[0002] Anesthesia catheters play a vital role in medical surgery, especially in situations where the flow of anesthetics needs to be precisely controlled. Anesthesia means using drugs or other methods to temporarily make the patient lose all or part of their sensation in order to achieve painless surgical treatment.

[0003] Since the anesthetic flow rate of a traditional anesthesia catheter is difficult to control, this may lead to unstable anesthetic effects, either insufficient anesthesia affecting the operation, or excessive anesthesia causing adverse effects on the patient's body. Therefore, technical personnel in this field provide an anesthesia catheter with adjustable anesthetic flow to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and an anesthesia catheter with an adjustable anesthesia flow rate is proposed. By setting an adjusting rod, a regulating valve and adjusting holes of different sizes, the adjusting rod is rotated to drive the regulating valve to rotate, and the relative position of the regulating hole and the internal channel of the guide tube is changed, so as to adjust the flow area of ​​the anesthetic liquid to achieve flow regulation. By adopting a three-layer composite protective structure of nylon, polyurethane and silicone, it is ensured that there is no adverse effect on contact with the anesthetic liquid and it is more comfortable to use. This multi-layer composite protective structure not only improves the durability of the catheter, but also improves the safety and comfort of use. By adopting a flange connection method, two sets of flanges are fastened by bolts and nuts to connect the anesthesia catheter.
