DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed form medium such as a medical chart and an information management apparatus suitable for managing and operating information written on the fixed form medium.

[0002]

2. Description of the Related Art A traditional method for managing and operating a plurality of pieces of document information having a specific meaning, for example, document information sequentially added at different dates and times and having a meaning as a whole, is predetermined. A method has been adopted in which document information is additionally and additionally written on a fixed form medium, and the fixed form medium is always stored on a predetermined management shelf or the like.

[0003] On the other hand, with the spread of computer systems in recent years, there is an increasing trend to efficiently manage and operate by converting document information into electronic data and storing it in a mass storage device.

[0004]

However, the former traditional method and the latter method of converting to electronic data each have their advantages and disadvantages. The paper medium used in the traditional method is excluded, and the conversion of electronic data is performed. If the method is specialized, there is a problem that the document information cannot be properly managed and operated.

[0005] For example, in the medical field, a doctor is obliged to always fill in a medical chart, which is a standard paper medium, with diagnostic results and prescription information. By additionally filling in the same medical chart, the patient's history information is collectively managed by the medical chart. In other words, the diagnosis results and the history of the prescription are entered in the medical chart correlated with the patient on a one-to-one basis, thereby ensuring that medical errors are prevented from occurring and appropriate medical practices are performed.

[0006] Medical charts are paper media that are suitable for doctors and nurses to handle because of their excellent portability and visibility, and if all of them are replaced with electronic data, medical doctors and nurses will not be able to use them. There was a problem that it would hinder quick and appropriate medical treatment for women and the like.

[0007] However, it is sometimes burdensome for doctors and nurses to properly store and operate an enormous amount of medical charts. Building is also necessary. In particular, in order to cope with a large number of patients with different types of illness and injuries, it is sometimes burdensome to properly store and operate medical charts. The place that should be stored and operated in association with
The necessity of preventing the occurrence of accidents such as accidental operation has led to the discussion of the effectiveness of introducing a method of digitizing data.

[0008] For this reason, there is a demand for the development of an information management device for converting into electronic data that can be constructed so as to be easy for doctors and nurses to handle and to concentrate on medical care.

As one conventional example, the advantages and disadvantages of medical charts and electronic data in the medical field have been described in comparison, but document information is managed in other fields, that is, using a standard paper medium.・ Similar issues exist in other fields in which we operate.

The present invention has been made in view of the above problems, and provides an information management apparatus suitable for appropriately managing and operating a fixed form medium and information written on the fixed form medium. With the goal.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a fixed form medium and an information management apparatus for managing and operating information described on the fixed form medium.

The configuration includes a management data generation unit that generates data, and a control unit that stores the management data in a built-in storage unit or an external storage unit.

According to this configuration, the new identification information is automatically printed on the new fixed-size paper medium, and the built-in storage means or the external storage means stores the new electronic information of the information described on the fixed-size paper medium. Management data to which the identification information is added. For this reason, the management data stored in the standard paper medium and the built-in storage means or the external storage means can be managed and operated on a one-to-one basis based on the identification information, and appropriate management and operation can be achieved. Can be.

When the determining means determines that the electronic data contains predetermined identification information, the printing means does not print the new identification information on the standard paper medium.

According to this configuration, when the determination means determines that the predetermined identification information is included in the electronic data, the identification information is already attached to the fixed form paper medium. . Therefore, in this case, without printing new identification information, based on the identification information already attached,
The standard paper medium and management data stored in a built-in storage unit or an external storage unit are managed and operated.

The management data generating means, when the determining means determines that the predetermined identification information is not included in the electronic data, the management data stored in the internal storage means or the external storage means. Calculating a difference between the electronic data included in the electronic data and the electronic data output from the reading unit, and using the difference data as the electronic data for generating the management data with the identification information. And

According to this configuration, the difference between all the information of the fixed form medium to which the new information is added and the electronic data included in the old management data stored in the built-in storage means or the external storage means. , Only the newly added information is extracted. The data of the extracted difference is included in the management data and sequentially stored in the built-in storage unit or the external storage unit. As a result, the management data can be stored, managed, and operated without consuming a large storage area of the internal storage means or the external storage means.

