[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a chemical injection system that injects a chemical solution of a chemical syringe into a subject with a chemical injection device, and in particular, a CT (Computed Tomography) scanner, an MRI (Magnetic Resonance Imaging) device, a PET (Positron Emission Tomography) device, and an ultrasonic diagnosis. The present invention relates to a chemical liquid injection system that injects a contrast medium into a subject whose fluoroscopic image is captured by a fluoroscopic imaging apparatus such as an apparatus.
[0002]
[Prior art]
Currently, there are CT scanners, MRI apparatuses, PET apparatuses, ultrasonic diagnostic apparatuses, CT angio apparatuses, MRA (MR Angio) apparatuses, and the like as fluoroscopic imaging apparatuses that capture a fluoroscopic image of a subject. When using the fluoroscopic imaging apparatus as described above, a chemical solution such as a contrast medium or physiological saline may be injected into a subject, and a chemical solution injection apparatus that automatically executes this injection has also been put into practical use.
[0003]
Such a chemical injection device has an injection execution mechanism including, for example, a drive motor and a slider mechanism, and a chemical syringe is detachably attached thereto. The chemical 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 prefilled type medical solution syringe is shipped in a state where the cylinder member is filled with the chemical solution and the whole is sealed with a packing material, and the non-prefilled type medical solution syringe is filled with a desired chemical solution by the user in the cylinder member. In addition, since only a prefilled type liquid medicine syringe is applied to this invention, it demonstrates below on the assumption that a liquid medicine syringe is a prefilled type.
[0005]
When injecting the chemical solution of the chemical solution syringe as described above into the subject, the operator prepares a chemical solution syringe of an appropriate chemical solution and takes out the chemical solution syringe from the packing material. When the drug solution syringe is connected to the subject through an extension tube and loaded into the injection execution mechanism, the drug solution injection device moves the piston member and the cylinder member relative to each other by the injection execution mechanism in response to a predetermined operation. The drug solution will be injected into.
[0006]
In that case, when the operator determines the injection speed, total injection amount, etc. in consideration of the type of chemical solution and inputs the data to the chemical injection device, this chemical injection device injects the chemical into the subject according to the input data. To do. For example, if a contrast medium is injected as a chemical solution, the contrast level of the subject changes, and a good fluoroscopic image is captured by the fluoroscopic imaging device.
[0007]
In addition, there is a product that can inject physiological saline together with a contrast agent into a subject, and in that case, the operator may inject the physiological saline in conjunction with the completion of the injection of the contrast agent if desired. Data is input to the chemical injection device along with the total injection volume.
[0008]
Then, this chemical injection device automatically injects physiological saline after injecting a contrast medium into the subject corresponding to the input data. For this reason, the contrast agent can be boosted with physiological saline to reduce the consumption of the contrast agent, and the artifact can be reduced with the physiological saline.
[0009]
In addition, the above-mentioned chemical | medical solution injection | pouring apparatus as mentioned above was invented and applied in the past by this applicant etc. (for example, refer patent document 1, 2).

[0011]
[Problems to be solved by the invention]
In the above-described chemical solution injection device, a chemical solution can be injected into a subject from a chemical solution syringe, but in order to inject an appropriate chemical solution, an operator needs to select an appropriate chemical solution syringe. However, since there is a product with the same appearance even if the type of the chemical solution is different, there is a possibility that an operator may load a chemical solution syringe with an inappropriate chemical solution into the chemical solution injector.
[0012]
In addition, as described above, it is necessary to input data such as the injection speed and the total injection amount corresponding to the chemical solution to be used in the chemical injection device, but this operation is complicated and difficult for unskilled operators, It is not possible to prevent an inappropriate value from being input. In particular, there are products in which the concentration of the active ingredient differs by several times in the current contrast agent. Therefore, several times or a fraction of the appropriate amount of the contrast agent is injected without considering this.

[0044]
More specifically, in the liquid injector 100 of this embodiment, “head, chest, abdomen, and leg” are defined as a plurality of body sections, and schematic images corresponding to each of these are registered in the ROM 132 as data. Has been. Therefore, when a predetermined operation is performed on the drug solution injection device 100 of this embodiment, a schematic image of “head, chest, abdomen, legs” is displayed on the upper part of the screen of the touch panel 105 corresponding to the human body shape as shown in FIG. Display output.
