Technical Field

The utility model relates to the related field of medical equipment, in particular to an anti-falling epidural anesthesia catheter connector.

Background

Epidural anesthesia is a common clinical anesthesia technique, and is characterized by that a catheter is inserted into proper interspinous space of spinal column, and local anesthetic nerve block is injected into the epidural space by means of catheter so as to attain the action of paralyzing its correspondent dominant region. The operation is similar to the epidural anesthesia, and the catheter is inserted and inserted into the specific spinous process space, but longer in-vivo retention time is required, usually 7-10 days, during which the medicine is injected into the epidural space through the catheter every day, so that the catheter adapter is used more frequently than the epidural anesthesia.

The joint of the conduit and the joint is mainly characterized in that the joint is fixed by extruding the conduit when the joint is screwed by a rubber ring arranged in the joint, so that the effects of fixing the conduit and preventing the liquid medicine from overflowing are achieved. In clinic, the joint is screwed too tightly to cause flattening of the catheter and can not be filled with liquid medicine, the joint is not screwed tightly or the joint is frequently used to cause loosening of the joint and the catheter, then the liquid leakage or the catheter falling off can be caused by injecting medicine into the joint, and for the continuously-dosed treatment patients of the epidural external catheter, the catheter can fall off from the joint frequently in daily life such as putting on and taking off clothes of the patients due to long-time retention of the catheter, and once the front end of the falling-off catheter contacts with a non-cleaning area, the risk of epidural infection is extremely high, so that inconvenience is brought to clinical treatment work.
