What is the definition or description of: pain pump?

See below: An intrathecal pump is a medical device used to deliver very small quantities of medications directly to the spinal fluid of a human being. Medications such as baclofen, morphine, or ziconotide may be delivered in this manner to minimize the side effects often associated with the higher dosages commonly found in oral medications of the same type.

Patient control analgesia (pca) is a modern way of treating pain in post surgical hospital patients if other options do not work.

Pain pump: Pain pumps are electric, battery powered or newer spring loaded devices used to administer pain medications.