For example, as shown in FIG. 4, a plurality of n (n is an arbitrary natural number) information management apparatuses 1 are connected via a communication port 31 to a ring LAN transmission line laid in a large hospital. By connecting the nodes, the terminal can be used as a terminal device for a host computer having a large-scale database system.

Next, the operation of the information management apparatus 1 having such a configuration will be described with reference to FIGS. FIGS. 5A to 5C and FIGS. 6A to 6C show the case 5
FIG. 4 is an explanatory diagram schematically showing the operation of a reading and printing mechanism provided inside the printer.

In FIG. 5 (a), when a user such as a doctor or a nurse inserts the medical chart P through the insertion slot 4, the medical chart P is moved toward the transport rollers 9a and 9b along the guide member 7 by its own weight. Moving. During this movement, the light receiving sensor 13 optically detects the passage of the distal end of the medical chart P, and supplies a detection signal to the system controller 21.

When the system controller 21 receives the detection signal from the light receiving sensor 13, the system controller 21 controls the actuator driving section 27 and controls the transport rollers 9b, 10b, 11b,
12b is urged toward the conveying rollers 9a, 10a, 11a, and 12a, and the drive motor 19 is driven in a predetermined direction (hereinafter, referred to as
(Referred to as forward rotation direction). Thereby, the medical chart P is transported by the transport rollers 9a, 9b, 10a, 10
b, 11a, 11b, 12a, and 12b, and is carried into the housing part 5 at a constant speed.

Next, as shown in FIG. 5B, when the medical chart P passes through the light receiving sensor 14, the light receiving sensor 14
, A detection signal indicating that the medical chart P has passed is output, and the system controller 21 receives the detection signal and causes the image sensor 16 to start a reading operation. Then, the image sensor 16 reads the information on the paper surface of the medical chart P carried in at a constant speed in synchronization with the reading scanning timing of a predetermined period, and stores the read image data DG in the video memory 24.

That is, the image sensor 16 reads the information in the width direction (sub-scanning direction) of the medical chart P line-sequentially by a large number of fine photodiodes arranged in the longitudinal direction, and reads the information at the predetermined period. The main scanning is performed by repeating this line-sequential reading in synchronization with the scanning timing, and information on the entire surface of the medical chart P is converted into one-frame two-dimensional image data DG in the video memory 2.
4 is stored.

Next, as shown in FIG. 5C, when the end portion of the medical chart P passes through the light receiving sensor 15, the light receiving sensor 15 optically detects the passage and outputs a detection signal. Then, the system controller 21 terminates the reading operation of the image sensor 16 based on the detection signal and stops the driving motor 19. Thereby, the medical chart P is held by the guide member 8,
At the same time, it stops while being nipped by the transport rollers 11a, 11b, 12a, 12b.

Next, the system controller 21 analyzes the image data DG stored in the video memory 24, and performs processing for managing and operating information and the like entered in the medical chart P. The processing for management and operation will be described later with reference to FIGS.

FIGS. 6A to 6C show the operation when the reading / printing mechanism 6 carries out the medical chart P again from the insertion port 4 after the processing for the management and operation has been performed. ing.

In FIG. 6A, after the system controller 21 completes the management and operation processes,
The medical chart P is carried out in the direction of the insertion slot 4 by rotating the drive motor 19 in the reverse direction (rotation direction opposite to the normal rotation direction). And medical chart P
When the front end portion (the end on the side of the insertion port 4) passes through the light receiving sensor 15, a detection signal is output from the light receiving sensor 15, and the system controller 21 receives the detection signal and the actuator 27 and the print driving unit 28 And printing by the print head 17 is started.

Next, as shown in FIG. 6B, when the system controller 21 receives the detection signal from the light receiving sensor 15, the system controller 21 starts the above-described printing operation in synchronization with the detection signal. The print head 17 is moved forward and backward with respect to the medical chart P while specifying the position on the medical chart P where the medical chart P is to be printed based on the rotation speed information, and further, the heating element of the print head 17 is heated based on the print data. As a result, the medical chart P is transferred by the thermal transfer ink ribbon fed from the print cartridge 18.
To print.

Although the details will be described later, when a new medical chart P is inserted, an identification marker for identifying the new medical chart P when the new medical chart P is carried out. (Identification code: ID) is printed as a barcode.

