Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an intermittent drug administration analgesia pump with adjustable drug concentration.
Background
At present, when painless childbirth or intraspinal surgery is performed, local anesthetic with proper concentration is needed to be applied to the affected part through epidural, the concentration of the local anesthetic is too high, the motor function of a patient is blocked, the effect of the surgery can be affected, and the risk of damaging motor nerves due to the surgery is greatly increased; or the muscle contraction function of the puerpera is influenced, so that the labor capacity is insufficient, the labor process is prolonged, and even the spontaneous labor fails to increase the probability of cesarean section operation. When the local anesthesia concentration is too low, pain is likely to occur to the patient due to incomplete sensory nerve block, and even the anesthesia fails due to severe pain. Because of individual difference, the optimal concentration of the anesthetic for patients needs to be far away, and the satisfactory concentration ratio of the anesthetic for the epidural analgesia pump is difficult to achieve by the experience of an anesthesiologist. At this stage, the effect of such anesthetics, either deep or shallow, is difficult for the patient or physician to satisfy. There is a clinical urgent need for an epidural analgesia pump that can regulate local anesthetic concentration.
Meanwhile, continuous slow low-flow administration is very forbidden when epidural anesthesia is administered, and the administration method usually causes the anesthesia plane to be smaller and smaller, the anesthesia blocking range to be narrower and narrower, and finally even causes anesthesia failure. The relatively proper epidural anesthesia administration method is that local anesthesia medicines with relatively large capacity are administered at one time at relatively long intervals, so that the medicine administered each time can be expanded to a relatively wide range, the anesthesia plane is ensured to be unchanged, and the increasingly narrow anesthesia plane caused by the increasingly concentrated anesthesia is avoided.
