FIG. 4 is a schematic diagram showing the main internal configuration and the like of the medical pump 2, and FIG. 5 is a schematic diagram showing the main internal configuration and the like of the internal information reader 4.
6 and 7 are schematic flowcharts showing main operations and the like of the internal information reading system 1 of the present embodiment.
Hereinafter, the internal information reader 4 and the internal configuration of the medical pump 2 and the like will be described together with explaining the process of acquiring the history data in the medical pump 2.
FIG. 4 is a schematic diagram showing the main internal configuration and the like of the medical pump 2, and FIG. 5 is a schematic diagram showing the main internal configuration and the like of the internal information reader 4.
6 and 7 are schematic flowcharts showing main operations and the like of the internal information reading system 1 of the present embodiment.

First, as shown in FIG. 1, a user who uses the internal information reading system 1 arranges a camera 3 in front of the pump-side display 21 of the medical pump 2 in which history data is stored. The internal information reading device 4 is connected to 3.
In this state, as shown in ST1 of FIG. 6, the user activates the internal information reading device 4. Specifically, the information reading device control unit 42 in FIG. 5 executes by referring to the reading software data in the reading software data storage unit 50, and first activates the camera 3 as shown in ST2.
The camera 3 is activated via the camera control unit 31, and the captured image of the camera 3 is displayed on the reading side display 41 (see FIGS. 1 and 5) via the display control unit 41a.

On the other hand, the medical pump 2 is switched to the internal data continuous display mode by the user in ST101 of FIG. Specifically, it is executed when the internal user switches the mode changeover switch 23 provided in the medical pump 2 of FIG.
By switching to the internal data switching display mode, the pump-side display 21 of the medical pump 2 is changed to a mode in which the history data of FIG. 3 is continuously displayed.
Specifically, when the mode switch 23 in FIG. 4 is operated by the user, the process proceeds to ST102 in FIG. In ST102, the medical pump control unit 80 in FIG. 4 executes with reference to the pump side segment recognition data in the pump side segment recognition data storage unit 81.
This pump-side segment recognition data is, for example, repeated data of all the lights on and off of the pump-side display 21 in FIG. 2, and this is an example of a spare signal.
Therefore, in ST102, according to the instruction from the medical pump control unit 80, the upper display unit 211, the middle display unit 212, and the lower display unit 213 of the pump side display 21 are all turned off and turned off via the pump side display control unit 22. Will repeat.

Next, in ST3 of FIG. 6, the internal information reader 1 determines whether or not it has received a pump-side segment recognition signal. Specifically, in ST102, the camera 3 captures a repetitive signal of all lamps displayed on the pump side display 21 and turning off. The image of the repetitive signal of all the lights and extinguishing of the pump-side display 21 taken as an example is an example of the preliminary signal image information.
Then, the internal information reading device 1 transmits an image of the repetition signal of all the lights on and off of the pump side display 21 via the information reading device control unit 42 and the like in the reading side segment recognition signal data storage unit 51 of FIG. Compare with the segment recognition signal data on the reading side.
This reading-side segment recognition signal data is, for example, repeated data for turning on and off the pump-side display 21 and is an example of preliminary signal image comparison information. Therefore, by this comparison, the internal information reader 1 determines whether or not the medical pump 2 has displayed a repetition signal for turning on and off all lights on the pump-side display 21 or whether or not the repetition signal for turning off all lights and turning off. It is possible to determine whether or not it has been received.

In ST3, if the internal information reading device 1 cannot receive all the lights on and off the pump-side display 21 of the medical pump 2 repeatedly, the position of the camera 3 relative to the medical pump 2 may be inappropriate. Then, for example, a message indicating that “the repetition signal for turning off all the lights on the pump side display 21 and turning it off cannot be received” is displayed on the reading side display 41 of the internal information reader 1.
The user who sees this display can know that the position of the camera 3 is not appropriate, and can correct the position of the camera 3 to an appropriate position.

On the other hand, if the internal information reading device 1 has received a repetition signal for turning on and off the pump-side display 21 of the medical pump 2 via the camera 3 in ST3, ST4, ST5 and ST6 in FIG. Proceed to ST7.
In ST4, the brightness data of the captured image is compared with the brightness basic data. That is, the internal information reading apparatus 1 has a brightness measuring device (not shown), and using this brightness measuring device, the brightness of the image of the repetitive turn-off signal and all the lights of the pump-side display 21 captured by the camera 3 is obtained. measure.
In ST5, the measured luminance data is compared with the basic luminance data (an example of preliminary signal image comparison information) in the basic luminance data storage unit 52 in FIG. It is determined whether or not the luminance of the image of the repetitive signal of all 21 lights and turn-off is within an appropriate range.
Specifically, the luminance basic data is, for example, 250 to 300 sd / m ² (candela / square meter), and the luminance of the image of the repetition signal indicating that all the lights of the pump-side display 21 and the extinguished light captured by the camera 3 are within this range. If it is within, it is judged that the luminance is appropriate.