[0045]
Also, in the schematic image of the “head” which is the above-mentioned body classification, schematic images such as “brain part, jaw part, neck part” and the like are registered as a plurality of imaging parts, and similarly, “ The “chest” image is “heart, lung”, the “abdomen” image is “stomach, liver,…”, the “leg” image is “upper, lower”, etc. Schematic images are related and registered.
[0046]
Therefore, when one of the schematic images of a plurality of body ranges displayed and output on the touch panel 105 in the form of a human body is manually operated, a schematic image of the scanner mechanism is displayed and output only on the one schematic image, and is manually operated. Only one schematic image turns bright and the other schematic images turn dark.
[0047]
At the same time, since a schematic image of a plurality of related imaging parts is displayed and output at the lower part thereof, when one of the schematic images of the plurality of imaging parts output and displayed is manually operated, as shown in FIG. Only one of the schematic images turns bright and the other schematic image turns dark.
[0048]

The operation storage condition 151 is retrieved from the operation storage means 151.
[0050]
More specifically, in the drug solution injection device 100 of this embodiment, since the physiological saline is injected after injecting the contrast medium into the subject as described above, the above operating conditions are the contrast injection mechanism 123 and the saline injection mechanism. Data is set so that the injection operation with 124 is linked.
[0051]
In addition, the operating conditions of the contrast injection mechanism 123 are set as data as a variable pattern that changes the injection speed of the contrast medium over time so that the contrast level of the fluoroscopic image by the contrast medium remains close to the optimum value. Yes. This variable pattern is optimally set based on experimental results.For example, as shown in FIG. 10, the injection rate is linearly reduced from the start of injection to a predetermined time, and thereafter the injection rate is kept constant. And so on.
[0052]
In the chemical injection device 100 of this embodiment, since various variable patterns are registered for each imaging region, when one is selected from a plurality of imaging regions by manual operation of the touch panel 105 as described above, the imaging region The operation condition corresponding to is searched for data.
[0053]
The operation adjustment unit 153 corresponds to a function of the CPU 131 executing a predetermined processing operation, and the like. The operation condition of the contrast medium that is searched for data by the operation search unit 152 Adjust according to the concentration.
[0054]
More specifically, in the liquid injector 100 of this embodiment, as described above, a variable pattern that changes the injection rate with time is registered as the operating condition of the contrast agent injection. The data is set so as to satisfy the total injection amount.
[0055]
For example, when the total injection amount of iodine is set to “A (g)” in the variable pattern registered for each imaging region, the iodine concentration of the chemical solution data of the contrast medium searched for data is “B (g / ml) ”, the total injection amount of the contrast agent is calculated as“ A / B (ml) ”in inverse proportion to the concentration of the contrast agent.
[0056]
When the total injection amount is calculated in this way, as shown in FIG. 10, when a variable pattern is registered with a predetermined waveform, for example, the area surrounded by the waveform and the x / y axis 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 means 154 corresponds to the function of the CPU 131 driving the drive motor 121 of the contrast / saline feeding mechanism 123, 124 corresponding to the processing data, and the contrast / saline injection under the operating conditions adjusted by the motion adjusting means 153. The operation of the mechanisms 123 and 124 is controlled.
[0058]
The confirmation storage means 156 stores various confirmation conditions corresponding to the identification data and the chemical liquid data, and the warning output means 157 confirms the optically read identification data and the chemical liquid data retrieved by the confirmation storage means 156. If the data does not match the confirmation condition, a confirmation warning is displayed on the touch panel 105 with a predetermined guidance text.
[0059]
More specifically, in the chemical injection system 1000 according to the present embodiment, the identification information optically read by the barcode scanner 108 is registered in the chemical injection device 100 because the available contrast medium and physiological saline identification data are registered. If the data is not registered, a confirmation warning such as “This barcode information is not registered. Please check if it can be used.” Is displayed on the touch panel 105.
[0060]
In addition, since the types of contrast media that can be used vary depending on the imaging region, the correspondence between the drug solution data and the imaging region is also registered as a confirmation condition. Therefore, if the correspondence between the retrieved drug solution data and the input imaged region is not registered, “The combination of this region and contrast agent is not registered. Check the region and contrast agent. Confirmation warning such as “Please” is displayed on the touch panel 105.
[0061]
The various means of the chemical injection device 100 as described above are realized by using hardware such as the operation panel 104 as necessary, but the main body corresponds to resources and computer programs stored in an information storage medium such as the ROM 132. This is realized by the function of the CPU 131 which is hardware.
