Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical information input system and a medical information input method.
The present invention relates to a medical information input system and a medical information input method for inputting medical information such as a prescription.

[0002]

2. Description of the Related Art In hospitals, various records and slips such as medical charts, prescriptions, injection slips, examination slips are used. In recent years, in order to electronically manage charts and the like, a system has been devised for inputting information such as charts and the like to a computer using a keyboard or a mouse. In this system, a doctor inputs medical record information such as a diagnosis result and medications to a computer using a keyboard or a mouse after or during a diagnosis of a patient. The computer display displays graphics that represent the patient's site and the like, and the doctor can interactively perform input work while viewing the graphics. The medical record information input to the computer system can be searched using a key such as a patient name and a patient ID, and as a result, management of the medical record information becomes easy.

Similarly, information such as prescriptions and inspection slips is input to the computer system using a keyboard or a mouse. This computer system includes a plurality of terminals, and prescription information is retrieved from the terminals provided in a pharmacy, for example. Then, the pharmacist can prepare the medicine based on the information obtained from the terminal.

[0004]

However, the conventional medical information input system and medical information input method have various problems as described below.

First, a complicated work is required for data input using a keyboard or a mouse.
In a conventional medical information input system, a doctor or an assistant directly operates a keyboard or the like,
You have to enter medical information. Many doctors who are familiar with conventional handwritten medical records have a strong resistance to inputting medical information using a keyboard or the like, and such an input system is not a substitute for the conventional medical records. In addition, it is legally required to save the medical record in the form of paper, and the medical record information input to the computer system must be saved in the form of paper. For this reason, it is necessary to fill in the medical record as in the past, separately from the data input to the computer system.

Secondly, there is a possibility that incorrect data may be input at the time of key input. Since the key input is performed manually, there is always a possibility that an input error will occur. The above-mentioned erroneous input of medical information causes not only a serious problem on human life but also an economic loss due to an error in medical accounting. Especially, the key input operator
For example, by overlooking a part of the matters described in the medical record, so-called input leakage occurred, resulting in a huge economic loss due to omission of bills.

Thirdly, it has been difficult to provide a smooth medical service. As described above, since it is difficult to input the medical information, there is a delay in medical work such as an increase in patient waiting time.

Fourthly, there has been a problem that the medical record can be easily tampered with. An electronic medical record that does not use any slip has an advantage that data can be easily changed, but this advantage leads to a problem that tampering is easily performed.

The present invention has been made in view of the above-mentioned problems, and a first object of the present invention is to provide a medical information input system and a medical information input method which do not require complicated work for data input. It is in.

A second object of the present invention is to provide a medical information input system and a medical information input method capable of avoiding a data input error.

A third object of the present invention is to provide a medical information input system and a medical information input method capable of improving medical treatment efficiency by providing smooth medical services.

By entering a symbol in the confirmation column of c, the items described in the medical application form are effectively treated as handwriting data. Note that such a cancellation / confirmation column may be provided in the above-mentioned chart.

FIG. 8 is a diagram for explaining a method of correcting an erroneous writing. As shown in the figure, when the patient mistakenly describes only one character of the character string in the medical application form, the line drawing of two lines or the like is overlaid on this character so that the This character can be excluded from the recognition target in the recognition process. For example, if a patient mistakenly wrote "Mu" after "Naka," if the patient accidentally wrote "Maga," then draw "2" over the "Maga" and continue to write "Mura". Can be listed. In such cases,
The character "ga" is excluded from the recognition character string, and "Nakamura" is obtained as the recognition result. If you want to modify the entire character string for one item surrounded by a rectangular frame,
After drawing a double line that spans all of these character strings, write the correct character string outside the frame. At the stage of character recognition, the character string with two lines drawn is excluded from the target of character recognition, and character recognition is performed on the character string outside the frame.

FIG. 9 is a diagram for explaining the correction processing of the coordinate value of the handwriting data. In the medical information input system according to the present embodiment, the medical application form reading device 10
It is possible to correct the inclination of the medical application form even if the medical application form is inclined. That is, the host computer 104a uses the first character 12 of the character string of the medical application form 4.
The respective coordinates of a and the tail character string 12b are obtained, and a straight line passing through both coordinates is calculated. By obtaining the inclination θ between this straight line and the reference line, the inclination of the medical application form 4 with respect to the reading device 10 can be obtained. In addition, medical application 4
The position of can be calculated from the coordinates of the first character 12a and the last character 12b. Therefore, desired data (handwriting data representing an insurance policy number, etc.) can be accurately extracted from the handwriting data, and the clerk does not need to pay attention to the position and angle of the medical application form on the reading device 10. .