If it is determined in ST5 that the luminance is not within the proper range, for example, “the luminance of the repetitive signal indicating that all the lamps on the pump side display 21 are turned off and off is not within the proper range. Is displayed.
The user who sees this display can know that the position of the camera 3 is not appropriate, and can correct the position of the camera 3 to an appropriate position.

In ST6, the light emitting segment data is acquired from the captured image, the coordinate data is grasped, and the grasped coordinate data is compared with the coordinate basic data. That is, the internal information reader 1 grasps positions corresponding to the upper display unit 211, the middle display unit 212, and the lower display unit 213 of the pump-side display 21 from the light emitting part.
This is determined by, for example, coordinate data based on a reference point (for example, the center of the upper end) of the pump-side display 21 in the captured image.
Next, in ST7, the coordinate data is obtained, the light emitting portions corresponding to the upper display unit 211, the middle display unit 212, and the lower display unit 213, and the coordinate basic data (in the coordinate basic data storage unit 53 in FIG. 5) ( Compared with an example of preliminary signal image comparison information), the light emitting portions corresponding to the upper display unit 211, the middle display unit 212, and the lower display unit 213 of the pump-side display 21 captured by the camera 3 are in appropriate positions. Determine whether or not.
Specifically, the coordinate basic data includes coordinate (X, Y) data in which the positions of the upper display unit 211, the middle display unit 212, and the lower display unit 213 are from the reference point (the upper center portion of the pump-side display 21, etc.). If the light emitting portions corresponding to the upper display unit 211, the middle display unit 212, and the lower display unit 213 of the pump-side display 21 captured by the camera 3 are within the range of this coordinate data, the position is appropriate. It is judged.

When it is determined in ST7 that the coordinate position is not within the proper range, for example, “the position of the pump side display 21 is not within the proper range” is displayed on the reading side display 41 of the internal information reading apparatus 1.
The user who sees this display can know that the position of the camera 3 is not appropriate, and can correct the position of the camera 3 to an appropriate position.

As described above, in the present embodiment, the internal information reading device 4 captures the display of the pump-side display 21 of the medical pump 2 via the camera 3 and acquires history information such as history data therein. Previously, a plurality of steps for adjusting the relative position of the camera 3 and the medical pump 2 are performed in order to prevent erroneous reading of the display. For this reason, the history information such as internal history data, which is performed thereafter, can be acquired without fail in an appropriate and reliable manner.
Specifically, this adjustment process is not limited to whether or not “the segment recognition signal has been received”, but also whether the “brightness data of the captured image” is within a predetermined range, It is also determined whether it is within a predetermined range of the “coordinate basic data” and proceeds to the next step only when these are all within an appropriate range.
Therefore, it is ensured that the acquisition of the data is surely executed in the subsequent acquisition process of the history information such as the internal history data.

If it is determined in ST5 and ST7 in FIG. 6 that the values are within appropriate ranges, the process proceeds to ST8. In ST8, “ready for continuous imaging of internal data” is displayed on the reading-side display 41 of the internal information reader 4.
That is, such a display is displayed on the reading-side display 41, and the camera 3 is ready to be imaged by the camera control unit 31.

The user who sees the display of ST8 on the reading-side display 41 of the internal information reader 4 presses the internal data continuous display start key switch 24 of the medical pump 2.
If the medical pump 2 determines that the internal data continuous display start key switch 24 has been pressed in ST103 of FIG. 6, continuous display of internal data is started in ST104.
Specifically, when the medical pump control unit 80 in FIG. 4 detects pressing of the internal data continuous display start key switch 24, the history data shown in FIG. 3 stored in the internal data storage unit 82 is pumped in order of history numbers. It is displayed on the side display 21.
At this time, the medical pump control unit 80 displays the data by referring to the normal display data stored in the normal display data storage unit 83 of FIG.
That is, for example, when numbers are displayed on the upper display unit 211 in FIG. 2, the number portion to be shown is turned on and the other portions are turned off and displayed.
Specifically, as described above, each of the display units 211a to 211g of the upper display unit 211 shown in FIG. 2 includes seven segments (LEDs) for indicating numbers and one segment (LEDs for indicating dots). ), And these are displayed by turning on or off.

