Cost is cheap, is easily managed in art, postoperative the advantages that being easy to Epidural analgesia, and critical piece used in this anesthesia is
Anesthetic tube.Traditional anesthetic tube is formed by transparent conduit and pipe joint grafting, because conduit is plastic material, during operation
Dead angle is easily crushed or be converted into, causes path to be closed, anaesthetic effect is poor；When the hardness of conduit material is high, conduit is easy to
Human body is inserted, but flexibility ratio difference easily stabs tissue blood vessel, nerve or even breaks endorchis, and there is the phenomenon damaged particularly in blood vessel
Prominent, security is poor；When the hardness of conduit material is low, flexibility ratio is high, but conduit is not easy to insert spinal epidural cavity, also,
It is easily bent or even knots after inserting, causes conduit not take out, operation is wasted time and energy；What segmental epidural catheter was finally inserted
Epidural intraluminal tissue it is soft and rich in nerve, easy compressing spinal epidural cavity nerve after conventional catheters are inserted causes patient
Comfort level it is poor.
The spiral wire of the wire reinforced conduit of conventional helical directly contacts with decoction, because spiral wire winding process needs
Mineral oil lubrication is added, needs to carry out complicated cleaning, drying course to spiral wire crack before producing conduit, and is difficult to clean,
Easy laying dust pollution between spiral wire and sleeve pipe in production process, finally enters human body spinal cavity with decoction and produces many sequelae.
Spiral wire directly contacts with decoction, its rough surface, is unfavorable for liquid medicine flow, and flow reduces, and decoction presss from both sides into spiral wire
In seam, residual quantity is not easy to control.
