Accessory devices for sterile single-use intravascular catheters -
Part 3: Inflation devices for balloon of balloon dilatation catheters
1 Scope
This part of YY/T 0450 specifies the requirements of single-use manual inflation device for intravascular balloon dilatation catheters (hereinafter referred to as "inflation device"). This product is suitable for inflating the balloon of balloon dilatation catheter specified in YY 0285.4, so as to inflate it to expand the blood vessel or release the stent.
The release device of intravascular occlusion and the inflation device of balloon occlusion catheter have similar structures to the inflation device specified in this part, to which this standard does not apply.
