FIG. 9 is a diagram schematically showing an example of a situation in which the syringe 40 according to the first embodiment is placed or taken out on the mounting surface 6. As shown in FIG. 9, the syringe 40 includes a barrel 41 and a plunger 49. The barrel 41 has a cylindrical accommodating portion 42 for accommodating the chemical solution inside. A chemical liquid inlet / outlet 49a is provided at the tip of the barrel 41. An opening 46 is provided at the rear end of the barrel 41. A scale 42a is attached to the outer peripheral surface of the barrel 41.

A gasket portion 44 that slides on the inner peripheral surface of the barrel 41 is provided on the tip end side of the plunger 49. In the scale 42a, a scale overlapping the tip surface 43 of the gasket portion 44 is attached so as to indicate the amount of the chemical solution contained in the barrel 41.

For example, in FIG. 9, the scale of the scale 42a overlapping the tip surface 43 of the gasket portion 44 is 10 ml (ml: milliliter), and in this state, 10 ml of the chemical solution is contained inside the barrel 41. The doctor administers the drug solution while holding the syringe 40. At the time of administration, the doctor moves the plunger 49 in the syringes 40 so as to push it toward the drug solution inlet / outlet 49a. As a result, the drug solution extruded from the barrel 41 is administered to the patient via the drug solution inlet / outlet 49a. In the scale 42a, the amount of the drug solution contained in the barrel 41 indicated by the scale overlapping with the tip surface 43 of the gasket portion 44 after administration and the amount of the drug solution contained in the barrel 41 indicated by the scale overlapping with the tip surface 43 before administration. The difference from the amount of the drug solution is the dose of the drug solution. An RF tag 300 is attached to the syringe 40, for example, on the outer peripheral surface of the barrel 41. The mounting position of the RF tag 300 on the syringe 40 may be any position as long as it can communicate with the RF reader / writer 5 with the syringe 40 mounted on the mounting surface 6, and is limited to the outer peripheral surface of the barrel 41. Not done.

The doctor places the syringe 40 on the mounting surface 6 while grasping it, or removes it from the mounting surface 6. When the placement is detected, the display 13 and the indicator 15 display the drug information (drug ID 154 and the like) read from the RF tag 300 by the RF reader / writer 5, and the detected weight value 152, respectively. Further, when the placement is detected, when the collation unit 62 detects the collation match, the display 13 and the indicator 15 display the collation match drug information (drug ID 154 and the like) and the weight difference 157, respectively. In such a display, the indicator 15 may have a different display mode so that it can be identified whether the displayed value is the weight value 152 or the weight difference 157.

FIG. 10 is a diagram schematically showing another example of a situation in which the syringe 40 according to the first embodiment is placed or taken out on the mounting surface 6. For example, in FIG. 10, the scale of the scale 42a overlapping the tip surface 43 of the gasket portion 44 is 7 ml, and in this state, 7 ml of the chemical solution is contained inside the barrel 41. In this embodiment, the syringe 40 can be used for one-shot administration. More specifically, when a drug is administered in a hurry in order to cope with a sudden change in a patient in intensive care such as ICU, the doctor takes out the syringe 40 from the mounting surface 6 and operates the syringe 40 to treat the patient with the drug. Is administered in one shot. Since such one-shot administration is on-site administration, in order to reliably record the dose on the electronic medical record 230, in the present embodiment, the doctor places the syringe 40 on the mounting surface 6 before and after the one-shot administration. By placing it on the top, it is possible to automatically record the administered drug information 153 and the weight difference 157, that is, the dose, in the electronic medical record 230 for each administration. For example, when a doctor takes out the syringe 40 placed on the mounting surface 6 of FIG. 9 and performs one-shot administration, and then places the syringe 40 on the mounting surface 6 as shown in FIG. 10, the administration is performed. The given drug information 153 and the weight difference 157, that is, the dose, are displayed on the display 13 and the indicator 15 of FIG. 10, respectively, and the time of administration 151, the drug information 153, and the weight difference 157 (dose) are linked. It is attached and automatically recorded in the electronic medical record 230.

