摘要： A dental syringe (10) has a needle (11) affixed to a carpule holder (12), which carpule holder (12) is affixed to a power drive unit (13). A harpoon (20) is provided to affix the drive unit to the carpule plunger (32). The harpoon (20) is made of stainless steel or other hard, corrosion resistant, sterilizable, material. Harpoon 20 has a unique barb geometry and hardened, knife-like, edges (21). The syringe (10) may operate to divide the delivery of anesthesia into two phases. According to the method, during the first about 10 seconds of the injection, anesthetic is delivered at an extremely slow rate to maximize patient comfort. The injection rate then automatically increases to the preprogrammed rate associated with the injection type selected.

摘要： The invention comprises a disposable hypodermic syringe with means for passive aspiration. The syringe comprises a barrel (10) of clear synthetic plastics material and a plunger (12) comprising an elastic bung (28) slideable in the barrel (10). Pressure on the plunger elastically deforms the bung (28). If this pressure is released the bung (28) resiles to effect aspiration. This aspiration is passive, requiring no active withdrawal of the plunger by the user. After use the syringe may be disposed of as a whole, with no disassembly, using one hand only. The syringe may be made by adapting cartridges conventionally used for dental local anaesthetic.

摘要： A dual chamber syringe in which a dual function piston divides the syringe into two compartments containing powder or fluid in one compartment and fluid in the other. For mixture of the two substances, a passage is opened between the two compartments before or during retraction of the piston to force the substances to be mixed in the front compartment. During forward movement of the piston, the passage between the two compartments is closed to force the mixture of substances through the discharge opening of the syringe.

摘要： A safe needle tube structure is mainly comprised of an injection tube, a connection seat, and an injection handle. A blocking-and-supporting portion is pivotally arranged in the front end of the injection tube. A connection seat is arranged inside the injection tube. And, a connection portion is pivotally arranged in the front end of the connection seat. Two ring troughs are arranged oppositely in the front end of the connection portion. A fitting-in portion is in integration and in extension arranged in the tail end of the connection seat. A gliding trough is cut and arranged inside the fitting-in portion. And, an injection handle is also arranged through the interior of the gliding trough. A fitting-in block is in integration and in extension arranged in the front end of the injection handle. If the injection handle is pulled backward, then the blocking-and-supporting portion at the front end of the injection tube will make the injection needle stay at the front end of the injection tube and the injection tube may suck in medicine for injection. After the medicine is injected, the injection handle is rotated an angle to make the ring trough of the connection portion and the ring block of the injection needle be jointed to one body. The injection handle is moved backward to tail end. The fitting block of the injection handle is separated from the gliding trough of the connection seat. The injection needle stays inside the injection tube to reach the safe injection and recycling.
摘要翻译：安全的针管结构主要由注射管，连接座和注射手柄组成。阻塞支撑部分枢转地布置在注射管的前端中。连接座设置在注射管的内部。并且，连接部分可枢转地布置在连接座的前端中。两个环形槽相对地设置在连接部分的前端。装配部分整合在一起，并且在连接座的尾端布置。滑动槽被切割并布置在装配部分内部。并且，喷射手柄也布置在滑动槽的内部。一个装配块在整体上并且在延伸部分布置在注射手柄的前端。如果注射手柄向后拉，则注射管前端的阻塞支撑部分将使注射针停留在注射管的前端，并且注射管可以吸入用于注射的药物。注射药物后，注射手柄旋转一定角度，使连接部分的环槽和注射针的环形块接合在一体上。注射手柄向后移动到尾端。注射手柄的装配块与连接座的滑动槽分离。注射针停留在注射管内，以达到安全注射和循环利用。

摘要： The present invention is directed toward a plunger provided for use in a nozzle assembly. The nozzle assembly includes an internal chamber with an outwardly tapered portion at one end thereof. The plunger includes a plurality of outwardly curved prongs or legs which mate with an inwardly tapered portion of the internal chamber in order to allow the piston of the injector to be released from the plunger. As a result, the plunger may be removed from the injector when the nozzle assembly is removed therefrom. This plunger may include a frangible portion so that, upon firing, a first driving member of the plunger breaks away from a second driving member of the plunger. As a result of this frangible connection, the first driving member remains lodged in a distal portion of the chamber to prevent reuse of the nozzle assembly.

摘要： A syringe assembly includes a substantially cylindrical syringe barrel and a plunger stopper. Distal portions on the plunger stopper are configured to permit outflow of vapor from the syringe barrel during a lyophilization process. Proximal portions of the plunger stopper are dimensioned to engage the syringe barrel in sliding fluid-tight engagement. Liquid medication in the chamber is lyophilized and a vacuum is applied to the syringe barrel after lyophilization. The plunger stopper then is urged distally into sealing engagement with the syringe barrel. A plunger rod can be engaged with the plunger stopper. The tip cap is then removed and a diluent is drawn into the chamber by moving the plunger rod and the plunger stopper in a proximal direction. The syringe assembly then can be used in the standard manner.
