Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drug solution injection system for injecting a drug solution of a drug solution syringe into a subject using a drug solution injection device, and in particular, to a CT (Computed Tomography) scanner, an MRI (Magnetic Resonance Imaging) device, a PET (Position Emission Tomography, ultrasonography), and the like. The present invention relates to a drug solution injection system for injecting a contrast agent into a subject whose fluoroscopic image is captured by a fluoroscopic imaging device such as a device.
[0002]
[Prior art]
At present, there are a CT scanner, an MRI apparatus, a PET apparatus, an ultrasonic diagnostic apparatus, a CT angio apparatus, an MRA (MR Angio) apparatus, and the like as a fluoroscopic imaging apparatus for imaging a fluoroscopic image of a subject. When the above-described fluoroscopic imaging apparatus is used, a liquid medicine such as a contrast medium or a physiological saline may be injected into a subject, and a liquid medicine injection apparatus that automatically executes the injection has been put to practical use.
[0003]
Such a liquid injector has, for example, an injection executing mechanism including a drive motor and a slider mechanism, and a liquid syringe is detachably mounted. The liquid syringe has a structure in which a piston member is slidably inserted into a cylinder member, and there are a prefilled type and a non-prefilled type.
[0004]
The pre-filled type liquid syringe is filled with a liquid chemical in a cylinder member and is shipped in a state where the whole is sealed with a packing material. In the non-prefilled type liquid syringe, a desired liquid is filled in a cylinder member by a user. In addition, since only the prefilled type liquid syringe is applied to the present invention, the following description is based on the premise that the liquid syringe is a prefilled type.
[0005]
When injecting the liquid medicine of the liquid syringe as described above into the subject, the operator prepares a liquid syringe of an appropriate liquid medicine and takes out the liquid syringe from the packing material. When the medicinal solution syringe is connected to the subject by an extension tube and loaded into the infusion executing mechanism, the medicinal solution injector moves the piston member and the cylinder member relative to each other by the injecting mechanism in response to a predetermined operation. Will be injected with the drug solution.
[0006]
In this case, the operator determines the injection speed and total injection amount in consideration of the type of the chemical solution, etc., and inputs the data to the chemical solution injection device, and the chemical solution injection device injects the chemical solution to the subject in accordance with the input data. I do. For example, if a contrast agent is injected as a drug solution, the contrast of the subject changes, so that a good fluoroscopic image is captured by the fluoroscopic imaging device.
[0007]
In addition, there is a drug solution injection device that is capable of injecting physiological saline together with the contrast agent into the subject.In such a case, the operator instructs the operator to inject the saline in conjunction with the completion of the injection of the contrast agent, if desired. Data is input to the liquid injector along with the total amount of injection.
[0008]
Then, the liquid injector injects a contrast medium into the subject according to the input data, and then automatically injects physiological saline. For this reason, it is possible to reduce the consumption of the contrast agent by boosting the contrast agent with the physiological saline, and to reduce the artifact by the physiological saline.
[0009]
The above-described liquid injector has been invented and filed by the present applicant in the past (for example, see Patent Documents 1 and 2).

[0011]
[Problems to be solved by the invention]
In the above-described liquid injector, the liquid can be injected into the subject from the liquid syringe, but the operator needs to select an appropriate liquid syringe in order to inject a proper liquid. However, since there is a product syringe having the same appearance even if the kind of the drug solution is different, there is a possibility that an operator may load a drug solution syringe of an inappropriate drug solution into the drug solution injector.
[0012]
In addition, as described above, it is necessary to input data such as the injection speed and the total injection amount into the chemical liquid injector according to the chemical liquid to be used, but this operation is complicated and difficult for an unskilled operator, Inappropriate numerical values cannot be prevented from being input. In particular, there are products in which the concentration of the active ingredient differs up to several times in current contrast agents, and if this is not taken into account, several times or a fraction of the appropriate amount of contrast agent will be injected.
[0013]
The present invention has been made in view of the above-described problems, and has as its object to provide a drug solution injection system that can prevent an inappropriate drug solution syringe from being loaded into a drug solution injection device.

[0050]
More specifically, in the liquid injector 100 of the present embodiment, as described above, the contrast medium is injected into the subject, and then the physiological saline is injected. Therefore, the above-described operating conditions include the contrast injection mechanism 123 and the saline injection mechanism. Data is set so as to link the injection operation with the reference numeral 124.
