Anesthesia Epidural Needle Adjustment System

Abstract

The invention belongs to the technical field of anesthesia appliances, in particular to an anesthesia epidural needle adjustment system, comprising a first support block and a second support block, a tube base is arranged on one side of the first support block, and a cylinder is stuck inside the tube base , a needle tube is installed in the barrel, an anesthesia catheter is connected inside the needle tube, a sliding seat is integrally formed on one side of the tube seat, and a fixed block is inserted in the position close to the sliding seat in the tube seat, and the medical staff can place the thumb on it. Above the pressing block, through the relative slidability between the No. 1 slider and the first support block under the slider and the mobility of the No. 2 slider in the second support block, combined with the action of external force, the anesthesia catheter and The position adjustment of the injection assembly composed of the needle tube and other components also enables the medical staff to have better control over the process. Through the double limit function of the connecting rod and the perforation in the second slider, the puncture process of the needle tube is not easy. Offset occurs.

Description

technical field [0001] The invention belongs to the technical field of anesthesia appliances, and in particular relates to an anesthesia epidural needle adjustment system. Background technique [0002] Anesthesia is a common method in modern medical operations. In the process of clinical anesthesia for epidural block, 1% lidocaine needs to be injected into the skin, subcutaneously, and interspinous ligament gradually during the operation from the median approach. The anesthesia epidural needle system composed of corresponding needle tubes, anesthesia catheters, and epidural needles is used to determine the injection location and deliver the drug. During the process, there is no more adjustability; the fixed injection position requires the patient to move by himself, so that the medical staff has no good control over it; there is no corresponding positioning structure for the needle tube during puncture, making it Puncture deviation is easy to occur; when the needle tube nee...

[0002] Anesthesia is a common method in modern medical operations. In the process of clinical anesthesia for epidural block, 1% lidocaine needs to be injected into the skin, subcutaneous, and interspinous ligament step by step during the operation from the median approach. The anesthesia epidural needle system composed of corresponding needle tubes, anesthesia catheters and epidural needles is used to determine the injection location and deliver the drug. During the process, there is no more adjustability; the fixed injection position requires the patient to move by himself, so that the medical staff has no good control over it; there is no corresponding positioning structure for the needle tube during puncture, which makes it It is easy to produce puncture deviation; when the needle tube needs to be pulled out later, there is no relatively stable pull-out auxiliary member for the needle tube, which reduces the working efficiency of the medical process to a certain extent
