摘要： A motorized syringe for use with two types of dental anesthetic solution-filled cartridges, having a plunger plug in the 1.8 ml cartridge pushed by a push rod by a length required to push a plunger plug in the 1.0 ml cartridge. The syringe includes a cartridge holder for use with 1.0 ml and 1.8 ml cartridges, the push rod having a 1.0 ml position and a 1.8 ml position drawn back from the 1.0 ml position so that push rod movement can end at a common terminal position for both, a sleeve adapted to receive the push rod rear end when pushed back from the common terminal position, and to be not interfered with by the push rod's rear end when it is in the 1.0 ml position, the sleeve being pushed rearward with the push rod's rear end when pushed back to the 1.8 ml position.
摘要翻译：一种用于两种类型的牙科麻醉剂溶液填充的药筒的电动注射器，其具有由推杆推动的1.8ml药筒中的柱塞塞，所述长度需要将柱塞塞推到1.0ml药筒中。注射器包括用于1.0ml和1.8ml药筒的药筒保持器，推杆具有1.0ml的位置和从1.0ml位置拉回的1.8ml位置，使得推杆运动可以在两个共同的终端位置终止，当从公共端子位置推回时适于接收推杆后端的套筒，当其处于1.0ml位置时不受推杆后端的干扰，套筒被推杆向后推动后推回到1.8毫升的位置。

摘要： Provided is an anesthetic solution-filled cartridge-type electric dental syringe, wherein the plunger has been shortened but the plunger can nevertheless be extended to the distance necessary to evacuate the anesthetic solution from the cartridge. The syringe comprises: an extension tube into which a plunger is movably inserted, the extension tube being movably disposed in the through hole of a support block and having racks formed in the side surface thereof that are coordinated with the racks of the plunger; and a means for the plunger to draw the extension tube to engage the racks of the extension tube with a pinion when the plunger reaches the middle of the distance corresponding to the anesthetic solution accommodation length of the cartridge. By the engagement of the racks of the extension tube with the pinion, the plunger moves together with the extension tube for the remainder of the distance corresponding to the anesthetic solution accommodation length of the cartridge.
摘要翻译：提供了一种充满麻醉剂的药筒型电动牙科注射器，其中柱塞已经被缩短，但是柱塞可以延伸到从药筒排出麻醉溶液所需的距离。注射器包括：延伸管，柱塞可移动地插入该延伸管中，延伸管可移动地设置在支撑块的通孔中，并且具有形成在其侧表面中的与柱塞的齿条配合的齿条; 以及当柱塞达到对应于药筒的麻醉剂溶液容纳长度的距离的中间时，柱塞的一个装置用于拉伸延伸管以与小齿轮接合延伸管的齿条。通过延伸管的齿条与小齿轮的接合，柱塞与延伸管一起移动距离对应于药筒的麻醉剂溶液容纳长度的剩余距离。

摘要： Provided is an anesthetic solution-filled cartridge-type electric dental syringe, wherein the plunger has been shortened but the plunger can nevertheless be extended to the distance necessary to evacuate the anesthetic solution from the cartridge. The syringe comprises: an extension tube (11) into which a plunger (5) is movably inserted, the extension tube being movably disposed in the through hole (14) of a support block (13) and having racks (15, 15) formed in the side surface thereof that are coordinated with the racks (9) of the plunger; and a means for the plunger to draw the extension tube to engage the racks (15, 15) of the extension tube with a pinion (21) when the plunger reaches the middle of the distance corresponding to the anesthetic solution accommodation length of the cartridge. By the engagement of the racks of the extension tube with the pinion, the plunger moves together with the extension tube for the remainder of the distance corresponding to the anesthetic solution accommodation length of the cartridge.
