The utility model provides a anesthesia needle for the anesthesiology, which belongs to the field of medical instruments in the anesthesiology department. It solves the problem that the existing anesthetic needles can not be easily adjusted. The Department of Anesthesiology anesthesia needle, including having a circular pinhole inside the needle, the outer needle sleeve with a transparent protective cap, pin hole wall is provided with an annular groove and a coaxial needle, and further comprises a needle in the adjusting sleeve, a regulating sleeve is embedded in an annular groove, a regulating sleeve wall section is non-circular structure, side wall and adjusting needle a wall are respectively provided with a plurality of liquid outlet holes and a plurality of liquid outlet holes two, a regulating rod is fixed on the protective cap, the adjusting rod is arranged with the regulating sleeve, and by rotating around the axis of the needle protecting cap, to drive through adjusting rod rotating, using liquid Kong Yi and a liquid outlet hole two, aligned dislocation both overlap or control. The anesthesia needle controls the size of the openings according to the need, and the adjustment is very convenient. At the same time, the use of the cap adjustment can also avoid the contamination of the needle, and the cap has good protective effect.
【技术实现步骤摘要】
一种麻醉科麻醉针
本技术属于麻醉科医疗器械
,涉及一种麻醉科麻醉针。
技术介绍
临床上对患者手术时经常需要使用注射器和麻醉针做局部麻醉。目前的麻醉针一般为普通的注射针,麻醉药扩散较慢,经常需要反复进行多次穿刺才能起到麻醉效果;还有一种麻醉针是在尖端部位开有侧孔,由于侧孔大小是固定的,不能根据人体组织的吸收情况进行调节,起不到较好的麻醉效果。
技术实现思路
本技术的目的是针对现有技术中存在的上述问题,提供了一种方便调节开孔大小,且能一次实现多点注射的麻醉科麻醉针。本技术的目的可通过下列技术方案来实现:一种麻醉科麻醉针,包括内部具有圆形针孔的针头,针头外侧套有透明护帽,其特征在于:针孔孔壁设有与针头同轴的套状环形槽,还包括位于针头内的调节套,调节套嵌在环形槽内,调节套内壁截面为非圆形结构,针头侧壁和调节套套壁分别设有若干出液孔一和若干出液孔二,护帽上固定有调节杆,调节杆配合穿设在调节套内,且能通过围绕针头轴线旋转护帽,以通过调节杆带动调节套旋转,以使出液孔一和出液孔二错位、对齐或控制两者重合程度。可以将出液孔一和出液孔二对齐,以使本麻醉针实现多点注射,也可以通过围绕 ...
