the hemodialysis, the water removal rate and the dialysis time interval in the area of the second water removal pattern which has not been removed yet. Is preferably changed.

With this configuration, it is possible to change the water removal pattern during dialysis, which could not be changed conventionally, and it is appropriate to dynamically change the water removal rate even for sudden changes in the patient's symptoms. It is possible to take various measures.

[0017]

[0018]

Further, the programmed water removal setting apparatus according to the present invention is such that, while performing hemodialysis, the water removal rate and the dialysis time interval in the area of the second water removal pattern where water has not been removed yet. Is preferably changeable.

With such a configuration, the water removal pattern during dialysis, which could not be changed conventionally, can be changed, and it is appropriate to dynamically change the water removal rate even when the patient's symptoms suddenly change. It is possible to take various measures.

Further, the programmed water removal setting apparatus according to the present invention can visually confirm the relationship between the water removal rate and the dialysis time interval, and the value can be displayed on the screen without directly inputting the value from a keyboard or other input medium. It is preferable to have a user interface capable of inputting an appropriate value through a visually recognizable change operation.

With this structure, various conditions can be easily set in the conventional water removal program setting work, and the water removal program can be set in a relatively short time.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method and apparatus for setting a water removal program according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

FIG. 1 is an explanatory diagram of a conventional water removal program setting method. As shown in FIG. 1, the water removal pattern has a water removal rate determined for each uniform unit time, and has a step-like shape as shown in (a) to (e). At the time of use, a water removal pattern that is considered to be most suitable for the present patient's symptoms is selected from these preset water removal patterns and executed.

FIG. 2 is an explanatory diagram of a method of changing a water removal pattern in a water removal program in a conventional water removal program setting device. As shown in FIG. 2, for example, assuming that the water removal pattern (c) is selected from the water removal patterns prepared in advance as the initial water removal pattern in FIG. 1, the water removal pattern is the optimum water removal pattern for the patient. To make it compatible, use the following method. That is, in FIG. 2, even if the optimum water removal pattern is selected from the initial input data such as the symptom of the patient, that alone does not correspond to the actual dialysis time. Therefore, as shown in (a), the water removal pattern is extended in the time direction, or as shown in (b), the water removal pattern is compressed in the time direction, thereby performing adjustment in proportion to the actual dialysis time. The expansion / compression of the water removal pattern is carried out by expanding / compressing the uniform water removal pattern as a whole at a constant magnification.

FIG. 3 is an explanatory view of the concept of setting the amount of water removed in the program water removal setting method according to the embodiment of the present invention. In FIG. 3, the initial water removal pattern is set by setting the water removal amount for each step. The reason for setting an arbitrary time from the time of initial setting is that it is rather complicated in terms of processing.

The difference from the conventional setting method is that the steps are not divided into unit time units which are even, but an arbitrary water removal time period can be set for each step. For example, it is possible to set a fine pattern such that water is removed at 3 (l / hr) for the first 5 minutes, but water is removed at 7 (l / hr) for the next 30 minutes. This is possible by introducing the concept of a time axis whose origin is the dialysis start time in setting the time. That is, starting from the origin, the water removal amount calculated from the water removal rate at each step is accumulated until the target water removal amount is reached, and the water removal of the target water removal amount is completed within the target dialysis time in each step. The water removal rate and the dialysis time interval for each step are set.

Further, arbitrary steps can be added / inserted in the already set water removal pattern.
For example, it is possible to add / insert a step of removing water at 5 (l / hr) for 30 minutes between the second step and the third step. On the contrary, an arbitrary step can be deleted from the already set water removal patterns. For example, 20 that was set as the fifth step
It is also possible to delete the step of removing water at 8 (l / hr) per minute from the water removal pattern as it is.

How to set the actual water removal rate through the user interface will be described with reference to FIGS. 4 to 8. FIG. 4 is a conceptual diagram of an initial setting interface of the water removal program setting device according to the embodiment of the present invention.

In FIG. 4, the target water removal amount and the dialysis time are set as digital values by the button switches 401 to 404. Using the value set here, fine adjustment is performed in the detailed setting interface.

