The medical pump 100 reads a data set stored in the communication device 300 from the communication device 300 attached to the syringe 200 attached to the medical pump 100.

The data set read by the medical pump 100 from the communication device 300 contains, for example, drug identification information. Here, the drug specific information is information that can specify a drug profile, for example, a drug code. The drug code includes, for example, a so-called HOT code consisting of a 13-digit control number.

The drug profile is a collection of setting information and the like when a drug is administered by the medical pump 100. The drug profile has setting information such as, for example, a reference administration rate, an upper / lower limit value of the administration rate, a drug code, and a drug color. A drug profile is a collection of multiple setting information about one drug. In addition, for example, a drug library is a database of thousands of drug profiles.

The medical pump 100 may store a drug library containing a plurality of drug profiles.

For example, when the data set read by the medical pump 100 from the communication device 300 contains the drug identification information, the medical pump 100 is based on the drug profile corresponding to the drug identification information contained in the data set. , Information on administration (hereinafter, also simply referred to as "administration information") can be set.

When the syringe 200 is a prefilled syringe, a communication device 300 having a memory storing a data set containing drug identification information corresponding to the drug filled in the syringe body 201 is attached to the syringe body 201 in advance. 200 will be provided to medical institutions.

FIG. 5 shows a schematic configuration diagram of the communication device 300. As described above, the communication device 300 is, for example, an RF tag. The communication device 300 includes a communication unit 310 and a memory 320.

The communication unit 310 wirelessly communicates with the reader 170 (see FIG. 6) included in the medical pump 100. The communication unit 310 communicates with the medical pump 100 by wireless communication having a short reach, such as NFC.

The memory 320 stores information such as an identifier (ID) unique to the communication device 300 and a data set corresponding to the drug filled in the syringe 200. The ID stored in the memory 320 is information for identifying the communication device 300, and is different for each communication device 300. The data set stored in the memory 320 may include drug identification information such as a drug code.

When the communication unit 310 receives the ID transmission request from the medical pump 100, the communication unit 310 transmits the ID stored in the memory 320 to the medical pump 100. When the communication unit 310 receives the data set transmission request from the medical pump 100, the communication unit 310 transmits the data set stored in the memory 320 to the medical pump 100.

The device configuration of the medical pump 100 will be described again with reference to FIGS. 2 and 3.

The syringe installation unit 6 has an accommodating unit 8 for accommodating the syringe body 201 and a clamp 5. The accommodating portion 8 is a recess having a substantially semicircular cross section for accommodating the syringe body 201, and is formed along the X direction. A tube fixing portion 9 for detachably sandwiching the tube 203 is formed on the wall portion at the end of the accommodating portion 8.

When the clamp 5 is operated to remove the syringe 200 from the syringe installation portion 6, the clamp 5 is pulled in the Y1 direction (frontward direction) against the force of a spring (not shown) and further turned 90 degrees in the R1 direction. By this operation, the fixation of the syringe body 201 by the clamp 5 is released, and the syringe 200 can be removed from the accommodating portion 8. Further, when the clamp 5 is operated to attach the syringe 200 to the syringe installation portion 6, the clamp 5 is pulled in the Y1 direction against the force of a spring (not shown) and turned 90 degrees in the R2 direction by the force of the spring. Return to the Y2 direction. By this operation, the syringe body 201 can be accommodated in the accommodating portion 8 and fixed by the clamp 5. A part of the right end 8E of the accommodation part 8 of the syringe installation part 6 is a notch so that the clamp 5 can fix the syringe 200 having various capacitys such as 5mL, 10mL, 20mL, 30mL, and 50mL. It has become.

When the syringe body 201 is accommodated and fixed in the accommodating portion 8, the syringe pusher 202 is arranged in the syringe pusher drive portion 7.

The X, Y, and Z directions in FIGS. 2 and 3 are orthogonal to each other, and the Z direction is the vertical direction.

Next, with reference to FIG. 6, an example of electrical configuration of the medical pump 100 shown in FIG. 1 will be described in detail.