According to the displacement of the position of the tip surface 43 of the syringe 40 in FIGS. 9 and 10, the dose by one-shot administration is 3 ml (10 ml-7 ml = 3 ml). When the weight difference 157 is used, the dose can be calculated as a volume according to (weight difference 157 / specific density 155). In addition, the tying portion 64 is the first time (time “T1” in FIG. 8 before administration) when it is detected that the syringe 40 is placed on the mounting surface 6 as the administration time to be tie. The second time (time in FIG. 8 after administration) when it was detected that the syringe 40 was returned and placed on the mounting surface 6 after the syringe 40 was taken out from the mounting surface 6. The second time of T2 ") is set. The associated administration time is not limited to the above-mentioned second time, and may be the first time.

(flowchart)
FIG. 11 is a flowchart showing an example of the process according to the first embodiment. The processor 101 detects whether or not the target (syringe 40) is mounted on the mounting surface 6 as the mounting / taking-out detecting unit 60 (step S3). When it is detected that the target is not placed (NO in step S3), the process of step S3 is repeated.

When it is detected that the object has been placed (YES in step S3), the write / read unit 61 responds to the detection value 70 from the placement / take-out detection unit 60 indicating "placement". , Time 151 from timer 104, weight value 152 from balance I / F20 and drug information 153 from communication I / F19 to generate record 156 and write (store) it in table 105 (steps S5, S7). , S11). At this time, the processor 101 displays the drug ID 154 and the weight value 152 of the drug information 153 on the display 13 and the indicator 15, respectively (step S9).

The processor 101 searches the table 105 as the collation unit 62 (step S13). More specifically, the processor 101 indicates the drug ID 154 of the drug information 153 acquired in step S7, indicating a time 151 corresponding to a period of a predetermined length that goes back to the time 151 clocked in step S5. The record 156 is collated with each drug ID 154 (step S13). The period of the predetermined length in step S13 is, for example, a time of a length determined based on the required time of one-shot administration, and more specifically, the syringe 40 is placed on the mounting surface 6 before the one-shot administration. This corresponds to the time required for the syringe 40 to be returned to the mounting surface 6 and mounted after one-shot administration after being taken out.

As a result of the collation, the processor 101 determines whether or not the drug ID 154 of the drug information 153 read from the RF tag 300 of the syringe 40 and one or more records 156 having the collation matching drug ID 154 are searched in step S7. Determination (step S15).

If it is determined that the record 156 having the matching drug ID 154 was not searched (NO in step S15), the process returns to step S3.

On the other hand, when it is determined that one or more records 156 having the matching drug ID 154 have been searched (YES in step S15), the processor 101 detects the weight difference 157 as the weight difference detecting unit 63 (step S17). , S19). More specifically, the processor 101 has the most recent time 151 (for example, the time of FIG. 10) with respect to the time 151 (for example, time “T2”) of step S5 among the one or more records 156 detected in step S13. One record 156 indicating “T1”) is specified (step S17).

The processor 101 serves as a weight difference detecting unit 63 to specify the weight value 152 measured at the time “T2” (weight value 152 measured in step S3) and the weight value 152 measured at the time “T1” (specified in step S17). The weight difference 157 is acquired from the weight value 152) of the recorded record 156 (step S19).

The processor 101 associates the drug information collated and matched by the search in step S13 with the weight difference 157 acquired in step S19 and the time 151 (for example, the time “T2”) as the association unit 64. Information 72 is output (step S21). The transfer unit 65 transfers the association information 72 from the association unit 64 to the electronic medical record server 2 in order to record it in the electronic medical record 230 (step S23).

According to the process described above, for each one-shot administration, the dose corresponding to the weight difference 157 before and after the one-shot administration is associated with the administration time (the above time “T2”) and the drug information 153. , Can be recorded in the electronic medical record 230.

