JP 2011-87678 A

  An operator such as a medical worker who operates such a medical device such as an infusion pump operates a dial or the like relatively slowly when selecting an item to be set as described above. If you have to set up medical devices such as infusion pumps for multiple patients, you have to operate the dial etc. quickly to finish the setting of numerical values etc. quickly. There was a problem that it was difficult to operate.

  Accordingly, an object of the present invention is to provide a medical device that facilitates setting of a medical device such as an infusion pump and a method for controlling the medical device.

  In the present invention, the above object includes a display unit that displays information, and a display information change unit that can change display information that is information displayed on the display unit. Is configured to be changed and displayed based on the movement of the display information changing unit, and the changing speed of the display information is different depending on the type of the display information. Achieved by equipment.

According to the above configuration, the display information is configured to be changed and displayed based on the movement of the display information changing unit, and the change speed of the display information is different depending on the type of the display information. .
For this reason, for example, when the type of display information is a numerical value change screen with a large number of digits, it is necessary to perform the operation of the display information change unit for a long time for the change. In the case of a screen, it is not necessary to perform the operation of the display information changing unit for a long time for switching the item.

Therefore, in such a case, the numerical value change screen is configured so that the display information changing unit can set the display information changing speed faster than the item selection screen, and the numerical value change can be executed quickly.
On the other hand, the item selection screen has a configuration in which the display information changing unit changes the display information as usual, and the change speed is not too fast for the operator and is easy to operate.
Therefore, in the present invention, the operator can easily set the medical device.

  Preferably, the display information includes individual display information having a plurality of different contents, and a display information group is formed by an aggregate of the plurality of individual display information, and the display information is the individual display information. The individual display information of the display information group and the individual detail display information are changed and displayed based on the movement of the display information changing unit. The change rate of the individual display information that is changed and displayed based on the movement of the display information changing unit is different from the change rate of the detailed individual display information.

According to the configuration, the display information group includes the individual display information, and the individual display information is associated with the detailed individual information. In addition, the change speed of the individual display information that is changed and displayed based on the movement of the display information changing unit is different from the change speed of the detailed individual display information.
Therefore, for example, when the detailed individual display information has a numerical value change screen with a large number of digits and the change takes time, the individual display information has, for example, an item selection screen for setting information of the medical device. However, when it takes no time to select the screen, the change time of the detailed individual display information is made longer than the change time of the individual display information, so that the operator can operate quickly.

  Preferably, when the change speed of the display information changed and displayed based on the movement of the display information change unit is equal to or higher than a predetermined speed, the change speed of the display information exceeds the predetermined speed depending on the type of the display information. Alternatively, the speed is changed to less than the predetermined speed.

According to the above configuration, when the change speed of the display information that is changed and displayed based on the movement of the display information change unit is equal to or higher than a predetermined speed, that is, the movement of the display information change unit that is an operation of the display information change unit by the operator When is equal to or higher than a predetermined speed, the speed is adjusted according to the type of display information.
For example, when the type of display information is an item selection screen for setting information of medical equipment and the screen selection does not require quick screen switching, display information that is changed and displayed based on the movement of the display information changing unit When the change speed is equal to or higher than the predetermined speed, the change speed is changed to less than the predetermined speed.
Accordingly, the operator can avoid a situation in which the operation of the display information changing unit is too fast, and thus the change of the display screen is too fast and difficult to operate.

On the other hand, for example, when the display type information is a numerical value change screen with a large number of digits, it is necessary to perform the operation of the display information change unit for a long time for the change. If the change speed of the display information that is changed and displayed based on the movement of the display information changing unit is equal to or higher than the predetermined speed, the change speed is changed to be higher than the predetermined speed.
As a result, it is possible to quickly and efficiently perform a change such as a numerical change with a large number of digits that takes time to operate.
Thus, in the said structure, when the change speed of the display information changed and displayed based on the motion of a display information change part is more than predetermined speed, the change is carried out by the display information which is the object changed by a display information change part. By changing the speed, the medical device is easy to operate for the operator.