[0051]
Further, the operating conditions of the contrast injection mechanism 123 are set as data in a variable pattern that changes the injection speed of the contrast agent over time so as to maintain a state in which the contrast of the fluoroscopic image by the contrast agent is close to the optimum value. I have. This variable pattern is optimally set based on experimental results. For example, as shown in FIG. 10, the injection speed is linearly reduced from the start of injection until a predetermined time, and thereafter, the injection speed is kept constant. It is set as such.
[0052]
In the liquid injector 100 of the present embodiment, since various variable patterns are registered in data for each imaging site, when one of a plurality of imaging sites is selected by the manual operation of the touch panel 105 as described above, the imaging site is selected.

For example, when the total amount of iodine injection is set to “A (g)” in the variable pattern registered as data for each imaging site, the iodine concentration of the drug solution data of the contrast agent whose data is searched is “B (g)”. / Ml) ", the total injection amount of the contrast agent is calculated as" A / B (ml) "in inverse proportion to the concentration.
[0056]
When the total injection amount is calculated in this way, as shown in FIG. 10, when a variable pattern is registered as data with a predetermined waveform, for example, the area surrounded by the waveform and the x / y axes is the total injection amount. , The waveform of the variable pattern is moved up and down without changing the injection time.
[0057]
The injection control unit 154 corresponds to a function of the CPU 131 driving the drive motor 121 of the contrast / saline injection mechanism 123 or 124 in accordance with the processing data, and the contrast / satellite injection is performed under the operating conditions adjusted by the operation adjusting unit 153. The operation of the mechanisms 123 and 124 is controlled.
[0058]
The confirmation storage unit 156 stores various types of confirmation conditions corresponding to the identification data and the chemical liquid data, and the warning output unit 157 stores the optically read identification data and the retrieved chemical liquid data in the confirmation storage unit 156. If the data does not match the confirmation condition, a confirmation warning is displayed and output on the touch panel 105 with a predetermined guidance text or the like.
[0059]
More specifically, in the drug solution injection system 1000 of the present embodiment, the identification data optically read by the barcode scanner 108 is stored in the drug solution injection device 100 because the identification data of the available contrast agent and physiological saline is registered in the drug solution injection device 100. If the data is not registered, a confirmation warning such as “The information of this barcode is not registered. Please confirm whether the medicine is usable.” Is displayed and output on the touch panel 105.
[0060]
Further, since the types of available contrast agents differ depending on the imaging site, the correspondence between the liquid medicine data and the imaging site is also registered as a confirmation condition. Therefore, if the correspondence relationship between the searched drug solution data and the input operation of the imaging site is not registered, "The combination of this site and the contrast agent is not registered. Confirmation warning such as "Please." Is displayed and output on the touch panel 105.
[0061]

Check the site and the contrast agent. "Is displayed on the touch panel 105 (step T5).
[0073]
In these cases, the operator checks the liquid medicine syringe 200 and, if it is determined that the liquid medicine is not appropriate, performs an input operation of resetting data on the touch panel 105 (step T6). Then, the liquid injector 100 returns to the initial state, and enters a state of waiting for optical reading of the barcode (step T1).
[0074]
On the other hand, when the operator who has checked the liquid syringe 200 determines that there is no problem, for example, when a predetermined operation is performed on the liquid injector 100, a list of the liquids registered as data is displayed and output on the touch panel 105 (not shown). ). Then, when the operator selects and operates a desired chemical liquid on the touch panel 105 as confirmation completion (step T5), the chemical liquid injector 100 sets chemical liquid data corresponding to the input operation and displays and outputs the data on the touch panel 105 (step T8). ).
[0075]
Then, the operator checks the displayed chemical liquid data. If it is determined that the chemical liquid is not appropriate, the operator performs a data reset operation on the touch panel 105 (step T9). The injection device 100 deletes the set chemical liquid data and returns to the initial state (steps T10 and T1).
[0076]
On the other hand, when the operator sets data of the imaging site in the drug solution injector 100, as shown in FIG. 8, a schematic image of a plurality of body divisions is displayed and output on the touch panel 105 corresponding to the human body shape. As shown in FIG. 14, the operator selects and operates one of the schematic images of the plurality of body sections as desired (step E1).