[0062]
Such resources include, for example, a data file that associates a schematic image of a plurality of body segments of a human body with a schematic image of a large number of imaging regions, and a contrast / saline injection mechanism 123, 124 for each of a large number of imaging regions of a human body. It consists of a data file of operating conditions, a data file of chemical liquid data for each of a plurality of types of contrast medium and physiological saline identification data, data files of various confirmation conditions, and the like.

[Operation of the embodiment]
In the configuration as described above, when using the chemical injection device 100 of this embodiment, an operator (not shown) places the chemical injection device 100 in the vicinity of the imaging unit 301 of the CT scanner 300 as shown in FIG. Then, as shown in FIG. 3, for example, a chemical syringe 200 of a contrast medium and physiological saline is connected to a subject (not shown) located in the imaging unit 301 with a bifurcated extension tube 210.
[0065]
And the cylinder member 201 of the chemical | medical solution syringe 200 is hold | maintained at the recessed part 112 of the injection | pouring head 110, and the piston member 202 is made to hold | grip to the syringe drive mechanism 120. FIG. In a state where such preparation is completed, as shown in FIG. 12, when an operator executes setting of chemical liquid data or data selection of an imaging part as desired in the chemical injection apparatus 100 (steps S1 to S4), the chemical injection is performed. The apparatus 100 can inject a chemical solution from the chemical solution syringe 200 to the subject (steps S5 to S7).
[0066]
In the chemical solution injection device 100 of this embodiment, since the chemical solution data set by the operator and the selected imaging part are stored, the same chemical solution is used repeatedly or the same part is stored. In the case of repeated imaging, the chemical solution injection can be executed without repeating the setting and selection.
[0067]
On the other hand, when setting the chemical liquid data, as shown in FIG. 6 and FIG. 4, the operator places the bar code portion 205 of the packing material 204 sealing the chemical liquid syringe 200 into the chemical liquid injection as shown in FIG. 13. The barcode reader 108 of the apparatus 100 is optically read.
[0068]
Then, in the chemical injection device 100 according to the present embodiment, the chemical liquid data is searched with the chemical liquid identification data optically read from the barcode unit 205 (steps T1 to T3). It is determined whether they match (step T4).
[0069]
When the retrieved chemical liquid data also matches the confirmation condition, the chemical liquid data is set in a predetermined area of the RAM 133 and displayed on the touch panel 105 (step T8). In addition, since the chemical | medical solution injection device 100 of this form can inject | pour a contrast agent and physiological saline at once as a chemical | medical solution, two chemical | medical solution data are displayed and output in parallel corresponding to two identification data read optically continuously. .
[0070]
At that time, if the chemical type of the first searched chemical data is a contrast medium, the chemical data is displayed and output at the first display position as shown in FIG. It is a contrast medium. Please load it on the right side of the head.
[0071]
Then, if the chemical type of the chemical data searched second is physiological saline, the chemical data is displayed and output as shown in FIG. 7B, and “this chemical is physiological saline. Please load it on the left.
[0072]
On the other hand, if no chemical data is searched (step T3), a confirmation warning such as “The information of this barcode is not registered. T5). In addition, if the searched chemical solution data does not match the confirmation condition (step T4), for example, if the correspondence between the selected imaging region and the searched chemical solution data is not registered, “this site and contrast A combination of agents is not registered. Check the region and contrast agent. A confirmation warning such as “is displayed on the touch panel 105 (step T5).
[0073]
In these cases, the operator confirms the chemical solution syringe 200, and if it is determined that the chemical solution is not appropriate, the operator inputs data reset to the touch panel 105 (step T6). Then, the chemical solution 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 confirmed the chemical syringe 200 determines that there is no problem, for example, when a predetermined operation is performed on the chemical injection device 100, a list of chemical solutions registered as data is displayed on the touch panel 105 (not shown). ). Therefore, when the operator completes the confirmation and selects the desired chemical liquid on the touch panel 105 (step T5), the chemical liquid injector 100 sets the chemical liquid data corresponding to the input operation and displays and outputs it on the touch panel 105 (step T8). ).
[0075]
Therefore, the operator confirms the displayed chemical liquid data. If it is determined that the chemical liquid is not appropriate, a data reset is input to the touch panel 105 (step T9). The injection device 100 erases the set chemical solution data and returns to the initial state (steps T10 and T1).