By blinking the segments in this way, the numerical data of the history data (an example of the object information and the main body signal information) in FIG. 3 is displayed in order as described above.
In addition, the middle display unit 212 and the lower display unit 213 in FIG. 2 respectively display history data other than numbers, as described above.
The signals displayed on these pump-side displays 21 are an example of main body signals.
As described above, it is not possible to display all the history data of FIG. 3 only by the display units 211 of the pump side display 21 of FIG. 2, but FIG. 2 is a simplified display part, Other display parts are also arranged at predetermined positions.
In addition,

When the display of the history data in FIG. 3 on the pump-side display 21 is started in order of history number, in ST105, all the internal data within the same history number, for example, each data of history number 1 in FIG. It is determined whether it has been displayed.
If it is determined in ST5 that all history data having the same history number has been displayed, the process proceeds to ST106, and this time, the same history data is highlighted.
Specifically, the data is displayed with reference to the reverse display data in the reverse display data storage unit 84 of FIG. That is, contrary to the normal display data displayed in ST104, the numbers and the like to be displayed are turned off and the other portions are turned on to display.
FIG. 9A shows an example of normal display data, and FIG. 9B shows an example of the inverted display data.
As shown in FIG. 9, for example, if the number is “2”, the part indicated by the black letters in (a) is lit in the normal display, and the part indicated by black letters in the (b) is lit in the reverse display.
These normal display data and reverse display data are examples of the different body signals.

Next, the process proceeds to ST107. In ST107, it is determined whether or not all history data having the same history number is highlighted.
If it is determined in ST107 that all history data having the same history number is highlighted, in ST108, the medical pump control unit 80 refers to the history data shown in FIG. 3 in the internal data storage unit 82. Then, it is determined whether or not there is history data having a history number not yet displayed on the pump-side display 21.
If there is history data with a history number not yet displayed on the pump-side display 21, it is displayed as shown in ST109, and the steps ST104 to ST108 are repeated.

  On the other hand, if it is determined in ST108 that there is no undisplayed history data, the continuous display of the internal data ends in ST110.

Next, the operation of the internal information reading apparatus 4 corresponding to the steps from ST103 to ST110 on the medical pump 2 side will be described below.
First, since the internal information reader 4 displays the history data of FIG. 3 on the pump side display 21 in ST104 because the camera 3 is in the imaging state in ST8, the camera 3 displays the signal as it is. An image is captured, and an image is acquired by the image acquisition unit 32 and the like in FIG.

Next, as shown in ST9 of FIG. 6, the internal information reading device 4 cuts out the observation position of the imaged segment. That is, the analysis unit for analyzing the image data stored in the image data storage unit 55 in FIG. 5 is cut out.
As shown in FIG. 5, the cut-out data stored in the cut-out data storage unit 56, for example, the light emitting portion corresponding to the upper display unit 211 includes four display units 211 a in the upper row and three in the lower row. Display unit 211e, etc., the light emission portion corresponding to the middle display portion 212 has one LED, and the light emission portion corresponding to the lower display portion 213 has two LEDs on the left and right. Are stored.
Therefore, the internal information reader 4 cuts out each display unit 211a and the like as shown in FIG.

FIG. 8 is a schematic explanatory diagram showing a state in which the internal information reading device 4 cuts out the observation position of the imaged segment.
As shown in FIG. 8, from the image data stored in the image data storage unit 55 of FIG. 5, the light emitting portion corresponding to the upper display unit 211 of the pump-side display 21 is divided into four upper parts and three lower parts. The display units are 211a to 211g.
In addition, the light emitting portion corresponding to the middle display portion 212 is cut into one middle display portion, and the light emitting portion corresponding to the lower display portion 213 is cut into two pieces on the left and right.
The data of each light-emitting part thus carved is stored in the cut-out data storage unit 57 in FIG.

Further, the inverted display image data displayed on the pump-side display 21 in ST106 of the medical pump 2 is also stored in the image data storage unit 55 of FIG. 5 similarly to the above-described normal display image data, and each upper display unit is displayed. 211, the middle display unit 212, and the lower display unit 213 are cut out and stored in the cut-out data storage unit 57 of FIG. 5 as shown in FIG.
At this time, for example, whether the stored image data is normal display image data or reverse display image data can be identified by a flag displayed by the medical pump 2. For example, when displaying inverted display data on the pump-side display 21, a mark flag may be displayed at the head.

