Insulin syringe, as the name suggests, is a syringe specially used to inject insulin. It is usually composed of four parts: needle cap, injection needle, syringe, and pusher.
The reason why a special syringe is used for insulin injection can not be replaced by an ordinary syringe because the scale units marked on the two are different. The scale marked on the insulin special syringe is insulin units, while the scale on the ordinary syringe is milliliters. The smallest unit of an ordinary syringe is usually 0.1 ml, which is equivalent to 4 units of insulin after conversion, and most patients need to inject insulin doses that are not an integer multiple of 4. Therefore, if an ordinary syringe is used, not only does the patient need to convert the dose and volume, but it is also difficult to accurately extract the required dose.
