A syringe driver, also known as a syringe pump, is a small battery-powered pump used to give gradual fluids and medicines via a needle just under the skin.[2] It is frequently used to administer pain relief and anti-sickness medicines to control symptoms in end of life care.[2][1]

Uses

Syringe drivers can be used for electrospinning, electrospraying, microdialysis, microfluidics, dispensing/dilution, tissue perfusion, and fluid circulation. It may be used in chemical and biomedical research. Some syringe drivers can both infuse and withdraw solutions.

Intravenous therapy

Syringe drivers are useful for delivering intravenous (IV) therapies over several minutes. They infuse solutions at a constant rate.[3] In the case of a medication which should be slowly pushed in over the course of several minutes, this device saves staff time and reduces medical errors. It is useful for patients who cannot take medicines orally (such as those with difficulty swallowing), and for medications too harmful to be taken orally.[4]

Palliative care

It may be used to administer pain relief and anti-sickness medicines in end of life care.[2] This prevents periods during which medication levels in the blood are too high or too low, and avoids the use of multiple tablets. As medication is administered subcutaneously, the area of administration is practically limitless, although edema may interfere with the action of some drugs.

Research

Syringe pumps are useful in microfluidic applications, such as microreactor design and testing, and also in chemistry for slow incorporation of a fixed volume of fluid into a solution. In enzyme kinetics studies, syringe drivers can be used to observe rapid kinetics as part of a stopped flow apparatus.[5] They are also sometimes used as laboratory media dispensers.