Next, as shown in FIG. 6C, when the terminal portion of the medical chart P passes through the light receiving sensor 15, a detection signal is output from the light receiving sensor 15, and the system controller 21 outputs the detection signal to the detection signal. By retreating the print head 17 when a predetermined period has elapsed in synchronization,
The printing operation ends.

When the end portion of the medical chart P passes through the light receiving sensor 14, a detection signal is output from the light receiving sensor 14, and the system controller 21 synchronizes with the detection signal at a point in time when a predetermined period has elapsed. By stopping the rotation of the drive motor 19, the medical chart P
To the insertion slot 4.

That is, by rotating the transport rollers 9a and 9b in reverse until a predetermined time has elapsed since the light receiving sensor 14 outputs the detection signal, the medical chart P
Is completely moved to the insertion port 4 side of the transport rollers 9a and 9b, and the medical chart P is completely released from the state of being pinched by the transport rollers 9a and 9b, and then the rotation of the drive motor 19 is stopped. Thereby, a user such as a doctor or a nurse can easily take out the medical chart P from the insertion slot 4.

When a user such as a doctor or a nurse takes out the medical chart P from the insertion slot 4, the light receiving sensor 13
Detects the passage of the terminal part of the medical chart P, and the system controller 21 receives the detection signal generated thereby to confirm the completion of the unloading process.

As described above, when the medical chart P is inserted from the insertion slot 4, the reading and printing mechanism 6 reads information and the like described in the medical chart P, and stores the read image data DG in the video memory. 24, and has a function of performing predetermined printing on the medical chart P based on the analysis result of the image data DG and returning it again through the insertion slot 4.

Next, with reference to FIG. 7 and FIG. 8, an operation when the electric circuit 20 analyzes, manages, and operates the image data DG stored in the video memory 24 will be described. FIG. 7 is a flowchart showing the operation of the electric circuit 20, and FIG.
FIG. 4 is an explanatory diagram showing a logical data structure of management data generated for management and operation.

A LAN is constructed as shown in FIG.
A case where the information management device 1 is used as a terminal device for a host computer will be described. In this case,
It goes without saying that the host computer and the information management device 1 are set in a state where bidirectional communication based on a predetermined protocol is possible. It is assumed that a large-scale storage device is installed on the host computer side, and data transmitted from the information management device 1 is file-managed according to a predetermined algorithm.

In FIG. 7, when a user such as a doctor or a nurse operates the operation unit 3 to start a management / operation program, a process for management / operation in the information management apparatus 1 is started.

In step 100, the process waits until a medical chart P is inserted. When the medical chart P is inserted, the process proceeds to step 102, where the reading and printing mechanism 6 is operated to read the medical chart P, and the image data DG is stored in the video memory 24.

Next, after the operation of the reading and printing mechanism 6 is stopped in step 104, in step 106,
The system controller 21 starts analyzing the image data DG.

First, the fixed format data of the medical chart stored in the ROM 22 and the image data DG in the video memory 24 are compared by a pattern patching method or the like. Fixed format data consisting only of ruled lines, printed characters, and the like, which are printed in advance on an unused (unfilled) medical chart, is stored in the ROM 22 in advance, and the fixed format data and the image data DG are stored in the ROM 22 in advance. By contrast,
It is determined whether a regular medical chart has been inserted.
That is, it is analyzed whether or not at least the fixed format data is included in the image data DG. If the fixed format data is not included, it is determined that the regular medical chart has not been inserted, and the image data DG is forcibly determined. The reading and printing mechanism 6 is caused to perform a carry-out operation, is ejected from the insertion slot 4, and is warned by displaying the fact on the display unit 2.

On the other hand, when at least the fixed format data is included in the image data DG, it is determined that a regular medical chart has been inserted, and the process proceeds to step 108.

In step 108, it is analyzed whether or not the image data DG contains barcode data for an identification mark (ID).
It is determined that the medical chart already printed with the ID bar code, that is, the medical chart for the revisited patient is inserted.

Then, steps 104 and 108
Finally, it is determined that the medical chart for the re-examined patient has been inserted based on both analysis results, and the process proceeds to steps 200 to 216.

On the other hand, if it is finally determined that a new medical chart has been inserted based on the analysis results of both step 104 and step 108, the process proceeds to steps 300 to 314.

