- the data communication member Z units 140 and 230 since the electric signal is converted into the ultrasonic signal and transmitted as described above, the transmission direction of the electric signal can be reliably restricted. . Therefore, in the data communication member Z units 140 and 230 of the present embodiment, for example, even if noise or the like enters the lower Z upper receivers 142, 144, 233, and 238, the noise is transmitted to the upper Z lower transmitters 141 and 230. Malfunction of the chemical liquid injector 100 and the MRI apparatus 200 that cannot return to 143, 232, and 237 can be reliably prevented.
- the present invention is not limited to the above-described embodiment, and allows various modifications without departing from the gist thereof.
- the force MRI apparatus 200 and the chemical liquid injector 100 exemplify that the MRI apparatus 200 and the chemical liquid injector 100 individually operate independently. is there.
- the chemical injection device 100 and the MRI device 200 are connected to each other. Can perform data communication that does not generate electromagnetic wave noise and is not affected by electromagnetic wave noise.
- the data communication member 140 having the upper Z lower transmitters 141 and 143 and the upper Z lower receivers 144 and 142 allows the injection control unit 101 and the injection head 110 of the liquid injector 100 to communicate with each other. Communicating has been illustrated. However, it is also possible to execute only one data communication from the injection control unit 101 to the injection head 110 by a data communication member (not shown) having only the upper transmitter 141 and the lower receiver 142.
- first Z second communication media 146, 147, 241, 242 are sealed in the first Z second tube chambers 151, 152 and the first Z second closed containers 251, 252 of the tube member 150.
- first and second communication media are inserted, for example, it is also possible to form such a first Z second communication medium with a resin mass (not shown).
- the MRI apparatus 200 is used as a fluoroscopic imaging apparatus, and the liquid injector 100 injects a contrast agent for MR as a chemical liquid.
- the liquid injector 100 injects a contrast agent for MR as a chemical liquid.
- a CT scanner or PET is used as a fluoroscopic imaging apparatus. It is also possible to use a device or an ultrasonic diagnostic device, etc., and to inject a contrast agent or the like for the device into the liquid injector.
- the CPU 131 operates in accordance with the computer program stored in the RAM 133 or the like, so that various functions of the drug solution injector 100 are provided. Is logically realized. 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.
- a force is used to exemplify the liquid injector 100 in which only one liquid syringe 200 is mounted on the injection head 110.
- the liquid injector 100 in which only one liquid syringe 200 is mounted on the injection head 110.
- a liquid injector 500 in which the liquid syringe 200 is mounted on the injection head 530, and a liquid injector (not shown) in which three or more liquid syringes 200 are mounted on the injection head can be implemented.
- the injection control unit 101 of the liquid injector 100 and the injection head 110 are directly connected by the data communication member 140, and all of them are MRI. It is illustrated that the apparatus 200 is arranged in the treatment room 301 together with the fluoroscopic imaging unit 201 of the apparatus 200.
- the injection head 110 is generally disposed in the treatment room 301, and the injection control unit 101 is generally disposed in the operation room 302. It is. Therefore, such a configuration is briefly described below with reference to FIG.
- a communication cable 501 that is not magnetically shielded is connected to the injection control unit 101, and the communication cable 501 is connected to one end of a second data communication unit 230 embedded in the partition wall 300.