(Example of electronic medical record 230)
FIG. 12 is a diagram schematically showing an example of 230 of the electronic medical record according to the present embodiment. The electronic medical record 230 has the medical record information 232 of the patient for each patient ID that identifies the patient. The medical record information 232 includes management information 233, administration information 234 showing the history of drug administration, and vital information 235 including, for example, blood pressure and body temperature.

The management information 233 includes drug information of the administered or administered drug and a staff ID that identifies the administered or administered physician.

The administration information 234 provides a weight difference of 237, a dose of 238, and an integrated dose of 239 in association with one or more times 236 indicating the time when the drug indicated by the drug information indicated by the management information 233 was administered, and each time 236. include.

The CPU 211 of the electronic medical record server 2 stores the administration information 234 based on the received association information 72 each time the association information 72 is received from the information processing device 1. More specifically, the CPU 21 has the time 151 and the weight of the received association information 72 in the chart information 232 having the management information 233 matching the drug information 153 (drug ID 154 and specific gravity 155) of the association information 72. The difference 157 is recorded as the time 236 and the weight difference 237, respectively, and the dose 238 is calculated and recorded from the weight difference 237 and the specific gravity 155 of the drug, and the integrated dose 239 of the dose 238 is calculated. Record. The integrated dose 239 is calculated as the sum of the dose 238 based on the association information 72 and the dose 238 based on one or more association information 72 received and recorded prior to the association information 72. Will be recorded. Vital information 235 indicates vitals (blood pressure, body temperature, etc.) measured in synchronization with time 236 of administration information 234.

As a result, in the patient's medical record information 232, information related to the administered drug (administration drug ID 154, administration time 236, dose 238 and integrated amount 239 at that time, etc.) is provided in the electronic medical record for each one-shot administration. It can be automatically recorded in 230.

Embodiment 2.
In the first embodiment described above, the dose 238 of the drug is obtained from the weight difference 237 of the syringe 40 before and after administration. In contrast, in Embodiment 2, a dose of the drug 238 is obtained by deriving the volume of the contained drug solution from images taken by the syringe 40 before and after administration. The camera 21a for imaging is attached so that the entire syringe 40 mounted on the mounting surface 6 can be arranged in the imaging field of view.

FIG. 13 is a diagram schematically showing a hardware configuration of the information processing apparatus 1a according to the second embodiment. The information processing device 1a includes a camera I / F 20a to which the camera 21a is connected, in addition to the configuration of the information processing device 1 of FIG. The camera I / F 20a causes the camera 21a to perform an imaging operation in accordance with an imaging command 73 from the control unit 100. The camera I / F 20a stores the captured image output from the camera 21a by the imaging operation in the image buffer 20c, performs predetermined processing such as brightness adjustment on the captured image stored in the image buffer 20c, and performs the captured image data 20b. Is output as. Further, the information processing apparatus 1a stores the table 105a, which will be described later, in place of the table 105 shown in FIG. Since the other parts of the configuration of the information processing apparatus 1a are the same as those shown in FIG. 3, the description will not be repeated.

FIG. 14 is a diagram schematically showing an example of a functional configuration for processing information on drug administration by a syringe according to the second embodiment. The processor 101 of the information processing apparatus 1a of FIG. 14 has a mounting / taking-out detecting unit 60a and a dose detecting unit 63a in place of the mounting / taking-out detecting unit 60 and the weight difference detecting unit 63 shown in FIG. , In addition to the configuration of FIG. 7, has an image processing unit 66. Since the other configurations of FIG. 14 are the same as those shown in FIG. 7, the description will not be repeated.

Based on the weight value 152 output from the balance I / F20, the mounting / taking-out detection unit 60a places the target (syringe 40) on the mounting surface 6 in the same manner as the mounting / taking-out detecting unit 60. It is detected whether or not the target has been removed or whether or not the target has been taken out from the mounting surface 6. When the mounting / taking-out detection unit 60a detects that the target is mounted on the mounting surface 6, the processor 101 outputs an image pickup command 73. The camera I / F 20a controls the camera 21a so that the image pickup operation is performed according to the image pickup command 73.