As described above, in the present embodiment, step 1
Based on the analysis results of both Step 04 and Step 108,
By judging whether the medical chart is a regular medical chart and is the first medical examination or the re-examination, an unexpected accident such as a case where a document out of the target is inserted is prevented beforehand.

However, the analysis result of whether or not bar code data for ID is present in the image data DG may be the highest priority criterion, and the analysis result of step 104 may be a subordinate criterion. The determination may be made only based on the analysis result of whether or not the barcode data for ID exists in the image data DG.

When the processing shifts from step 108 to step 300, processing for managing the inserted new medical chart P is started. First, in step 300, the host computer is called, and a request is made to transfer new ID data. Then, when new ID data is transferred, it is received and acquired.

In step 302, the image data DG stored in the video memory 24 is converted to a JPEG (Joint Photo
The management data KD (ID) is generated by compressing the data by an ographic expert group or the like, adding the acquired ID data and data of a predetermined bibliographic item, and further encrypting the data. That is, as shown in FIG. 8A, the management data KD (ID) before encryption includes ID table data (IDT),
Patient identification data (KAT), doctor's data (DRT),
It is configured as unit frame data including user data (KKT), auxiliary data (PD), etc., and by encrypting this frame data, encrypted management data KD
Generate (ID).

Here, ID table data (IDT)
Is composed of a visit history table for storing, in addition to the acquired ID data, data on the date and time when the patient visited the hospital, predetermined identifier data corresponding to the data on the date and time, and the like.

The patient identification data (KAT) is composed of personal information data such as the patient's name, date of birth, and gender.
It should be noted that data input by a doctor or a nurse operating the operation unit 3 with a keyboard is assigned to the personal information.

The in-charge doctor data (DRT) is composed of data of personal information such as the name and the affiliation of the in-charge doctor who attended the consultation, and is based on the personal information of the in-charge doctor set in the information management apparatus 1 in advance. Automatically generated. When the doctor in charge operates the operation unit 3 to enter the personal information by keyboard at the time of generation of the management data KD (ID), the personal information of the doctor in charge, which is input by the keyboard, is converted to the doctor data (DRT) only in that case. ).

The user data (KKT) is data obtained by using the compressed image data DR as diagnostic data and associating the diagnostic data with the identifier data. It should be noted that this diagnostic data is sequentially added every time a patient comes to the hospital. As a result, even if two or more visits are made, all diagnosis results and prescription history information can be managed without omission.

The auxiliary data (PD) is composed of a so-called error detection code and parity data.

Next, in step 304, a request for permission of data transmission is made to the host computer, and if the request is accepted, the encrypted management data KD is transmitted.
(ID) is transmitted to the host computer, and in step 306, when receiving confirmation information of the reception completion is received from the host computer, it is determined that communication has been normally performed, and the process proceeds to step 308. By receiving this confirmation information, it is determined that the management data KD (ID) has been securely stored in the large-scale storage device provided in the host computer and that the file has been managed.

On the other hand, when the information of the occurrence of the abnormality is received from the host computer, the flow shifts to step 316 to display a warning to that effect and display a countermeasure on the display unit 2, and after the recovery, the processing from step 100 is started again. I do.

The above steps 306 to 308
In step 310, the stopped reading and printing mechanism 6 is activated, and in step 310, the medical chart P is unloaded. Here, the newly acquired ID data is converted (encoded) into the corresponding bar code data and supplied to the print head 17, and the bar code corresponding to the ID data is printed at a predetermined position on the new medical chart P. Let it.

Next, in step 312, it is determined based on the detection output of the light receiving sensor 13 that the medical chart P carried out has been taken out by a doctor or the like, and the operation of the reading / printing mechanism 6 is stopped. The detection signals of all the light receiving sensors 13, 14, 15 in the printing mechanism 6 are checked again,
A final confirmation is made as to whether the unloading operation has been completed normally.

If a signal indicating the presence of a foreign substance is detected among the above detection signals, it is determined in step 314 that normal unloading processing has not been performed, and the flow shifts to step 316 to display the display unit. In step 2, a warning is displayed and a countermeasure is displayed, and after the recovery, the processing from step 100 is started again.