In FIG. 6, the medical pump 100 has a control unit (computer) 180 that determines and controls the overall operation. The control unit 180 is, for example, a one-chip microcomputer.

In the control unit 180, the power ON / OFF button 4A and the switch 111 are connected.

The switch 111 supplies power to the control unit 180 from either the power converter unit 112 or the rechargeable battery 113 by switching between the power converter unit (power supply unit) 112 and the rechargeable battery 113 such as a lithium ion battery. To do.

The power converter unit 112 is connected to the commercial AC power supply 115 via the outlet 114.

In FIG. 6, the pump unit 160 is electrically connected to the control unit 180. The pump unit 160 administers the drug to the patient in response to a command from the control unit 180.

In FIG. 6, the main body flange sensor 120 for detecting that the main body flange 209 of the syringe 200 is set at a predetermined position and the pusher flange 205 of the syringe 200 are set at a predetermined position in the pump unit 160. A pusher flange sensor 121 that detects the presence is arranged. The main body flange sensor 120 notifies the control unit 180 whether or not the main body flange 209 is set at a predetermined position. The pusher flange sensor 121 notifies the control unit 180 whether or not the pusher flange 205 is set at a predetermined position.

The clamp sensor 122 of the pump unit 160 notifies the control unit 180 whether or not the syringe body 201 is securely clamped by the clamp 5 by detecting the position state of the clamp 5.

The clutch sensor 123 of the pump unit 160 notifies the control unit 180 whether or not the syringe pusher 202 is securely attached to the slider 10 by the clutch 11.

When the motor 133 of the syringe pusher drive unit 7 of the pump unit 160 is driven by the motor driver 134 according to the command of the control unit 180, the feed screw 135 is rotated to move the slider 10 in the T direction. As a result, the slider 10 presses the pusher flange 205 of the syringe pusher 202 in the T direction, and the drug in the syringe body 201 shown in FIG. 3 is passed through the tube 203 to the patient P via the indwelling needle 204. Syringe accurately.

In FIG. 6, the fast forward switch button 4B, the start switch button 4C, the stop switch button 4D, and the menu selection button 4E are electrically connected to the control unit 180. When the start switch button 4C is pressed, a control signal for starting liquid feeding is input to the control unit 180. Further, when the stop switch button 4D is pressed, a control signal for stopping the liquid feeding is input to the control unit 180.

In FIG. 6, the display unit driver 130 is electrically connected to the control unit 180. The display unit driver 130 drives the display unit 3 in response to a command from the control unit 180 to display various information on the display unit 3.

In FIG. 6, the notification unit 131 is electrically connected to the control unit 180. The notification unit 131 notifies various alarm contents by voice, light, vibration, or the like according to the command of the control unit 180. Further, when the control unit 180 notifies various alarm contents by displaying on the display unit 3, the display unit 3 may have a function as a notification unit.

The communication unit 140 transmits / receives data to / from a server of a medical institution or the like via a network. Further, the communication unit 140 may transmit / receive data by locally connecting to a computer such as a desktop computer.

The reader 170 communicates with the communication unit 310 of the communication device 300 attached to the syringe 200 by wireless communication having a short reach, such as NFC.

The reader 170 transmits an ID transmission request to the communication device 300. The reader 170 reads the ID transmitted from the communication device 300 in response to the transmission request from the reader 170. Further, the reader 170 transmits a data set transmission request to the communication device 300. The reader 170 reads the data set transmitted from the communication device 300 in response to the transmission request from the reader 170.

The storage unit 110 may be configured by using, for example, a semiconductor memory, a magnetic memory, or the like. The storage unit 110 stores various information and programs necessary for the operation of the medical pump 100.

The storage unit 110 may store a drug library containing a plurality of drug profiles. The storage unit 110 can store a drug library customized by the medical institution that owns the medical pump 100. For example, the control unit 180 downloads the drug library stored in the server of the medical institution to the storage unit 110 via the communication unit 140, so that the storage unit 110 stores the drug library customized by the medical institution. can do.

