Description

Analgesic pump's medicine delivery structure convenient to charge

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a drug delivery structure of an analgesic pump convenient for drug addition.

Background

Epidural anesthesia refers to epidural space block anesthesia, i.e., the injection of local anesthetics into the epidural space to block the spinal nerve roots, temporarily paralyzing its innervating areas, known as epidural space block anesthesia. At present, pumps for epidural delivery analgesia mainly comprise two types, namely a program-controlled epidural intermittent pulse analgesia pump and a common electronic analgesia pump, and a doctor connects the configured analgesia pump with an epidural catheter through a conveying pipe to relieve pain for a puerpera. The pain generated by women in the childbirth process is fluctuant, when severe pain occurs in the childbirth process, namely 'pop pain', the local anesthetic concentration in the analgesic pump can not meet the requirement of analgesia, and a doctor is required to reconfigure the higher concentration of the local anesthetic to be injected into the vertebral canal of a patient through an epidural catheter to achieve the purpose of analgesia.

At present, when a doctor injects the reconfigured local anesthetic into the vertebral canal of a patient, the doctor firstly needs to separate the joint of the epidural catheter joint and the analgesic pump delivery pipe to inject the local anesthetic from the epidural catheter joint, and then needs to be reconnected and fixed after the medicine is added. In the first labor with average length of 12 hours, repeated severe pain can occur to individual puerperae, so that doctors are required to add local anesthetic for relieving pain for many times, and even when the caesarean section is transferred in the failure of the normal labor, more local anesthetic is required to be added to meet the operation requirement. At this time, the joint of the epidural catheter and the delivery pipe of the analgesic pump are repeatedly separated, connected and fixed, so that the workload of doctors is increased, and in a non-sterile environment of an obstetric room, external pathogenic microorganisms can enter the vertebral canal from the epidural catheter more easily, so that the probability of infection is greatly increased.

It is therefore necessary to design a delivery structure for an analgesic pump that facilitates administration of the drug.