Preferably, a selection screen transition unit that selects a specific individual display information screen from a plurality of individual display information screens of the plurality of individual display information displayed on the screen of the display unit and transitions to a selected setting screen, A change screen transition unit that transitions the individual display information screen selected on the selected setting screen to the changeable setting screen of the detailed individual display information, and
In the individual display information screen, the selected setting screen, and the changeable setting screen, at least background colors are different.

  According to the above configuration, since the background color is different at least in the individual display information screen, the selected setting screen, and the changeable setting screen, the operator can simply view the current screen by simply viewing the display unit. However, it can be easily determined whether it is an individual display information screen, a selected setting screen, or a changeable setting screen.

  In the present invention, the above-described object is a method for controlling a medical device, which includes a display unit that displays information and a display information change unit that can change display information that is information displayed on the display unit. The display information is configured to be changed and displayed based on the movement of the display information changing unit, and the change speed of the display information differs depending on the type of the display information. This is achieved by a method for controlling a medical device.

  As described above, according to the present invention, it is possible to provide a medical device that facilitates setting of a medical device such as an infusion pump and a method for controlling the medical device.

However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

FIG. 1 is a schematic diagram showing an external appearance of, for example, an infusion pump 10 that is a medical device. The infusion pump 10 has a configuration in which a tube or the like for feeding a chemical solution can be disposed therein, and by performing an operation such as squeezing on the tube, the liquid solution to be fed in the tube The flow rate is controlled.
Moreover, as shown in FIG. 1, the infusion pump 10 has an infusion pump display 20 made of, for example, a color liquid crystal that is a display unit, and can display various information such as the flow rate of the medicinal solution. .

  The information displayed on the infusion pump display 20 is individual display information, for example, “flow rate display information” for controlling the amount of the medicinal solution to be administered to the patient, and the planned amount and the scheduled time of the medicinal solution to be administered to the patient. “Scheduled amount / scheduled time display information”, “integrated amount display information” for controlling the accumulated amount of the medicinal solution to be administered to the patient, and the like. These pieces of information are extremely important information when a drug solution is administered to a patient, and information that cannot be mistaken. Aggregates such as “flow rate display information”, “scheduled amount / scheduled time display information”, and “integrated amount display information” are examples of the display information group (display information).

As shown in FIG. 1, the infusion pump 10 includes a display change dial 11 formed of, for example, a jog dial, which is a display information change unit that rotates (rotates) in both forward and reverse directions along the direction of the arrow R1. ing.
That is, by rotating the display change dial 11, for example, any one of “flow rate display information”, “scheduled amount / scheduled time display information”, and “integrated amount display information” is arbitrarily displayed on the infusion pump display 20, It is configured to be able to select and transition to a selected screen (an example of a “selected setting screen”).

As shown in FIG. 1, the infusion pump 10 has an OK button 12 and “flow rate display information”, “scheduled amount / scheduled time display information”, “integrated amount display information” selected by the display change dial 11 described above. When the OK button 12 is pressed on any of the selected screens such as “”, the screen changes to a changeable setting screen, for example, a change setting screen of detailed individual labeling information that changes data about the selected display screen. It has a possible configuration.
Thus, the information displayed on the changeable screen is an example of “detailed individual display information”.
The changeable screen is configured such that, for example, a number or the like, which is the detailed individual display information, can be changed by rotating the display change dial 11.
In addition, the infusion pump 10 also includes a power switch 18.
These configurations will be described later in detail.

As shown in FIG. 1, the infusion pump 10 is also provided with other input devices 13 and the like, and is configured to be able to input other information.
Further, the infusion pump 10 shown in FIG. 1 has a computer, and the computer has a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., which are not shown. Connected through.