The control unit 180 causes the reader 170 to read the ID of the communication device 300 a plurality of times at a predetermined timing. The details of the predetermined timing will be described later.

The control unit 180 determines whether the IDs read by the reader 170 from the communication device 300 a plurality of times match. When the IDs read a plurality of times match, the control unit 180 causes the reader 170 to start reading the data set stored in the communication device 300. If the IDs read a plurality of times do not match, the control unit 180 does not allow the reader 170 to read the data set stored in the communication device 300.

In this way, the ID of the communication device 300 is read a plurality of times, and only when the IDs read a plurality of times match, the data set is read from the communication device 300, so that the medical pump 100 becomes the medical pump 100. It is possible to suppress the acquisition of the data set from the communication device 300 or the like attached to the syringe 200 that is not attached. This is because, for example, when the user holds the syringe 200 and is near the medical pump 100, the position of the syringe 200 moves with the movement of the user, so that the syringe 200 is accidentally positioned at a position where the reader 170 can read the ID. This is possible, but it rarely stays in that position while the reader 170 reads the ID multiple times.

For example, when the acquired data set includes drug identification information, the control unit 180 can read the drug profile corresponding to the drug identification information from the storage unit 110. The control unit 180 sets administration information and the like based on the drug profile information read from the storage unit 110. As described above, the administration information includes the reference administration rate, the upper limit value / the lower limit value of the administration rate, and the like.

When the control unit 180 reads the drug profile corresponding to the drug filled in the syringe 200 mounted on the medical pump 100, the control unit 180 updates the display content of the display unit 3 by reflecting the information contained in the drug profile. ..

FIG. 7 shows an example of the display of the display unit 3 when the control unit 180 reads the drug profile. In the example shown in FIG. 7, the drug name display field 701, the drug color display field 702, and the administration setting display field 703 are displayed. If there is a message, the message is displayed in the message field 704.

In the drug name display field 701, a drug name such as "nitroglycerin" is displayed. In the drug color display field 702, a preset color corresponding to the drug is displayed.

In the administration setting display column 703, for example, a reference administration rate and a reference flow rate are displayed. In the example shown in FIG. 7, 1.00 [μg / kg / min] is displayed as the reference administration rate, and 1.20 [mL / h] is displayed as the reference flow rate. The user can change, for example, the reference dosing rate as needed. However, if the value set by the user is above or below the upper limit of the administration rate specified in the drug profile, the control unit 180 causes the notification unit 131 to notify the warning. When the display unit 3 functions as a notification unit, the control unit 180 may notify the warning by changing the display of the display unit 3. The medical pump 100 can thereby prevent the user from administering the drug at a dosing rate greater than or less than the lower limit of the dosing rate specified in the drug profile.

When the control unit 180 reads the drug profile, a message such as "drug recognized" is displayed in the message field 704.

When the start switch button 4C is pressed, the control unit 180 controls the pump unit 160 so as to deliver the drug to the patient according to the set administration information.

The following Examples 1 to 4 will be described with respect to a predetermined timing at which the control unit 180 causes the reader 170 to read the ID of the communication device 300.

(Example 1 of reading timing)
The operation of the medical pump 100 according to the first embodiment of the reading timing will be described with reference to the flowchart shown in FIG.

The control unit 180 of the medical pump 100 determines whether or not any one of the clamp 5 and the clutch 11 as a part of the mounting unit has mounted the syringe 200 on the medical pump 100 by the clamp sensor 122. And it is monitored by the clutch sensor 123 (step S101).

When it is determined that neither the clamp 5 nor the clutch 11 has the syringe 200 attached to the medical pump 100 (No in step S101), the control unit 180 repeats the process of step S101.