FIG. 5 is an explanatory view of a step selection procedure to be changed in the screen interface in the water removal program setting device according to the embodiment of the present invention.
In FIG. 5, the step selection buttons 501 indicated by “<<” and “>>” are used to select the step for which the water removal speed or the like is to be changed. In the example of FIG. 5, the second hatched step is selected.

FIG. 6 is an explanatory diagram of a procedure for changing the water removal rate in the screen interface of the apparatus for setting the water removal program according to the embodiment of the present invention. In FIG. 6, the water removal speed change button 601 can be used to arbitrarily change the water removal speed. In the example of FIG. 6, the water removal rate is increased in the second hatched step. In this case, the total amount of water removed will be greater than the initially entered set value, so it is necessary to reduce the water removal rate in other steps by displaying the changed total amount of water removed on the screen. Try to suggest that.

FIG. 7 is an explanatory diagram of a dialysis time changing procedure for performing water removal at the water removal rate in the screen interface in the water removal program setting device according to the embodiment of the present invention. In FIG. 7, the dialysis time interval change button 7
01 can be used to change the dialysis time interval arbitrarily. In the example of FIG. 7, the dialysis time interval is increased in the second hatched step. In this case as well, by displaying the changed total water removal amount on the screen as in the case of increasing the water removal rate, it is suggested that the dialysis time interval should be decreased in the operation of other steps. To

By repeating the above-mentioned method, the water removal rate and the like can be finely set according to the symptoms of the patient. In addition, since it is possible to visually check the increase / decrease of the water removal rate and the increase / decrease of the dialysis time interval, it is useful for preventing input errors.

FIG. 8 is an explanatory diagram of a process for changing the water removal rate or the like during dialysis in the screen interface of the water removal program setting device according to the embodiment of the present invention. In FIG. 8, a hatched area indicates a portion where water removal has been completed up to the present. This area cannot be changed because it has already been drained. For the remaining non-hatched areas, the water removal rate and the dialysis time interval can be changed by repeating the procedure of FIGS. 5 to 7 as in the case of performing the initial setting. By being able to change the water removal rate, etc. even during dialysis, it is possible to respond immediately to sudden changes in the patient's symptoms, etc., and effective medical activities can be expected.

FIG. 9 is an explanatory diagram of a process for adding or deleting an arbitrary step to the set water removal pattern in the screen interface in the water removal program setting device according to the embodiment of the present invention. .
In FIG. 9, the step immediately before the point where the water removal step is desired to be added is selected using the step selection button 501.

In FIG. 9, the third step from the left has been selected so as to insert a new step after the third step from the left with hatching, that is, between the third and fourth steps from the left. Indicates. Here, when the step insertion button 901 is pressed, the fourth step is newly inserted and the new step is selected. Subsequent work procedures are similar to those in FIGS. 5 to 8, and the water removal speed and the like are set for the newly added steps.

On the other hand, if you want to delete the water removal step,
Similar to the case of adding, the step selecting button 501 is used to select the step to be deleted. For example, in FIG. 9, the third step from the left is selected as the deletion target step, so if the step deletion button 902 is pressed here, the step is deleted.

As described above, according to the present embodiment, by introducing the concept of the time axis, the degree of freedom in setting the water removal rate and the dialysis time interval is dramatically increased, and it is possible to adapt to the symptoms of the patient on that day. Not only allows you to perform hemodialysis
Even when the patient's symptom suddenly changes during dialysis, it is possible to take appropriate measures by changing the dialysis rate and the like.

Further, according to the present embodiment, since the user interface capable of visually grasping the relationship between the water removal rate in hemodialysis and the dialysis time interval is provided, it is useful for preventing human error. It is possible to reduce the labor of the operator.

[0041]

According to the water removal program set TeiSo location according to the present invention as described above, according to the present invention, the water removal time, etc. set for hemodialysis, it is possible to create a free water removal pattern, patient symptoms It is possible to set fine-tuned conditions according to.

[0042] In addition, the water removal program set according to the present invention
According to equipment, when the symptoms of the patient in the middle of the dialysis is suddenly changed, it becomes possible to cope immediately by appropriate modification of the water removal speed.

Further, in the water removal program setting device according to the present invention, since the user interface for easily setting / changing the water removal speed and the like is provided, the labor of the operator is reduced and the detailed operation is possible. The conditions can be easily set, and an optimal water removal pattern can be created according to the patient's symptoms.