[0076]
On the other hand, when the operator sets data of the imaging region in the chemical injection device 100, as shown in FIG. 8, a schematic image of a plurality of body sections is displayed and output corresponding to the human body shape on the touch panel 105. 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, a model image of a plurality of imaging regions related to the selected body segment is searched for data (step E2) and displayed below the schematic image of the body segment (step E3). At this time, only the schematic image of the selected body section is brightened and 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 section.
[0078]
Next, when the operator selects one of the plurality of imaging parts (step E4), the selected imaging part is set in a predetermined area of the RAM 133 (step E5), and as shown in FIG. Only one selected schematic image is brightened and the other schematic images are darkened.
[0079]
In the liquid injector 100 of this embodiment, when an imaging region is selected as described above, it is determined whether the imaging region matches the confirmation condition (step E6), and when this matching is also determined, the imaging region Is retrieved from the RAM 133 (step E10).
[0080]
On the other hand, if the imaging region does not match the confirmation condition (step E6), for example, if the correspondence between the set drug solution data and the selected imaging region is not registered, “the combination of this region and the contrast agent” Is not registered. Check the region and contrast agent. A confirmation warning such as “is displayed on the touch panel 105 (step E7).
[0081]
In this case, the operator confirms the imaging region and the chemical syringe 200, and if it is determined that the relationship is not appropriate, the operator inputs data reset to the touch panel 105 (step E9). Then, the medicinal solution injection device 100 returns to the initial state and enters a state of waiting for the body segment selection operation (step E1).
[0082]
On the other hand, when the operator who has confirmed the imaging region and the chemical syringe 200 determines that there is no problem, when the operator inputs a confirmation completion to the touch panel 105 (step E8), the chemical injection device 100 corresponds to the imaging region. Then, the operation condition is retrieved from the RAM 133 (step E10).
[0083]
In the liquid injector 100 of this embodiment, when the operation condition is retrieved as described above, the operation condition is adjusted corresponding to the liquid data (step E11). The adjusted operation condition is set as data, and for example, as shown in FIG. 9, the injection speed, the total injection amount, and the injection time of the adjusted operation condition are displayed and output on the touch panel 105 (step E10).
[0084]
Therefore, the operator confirms the operation condition displayed and output, and if satisfied, presses the “decision” icon on the upper right of the screen with a finger as shown in FIG. 12 (step S5). Then, since the chemical injection device 100 controls the operation of the contrast / saline feeding mechanism 123, 124 under the adjusted operating conditions (step S7), the contrast medium and physiological saline are injected into the subject.
[0085]
In that case, as shown in FIG. 10, the contrast agent is injected into the subject up to the total injection amount in a variable pattern that linearly decreases the injection rate from the start of injection until a predetermined time and thereafter maintains the injection rate constant, and this is completed. Then, a volume of physiological saline proportional to the contrast agent is injected into the subject.
[0086]
[Effect of the embodiment]
In the chemical injection system 1000 of this embodiment, the chemical liquid identification data is recorded in the packing material 204 of the chemical syringe 200 as a barcode, and the chemical injection device 100 storing the chemical liquid data for each of the identification data includes the barcode. The reader 108 reads the identification data from the chemical solution syringe 200, searches for the chemical solution data, and outputs it to the touch panel 105. For this reason, an operator can confirm various data of the chemical | medical solution inject | poured into a test subject easily and reliably, and the medical mistake by which the chemical | medical solution which is not suitable can be inject | poured into a test subject can be prevented.
[0087]
Moreover, when the chemical liquid data is not retrieved from the read identification data, the chemical liquid injection device 100 notifies and outputs a confirmation warning so that the chemical liquid that is not registered is prevented 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, since this is notified and output by a confirmation warning, it is possible to prevent the chemical liquid that does not match the confirmation conditions from being used without being confirmed.
[0088]
Moreover, since the barcode part 205 is formed in the packing material 204 of the chemical | medical solution syringe 200 in this form, chemical | medical solution data can be confirmed, without taking out the chemical | medical solution syringe 200 from the packing material 204, and the chemical | medical solution syringe 200 is packing material. It is also possible to prevent the device from being used while being taken out from 204.
[0089]
In addition, since the chemical injection device 100 according to the present embodiment controls the operation of the contrast / sacrifice injection mechanisms 123 and 124 corresponding to the searched chemical solution data, the chemical injection device 100 corresponds to the chemical without requiring a complicated input operation. The injection operation can be performed easily and reliably.
