[0003] The patent with publication number CN221243636U discloses an anesthetizing catheter with adjustable anesthesia flow, which includes an anesthetizing catheter body. The anesthetizing catheter body includes a main pipe body, a mounting head, and a plug. The mounting head is arranged at one end of the main pipe body, and the plug is arranged at the other end of the main pipe body. By designing a flow adjusting machine, the device is stably connected through the deformation of the elastic pad and is convenient for tight compression to control the anesthesia flow of the anesthetizing catheter body. When the main pipe body is pulled, it is not easy to cause loosening, and the adjustment of anesthesia flow is more stable, improving the stability of the anesthetizing catheter body when adjusting anesthesia flow.

[0004] However, the device uses a threaded rod, a rotating ring, and a moving pressure plate to extrude the anesthetizing catheter body, thereby changing the flow. Directly extruding the anesthetizing catheter body, the cross-section of the extruded part of the anesthetizing catheter will become irregular, making it difficult to accurately control the extrusion degree according to the required anesthesia flow, so that the flow through the anesthetizing catheter is suitable for patients, thereby affecting the anesthesia effect of patients. Therefore, an anesthetizing catheter with adjustable anesthesia flow is proposed to solve the problem of the existing anesthetizing catheter that is difficult to accurately control the anesthesia flow according to the patient's condition.