When either the clamp 5 or the clutch 11 determines that the syringe 200 is attached to the medical pump 100 (Yes in step S101), the control unit 180 causes the reader 170 to read the ID from the communication device 300. .. For example, when the clamp 5 attaches the syringe 200 to the medical pump 100, the control unit 180 causes the reader 170 to read the ID from the communication device 300. The control unit 180 stores the read ID of the communication device 300 in the storage unit 110 (step S102).

The control unit 180 monitors with the clamp sensor 122 and the clutch sensor 123 whether or not both the clamp 5 and the clutch 11 as all the mounting units mount the syringe 200 on the medical pump 100 (step). S103).

When it is determined that both the clamp 5 and the clutch 11 do not attach the syringe 200 to the medical pump 100 (No in step S103), the control unit 180 repeats the process of step S103.

When it is determined that both the clamp 5 and the clutch 11 have attached the syringe 200 to the medical pump 100 (Yes in step S103), the control unit 180 causes the reader 170 to read the ID from the communication device 300 again. The control unit 180 stores the read ID of the communication device 300 in the storage unit 110 (step S104).

The control unit 180 determines whether or not the two read IDs match (step S105).

When the two read IDs match (Yes in step S105), the control unit 180 causes the reader 170 to start reading the data set stored in the communication device 300 (step S106).

If the two IDs read do not match (No in step S105), the control unit 180 does not allow the reader 170 to read the data set stored in the communication device 300 (step S107).

In steps S101 and S103, an example of determining the attachment of the syringe 200 by the clamp sensor 122 and the clutch sensor 123 has been shown. Further, the main body flange sensor 120 and the pusher flange sensor 121 are used to determine the syringe for the medical pump 100. The attachment of 200 may be determined. For example, when the clamp sensor 122 and the main body flange sensor 120 detect that the syringe 200 is attached to the medical pump 100 in step S101, it may be determined as Yes in step S101. Further, in step S103, when all of the clamp sensor 122, the clutch sensor 123, the main body flange sensor 120, and the pusher flange sensor 121 detect the attachment of the syringe 200, it may be determined as Yes in step S103.

In this embodiment, the control unit 180 causes the reader 170 to start reading the ID of the communication device 300 even before the attachment of the syringe 200 by all the attachment units is completed. As a result, the medical pump 100 can read the data set from the communication device 300 with a short waiting time after the installation of the syringe 200 is completed.

(Example 2 of reading timing)
The operation of the medical pump 100 according to the second embodiment of the reading timing will be described with reference to the flowchart shown in FIG.

The control unit 180 of the medical pump 100 monitors whether or not the attachment of the syringe 200 to the medical pump 100 is completed by the clamp sensor 122, the clutch sensor 123, the main body flange sensor 120, and the pusher flange sensor 121. Yes (step S201).

When it is determined that the attachment of the syringe 200 to the medical pump 100 by all the attachment parts such as the clamp 5 is not completed (No in step S201), the control unit 180 repeats the process of step S201.

When it is determined that the attachment of the syringe 200 to the medical pump 100 by all the attachment parts such as the clamp 5 is completed (Yes in step S201), the control unit 180 causes the reader 170 to read the ID from the communication device 300. .. The control unit 180 stores the read ID of the communication device 300 in the storage unit 110 (step S202).

The control unit 180 determines whether or not a predetermined time has elapsed from reading the ID of the communication device 300 in step S202 (step S203).

If it is determined that the predetermined time has not elapsed (No in step S203), the control unit 180 repeats the process of step S203.

When it is determined that the predetermined time has elapsed (Yes in step S203), the control unit 180 causes the reader 170 to read the ID from the communication device 300 again. The control unit 180 stores the read ID of the communication device 300 in the storage unit 110 (step S204).

Since the processing of steps S205 to S207 is the same as the processing of steps S105 to S107 shown in FIG. 8, the description thereof will be omitted.

