    Abstract: A syringe includes a barrel, a plunger, and a sealing member creating a seal between the plunger and the barrel. The barrel includes a first portion with a first inner diameter and a second portion with a second inner diameter that is larger than the first inner diameter. The sealing member engages the first portion of the barrel to give rise to a first contact pressure when the barrel is filled with product. The first contact pressure is sufficient to maintain a gas-tight seal over the expected temperature ranges −25° C. to 40° C. A first force is applied to the plunger to overcome the first contact pressure and move the plunger out of the first portion and into the second portion to dispense product. The sealing member engages the second portion of the barrel to give rise to a second contact pressure that is lower than the first contact pressure. A second force lower than the first force is sufficient to overcome the second contact pressure and move the plunger in the second portion to continue dispensing product. The syringe may include a restraining element for accommodating expansion of the product during freezing.

    Abstract: A protective sleeve placed within the cylinder of a syringe, the sleeve protects a piston and a computer controlled device or human operator pushing the piston from material leaking past a piston assembly. The sleeve has lips or ridges at either end, one that is attached to the piston assembly at the output end of the syringe and a second lip that is attached with a retention plate at the far end of the syringe. The sleeve may have a bellows or accordion configuration that slides along the inner surface of the syringe cylinder without appreciably loading the drive mechanism.

    Abstract: The invention relates to a cylinder/piston unit having a cylinder and a piston which is guided therein, wherein the cylinder and the piston enclose a chamber which can be filled at least for a time with an additive, and the cylinder has at least one exit element at its front end. Here, the cross section of the chamber or the cross section of the cylinder inner wall is increased at least in regions of the cylinder from the front to the back, wherein the cylinder end having the exit element is at the front. The piston has an elastic skirt at least in the front region, the front outer edge of said elastic skirt defining a cross-sectional area in the case of an unloaded piston, which is greater than an area which is defined by a contour line. The present invention develops a cylinder/piston unit which ensures simple and reliable handling and can be stored for a long time in the filled state, in a manner which is impervious to gas and moisture.

    Abstract: An intravenous catheter placement device having a hollow body and a nose on one end of the hollow body. A needle hub fits within the nose and contains a needle embedded therein. A catheter is free to slide along the needle and substantially covers the shaft of the needle. Winged beams on the needle hub include catches and release tabs that cooperate with slots in the nose to retain the needle hub in the nose. A magnified transparent verification cavity in the needle hub provides for viewing blood flash in the cavity to verify that the intravenous catheter is inserted into the correct location. An energy storage device in contact with the needle hub releasably retains the needle hub to prevent premature projection of the needle hub into the hollow body. Upon insertion of the intravenous catheter and introducer needle into a patient, depressing the release tabs triggers the needle hub and blunts the needle within the catheter and projects the needle hub and embedded needle into the hollow body.

    Abstract translation: 一种在中空体的一端具有中空体和鼻部的静脉导管置放装置。 针座适合于鼻子内，并包含嵌入其中的针。 导管可以沿着针自由滑动并且基本上覆盖针的轴。 针座上的翼梁包括与鼻子中的狭槽配合的卡扣和释放卡舌，以将针座保持在鼻子中。 针座中的放大的透明验证腔提供观察腔中的血液闪烁，以验证静脉内导管插入正确的位置。 与针座接触的能量存储装置可释放地保持针座，以防止针毂过早地突出到中空体中。 当将静脉内导管和导引针插入患者体内时，按压释放舌片会触发针头针头并钝化导管内的针头，并将针座和嵌入针头突出到中空体中。