The camera I / F 20a outputs captured image data 20b based on the captured image from the camera 21a. The image processing unit 66 extracts a predetermined feature amount from the captured image data 20b output by the camera I / F 20a, and matches the extracted feature amount with the predetermined pattern to match the liquid level portion in the syringe 40 from the captured image. An image, that is, a partial image showing the position of the tip surface 43 of the gasket portion 44 on the scale 42a is specified, the position of the specified partial image on the scale 42a is converted into a capacitance value 152a, and the converted capacitance value 152a is output. As a result, the image processing unit 66 detects the volume value 152a, which represents the volume of the drug (drug solution) contained in the syringe 40. As a method for converting the position of the liquid level into the volume value 152a, a method for converting by a predetermined calculation formula, a method using a table lookup, or the like can be applied.

FIG. 15 is a diagram schematically showing an example of the contents of the table 105a according to the second embodiment. The table 105a stores the capacity value 152a in place of the weight value 152 of the table 105 of FIG. Since the other information in the table 105a is the same as that in the table 105 in FIG. 8, the description will not be repeated. The writing / reading unit 61 generates a record 156 in which the capacity value 152a output from the image processing unit 66 is associated with the drug information 153 read from the time 151 and the IC tag 300, and the generated record 156 is generated. Store in table 105a.

By performing the same collation process as in the first embodiment, the collation unit 62 identifies and identifies the record 156 (for example, the record 156 in the thick frame of FIG. 15) having the drug ID 154 whose collation result indicates a match. The capacity value 152a of the recorded record 156 is read out and output to the dose detection unit 63a. The dose detection unit 63a calculates the difference between the volume value 152a from the collating unit 62 and the volume value 152a from the image processing unit 66, and detects the calculated difference as the dose 238 (unit: ml). When the collation result 71 of the collation unit 62 indicates “collation match”, the association unit 64 receives the drug information 153 input from the communication I / F 19 (that is, the collation match drug information 153) and the dose detection unit 63a. By associating with the dose 238, the associating information 72a is generated and output. The transfer unit 65 transmits (transmits) the association information 72a from the association unit 64 to the electronic medical record server 2 via the network I / F 110 in order to record the association information 72a in the electronic medical record 230.

FIG. 16 is a diagram schematically showing an example of a situation in which the syringe 40 according to the second embodiment is placed or taken out on the mounting surface 6. In FIG. 16, in the shield case 3, the camera 21a is attached so that the entire object (syringe 40) mounted on the mounting surface 6 can be imaged. The mounting position of the camera 21a is not limited to the position shown in FIG. 16 as long as the entire target (syringe 40) can be imaged.

FIG. 17 is a flowchart showing an example of the process according to the second embodiment. The flowchart of FIG. 17 adds steps S4a and S4b to the flowchart of the first embodiment of FIG. 11, and has steps S5a, S19a, and S21a in place of steps S5, S19, and S21. The processing of the other steps in FIG. 17 is the same as the processing shown in FIG. 11, and will be briefly described.

When the processor 101 detects that the target (syringe 40) is placed on the mounting surface 6 as the mounting / taking-out detection unit 60a (YES in step S3), the processor 101 outputs an imaging command 73, and the camera 21a captures images. An image is taken according to the command 73 (step S4a). The image processing unit 66 performs image processing on the captured image data 20b based on the captured image output from the camera 21a, and outputs a capacitance value 152a based on the processing result (step S4b).

When it is detected that the object has been placed (YES in step S3), the writing / reading unit 61 responds to the detection value 70 from the mounting / taking-out detection unit 60 indicating “mounting”. , The time 151 from the timer 104, the capacity value 152a from the image processing unit 66, and the record 156 associated with the drug information 153 from the communication I / F19 are generated and written (stored) in the table 105a (steps S5a, S7). , S11). At this time, the processor 101 displays the drug ID 154 and the capacity value 152a of the drug information 153 on the display 13 and the indicator 15, respectively (step S9).