The longer the predetermined time in step S203, the more likely it is that a user with the non-mounted syringe 200 will be away from the medical pump 100 in the meantime, thus reducing the possibility of reading the data set from the non-mounted syringe 200. However, it takes a long time to read the data set from the syringe 200. Further, if the predetermined time is shortened, the time from reading the data set from the syringe 200 can be reduced, but since it is highly possible that the user holding the syringe 200 that is not attached stays in the vicinity of the medical pump 100, the attachment is made. It is more likely that the dataset will be read from the syringe 200 that is not. Since there is such a trade-off relationship, the predetermined time in step S203 is preferably about 100 ms to 1.5 s in consideration of the balance between the two.

In this embodiment, the control unit 180 causes the reader 170 to start reading the ID of the communication device 300 after the attachment of the syringe 200 to the medical pump 100 is completed. As a result, the medical pump 100 can read the data set from the syringe 200 in a state where it is unlikely that the syringe 200 that is not mounted is nearby, so that the data set may be erroneously read from the syringe 200 that is not mounted. It can be further reduced.

(Example 3 of reading timing)
The operation of the medical pump 100 according to the third embodiment of the reading timing will be described with reference to the flowchart shown in FIG.

The control unit 180 of the medical pump 100 is for removing the syringe 200 from any of the clamp 5 and the clutch 11 as a part of the mounting parts in the state where the syringe 200 is mounted on the medical pump 100. Is monitored by the clamp sensor 122 and the clutch sensor 123 (step S301).

If it is determined that neither the clamp 5 nor the clutch 11 has been operated to remove the syringe 200 (No in step S301), the control unit 180 repeats the process of step S301.

When it is determined that the operation for removing the syringe 200 has been performed for any one of the clamp 5 and the clutch 11 (Yes in step S301), the control unit 180 causes the reader 170 to read the ID from the communication device 300. The control unit 180 stores the read ID of the communication device 300 in the storage unit 110 (step S302).

The control unit 180 determines whether or not the read IDs continuously match a predetermined number of times or more (step S303).

If the read IDs do not match a predetermined number of times or more in succession (No in step S303), the control unit 180 waits for a predetermined time to elapse (step S304), and then returns to the process of step S302. That is, in step S303, the control unit 180 causes the reader 170 to read the ID from the communication device 300 at a predetermined time cycle until it is determined that the read IDs continuously match a predetermined number of times or more.

In step S303, when the read IDs match a predetermined number of times or more in succession (Yes in step S303), the control unit 180 causes the reader 170 to start reading the data set stored in the communication device 300. (Step S305).

The predetermined time in step S304 may be, for example, about 100 ms. The predetermined number of times in step S303 may be, for example, about 10 times.

In this embodiment, the control unit 180 causes the reader 170 to start reading the ID from the communication device 300 as soon as the operation of removing the syringe 200 before replacement from the medical pump 100 is started. As a result, the medical pump 100 can read the data set from the communication device 300 attached to the syringe 200 to be replaced as soon as the syringe 200 to be replaced enters the communicable range of the reader 170.

(Example 4 of reading timing)
When the control unit 180 of the medical pump 100 starts the reader 170 to read the ID from the communication device 300 at any of the timings 1 to 3 of the above-mentioned reading timing, it continues as it is for a predetermined time. The ID may be read from the communication device 300 at a cycle. The control unit 180 compares the IDs read from the communication device 300 in a predetermined time cycle, and when the read IDs match a predetermined number of times or more, the reader 170 starts reading the data set stored in the communication device 300. You may let me.

Further, the control unit 180 may cause the reader 170 to read the ID from the communication device 300 again when the liquid feeding of the medical pump 100 is started, that is, when the start switch button 4C is pressed. If the ID read at the start of liquid feeding of the medical pump 100 does not match the ID read before that, the control unit 180 may shift the medical pump 100 to the liquid feeding impossible mode. Here, the "liquid feeding impossible mode" is a mode in which the liquid feeding is not started even if the start switch button 4C is pressed by the user. When shifting to the liquid feeding impossible mode, the control unit 180 may notify the notification unit 131 of the shift to the liquid feeding impossible mode by voice or the like.

