Abstract

The invention provides a flexible injury-preventing spiral steel wire reinforced anesthetic catheter and a preparation method thereof. The anesthetic catheter comprises a catheter and a catheter joint, the catheter comprises a catheter body and a catheter head, one end of the catheter body is connected with the catheter joint in an insertion manner while the other thereof is connected with the catheter head, the catheter head gradually becomes from soft to hard from the front end of the catheter head to the catheter body, a spiral steel wire is arranged in the wall of the catheter body, and a plurality of medicine outlet holes are formed in the end, connected with the catheter head, of the spiral steel wire. The flexible injury-preventing spiral steel wire reinforced anesthetic catheter has the advantages that the anesthetic catheter is reasonable in structure and novel in design, and the flexible catheter head can bend and put into the body easily without injuring tissues and endorhachis easily, so that operative complications are avoided; the spiral steel wire is arranged inside the catheter body and cannot be compressed during use, so that a smooth passage and good anesthetic effects are achieved; the anesthetic catheter is capable of protecting spinal epidural cavity nerves from being compressed after being put into the body, thereby being high in safety and comfort level.

Description

technical field

[0001] The invention belongs to the technical field of medical anesthesia apparatus, and in particular relates to a flexible anti-damage spiral steel wire reinforced anesthesia catheter and a preparation method thereof. Background technique

[0002] The epidural nerve block in the prior art is a widely used anesthesia method in clinical practice, and has the advantages of simple operation, low cost, easy management during the operation, and convenient epidural analgesia after the operation. The main component is the anesthesia catheter. The traditional anesthesia catheter is made of a transparent catheter and a catheter connector. Since the catheter is made of plastic, it is easy to be crushed or folded into a dead angle during operation, resulting in the passage being blocked and the anesthesia effect is poor. When the hardness of the catheter material is high, the catheter It is easy to be inserted into the human body, but the flexibility is poor, and it i...
