摘要： An adjustable flow syringe is provided that comprises a slidable plunger within a barrel. The barrel has a flow discharge end wherein a neck is located. The neck has a conduit extending therethrough which has an outlet and an inlet such that the conduit is in fluid communication with the barrel.The adjustable flow syringe includes either a valve insert or a porous insert in the conduit which is configured to adjust the flow rate of a fluid leaving the syringe such that a low amount of manually applied force delivers the fluid in drops. The valve insert is formed from a resilient material and conforms to the contours of the conduit. The valve insert has a portion that extends across the conduit outlet with an opening formed therethrough. The porous insert is formed from a porous material and is configured with a shape corresponding to the shape of the conduit so that fluid passes through the conduit primarily via the pores of the porous insert.

摘要： A syringe is provided that has an opaque barrel and a light colored outlet portion. The opaque barrel protects dental composite material or other light-activating material contained in the barrel from premature exposure to light. The light colored outlet portion has a color that is similar to that of the dental composite material. The outlet portion may be tubular and extend coaxially within the barrel beyond the barrel. The outlet portion may include a divider that divides the material into at least two separate portions.

摘要： An annular sealing ring with a generally Y-shaped cross-section for sealing between a piston and the curved wall of a cylinder. The sealing ring includes a base with one or more horizontal ribs extending outwardly from each side thereof and a pair of lips with sealing edges, the lips being spaced apart to form a cavity therebetween wherein a solid, elastic expander ring is retained. The cavity is bounded by the similarly opposed inner surface of the lips. The expander ring is seated in a portion of the cavity so that a void is created in the cavity below the expander ring.

摘要： A syringe is provided for delivering compositions having a hollow elongated barrel engaged by a plunger with a unique plunger tip. The plunger tip extends from a round and hollow sidewall of the stem of the plunger by bifurcating into an inset branch and a spring lever. The inset branch and the spring lever define a radial tensioning groove. The lower portion of the spring lever is flat while the upper portion of the spring lever flares outward at an angle with respect to the lower portion and then terminates at a rounded distal contact end. As a result, the diameter of the spring lever at the rounded distal contact end is slightly greater than the diameter of the inside of the barrel before the plunger is inserted into the barrel. The spring lever is sufficiently flexible that upon insertion of the plunger into the chamber of the barrel, the radial tensioning groove compresses due to the spring lever flexing toward the inset branch. The spring lever is also sufficiently rigid to enable the rounded distal contact end to be exerted against and to form a seal with the interior of the barrel.
摘要翻译：提供了一种注射器，用于输送组合物，该组合物具有由具有独特柱塞尖端的柱塞接合的中空细长筒体。柱塞末端通过分叉成插入分支和弹簧杆从柱塞杆的圆形和中空的侧壁延伸。插入分支和弹簧杆限定一个径向张紧槽。弹簧杆的下部是平的，而弹簧杆的上部相对于下部以一定角度向外张开，然后终止于圆形的远端接触端。结果，在柱塞插入筒体之前，圆形远端接触端处的弹簧杆的直径略大于枪管内部的直径。弹簧杆具有足够的柔性，使得当柱塞插入筒的腔室中时，径向张紧槽由于弹簧杆朝着插入分支弯曲而压缩。弹簧杠杆也具有足够的刚性，以使圆形的远端接触端能够抵靠并与筒的内部形成密封。