[0077]
Then, data of a schematic image of a plurality of imaging sites related to the selected body section is retrieved (step E2), and displayed and output below the schematic image of the body section (step E3). At this time, only the schematic image of the selected body segment is turned bright while the other schematic images are darkened, and the schematic image of the scanner mechanism is displayed and output above the schematic image of the selected body segment.
[0078]
Next, when the operator selects one of the plurality of imaging sites (step E4), the selected imaging site is set in data in a predetermined area of the RAM 133 (step E5), and as shown in FIG. Only one selected schematic image turns bright while the other schematic images turn dark.
[0079]
In the liquid injector 100 of the present embodiment, when an imaging part is selected as described above, it is determined whether or not the imaging part matches the confirmation condition (step E6). If this matching is also determined, the imaging part is determined. Is retrieved from the RAM 133 (step E10).
[0080]
On the other hand, if the imaging region does not match the check condition (step E6), for example, if the correspondence between the set chemical liquid data and the selected imaging region is not registered, the “combination of this region and contrast agent” Is not registered. Check the region and the contrast agent. "Is displayed on the touch panel 105 (step E7).
[0081]
In this case, the operator confirms the imaging site and the liquid syringe 200, and if the relationship is determined to be inappropriate, performs an input operation of data reset on the touch panel 105 (step E9). Then, the liquid injector 100 returns to the initial state, and is in a state of waiting for the selection operation of the body division (step E1).
[0082]
On the other hand, if the operator who has checked the imaging site and the medical fluid syringe 200 determines that there is no problem, the operator inputs a confirmation completion on the touch panel 105 (step E8), and the liquid injector 100 responds to the imaging site. Then, data of the operating condition is retrieved from the RAM 133 (step E10).
[0083]
In the liquid injector 100 of the present embodiment, when the operating conditions are searched for data as described above, the operating conditions are adjusted according to the liquid data (step E11). The adjusted operating conditions are set as data. For example, as shown in FIG. 9, the injection speed, the total injection amount, and the injection time of the adjusted operating conditions are displayed and output on the touch panel 105 (step E10).
[0084]
Then, the operator confirms the displayed operating condition, and if satisfied, presses the “OK” icon at the upper right of the screen with his / her finger as shown in FIG. 12 (step S5). Then, the liquid injector 100 controls the operation of the contrast / saline injection mechanisms 123 and 124 under the adjusted operating conditions (step S7), and thus the contrast agent and the physiological saline are injected into the subject.
[0085]
In this case, as shown in FIG. 10, the contrast agent is injected into the subject in a variable pattern in which the injection speed is linearly reduced from the start of the injection until a predetermined time and the injection speed is kept constant thereafter, and the injection is completed. Then, a physiological saline having a volume proportional to the contrast agent is injected into the subject.
[0086]
[Effects of Embodiment]
In the drug solution injection system 1000 of the present embodiment, the identification data of the drug solution is recorded in a bar code on the packaging material 204 of the drug syringe 200, and the drug solution injection device 100 that stores the drug solution data for each of the identification data uses the bar code. The reader 108 reads the identification data from the drug solution syringe 200, searches the drug solution data, and displays and outputs the data on the touch panel 105. Therefore, the operator can easily and surely confirm various data of the chemical solution to be injected into the subject, and prevent a medical error in which an inappropriate chemical solution is injected into the subject.
[0087]
In addition, if the liquid medicine data is not searched for based on the read identification data, the liquid medicine injecting apparatus 100 notifies and outputs the data with a confirmation warning, thereby preventing the liquid medicine whose data is not registered from being used without being confirmed. it can. Further, even when the chemical liquid data does not match the various confirmation conditions stored in the data, this is notified and output with a confirmation warning, so that it is possible to prevent the chemical liquid that does not match the confirmation conditions from being used without being confirmed.
[0088]
Further, in the present embodiment, since the bar code portion 205 is formed on the packing material 204 of the liquid syringe 200, the liquid medicine data can be confirmed without taking out the liquid syringe 200 from the packing material 204. It can be prevented that the user does not use the printer while taking it out of the printer 204.
[0089]
Moreover, the liquid injector 100 of the present embodiment controls the operation of the contrast / saline injection mechanisms 123 and 124 in accordance with the retrieved liquid data, so that the liquid injector 100 can respond to the liquid without requiring complicated input operations. The injection operation can be performed simply and reliably.