FIG. 10 is a diagram for explaining the cancellation processing of the medical application form. As shown in the figure, it is possible to cancel the medical application form by writing a diagonal line on the medical application form 4 with a pen. In this figure, rectangular areas 13a to 13d (not necessarily printed) are provided at four corners of the medical application form 4. The reader 10 includes rectangular areas 13a and 13
When it is detected that the straight line connecting the b and the rectangular regions 13c and 13d is written with a pen, the process of canceling the medical application form is executed. According to the present embodiment, an X mark is described in the medical treatment application form that has undergone the cancellation process, so that the medical treatment application form that has undergone the cancellation process can be easily identified.
Further, there is an advantage that the canceling process can be executed without requiring a complicated switch operation.

Needless to say, the processing shown in FIGS. 8, 9 and 10 is not limited to the medical application form, but can be applied to a chart, an examination slip, and other slips.

II. Action (Action of the entire system) Next, the action of the medical information input system according to the present embodiment will be described. 11 and 12 show
It is a diagram for explaining the flow of medical treatment, which is the first visit, the return visit,
The processing according to the case of reservation is shown. First, when the patient is the first visit, the patient places a medical application form on the terminal 101 for the initial visit, and fills in necessary items on this. The reader 10 detects handwriting data and sends it to the central processing unit 104. After completing the necessary items in the medical care application form, the patient submits the medical care application form and the insurance card to the first consultation reception unit 102. If you have made an appointment for the first visit, you will also be asked to submit the appointment slip to the counter.

In the initial examination receiving unit 102, the clerk adds the insurance card number and the like to the medical application form received from the patient. The reading device 10 detects the added matter as handwriting data and sends it to the central processing unit 104. Host computer 10 of central processing unit 104
4a performs character recognition based on the transmitted handwriting data, and returns the recognized character data to the initial consultation receiving unit 102. The recognition characters are displayed on the computer 102a of the initial examination reception unit 102.

After that, the clerk of the initial examination receiving unit 102 operates the computer 102a to register the patient (S101). The host computer 104a of the central processing unit 104 assigns a new ID to the patient and stores this ID in the database 104b. Further, the host computer 104a saves the insurance number of the insurance card and the like in the database 104b (S102) and sends the data of the new medical examination ticket to the first consultation receiving unit 102. The computer 102a of the first consultation reception unit 102 issues a new medical ticket based on the medical ticket data (S103). Data such as an ID is recorded on the magnetic stripe attached to the medical ticket. An IC card may be used as the medical ticket instead of the magnetic card.
In this case, a lot of information such as medical history can be recorded on the medical ticket.

The patient receives the medical examination ticket from the initial examination receiving unit 102 and brings it to the examination unit 105 for reception.
The clerk or the nurse receives the medical ticket from the patient and causes the card reader to read the medical ticket (S107). The card reader sends the ID read from the medical ticket to the host computer 104a, and the host computer 104a sends the ID.
Various information regarding the information is returned to the consultation unit 105. The clerk or the like in the examination unit 105 confirms whether or not the returned information is correct (S108),
In particular, information regarding medical insurance is confirmed (S109). If there is no problem as a result of the confirmation, the clerk or the like hands the medical ticket or the like to the doctor in the examination unit 105 (S110).

When the patient's examination order comes, the patient enters the examination unit 105 and sits in front of the doctor. The computer 105a and the reading device 10 are installed in front of the doctor, and his / her signature is written on the chart placed on the reading device 10. The reading device 10 detects the handwriting of the signature as handwriting data and sends it to the host computer 104a. The host computer collates the handwriting data with the handwriting data that has already been registered, and when it is determined that they are the same person, the host computer opens the medical information file of the patient. Then, the host computer transfers the medical information data in the medical information file to the computer 105a.
Send to The medical information of the patient is displayed on the display of the computer 105a (S114), and the doctor can examine the patient while viewing the medical information on the display (S115).