On the other hand, when the final confirmation that the unloading operation has been completed normally is performed, the process returns to step 100 and waits until the next medical chart is inserted.

As described above, in steps 300 to 314, when the doctor in charge describes the diagnosis result and prescription in the new medical chart and inserts it into the information management apparatus 1, the new medical chart corresponds to the first-time patient. Automatically print barcodes. Further, since the ID data corresponding to the barcode and the information of the diagnosis result and the prescription are managed as files in the host computer as management data KD (ID), the medical chart and the management data KD (ID) are stored in the host computer. The management can be reliably performed between the computer and the computer.
In addition, the barcode is automatically printed,
The medical chart and the management data KD (ID) can be managed in association with each other without cumbersome work for doctors and nurses.

In step 108, it is determined that the barcode data as the identification mark (ID) is included in the image data DG, and the process proceeds to step 200. It is determined that the medical chart P has been inserted, and the following processing is performed.

First, in step 200, the image data D
The barcode data contained in G is transmitted to the host computer, and a request is made to return the management data KD (ID) file-managed with the ID corresponding to the barcode data. Then, when the management data KD (ID) is transferred in response to the request, it is received and acquired.

Next, in step 202, the encrypted management data KD (ID) is decrypted, and all the diagnostic data included in the management data KD (ID) are decompressed. Then, each diagnostic data is restored to the form of two-dimensional image data. Furthermore, by adding each image data for each pixel data of the same arrangement,
The medical chart data KK (ID) is restored to the same format as the information described in the medical chart P (the same format as the image data).

Next, in step 204, the difference between the image data DG obtained in step 102 and the chart data KK (ID) is calculated for each pixel. Then, the image data DG and the chart data KK (I
The difference data δ [DG-KK (ID)] representing only the difference from D) is generated.

That is, the restored chart data KK (ID) is the same as the information described in the medical chart up to the previous examination, and the image data DG is the same as the information of the chart data KK (ID). In addition, it includes new information added to the medical chart in this diagnosis. Therefore, the difference δ [DG-KK (I) between the image data DG and the chart data KK (ID)
D)], only new information added to the medical chart in this diagnosis is extracted.

Next, in step 205, the differential data δ [DG-KK (ID)], which is new information added to the medical chart in the current diagnosis, is compressed, and the compressed differential data δ [DG −KK (ID)] as the latest diagnostic data. Further, bibliographic data is added to the visit history table of the ID table data (IDT) shown in FIG. 8, and an identifier is added to the compressed difference data δ [DG-KK (ID)] to add user data (KKT). Figure 8
The latest management data KD (ID) including the predetermined frame data shown in (a) is generated.

Then, by encrypting the management data KD (ID), the encrypted management data KD (ID) is generated.

Here, the reason for obtaining the difference data δ [DG-KK (ID)] will be described. A medical chart, which is a paper medium, is a record to which information such as a diagnosis result and a prescription is sequentially added every time a medical examination is performed. That is,
Information such as the latest diagnosis result is added to the past history information.

Therefore, the information described in the medical chart is read by the reading / printing mechanism 6 and the image data D is read.
When converted to G, this image data DG includes past history information as well as the latest diagnosis result information. Since such past history information is inserted and read into the information management device 1 at each examination, if the image data DG is simply stored and managed,
The past history information is redundantly stored in the storage device of the host computer, and the storage area of the storage device cannot be used effectively.

Therefore, the difference δ [DG−DG) between the image data of the previous medical chart and the image data of the current medical chart is obtained.
KK (ID)] to extract the image data of the information newly added to this medical chart, and compress this difference image data to reduce the amount of information without compromising the amount of information. Data is generated, and the compact data is used as diagnostic data.

Further, the above-mentioned identifiers are assigned to the respective diagnostic data generated at each consultation, and all of them are assigned to user data (KKT) and stored and managed. Therefore, as described above, by adding all these diagnostic data, the medical record data KK (ID) equivalent to the history information actually described in the medical chart is restored. Then, by calculating the difference between the chart data KK (ID) and the image data DG read by the reading and printing mechanism 6, the difference δ [DG-KK (I
D)]. This makes it possible to effectively use the storage area of the storage device.