The processor 101 searches the table 105a as the collation unit 62 (step S13). More specifically, the processor 101 indicates the drug ID 154 of the drug information 153 acquired in step S7, indicating a time 151 corresponding to a period of a predetermined length that goes back to the time 151 clocked in step S5. The record 156 is collated with each drug ID 154 (step S13). As a result of the collation, the processor 101 determines whether or not the drug ID 154 of the drug information 153 read from the RF tag 300 of the syringe 40 and one or more records 156a having the collation matching drug ID 154 are searched in step S7. Determination (step S15).

If it is determined that the record 156a having the matching drug ID 154 was not searched (NO in step S15), the process returns to step S3.

On the other hand, if it is determined that one or more records 156a having the matching drug ID 154 have been searched (YES in step S15), the processor 101 detects the dose 238 as the dose detection unit 63a (step S17). , S19a). More specifically, the processor 101 has one or more records 156 detected in step S13, which is the most recent time 151 (for example, the time “T2” in FIG. 15) in step S5. One record 156 indicating the time “T1” of 15) is specified (step S17).

The processor 101 is specified as a dose detection unit 63a as a volume value measured at time “T2” (capacity value 152a measured in step S3) and a volume value measured at time “T1” (specified in step S17). The dose 238, which is the difference from the volume value 152a) of the record 156a, is acquired (step S19a).

As the linking unit 64, the processor 101 links the drug information 153 collated and matched by the search in step S13, the dose 238 acquired in step S19, and the time 151 (for example, the time “T2”) to link the drug information 153. The attached information 72a is generated and output (step S21a). The transfer unit 65 transfers the association information 72a from the association unit 64 to the electronic medical record server 2 in order to record it in the electronic medical record 230 (step S23).

According to the process described above, the dose 238 can be obtained from the captured images before and after the one-shot administration for each one-shot administration, and the obtained dose 238 can be obtained at the time of administration 236 (time “T2” above). And the drug information 153 can be linked and recorded in the electronic medical record 230. As shown in FIG. 11, the electronic medical record 230 records the time of administration 236, the dose 238, and the integrated dose 239 for each one-shot administration.

In the second embodiment, the number of syringes 40 mounted on the mounting surface 6 is not limited to one, and may be a plurality. The drug ID 154 is printed on the tag of the syringe 40, for example, the tag attached to the surface of the syringe 40 or the surface of the RF tag 300. When the camera 21a images a plurality of syringes 40 mounted on the mounting surface 6, the captured image data 20b includes a partial image of the drug ID 154 printed on the tag of each syringe 40. The image processing unit 66 recognizes the drug ID 154 indicated by the partial image by performing image processing such as pattern matching on the captured image data 20b, and outputs a set of the drug ID 154 identified for each syringe 40 and the capacity value 152a. .. The writing / reading unit 61 and the collating unit 62 perform the search and collation of the table 105 described above for each set output from the image processing unit 66, that is, for each syringe 40 (each drug). Thereby, even when a plurality of syringes 40 are placed on the mounting surface 6, the dose 238 can be obtained for each syringe 40 (recognized drug ID 154).

(Other configurations of RF tag 300)
FIG. 18 is a diagram schematically showing another configuration of the RF tag 300 according to the present embodiment. In the first and second embodiments, the information processing device 1 (1a) stores the history information of drug administration for each syringe 40 (that is, for each drug) in the table 105 (105a) of the storage unit of the information processing device 1 (1a). However, the storage destination of the table 105 or 105a is not limited to the storage unit of the information processing apparatus 1 (1a). For example, the table 105 or 105a may be stored in the memory 331 of the RF tag 300 as shown in FIG. In FIG. 18, for the sake of explanation, a configuration in which a table 105 holding the weight value 152 of the first embodiment and a table 105a holding the capacity value 152a of the second embodiment are stored in the memory 331 of the RF tag 300 is configured. As shown, in reality, one of the table 105 and the table 105a may be stored in the memory 331.