While the doctor is conducting medical examination, the reading device 10
The chief complaint, treatment, prescription, etc. are entered on the chart placed on the table (S116). The reading device 10 detects handwriting such as characters and figures on the chart as handwriting data and sends it to the host computer 104a. Host computer 104
Among the transmitted handwriting data, a performs character recognition on the handwriting data in the character field. The handwriting data in the image field is converted into image data that is a function of the coordinate axes. These handwriting data, recognition character data,
Image data is associated with ID and database 1
Stored on 04b.

At the same time, these data are stored in the computer 1.
The recognition characters, images, etc., which are transmitted to the personal information 05a and are entered in the medical record are displayed on the display. In addition, the doctor fills in a prescription, an examination application form, etc., if necessary. The handwriting data of the characters written on these prescriptions and inspection application forms are similarly detected by the reading device 10 and processed by the host computer 104a. When the doctor confirms these displays and determines that there is no error, he / she inputs the fact to the computer 105a.

The operator may be prompted to confirm the entered character only when the character recognition of the input handwriting data is impossible or is likely to be erroneously recognized. That is, after the doctor completes the medical items in the medical chart, the doctor or the operator may use the computer 105a.
Hit the input key (Enter key) on the keyboard (instead of the Enter key, you may enter a symbol in the prescribed column of the chart). Then, the host computer 104a
However, if the handwriting data that cannot be recognized or is erroneously recognized is detected from the input handwriting data, the buzzer or the like is used to notify the operator of that fact and the characters based on the handwriting data are imaged. As shown on the display. Then, the operator can input accurate characters to the computer 105a while comparing the characters on the display and the characters on the chart.

Alternatively, the abbreviations of the disease name and the drug name may be registered in the database 104b as a conversion table, and the abbreviations described in the medical chart or the like may be converted into formal names by using the conversion table at the time of character recognition. As a result, it is possible to shorten the time required to fill in the medical record and the like.

After the medical treatment is completed, the clerk or the like in the medical examination unit 105 confirms the completed medical record, prescription, examination application form, etc. (S118), and accepts an appointment for the next medical treatment (S11).
9). The host computer 104a is the database 1
By referring to the reservation data on 04b, it is determined whether the reserved medical treatment at the date and time desired by the patient is possible.

The completed medical record or the like is stored in the medical record storage unit 103 (S120). A bar code is attached to each chart, and the operator inputs the bar code and the patient ID into the host computer 104a. After such input work, the medical records are collected for each medical treatment day and stored in the medical record storage unit 103. At a later date, if the collation is required, the operator inputs the patient ID into the host computer 104a, and the bar code related to the patient ID is displayed on the display. The operator then uses the barcode to store the chart storage unit 10
After grasping the storage location in 3, the chart storage unit 10
Take out the desired chart from 3. In this way, the operator can quickly find a desired medical record from the medical record storage unit 103.

When the patient needs the examination, the patient receives the medical ticket and the examination application form from the reception of the examination unit 105, and enters the examination unit 106 or the like. Characters and the like written on each slip such as an inspection slip, an injection slip, and a surgery slip are written as handwriting data in the medical information file of the patient ID. In this way, when the medical examination and the examination are all completed, the patient submits the medical ticket and the prescription to the payment window unit 111. When the clerk in the payment counter unit 111 causes the card reader to read the ID of the medical ticket, the ID
Is transmitted to the host computer 104a. Then, the host computer 104a opens the medical information file of the patient based on the ID and calculates the billing amount. The billed amount is displayed on the computer 111a of the payment window unit 111 (S121). The clerk charges the displayed charge amount to the patient, receives the medical expenses from the patient, and then performs the deposit process (S122). The printer of the computer 111a outputs a medicine voucher and a receipt, and these are delivered to the patient together with the medical ticket.

On the other hand, the prescription information is sent from the host computer to the computer 112a of the pharmacy unit 112. The pharmacist mixes the medicine while looking at the prescription information displayed on the computer 112a, and hands the medicine to the patient in exchange for the medicine voucher. In this system, since all medical information data for one patient is stored as one medical information file, the doctor can always keep track of the medicines given to the patient in other departments. Therefore, even if a drug is administered from multiple departments, it is possible to avoid a combination of drugs that causes side effects. In this way, the patient leaves the hospital after receiving the drug from the pharmacy unit 112. With the above, all the processing relating to the outpatient treatment of the patient is completed.

