摘要： A dental syringe and disposable capsule for use therewith wherein the disposable capsule includes a body portion formed with a laterally extending collar having a groove therein connected to one end and having a discharge nozzle connected at the other end of the capsule body portion. A displaceable plug seals the material within the cartridge. The syringe includes a plastic barrel having a bore extending therethrough for receiving a reciprocating plunger slidably supported therein. Connected to the barrel adjacent one end is a handle extending normal thereto with a lever pivotally connected relative thereto for engaging the end of the plunger for effecting the displacement of the plunger when the lever is actuated. Connected to the front end of the plastic barrel is a cartridge holder formed as a metal part having a rear portion and a forwardly extending seat portion. The rear portion is embedded into the material of the plastic barrel with the seat portion extending forwardly of the front end of the barrel. The seat portion is defined by an inturned flange spaced forwardly of the front end of the barrel which is notched to define a U-shaped opening. The upper end of the opening is provided with a width sized to the diameter of the groove formed in the collar of the capsule whereby the cartridge is removably retained within the cartridge seat in a simple and expedient manner by placing the collar groove in the notch defined by the inturned flange of the cartridge seat.
摘要翻译：一种牙科用注射器和一次性使用的胶囊，其中一次性胶囊包括主体部分，该主体部分形成有横向延伸的套环，其具有连接到一端的凹槽，并且具有连接在胶囊主体部分另一端的排出喷嘴。可移动的塞子密封墨盒内的材料。注射器包括具有延伸穿过其中的孔的塑料桶，用于容纳可滑动地支撑在其中的往复式柱塞。连接到相邻一端的筒体是与其相对延伸的手柄，其手柄与其相对枢转地连接，用于接合柱塞的端部，以在杆被致动时实现柱塞的移位。连接到塑料桶的前端的是具有后部和向前延伸的座部的金属部件形成的盒保持架。后部部分嵌入塑料桶的材料中，其中座部分向前延伸到桶的前端。座部分由位于筒体前端的向内间隔限定，该凸缘被切口以限定U形开口。开口的上端设置有一个宽度，该宽度尺寸与形成在胶囊的轴环中的凹槽的直径相比，通过将套环凹槽放置在凹口中来定位，该盒可以以简单和方便的方式可移除地保持在盒座内通过墨盒座的内翻法兰。

摘要： A dental syringe and disposable capsule for dispensing a dental material wherein the capsule includes a reservoir portion containing a predetermined amount of material to be dispensed, and which reservoir is connected in communication with a discharge tip. Connected to the end of the tip and projecting therethrough is a needle cannula through which the material is ejected. A displaceable piston, which seals the material within the reservoir portion, is provided to force the material through the cannula when displaced within the reservoir portion. The arrangement is such that the cannula connection within the tip end permits the cannula to be rotatably mounted relative to the tip while maintaining a seal between the tip and the cannula.

摘要： A disposable dental brush for applying various dental materials onto a tooth in thin even, coatings, e.g. etchants, sealants, bonding agents, tints, opaquers, varnishes and the like that includes an elongated straight handle having a tuft of bristles connected to one end thereof. The elongated handle is constructed so as to allow the portion thereof adjacent to the brush end to be readily bent so as to angularly dispose the brush end relative to the longitudinal axis of the handle. The arrangement is such that the brush can be used either as a straight brush or an angularly bent brush to reach difficult areas of the mouth or teeth. Also, the brush is made of inexpensive plastic material so as to render it readily expendable or disposable after each use.