When the history information of drug administration is stored in the memory 331 of the RF tag 300 provided in the syringe 40, the writing / reading unit 61 writes the time 151 and the weight value 152 (or the capacity value 152a) in the memory 331 in association with each other. The RF reader / writer 5 is controlled to send a write command for inserting. The RF tag 300 associates the received time 151 with the weight value 152 (or the capacity value 152a) and stores it in the table 105 (105a) of the memory 331 according to the write command received from the RF reader / writer 5. Further, the write / read unit 61 controls the RF reader / writer 5 to transmit a read command for reading from the memory 331 in association with the time 151 and the weight value 152 (or the capacity value 152a). The RF tag 300 associates the time 151 with the weight value 152 (or the capacity value 152a) from the table 105 (105a) of the memory 331 according to the read command received from the RF reader / writer 5, and has record 156 (or record 156a) having information. Is read and transferred to the information processing apparatus 1 (1a) via the RF reader / writer 5. As a result, the collation unit 62 of the information processing apparatus 1 (1a) performs a collation process on the information stored in the table 105 (105a) of the memory 331 of the RF tag 300, and detects the weight difference when the collation matches. Unit 63 and dose detection unit 63a detect a weight difference of 157 and a dose of 238, respectively.

In the present embodiment, the table 105 (105a) of the administration history information for each syringe 40 (for each drug) is held on the information processing apparatus 1 (1a) side, or on the RF tag 300 side of the syringe 40. Any of the configurations can be adopted.

In the above embodiment, the loading / unloading detection unit 60 uses the output of the electronic balance 21 to detect the loading or unloading of the syringe 40, but the device used for the detection is not limited to the electronic balance 21. For example, a method of detecting the presence or absence of an object (syringe 40) on the mounting surface 6 by a proximity switch may be used. Alternatively, by processing the image captured from the camera 21a on a frame-by-frame basis, the movement of the image, that is, the movement of the object (syringe 40) in the imaging field of view (movement amount (direction, distance), etc. of the movement) is detected, and the detection result is obtained. The placement or removal of the object may be detected based on the above.

In the present embodiment, the doctor places the syringe 40 on the mounting surface 6 after the administration even if the syringe 40 becomes empty as a result of administering all the drugs in the syringe 40. In the present embodiment, the processor 101, as the collation unit 62, indicates one or more records 156 indicating a time 151 corresponding to a period of a predetermined length that goes back to the time 151 clocked in step S5 of the table 105 (table 105a). It is collated with each drug ID 154 (step S13). In the present embodiment, since the period of this predetermined length is set as, for example, a time of a length determined based on the required time of one-shot administration, the processor 101 starts from the time 151 when the placement is detected. Immediately after, the elapsed time until the placement is detected is measured, the elapsed time is compared with the period of the predetermined length, and as a result of the comparison, when it is determined that the elapsed time exceeds the predetermined length period during the measurement. (That is, when the immediate placement is not detected even after the specified length period is exceeded), an alarm is output. The alarm output includes an output of an alarm sound prompting the placement of the syringe 40 via the speaker 17, a display via the display 13 of the drug ID 154 of the syringe 40 for which placement was not detected, and the like. The alarm output prompts the doctor to place the syringe 40 on the mounting surface 6 after the one-shot administration, even if the syringe 40 is emptied as a result of administering the entire drug. Therefore, the information processing apparatus 1 (1a) can surely acquire the dose information for each one-shot administration, ensure the accuracy of the information related to the drug administered to the patient, and the information recorded in the electronic medical record 230. The accuracy of can be maintained.

The information processing apparatus 1 and the information processing apparatus 1a are programs in which the processor 101 stores the functions provided by the respective units shown in FIGS. 7 and 14, respectively, in the storage unit (memory 102, HDD 24, memory card 23, etc.). However, some or all of these functions provided can be achieved by using a dedicated hardware circuit (for example, ASIC (application specific integrated circuit) or FPGA (field-programmable gate array)). It may be implemented. Further, these programs may be transferred to the information processing device 1 (1a) via the network 9 and stored in the storage unit, or the program read from the memory card 23 may be stored in the information processing device 1 (1a). It may be stored in a unit (memory 102, HDD 24, etc.).