When the patient comes back at a later date, the patient causes the coming-back reception terminal 113 to read the ID of the medical ticket (S1).
04). The host computer 104a opens the medical information file of the patient based on the ID and confirms whether or not the patient is a returning patient (S105). When it is confirmed that the patient is a returning patient, the returning reception terminal 113 displays a message to that effect. After receiving the medical ticket, the patient completes the reception at the examination unit and enters the examination unit 105.

In the medical treatment for the returning patient (S11
3 to S116), the doctor calls the medical information file related to the patient ID from the database 104b on the computer 105a and displays a list of information names on the display. When the doctor selects the desired information from the displayed list, the host computer 104a sends the information of the selected information name to the computer 105a. For example, when a doctor selects a test result, the test result is displayed on the computer 10.
It is displayed on 5a, and the doctor can treat the patient while seeing this display.

The medical examination result thus obtained is recorded in a new medical chart different from the medical chart used in the initial examination. At this time, the handwriting data detected by the reading device 10 is transmitted to the host computer 104a, and character recognition is performed by the host computer 104a. The recognition character string is written in the medical information file related to the patient ID and added to the already saved medical chart information. When the medical information file is retrieved at a later date, information on a plurality of medical records is output in the input order (time stamp order).

Next, the processing in the appointment medical examination will be described.
The patient who has booked the medical treatment can receive the medical examination by directly submitting the medical ticket to the medical examination unit 105. That is, when the patient submits the medical ticket to the reception of the examination unit 104, the clerk or the like causes the card reader to read the medical ticket (S111). Then, after the medical information of the patient is confirmed (S112), the medical examination of the patient is performed as described above (S113-).

(Voucher Design Processing) The slip design processing will be described with reference to FIG. In the medical information input system according to the present embodiment, it is possible to design various slips such as charts and prescriptions. The slip can be designed using a terminal connected to the host computer 104a.

First, the operator inputs the size of the slip to be created into the terminal using the keyboard (S20).
1). Further, the operator instructs the host computer 104a with the slip items, such as the patient name, patient address, and insurance policy number (S202), and the digit number and size of each item (S203). The outline of the specified size slip is displayed on the display, and the operator specifies the position of each item while looking at this screen (S204). Since the actual voucher is displayed on the display, the operator can easily design the voucher.

Next, the operator determines the attributes of each item (character box size, inter-character distance, character type, etc.) (S205) and the check contents (S206) of each item. The check contents of each item include a master existence check, a range check, and a check digit check. The master existence check determines whether or not the recognition result character string of the target item (field) exists in the code master file designated in advance. That is,
If there is an unexpected character in the recognition result character string of each item, an error is output. When an error is output in the recognition processing stage, the recognized character can be corrected.

The range check determines whether or not the numerical value of the recognition result character string is within a predetermined range of maximum and minimum values, and outputs an error if the numerical value is out of the range. Therefore, it is premised that the characters to be range checked are numerical values.

The check digit check is intended to determine the remainder of the numerical value in the target recognition result character string divided by a certain value, and to judge the numerical error based on this remainder.

When the form of the slip is designed by the above processing, the designed slip is displayed on the display (S
207). The operator looks at this screen and determines whether or not the desired slip is designed (S208), and repeatedly executes the processing of S201 to S207 until the desired slip is designed. When the design of the desired slip is completed (S
If YES in 208), the image representing the artwork of the designed slip and the parameter representing the artwork are printed out from the printer 21d (S209). Therefore, it is possible to print a large amount of slips by using the image of the artwork and the artwork parameters. Further, the data representing the format of the slip, the data representing the attributes, and the like created by the above-described processing are given to the reading device 10.

When a medical information database is already installed in the hospital, it is possible to install the medical information input system according to this embodiment while using the existing database. However, if the format of the data record (for example, the data array) in the existing database is different from the format of the data record according to the present embodiment, it is necessary to match the two. In such a case, it is desirable to perform the following processing when designing the slip.

For example, as shown in FIG. 19, item A
Suppose a slip with ~ E is designed. Usually, the data for one voucher, that is, the data of items A to E are collected and stored as one record in the database. However, when the record of the existing database has the data array as shown in the lower part of FIG. 20, it is necessary to rearrange the data of the items A to E according to the array. Therefore, in the slip design process according to the present embodiment, the output format of the data record can be designated. That is, when the operator designates the data array of items A to E on the display, the input data array (upper part of FIG. 20) is automatically converted to the data array of the existing database (lower part of FIG. 20). . As a result, the medical information input system according to the present embodiment can be installed in a hospital while maintaining compatibility with existing databases. In addition to specifying the data array,
Of course, the data length (number of character digits), character type, and attribute can be specified.

