Final answer:
An insulin syringe is a type of syringe that has no dead space and is divided into units for precise medication dosing, often used in the management of diabetes.
Step-by-step explanation:
The type of syringe you are referring to, which does not have dead space and is divided into units, is known as an insulin syringe. Dead space is the volume of a syringe that is leftover after the plunger has been fully depressed; it can lead to medication waste and is undesirable in precise dosing scenarios, such as insulin administration. Insulin syringes are designed to minimize or eliminate this dead space and often have graduated markings in units to ensure accurate dosing for patients managing diabetes.
