具体实施方式Detailed ways
实施例：Example:
如图1所示，一种局部麻醉针，包括针管1和雾化喷头9，所述针管1和雾化喷头9之间设有软管8，所述针管1内设有套管2，所述套管2上设有针头12，所述雾化喷头9设有容针头12通过的过孔10，所述套管2内设有第一推杆3和第一活塞7，所述针管1与套管2之间设有第二推杆4和第二活塞6，所述第一推杆3与第二推杆4套接，所述套管2侧壁设有若干小孔11，所述第二活塞6靠近套管2一侧设有密封套5。As shown in Figure 1, a local anesthesia needle includes a needle tube 1 and an atomizing nozzle 9, a flexible pipe 8 is provided between the needle tube 1 and the atomizing nozzle 9, and a sleeve 2 is arranged inside the needle tube 1, so The sleeve 2 is provided with a needle 12, the atomizing nozzle 9 is provided with a through hole 10 for the needle 12 to pass through, the sleeve 2 is provided with a first push rod 3 and a first piston 7, and the needle 1 A second push rod 4 and a second piston 6 are arranged between the sleeve 2, the first push rod 3 is socketed with the second push rod 4, and the side wall of the sleeve 2 is provided with several small holes 11, so A seal sleeve 5 is provided on the side of the second piston 6 close to the casing 2 .
所述小孔11为弹性孔，在一定压力下麻醉药液于小孔11溢出，所述针管1外壁设有刻度线。The small hole 11 is an elastic hole, and the anesthetic liquid overflows from the small hole 11 under a certain pressure, and the outer wall of the needle tube 1 is provided with a scale line.
本实用新型在使用时，在套管2内注入麻醉药液，可以推动第一推杆3和第二推杆4，麻醉药液于小孔11溢出，通过软管8进入雾化喷头9，同时实现注射麻醉和雾化麻醉或只进行雾化麻醉。先推动第二推杆4密封套5包住小孔11，麻醉药液不溢出，这样可以只进行注射麻醉。结构简单，使用方便，不容易给患者造成疼痛感，给医务人员减少工作难度。When the utility model is in use, the anesthetic liquid is injected into the casing 2 to push the first push rod 3 and the second push rod 4. The anesthetic liquid overflows from the small hole 11 and enters the atomizing nozzle 9 through the hose 8. Simultaneously achieve injection anesthesia and nebulization anesthesia or only nebulization anesthesia. First promote the second push rod 4 sealing sleeve 5 to encase the small hole 11, so that the anesthetic liquid does not overflow, so that only injection anesthesia can be performed. The utility model has the advantages of simple structure and convenient use, is not easy to cause pain to patients, and reduces work difficulty for medical personnel.