(Initial Examination Application Form Entry Process) FIG. 14 shows a flowchart of the initial examination application form entry process. First, the terminal 101 for first-visit patients determines whether or not the sensor 1a is turned on, that is, whether the patient is positioned in front of the terminal 101 for first-visit patients (S301). When the sensor 1a is off (NO in S301), the terminal 10 for the first visit patient
1 continues to execute the determination of S301 until the sensor 1a is turned on. When the patient is located in front of the terminal 101 for the initial examination patient and the sensor 1a is turned on (YES in S301
In S), the terminal 101 for first-visit patients determines whether or not the switch 1b is turned on (S302).

If the pen 1c is not lifted by the patient from the pen holder and the pen 1c is in the pen holder, the switch 1b remains off (S302).
NO). In this case, the terminal 101 for the first visit patient continues to monitor the states of the sensor 1b and the switch 1c (S
301, S302). On the other hand, when the patient lifts the pen 1c, the switch is turned on (YES in S302).
The processing from S) to S303 is executed.

At S303, the terminal 101 for the first-visit patient
Determines whether or not the patient has entered characters in the initial examination application form, that is, whether or not the tip of the pen 1c has come into contact with the surface of the reading device 10. Here, the patient picks up the slip from the terminal 101 for the first-visit patient and reads the slip.
Suppose it is placed on top. When the patient brings the tip of the pen 1c into contact with the voucher, the reading device 10 detects that characters and the like have begun to be written on the initial examination application form (Y in S303).
ES). Then, the terminal 101 for the first-visit patient resets the timer indicating the blank time of the character (S304). This timer counts up over time,
This indicates the time since the tip of the pen 1c was separated from the initial application form. In S305, the reading device 10 reads the coordinates (X coordinate, Y coordinate) of the tip of the pen 1c, and temporarily stores these coordinates as handwriting data in the memory of the reading device 10.

Subsequently, the terminal device 101 for first-visit patients determines whether or not a mark has been entered in the cancellation column of the initial application form, and if not (NO in S306), S307 and thereafter. Continue processing. When the mark is entered in the cancellation column (YES in S306), the terminal device 101 for the first-visit patient stops the detection of the handwriting data and returns to the standby state (S301).

On the other hand, if no mark is entered in the cancellation column (NO in S306), the patient terminal device 101 determines whether or not the mark is entered in the confirmation column, that is, the patient has entered all necessary items. After that, it is determined whether or not the confirmation column is marked (S307). If no mark is entered in the confirmation column (YES in S307), it is expected that the patient will continue to enter characters in the slip, so the terminal 101 for the first-visit patient returns to S303, and the handwriting data. Continue to detect. While the patient fills in characters, etc. on the initial consultation application form, the terminal 101 for the initial consultation patient resets the timer (S30
4) The handwriting data detection (S305), the cancellation column and the confirmation column check (S306, S307) are continuously executed.

In this way, when the patient completes all necessary items in the initial examination application form and puts a mark in the confirmation column, the terminal 101 for the initial examination patient displays the handwriting data stored in the reading device 10 at the center. It transmits to the processing unit 104 (S308), and returns to a standby state (S301). In addition to the handwriting data, the data (time stamp) representing the transmission time and the data of the terminal number of the first-examined patient terminal 101 are transmitted to the central processing unit 104.

On the other hand, in step S303, when the terminal 101 for the first-visit patient determines that the initial examination application form has no characters, that is, if the tip of the pen 1c is not in contact with the initial examination application form, The patient terminal 101 counts up (increments) the timer described above (S309). When the timer has not reached the predetermined value (NO in S310), the terminal 101 for the first-visit-patient determines again whether or not characters are entered in the application form for the first-visit (S3).
03). If the patient notices a mistake in the middle of writing the letter on the initial medical examination application form and leaves the initial medical examination application form as it is, the time when no character is entered exceeds the predetermined value.
The timer reaches a predetermined value (YES in S310).