[0090]
In particular, the liquid injector 100 of the present embodiment sets operating conditions in accordance with the operation of selecting the imaging region of the subject, and adjusts the operating conditions in accordance with the liquid chemical data, thus requiring a complicated input operation. The injection operation corresponding to the medical solution and the imaging site can be easily and reliably performed without performing the above operation.
[0091]
In addition, a schematic image of a plurality of body divisions is displayed and output on the touch panel 105 in the form of a human body, and when one of them is selected and operated, a schematic image of a plurality of corresponding imaging parts is displayed and output, and when one of the selected images is selected and operated. Since the corresponding operating condition is searched for and set, the operating condition for each imaging part can be set by an extremely simple operation.
[0092]
In addition, the appropriateness of the correspondence between the searched liquid drug data and the selected imaging part is automatically checked. If this is not appropriate, a notification is output with a confirmation warning. Injection of the agent can also be prevented.
[0093]
In addition, in the liquid injector 100 of the present embodiment, the contrast medium and the physiological saline are injected into the subject by the contrast / saline injection mechanisms 123 and 124, but the interlocking is automatically performed according to the operating conditions, which is complicated. The contrast medium and the physiological saline can be appropriately interlocked and injected into the subject without requiring a complicated operation.
[0094]
Furthermore, in the liquid injector 100 of the present embodiment, since the injection speed of the contrast agent is changed with time according to the variable pattern, it is possible to maintain a state where the CT value is close to the optimum value, and the CT scanner 300 An optimal perspective image can be captured. Moreover, since the amount of the contrast agent used can be minimized, the amount of the contrast agent can be saved, and the health of the subject can be contributed.
[0095]
As shown in FIG. 10, an experiment was performed in which the injection rate was linearly reduced from the start of the injection to a predetermined time and thereafter the contrast medium was injected in a variable pattern that maintained the injection rate constant. As shown, it was confirmed that the state where the CT value was close to the optimum value was maintained for a long time.
[0096]
The variable pattern as described above is different for each imaging region, and the setting and operation thereof are complicated. However, the liquid injector 100 of the present embodiment is configured such that the operator can use a schematic image to identify the body section and the imaging region. When selected, an appropriate variable pattern is set, so that a complicated operation can be executed by an extremely simple operation.
[0097]
[Modification of Embodiment]
The present invention is not limited to the above-described embodiment, and allows various modifications without departing from the gist thereof. For example, in the above embodiment, the liquid injector 100 having the contrast / saline injection mechanisms 123 and 124 as the injection head 110 injects the contrast agent and the physiological saline, but one injection head 110 only uses the contrast agent. Can be also implemented.
[0098]
In the above-described embodiment, the barcode portion 205 is formed on the packing material 205 of the liquid syringe 200. However, the barcode portion 205 may be formed on the cylinder member 201 or the piston member 202. is there. Furthermore, although the identification data of the chemical solution is recorded in the barcode unit 205 as an example, it can be recorded in a magnetic stripe, an IC (Integrated Circuit) chip, the outer shape of the cylinder member 201, and the like. .
[0099]
Further, in the above embodiment, the identification data of the medical solution is recorded in the chemical syringe 200, and various types of chemical data are registered in the chemical injection device 100 for each identification data. It is also possible to record the data directly.
[0100]
Further, in the above-described embodiment, the chemical liquid injection system 100 is exemplified by the chemical liquid syringe 200 that can be exchanged with the chemical liquid injection device 100. It is also possible (not shown).
[0101]
This liquid medicine heat retaining device includes a case for storing a plurality of liquid medicine syringes 200, and has a heat retaining execution mechanism for keeping the stored liquid medicine syringe 200 at a predetermined temperature appropriate for the liquid medicine. Therefore, such a chemical liquid warming device may include the data storage unit 141, the barcode reader 108, the data search unit 142, and the data display unit 143.
[0102]
In this case, since the liquid medicine data can be confirmed when the liquid medicine syringe 200 is kept warm by the liquid medicine preserving device, the liquid medicine data can be confirmed before the liquid medicine syringe 200 is loaded into the liquid medicine injection device 100. Further, the above-described chemical solution heat retaining device controls the operation of the heat retention performing mechanism in accordance with the identification data and the chemical solution data, so that the chemical solution syringe 200 can be appropriately kept warm.
[0103]
In addition, it is possible that the chemical solution heat retaining device has the data storage means 141, the barcode reader 108, and the data search means 142, and the chemical solution injection device 100 has the data display means 143. In addition to having the reader 108, the liquid injector 100 may include a data storage unit 141, a data search unit 142, and a data display unit 143.