[0090]
In particular, the liquid injector 100 according to the present embodiment sets an operation condition corresponding to the selection operation of the imaging region of the subject and adjusts the data corresponding to the liquid data, thus requiring a complicated input operation. Therefore, the injection operation corresponding to the drug solution and the imaging site can be executed easily and reliably.
[0091]
In addition, a schematic image of a plurality of body sections is displayed and output on the touch panel 105 in the shape of a human body, and when one of them is selected and operated, a schematic image of a plurality of corresponding imaging regions is displayed and output, and one of them is selected and operated. Since the corresponding operation conditions are retrieved and set, the operation conditions for each imaging region can be set with extremely simple operations.
[0092]
Furthermore, whether or not the correspondence relationship between the chemical solution data searched for data and the selected imaging part is automatically confirmed, and if this is inappropriate, a notification warning is output, so that an imaging that is not appropriate for the imaging part is performed. It is possible to prevent the agent from being injected.
[0093]
Moreover, in the chemical injection device 100 of the present embodiment, the contrast medium and physiological saline are injected into the subject by the contrast / saline injection mechanism 123, 124, but the interlocking is also automatically executed according to the operating conditions, which is complicated. The contrast medium and the physiological saline can be injected appropriately in conjunction with the subject without requiring any operation.
[0094]
Furthermore, in the liquid medicine injection device 100 of this embodiment, the contrast agent injection speed is changed with time corresponding to the variable pattern, so that the CT value can be maintained close to the optimum value, and the CT scanner 300 can be maintained. An optimal fluoroscopic image can be taken. Moreover, since the amount of contrast medium used can be minimized, it is possible to save the contrast medium and contribute to the health of the subject.
[0095]
As shown in FIG. 10, an experiment was performed in which the contrast medium was injected in a variable pattern that linearly decreases the injection rate from the start of injection to a predetermined time and thereafter maintains the injection rate constant. As shown, it was confirmed that the state in which the CT value approximates the optimum value is maintained for a long time.
[0096]
The variable pattern as described above is different for each imaging region, and the setting and operation thereof is complicated. However, the chemical injection device 100 according to the present embodiment allows the operator to set the body classification and the imaging region in a schematic image. If an appropriate variable pattern is selected, a complicated operation can be executed with an extremely simple operation.
[0097]
[Modification of Embodiment]
The present invention is not limited to the above embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, the liquid injection device 100 having the contrast / saline injection mechanisms 123 and 124 as the injection head 110 is illustrated as injecting the contrast medium and the physiological saline. A chemical solution injection device (not shown) for injecting can also be implemented.
[0098]
In the above embodiment, the barcode part 205 is formed on the packing material 205 of the chemical syringe 200. However, the barcode part 205 can 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 bar code unit 205, it is also possible to record this with a magnetic stripe, an IC (Integrated Circuit) chip, the outer shape of the cylinder member 201, or the like. .
[0099]
Moreover, although the chemical liquid identification data was recorded on the chemical | medical solution syringe 200 in the said form, and various chemical | medical solution data was registered for every identification data in the chemical | medical solution injection apparatus 100, for example, chemical | medical solution is stored in the chemical | medical solution syringe 200, for example. It is also possible to record the data directly.
[0100]
Further, in the above embodiment, the chemical injection system 100 is exemplified by the chemical syringe 200 exchangeable with the chemical injection apparatus 100. However, the chemical injection system is constituted by the chemical syringe 200 exchangeable with the chemical injection apparatus 100 and the chemical thermal insulation device. It is also possible (not shown).
[0101]
The chemical solution heat retention device includes a case for storing a plurality of chemical solution syringes 200, and has a heat retention execution mechanism for maintaining the stored chemical solution syringes 200 at a predetermined temperature appropriate for the chemical solution. Therefore, it is possible that such a chemical solution heat retention apparatus includes a data storage unit 141, a barcode reader 108, a data search unit 142, and a data display unit 143.
[0102]
In this case, since the chemical liquid data can be confirmed when the chemical liquid syringe 200 is kept warm by the chemical liquid heat retaining apparatus, the chemical liquid data can be confirmed before the chemical liquid syringe 200 is loaded into the chemical liquid injector 100. Furthermore, it is possible to appropriately keep the chemical syringe 200 warm by controlling the operation of the heat retention execution mechanism in response to the identification data and the chemical solution data by the chemical solution warming device as described above.