FIG. 2 is a schematic block diagram showing the main configuration of the infusion pump 10 shown in FIG.
As shown in FIG. 2, the infusion pump 10 has an infusion pump control unit 14 that controls and judges the operation of the entire infusion pump 10. The infusion pump control unit 14 controls the “infusion pump main body 15” responsible for the basic operation of the infusion pump 10, and the above-mentioned “infusion pump display 20” “display change dial 11” “OK key 12”. , “Other input device 13” and “power switch 18” are controlled. Further, the “timer device 17” shown in FIG. 2 and the “dial rotation speed detection device 19” that detects the rotation speed of the dial when the operator operates the “display change dial 11” are also controlled. ing.
The infusion pump control unit 14 is also configured to control the “various processing unit (program) storage unit 30”, various data storage units, and the like related to the infusion pump 10 shown in FIG. Will be described later.
FIG. 3 is a schematic block diagram showing the configuration of various processing units (programs) storage unit 30.

  FIG.4 and FIG.6 is a schematic flowchart which shows the operation example of the infusion pump 10 which concerns on this Embodiment. In the following, according to the schematic flowcharts of FIGS. 4 and 6, the operation and the like will be described, and the configurations of FIGS.

First, in ST1 of FIG. 4, the “power switch 18” of FIGS. 1 and 2 is turned on.
Next, the process proceeds to ST2. In ST2, it is determined whether an operator such as a medical worker has rotated the display change dial 11 of the infusion pump 10 in FIG. 1 in the direction of arrow R in FIG.
Specifically, the “dial rotation speed detection device 19” in FIG.

If it is determined in ST2 that the display change dial 11 has started the rotation operation, the process proceeds to ST3. In ST3, the “dial rotation speed detection device 19” of FIG. 2 acquires dial rotation speed data of the display change dial 11 of FIG. 1 and the like, and stores it in the “dial rotation speed data storage unit 21” of FIG. To do.
Specifically, when the display change dial 11 moves in the direction of arrow R in FIG. 1 by a predetermined amount of rotation, a signal of “1 pulse” is output. And it is the structure which detects the rotational speed by the frequency | count that this pulse was output within predetermined time.

Next, the process proceeds to ST4. In ST4, it is determined whether or not the “dial rotation speed data” stored in the “dial rotation speed data storage unit 21” in FIG. 2 is “normal speed”.
Specifically, the “dial rotation speed determination processing unit (program) 31” in FIG. 3 operates, and “dial rotation speed data” and “ordinary rotation reference speed data storage unit 22” in FIG. Judgment by comparing with “speed data”.
For example, in the present embodiment, as “normal speed data”, as shown in FIG. 2, data of a predetermined value (for example, “the number of pulses by dial rotation for 50 ms (milliseconds) is 2 or less”) is previously stored. It is remembered.
Therefore, in ST4, it is determined whether or not “dial rotation speed data” is equal to or less than a predetermined value (for example, “the number of pulses due to dial rotation for 50 ms (milliseconds) is 2 or less”).

If it is determined in ST4 that the “dial rotation speed data” is “the number of pulses by dial rotation for 50 ms (milliseconds) is 2 or less”, that is, “normal speed”, the process proceeds to ST5.
In ST5, the infusion pump 10 is in the “normal rotation speed mode (the rotation of the display change dial 11 is counted as one pulse (one screen))” in the “dial rotation reference speed data storage unit 22” of FIG. Data is acquired, and in this mode, the screen of each item information of “flow rate display information”, “scheduled amount / scheduled time display information”, and “integrated amount display information” is controlled to be displayed in order on the infusion pump display 20.

That is, the screen is changed (changed) every time the display change dial 11 is rotated by one pulse.
The screen data of each item is stored in the “infusion pump display display data storage unit 23” in FIG. 2, and is displayed on the infusion pump display 20 with reference to this data.
Specifically, the “dial corresponding screen display unit (program) 32” in FIG. 3 executes.
Accordingly, the screen of each item information such as “flow rate display information” is sequentially displayed on the infusion pump display 20 almost in synchronization with the speed at which the operator rotates the display change dial 11.

On the other hand, if “dial rotation speed data” is not less than or equal to a predetermined value (eg, “the number of pulses due to dial rotation for 50 ms (milliseconds) is 2 or less”) in ST4, the process proceeds to ST6.
In ST6, the infusion pump 10 acquires “speed data for item selection instead of normal speed”, that is, “low-speed rotation mode” data in the “dial rotation reference speed data storage unit 22” in FIG. In the present embodiment, for example, the rotation of the display change dial 11 is 10 pulses and one count (one screen) is in the “low-speed rotation mode”.