Next, in step 208, a request for permission of data transmission is made to the host computer, and if the request is accepted, the encrypted management data KD (ID)
Is transmitted to the host computer, and in step 210, when the confirmation information of the reception completion is received from the host computer, it is determined that the communication has been normally performed, and
It moves to 12. By receiving this confirmation information, it is determined that the encrypted management data KD (ID) is securely stored in the large-scale storage device provided in the host computer, and that the file has been managed.

On the other hand, when the information of the occurrence of the abnormality is received from the host computer, the process proceeds to step 218, where a warning display and a countermeasure are displayed on the display unit 2, and after the recovery, the process from step 100 is started again. I do.

The above steps 210 to 212
Then, the stopped reading and printing mechanism 6 is activated, and the medical chart P is carried out. Here, step 2
The medical chart P processed after 00 is related to the second and subsequent medical examinations. Since the ID barcode has already been printed, the printhead 17 does not need to print the barcode. Only carry out.

Next, in step 214, it is determined based on the detection output of the light receiving sensor 13 that the medical chart P that has been taken out has been taken out by a doctor or the like, and the operation of the reading and printing mechanism 6 is stopped. At 216,
All the light receiving sensors 13, 14, 15 in the reading and printing mechanism 6
Is checked again to make a final confirmation as to whether or not the unloading operation has been completed normally.

If a signal indicating the presence of a foreign substance is detected among the above detection signals, it is determined that normal carry-out processing has not been performed, and the process proceeds to step 218, and the display unit 2 indicates that. Is displayed and a countermeasure is displayed, and after the recovery, the processing from step 100 is started again.

On the other hand, when the final confirmation that the unloading operation has been completed normally is performed, the process returns to step 100 to be in a standby state until the next medical chart is inserted.

As described above, in steps 200 to 218, when the doctor in charge describes the diagnosis result and the prescription in the medical chart relating to the second and subsequent examinations and inserts the result into the information management apparatus 1, the doctor additionally writes the information. Information (diagnosis data) is managed and operated by including it in the management data KD (ID).

As a result, the storage area of the storage device can be used effectively. Although not shown in the flowchart of FIG. 7, the doctor or the like operates the operation unit 3 to appropriately convert the individual examination data assigned to the user data (KKT) in the management data KD (ID). By synthesizing, it is possible to obtain history information for each medical examination progress, and to provide an effective means for medical work.

Further, since a bar code for ID is printed on the medical chart and the management data KD (ID) relating to the patient is managed and operated on the storage device based on the information of the bar code, reliable and proper management and management can be achieved. Operation becomes possible.

Further, since the management data KD (ID) is encrypted and managed, it is possible to prevent secret leakage to outsiders.

In this embodiment, the case where the encrypted management data KD (ID) is stored and managed in the storage device provided on the external host computer side has been described. It is not limited to the mode of use.
For example, the information management apparatus 1 incorporates a large-capacity storage device such as a hard disk, and executes a predetermined program under a so-called disc operating system (OS) to encrypt the management data KD. (ID) may be stored, and management and operation similar to the above may be performed. According to such a configuration, even in a relatively small hospital such as a private hospital, the information management apparatus can efficiently and appropriately manage and operate patient diagnostic information and the like.

As the identification information, in addition to a one-dimensional barcode or a two-dimensional barcode, other forms of identification information may be printed.

In the present embodiment, the information management apparatus used in the medical institution has been described, but the present invention is not limited to this. In other words, the present invention can be applied to other fields in which document information is managed and operated using a standard paper medium.

[0107]

As described above, according to the present invention, a new fixed form medium is automatically printed and managed with new identification information, and a fixed form medium to which identification information is already attached is newly identified. The information is managed based on the existing identification information without printing, and the information on the fixed form paper medium is converted into electronic data, and the management data obtained by adding the identification information to the electronic data is stored in the storage means. Therefore, the management data stored in the fixed form medium and the internal storage means or the external storage means can be managed and operated in one-to-one correspondence based on the identification information.

Further, new identification information is printed on the standard paper medium, and after the printing, the standard paper medium itself corresponds to the management data stored in the built-in storage means or the external storage means based on the identification information. In addition, it can be managed and operated. As a result, the management data stored in the built-in storage unit or the external storage unit can be managed and operated in the same sense as handling a standard paper medium.
It is possible to provide a user-friendly information management device.
