Technical Field

The utility model relates to the technical field of medical equipment, in particular to an anesthesia pump for the department of anesthesia medicine.

Background

Anesthesia is generally considered to be a reversible functional inhibition of the central and/or peripheral nervous system, produced by drugs or other means, which inhibition is characterized primarily by a loss of pain sensation. Patient self-control analgesia is a new treatment method proposed by Sechzer in the early 70 s, and is mainly used for postoperative pain, late cancer pain treatment and postpartum analgesia. Can be used for treating acute and chronic pain. The drug in an anesthetic pump (also known as a pain relief pump) is typically an anesthetic.