Next, proceeding to ST10, the internal information reading device 4 refers to the data stored in the cut-out data storage unit 57, and determines whether the observation position of the captured segment is the same in the normal display and the reverse display. to decide.
This ST10 may be executed after all the display of history data by the medical pump 2 is completed, or may be executed while imaging and acquiring the history data.
Specifically, the normal display image data and the reverse display image data stored in the cut-out data storage unit 57 in FIG. 5 are compared, for example, by inverting one of the light emission portion and the non-light emission. Determine whether the parts match. In this case, a certain allowable range can be defined as the matching range.

In ST10, when the image data for normal display and the image data for reverse display do not match, as shown in ST12, the acquired image data is determined to be incorrect, and the reading-side display 41 of the internal information reader 4 displays “image acquisition impossible”. Is displayed and the result is notified to the user.
Thus, in the present embodiment, the internal information reader 4 compares normal and inverted image data in order to increase the accuracy of the image data acquired via the camera 3. Therefore, it is possible to acquire image data with extremely high accuracy.

On the other hand, in ST10, when the normal display image data and the reverse display image data match, the process proceeds to ST11 and collates with the display pattern.
That is, the internal information reading device 4 compares the cut-out data in the cut-out data storage unit 57 in FIG. 5 with the display pattern data in the display pattern data storage unit 58 to grasp the meaning of the image data.
The display pattern data includes, for example, numeric data corresponding to the upper display unit 211, ON / OFF data corresponding to the middle display unit 212, air bubbles and / or blockage data corresponding to the lower display unit 213, and the like. This display pattern data is an example of the main body signal comparison information.

Specifically, as shown on the right side of FIG. 8, regarding the upper display section 211, each number is grasped from the shape of the lighting segment (LED) portion such as each display unit 211a.
In addition, regarding the middle display unit 212, it is grasped that the LED is ON when it is emitting light, and is OFF when it is not emitting light.
Further, regarding the lower display unit 213, it is grasped that there is a bubble alarm when the left LED is emitting light, and that there is a blockage alarm when the right LED is emitting light.
In this way, the image data is compared with the display pattern data, and it is determined whether or not the difference is within a certain range, thereby grasping the meaning of the image data (ST13).
Therefore, if the image data is not within a certain range compared to the display pattern data in ST13, the user is informed that “image acquisition is not possible” as in ST12.

On the other hand, when the image data is within a certain range compared to the display pattern data in ST13, the grasped meaning is stored in the display data storage unit 59 of FIG.
At this time, since the item data of the history data in FIG. 3 is registered in the display data storage unit 59 in the order in which the pump-side display 21 displays the data, numerical data whose meaning is grasped in order for each history number, etc. Can be registered in the internal information reader 4 in the display data storage unit 59, similar to the history data in the internal data storage unit 82 in the medical pump 2.

As described above, in the present embodiment, history data registered in the medical pump 2 can be quickly read and registered without installing a special communication device in the medical pump 2.
Further, this reading is performed by taking an image of the display on the pump-side display 21 of the medical pump 2 with the camera 3 and analyzing the image by the computer, so that the reading can be performed at a very high speed.
Therefore, the reading process can be executed at a speed higher than that compared with the case where the user visually reads and reads.

(Second Embodiment)
FIG. 10 is a schematic diagram showing the main internal configuration and the like of the medical pump 200 of the internal information reading system according to the second embodiment of the present invention, and FIG. 11 shows the internal configuration according to the second embodiment. 2 is a schematic diagram illustrating a main internal configuration and the like of the information reading apparatus 300. FIG.
12 and 13 are schematic flowcharts showing main operations and the like of the internal information reading system according to the present embodiment.
Since the internal information reading system according to the present embodiment shares many configurations and the like with the internal information reading system 1 according to the first embodiment described above, the common parts will be described below with the same reference numerals. The description will be omitted below, focusing on the differences.
The main differences between the first embodiment described above and this embodiment are as follows. That is, in the continuous display start process of internal data in ST104 of FIG. 6 of the first embodiment, the pump-side display 21 displays the numbers as they are on the upper display unit 211. However, in the present embodiment, numbers are not displayed as they are, but instead of displaying numbers, a non-character symbol that lights a part of each display unit 211a or the like is used.

Details will be described below. First, after ST103 in FIG. 12, when the internal data continuous display start key is pressed, the process proceeds to ST401. In ST401, the internal data in the internal data storage unit 82 of FIG. 10, for example, the numeric data of the history data of FIG. Convert.
Specifically, the conversion is made with reference to the internal data conversion segment simple display data in the internal data conversion segment simple display data storage unit 201 of FIG. 10, and the conversion will be described with reference to FIG. FIG. 14 is a schematic explanatory diagram of internal data conversion segment simplified display data.
As shown in FIG. 14, for example, the display units 211a to 211g of the upper display unit 211 in FIG. 2 are each composed of eight segments (LEDs) (a) to (h). In the first embodiment described above, seven segments (a) to (g) among these represent numbers, and the segment (h) represents a dot.
However, in this embodiment, among these eight segments, numbers and the like are indicated by combinations of seven segments (a) to (g) excluding the dot portion (segment (h)).

