技术领域technical field
本发明涉及医疗器械技术领域，具体涉及一种麻醉用注射器。The invention relates to the technical field of medical devices, in particular to a syringe for anesthesia.
背景技术Background technique
麻醉是实行手术或进行诊断性检查操作时为消除疼痛、保障病人安全、创造良好的手术条件而广泛采用的重要的辅助诊断手段，有时也用于控制疼痛以减轻伤害。在进行连续静脉注射麻醉时，需要分段定量进行注射，现有的定量注射都是依靠人肉眼观察注射针筒的刻度线来进行观察，误差较大，操作麻烦。Anesthesia is an important auxiliary diagnostic method widely used to eliminate pain, ensure patient safety, and create good surgical conditions when performing operations or diagnostic inspections. Sometimes it is also used to control pain and reduce injuries. When performing continuous intravenous anesthesia, it is necessary to perform quantitative injections in sections. The existing quantitative injections all rely on human eyes to observe the scale line of the injection syringe. The error is relatively large and the operation is troublesome.
专利号为200910228469.X的中国发明专利公开了一种一次性使用的连续多次定量注射器，针管外后端连接握柄，针管内装有推药活塞杆，留在针管外的活塞杆上依次装有推进板弹簧、推进板、导向套、制动弹簧和制动手柄；在导向套和制动手柄之间的制动弹簧外有限位板，导向套和限位板连接在握柄上方，中空的握柄内有扳动手柄，轴，扳动手柄装在中空的握柄内的扳动手柄轴上，扳动手柄上端紧靠在推进板的下端。使用本注射器省力，便于连续的间断定量注射操作。使用时只要一只手握住握柄，扳动扳动手柄，扳动手柄向前推动活塞杆，进行注射，当扳动手柄碰到换档凸杆时停止注射，达到定量注射。这种连续多次定量注射器的结构较复杂，实现连续定量注射的成本较高，且操作非常麻烦。The Chinese invention patent with the patent number 200910228469.X discloses a one-time use continuous multiple quantitative syringe. There are push plate springs, push plates, guide sleeves, brake springs and brake handles; there is a limiting plate outside the brake spring between the guide sleeve and the brake handle, and the guide sleeve and the limit plate are connected above the handle. A pull handle and an axle are arranged in the handle, and the pull handle is contained on the pull handle shaft in the hollow handle, and the pull handle upper end is close to the lower end of the propulsion plate. The use of the syringe saves labor and is convenient for continuous intermittent quantitative injection operations. When in use, as long as one hand holds the handle, the handle is pulled, and the handle is pushed forward to push the piston rod for injection. When the handle touches the shift lever, the injection is stopped to achieve quantitative injection. The structure of this continuous multiple quantitative injector is relatively complicated, the cost of realizing continuous quantitative injection is relatively high, and the operation is very troublesome.