Therefore, in the case of ST6, when the operator turns the display change dial 11, the infusion pump display 20 displays each of the “flow display information” and the like at a speed of “1 count per 10 pulses (one screen)”. The item information screens are sequentially displayed on the infusion pump display 20.
As described above, in the present embodiment, when the operator turns the display change dial 11 faster than necessary, the screen of each item information such as “flow rate display information” changes in a similar manner in synchronization with it. Then, when it becomes difficult to visually recognize the information on the screen, the screen transition speed can be adjusted to automatically adjust the speed to be easily visible to the operator.

Next, the process proceeds to ST7. In ST7, it is determined whether or not the operator has selected item information such as specific “flow rate display information” in ST5 or ST6.
Specifically, the operator operates the display change dial 11 and the OK key 12 in FIG. 1 to display a screen such as “flow rate display” on the “infusion pump display 20” in FIG. Select (selected screen).
Specifically, the selection of this screen is executed by the “display type determination processing unit (program) 33” in FIG. Therefore, the “display type determination processing unit (program) 33” is an example of the selection screen transition unit.

  When the selection is completed in ST7, for example, when the screen is selected to display the “flow rate display” screen on the “infusion pump display 20” in the above-described example, the process proceeds to ST8.

In ST8, in order to indicate that the selected screen is in a selected state, for example, the background color is changed from normal “light blue” to “light blue”.
Specifically, the “infusion pump display light blue display processing unit (program) 34” in FIG. 3 executes.

FIG. 7 is a schematic explanatory diagram showing a state where the background display of the “infusion pump display 20” has changed to “light blue”. In FIG. 7, diagonal hatching from upper right to lower left indicates a light blue part.
Thus, by setting the background of the screen of the “infusion pump display 20” to “light blue”, the operator who is a medical worker of the infusion pump 10 can visually recognize the “infusion pump display 20”. It is possible to immediately and easily grasp that the screen is in the “selected screen” state.

Next, the process proceeds to ST9. In ST9, it is determined whether or not a signal for changing the numerical value of the flow rate shown in FIG. 7 to a changeable state is input from the operator or the like in the state selected in the “flow rate display” screen in ST7.
Specifically, it is determined whether or not the operator has pressed the “OK button 12” in FIG. 1. When it is determined that the “OK button 12” has been pressed, the screen is changed to a changeable screen. .
Specifically, the “changeable screen change determination processing unit (program) 35” makes a determination, and the “changeable screen change determination processing unit (program) 35” is an example of a change screen transition unit.

Next, the process proceeds to ST10. In ST10, in order to indicate that the “infusion pump display 20” has transitioned to the “changeable screen”, for example, the background color is changed from “light blue” to “dark light blue”.
Specifically, the “infusion pump display dark light blue display processing unit (program) 36” in FIG. 3 executes.

FIG. 8 is a schematic explanatory view showing a state in which the background display of the “infusion pump display 20” is changed to “dark blue”. In FIG. 8, diagonal hatching from the upper left to the lower right indicates a dark light blue part.
Thus, by setting the background of the screen of “infusion pump display 20” to “dark blue”, an operator who is a medical worker of the infusion pump 10 visually recognizes the “infusion pump display 20”, It is possible to immediately and easily grasp that the current state is the “changeable screen”.

  Next, the process proceeds to ST11. In ST11, when the “changeable screen” as shown in FIG. 8 displayed on the “infusion pump display 20” has a plurality of changeable parts, for example, the numerical value “300.00” in FIG. If there are 5 numbers (3 digits up to 100 and 5 digits after the decimal point), the number with the most digits, for example, the “3” part of the 100s For example, it is underlined to indicate that the number “3” can be changed.

