3 Terms and definitions
For the purpose of this document, the following terms and definitions and those defined
in GB/T 10149 apply.
3.1
angiographic injector
The injector used to rapidly inject a sufficient amount of contrast agent to the inspection
site in a certain period of time, in the diagnosis or treatment of vascular intervention
angiography, in order to obtain the required medical image with the use of X-ray
angiography equipment.
3.2
injector head
The part equipped with injection push mechanism and supporting syringe.
3.3
flow rate
The dosage of the contrast agent injected per unit of time, in milliliters per second
(mL/s).
3.4
rise time
The time taken from the start of the injection to when it reaches the set flow rate, in
seconds.
3.5
maximum injection pressure
The maximum pressure that can be reached at the time of injection of an injector.
3.6
pressure limit
The maximum allowable pressure during injection of an injector.
3.7
injection delay
After receiving the start signal, the injector starts the injection after a set delay time.
3.8
X-ray delay
After pressing the injection switch, the injector sends out the trigger signal after a set
delay time.
3.9
fill rate
b) power supply frequency. 50 Hz ± 1 Hz.
6.2 Flow rate
The test medium is distilled or deionized water. The injection dose is set to 100 mL,
and the flow rate is set to the minimum value and 50 % of the maximum value
respectively. When it is set to the maximum value, use a timer (such as synchronized
stopwatch) to count the time taken from the start to the end of the injection, use a
balance to weigh the distilled water and convert it to capacity, calculate the flow rate
deviation, which shall meet the requirements of 5.2.
6.3 Injection dose
The test medium is distilled or deionized water. SET the injection dose to 2 mL (when
the flow rate is the minimum value), 20 mL (when the flow rate is 50 % of the maximum
value) and 40 mL (when the flow rate is the maximum value); USE a balance to weigh
the distilled water and convert it to capacity; CALCULATE the injection dose deviation,
which shall meet the requirements of 5.3.
6.4 Fill rate
The test medium is distilled or deionized water. USE a timer to count the time taken
from the start to the end of the filling signal; DETERMINE the capacity of the filled
injection agent by weighing the weight of the container before and after filling;
CALCULATE the fill rate, which shall meet the requirements of 5.4.
6.5 Maximum injection pressure
SET the pressure limit to the maximum value of the injector; USE a connector to
connect the syringe and the pressure gauge; INJECT in a flow rate of 3 mL/s; READ
the pressure the injector indicates when it exceeds the pressure limit and stops the
injection; CALCULATE the deviation between the actual pressure and the maximum
injection pressure, which shall meet the requirements of 5.5.
6.6 Pressure lim......