For example, when the date of the history data in FIG. 3 is shown, the total of nine segments of the seven segments of the display unit 211a and the two segments ((a) and (b)) of the adjacent display unit 211b in FIG. Show.
That is, 512 flashing patterns are possible by combining the nine segments to be turned on and off. This combination of blinking patterns of segments is an example of a non-character symbol.
Since there are only 366 days, the month and day can be shown in these nine segments if 512 flashing patterns and a specific month and day corresponding to this are preset. It can be displayed with only nine segments.

Similarly, the time of the history data of FIG. 3 depends on the segments (c) to (g) of the display unit 211b of FIG. 14 and the eleven segments (a) to (f) of the adjacent display unit 211c. It is possible to display with a blinking pattern of 2048.
Similarly, the flow rate of FIG. 3 includes the segment (g) of the display unit 211c of FIG. 14, the segments (a) to (g) of the adjacent display unit 211d, and the segment (a) of the adjacent display unit 211e. ) In a blinking pattern of 512 with a total of nine segments.
Further, the history number in FIG. 3 is also based on a total of 10 segments including the segments (b) to (g) of the display unit 211e in FIG. 14 and the segments (a) to (d) of the adjacent display unit 211f. It can be shown by a flashing pattern of 1024.

In this way, by displaying the history data of FIG. 3 with a combination of blinking patterns of the segments (a) to (g) such as the display unit 211a, the history number, The date, time, flow rate, etc. can be displayed simultaneously.
In this regard, in the display of the first embodiment described above, the history data can be displayed much earlier than when these were displayed in two steps.

The internal data conversion segment simple display data storage unit 201 in FIG. 10 stores correspondence data between the blinking pattern and the history number, date, time, flow rate, and the like.
Therefore, in ST401 in FIG. 12, the medical pump 2 refers to the history data in FIG. 3 stored in the internal data storage unit 82 and the data in the segment simple display data storage unit 201 for internal data conversion, and displays the display unit. The blinking pattern of the segment such as 211a is acquired, and the blinking pattern is displayed on the pump-side display 21 in ST402.

  Next, it is determined whether all the history data within the same history number in FIG. 3 has been converted into segment simple data (segment blink pattern data) and displayed (ST403). When all the display is completed, ST404 is completed. Thus, in the same manner as ST 106 in the first embodiment, reverse display for reversing the blinking of the segment (LED) is executed.

Thereafter, in ST405, it is determined whether or not the reverse display in ST404 has been completed for the history data of all the same history numbers. After that, if there is no history data of other history numbers in ST108, the process ends in ST110.
On the other hand, if there is still undisplayed history data in ST108, the history data is converted into segment simple display data (segment blinking pattern data) in ST406 as in ST401, and the segment simple display data is converted in ST407. Will be displayed.

On the other hand, the internal information reader 4 captures the segment simple display data displayed on the pump-side display 21 of the medical pump 2 with the camera 3 and stores it in the image data storage 55 of FIG. After that, in ST9 of FIG. 12, the segmented observation position of the imaged segment is cut out in the same manner as in the first embodiment, and the observation position of the segment imaged in ST10 is within the same range for normal display and reverse display. If it is determined in ST10 that the segment observation position is within the same range for normal display and reverse display, the process proceeds to ST501 in FIG. Is called.
Specifically, this is a step of referring back to the segment simple data conversion data in the segment simple data conversion data storage unit 301 of FIG. 11 to return the segment simple data to the history data of FIG.
That is, the segment simple data conversion data is reverse to the data in the segment simple display data storage unit 201 for internal data conversion in FIG. 10 described above, and the history number, date, time, Data such as flow rate is stored (an example of non-character / symbol signal comparison information).

  Next, it is determined whether or not the segment simple data captured in ST502 is within the range of the segment simple display data for internal data conversion (ST502). If within the range, the segment simple data is converted into history data in ST503. Then, it is stored in the display data storage unit 59 of FIG.

  As described above, in the present embodiment, since the history data in the medical pump 2 can be quickly and efficiently displayed on the pump-side display 21, the internal information reader 4 is also targeted quickly and efficiently. History data in the medical pump 2 can be acquired.