FIG. 9 is a schematic explanatory diagram showing a state in which the “infusion pump display 20” has transitioned to the “changeable screen” and the changeable part is underlined.
As shown in FIG. 9, among the numerical value “300.00” displayed on the “infusion pump display 20”, the changeable part “3” in the hundreds position is underlined and the relevant part can be changed. It is shown that. Note that highlight display may be used instead of underline display.
Specifically, the changeable part display processing unit (program) 37 "of FIG. 3 executes.

  Therefore, the operator can clearly identify the number related to the current change simply by visually recognizing the “infusion pump display 20”, and the infusion pump 10 is easy to operate.

  In this state, the operator can change the underlined number “3” by operating the display change dial 11 of FIG. 1. Further, the change is confirmed by pressing the OK key 12 in FIG.

  Next, the process proceeds to ST12. In ST12, as in ST2 described above, it is determined whether an operator such as a medical worker has rotated the display change dial 11 of the infusion pump 10 in FIG. 1 in the direction of arrow R in FIG.

  If the display change dial 11 determines in ST12 that the rotation operation has started, the process proceeds to ST13. In ST13, the dial rotation speed data of the display change dial 11 in FIG. 1 or the like is acquired by the “dial rotation speed detection device 19” in FIG. 2 and the “dial rotation speed in FIG. The data is stored in the data storage unit 21 ”.

Next, the process proceeds to ST14. In ST14, as in ST4 described above, it is determined whether or not the “dial rotation speed data” stored in the “dial rotation speed data storage unit 21” in FIG. 2 is “normal speed”.
Specifically, the determination is made by comparing the “dial rotation speed data” with the “normal speed data” in the “dial rotation reference speed data storage unit 22” in FIG.
As described above, in the present embodiment, as “normal speed data”, as shown in FIG. 2, data “the number of pulses by dial rotation for 50 ms (milliseconds) is 2 or less” is stored in advance. Yes.
Therefore, in ST14, it is determined whether or not the “dial rotation speed data” is “the number of pulses by dial rotation for 50 ms (milliseconds) is 2 or less”.

  If it is determined in ST14 that the “dial rotation speed data” is “the number of pulses by dial rotation for 50 ms (milliseconds) is 2 or less”, that is, “normal speed”, the process proceeds to ST15.

In ST5, the infusion pump 10 is in the “normal rotation speed mode (the rotation of the display change dial 11 is counted as one pulse (one screen))” in the “dial rotation reference speed data storage unit 22” of FIG. Data is acquired, and control is performed to sequentially display “numbers” on the infusion pump display 20 in this mode.
The screen data of each item is stored in the “infusion pump display display data storage unit 23” in FIG. 2, and is displayed on the infusion pump display 20 with reference to this data.
Specifically, the “dial corresponding screen display unit (program) 32” in FIG. 3 executes.
Therefore, the underlined number “3” can be changed almost in synchronization with the speed at which the operator rotates the display change dial 11.

On the other hand, if “dial rotation speed data” is not “the number of pulses due to dial rotation for 50 ms (milliseconds) is 2 or less” in ST14, the process proceeds to ST16.
In ST16, the infusion pump 10 acquires “speed data of numerical input, not“ normal speed ”, that is,“ high-speed rotation mode ”data in the“ dial rotation reference speed data storage unit 22 ”of FIG.
In the present embodiment, for example, the rotation of the display change dial 11 is 10 counts per pulse (10 screens) is the “high-speed rotation mode”.
Therefore, in the case of ST16, when the operator turns the display change dial 11, the “number” screen is sequentially displayed on the infusion pump display 20 at a speed of “10 counts per pulse (one screen)”. It will be displayed on the pump display 20.

  As described above, in this embodiment, when the operator turns the display change dial 11 faster than necessary and the screen changes “number”, the “number” can be set more quickly. In order to make it possible, the “number” screen is changed more quickly so that the operator can easily operate the screen.

In ST17, it is determined whether or not the changed portion, that is, the number “3” in the above example, has been changed. Specifically, it is determined whether or not the “OK key 12” in FIG. 2 has been pressed.
This determination is performed by the “changeable part determination determination processing unit (program) 38” in FIG.