After that, the terminal 101 for the first-visit patient determines whether or not the sensor 1a or the switch 1b is turned off (S311). That is, the patient is the terminal 1 for the first visit patient.
When it is separated from 01 or when the patient returns the pen 1c to the pen holder (YES in S311), it is determined whether or not at least the name and address are entered on the initial examination application form (S312). As a result, the terminal 101 for the first visit patient is
If it is determined that the name and address are entered (S312)
If YES, the handwriting data is transmitted to the initial examination receiving unit 102 (S308). That is, even if the cancellation column and the confirmation column are not marked, as long as the name, address, etc. are entered, these handwriting data are treated as valid. Therefore, even if the patient forgets to mark the cancellation and confirmation fields, he / she can still be called at the counter. However, as will be described later, if the patient still does not appear at the counter within a predetermined time after being called, it is possible that the initial medical examination application form has been discarded, etc. Is erased. On the other hand, when it is determined in S312 that the name and the like are not described, the terminal 101 for the first-visit-patient returns the process to S301, and waits for the patient to come.

As a modification of the slip entry process described above, a process in which step S312 is not performed may be considered.
That is, when the time is up without a mark in either the cancellation column or the confirmation column, the detected handwriting data may be treated as invalid.

Furthermore, in the above-mentioned processing of S306,
When an incorrect character or the like is written on the slip, the cancel processing shown in FIGS. 8 and 10 may be performed as described above. Further, the above-mentioned processing is not limited to the initial medical examination application form, and can be applied to all voucher filling processing in the hospital.

(Window Processing) FIG. 15 shows a flowchart of the window processing. This process is mainly performed by the first visit reception unit 1
02, which is executed by the central processing unit 104. First, the central processing unit 104 receives handwriting data and the like from the terminal 101 for the first-visit patient (S40).
1) Determine the time stamp added to the handwriting data (S402). Then, the central processing unit 104 transmits the handwriting data of the unprocessed slips to the initial consultation receiving unit 102 in the order of the oldest time stamps. First consultation reception unit 10
Unprocessed slips are displayed on the second computer 102a in the order of oldest time stamps (S403). The slip displayed on the computer 102a is an image image reproduced based on the handwriting data. However, the computer 1 also includes a recognized character string (text data) based on handwriting data.
It may be displayed on 02a.

The initial examination receiving unit 102 automatically selects the oldest time stamped item from the displayed slips (S404). The clerk may select a slip from the slips displayed on the computer 102a. The initial examination reception unit 102a performs character recognition based on the handwriting data of the name portion of the slip, and displays the patient name, which is the recognition result character string, on the guide display 2d to call the patient at the counter (S405). In addition,
Multiple patient names may be displayed on the guidance display 2d, in which case the patient can infer when to be called. The patient name may be called up by a voice synthesizer (not shown).

When the patient does not appear at the counter after a lapse of a certain time after calling the patient (NO in S406)
It is possible that the patient left the building with the slip. Therefore, in such a case, the next order slip is selected (S407), and the order of slip processing for the patient who did not appear at the counter is put back. When a patient whose order has been delayed appears at the counter later, the clerk can call the handwriting data of this patient from the memory and perform the slip processing. However, the handwriting data of the patient called several hours ago (for example, 6 hours) is automatically deleted from the database 104b of the central processing unit 104. This can prevent the memory from overflowing due to a large amount of handwriting data.

On the other hand, when the patient appears at the counter (S406
In YES), the clerk receives the slip from the patient and places it on the reading device 10. At this time, it is desirable to place the slip at a predetermined position of the reading device 10. By doing so, the host computer 104 can accurately determine in which part of the slip the additional matter is described by the clerk.

The clerk fills out necessary items (for example, insurance policy number) outside the thick frame of the slip on the reading device 10 and supplements the omission in the thick frame of the slip (S408).
The reading device 11 detects the coordinate change of the pen tip as handwriting data (S409) and stores it in the memory. Then, the computer 102a corrects the coordinate value of the handwriting data input by the clerk to generate handwriting data composed of relative coordinates with respect to the reference coordinates (for example, the coordinates of the lower left corner) of the slip. Since the slip is placed at a position determined by the clerk on the reading device 10, the relative coordinates can be easily calculated.

Further, the initial examination receiving unit 102 corrects the coordinate value of the handwriting data input by the patient by the following procedure. First, the initial examination reception unit 102 uses the first character 12a and the last character string 12b of the character string of the slip 4.
Then, the respective coordinates are obtained and a straight line passing through both coordinates is calculated (see FIG. 9). By obtaining the inclination θ between this straight line and the reference line, the inclination of the slip 4 with respect to the reading device 10 can be obtained. Further, the position of the slip 4 can be calculated by the coordinates of the leading character 12a and the trailing character 12b. Therefore, desired data (handwriting data representing a patient name, etc.) can be accurately extracted from the handwriting data, and the patient does not need to pay attention to the position and angle of the slip on the reading device 10.

