CHEMICAL LIQUID INJECTION SYSTEM
First Claim
1. :
- A chemical liquid injection system at least comprising;
a liquid syringe including a cylinder member filled with a liquid and a piston member slidably inserted into the cylinder member; and
a chemical liquid injector for injecting the liquid into a patient by relatively moving the cylinder member and the piston member of the liquid syringe replaceably mounted thereon, using a liquid injection mechanism,wherein the liquid syringe has data storing means on which at least liquid-identification data for the filled liquid is recorded, andthe chemical liquid injector includes;
liquid data acquiring means for acquiring the liquid-identification data from the data storing means;
patient chart data acquiring means for acquiring data on contra-indicated liquid from an external electronic chart, wherein at least identification data for the contra-indicated liquid for injection are registered as the data on contra-indicated liquid in the electronic chart for each of the patients;
data comparing means for comparing the acquired liquid-identification data and the acquired data on contra-indicated liquid; and
alarm notifying means for notifying an alarm when the liquid-identification data matches the data on contra-indicated liquid.

Abstract
The present invention provides a chemical liquid injection system in which a chemical liquid injector can detect whether or not the injection of a liquid from a liquid syringe into a patient is inappropriate for a personal reason such as the development of a side effect although the liquid is of an appropriate type for the injection system, and the chemical liquid injector can issue an alarm to notify the inappropriate injection. Chemical liquid injector 100 acquires a product ID of the liquid recorded on liquid chip 214 of liquid syringe 200 and an inappropriate ID recorded in a electric chart to output a notification when the product ID matches the inappropriate ID.

29. :
- A chemical liquid injection system comprising;
(a) a liquid syringe comprising a cylinder member to be filled with a liquid and a piston member slidably inserted into the cylinder member, said liquid syringe being configured to store liquid-identification date for the liquid; and (b) a chemical liquid injector for injecting the liquid into a patient by relatively moving the cylinder member and the piston member of the liquid syringe mounted thereon, said chemical liquid injector comprising; a liquid-identification data reader for acquiring the liquid-identification date from the liquid syringe; a patient data reader for acquiring data on contra-indicated liquid from an external electronic chart for the patent; a data comparing unit for comparing the liquid-identification date and the date on contra-indicated liquid; and a notifying device for notifying an outcome from the date comparing unit when the liquid-identification date are matched to the date on contra-indicated liquid.