In this embodiment, the control unit 180 causes the reader 170 to read the ID from the communication device 300 again at the start of liquid feeding of the medical pump 100. As a result, the medical pump 100 can more reliably read the data set from the communication device 300 attached to the syringe 200 attached to the medical pump 100.

(End of reading)
The control unit 180 of the medical pump 100 determines that the IDs read a plurality of times match, and when the data set is read from the communication device 300, the process of reading the ID and the data set from the communication device 300 is completed. After that, the reading process is not executed until the syringe 200 is replaced. As a result, the medical pump 100 can prevent the medical pump 100 from reading and overwriting unintended data after reading the correct data set.

Further, when the start switch button 4C is pressed while the data set has not been read from the syringe 200 mounted on the medical pump 100, the control unit 180 receives the ID and data set from the subsequent communication device 300. The reading process may be terminated. The state in which the data set cannot be read from the syringe 200 mounted on the medical pump 100 may occur, for example, when the communication device 300 is not attached to the syringe 200. In this case, since the data set has not been read from the syringe 200, the medical pump 100 is in a state where the drug profile corresponding to the drug filled in the attached syringe 200 cannot be read. When the user presses the start switch button 4C in such a state, it is considered that the user intentionally wears the syringe 200 to which the communication device 300 is not attached, and the control unit 180 determines that the subsequent communication device is attached. The process of reading the ID and data set from 300 is completed.

Further, the control unit 180 ends the subsequent reading process of the ID and the data set from the communication device 300 when the user manually selects the drug profile or manually changes the drug administration unit. You may. As a result, it is possible to prevent the control unit 180 from reading the data set from the syringe 200 and intentionally overwriting the manually set setting by the user.

As described above, in the medical pump 100 according to the present embodiment, the control unit 180 determines whether the IDs read a plurality of times from the communication device 300 match, and if the IDs read a plurality of times match, the communication is performed. Start reading the data set from the device 300. Thereby, the medical pump 100 according to the present embodiment can suppress the acquisition of various data from the communication device 300 attached to the syringe 200 which is not attached to the medical pump 100.

Further, in the present embodiment, when a part of the mounting parts of the plurality of mounting parts mounts the syringe 200 on the medical pump 100, the control unit 180 causes the communication device 300 to read the ID and mounts the plurality of mounting units. When all of the parts attach the syringe 200 to the medical pump 100, the ID may be read again from the communication device 300. In this way, the control unit 180 causes the reader 170 to start reading the ID from the communication device 300 even before the mounting of the syringe 200 is completed, so that the medical pump 100 can perform after the mounting of the syringe 200 is completed. The data set can be read from the communication device 300 with a short waiting time.

Further, in the present embodiment, when the attachment of the syringe 200 to the medical pump 100 is completed, the control unit 180 causes the communication device 300 to read the ID, and after the attachment of the syringe 200 to the medical pump 100 is completed. After a lapse of a predetermined time, the ID may be read again from the communication device 300. As a result, the medical pump 100 can read the data set from the syringe 200 in a state where the non-mounted syringe 200 is unlikely to be in the vicinity of the medical pump 100, so that the data set is erroneously read from the non-mounted syringe 200. The readability can be further reduced.

Further, in the present embodiment, when any one of the plurality of mounting units is operated, the control unit 180 causes the communication device 300 to read the ID in a predetermined time cycle, and when the read IDs match a predetermined number of times or more, Reading of the data set from the communication device 300 may be started. As a result, the medical pump 100 can read the data set from the communication device 300 attached to the syringe 200 to be replaced as soon as the syringe 200 to be replaced enters the communicable range of the reader 170.

Further, in the present embodiment, the control unit 180 causes the communication device 300 to read the ID again at the start of the liquid feeding of the medical pump 100, and the ID read at the start of the liquid feeding does not match the previously read ID. , The medical pump 100 may be shifted to the non-delivery mode. As a result, the medical pump 100 can more reliably read the data set from the communication device 300 attached to the syringe 200 attached to the medical pump 100.