The two types of handwriting data thus corrected (the handwriting data of the patient and the handwriting data of the clerk) are combined with each other, and one handwriting data corresponding to one voucher is generated. Then, the host computer 104a
Performs character recognition based on this handwriting data (S41
0). The character recognition procedure will be described in detail later, but the outline thereof will be described here. First, the characters that can be used for character recognition are determined in advance and these characters are input to the reading device 10. The characters written on the reading device 10 are used as reference handwriting data in the database 10
It is stored in 4b. Then, the reference handwriting data most similar to the handwriting data to be recognized is searched, and the character corresponding to the reference handwriting data is output as the identification result. Note that image data (data including a coordinate function) may be generated based on the handwriting data, and character recognition based on the image data may also be performed. As described above, the recognition rate can be improved by performing character recognition using both the handwriting data and the image data.

The recognized character string is displayed on the computer 102a together with the image of the slip reproduced based on the handwriting data.
Displayed above. Since the clerk can detect the misrecognition by comparing these, it is possible to prevent the occurrence of the accident.

Character string based on handwriting data (patient name, etc.)
If is recognized, the host computer 104a performs a slip process (S411). First, the host computer 10
4a identifies the type of slip. To identify the type of slip,
For example, the clerk may instruct the computer 102a, but the judgment may be made based on the items described in the slip.

After the type of slip is identified, the host computer 104a executes a process according to the type of slip (S411). For example, when the voucher is the initial examination application form, the host computer 104a performs processing such as registration of the patient ID. When the slip processing is completed, the host computer 104a stores these image data, handwriting data,
Database 1 for time stamp data, patient ID, etc.
It is stored in 04b (S412). The window processing described above is not limited to the processing in the initial examination receiving unit 102, but the examination unit 105 and the block receiving unit 1 can be used.
09, the payment window unit 111, and the pharmacy unit 112.

(Character Recognition Processing) FIG. 16 shows a detailed flowchart of the character recognition processing.

In this figure, the host computer 10
4a extracts the effective area of the handwriting data, that is, the data area during the period when the tip of the pen 1c is in contact with the digitizer 10a (S501). Next, the computer 20
Performs normalization on the effective area of the handwriting data to keep the range of the handwriting data within a certain range (S502). Orthogonal function transformation such as Hadamard transformation, Kahnen-leve transformation, and cosine transformation is performed on the effective area of this handwriting data (S503), and the handwriting data represented by the time axis (t) is represented by the orthogonal axis (s) It By expressing the handwriting data on the orthogonal axis in this manner, it becomes possible to extract the characteristic portion of the handwriting.

The handwriting data represented by the orthogonal axis (s) is the function G
[X (S), Y (s)] is converted into a value g representing the feature (S504). On the other hand, sample values g ₁ , g ₂ , g ₃ , g ₄ , ... Of characters to be recognized such as numbers and alphabets are prepared in advance. Then, the sample value closest to the value g is searched (S505), and the character corresponding to this sample value is obtained as the recognition result (S506).

Performs various data checks on the recognized character (S507). For example, if there is a character other than a number in the amount column (data field), the result of the data check will be an error. By performing such a data check, it is possible to detect erroneous recognition of characters.

As a result of the data check of the recognized character, if the erroneous recognition is detected (NO in S508), the host computer 104a determines the next candidate character string (S50).
9), data check is performed for this character string (S5)
07). On the other hand, if no erroneous recognition is detected (S50
In 8), the recognized character is confirmed. Medical information data is generated based on the recognized characters thus obtained.

Note that the doctor's signature authentication process at the time of filling in the medical record is performed according to the above-described recognition process.
That is, the sample value of the doctor's signature detected by the reading device is registered in the database 104b in advance as g. Then, a difference Δg between the sample value g ′ of the doctor's signature and the registered sample value g at the time of writing the chart is calculated. If the difference Δg is less than or equal to a predetermined threshold value, the doctor's signature is judged to be valid. If the signature is not valid (when a person other than the registered doctor opens the medical file and tries to create a medical record), the host computer 104a sends a message to the computer 10.
It is displayed on 5a and access to medical files is prohibited.