摘要： A manual extruder or syringe having a longitudinal slot therein adjacent the full circumference front end for receiving the nozzle of a cartridge. A barrel of a syringe having a front end and a breach opening adjacent thereto for receiving a cartridge of the type having an angularly disposed nozzle and rear flange. The slot in the front end is only wide enough to receive the width of the nozzle and prevents the body portion of the cartridge from passing therethrough. The body portion can then easily be slid along the barrel into the front end to be held by the flange against a substantially full circumference shoulder. The front end can be made very rigid, and the shoulder extending substantially the full circumference of the front end securely holds the cartridge preventing any possibility of unintentional separation from the syringe. In one embodiment, a notch is also provided to permit the cartridge to be inserted with the nozzle pointing upward. In another embodiment, a track or guide is provided along the slot to help guide the body portion of the cartridge past the shoulder.
摘要翻译：一种手动挤出机或注射器（10），其具有在其周围的全圆周前端的纵向狭槽（36），用于接收墨盒（20）的喷嘴。注射器的筒体（14）具有与其相邻的前端（12）和后膛开口（34），用于容纳具有角度设置的喷嘴（50）和后凸缘（42）的类型的药筒。前端中的狭槽（36）仅足够宽以容纳喷嘴（50）的宽度，并防止墨盒（20）的主体部分（38）穿过其中。主体部分（38）然后可以容易地沿着筒体（14）滑动到前端，以被凸缘保持抵靠基本上全圆周的肩部（32）。前端可以制成非常刚性的，并且基本上前端的整个圆周延伸的肩部牢固地保持盒，防止任何从注射器意外分离的可能性。在一个实施例中，还提供凹口（46）以允许墨盒插入，喷嘴指向上方。在另一个实施例中，沿着狭槽设置轨道或引导件，以帮助引导卡盘的主体部分经过肩部。

摘要： A dental capsule for mixing a cement powder with an activating liquid having a frangible seal. The frangible seal is placed between a nozzle and the body portion of a capsule preventing unmixed cement from entering the nozzle. The nozzle has a circumferential groove facilitating positioning thereof. A vent formed in the body of the capsule prevents premature rupturing of the frangible seal upon insertion of the plug. A second and third embodiment use a two-part plug for dispensing activating liquid to the cement powder contained within the body of the capsule.

摘要： This disclosure is directed to a dental syringe having a capsule holder and a plunger for accurately and precisely placing a viscous or low viscosity composite resin dental restorative material from a capsule directly into a tooth. The improvement resides in a plunger having an ejector tip which is maintained under a positive bias that is intended to retract when a resistance exceeding a predetermined amount is met during an ejecting procedure so as to prevent any build-up of pressure within the capsule containing the material to be dispensed that may tend to distort or rupture the capsule. In the case of a low viscosity resin, the plunger having an ejector tip maintained under a positive bias that is intended to retract when the speed of ejection exceeds that of a predetermined rate, so as to prevent sudden and excessive extrusion of material from the capsule. The capsule containing the viscous material may also be provided with a reinforced body portion to further aid in resisting any built-up internal pressure within the capsule during an ejecting procedure. The capsule may also include orientation notches formed on the flange for engaging a stop detent for positively maintaining the capsule in a predetermined oriented angular position relative to the holder.
摘要翻译：本公开涉及一种具有胶囊保持器和柱塞的牙科用注射器，用于将粘性或低粘度复合树脂牙科修复材料从胶囊直接准确地精确地放置到牙齿中。改进之处在于具有顶喷头的柱塞，其在喷射过程中当达到超过预定量的阻力时保持在正偏压下旨在缩回，以防止在包含喷射器的胶囊内的任何压力积聚待分配的材料可能会使胶囊变形或破裂。在低粘度树脂的情况下，具有顶喷头的柱塞保持在正偏压下，当喷射速度超过预定速率时，其旨在缩回，以防止材料从胶囊突然和过度挤出。包含粘性材料的胶囊还可以设置有增强体部分，以进一步有助于在喷射过程期间抵抗胶囊内的任何累积的内部压力。胶囊还可以包括形成在凸缘上的定向凹口，用于接合止动止动件，用于将胶囊积极地保持在相对于保持器的预定取向角位置。

摘要： A vascular dilating device for performing a coronary angioplasty procedure that includes a tubular barrel defining a reservoir for containing a supply of actuating fluid and having a plunger and connected piston reciprocially disposed within the reservoir. The outlet of the reservoir is connected to a valve assembly having an outlet to which a balloon catheter is connected. The valve assembly includes a control valve and a unidirectional valve which are co-operatively associated for directing fluid from the reservoir to the balloon catheter in one direction only when the control valve is disposed in a balloon inflating position and the handle is actuated to advance the plunger. A by-pass is also provided in the valve assembly to reverse the fluid flow from the balloon catheter to the reservoir when the control valve is disposed in a second or balloon deflating position. The handle construction includes a actuating lever member disposed in bearing or driving relationship to the plunger so as to impart a mechanical advantage necessary to develope the desired or optimum pressures. A pressure gage is operatively connected to the valve assembly for indicating the pressure of the fluid acting on the balloon catheter.