[0103]
In addition, the chemical solution heat retaining device can include the data storage unit 141, the barcode reader 108, and the data search unit 142, and the chemical solution injection device 100 can include the data display unit 143. It is possible that the chemical injection device 100 has the reader 108 and the data storage unit 141, the data search unit 142, and the data display unit 143.
[0104]
In these cases, when the bar code portion 205 of the chemical syringe 200 is optically read by the chemical solution heat retention device, the chemical solution data is displayed on the chemical solution injection device 100. You can check before loading.
[0105]
In the above embodiment, the barcode reader 108 is integrally incorporated in the injection device main body 103 of the chemical solution injection device 100. However, the handy barcode reader is wired or wirelessly connected to the chemical solution injection device 100 or the chemical solution heat retention device. It is also possible to connect to (not shown).
[0106]
Furthermore, as shown in FIG. 15, a barcode reader 108 and a touch panel 105 can be provided in parallel with the injection head 110 of the chemical injection device 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 chemical syringe 200 is loaded, these can be executed intuitively.
[0107]
In the above embodiment, the case where the injection of the contrast medium and the physiological saline is linked according to the operating condition is exemplified. However, the operating condition can be set in various data as desired. For example, as the applicant has filed as Japanese Patent Application No. 2002-363675, it is possible to inject the contrast medium while diluting with physiological saline according to operating conditions.
[0108]
In that case, since the appropriate iodine concentration differs depending on the contrast agent and the imaging region, conventionally, the contrast agent is changed every time the imaging region is changed. However, in the liquid injector 100 according to the present embodiment, when the barcode part 205 of the liquid syringe 200 for contrast medium is optically read and an imaging part is selected and operated, the contrast agent is appropriately diluted corresponding to the imaging part. The condition is set as data.
[0109]
For this reason, if a high-concentration contrast agent is loaded in the drug solution injection device 100 together with physiological saline, various imaging sites can be appropriately contrasted and imaged without replacing the contrast agent. Work burden can be reduced. In addition, since the iodine concentration can be freely varied by diluting the contrast agent with physiological saline, the contrast agent can be injected into the subject at an iodine concentration not present in commercially available products. Although manual operation of such dilution is complicated, the drug solution injection device 100 according to the present embodiment can appropriately dilute the contrast agent with an extremely simple operation as described above.
[0110]
Moreover, although the chemical | medical solution injection apparatus 100 illustrated adjusting the operating conditions for every imaging region according to chemical | medical solution data in the said form, for example, test subject's body data, such as a body weight, a body type, age, and sex, are also chemical injection. It is also possible to input to the device 100 and adjust the operating conditions corresponding to the body data.
[0111]
Furthermore, in the above embodiment, the operation condition is registered for each imaging region and is adjusted corresponding to the chemical liquid data. For example, the operation condition is registered for each imaging region for each chemical liquid data. It is also possible to register the operating conditions for each chemical solution data and adjust it according to the imaging region.
[0112]
In the above embodiment, it is exemplified that new drug solution data is downloaded from the PC card 106, which is an information storage medium, to the drug solution injection device 100. However, it is also possible to download operating conditions in the same manner. Various products can also be used. Furthermore, the chemical solution injection device 100 can retrieve data from the loaded PC card 106 in real time without copying the chemical solution data or the like from the PC card 106 to the RAM 133.
[0113]
It is also possible for the chemical solution injection device 100 to be connected online to a device manufacturer or a host computer of the chemical solution manufacturer via a communication network such as the Internet, so that the chemical solution injection device 100 can download the chemical solution data and operating conditions online.
[0114]
Further, in the above embodiment, it is assumed that the chemical solution injection of the chemical solution injection device 100 and the image pickup of the CT scanner 300 are performed manually and individually, but the present applicant has filed as Japanese Patent Application No. 2003-069870. In addition, the chemical liquid 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 apparatus, and the chemical injection device 100 injects the CT contrast agent. For example, an MRI apparatus or a PET apparatus is used as the fluoroscopic imaging apparatus, It is also possible to inject a contrast medium therefor by a chemical liquid injector.
[0116]
Moreover, in the said form, it was illustrated that various means are logically implement | achieved as various functions of the chemical | medical solution injection apparatus 100, when CPU131 operate | moves corresponding to the computer program stored in RAM133 grade | etc.,. However, each of these various means can be formed as unique hardware, and a part can be stored in the RAM 133 or the like as software, and a part can be formed as hardware.