When it is determined in ST17 that the change of the changeable part has been completed, the process proceeds to ST18. In ST18, the infusion pump 10 determines whether or not the changeable part displayed on the “infusion pump display 20”, that is, all the numbers “300.00” in the above example have been changed.
Specifically, the “all changeable part confirmation determination processing unit (program) 39” of FIG.

If it is determined in ST18 that all the changeable parts have not been changed, the process proceeds to ST19, and the next change part, in the above example, the right-hand side of the number “3” at the 100th place in FIG. The number “0” is underlined and can be changed.
This operation is also performed by the “changeable part confirmation determination processing unit (program) 38” in FIG.

  Next, in ST20, the same process as in ST18 described above is performed. As described above, in the present embodiment, when all the changeable parts, for example, the numbers “300.00” are changed (“OK key 12” is pressed) or when a predetermined time has elapsed. Then, it is determined that all the changeable parts have been changed, and the “changeable screen” is ended.

As described above, in the present embodiment, the background color of the display screen of each normal setting information is set to “light blue”, and after that, when the screen is selected and becomes the selected screen, the background color is changed from “light blue” to “ It is changed to “light blue” (ST8). Further, when the screen is changed to the changeable screen, “light blue” becomes “dark light blue” (ST10).
Therefore, in this embodiment, the more specific the editing of the setting screen is, the darker the background color becomes. Therefore, an operator such as a medical worker can concentrate by the operation, and an operation error is caused in advance. Can be prevented.

When it is determined in ST18 that all the changeable parts have been changed and the “changeable screen” is completed, the process proceeds to ST21.
In ST21, the background color of “infusion pump display 20” returns from “dark light blue” to “light light blue” which is the background color in the normal state.
Therefore, the operator can clearly grasp that the setting change of the infusion pump 10 has been completed.
Specifically, the “infusion pump display thin light blue display processing unit (program) 40” of FIG. 3 operates.

Thus, in the present embodiment, the screen transitions (changes) at the most appropriate speed based on the operation speed of the display change dial 11 of the operator and the screen information displayed on the “infusion pump display 20”. Therefore, the infusion pump 10 that is most easily operated by the operator and has a screen transition is obtained.
As the background color of the infusion pump display 20, the background color in the non-selected state is “light blue”, the background color in the selected state is “light blue”, and the background color in the changed state is “dark blue”. Although the example to make was demonstrated, you may make it change the display of the background color of the infusion pump display 20 by three different colors.
In addition, the background color of the infusion pump display 20 may be set to two colors by using the same color as the “dark light blue” that is the background color in the selected and changed state and “light blue” that is the background color in the non-selected state. However, two colors of different colors may be used.

That is, when the type of information displayed on the infusion pump display 20 is, for example, a numerical value change screen with many digits, it is necessary to operate the display change dial 11 for a long time for the change. In the case of an item selection screen for 10 setting information (flow rate setting, etc.), it is not necessary to operate the display change dial 11 for a long time to switch the item.
Therefore, in such a case, in the numerical value change screen, the display information change speed by the display change dial 11 is set faster than in the item selection screen, and the numerical value change or the like can be executed quickly.
On the other hand, in the item selection screen, the change speed of the display information by the display change dial 11 is set as usual, and the change speed is not too fast for the operator and is easy to operate.
Therefore, in the present invention, the operator can easily set the infusion pump 10.

  In this embodiment, settings such as “liquid level display”, “scheduled volume / scheduled time display”, “cumulative volume display”, etc. are very important. In the case of a change, due to the difference in the editing process of the setting change, in other words, the normal setting information display screen, selected screen, changeable screen gradually darkens the background color and draws its attention. It has become. For this reason, it is the infusion pump 10 in which operators, such as a medical worker, do not carry out an erroneous operation easily.

  By the way, the present invention is not limited to the above-described embodiment. In the present embodiment, the infusion pump 10 has been described as an example of a medical device. However, the present invention is not limited to this, and other liquid feeding devices such as a syringe pump, an artificial heart lung device, an intravascular ultrasound diagnostic device, and the like. It can be suitably applied to medical devices.