[0104]
In these cases, when the chemical liquid warming device optically reads the barcode portion 205 of the chemical liquid syringe 200, the chemical liquid data is displayed on the chemical liquid injector 100. You can check before loading.
[0105]
Further, in the above embodiment, the bar code reader 108 is integrally incorporated into the injection device main body 103 of the drug solution injection device 100. However, the handy bar code reader is wired or wirelessly connected to the drug solution injection device 100 or the drug solution warming device. (Not shown).
[0106]
Further, as shown in FIG. 15, a bar code reader 108 and a touch panel 105 can be provided side by side on the injection head 110 of the chemical liquid injector 100. In this case, since the optical reading of the barcode unit 205 and the display output of the chemical liquid data are executed near the position where the liquid syringe 200 is loaded, these can be performed intuitively.
[0107]
In the above embodiment, the injection of the contrast agent and the physiological saline are linked in accordance with the operating conditions. However, the operating conditions can be set to various data as desired. For example, as applied by the present applicant as Japanese Patent Application No. 2002-363675, it is also possible to inject a contrast medium while diluting it with physiological saline depending on operating conditions.
[0108]
In that case, the appropriate iodine concentration differs depending on the contrast agent and the imaging site, and thus, conventionally, the contrast agent was replaced every time the imaging site was changed. However, in the liquid injector 100 of this embodiment, if the bar code unit 205 of the liquid syringe 200 for contrast medium is optically read and an imaging part is selected and operated, an operation of appropriately diluting the contrast agent corresponding to the imaging part is performed. The conditions are set as data.
[0109]
For this reason, if the high-contrast contrast agent is loaded together with the physiological saline into the drug solution injector 100, it is possible to appropriately image and image various imaging sites without replacing the contrast agent, and furthermore, Work load can be reduced. Moreover, since the concentration of iodine can be freely varied by diluting the contrast agent with physiological saline, the contrast agent can be injected into the subject at a concentration of iodine that does not exist in a commercial product. The manual operation of such dilution is cumbersome, but the liquid injector 100 of the present embodiment can appropriately dilute the contrast medium by an extremely simple operation as described above.
[0110]
In the above-described embodiment, the liquid injector 100 adjusts the operating conditions of each imaging site in accordance with the liquid data. However, for example, the body data of the subject such as weight, body type, age, and gender are also injected. It is also possible to make the device 100 input and adjust the operating conditions according to the physical data.
[0111]
Further, in the above-described embodiment, the operation condition is registered for each imaging region and adjusted in accordance with the chemical liquid data. However, for example, the operating condition is registered for each imaging region and each chemical liquid data. It is not impossible to register the operating conditions for each chemical liquid data and to adjust the operating conditions according to the imaging site.
[0112]
Further, in the above-described embodiment, the new chemical liquid data is downloaded from the PC card 106, which is the information storage medium, to the chemical liquid injector 100. However, the operating conditions can be downloaded in the same manner. It is also possible to use various products. Further, it is also possible for the drug solution injector 100 to search for data in real time from the loaded PC card 106 without copying the drug solution data and the like from the PC card 106 to the RAM 133.
[0113]
Alternatively, it is possible to connect the chemical injection device 100 to a device maker or a host computer of the chemical maker online through a communication network such as the Internet, and the chemical injection device 100 can download the chemical liquid data and operating conditions online.
[0114]
Further, in the above-described embodiment, it is assumed that the liquid injection of the liquid injection device 100 and the image capturing of the CT scanner 300 are individually manually operated and executed. However, as the present applicant has filed an application as Japanese Patent Application No. 2003-069870. In addition, the chemical injector 100 and the CT scanner 300 can communicate with each other to link various operations.
[0115]
Further, in the above embodiment, the CT scanner 300 is used as the fluoroscopic imaging device, and the liquid injector 100 injects a contrast agent for CT. However, for example, an MRI device or a PET device is used as the fluoroscopic imaging device, It is also possible for the liquid injector to inject the contrast agent therefor.
[0116]
In the above embodiment, the operation of the CPU 131 in accordance with the computer program stored in the RAM 133 or the like has been described as an example in which various means are logically realized as various functions of the liquid injector 100. However, it is also possible to form each of these various means as unique hardware, and it is also possible to store a part of the means as software in the RAM 133 or the like and form a part as hardware.
[0117]
